SUMMARY   OF   THE   VOYAGE, 


IN  the  beginning  of  the  year  1839,  the  British  Government  having  determined  on  fit- 
ting out  an  Expedition,  for  the  purpose  of  investigating  the  phenomena  of  Terrestrial 
Magnetism  in  various  remote  countries,  and  for  prosecuting  Maritime  Geographical 
Discovery  in  the  high  southern  latitudes,  H.M.  Ships  Erebus  and  Terror,  commis- 
sioned by  Captain  Sir  James  Clark  Ross,  sailed  from  Chatham  on  the  29th  of  Sep- 
tember 1839.  In  addition  to  carrying  out  the  above-mentioned  leading  views,  it  was 
enjoined  to  the  officers,  that  they  should  use  every  exertion  to  collect  the  various  objects 
of  Natural  History  which  the  many  heretofore  unexplored  countries  about  to  be  visited 
would  afford. 

On  the  outward  voyage  we  touched  at  most  of  the  Atlantic  Islands,  making  a 
longer  stay  at  some  of  them  than  is  usual,  on  account  of  the  nature  of  the  observations 
that  were  instituted.  At  Madeira,  which  was  tbe  first  visited,  we  called  in  the  middle 
of  October,  and  remained  eleven  days  ;  and  then  made  Teneriffe  and  the  Cape  de  Verds, 
whence  we  sailed  for  and  landed  upon  St.  Paul's  Rocks*,  under  the  Line,  in  long. 
29°  W.  St.  Helena  was  the  next  destination,  and  the  course  which  it  was  found  ne- 
cessary to  follow  took  us  to  the  Island  of  Trinidad  off  the  Brazilian  coast,  lat.  20°  S. 

After  spending  a  week  at  St.  Helena,  the  vessels  sailed  for  the  Cape  of  Good  Hope, 
arriving  there  on  the  4th  of  April  1840.     The  Cape  may  be  regarded  as  the  starting-

point,  whence  the  real  object  of  the  voyage,  namely  that  which  included  South  Polar 
Discovery,  would  commence.  On  the  6th  of  April  1840  we  quitted  Simon's  Bay, 
and  first  entered  a  cold  and  inhospitable  latitude  (42°  S.)  on  the  17th  of  the  same 
month  ;  then,  only  four  days  after,  holding  a  westward  course,  we  passed  to  the 
south  of  Marion's  Island,  formed  of  fiat  terraces  of  black  volcanic  rock  and  cone-shaped 
mountains,  often  of  a  reddish  tinge,  and  towering  to  a  considerable  height.  Here  oc- 
curred the  first  botanical  phenomenon,  the  Macrocystis  pyrifera  (a  remarkable  gigantic 
seaweed),  being  exceedingly  abundant.  The  ships  were  hove  to  between  Marion's  and 
Prince  Edward's  Islands,  with  the  view  to  going  ashore  the  following  day  ;  but  during 
the  night  a  heavy  gale  arose  which  drove  them  far  to  the  westward,  thus  disappointing 
the  hopes  which  had  been  formed  of  collecting  objects  of  natural  history  on  an  island 
never  previously  explored  by  any  scientific  individual. 

On  the  28th,  after  a  succession  of  storms,  the  Crozet  Islands  were  gained  :  this 
group  lies  far  to  the  westward  of  the  position  that  had  been  assigned  to  it,  namely  in 
lat.  47^°  S.  and  long.  46-48°  E. ;  and  here  the  same  disappointment  awaited  us,  for  after 
being  blown  off,  and  again  on  the  1st  of  May  beating  up  to  Possession,  the  most  east- 
ern of  the  cluster,  the  threatening  appearance  of  the  weather  forbade  any  attempt  to 
land.  The  Crozet  Islands  are  all  volcanic,  and  of  the  wildest  and  most  rocky  aspect ; 
the  harbours  are  very  few,  and  some  of  the  islands  are  entirely  inaccessible.  The 
mountains  rise  in  peaks  and  cones  to  an  elevation  of  4000-5000  feet,  exhibiting  patches 
of  perpetual  snow  on  the  summits,  while  dense  fogs  frequently  envelope  their  bases, 
borne  from  the  sea,  to  such  an  elevation,  that  the  highest  points  alone  are  visible.  To 
all  appearance  the  vegetation  is  equally  scanty  and  stunted  as  that  which  Kerguelen's 
Island  afterwards  afforded,  and  the  questions  which  were  put  to  a  party  of  miserable 
sealers  who  came  off  to  the  ship,  elicited  no  satisfactory  information  as  to  whether  the 
valuable  "Cabbage"  of  the  latter  island  also  inhabits  the  Crozet  group.  Scudding  before 
heavy  westerly  gales,  on  the  6th  of  May  a  remarkable  conical  rock,  called  Bligh's  Cap, 
was  descried  ;  it  lies  off  the  north-west  extremity  of  Kerguelen's  Island  ;  but  thick 
weather  prevented  Sir  James  Ross  from  making  the  land,  from  which  the  ships  were 
again  driven  to  a  distance  of  150  miles  and  obliged  to  beat  back,  finally  casting  anchor 
in  Christmas  Harbour,  on  the  12th  of  May  1840. 

At  Kerguelen's  Island,  all  the  plants  that  had  been  originally  detected  by  the  illus-

trious  Cook  were  gathered  during  the  two  and  a  half  winter  months  that  the  "  Erebus 
and  Terror"  staid  there,  together  with  many  other  species,  a  remarkable  proof  of  the 
uniformity  of  the  climate,  and  the  comparative  mildness  of  the  winter  season.  The  ships 
left  Kerguelen's  Island  on  the  20th  of  July,  and  arrived  in  the  river  Derwent,  Van 
Diemen's  Island,  on  the  16th  of  August  1840. 

On  the  12th  of  November  1840,  we  quitted  Hobarton  for  our  first  voyage  to  the 
South  Pole,  during  which  the  only  places  visited  which  yielded  many  plants  were 
Lord  Auckland's  Islands,  lat.  50|°  S.,  long.  166°  E.,  where  we  arrived  after  a  week's 
sail  from  the  last-mentioned  coast,  and  staid  there  during  the  spring  months  of  that 
latitude,  and  Campbell's  Island,  in  lat.  52J°  S.,  long.  169°  E.  Quitting  that  island 
again  on  the  17th  of  December,  the  ships  finally  sailed  for  an  entirely  unexplored  region 
of  discovery.  The  Macrocystis  and  D'Urvillcea  were  found  in  large  vegetating  floating 
patches,  nearly  as  far  south  as  any  open  water  remained  free  of  bergs,  in  lat.  61°  S.  The 
vessels  entered  the  pack-ice  in  lat.  68°  S.,  long.  175°. 

During  this  voyage  the  vast  extent  of  continent,  since  called  "Victoria  Land," 
was  discovered*,  together  with  the  active  volcano  "  Mount  Erebus,"  the  extinct  one 
"  Mount  Terror,"  and  that  icy  barrier,  which,  running  east  and  west,  in  the  parallel  of 
78°  S.,  prevents  all  farther  progress  towards  the  polef.  Two  small  islets  were  landed 
upon  :  one  in  lat.  71°  49'  S.,  long.  170°  52' E.  ;  the  other,  Franklin  Island,  in  lat.  76°  S. 
and  long.  168°  59'  E.  ;  but  neither  of  these  spots  presented  the  slightest  trace  of  vege- 
tation. On  the  return  voyage  the  Macrocystis  again  occurred,  floating  as  usual  in  im- 
mense masses,  in  lat.  51°  10'  S.,  and  long.  137°  E. 

The  expedition  returned  to  Hobarton,  Van  Diemen's  Island,  late  in  the  autumn 
(of  that  latitude),  April  7th,  1841  ;  on  the  7th  of  July  again  started  from  Van  Die- 
men's  Island,  and  after  a  short  visit  to  Sydney,  cast  anchor  in  the  Bay  of  Islands,  New 
Zealand,  August  18th,  1841,  where  we  remained  three  months.  This  time  was  spent 
in  collecting  materials  for  a  Flora  of  New  Zealand,  in  which  object  we  received  great 
assistance  from  Mr.  Colenso  and  many  other  gentlemen,  by  means  of  whose  zealous 
cooperation  our  collections  were  rendered  extremely  valuable. 

The  second  exploring  voyage  was  commenced  on  the  15th  of  November  1841.  It 
had  been  Captain  Ross's  intention  to  land  on  Chatham  Island,  in  lat.  44°  S.  and  176°

W. ,  but  the  prevalence  for  several  days  of  the  densest  fogs  frustrated  all  attempts  to 
sight  the  land.  This  was  much  regretted,  for  few*  of  the  plants  of  that  interesting 
group  are  known  to  botanists.  After  tracing  the  Macrocystis  into  the  57th  parallel,  tbe 
ships  entered  an  ice-pack  of  immense  magnitude  on  the  18th  of  December,  in  lat.  62°  S. 
Here  we  were  entangled  till  Feb.  2nd,  1842  (the  midsummer  of  those  cheerless  re- 
gions), making  no  more  progress  during  that  time  than  from  the  latitude  just  mentioned 
to  68°,  where  we  emerged  into  comparatively  open  water  to  the  southward  of  a  large 
body  of  the  pack,  which  however  trended  to  the  westward.  At  this  time  the  season 
was  far  advanced,  and  as,  in  the  preceding  year,  the  retreat  had  been  commenced,  through 
absolute  necessity,  on  the  9th  of  February,  so  Captain  Ross  did  not  think  proper  now 
to  re-enter  the  pack-ice,  but  proceeded  along  its  edge  to  the  westward,  advancing  so  far 
as  187°  W.,  and  then  to  the  southward  and  eastward.  On  the  20th  of  February  a  gale 
came  on,  which,  though  in  open  water,  was  sufficiently  trying  ;  the  wind  was  very  high, 
and  the  spray  which  beat  over  the  ships  became  frozen  ere  it  reached  the  deck,  forming 
every  object  into  a  mass  of  ice  ;  the  coils  of  rope  were  covered  by  an  icy  incrustation 
several  inches  thick,  and  most  of  the  running-gear  about  the  bowsprits  was  carried 
away  by  the  weight  of  ice  formed  on  it. 

On  the  23rd  of  February  the  expedition  came  in  view  of  the  grand  Victoria  Barrier  : 
the  day  being  fine,  the  voyagers  approached  within  a  mile  and  a  half  of  the  Barrier,  finally 
reaching  78°  10'  S.  lat.  in  the  long.  162°  W.,  having  made  six  miles  farther  than  in  the 
preceding  year,  the  highest  latitude  hitherto  attained.  Under  all  circumstances,  this 
was  more  than  had  been  expected  ;  for  after  the  long  detention,  the  rapidly  closing  sea- 
son rendered  any  progress  very  difficult ;  but  it  was  a  great  object  to  verify  the  magnetic 
and  other  observations,  and  to  ascertain  still  more  positively  the  position  of  the  pole. 
Unable  to  proceed  eastward,  the  retreat  was  commenced,  tracing  the  pack  edge.  Sea- 
weed was  again  met  with  on  reaching  the  parallel  of  64°,  and  occasionally  seen  when 
running  down  the  parallel  of  60°,  from  170°  W.  to  80°  W.,  and  thence  in  great  abun- 
dance to  the  Falkland  Islands,  where  the  ships  anchored  in  Berkeley  Sound  on  the  6th 
of  April  1842,  not  having  seen  land  for  138  days,  since  leaving  New  Zealand. 

A  prolonged  stay  in  the  Falklands,  though  the  season  was  winter  (April  to  the 
beginning  of  September),  afforded  ample  opportunities  for  thoroughly  investigating  the

Flora  of  that  interesting  and  now  highly  important  group,  which,  though  it  had  heen 
partially  examined  by  Admiral  D'Urville,  and  previously  by  the  officers  of  that  unfor- 
tunate ship,  the  "  Uranie,"  under  the  command  of  Captain  Freycinet,  still  afforded 
considerable  novelty. 

On  the  Gth  of  September,  the  early  spring  of  the  southern  latitudes,  the  "  Erebus 
and  Terror,"  with  a  portion  of  the  officers,  sailed  from  Berkeley  Sound  for  the  neighbour- 
hood of  Cape  Horn,  and  arrived  there,  after  having  been  driven  far  out  of  their  course  by 
the  equinoctial  gales,  on  the  2 1  st,  casting  anchor  in  St.  Martin's  Cove,  Hermit  Island,  lat. 
56°,  within  a  few  miles  of  the  far-famed  Cape  Horn,  which  is  immediately  opposite  the 
mouth  of  the  Cove.  This  is  the  most  southerly  spot  on  the  globe  which  possesses  any- 
thing above  a  herbaceous  vegetation.  Here,  in  the  sheltered  bays,  the  two  kinds  of 
Antarctic  Beech,  the  Evergreen  and  Deciduous,  form  a  dense,  though  small  forest,  and 
ascend,  in  a  stunted  form,  to  an  elevation  of  1000  feet  on  the  hills.  Many  of  the  plants 
gathered  during  Cook's  first  voyage,  by  Sir  Joseph  Banks  and  Solander,  and  by  Forster 
during  his  second,  as  also  those  which  Mr.  Menzies  had  detected,  when  accompanying 
Vancouver's  expedition,  and  which  have  not  been  hitherto  published,  were  found  again  ; 
and  when  the  ships  returned  to  the  Falklands  in  November,  Captain  Ross  transported 
many  hundreds  of  young  Beech-trees  and  caused  them  to  be  planted  there,  in  hopes  that 
the  productions  of  so  near  a  country  might  be  found  to  succeed  on  these  treeless  islands. 
Some  were  also  sent  home  and  have  since  been  distributed  in  England,  from  the  Royal 
Botanic  Gardens  of  Kew. 

The  third  cruise  to  the  South  Polar  Regions  was  commenced  on  the  morning  of 
the  17th  of  December  1842,  when  the  expedition  sailed  from  Berkeley  Sound.  An  op- 
portunity was  afforded  again  of  tracing  the  southern  limit  of  Seaweeds.  The  Macro- 
cystis  was  lost  in  lat.  55°  S.,long.  57°  W.  ;  but  on  attaining  lat.  63°,  long.  54°,  another 
species  appeared  which  had  been  originally  discovered  by  Webster  during  the  stay  of 
Captain  Forster's  ship,  the  "  Chanticleer,"  in  Deception  Island,  one  of  the  South  Shetland 
group,  and  again  found  by  the  expedition  of  Admiral  D'Urville,  and  has  since  been  pub- 
lished under  the  name  of  Scytothalia  Jucquinotii.  On  the  28th  land  was  made,  a  por- 
tion of  Palmer's  Land,  to  which  the  name  of  "  Terre  Louis  Philippe"  has  since  been 
given  by  D'Urville.  The  ships  were  already  in  the  pack-ice,  through  which  we  pene- 
trated, tracing  the  Lnd  to  64°,  and  seeing  a  small  volcanic  island,  lying  a  few  miles  off 


X  SUMMARY   OF  THE   VOYAGE. 

the  coast  (Cockburn's  Island),  we  landed  upon  it.  The  vegetable  productions  only 
amounted  to  twenty  Cryptogamic  species,  three  of  them  Seaweeds.  Unable,  after  a 
series  of  fruitless  efforts,  to  penetrate  farther  than  65°,  and  after  having  been  more  or 
less  entangled  in  the  ice  for  thirty-seven  days,  Sir  James  Ross  finally  bore  up,  and  when, 
with  great  difficulty,  the  ships  had  been  extricated  from  the  pack-ice,  we  commenced 
tracing  its  edge  to  the  eastward.  A  succession  of  easterly  gales  rendered  the  pro- 
gress in  the  advancing  season  tedious,  most  uncomfortable,  and  hazardous.  At  last 
however,  on  the  22nd  of  February  1843,  the  pack  was  lost  sight  of,  trending  to  the  south- 
west. On  the  28th  the  Antarctic  Circle  was  recrossed,  and  in  spite  of  the  rapidly 
shortening  days,  dark  nights,  and  continual  bad  weather  (for  throughout  the  month 
of  February,  corresponding  to  an  English  August,  only  one  day  elapsed  without 
snow),  the  Commander  persevered  in  holding  a  southerly  course.  On  Sunday  the  5th 
of  March,  the  weather  being  very  thick,  with  snow-squalls,  white  petrels  were  seen,  a 
bird  whose  appearance  affords  a  sure  indication  of  the  proximity  of  pack-ice,  and  on 
the  afternoon  of  the  same  day  a  heavy  pack  was  descried,  only  a  few  yards  ahead,  with 
a  terrific  surf  beating  on  it.  The  ice  here  was  such  as  not  to  allow  of  being  "  taken" 
(or  entered),  even  under  the  most  favourable  circumstances,  and  the  ships  were  accord- 
ingly put  about  in  lat.  71°  30'  S.,  long.  15°  W. 

The  thickness  of  the  weather  made  it  impossible  to  ascertain  the  course  and  posi- 
tion of  the  pack,  and  the  Northward  Voyage  was  commenced  under  violent  N.E.  equi- 
noctial gales.  Beating  to  the  northward,  the  ice  occurred  on  both  tacks,  and  the  vessels 
were  found  to  be  in  a  bight  of  the  pack,  with  the  ocean  loaded  with  bergs,  and  while  the 
continued  snow-squalls  prevented  the  possibility  of  seeing  any  object  ahead,  the  heavy 
seas  and  snow-laden  state  of  the  rigging  rendered  all  human  exertions  ineffectual.  From 
that  date  till  the  11th  of  March,  matters  remained  much  the  same,  the  ships  beating  to 
the  northward  with  as  much  press  of  sail  as  could  be  exposed,  trusting  to  Providence 
alone  for  guidance  among  the  bergs.  On  the  1 9th  the  position  assigned  to  Bouvet's 
or  Circumcision  Island  was  gained,  but  the  weather  rendered  all  endeavours,  for  three 
days,  to  discover  land  in  this  place  of  no  avail.  Both  ships  had  a  narrow  escape  of 
running  foul  of  an  iceberg,  over  which  the  sea  was  breaking,  eighty  feet  high.  The 
"Erebus,"  passing  to  windward,  struck  one  of  the  floating  masses  from  it  ;  and  the 
"Terror,"  to  windward  of  her  consort,  did  not  discover  the  danger  till  almost  too  late,

when  bearing  up,  she  ran  along  the  edge  of  the  berg  in  the  wash  of  the  surf.  On 
the  24th  D'Urvillcea  and  Macrocystis  were  seen  in  lat.  51°  S.,  and  the  last  berg  on 
March  25th,  in  lat.  47°  S.,  the  ships  finally  gaining  the  Cape  of  Good  Hope  on  the 
4th  of  April  1843,  within  two  days  of  three  years  after  they  had  first  quitted  that  port 
for  the  high  southern  latitudes. 

Respecting  the  climate  of  the  various  regions  visited  by  the  expedition,  and  especially 
that  which  prevails  within  the  Antarctic  Circle,  little  need  here  be  said  ;  except  that  the 
vast  proportion  which  water  bears  to  land,  tends  to  render  the  temperature  uniform 
throughout  the  year,  and  the  farther  south  is  the  position,  the  more  equable  does  the 
climate  seem  to  be.  No  analogy  can  prove  more  incorrect  than  that  which  compares 
the  similar  degrees  of  latitude  in  the  north  with  those  of  the  south.  The  most  casual 
inspection  of  the  map  suffices  to  show  the  immense  proportion  of  sea  to  land  in  the 
southern  hemisphere,  the  mass  of  the  continents  terminating  to  the  north  of  lat.  40°  S., 
America  alone  dwindling  away  to  the  fifty-sixth  degree.  The  scattered  islands  dis- 
covered to  the  south  of  this  are  therefore  removed  from  the  influence  of  any  tracts  which 
enjoy  a  better  or  continental  climate.  The  power  of  the  sun  is  seldom  felt,  and  unless 
in  the  immediate  neighbourhood  of  land,  and  accompanied  by  a  comparatively  dryland- 
wind,  that  luminary  only  draws  up  such  mists  and  fogs  as  intercept  its  rays.  After 
entering  the  pack-ice  between  55°  and  65°,  the  thermometer  seldom,  during  any  part 
of  the  summer  day,  rises  above  32°  or  falls  below  20°  ;  and  while  the  southerly  winds 
bring  snow,  the  northerly  ones  transport  an  atmosphere  laden  with  moisture,  which, 
becoming  at  once  condensed,  covers  the  face  of  the  ocean  with  white  fogs  of  the  densest 
description. 

All  islands  and  lands  to  the  southward  of  45°  partake  more  or  less  of  this  inhospi- 
table climate,  which,  though  eminently  unfavourable  to  a  varied  growth  of  plants,  still, 
from  its  equable  nature,  causes  a  degree  of  luxuriance  to  pervade  all  the  vegetable  king- 
dom, such  as  is  never  seen  in  climates  where  the  vegetable  functions  are  suspended  for 
a  large  portion  of  the  year.  The  remoteness  of  these  islands  from  any  continent,  to- 
gether with  their  inaccessibility,  preclude  the  idea  of  their  being  tenanted,  even  in  a 
single  instance,  by  plants  that  have  migrated  from  other  countries,  and  still  more 
distinctly  do  they  forbid  the  possibility  of  man  having  been  an  active  agent  in  the  dis- 
semination of  them.     On  the  contrary,  the  remarkable  fact  that  some  of  the  most

peculiar  productions  are  confined  to  the  narrowest  limits,  is  a  strong  argument  in  favour 
of  a  general  distribution  of  vegetable  life  over  separate  spots  on  the  globe.  Hence  it 
will  appear,  that  islands  so  situated  furnish  the  best  materials  for  a  rigid  comparison  of 
the  effects  of  geographical  position  and  the  various  meteorological  phenomena  on  vege- 
tation, and  for  acquiring  a  knowledge  of  the  great  laws  according  to  which  plants  are 
distributed  over  the  face  of  the  globe.  These  subjects  are  however  foreign  to  the  pre- 
sent sketch,  the  author  of  which  hopes,  ere  long,  to  have  an  opportunity  of  dwelling 
upon  them  at  large  and  in  a  different  form. 

Those  persons  who  have  spent  a  series  of  years  on  the  ocean,  in  pursuit  of  a  favourite 
science,  know  how  little  can  be  effected  by  the  unaided  efforts  of  one  individual,  and 
where  much  is  accomplished,  how  large  is  the  debt  of  obligation  incurred,  not  only  to  the 
facilities  afforded  by  shipmates,  but  to  the  accommodating  disposition  of  those  with 
whom  he  comes  in  daily  contact,  and  with  whom  he  literally  shares  one  cabin  and  one 
table.  The  author  may  here  be  allowed  to  say,  that  no  man  can  be  more  deeply  sensible 
than  he  is  of  the  rare  privilege  he  enjoyed,  in  having  messmates  who  were  ever  ready 
to  sacrifice  their  own  convenience  for  his  accommodation.  Most  especially  does  he  feel 
it  incumbent  on  him  here  to  return  his  thanks  to  the  commanding  Officer  of  the  expe- 
dition (as  is  his  first  duty)  for  the  opportunity  afforded  of  accompanying  him,  for  the 
kindness  always  shown  during  this  the  most  important  and  interesting  scientific  voyage 
that  has  been  accomplished  since  the  days  of  Cook,  and  for  the  generous  manner  in 
which  that  officer's  private  cabin  and  library  were  unreservedly  placed  at  his  disposal 
during  the  whole  time  the  expedition  was  afloat.  Attached  as  Sir  James  Clark  Ross  has 
ever  been  to  the  various  branches  of  Natural  History,  he  took  a  pleasure  in  promoting 
the  interests  of  the  collections  at  all  times,  and  himself  gathered  many  of  the  plants 
here  described. 

There  were  few  of  the  officers  of  either  ship  who  did  not  contribute  something  to 
the  collection  of  plants  ;  but  the  botanist  feels  it  peculiarly  imperative  on  him  here  to 
enumerate  and  return  his  especial  thanks  to  Mr.  Lyall,  Lieut.  Smith,  and  Mr.  Davis. 
Mr.  Lyall  indeed,  as  appointed  to  take  charge  of  the  botanical  collections  on  board  the 
"  Terror,"  formed  a  most  important  herbarium,  from  which  great  assistance  has  been 
derived,  amounting  to  no  less  than  1 500  species.

I.    LORD  AUCKLAND'S  GROUP  AND  CAMPBELL'S  ISLAND. 

Under  this  head  will  be  considered  the  Botany  of  the  few  small  islands  which  lie  to 
the  south  of  New  Zealand,  at  least  so  far  as  have  hitherto  been  examined.  Of  these, 
the  two  most  important,  Lord  Auckland's  group,  in  50|°  S.  lat,  166°  E.  long.,  and 
Campbell's  Island,  lat.  52±°  S.  and  long.  169°  E.,  were  visited  by  the  "Erebus  and 
Terror,"  and  the  former  also  by  the  French  and  American  Discovery  Ships*. 

Upon  McQuarrie's  Island,  lat.  55°  S.,  long.  159°  E.,  a  very  few  plants  have  been 
collected,  which  are  deposited  in  the  herbarium  of  Mr.  Brown,  and  some  in  that  of  Sir 
William  Hooker,  at  Kew.  I  am  not  aware  that  any  account  has  been  published  of  these 
islands,  nor  of  Emerald  Island  (lat.  57°  S.,  long.  163°  E.),  the  botany  of  which  is  en- 
tirely unknown,  but  which  probably  in  this  meridian  constitutes  the  southern  extreme  of 
terrestrial  vegetation.  Floating  masses  of  Macrocyslis  and  D'Urvilltea  are  found,  how- 
ever, living  and  growing  on  the  limits  of  the  pack-ice,  as  far  as  the  parallel  of  64°  S. 

The  Flora  of  these  islands  is  closely  related  to  that  of  New  Zealand,  and  does 
not  partake  in  any  of  those  features  which  characterize  Australian  vegetation.  Most 
of  the  plants  may  indeed  be  presumed  to  exist  on  the  unexplored  mountains,  especially 
those  of  the  middle  and  southern  islands,  of  New  Zealand  ;  but  others  are  doubtless 
peculiar  to  those  higher  southern  latitudes  which  they  inhabit,  thus  being  analogous  to 

*  A  few  of  the  plants  collected  by  the  French  have  been  published  by  two  of  the  officers  of  Admira' 
D'Urville's  Expedition,  under  the  title  of  '  Voyage  au  Pole  Sud,  Botanique.'

those  few  novel  forms  that  appear  only  in  the  most  arctic  parts  of  America.  Even 
between  the  floras  of  Lord  Auckland's  and  Campbell's  Islands  a  marked  difference 
exists,  several  species  growing  most  abundantly  in  the  latter  which  are  not  found  at  all 
in  the  former,  where  also  the  proportion  of  species  common  to  other  Antarctic  coun- 
tries is  less,  and  the  affinity  is  greater  with  the  productions  of  New  Zealand. 

Lord  Auckland's  Group. — A  view  of  this  small  and  very  limited  group,  of  about 
twenty  miles  long  and  eleven  in  its  greatest  breadth,  as  it  appears  on  approaching  from 
the  sea,  presents  an  almost  equal  distribution  of  wood,  shrubs,  and  pasture-land.  The 
mountains  are  low  and  undulating,  nowhere  exceeding  1400  or  1500  feet,  clothed  for 
their  greater  part,  but  scarcely  to  the  very  summits,  with  long  grass,  and  frequently 
covered  during  November  and  December,  though  not  generally,  with  snow.  The 
climate  is  rainy  and  very  stormy,  so  that  on  the  windward  sides  the  plants  are  stunted 
and  checked,  and  resemble  those  of  a  higher  southern  latitude,  or  of  an  elevation  several 
hundred  feet  above  that  which  the  same  species  inhabit  on  the  sheltered  parts.  The 
whole  group  of  islands  appears  formed  of  volcanic  rocks,  mostly  of  black  trap,  whose 
decomposition,  especially  among  the  ranker  vegetation  of  the  lower  grounds,  produces 
a  deep  rich  soil.  A  Myrtaceous  tree  (Metrosideros  umbellata)  forms  the  larger  pro- 
portion of  the  wood  near  the  sea,  and  intermixed  with  it  grow  an  arborescent  species 
of  Dracophyllum,  several  Coprosmas,  Veronicas  (frutescent) ,  and  a  Panax.  Under  these, 
and  particularly  close  to  the  sea-beach,  many  Ferns  abound ;  conspicuous  among  them 
is  a  species  with  caulescent  or  subarborescent  stems  half  a  foot  and  upwards  in  diameter, 
crowned  with  handsome  spreading  tufts  of  fronds.  Beyond  the  wooded  region,  some 
of  the  same  plants,  in  a  dwarf  state,  mingled  with  others,  compose  a  shrubby  broad 
belt,  which  ascends  the  hill  to  an  elevation  of  800  or  900  feet,  gradually  opening  out 
into  grassy  slopes,  and  succeeded  by  the  alpine  vegetation.  It  is  especially  towards 
the  summits  of  these  hills  that  the  most  striking  plants  are  found,  vying  in  brightness 
of  colour  with  the  Arctic  Flora,  and  unrivalled  in  beauty  by  those  of  any  other  Antarctic 
country.  Such  are  the  species  of  Gentian,  and  a  Veronica  with  flowers  of  the  intensest 
blue,  several  magnificent  Composite,  a  Ranunculus,  a  Phyllachne,  and  a  Liliaceous  plant 
whose  dense  spikes  of  golden  flowers  are  often  so  abundant  as  to  attract  the  eye  from  a 
considerable  distance.  Here  too  the  vegetable  types  of  other  Antarctic  lands  may  be 
seen  in  the  greatest  number,  and  even  such  as  are  analogous  to  the  Arctic  productions, 
none  of  which  can  be  more  decided  than  a  species  of  Hierochloe,  Potentilla,  Cardamine, 
Juncus,  Drosera,  Plantago,  Epilobium,  several  Grasses,  and  Mosses  belonging  to  the 
genera  Andraa,  Conostomum  and  Bartramia.  Many  of  the  plants  in  the  lower  grounds 
are  no  less  striking  and  beautiful,  as  an  arborescent  Veronica  bearing  a  profusion  of 
white  blossoms,  a  maritime  Gentian,  a  handsome  large-flowered  Myosotis,  the  magnifi- 
cent Aralia  polaris  (Hombr.  and  Jacq.),  two  fine  kinds  of  Anisotome,  and  several  beau- 
tiful Ferns. 


Campbell's  Islands.]  FLORA  ANTARCTICA.  3 

Campbell's  Island,  two  degrees  to  the  southward  of  Lord  Auckland's  group,  is 
smaller,  far  more  steep  and  rocky,  with  narrow  sheltered  valleys,  and  the  broader  faces 
of  the  hills  much  exposed,  and  hence  bare  of  any  but  a  grassy  vegetation.  Except  in 
the  bays,  the  coast  is  as  iron-bound  as  that  of  St.  Helena,  the  rocks  assuming  even  a 
wilder  and  more  fantastic  form.  Ever  lashed  by  heavy  swells,  and  exposed  to  a  suc- 
cession of  westerly  gales,  this  land  affords  no  holding-place  for  such  trees  as  skirt  the 
beaches  of  Lord  Auckland's  Islands.  In  the  narrow,  sinuous  bays,  however,  the  scene 
is  quite  changed,  for  they  are  often  margined  by  a  slender  belt  of  brushwood,  with  an 
abundant  undergrowth  of  Ferns,  stretching  up  the  steep  and  confined  guileys. 

The  geological  features  of  the  two  islands  are  alike,  and  the  only  difference  in  cli- 
mate consists  in  that  of  Campbell's  Island  being  still  more  forbidding  and  dreary.  Fogs, 
snow-squalls  and  mists  are  the  prevailing  meteorological  phenomena  of  these  regions, 
and  though  such  a  state  of  atmosphere  has  a  tendency  to  check  the  general  mass  of 
vegetation,  still  the  constant  moisture  and  equable  temperature  thus  afforded  support 
a  luxuriant  herbage  in  the  very  sheltered  valleys.  In  Campbell's  Island,  the  mountains, 
which  rise  very  abruptly  to  about  1300  feet,  are  almost  bare  of  vegetation,  their  rocky 
sides  presenting  a  larger  proportion  of  Grasses,  Mosses  and  Lichens  than  in  Lord  Auck- 
land's group.  Though  all  the  handsomer  plants  are  also  found  in  the  larger  of  the 
latter  islands,  yet,  by  growing  here  at  a  much  lower  elevation  and  in  far  greater  abun- 
dance, they  form  a  more  striking  feature  in  the  landscape,  the  golden-flowered  Liliaceous 
plant  being  conspicuous,  from  its  profusion,  at  the  distance  of  a  mile  from  the  shore.

A  very  handsome  species,  and  quite  distinct  from  any  with  which  I  am  acquainted.  It  possesses,  however, 
several  of  the  peculiarities  of  other  Ranunculi  from  the  mountains  of  South  America  and  the  high  southern 
latitudes,  particularly  in  the  variable  form  and  number  of  the  petals.  In  its  succulent  habit  and  undivided 
leaves  it  has  an  affinity  with  R.  Cymbalaria,  but  is  perhaps  most  nearly  allied  to  R.  nivicola  (Hook.  Ic.  PI. 
t.  571-2) ;  especially  as  in  one  of  our  specimens  the  scape  is  bifid,  2-flowered,  and  bearing  a  large  cauline  leaf, 
thus  showing  a  disposition  in  the  plant  to  become  caulescent.  In  the  less  divided  foliage,  shape  of  the  petals, 
&c,  it  widely  differs  from  that  species,  and  more  particularly  in  the  curious  nectaries  which  are  only  observable 
in  the  var.  /3,  becoming  evanescent  in  the  larger  and  common  state  of  the  plant.  Here  they  are  large,  and 
situated  each  about  the  middle  of  one  of  the  three  principal  nerves,  which  seems  to  branch  into  three,  the  mid- 
dle branch  being  continued  through  the  nectary,  while  the  lateral  ones  are  thickened  and  run  round  its  edge, 
all  three  uniting  again  at  its  summit.  This  circumstance  may  however  be  only  caused  by  the  thickened  margin 
of  the  fovea,  as  the  nerves  do  not  appear  branched  in  the  petals  of  a,  nor  in  those  of  intermediate  states,  where 
the  nectaries  are  only  perceptible  as  opake  spots.  These  singular  nectaries  are  also  common  to  another  scapi- 
gerous  single-flowered  species,  the  R.  Gunnianus  of  Tasmania  (Hook.  Journ.  Bot.  vol.  i.  p.  244.  t.  133),  a  plant 
which  has  also  compressed  or  2-winged  styles.

These  specimens  entirely  agree  with  others  gathered  in  the  Bay  of  Islands,  New  Zealand  :  the  plant  ap- 
parently prefers,  and  is  perhaps  confined  to,  the  immediate  neighbourhood  of  the  sea,  and  in  this  meridian  has 
a  range  of  16  degrees  of  latitude  at  the  level  of  the  ocean.  The  only  species  to  which  it  has  any  affinity  is  the 
R.stenopetalus,  Hook.  (Ic.  Plant,  t.  677),  from  Chili,  to  which  it  is  very  nearly  allied;  the  difference  in  the 
comparative  breadth  of  the  petals  being  almost  the  only  one  I  have  been  able  to  detect.  The  situation  of  the 
nectary  on  the  petals  near  their  middle  is  common  to  a  large  proportion  of  the  species  of  this  genus  in  the

southern  hemisphere,  but  very  rare  in  those  of  the  northern;  the  R.parvifiorus  being  perhaps  the  only  British 
one  in  which  it  is  inserted  at  a  considerable  distance  from  their  base.  The  foliage  of  this  plant  is  sufficiently 
accurately  described  by  DeCandolle  from  Sir  Joseph  Banks's  New  Zealand  specimens,  but  the  corolla  requires 
some  correction,  and  the  fruit  was  unknown  to  that  author.  The  calyx  consists  of  from  3-5  membranous, 
very  concave,  deciduous  sepals.  Petals  narrow,  variable  in  number,  about  twice  as  long  as  the  sepals,  bright 
yellow,  li  line  long,  spreading  and  horizontal  in  the  expanded  flower  during  the  day,  3-nerved  ;  nectary  con- 
spicuous, sunk,  and  covered  with  a  closely  appressed  scale,  forming  together  a  deep  fovea,  opening  upwards, 
placed  on  the  middle  of  the  petal  and  resembling  the  fructification  of  some  Davallia.  Filaments  short,  linear- 
subulate.  Anthers  broadly  oblong.  Ovaries  about  15,  some  abortive,  gibbous  at  the  base,  with  a  curved  fal- 
cate style.  Carpels  forming  globose  heads,  few  in  number,  5-8  or  10,  rather  large,  compressed,  especially 
towards  the  axis  of  the  receptacle  ;  the  style  straight  or  curved,  very  short  or  longer  and  subulate.

This  plant  I  never  saw  growing ;  it  was  detected  by  my  friend  Mr.  Lyall.  In  general  appearance  it  very 
closely  resembles  the  R.  lappaceus,  Sm.,  of  Tasmania  and  the  northern  parts  of  New  Zealand,  a  species  which 
varies  much  in  size,  in  the  form  of  the  leaves,  and  in  the  nature  of  the  pubescence.  The  R.  subscaposus  is  more 
slender  in  habit,  with  the  hairs  always  closely  appressed  and  of  a  tawny  yellow  colour  ;  but  the  most  important 
distinction  lies  in  the  form  and  size  of  the  petals,  which  in  R.  lappaceus  are  much  larger  than  the  calyx  and  very 
broadly  obovato-cuneate,  with  a  large  triangular  fleshy  nectary  at  the  very  base;  but  in  this  plant  they  are

middle.     The  petioles  are  nearly  a  span  long;   the  leaves  about  an  inch  in  length  and  somewhat  more  in  width.

Hab.  Campbell's  Island ;  very  common  on  grassy  banks  from  the  sea  to  an  altitude  of  500  feet. 

Abundantly  gathered  and  used  as  a  salad  by  the  officers  of  the  ships,  its  succulent  leaves  being  an  excel- 
lent antiscorbutic.  A  very  dwarf  hairy  state  of  this  is  common  among  the  rocks  close  to  the  sea,  having  the 
flowers  always  purple.  Except  in  the  very  fleshy  leaves,  and,  occasionally,  coloured  petals,  this  is  in  no  way  to 
be  distinguished  from  the  ordinary  states  of  C.  hirsuta,  and  especially  from  Cape  Horn  and  Falkland  Island  spe- 
cimens, in  which  the  style  and  stigmata  are  variable  both  in  length  and  breadth  ;  in  the  large  size  of  the  petals 
it  agrees  with  Icelandic  and  other  hyperborean  specimens.  My  friend  Mr.  H.  C.  Watson  agrees  with  me  in 
considering  that  no  specific  difference  exists  between  this  plant  and  our  English  C.  hirsuta,  though  they  grow 
nearly  at  the  antipodes  of  each  other.     Of  the  stigmas  in  the  European  form,  he  observes,  "  they  are  broader

than  the  pods  when  in  an  early  stage,  but  as  the  latter  approach  maturity,  the  stigmas  shrink  and  dry.     This 
change  is  not  uniform  in  all  English  specimens."

This  is  a  small  and  very  distinct  species  of  Cardamine,  wiry  and  fragile  in  every  part.  The  stems  are  short, 
or  rather,  at  once,  after  springing  from  the  collum,  divided  into  spreading,  ascending,  filiform  branches,  with 
few  and  small  leaves  ;  and  with  corymbs,  or  more  correctly  speaking,  fascicles  of  flowers,  which  at  no  period 
seem  to  constitute  a  raceme.  Sometimes  even  the  flower  is  solitary  and  axillary ;  generally  several  spring 
together  from  the  side  or  apex  of  a  stem,  subtended  by  a  leaf;  sometimes  a  pedicel  appears  proliferous,  running 
out  into  a  stem  and  bearing  a  fascicle  or  corymb  and  a  leaf  at  its  apex  :  so  that  the  inflorescence  has  little  the 
appearance  of  that  of  a  cruciferous  plant.

A  very  distinct  species,  which  will  come  under  the  small  section  with  undivided  leaves,  to  which  also  the 
C.  bel/idifolia,  L.,  of  Northern  Europe,  belongs ;  a  plant  to  which  the  present  is  unquestionably  nearly  allied. 
In  both  these  species  the  leaves  vary  much,  being  sometimes,  but  rarely,  almost  entire  in  this,  whilst  in  the  C. 
bellidifolia  they  are  more  seldom  sinuate  or  lobed.  The  very  great  breadth  of  the  septum,  which  is  winged  on 
both  sides,  and  forms  an  acute  angle  with  the  valves,  is  a  most  remarkable  character,  peculiar,  as  far  as  I  am 
aware,  to  this  and  the  following  species  ;  at  times  it  is  almost  as  broad  as  the  valves  themselves.  In  South 
America  this  form  is  represented  by  C.  chenopodiifolia,  Pers.,  which  is  however  a  larger  and  caulescent  plant, 
with  very  conspicuous  showy  flowers, — a  similar  species,  or  perhaps  variety,  inhabits  the  Andes  of  Chili,  at  an 
elevation  of  10,000  feet.  The  var.  /3  was  gathered  in  a  very  imperfect  state  with  young  flowers  only.  In 
general  appearance  it  differs  much  from  the  normal  form  of  the  plant,  and  more  especially  in  the  flaccid  mem- 
branous texture,  long  petioles,  with  shorter,  rather  broader,  and  nearly  or  quite  entire  leaves.  It  may  prove 
distinct,  but  the  specimens  are  not  in  a  fit  state  for  satisfactory  determination.

The  habitat  of  this  plant  is  remarkable,  as  it  grows  only  in  the  most  exposed  situations  on  the  weather 
shores,  about  100  feet  above  the  sea.  In  the  form  of  the  leaves  it  resembles  the  C.  pusilla,  Hochst.,  an  Abys- 
sinian species,  but  these  are  here  more  crowded  and  spathulate,  and  the  inflorescence  is  quite  different.  The 
siliqua,  though  shorter,  has  very  much  the  same  form  as  that  of  C.  depressa.

In  many  respects  this  agrees  with  the  S.  uliginosa,  Murr.,  and  more  particularly  in  the  size  and 
arrangement  of  the  inflorescence,  but  the  stems  are  always  decumbent,  the  leaves  all  petiolate,  very  patent  or 
recurved,  and  not  at  all  broader  or  ovate  at  the  base  ;  their  callous  apices  are  common  to  both  species.  The 
peduncles  generally  bear  two  pedicels,  which  have  a  pair  of  bracts  at  the  base,  and  a  pair  on  one  of  the  pedi- 
cels, whereas  in  S.  uliginosa  the  peduncle  is  trichotomously  divided,  with  the  intermediate  pedicel  only  desti- 
tute of  bracts.  The  styles  seem  to  be  constantly  three,  and  the  stamens  and  petals  are  less  decidedly  perigy- 
nous  than  in  the  latter  plant.  In  form  the  leaves  resemble  those  of  S.  media,  With.,  but  the  inflorescence  is 
very  different,  and  the  stem  wants  the  alternate  line  of  hairs.

I  reo-ret  that  owing  to  the  early  season  I  only  met  with  two  or  three  flowers  of  this  rare  plant,  and  not  one 
specimen  with  perfect  fruit.  It  is  the  smallest  species  known  to  me,  and  has  a  creeping,  woody,  subfusiform, 
oblique  root,  throwing  out  coarse  fibres  ;  and  from  the  summits  of  this  spring  most  of  the  leaves.  The  stems,  or 
rather  scapes  (for  they  remain  withered  stalks  after  the  fall  of  the  fruit),  arise  also  from  the  top  of  this  root,  and 
are  branched,  twice  or  thrice  as  long  as  the  radical  leaves  :  they  bear  a  few  flowers  with  white  petals,  which 
are  succeeded  by  the  narrow  elongated  receptacle,  hispid  as  it  were  with  the  persistent  stipites  of  the  carpels. 
It  is  this  character  which  it  has  in  common  with  a  very  arctic  species,  the  S.  Rossii,  Br.,  together  with  the 
very  short  styles,  that  induces  me  to  place  it  in  Sieversia  ;  for  the  style  seems  too  short  ever  to  be  geniculated. 
It  further  differs  from  all  known  species  in  having  white  petals.

membranous,  obovate  or  cuneate,  ^—|  inch  long,  coarsely  inciso-serrate,  glabrous  on  the  upper  surface,  pubes- 
cent or  almost  silky  beneath.  The  scapes  or  peduncles,  bearing  the  globose  capitula,  are  quite  glabrous.  The 
whole  plant  varies  much  in  the  size  and  toothing  of  its  leaflets,  whence  I  am  inclined  to  think  it  may 
be  the  large  and  ordinary  form  of  A.  Magellanica,  Lam.  ;  although  Vahl  describes  the  peduncles  of  that  plant 
as  "  superne  subvillosi."  I  further  doubt  how  far  the  A.  ovdlifolia,  Ruiz,  and  Pav.  (Fl.  Per.  t.  103.  f.  c),  will 
prove  distinct ;  it  again  is  allied  to  the  A.  Sanguisorbce,  Vahl.  The  present  form  was  not  found  either  in  Tas- 
mania, New  Zealand,  or  in  Lord  Auckland's  or  Campbell's  Islands.  The  fact  of  its  reappearance  in  a  higher 
southern  latitude  is  an  interesting  one,  and  in  accordance  with  the  known  laws  affecting  the  distribution  of 
plants.

A  very  pretty  species,  allied  to  the  E.  nummular  {folium,  R.  Cunn.,  of  New  Zealand,  but  readily  distin- 
guished by  its  much  larger  size  and  thin,  flaccid  (not  fleshy)  leaves,  which  are  strongly  eroso-dentate.  In  Mr. 
Colenso's  specimens  the  stems  are  longer,  and  the  leaves  less  rounded  in  form  with  longer  petioles.  Stems 
weak,  terete,  3-6  inches  long.  Leaves  in  rather  remote  pairs,  bright  green  and  shining  above,  often  discoloured 
and  purplish  beneath,  ^—§  inch  long,  sometimes  broader  than  long.  Petioles  1-3  lines.  Peduncles,  even  when 
flowering,  very  variable  in  length,  from  ~-3  inches  long,  generally  erect.  Sepals  concave,  especially  towards 
the  apex,  which  is  produced  into  a  thickened,  short,  club-shaped  apiculus  or  gland.  Petals  about  half  as  long 
again  as  the  sepals,  1|  lin.  long,  of  a  pale  rose-colour,  bifid  nearly  half-way  down.  Filaments  thickened  at  the 
connectivum.  Style  gradually  swelling  upwards  into  a  club-shaped  obtuse  stigma.  Capsule  (which  I  have 
seen  ripe  only  in  the  New  Zealand  specimens)  narrow,  erect,  quite  glabrous,  about  an  inch  long.

This  little  plant  in  every  respect  occupies  the  place  in  these  islands,  that  the  E.  alpinum,  L.,  does  on  the 
European  mountains.  The  two  species  are  indeed  so  very  closely  allied,  that  I  look  in  vain  for  further  constant 
characters  than  the  creeping  and  rooting  much-branched  stem,  the  densely  crowded,  broader,  and  more  obovate 
leaves  with  almost  sheathing  petioles,  and  the  deeply  bifid  petals  of  the  present  one.  The  more  remarkable 
points  of  similarity,  besides  the  general  appearance,  are  the  lines  of  pubescence  on  the  stem,  the  sessile  or 
shortly  pedunculated  ovaria  (which  in  E.  alpinum  are  however  often  lengthened),  the  deep  colour  of  the  petals, 
and  the  simple  clavate  stigma,  which  is  here  decidedly  oblique  and  gibbous  at  the  base.  A  very  similar  species 
is  found  on  the  Andes  of  Peru  and  in  Chili.

Hab.  Lord  Auckland's  group ;  in  moist  rocky  places,  alt.  1200  feet,  rare,  not  found  in  flower

In  these  very  imperfect  specimens  the  leaves  are  much  more  fleshy,  and  their  margins  more  strongly  re- 
curved, than  in  others  gathered  by  Mr.  Menzies  in  Dusky  Bay,  or  by  myself  in  the  Bay  of  Islands.  Like  other 
species  however  of  the  same  genus,  the  plant  is  probably  a  very  variable  one.  Mr.  Cunningham  quotes  the  E. 
pendulum,  Sol.,  as  a  synonym  of  E.  nummular  if olium,  R.  Cunn.,  a  species  very  nearly  allied  to  the  present,  but 
larger,  with  distinctly  crenate  leaves,  and  having  the  capsules  hoary  with  a  white  down.  In  habit  and  foliage 
this  plant  resembles  the  Anagallis  tenella,  L.,  and  as  well  as  many  of  the  New  Zealand  species,  it  has  a  pecu- 
liarly creeping  mode  of  growth,  which  none  of  those  of  the  northern  hemisphere  possess.

A  very  general  plant  throughout  the  Antarctic  Islands  visited  by  the  "  Erebus  and  Terror."  First  noticed  as 
a  native  of  the  Falkland  Islands  by  Admiral  D'Urville,  who,  in  his  description  of  the  plant,  which  is  not  uncom- 
mon there,  and  is  identical  with  the  var.  /3.  of  Campbell's  Island,  alludes  to  the  filament  and  ovarium  as  each 
arising  from  a  minute  bipartite  calyx.  Neither  in  my  dried  specimens,  nor  when  in  a  fresh  state,  could  I  detect 
organs  answering  to  this  description.  The  bracteas,  which  are  extremely  caducous,  and  only  exist  in  the  very 
youngest  state  of  the  flower,  are  singularly  falcate,  linear-subulate  and  membranaceous,  similar  to  those  of  C. 
platycarpa,  Kiitzing.     The  leaves  vary  much  in  shape,  and  the  whole  plant  in  size,  as  in  Europe.     The  anthers,

(though  described  as  one-celled)  are  in  reality  didyrnous  and  2-celled ;  they  first  open  down  each  side  and  then 
across  the  connectivum  at  the  top,  always  remaining  partially  2-celled.  Filaments  often  very  long,  half  an  inch 
and  upwards.  The  styles  are  also  slender,  and  when  highly  magnified  exhibit  throughout  their  length  minute

Hab.  Lord  Auckland's  group  ;  from  the  sea  to  an  altitude  of  500  feet.  Abundant.  (Not  seen 
in  Campbell's  Island.) 

Originally  discovered  by  Sir  J.  Banks  and  Dr.  Solander  at  Totarra  nui  in  the  North  Island  of  New  Zea- 
land, and  a  very  fine  drawing  of  it,  made  during  Captain  Cook's  first  voyage,  is  preserved  in  the  British  Mu- 
seum. It  was  again  found  by  Forster  during  Cook's  second  voyage,  in  Dusky  Bay,  and  by  him  first  published. 
Mr.  Menzies  also  gathered  it  at  the  latter  locality.  I  am  at  a  loss  to  conceive  how  the  specimens  came  into 
the  possession  of  Felix  Nee,  from  whose  collection  Cavanilles  figured  and  described  the  plant  under  the  name 
of  Metros,  umbellata,  as  a  native  of  Port  Jackson.  The  figure  given  by  the  latter  author  is  very  characteristic, 
except  that  the  peduncles  are  represented  as  too  long  and  slender.  In  the  plate  accompanying  the  late  French 
expedition  of  Admiral  D'Urville,  the  sketch  of  the  entire  plant  does  not  do  justice  to  that  which  constitutes  the 
largest  tree  on  Lord  Auckland's  group,  and  the  most  abundant,  skirting  the  whole  line  of  sea-coast  with  a  broad 
belt  of  evergreen  flat-topped  forest  wood.  The  single  trees  are  fiom  20-40  feet  high,  inclined,  with  trunks 
2-3  feet  in  diameter,  often  flattened,  seldom  erect,  covered  with  a  pale  reddish  bark,  which  flakes  off  like  that 
of  the  birch.  From  the  trunks  and  lower  branches  there  are  often  sent  out  large  tufts  of  dry  root-like  pro- 
cesses, which  run  along  the  surface,  and  are  covered  with  a  loose  thick  and  spongy  light  brown  cuticle.  The 
branches  are  spreading  and  ascending,  from  the  inclemency  of  the  climate  and  violence  of  the  winds  forming 
stag-headed  trees,  whose  tops  are  perfectly  flat,  as  if  cut  with  a  scythe.  The  ultimate  branches,  which  bear  a 
few  leaves,  are  angular  and  covered  with  a  loose  white  papery  cuticle,  which  turns  yellow  in  drying.  The  leaves 
are  of  a  lurid  but  shining  green,  more  yellow  on  the  under  surface,  and  there  covered  with  large  yellow  glands. 
Petals  when  young  white  with  red  tips,  in  the  more  expanded  state  crimson,  as  are  the  stamens.  The  inflores- 
cence in  this,  as  in  all  other  New  Zealand  species,  is  in  umbels  or  corymbs.  The  Myrtacete,  which  in  North 
America  do  not  attain  a  higher  latitude  than  26°,  and  in  Europe  only  one  reaches  the  46th  degree,  in  the  south- 
ern regions  are  amongst  the  most  Antarctic  plants,  being  most  abundant  in  Tasmania,  lat.  42-44°  S.  ;  in  New 
Zealand,  throughout  the  islands  as  far  as  50^°  S.,  and  in  South  America  accompanying  other  plants  as  far  as 
o6°  S.,  where  that  continent  terminates  in  the  South  Polar  Ocean.

Hab.  Lord  Auckland's  group  and  Campbell's  Islands;  in  moist  places  near  the  sea,  abundant. 

This  is  a  very  variable  plant  and  an  exceedingly  common  one  in  the  southern  regions.  The  specimens  from 
the  various  Antarctic  islands  vary  much  in  size,  in  the  form  of  the  leaf,  in  the  number  of  the  stamens,  and  in  the 
number  and  nature  of  the  surface  of  the  seeds.  Those  of  the  Auckland  and  Campbell's  Island  specimens  agree 
with  the  figure  quoted  of  Chamisso's  M.  lamprosperma,  but  they  are  not  larger  than  the  seeds  of  European  spe- 
cimens. The  Falkland  Islands,  form  again  has  the  seeds  very  large  with  a  black  tuberculated  shining  testa, 
agreeing  in  the  latter  character  with  those  of  Kerguelen's  Land,  which  are  however  smaller.  In  the  Peruvian 
plant  the  seeds  are  very  small,  but  covered  and  almost  echinate  with  crowded  elevated  linear  tubercles.  Those 
of  the  English  plant  are  not  constant  in  size,  but  the  testa  is  generally  more  opake  and  not  remarkably 
tuberculated.  It  is  difficult  to  find  a  more  widely  distributed  phrenogamic  plant  than  this,  especially  in  the 
southern  hemisphere,  where  it  generally  accompanies  the  Callitriche  verna.  In  New  Zealand  and  in  Peru  it 
inhabits  a  more  elevated  region.  According  to  Boissier,  it  attains  in  Spain  an  altitude  of  5000-7000  feet.  In 
the  Highlands  of  Scotland  it  ascends  to  3000  feet,  and  reaches  as  far  north  as  Iceland  and  Siberia  in  Europe 
and  Asia.  Though  universally  distributed  over  all  the  temperate  parts  of  these  two  continents,  and  in  the  south, 
it  appears  to  be  singularly  rare  in  North  America,  being  hitherto  detected  only  in  Labrador,  Greenland  (whose 
Flora  presents  more  European  peculiarities  than  any  other  part  of  America  east  of  the  Rocky  Mountains),  Sitka 
and  the  Oregon.

Of  rare  occurrence,  and  confined  to  the  tops  of  the  hills  in  Campbell's  Island  ;  nowhere  seen  in  Lord  Auck-

both  on  the  low  grounds  and  on  the  mountains.  I  have  followed  Fenzl  and  Endlicher  in  placing  this  genus  in 
Portulacea,  though  I  must  confess  that  to  me  it  appears  too  closely  allied  to  Caryopliyllea,  and  especially

to  Sagina,  to  be  far  removed  from  that  genus,  while  the  habit  is  not  that  of  an)'  of  this  Order.  The  present 
plant  differs  from  its  congeners  in  being  rigid  and  somewhat  pungent ;  the  structure  of  the  flower  however 
entirely  agrees  with  that  of  the  previously  described  species.  All  the  specimens  I  have  examined  from  this 
locality  have  a  5-sepalous  perianth,  which  in  the  South  American  state  of  the  plant  is  as  invariably  4-sepalous. 
It  is  also  apt  to  assume  here  a  monstrous  state,  the  central  axis  of  the  capsule  becoming  proliferous  and  sending 
out  from  the  position  of  the  placenta;  (in  the  natural  state)  two  foliaceous  shoots,  each  with  two  pairs  of  leaves, 
projecting  beyond  the  perianth,  and  the  ovules  (abortive)  arranged  round  the  bases  of  these  shoots.

most  nearly  allied  to  the  finest  of  the  genus,  a  Kerguelen's  Land  species.  The  whole  plant  is  densely  matted 
and  fleshy,  forming  compact  tufts.  Stems  3-4  inches  long.  Leaves  2  lines.  The  flowers  are  much  compressed, 
very  minute  and  inconspicuous,  1  line  long,  sunk  among  the  leaves.  Perianth  of  four  erect  sepals,  of  which  the 
lateral  are  larger,  more  concave,  and  keeled  at  the  back.  Perigynous  ring  very  conspicuous,  and  swollen  into 
two  large  yellow  fleshy  glands  between  the  bases  of  the  stamens.

This  species  was  originally  discovered  by  Banks  and  Solander  at  Totarra  nui,  in  the  Northern  Island  of 
New  Zealand,  during  Captain  Cook's  first  voyage,  and  an  excellent  drawing  of  it,  by  Parkinson,  is  preserved  in 
the  Banksian  collection.  Labillardiere  afterwards  detected  it  in  Tasmania,  whence  Mr.  Gunn  sent  beautiful 
specimens,  in  describing  which  I  had  occasion  to  notice  its  near  affinity  with  the  genus  Sagina.  Fenzl  (/.  c. 
according  to  Walper's  Repert.  vol.  ii.  p.  249)  quotes  the  Sagina  crassifolia,  D'Urv.,  as  a  synonym  of  his  C.  Bil- 
lardieri, and  reduces  the  original  plant  of  Labillardiere  to  a  variety,  under  the  name  of  ft.  procerior.  What  I 
take  for  the  plant  of  Admiral  D'Urville,  whose  description  (Mem.  Soc.  Linn.  Paris,  vol.  iv.  p.  617)  is  very  charac- 
teristic, is  much  larger,  of  a  different  habit,  and  with  truly  linear  very  fleshy  leaves,  and  is  common  in  the  Falk- 
lands,  as  well  as  the  C.  Quitensis,  Bartl.,  which  is  closely  allied  to  the  C.  affinis  (Spergula  affinis,  Hook.  Icon. 
Plant,  vol.  iii.  t.  26b').  Labillardiere  says  of  the  stamens  of  C.  Billardieri,  "  sub  pistillo  inserta,"  but  this  is  not 
the  case  with  the  specimens  I  have  examined.  They  are  clearly  placed  at  the  exterior  of  a  membranous  disc 
which  surrounds  the  perianth,  remote  from  the  base  of  the  ovary.  The  Campbell's  Island  specimens  are  very 
small,  scarcely  an  inch  high,  whereas  the  Tasmanian  are  twice  or  thrice  that  size.

A  decidedly  extra-tropical  South  American  form,  belonging  to  a  section  of  the  Nat.  Ord.  hitherto  un- 
known to  the  Floras  both  of  New  Zealand  and  Australia.  The  remarkable  similarity  of  the  flower  and  fruit  to 
those  of  the  P.  coriacea,  Lag.  (Hook.  Bot.  Misc.  vol.  i.  p.  331.  t.  66),  together  with  the  uniformity  in  the  struc- 
ture of  its  calyx  and  petals  with  that  plant,  have  induced  me  to  refer  it  to  the  same  genus ;  but,  from  the 
difference  in  habit  and  the  structure  of  the  involucre  of  the  species  thus  brought  together,  I  have  ventured  to 
place  this  in  a  separate  subgenus.  The  original  species  (P.  coriacea),  and  the  P.  hydrocotylifolia,  Bridges  and 
Fielding  (Sertum  Plant,  t.  40),  have  the  flowers  monoecious,  a  character  I  do  not  observe  in  this.  The  simila- 
rity which  the  present  plant  bears  to  the  genus  Azorella,  Gaud.,  is  in  many  respects  close  ;  the  mericarps  of  this 
are  hardly  "  parallelim  biscutata,"  whilst  those  of  Azorella  are  scarcely  didymous.  Though  a  very  remarkable 
habit  runs  through  most  of  the  species  of  the  latter  genus,  one  of  them,  the  A.  Ranunculus,  D'Urv.,  not  only 
differs  from  its  congeners  in  form  and  mode  of  growth,  but  in  these  respects  much  resembles  this  plant.     In  the 


16  FLORA  ANTARCTICA.  [Auckland  and 

structure  of  the  flower  and  fruit  the}'  totally  differ,  the  former  being  truly  an  Azorella,  and  having  the  ciliated 
involucral  leaves  common  to  other  species  of  that  genus.  The  Az.  daucoides,  D'Urv.  Fl.  Ins.  Mai.  1.  c.  p.  613, 
is  probably  a  true  Caldasia,  Lag.

Hab.  Lord  Auckland's  group  and  Campbell's  Island  ;  in  moist  places  from  the  sea  to  the  tops 
of  the  mountains,  abundant. 

This  is  certainty  one  of  the  noblest  plants  of  the  natural  order  to  which  it  belongs,  often  attaining  a 
height  of  six  feet,  and  bearing  several  umbels  of  rose-coloured  or  purplish  flowers,  each  compound  umbel  as 
large  as  the  human  head.     The  foliage  is  of  a  deep  shining  green,  and  the  whole  plant  emits,  when  bruised,  an 
aromatic  smell.     The  female  flowers  I  have  only  seen  in  a  specimen  gathered  by  Mr.  Lyall  in  Campbell's  Island. 
They  are  of  a  peculiar  structure,  and  show  a  striking  affinity  between  this  plant  and  the  Aciphylla  squarrosa, 
Forst.  (Hook.  Icon.  PI.  vol.  vii.  t.  G07,  608),  especially  in  the  unequal  mericarps.     Both  the  male  and  female  flow- 
ers vary  in  the  size  of  the  calycine  segments,  which  are  however  constantly  unequal,  one  or  more  being  much 
the  largest  and  longest.     In  the  male  the  styles  are  reduced  to  mere  points  on  the  inner  margin  of  the  depressed 
purple  stylopodia ;  in  the  female  the  latter  organs  are  conical,  and  terminate  in  long  stout  recurved  styles,  ca- 
pitate at  the  extremity  :  this  structure  is  common  to  Aciphylla,  according  to  Forster's  figure  (Genera,  t.  6S).     In 
the  description  of  the  genus  I  have  described  what  may  be  considered  the  normal  form  of  the  fruit,  but  it  is  liable 
to  much  variation,  and  the  five  ridges  are  seldom  fully  developed  in  both  mericarps.     The  five  lobes  of  the  calyx 
always  give  origin  to  as  many  larger  ridges,  and  these  again  vary  in  size  according  to  the  number  of  large 
lobes  :  the  most  fully  developed  segment  of  the  calyx,  whether  lateral  or  dorsal  on  the  mericarp,  always  being 
opposite  to  the  larger  ridge.     Very  generally  there  are  three  large  lobes  to  the  calyx  (of  the  female  flower),  one 
near  the  back  of  one  mericarp,  and  two  lateral  on  the  other  ;  that  with  three  has  then  five  ridges,  two  large  lateral, 
one  (also  large  dorsal),  and  two  intermediate  smaller  :  the  mericarp  with  only  one  large  lobe  has  only  four  ridges  ; 
two  lateral  (one  of  which  is  from  the  small  lobe  and  largest  of  these  two),  the  other  very  large,  from  the  larger 
tooth.     These  mericarps  are  about  two  lines  long,  of  a  fuscous  yellow  colour,  are  obscurely  glandular,  and  the

vitta;  extend  through  their  whole  length.  The  seed  hangs  loose  in  the  cell,  is  small,  and  covered  with  a  rather 
thick  blackish  testa ;  its  sides  have  furrows  corresponding  to  the  valleculas.

Hab.  Lord  Auckland's  group  and  Campbell's  Island;  in  moist  places  especially  near  the  sea, 
and  in  the  former  islands  ascending  to  the  mountain  tops  in  a  more  stunted  form. 

A  scarcely  less  handsome  plant  than  the  former,  with  which  it  agrees  entirely  in  habit,  and  more  particu- 
larly in  the  structure  of  the  male  flowers.  The  umbels  are  however  less  densely  crowded,  borne  on  longer  pe- 
duncles, and  produce  fewer  partial  umbels  and  flowers.  I  was  unfortunate  in  not  being  able  to  detect  female 
flowers,  nor  have  I  seen  any  nearer  approach  to  that  state  of  the  plant  than  the  occasional  presence,  amongst 
the  flowers  of  the  ray,  of  stylopodia  and  styles  analogous  to  those  of  the  female  of  the  former  species.  The 
fruit  of  this  plant  is  represented  in  the  'Botany'  of  the  French  Voyage  of  Discovery  quoted  above,  but  in  it  the 
mericarps  are  figured  as  equal,  and  the  vitta?  are  probably  accidentally  omitted ;  so  very  singular  a  character  as 
the  former  may  have  been  overlooked  in  the  dry  state  of  the  plant ;  the  glands,  which  are  very  obscure  in  the 
former  species,  are  in  this  very  large  and  apparently  confined  to  one  side  of  each  mericarp  :  a  remarkable  simi- 
larity, however,  exists  in  the  furrowed  seeds  and  in  the  stylopodia  of  the  two  species.  The  lamellae  in  the  fistu- 
lar  portion  of  the  stem  are  not  represented,  and  the  sketch  of  the  entire  plant  bears  but  a  slight  resemblance 
to  the  state  in  which  we  drew  it. 

In  structure,  the  fructification  of  this  genus  is  more  closely  allied  to  Aciphyllu,  Forst.,  than  its  general  ap- 
pearance would  lead  one  to  suppose.  The  figure  of  that  plant  (in  the  Icones  Plant.)  was  taken  from  a  specimen 
in  fruit,  the  only  state  in  which  we  possessed  it  previous  to  the  arrival  of  Mr.  Stephenson's  New  Zealand  collec- 
tion (vide  Lond.  Journ.  of  Bot.  for  September  1844),  which  contains  small  portions  of  apparently  this  plant  (n.  81) 
in  flower.  In  it  the  partial  umbels  are  few-flowered,  with  the  peduncles  divaricating  ;  they  are  borne  on  axillary 
branches,  subtended  by  a  sheathing,  lanceolate,  acuminated,  pungent  involucral  leaf ;  towards  the  apex  of  the 
stem  these  branches  are  more  crowded,  and  the  involucral  leaves  are  lengthened  and  become  bifid  or  even  trifid. 
The  calycine  segments  are  very  small,  broad,  obtuse,  and  nearly  equal  in  size.  The  petals  (apparently  pale  yellow), 
though  more  incurved  than  in  Anisotome,  are  scarcely  furnished  with  an  "  inflexed  lacinula"  ;  the  stamens,  sty- 
lopodia and  styles  are  very  similar  in  the  two  genera.  The  female  flowers  are  probably  more  densely  aggre- 
gated than  the  male,  and  in  the  inflorescence  of  the  former  the  involucral  leaves  may  rapidly  assume  the  curious 
form  represented  in  the  '  Icones,'  or  Mr.  Stephenson's  specimens  may  belong  to  a  different  species,  for  certainly 
their  mode  of  inflorescence  bears  little  resemblance  to  the  dense  cylindrical  female  spike  of  the  A.  squarrosa. 
Both  these  genera  will  naturally  rank  near  Ligusticum,  from  which  they  are  however  very  distinct,  and  may  be 
considered  as  forming  a  small  natural  group.  What  I  am  inclined  to  consider  as  a  third  species  of  Anisotome 
is  the  Ligusticum  anisatum,  Banks  and  Sol.  MSS.  in  Mus.  Brit. ;  a  plant  discovered  by  Sir  J.  Banks  and  Dr. 
Solander  in  Queen  Charlotte's  Sound,  and  a  fourth  has  been  since  gathered  in  Cook's  Straits  by  Dr.  Dieffenbach, 
and  on  the  high  mountain  of  Tongariro  by  Mr.  Bidwill ;  both  these  gentlemen's  specimens  are  male.  The  An-

18  FLORA  ANTARCTICA.  [Auckland  and 

gelica  ?  roseefolia,  Hook.  Ic.  Plant,  t.  581  (Ligusticum  aromaticum,  Banks  and  Sol.  Ic.  in  Mus.  Brit.),  is  also  in 
some  measure  allied  to  these,  though  a  plant  of  a  very  different  habit ;  its  calycine  segments  are  decidedly  un- 
equal in  size,  and  one  of  the  two  mericarps  is  often  abortive. 

In  the  three  known  species  of  Anisotome,  all  the  parts  connected  with  the  inflorescence  are  subject  to  much 
irregular  metamorphosis  and  monstrous  development,  the  more  important  of  which,  as  observed  in  the  living 
plants  of  A.  latifolia  and  A.  antipoda,  are  the  following  : — 1st,  the  segments  of  the  partial  involucra  become 
shrivelled,  assuming  the  forms  of  peduncles,  and  bear  at  their  apices  stylopodia  with  distorted  calycine  seg- 
ments, or  more  perfect  flowers  with  a  reduced  number  of  parts ;  or,  in  one  case,  a  solitary  one-celled  anther, 
full  of  pollen,  adnate  on  the  face  of  the  leaf,  a  little  below  its  apex  :  2nd,  the  peduncles  themselves  of  the 
outer  flowers  become  foliaceous,  or  by  dividing  show  a  tendency  to  a  further  compound  state  of  the  umbel ; 
it  also  sometimes  bears  a  single  stamen  at  its  apex,  subtended  by  one  large  calycine  segment :  3rd,  the 
calycine  segments  vary  from  2-6,  but  one  or  more  are  always  so  much  larger  than  the  others,  as  often  to 
resemble  involucral  leaves  :  4th,  the  petals  are  wanting,  or  vary  from  1-6  ;  sometimes  two  are  combined  into 
one ;  at  others  they  assume  various  shapes  :  5th,  the  stamens  are  equally  variable  in  number  ;  the  filament  is 
at  times  petaloid,  or  becomes  forked  and  bears  a  second  anther  ;  these  are  constantly  perfect  and  full  of  pollen  : 
6th,  the  stylopodia  are  always  2  or  more,  often  3,  generally  of  the  plane  depressed  form  common  to  the  male 
flowers  ;  but  the  flowers  of  the  ray  sometimes  bear  2-4  of  entirely  a  different  form,  and  similar  to  those  of  the 
fertile  umbels  ;  these  are  sometimes  accompanied  with  stamens  : — generally  no  numerical  relation  can  be  traced 
between  the  parts  of  these  irregularly  developed  flowers.  That  such  a  relation  however  exists  is  demonstrable 
in  a  very  distorted  example,  where  a  flower  was  furnished  with  6  calycine  segments,  3  very  large  and  the 
others  very  small,  2  petals,  6  stamens,  one  of  which  bore  two  perfect  anthers,  and  2  stylopodia,  in  all  17  parts, 
the  normal  number  in  the  ordinary  state  of  the  plant.  Perhaps  the  most  complex  example  was  exhibited  in  one 
of  the  outer  pedicels  of  a  partial  umbel,  which  was  terminated  by  4  stylopodia  surrounded  by  a  5-toothed  calyx, 
the  latter  subtended  on  one  side  by  4  linear,  foliaceous,  very  imperfectly  developed  organs,  each  of  them  fur- 
nished at  its  apex  with  an  obscure  depression  filled  with  yellow  powder.  It  here  appears  to  me  that  the  appa- 
rent pedicel  is  the  peduncle  of  a  partial  umbel  bearing  one  sessile  female  flower,  and  that  the  three  superadded 
foliaceous  organs  represent  the  pedicels  of  male  flowers,  which  are  reduced  to  as  many  fovea?  containing  pollen, 
a  most  rudimentary  state  of  the  male  flower.  I  did  not  observe  whether  the  stylopodia  were  internal  or  exter- 
nal in  relation  to  the  axis  of  the  plant  and  the  three  supposed  male  pedicels  ;  probably  however  the  latter,  as  it 
is  the  flowers  of  the  ray  which  generally  bear  female  stylopodia.

islands  beyond  it.  As  far  as  I  am  aware,  it  had  been  previously  gathered  by  Forster  alone.  In  this  group  it 
attains  a  height  of  30  feet,  amongst  other  trees  near  the  sea.  Its  trunks  are  sometimes  2-3  feet  in  diameter, 
covered  with  a  smooth  brown  bark  ;  the  wood  is  white  and  close-grained.  Branches  much  scarred,  and  clothed 
with  a  pale  bark,  very  brittle.  The  distinct  joint  at  the  apex  of  the  petiole  indicates  the  truly  compound  nature 
of  the  leaves  ;  they  are  nowhere  described  as  ternate  ;  a  character  which  all  young  trees  of  this  species  exhibit. 
The  whole  plant  has  a  faint  but  rank  smell,  like  that  of  Ivy,  which  the  copious  lurid  green  but  shining  coria-

One  of  the  most  handsome  and  singular  of  the  vegetable  productions  in  the  group  of  islands  it  inhabits, 
which  certainly  contains  a  greater  proportion  of  large  and  beautiful  plants,  relatively  to  the  whole  vegetation,  than 
any  country  with  which  I  am  acquainted.  Growing  in  large  orbicular  masses,  on  rocks  and  banks  near  the 
sea,  or  amongst  the  dense  and  gloomy  vegetation  of  the  woods,  its  copious  bright  green  foliage  and  large  umbels 
of  waxy  flowers,  often  nearly  a  foot  in  diameter,  have  a  most  striking  appearance.  The  pretty  black  berries  on 
the  white  and  withered  stalks  of  the  former  year's  umbels  form  a  curious  contrast  to  the  shining  waxy  appear- 
ance of  the  rest  of  the  inflorescence.  The  whole  plant  has  a  heavy  and  rather  disagreeable  rank  smell,  common 
to  many  of  its  Nat.  Order,  but  is  nevertheless  greedily  eaten  by  goats,  pigs  and  rabbits. 

Beautiful  as  is  the  plate  of  Aralia  polaris  in  the  French  South  Polar  Voyage  above  quoted,  and  faithfully 
as  it  represents  the  leaf  and  umbel,  the  insertion  of  both  immediately  upon  the  rooting  stem,  without  the  in- 
tervention of  branches,  and  the  absence  of  the  great  ligules,  are  quite  unlike  what  is  exhibited  by  my  specimens. 
It  is  possible  that  the  letter-press  may  account  for  this  and  some  other  apparent  inaccuracies  ;  but  although  the 
plates  have  been  in  our  possession  for  nearly  a  twelvemonth,  I  cannot  learn  that  any  descriptive  matter  has 
hitherto  appeared. — The  above  particulars  of  the  plant,  and  the  analysis,  were  drawn  up  from  living  specimens  ; 
and  although  the  drawings,  made  at  the  same  time  from  the  recent  plant,  are  not  of  sufficient  novelty  to  justify 
their  introduction  amongst  the  plates  of  the  present  work,  I  have  deemed  it  desirable  to  give  them  in  the  '  Icones 
Plantarum'  (vol.  viii.  tab.  701.  ined.).

This  is  a  perfectly  distinct  plant,  though  confounded  by  Cunningham  (as  his  specimens  in  Herb.  Heward 
prove)  with  the  C.  lucida,  Forst.  It  is  probably  a  very  abundant  species  in  the  middle  and  southern  islands  of 
New  Zealand,  where,  however,  it  had  until  quite  lately  been  gathered  by  Forster  alone,  in  Queen  Charlotte's 
Sound.  It  has  been  more  recently  detected  on  the  mountainous  interior  of  the  Northern  Island  by  Mr.  Colenso, 
whose  specimens  (n.  117)  are  rather  less  robust,  with  the  leaves  narrower  and  more  membranaceous.  It  is  one 
of  the  few  large-leaved  species  with  truly  solitary  and  sessile  flowers  and  berries.  In  this  group  of  islands  it 
often  attains  a  height  of  20  feet,  with  a  trunk  1|  foot  in  diameter.  The  whole  plant,  especially  when  bruised 
or  when  drying,  exhales  an  exceedingly  fetid  odour,  much  resembling  that  of  the  flowers  of  Hibbertia  volubilis. 
I  brought  on  board  the  "  Erebus"  specimens  of  this  with  other  plants,  late  one  evening,  and  finding  that  there 
were  more  tender  species,  which  took  a  considerable  time  to  lay  in  paper,  than  I  could  well  get  through  that  night, 
I  locked  this  Coprosma  in  a  small  close  cabin  until  I  should  have  leisure  to  press  it,  but  before  half  an  hour  had 
elapsed  the  smell  was  intolerable,  and  had  pervaded  the  whole  of  the  lower  deck.  The  leaves,  though  very 
constant  in  form,  vary  much  in  size,  and  in  the  alpine  specimens  are  scarcely  more  than  ^-^  inch  long.

This  plant,  which  I  found  only  in  the  state  of  young  fruit,  is  so  nearly  allied  to  the  preceding,  that  it  is 
not  without  much  hesitation  I  retain  it  as  a  distinct  species,  which  I  do  on  the  ground  of  there  being,  in  a  large 
suite  of  specimens  of  C.fcetidissima,  none  with  the  leaves  intermediate  in  form  between  that  species  and  the  pre- 
sent. It  may  he  readily  recognised  by  the  larger  and  longer  leaves,  which  are  decidedly  acuminated  at  the  apex  : 
its  season  of  flowering  too  seems  to  be  different.

The  investigation  of  the  genus  Coprosma,  and  especially  of  the  small-leaved  species,  is  attended  with  very 
great  difficulty.  Those  of  the  extreme  southern  parts  of  the  New  Zealand  group  seem  different  from  such  as 
inhabit  the  northern  islands,  and  these  again  from  the  Australian  and  Tasmanian  kinds.  In  each  locality,  how- 
ever, the  forms  seem  so  protean,  that  more  than  words  is  required  to  assist  in  their  determination,  whilst  the 
paucity  of  specimens  hitherto  received  has  obliged  botanists  to  separate  dissimilar  specimens  of  what  a  more 
copious  supply  might  prove  to  belong  to  the  same  plant.  It  is  to  avoid  any  further  confusion  that  I  have  ven- 
tured to  figure  three  species,  of  which  I  have  no  materials  for  such  an  analysis  of  the  flower  and  fruit  as  a  good 
botanical  drawing  should  possess.  The  C.  cuneata,  in  its  ordinary  form  especially,  appears  one  of  the  most 
distinct  of  these,  and  has  the  leaves  invariably  very  blunt,  larger  at  the  upper  extremity,  and  then  retuse  or 
decidedly  notched :  they  are  rigid  and  coriaceous  in  texture,  and  very  uniform  in  size.  In  the  woods  near  the 
sea  it  forms  a  remarkably  harsh,  woody,  and  repeatedly  branched  shrub,  whose  stems  are  often  2  inches  in  dia- 
meter at  the  base,  and  covered  with  a  rough  black  bark.  The  pale,  but  bright,  red  of  the  berries,  which  are 
abundantly  produced,  forms  a  very  pretty  contrast  amongst  the  deep  shining  foliage.

Hab.  Lord  Auckland's  group  ;  in  ravines  about  600  feet  above  the  sea. 

A  small  and  almost  leafless  bush,  which,  like  its  congeners,  is  very  apt  to  vary  in  its  mode  of  growth.  In 
the  ordinary  state  it  grows  3-4  feet  high,  and  from  the  lower  parts  of  the  stems  and  branches  being  bare  of

leaves,  it  assumes  a  spiny  appearance.     The  leaves  are  patent,  ^— ^  inch  long,  scarcely  coriaceous ;  the  stipules 
hairy  and  ciliated  at  the  margins.

Hab.  Lord  Auckland's  group  ;  in  ravines,  alt.  500-1000  feet.  /3.  In  Campbell's  Island,  in 
shady  situations  near  the  sea. 

A  common  shrub,  especially  in  Lord  Auckland's  group,  where  it  forms  a  densely  branched  bush,  growing 
from  8-10  feet  high.  The  Campbell's  Island  specimens  again  are  very  lax,  twiggy,  and  sparingly  leafy ;  and 
the  leaves,  which  in  a.  are  i— |  inch  long,  are  in  /3.  generally  under  that  size.  I  have  seen  neither  flower  nor  fruit. 
The  bushes  of  the  various  species  of  Coprosma  compose  a  dense  and  impenetrable  thicket,  on  the  margins  of  the 
narrow  gulleys  formed  by  water-courses  on  the  faces  of  the  hills.  Becoming  stunted  and  much  branched  from 
the  violence  of  the  perennial  gales,  they  offer  as  powerful  an  obstacle  to  the  traveller  here  as  the  beeches  do  in 
Tierra  del  Fuego.  In  both  cases  it  is  almost  equally  impossible  to  penetrate  them  ;  but,  extraordinary  as  it 
may  appear,  their  branches  are  so  gnarled  and  densely  matted,  that  their  flat  summits  will  often  bear  the  human 
weight,  and  almost  admit  of  walking  upon  them.

radicula  hilo  proxima,  elongata,  terete  ;   cotyledonibits  latis. 

This  plant  is  apparently  identical  with  a  species  collected  on  Middlesex  Plains,  Tasmania,  by  R.  C.  Gunn, 
Esq.  ;  a  remarkable  circumstance,  as  its  low,  procumbent  mode  of  growth  gives  it  the  appearance  of  being  an 
Antarctic  form  of  the  genus.  The  Auckland  Island  specimens  I  gathered  with  young  and  ripe  fruit  only,  the 
corolla  and  styles  having  invariably  fallen  away.  These  latter,  as  well  as  the  stamens,  I  have  drawn  and  de- 
scribed from  Mr.  Gunn's  specimens,  fully  believing  the  two  plants  to  be  the  same.  I  must  however  here  re- 
mark, that  other  states  from  either  locality  may  be  found  to  possess  unexpected  characters  of  sufficient  import- 
ance to  keep  them  distinct.     I  am  not  aware  of  any  other  species  exhibiting  4  nucules. 

The  prevalence  of  Rubiacea  in  these  islands  is  a  very  singular  fact  in  botanical  geography ;  ranking  as 
they  do  in  number   of  species  next  only  to  Composite  among  Dicotyledonous  plants,  and  almost  equalling 


Campbell's  Islands.]  FLORA  ANTARCTICA.  23 

them  both  numerically  and  in  the  amount  of  space  they  occupy.  In  Antarctic  America  they  are  represented 
by  a  very  few  Stellatce,  which  group  is  here  entirely  absent.  As  no  other  order  exhibits  so  remarkable  an 
excess,  they  probably  balance  the  strangely  disproportionate  want  of  Composite,  which  appear  to  have  almost 
as  few  representatives  in  proportion  to  the  mass  of  exogenous  vegetation  as  any  other  island.  Comparing  the 
dicotyledonous  vegetation  of  the  Falkland  Islands  with  that  of  Lord  Auckland's,  it  will  be  seen,  that  in  the 
former  the  Composite  are  to  the  other  Dicot.  as  1  :  2' 8,  and  that  Rubiacece  (Galium)  are  to  Compos,  as  1  :  21  :  but 
in  the  latter  group,  Compos,  are  to  the  other  Dicot.  only  as  1  :  4'5,  and  Rubiacece  to  Composite  as  1  :  1*6  !  If 
in  each  we  add  these  two  Nat.  Orders  together,  it  will  be  found,  that  in  the  Falklands  the  proportion  which 
the  sum  of  Rubiacea  and  Composite  bear  to  other  Dicotyledonous  plants,  is  as  1  :  2-7,  and  in  Lord  Auckland's 
group  as  1  :  2-3  :  proving,  that  as  far  as  these  two  remote  localities  are  comparable,  Rubiacete  only  balance  in  the 
latter  the  want  of  what  is  generally,  in  all  climates,  the  preponderating  natural  order.  This  is  one  only  of  many 
equally  singular  proofs,  which  a  little  patient  investigation  may  deduce,  that  a  harmony  exists  and  may  be 
traced  in  the  vegetation  of  remote  climates,  whose  Floras  are  otherwise  totally  dissimilar.

Hab.  Lord  Auckland's  group ;  creeping  amongst  moss  in  the  woods,  where  its  bright  red 
berries  give  it  a  pretty  appearance. 

My  specimens  are  unfortunately  not  in  flower  ;  they  however  entirely  resemble  the  figures  of  N.  depressa 
above  quoted,  and  agree  with  numerous  Falkland  Island  and  other  southern  specimens  of  that  plant  with  which 
I  have  compared  it.  In  Mr.  Cunningham's  '  Flora  of  New  Zealand,'  its  precise  habitat  is  omitted  ;  but  it  is 
inserted  in  a  MS.  copy  of  that  '  Flora'  which  formed  part  of  my  library  at  sea.  There  he  mentions  the  "  Falls 
of  the  Keri-Keri  river  "  as  the  only  locality  in  which  he  gathered  it.  In  botanizing  over  that  spot  repeatedly 
in  September  and  October  1841,  in  company  with  Mr.  Colenso,  we  often  met  with  Cunningham's  plant,  both 
there  and  afterwards  in  other  moist  places  near  cataracts  ;  it  is  however  entirely  different  from  the  true  N.  de- 
pressa, being  much  smaller  in  all  its  parts,  with  narrower  and  more  acuminated  leaves.  The  berries  of  the 
Auckland  Island  specimens  are  very  much  vertically  depressed,  and  their  structure  is  entirely  that  of  the  genus 
Coprosma.

A  very  remarkable  genus,  most  nearly  allied  to  Abrotanella,  Cass.  (Oligosporus  emarginatus,  Gaud,  in  Ann. 
Sc.  Nat.  vol.  v.  p.  104.  t.  3.  fig.  4),  but  of  a  very  different  babit,  and  in  many  other  particulars  quite  distinct, 
especially  in  the  more  numerous  scales  of  the  involucre,  inserted  in  two  series,  in  the  many-flowered  capitula, 
the  quadrifid  corollas  of  the  ray,  the  curious  tetragonous  corollas  of  the  disc,  and  the  thickened  cellular  structure 
which  exists  in  several  parts  of  this  plant.  Besides  the  achsenia  having  a  thickened  border  and  keel  in  front, 
formed  of  large  lax  transparent  cells,  the  incrassated  angles  of  the  male  flowers  and  the  three  nerves  of  the 
involucral  leaves,  exhibit  the  same  singular  character.  In  both  the  latter  cases,  the  substance  of  the  organs 
themselves,  which  are  opake  and  fleshy,  seems  to  be  divided  by  broad  lines  of  a  transparent  substance,  marked 
with  transverse  septa. 

Many  of  the  discoid  Senecionidea,  and  especially  in  the  tribe  Hippice  of  Lessing,  are  remarkable  for  the 
curious  and  anomalous  structure  of  their  inflorescence.  In  several  instances,  as  in  the  present,  it  may  be 
doubted  whether  the  flowers  of  the  ray  are  really  tubular,  the  general  unequal  division  and  oblique  aperture 
of  the  mouth  appearing  to  indicate  their  true  structure  as  either  ligulate  or  2-lipped ;  2-lipped  perhaps  in  the 
present  and  the  following  genus,  and  assuredly  1-lipped  or  ligulate  in  Abrotanella,  where  I  observe  the  three  teeth 
all  to  point  towards  one  side  of  the  tube,  with  the  middle  one  the  longest.  The  teeth  in  this  species  have  the 
margins  thickened,  and  apparently  revolute.  The  base  of  the  style  is  peculiarly  incrassated,  especially  in  the 
female  flower,  having  the  base  of  the  corolla  swollen  around  it,  and  the  thickened  portion  often  forms  a 
depressed  sphere,  in  which  the  style  seems  to  be  inserted,  and  it  sometimes  assumes  the  appearance  of  a  fleshy 
ring  or  corona,  surmounting  the  top  of  the  ovary. 

The  name  is  adopted  in  allusion  to  the  three  cellular  nerves  or  lines  of  the  ovary  and  involucral  scales.

1 400  feet ;  very  sparingly.

crassatis  transversim  septatis  pellucidis,  interiores  angustiores.     Flores  parvi,  purpurei. 

This  plant  is  perhaps  more  closely  allied  to  the  last  genus  (Trineuron)  than  to  any  other,  and  exhibits  many 
remarkable  points  of  affinity  with  it,  especially  in  the  pellucid  thickened  parts  of  the  flower  and  nerves  of  the 
involucral  leaves  ;  likewise  the  general  structure  of  the  capitula,  corollas,  stamens  and  styles  is  much  alike  in 
both.  But  while  so  many  instances  of  resemblance  exist,  the  totally  different  nature  of  the  achtsnium  becomes 
the  more  striking.  In  the  tufted  habit,  harsh,  coriaceous,  even  horny  texture,  the  plant  is  more  allied  to  Abro- 
tanella  emarginata. 

These  three  genera  form  together  a  small  group,  allied  in  several  respects  to  Hippia,  Lessing,  but  na- 
turally distinct,  all  the  species  of  that  division  being  herbaceous,  more  or  less  odorous,  and  often  even  furnished 
with  pellucid  glands. 

The  name  is  derived  from  the  little  horn-like  processes  of  the  achaenium.

transmitted  to  England  ;  but  it  is  not  ascertained  who  found  them,  though  it  is  more  than  probable  they  were 
gathered  by  some  person  accompanying  a  sealer.  It  is  the  only  Composite  plant  as  yet  known  to  inhabit  Ker- 
guelen's  Island,  where  it  covers  very  large  tracts  of  ground  with  its  silvery  and  beautifully  feathery  foliage, 
smelling  strongly,  but  not  unpleasantly,  of  parsley.  The  female  corollas  of  both  species  are  represented  as  they 
being  of  my  original  sketches  :  when  dried  they  seem  much  more  compressed,  their  membranous  texture- 
appear  in  such  extreme  tenuity,  that  it  is  probable  they  never  recover  their  original  form  after  once  being  sub- 
jected to  pressure.

28  FLORA  ANTARCTICA.  [Auckland  and 

Hab.  Lord  Auckland's  group ;  on  banks  near  the  sea. 

In  many  respects  this  species  is  intermediate  between  the  two  former,  but  is  equally  distinct  from  both, 
and  so  nearly  allied  to  the  L.scariosa,  as  to  induce  me  to  adopt  the  name  of  propinqua;  it  differs  from  that 
plant  in  its  much  larger  size,  more  divided  leaves  and  very  woolly  habit.  The  genus  Leptinella  appears  to  have 
been  hitherto  but  little  understood  by  botanists  ;  it  was  founded  by  Cassini  in  1822,  upon  (apparently  very  im- 
perfect) specimens  of  two  plants  whose  habitat  was  entirely  unknown.  In  1841  it  was  again  taken  up  by  the 
authors  of  '  Contributions  to  a  Flora  of  South  America,  &c.'  (vide  Hook.  Journ.  Bot.  vol.  iii.  p.  325),  where  a 
supposed  new  species,  L.  acano'ules,  H.  and  Arn.,  is  described.  This  latter  is  a  very  common  plant  in  the  ex- 
treme south  of  the  American  continent,  and  we  have  assumed  it  to  be  thei.  scariosa  of  Cassini  and  DeCandolle, 
the  leaves  and  peduncle  being  either  smooth  or  hairy  in  that  plant.  There  are  still  some  characters  described 
by  the  above-mentioned  authors  as  belonging  to  that  genus  which  my  specimens  do  not  exhibit.  Thus  all  the 
flowers  are  stated  in  one  species  to  be  females  :  I  do  not  find  this  to  be  the  case  ;  nor  should  much  stress  be 
laid  upon  a  peculiarity  of  structure,  drawn  from  a  single  capitulum  "  dont  les  fleurs  sont  extremement  petites  et 
defigurees  ou  alterees  par  la  desiccation  et  la  compression"  (Cassini  in  Diet.  Sc.  Nat.  vol.  xxvi.  p.  67).  In 
all  the  plants  of  the  genus  which  I  have  examined,  the  heads  of  flowers  are  monoecious  ;  but  the  flowers  of  the 
disc  especially,  being  all  males,  are,  after  the  performance  of  their  functions,  easily  displaced  by  pressure.  The 
"long,  straight,  linear,  obtuse,  bracteiform  leaf"  (Diet.  Sc.  Nat.  I.e.)  at  the  base  of  the  peduncle  is  also  not 
apparent ;  nor  am  I  able  to  conceive  to  what  organ  of  our  plant  this  can  apply,  except  a  young  cauline  leaf, 
generally  present  near  the  peduncle,  can  have  assumed  such  a  form  or  suffered  mutilation.  On  the  other  hand, 
the  description  of  the  involucral  scales,  covered,  as  are  the  flowers,  with  glands,  and  the  characters  drawn  from 
those  organs  themselves,  will,  collectively,  accord  with  no  other  plants  that  have  ever  fallen  under  my  notice. 
The  second  described  species,  L.  pinnata,  seems  hardly  to  differ  from  the  L.  scariosa,  except  indeed  that  the 
notice  of  the  above-mentioned  glands  is  under  it  omitted ;  but  Cassini  further  mentions  the  singular  character 
of  the  female  corolla  being  "  enflee,"  an  anomalous  structure,  upon  which  I  shall  here  offer  a  few  remarks. 

In  all  the  four  species  of  the  genus  with  which  I  am  acquainted,  the  style  of  the  flowers  of  the  ray  is 
invested,  or  sheathed  loosely,  by  a  very  delicate  hyaline  tube,  marked,  in  several  instances,  by  distinct  slen- 
der nerves,  always  five  in  number.  This  tube  enlarges  around  the  swollen  bulb  of  the  style  and  is  inserted 
underneath  it  into  the  apex  of  the  achanium  :  at  its  summit  it  meets  the  inflated  corolla,  and  in  the  form  of 
a  membrane  or  tissue  completely  continuous  with  it,  they  together  constitute  the  four  obtuse,  inconspicuous, 
rounded  lobes  of  the  corolla.  The  latter  organ,  thus  viewed,  consists  of  two  distinct  membranes,  united  above 
and  perhaps  below.  On  first  observing  this  structure  in  L.  plumosa,  whose  flowers  are  not  furnished  with 
glands,  and  whose  corolla  is,  so  far  as  I  can  detect,  entirely  nerveless,  I  was  inclined  to  consider  the  corolla  as 
reflected  upon  itself,  the  reflected  portion  entirely  investing  and  concealing  the  real  tube  :  because  I  was  unable 
to  trace  any  intervening  tissue  connecting  the  two  parietes  or  opposite  coats,  where  an  apparent  complete  va- 
cuity exists ;  and  especially  because  in  some  allied  genera  of  Cotulece,  and  in  other  plants  not  far  removed  from 
the  present  genus,  the  corolla  is  reflected,  and  in  a  Tasmanian  species  as  much  as  half-way  down  its  whole  length, 
its  lower  free  margin  being  obscurely  four-lobed  ;  and  in  Otochlamys,  DeC,  its  base  is  produced  downwards  so 
as  to  hide  a  great  portion  of  the  achaenium.  On  the  other  hand,  in  the  three  species  which  are  supplied 
with  glands,  it  is  only  the  outer  surface  of  the  exterior  coat  of  the  corolla  which  is  furnished  with  these  organs. 
Were  this  outer  membrane  the  reflected  limb  of  the  corolla,  the  true  situation  of  the  glands  would  be  on  its 
inner  surface  ;  but  though  appendages  of  the  cuticle  are  not  uncommon  on  the  surface  of  both  ligulate  and  tu- 
bular flowers  of  Composite,  I  am  not  aware  of  their  ever  existing  on  that  surface.  The  oblique  mouth  of  these 
corollas  and  the  constantly  unequal  divisions  at  its  apex,  of  which  one  is  always  the  largest,  seem  to  point  out 
the  larger  tooth  as  being  analogous  to  the  ligula  of  radiate  capitula,  especially  as  one  of  the  four  teeth  is  often 
suppressed.  Lastly,  the  five  nerves,  which  are  most  evident  in  L.  lanata  on  the  inner  tube,  are  not  visible  on 
the  outer  ;  it  is  very  difficult  to  trace  their  termination,  but  they  do  unite  at  the  summit  of  the  tube,  forming 


Campbell's  Islands.]  FLORA  ANTARCTICA.  29 

as  many  arches  as  there  are  nerves,  apparently  without  reference  to  the  number  of  teeth  of  the  corolla,  in  the 
thickened  substance  of  which  they  are  entirely  lost.  Amongst  the  discoid  groups  of  Senecionidea,  there  are  many 
anomalous  structures  of  the  female  corollas.  Thus,  in  Stromjylosperma,  Less.,  the  limb  of  that  organ  is  reduced 
apparently  to  a  very  short  tube,  completely  continuous  with  the  achaenium  ;  and  one  of  the  principal  characters 
of  SoUva,  R.  and  Pav.,  consists  "  in  the  want  of  corolla  or"  (as  Mr.  Brown  remarks)  "  perhaps  its  accretion 
with  the  persistent  style"  (vide  Linn.  Trans,  vol.  xii.  p.  101).  The  original  species,  L.  scariosa,  Cass.,  was 
transmitted  alive  to  England  from  Cape  Horn,  and  is  now  cultivated  in  the  Royal  Botanic  Gardens  at  Kew, 
where  it  blossoms  copiously,  and  as  it  increases  rapidly  and  has  been  widely  distributed,  I  hope  that  the  atten- 
tion of  microscopic  observers  will  be  directed  to  the  singular  structure  of  its  flowers.  Though  possessed  of  no 
beauty,  it  derives  an  interest  from  being  one  of  the  most  Antarctic  flowering  plants. 

The  glands,  so  conspicuous  in  this  and  some  of  the  other  species ,  appear  to  be  conglobate  and  formed  of  about 
four  very  prominent  papillae,  confluent  at  their  margins;  in  this  species  and  in  L.  scariosa  they  are  transparent, 
but  in  L.  lanata,  after  drying,  they  turn  opake  and  whitish.  I  observed  that  in  the  fresh  state  they  contained 
no  evident  secretion  or  essential  oil,  nor  can  they  be  connected  in  any  way  with  the  peculiar  odour  which  several 
of  the  species  possess,  as  this  is  inodorous  or  nearly  so,  and  L.  plumosa,  which  smells  strongly,  is  unprovided 
with  these  organs.

Hab.  Lord  Auckland's  group  and  Campbell's  Island ;  confined  to  rocks  at  the  tops  of  the  hills 
in  the  former  locality ;  abundant  in  the  more  southern  islands,  trailing  over  rocks  and  banks  near 
the  sea.  Also  found  on  Mount  Egmont,  in  the  Northern  Island  of  New  Zealand,  at  an  altitude  of 
4000  feet,  by  Dr.  Dieffenbach. 

This  is  a  graceful  and  very  elegant  plant,  in  many  places,  and  especially  on  the  low  grounds  of  Campbell's 
Island,  covering  the  banks  with  its  silvery  foliage  and  abundance  of  flowers.  It  differs  from  all  other  species 
of  the  genus  Helichrysum,  DeC,  in  the  prostrate  straggling  habit,  and  in  the  stems,  which  are  scarcely  thicker 
than  a  sparrow's  quill,  being  leafy  throughout  their  length,  irregularly  branched,  with  the  branches  divaricating, 
ascending  at  their  apices,  and  there  bearing  the  solitary  capitula ;  whereas  the  Australian  species  particularly  are 
of  an  erect  growth,  those  of  a  more  herbaceous  habit  with  larger,  as  it  were  radical  leaves  at  the  base  of  the 
stem.  It  is  however  the  conical  and  elongated  receptacle  that  removes  this  species  so  far  from  the  212  de- 
scribed in  DeCandolle  ;  a  character  so  evident,  and  of  such  importance,  as  almost  to  induce  me  to  raise  the  pre- 
sent plant  into  a  new  genus.  It  is  further  to  be  remarked,  that  though  the  genus  is  extensively  distributed 
throughout  Australia  and  Tasmania,  where  it  does  not  inhabit  the  mountains,  in  New  Zealand  it  is  represented 
hj  the  present  species  alone,  which  is  confined  to  the  most  elevated  mountains  of  the  Northern  Island,  and  only 
descends  to  the  lower  grounds  in  a  much  higher  southern  and  more  rigorous  latitude. 

The  leaves  are  rather  scattered  upon  the  stems,  -^  inch  long,  elliptical-obovate,  produced  into  a  short 
petiole,  rather  membranous  in  texture,  silvery  white  from  the  dense  appressed  tomentum  beneath,  above  pale 
green  and  opake,  covered  with  scattered  silky  arachnoid  hairs,  the  margins  quite  entire.  The  capitula  are  i-| 
of  an  inch  across  the  ray,  pure  white  or  faintly  tinged  with  rose-colour,  the  outer  scales  shorter,  subulate  or 
lanceolate,  cobweby  with  a  loose  tomentum.  Flowers  of  the  disc  very  small,  almost  concealed  by  the  copious 
white  or  pale  straw-coloured  pappus.  Tube  of  the  corollas  4-cleft,  the  segments  puberulous  externally  towards 
the  apex.     Anthers  biaristate  at  the  base.

A  very  common  and  striking  plant,  often  covering  a  great  extent  of  ground,  and  forming  the  larger  pro- 
portion of  the  food  of  the  hogs  which  now  run  wild  upon  the  islands  of  Lord  Auckland's  group.  It  is 
indeed  so  abundant  in  the  marshy  spots  on  the  latter  islands  that  these  animals  frequently  live  entirely  amongst  it, 
especially  when  it  grows  near  the  margins  of  the  woods,  where  they  form  broad  tracks  or  runs  through  the 
patches,  grubbing  up  the  roots  to  a  great  extent,  and  by  trampling  down  the  soft  stems  and  leaves  use  them  as 
soft  and  warm  forms  to  litter  in.  The  leaves  are  exceedingly  handsome,  generally  two  feet  long  and  one  or  a 
little  more  in  breadth,  from  their  concavity  holding  a  considerable  quantity  of  the  rain-water  or  melted  snow 
which  so  frequently  falls  in  those  latitudes ;  in  substance  they  are  coriaceous,  but  not  nearly  so  much  so  as 
in  the  preceding  species,  and  they  are  more  copiously  silky.  A  full-grown  leaf  is  generally  traversed  by  30-40 
parallel  strong  nerves,  very  prominent  on  the  under  surface  and  then  dark-coloured  and  nearly  glabrous, 
depressed  on  the  upper  with  longer  silky  hairs.  The  intervening  parenchymatous  substance  is  traversed  by 
numerous  slender  anastomosing  veins,  beneath  densely  clothed  with  a  white  appressed  cottony  wool,  and 
above  silky  with  scattered  subarachnoid  hairs.  The  hairs  and  woolly  substance  which  clothe  all  the  stems,  leaves 
and  pedicels  of  the  capitula  are  formed  of  simple  terete  transparent  matted  filaments.  I  do  not  find  amongst 
them  any  of  the  short  rigid  beaded  setae  which  are  intermixed  with  the  softer  hairs  of  the  P.  speciosum.  The 
capitula  are  15-20  in  number ;  the  lower  ones  only  bracteate  with  the  uppermost  leaves,  the  terminal  generally 
having  a  smaller  elongate  subulate  nearly  glabrous  green  bract.  The  intermediate  ones  are  the  most  densely 
silky  on  both  sides,  often  so  much  so  as  entirely  to  hide  the  nerves  ;  in  these,  too,  the  curious  but  minutely 
spinuloso-serrate  character  of  the  margin  is  most  easily  detected  ;  the  apices  of  the  serratures  are  callous  and 
glabrous,  almost  entirely  hid  amongst  the  silky  tomentum. 

Though  this  plant  is  nearly  allied  to  the  former  species  (P.  speciosum),  and  agrees  with  it  in  all  the  most 
important  characters,  they  materially  differ  in  the  more  outward  points  of  resemblance.  Indeed  I  only  know 
one  genus  to  which  the  present  plant  bears  any  marked  similarity  in  general  habit  and  appearance,  and  that  is 
the  ArgyroxypMum,  DeC.  (Prodr.  vol.  v.  p.  G68  ;  Hook.  Ic.  Plant,  vol.  i.  p.  75).     The  mode  of  growth  of  these

two  plants  is  the  same,  and  both  are  natives  of  Pacific  Islands,  abounding  in  peculiarly  inclement  localities ; 
the  present  being  an  inhabitant  of  the  Antarctic  regions,  while  the  Argyroxyphium  is  found  only  on  the  sum- 
mits of  the  highest  mountains  on  the  Sandwich  Islands.  Mr.  Douglas  brought  it  from  the  volcano  of  Mouna 
Kaah,  which  reaches  an  altitude  of  18,400  feet,  -where  it  was  one  of  the  last  plants  he  met  with,  and  he  used 
its  dead  stems  for  fuel.  In  the  clothing  and  substance  (as  far  as  can  be  judged  from  dry  specimens)  of  the 
stem,  in  the  disposition  of  the  inflorescence  and  form  of  the  involucral  scales,  and  in  the  short  ligula?  of  the 
flowers  of  the  ray,  these  plants  entirely  accord  :  and  the  lower  leaves  of  the  latter,  though  uniform  in  size  and 
shape  with  the  upper,  and  having  the  margins  quite  entire,  are  always  clothed  with  a  similar  but  more  beautiful 
and  dense  silky  coat  of  hairs.  On  a  further  examination  of  the  form  of  the  corollas  and  acha?nia  the  analogy 
ceases.  It  must  not  however  be  overlooked,  that  the  pappus  of  P/europhyllutn,  though  composed  of  setae  (and 
not  of  short  palea?),  is  of  a  peculiarly  harsh  and  rigid  texture,  with  each  seta  flattened  and  scabrid  on  the  opposite 
margins,  quite  unlike  the  soft  character  that  organ  assumes  in  most  Composite,  both  showing  its  affinity  to  other 
Asteroidete,  and  some  approach  to  the  short  rigid  palese  of  the  Sandwich  Island  plant.  Although  the  Argyro- 
xyphium is  placed  by  DeCandolle  in  Senecionidca ,  its  styles  appear  to  me  to  differ  in  no  important  particular  from 
those  of  the  PleurophyUum  and  of  other  large  Asteroid  genera.  In  both  these,  the  styles  of  the  flowers  of  the 
ray  are  always  longer  than  those  of  the  disc,  with  the  arms  also  longer,  linear,  obtuse  and  flattened,  erect  or 
diverging  in  most  of  the  tribe,  divaricated  and  inclined  to  become  revolute  in  ArgyroxypMum  ;  they  are  invariably 
quite  smooth  throughout,  and  surrounded  with  a  thickened  darker-coloured  border  (the  stigmatic  series),  those 
of  the  corresponding  side  of  each  arm  meeting  at  the  base.  In  the  flowers  of  the  disc  they  are  shorter,  equally 
bordered  with  a  thick  conspicuous  margin,  abruptly  ceasing  at  the  commencement  of  a  conical,  acute,  rather 
broader  apex,  which  is  plane  and  smooth,  or  most  indistinctly  glandular,  on  the  inner  surface,  but  with  the 
margins  and  convex  back  densely  studded  with  elongated  papilla;  or  glands  (the  pollen  collectors)  ;  these 
papilla?,  except  under  a  very  high  power,  appear  as  hairs  :  the  arms  have  further  a  strong  opake  central  nerve 
in  each,  meeting  and  uniting  at  the  base.  In  Argyroxyphium  the  conical  apices  are  very  short  and  studded  with 
long  papilla?,  whence  they  appear  abrupt,  and  each  of  the  arms  is  split  into  two  parallel  lamina?,  between  which 
a  knife  is  easily  inserted,  when  the  midrib  is  seen  remaining  on  the  inner  of  the  two  lamellae,  and  the  stigmatic 
series  on  the  outer.  I  do  not  think  that  in  a  natural  system  the  two  genera  now  under  consideration  should 
be  far  separated  from  one  another,  or  from  the  following  genus  Celmisia,  Cass. 

Though  generally  so  very  bulky  a  plant,  that  an  ordinary  specimen  of  the  PL  criniferum  weighs  many  pounds, 
I  have  seen  it  so  dwarfish  upon  the  mountains  as  barely  to  exceed  a  span  in  height,  with  all  the  leaves  lanceolate, 
more  densely  silky,  and  thus  even  more  nearly  resembling  Argyroxyphium  than  it  does  in  its  ordinary  state. 
The  masses  of  curly  fibres,  which  may  be  taken  up  in  handfulls  from  the  summit  of  the  roots  of  a  common-sized 
plant,  form  a  very  remarkable  character.

from  whose  bases  arose  no  fewer  than  thirteen  flowering  scapes,  ten  of  them  with  the  blossoms  fully  expanded. 
The  delicacy  of  the  rays,  tipped  with  a  faint  rose-colour,  forms  a  striking  contrast  with  the  dark  purple  eye  and 
the  glossy  varnished  deep  green  foliage.  Like  many  other  Antarctic  plants,  it  varies  considerably  in  size,  some 
of  our  specimens  being  scarcely  an  inch  and  a  half  across  the  leaves,  which  lie  densely  compacted  and  all  hori- 
zontally patent,  radiating  from  the  summit  of  the  root  like  the  spokes  of  a  wheel,  of  a  very  coriaceous  texture, 
singularly  smooth  and  shining  like  the  surface  of  a  shell,  or  as  if  covered  with  a  thick  coat  of  copal  varnish  : 
their  apices  in  the  smaller  specimens  are  incrassated  or  the  leaves  are  clubbed  at  the  apex,  from  the  union  of 
the  thick  costa  with  the  equally  incrassated  margins.  This  thickening  extends  to  the  bractese  or  leaves  on  the 
scapes  and  even  to  the  scales  of  the  involucre  ;  when  dry  they  are  of  a  rich  but  pale  yellow-brown  colour. 

The  genus  Celmisia,  as  modified  above,  will  contain  several  species  very  closely  allied  in  habit,  and  all 
bearing  a  much  greater  similarity  to  the  original  Australian  C.  longifolia,  A.  C,  than  the  C.  vernicosa  does. 
Upon  the  closest  examination,  I  can  detect  no  characters  of  sufficient  importance  to  warrant  any  further  subdi- 
vision of  the  following  species,  which  I  shall  therefore  include  under  the  name  of  Eucelmisia,  considering  them 
as  typical  of  the  genus,  near  to  which  the  above -described  species  should  assuredly  rank. 

I  shall  here,  in  a  note,  subjoin  the  characters  of  the  other  species,  and  proceed  with  some  remarks  upon 
them*.

36  FLORA  ANTARCTICA.  [Auckland  and 

C.  longifolia  (1.).  This  is  the  original  species,  whereon  the  genus  was  founded  by  Cassini ;  the  specimens 
having  been  brought  home  by  Gaudichaud  from  the  voyage  of  Admiral  Freycinet,  and  described  in  '  Diet.  Sc. 
Nat.'  vol.  xxxvii.  p.  259.  DeCandolle  considers  Cunningham's  Blue  Mountain  species  (Arctotis  gnaphalodes, 
Cunn.  MS.  in  Herb.  Hook.)  as  identical  with  this.  Our  specimens  differ  from  Gaudichaud's  figure  only  by 
having  the  leaves  much  narrower,  with  their  margins  revolute  and  the  scapes  far  less  leafy  upwards.  The 
achsenia  are  constantly  glabrous,  the  pappus  pale  reddish,  and  the  papillose  part  of  the  arms  of  the  style  is  as  long 
as  the  linear  and  glabrous  portion.  Of  the  C.  spathulata  (2.),  A.  C.  MSS.,  we  have  no  specimens  ;  in  its  gla- 
brous foliage  it  differs  from  all  but  C.  vernicosa.  A  third  species  is  founded  on  a  Tasmanian  plant  not  rare  on  the 
summit  of  Mount  Wellington,  where  it  forms  large  matted  patches.  The  first  specimens  I  had  seen  were  ga- 
thered there  by  Mr.  Frazer,  and  more  latterly  by  myself  and  Mr.  Gunn,  who  detected  it  in  other  mountainous 
parts  of  the  colony.  I  have  called  it  C.  asteliafolia  (3.),  from  the  great  similarity  it  bears  in  foliage,  general 
aspect  and  habitat  to  Aste/ia  alpina,  Br.  The  leaves  are  extremely  variable  in  breadth  and  in  the  degree  of  re- 
curving in  their  margins  ;  they  are  often  very  like  those  of  C.  longifolia,  but  never  exceed  a  span  in  length.  The 
scapes  too  are  longer,  less  leafy,  and  the  flowers  larger  than  in  that  species  ;  the  hairy  achsenia  also  afford  a 
constant  character.  The  flowers  of  the  ray  are  pink,  the  pappus  yellow.  The  above  three  species  are  Austra- 
lian. Those  found  in  New  Zealand  are  C.  gracilenta  (4.),  a  plant  so  very  near,  even  in  the  variable  form 
of  its  leaves,  to  C.  longifolia,  that  it  was  not  till  I  had  examined  the  styles  that  I  could  detect  any  differ- 
ence ;  the  conical  papillose  portion  of  these  being  much  produced,  gradually  acuminated,  and  three  times  the 
length  of  the  lower  part  of  the  arms,  with  the  papilla;  almost  filiform.  From  C.  astelitefolia  it  differs  in  having 
a  glabrous  achsenium,  which  is  much  longer  than  in  any  of  the  former  species.  Nearly  allied  to  this  is  the 
C.  graminifolia  (5.),  mainly  distinguished  from  the  former  by  its  foliage.  Decidedly  the  finest  species  are 
the  three  following,  two  of  them  originally  discovered  and  described  by  Forster  ;  the  first  is  C.  spectabilis  (6.), 
of  which  I  possess  a  specimen  from  Mr,  Bidwill.  Though  hardly  exceeding  a  span  in  length,  including  the 
scape,  the  base  of  the  stem,  while  covered  with  the  sheathing  leaves,  is  fully  an  inch  in  diameter,  and  densely 
clothed  with  long,  beautifully  silky  wool.  The  leaves  are  broad  and  remarkably  coriaceous,  their  upper  surface, 
in  the  dried  state,  minutely  striated  with  anastomosing  lines,  and  the  under  densely  clothed  with  buff-coloured 
appressed  tomentura.  The  scape  is  stout,  loosely  covered  with  shaggy  white  wool,  and  producing  a  large,  solitary, 
apparently  white  flower,  an  inch  and  a  half  broad.  The  achaenia  are  elongated,  all  of  them  glabrous  ;  the  tubes 
of  the  corolla,  especially  of  the  ray,  have  long,  straight,  pellucid,  scattered,  distantly  jointed,  and  very  slender 
hairs.  Pappus  yellow,  rigid  ;  the  outer  setae,  as  in  the  other  species  of  the  genus,  short,  the  rest  gradually  length- 
ening. Ligules  of  the  flowers  of  the  ray  linear,  abruptly  truncated,  with  three  large  teeth  and  four  nerves.  Anthers 
shortly  biaristate  at  the  base  ;  styles  with  the  arms  rather  elongated,  the  conical  papillose  portion  of  those  of 
the  disc  short  and  rather  obtuse.  Forster's  first  species,  C.  holosericea  (Aster,  Forst.),  has  been  found,  I  be- 
lieve, by  that  botanist  alone  :  his  specimens  exist  in  the  British  Museum,  accompanied  by  his  fine  drawing  of

both  the  present  and  the  last  species.  Richard  (Flora  Nova?  Zelandia?,  p.  249)  described  it  from  other  and 
less  perfect  individuals,  aided  by  Forster's  MS.  in  the  Museum  of  the  Jardin  des  Plantes  at  Paris.  He  how- 
ever does  not  notice  its  affinity  to  Celmisia,  and  considers  the  C.  coriacea  as  probably  a  variety  of  it,  though 
Forster's  figures  essentially  differ  in  general  appearance,  and  other  characters  are  found  in  the  parts  of  the 
inflorescence  of  no  less  importance,  the  achamia  described  by  Richard  being  "silky  and  stipitate"  (attenuated?) 
at  the  base.  Mr.  Cunningham,  in  his  '  Prodr.  Flor.  Nov.  Zeland.,'  first  noticed  the  probable  relation  existing 
between  these  last  two  species  and  Celmisia  (Cass.).  The  scales  of  the  involucre  in  all  the  New  Zealand  spe- 
cies, except  C.  vernicosa,  are  narrow  and  almost  subulate,  becoming  recurved  and  finally  squarrose  in  the  older 
capitula ;  this  is,  however,  a  variable  character. 

I  may  here  mention  another  little-known  New  Zealand  plant,  originally  discovered  by  Forster,  and  called 
by  him  Arnica  oporina  (Forst.  Prodr.  n.  290) ;  it  is  nearly  allied  both  to  these  and  the  former  genus  Pleuro- 
phyllum.  I  have  carefully  examined  specimens  from  Dusky  Bay,  gathered  by  Mr.  Menzies,  and  others  from 
Chatham  Island,  received  from  Dr.  Dieffenbach.  The  achaenia  are  ribbed  and  hairy,  the  pappus  rigid,  rather 
scanty,  pale-coloured,  scabrous,  and  of  very  unequal  seta?.  The  tubes  of  the  corollas  in  the  ray  are  glabrous,  in 
those  of  the  disc  slightly  hairy.  In  both  flowers  the  arms  of  the  style  precisely  resemble  those  of  Celmisia  and  are 
very  long,  those  of  the  disc  with  short  papillose  extremities.  A  comparison  of  this  plant  with  the  genus  Chiliotri- 
chum  of  Cassini,  (published  in  DeCandolle's  Prodromus,  vol.  vi.  p.  216,  and  Hooker's  Icones  Plantarum,  vol.  v. 
t.  485)  does  not  enable  me  to  detect  any  generic  distinction  :  the  arms  of  the  style  in  the  flowers  of  the  ray 
are  indeed  rather  longer  in  the  latter  and  slightly  attenuated  upwards,  and  the  achaenia  are  glandular  and  not 
hairy.     Both  approach  very  closely  the  genus  Eurybia,  Cass.,  or  Olearia,  Mcench.

Dubii  generis. 

Amongst  the  plants  collected  in  Lord  Auckland's  group,  are  two  apparently  belonging  to  the  natural  order 
Composite,  but  which,  in  the  absence  of  flower  or  fruit,  I  am  unable  to  place  under  any  genus.  One  of  these 
may  belong  to  Gnaphalium,  but  is  quite  different  from  any  New  Zealand  or  other  species  which  has  come  under 
my  notice.  The  only  specimen  of  it  which  I  possess  was  gathered  by  Mr.  Lyall,  and  consists  of  apparently  a 
few  radical  leaves,  or  probably  of  a  young  plant  whose  stems  are  not  yet  produced  upwards.

Hab.  Lord  Auckland's  group;  on  the  sea-beach,  D.  Lyall,  Esq. 

The  woolly  substance  which  entirely  clothes  the  leaves  and  stem  of  this  plant  is  formed  of  simple,  terete, 
transparent,  matted  filaments,  similar  to  that  of  Gnaphalium  luteo-album,  L.,  to  some  states  of  which  this  bears 
a  good  deal  of  resemblance.  It  may  with  equal  probability  be  referred  to  a  species  of  Heliehrysnm,  and  except 
that  the  apices  of  the  leaves  are  not  apiculate  or  mucronate,  it  has  much  the  appearance  of  young  plants  of 
H.  apiculatum,  Lab. 

The  other  plant,  if  I  am  right  in  referring  it,  as  I  do  with  little  hesitation,  to  Composite,  forms  one  of  the 
most  handsome  shrubs  or  low  trees  belonging  to  that  natural  order.  It  was  also  detected  by  Mr.  Lyall,  from 
whose  specimens  I  shall  here  give  a  short  description  : —

Hab.  Lord  Auckland's  group  ;  Ewing  Island,  a  small  islet  at  the  mouth  of  Rendezvous  Har- 
bour, D.  Lyall,  Esq. 

Of  this  plant  Mr.  Lyall  remarks,  "  A  short  stout  trunk  rises  a  few  inches  above  the  ground,  and  then  sends 
off  horizontally  patent  branches,  which  radiate  as  from  a  common  centre  for  10  or  12  feet  on  all  sides,  a  little 
above  the  surface  of  the  earth.  The  leafy  apices  then  ascend.  The  leaves  are  of  a  dark  green  colour,  which 
they  lose  in  drying."  A  piece  of  the  wood  which  accompanied  the  specimen  is  about  1|  inch  in  diameter  ; 
the  bark  of  a  light  grey  colour,  rather  thin  and  soft,  deeply  grooved  on  the  surface,  the  grooves  corresponding 
to  sinuous,  anastomosing,  longitudinal  ridges,  enclosing  elongated,  somewhat  lozenge- shaped  spaces  ;  the  wood 
is  whitish  or  pale  yellow,  hard,  tough  and  close-grained,  the  layers  indistinct,  and  the  medullary  rays  nume- 
rous and  very  slender  ;  it  resembles  the  stem  of  some  shrubby  species  of  Ozothamnus.  This  fine  plant  is  most 
remarkable  for  the  size  and  thick  coriaceous  texture  of  the  leaves,  which  are  in  many  respects  similar  to  those 
of  the  genus  Brachyglottis,  Forst.  I  have  seen  nothing  like  it  in  the  collections  of  Banks  and  Solander, 
Forster  or  Menzies.  It  is  a  rare  plant  in  the  islands  now  under  consideration,  and  will  probably  be  found  to  be 
a  native  of  the  southern  extremity  of  New  Zealand.

Though  abundant  upon  the  hills  of  Lord  Auckland  and  Campbell's  Islands,  this  plant  has  not  hitherto  been 
brought  from  any  part  of  New  Zealand,  neither  from  the  mountains  of  the  Northern  Island,  whence  Mr.  Bidwill 
and  Mr.  Colenso  have  sent  home  several  of  the  more  common  Antarctic  species,  nor  in  the  southern  parts  of  that 
group,  so  well  explored  by  Forster  and  Menzies.  In  general  habit  and  appearance  it  bears  a  greater  similarity 
to  the  Phyllachne  uliginosa,  Forst.,  than  to  its  New  Zealand  congener,  Forstera  sedoides,  L.,  although  in  the 
more  essential  characters  it  is  much  more  nearly  allied  to  the  latter,  the  leaves  being  entire,  the  calycine  seg- 
ments equal  and  regular,  and  the  epigynous  glands  much  developed.  In  other  respects,  and  especially  in  the 
mode  of  growth  and  form  of  the  leaves,  the  present  plant  is  so  dissimilar  from  either,  that  I  have  ventured  to 
place  it  under  a  separate  sectional  name,  adopted  in  allusion  to  the  incrassated  apices  of  the  leaves. 

There  are  several  points  in  the  structure  of  the  three  plants  above  alluded  to  which  seem  to  require  some 
consideration  ;  and  having  the  opportunity  of  examining  the  flowers  of  all  the  species,  I  shall  here  offer  a  few 
remarks  upon  them,  premising  that,  except  in  the  case  of  F.  clavigera,  the  specimens  at  my  disposal  were  too 
few  to  allow  of  the  full  verification  of  the  observations. 

Linnaeus  first  supposed  Phyllachne  to  be  monoecious  (Suppl.  Plant,  p.  62),  and  Swartz  (Schrader,  Journ. 
fur  Botanik,  vol.  i.  p.  273,  translated  in  Koenig's  Annals,  vol.  i.  p.  286)  follows  Forster  (Charact.  Gen.  t.  58) 
in  supposing  both  this  and  F.  sedifolia  to  be  dioecious.  If,  as  I  suspect,  the  only  truly  fertile  flowers  of  F.  cla- 
vigera are  such  as  bear  the  uncinate  plumose  styles,  that  plant  is  certainly  monoecious.  Out  of  very  many 
flowers  examined,  I  only  found  such  stigmata  in  two,  both  of  which  had  abortive  anthers,  and  they  were  more- 
over furnished  with  the  only  capsules  in  which  I  saw  the  immature  seeds  brown,  and  apparently  fertile.  Though 
there  is  a  marked  difference  in  the  development  of  the  apex  of  the  style  in  the  abortive  flowers  of  this  plant,  it 
never,  that  I  have  seen,  approaches  the  form  it  bears  in  the  fertile  flowers  ;  at  all  other  times  it  is  exceedingly 
minute  and  probably  variable  in  the  lobes.     Of  the  P.  uliginosa  1  examined  six  flowers,  only  one  of  which 


40  FLORA  ANTARCTICA.  [Auckland  and 

contained  perfect  stigmata ;  in  it  the  style  branched  into  two  capitate  arms,  pubescent  externally,  and  in 
all  respects  analogous  to  the  stigmata  of  the  former  plant ;  the  ovary  was  however  in  so  very  young  a  state, 
that  I  could  not  detect  any  concomitant  character  in  the  ovules  ;  the  anthers  were  decidedly  abortive.  In 
F.  sedi/olia,  L.,  I  have  seen  no  other  stigmata  than  two  small  uncinate  fleshy  bodies,  concealed  between  the 
two  upper  valves  of  the  anthers,  parallel  with  them,  and  alternating  with  two  small  glands  ?  at  the  back  of  these 
organs.  In  form  and  situation  they  answer  to  the  plumose  stigmas  of  the  two  former,  but  they  are  smooth 
throughout.  In  another  flower  I  find  the  apex  of  the  style  to  be  depressed  and  to  appear  minutely  4-lobed, 
with  the  lobes  unequal  and  rounded  :  in  both  these  cases  the  anthers  were  full  of  pollen,  and  the  ovules  in  a 
rudimentary  state.  In  Swartz's  description  of  this  plant  he  notices  a  crest  of  projecting  hairs,  arising  from  a 
fleshy  septum,  obscurely  lobed  under  the  microscope,  which  connects  the  two  anthers  and  separates  the  two 
lobes  of  the  true  apex  of  the  style  or  stigmas.  Swartz  distinctly  alludes  to  the  two  small  glands  or  stigmata 
as  being  protected  by  the  upper  valves  of  the  anthers,  and  they  are  hence  probably  analogous  to  two  of  the  four 
lobes  into  which,  in  the  flower  I  examined,  the  apex  of  the  style  appeared  to  be  divided.  Swartz's  supposition, 
that  the  septum  and  crista  of  fine  hairs  form  a  connectivum  between  the  anthers,  separating  the  stigmata,  appears 
to  me  to  indicate  a  most  anomalous  condition  of  those  parts  ;  and  as  it  is,  from  its  position  and  structure,  analogous 
to  the  arms  of  the  style  and  stigmata  in  the  two  former  species,  I  conclude  that  that  author  examined  fertile 
flowers  of  F.  sedi/olia.  It  is  still  more  remarkable  that  so  acute  and  very  accurate  an  observer  should  have  been 
unable  to  detect  the  glands  at  the  base  of  the  column,  which  in  both  my  specimens  are  exceedingly  large,  and 
project  upwards  like  two  horns  from  the  top  of  the  ovarium  for  half  the  length  and  upwards  of  the  tube  of  the 
corolla,  and  wrhose  apices  in  the  young  state  of  the  flower  lie  between  the  anthers.  It  is  possible  that  they  may 
be  obscurely  developed  in  fertile  flowers  of  this  species,  which  however  is  not  the  case  in  those  of  F.  clavigera 
or  of  Phyllachne  uliginosa. 

In  F.  clavigera  there  are  apparently  two  very  different  states  of  the  corolla  :  in  many  of  my  specimens  of 
this  plant  that  organ  is  divided  into  5-7  lobes,  all  of  them  concave  and  even,  of  the  same  thickness  throughout ; 
more  rarely  they  are  4  or  9  ;  but  in  other  corollas  taken  from  the  same  specimens  the  divisions  are  undulated, 
with  the  borders  of  the  sinuses  much  thickened,  and  each  of  them  furnished  at  the  throat  with  two  linear,  elevated, 
divaricating  ridges  or  glands,  which  branch  off  from  the  middle  nerve  in  the  upper  part  of  the  tube,  and  are 
abruptly  clavate  at  the  extremity,  near  the  margin  of  the  segment,  with  whose  thickened  margins  they  some- 
times unite.  In  some  respects  they  resemble  the  nectaries  of  Ranunculus  pinguis  (Tab.  I.),  being  only  occasion- 
ally present ;  they  however  contain  no  secretion.  Though  I  could  trace  no  connection  between  this,  the  common 
form  of  the  corolla,  and  the  fertile  or  abortive  state  of  the  ovarium,  I  may  remark,  that  where  the  segments  are 
smooth  and  even,  the  apex  of  the  style  is  hardly  prominent  or  visible  between  the  anthers,  and  also  that  in  the 
most  divided  corollas  the  segments  were  most  undulated  and  thickened  ;  in  F.  sedi/olia  they  are  also  very 
distinct,  though  nowhere  described  that  I  am  aware  of;  and  they  are  also  evident,  but  not  so  fully  developed,  in 
the  few  flowers  of  Phyllachne  which  I  have  examined.  I  have  also  described  the  corolla  as  somewhat  two-lipped, 
a  character  not  very  evident  in  all  instances,  and  depending  upon  the  inequality  and  comparative  size  of  the 
segments  ;  one  or  two  are  almost  invariably  larger  than  the  rest,  and  external  in  aestivation  ;  when  there  are  two 
large  lobes  they  are  placed  near  one  another ;  and  when  the  corolla  has  more  than  five  segments,  these  two  are 
subdivided  into  four  by  short  sinuses  ;  where  only  four  segments  exist,  it  is  caused  by  the  union  of  two  of  the 
small  lobes. 

All  the  species  have  the  anthers  spuriously  2-celled,  by  means  of  a  thick  fleshy  ridge  which  runs  at  the 
base  of  the  anther,  between  the  valves,  and  projects  half-way  across  the  cavity.  After  the  dehiscence  of  these 
organs,  they  together  form  a  cross  placed  horizontally  on  the  top  of  the  column,  from  their  unsymmetrical  con- 
traction ;  of  these,  the  lower  one  on  each  side  projects  horizontally  and  forms  a  right  angle  with  the  axis  of  the 
column,  its  two  lower  lobes  approximating  below  ;  the  upper  becomes  erect,  and  its  upper  margin  being  revolute, 
meets  that  of  the  opposite  anther;   this  appearance  is  represented  at  fig.  10.     The  ovary,  which  is  generally 


Campbell's  Islands.]  FLORA   ANTARCTICA.  41 

1 -celled,  I  have  rarely  found  divided  into  two  cells  by  a  more  or  less  thickened  septum.  Two  bundles  of  vessels, 
one  from  each  of  the  arms  of  the  style,  meet  in  the  column  and  traverse  its  length  ;  at  the  summit  of  the  ovarium 
they  sometimes  again  divide,  and  as  separate  cords  enter  its  cavity,  meeting  again  in  the  central  column  whicli 
bears  the  placenta?. 

The  last  circumstance  to  which  I  shall  here  allude  concerns  the  inflorescence  of  these  species  of  Stylidiem. 
In  one  of  Mr.  Bidwill's  specimens  of  F.  sedi/olia  from  the  mountain  of  Tongariro,  in  the  Northern  Island  of 
New  Zealand,  the  peduncle  is  2-flowered,  and  the  position  of  the  bracts  on  the  pedicels,  and  at  the  base  of  the 
ovaria,  shows  their  true  situation  and  the  nature  of  the  inflorescence  to  be  the  same  in  Forstera  as  in  many 
Stylidia.  This  two-flowered  specimen  has  six  bracts,  two  of  which  are  placed  at  the  forking  of  the  peduncle, 
one  situated  upon  and  belonging  to  each  of  the  pedicels ;  but  the  other  four  form  two  pairs,  each  pair  placed  imme- 
diately at  the  base  of  the  ovarium.  In  the  solitary  and  sessile-flowered  species  it  is  sometimes  difficult  to  di- 
stinguish the  bracts  from  the  upper  leaves  ;  in  F.  clavigera  however  they  are  sufficiently  distinct,  but  never  more 
than  two,  nor  in  P.  uliginosa  are  there  probably  more,  though  they  gradually  pass  into  the  ordinary  forms  of  the 
leaf.  In  the  latter  plant  some  foliaceous  expansions,  which  are  generally  considered  as  segments  of  the  calyx, 
are  often  placed  upon  the  germen  ;  I  have  not  remarked  how  they  are  disposed  upon  distinctly  fertile  ovaria  of 
this  species ;  where  however  that  organ  is  imperfectly  developed,  it  may  be  readily  understood  how  a  little 
irregularity  in  the  insertion  either  of  the  calycine  lobes  or  bracts  might  lead  to  the  one  being  mistaken  for  the 
other.

A  very  distinct  species,  of  which  I  much  regret  that  I  have  not  more  satisfactory  specimens  which  would 
allow  of  an  examination  of  the  expanded  flowers.  The  peduncles  of  the  bud  and  of  the  berry  are  so  remark- 
ably short,  as  at  once  to  point  out  this  as  very  distinct  from  any  others  of  the  genus  ;  and  it  further  differs  from 
all  the  other  round-leaved  species  in  the  size  and  obscure  toothing  of  the  leaves,  their  very  short  petioles,  and 
in  the  red-purple  colour  of  the  berries.     It  is  most  nearly  allied  to  the  P.  angulata  (vide  infra). 

Having  had  the  opportunity  of  examining  some  species  of  Pratia  in  Herb.  Hooker,  I  shall  here  append  the 
characters  of  all  that  are  known  to  me  as  certainly  belonging  to  this  genus* ;  besides  which,  there  are  several

other  New  Zealand  and  New  Holland  solitary-flowered  creeping  Lobeliacea  with  unilabiate  corollas,  but  in  the 
absence  of  any  specimens  with  fruit  I  am  unwilling  to  add  them  here. 

The  genus  Prat  la  was  established  by  M.  Gaudichaud  on  a  species  detected  by  himself  in  the  Falkland 
Islands,  the  P.  repens,  which  was  first  described  in  Ann.  Sc.  Nat.  vol.  v.  p.  103  {anno  1825);  but  the  original 
discoverers  of  the  genus  were  Banks  and  Solander,  who,  during  Captain  Cook's  first  voyage,  gathered  the  P. 
angulata  in  New  Zealand  (in  1769)  :  to  the  species  of  M.  Gaudichaud  there  was  first  added  another  from  La 
Plata  by  M.  Chamisso  (Linnsea,  vol.  viii.  p.  212),  and  more  lately  what  appears  to  me  a  truly  distinct  species  was 
published  as  a  variety  of  this  last,  under  the  name  of  P.  hederacea,  (i.  elliptica(vi&z  Hook.  Bot.  Journ.  vol.  i.p.  278). 
I  have  seen  the  fruit  of  all  these  except  the  P.  hederacea,  and  they  agree  with  the  characters  of  Pratia.  In  1839 
M.  Alph.  DeCandolle  removed  the  Pratia  begonifolia,  Wall.,  and  erected  it  into  a  separate  genus,  Piddingtonia, 
mainly  on  account  of  the  2-lipped  corolla ;  besides  this  character  of  the  corolla,  which  has  the  two  outer  lobes 


very  variable  in  length,  as  is  the  corolla  itself  and  the  tube  of  the  calyx  in  shape,  the  form  of  the  latter  depending 
upon  the  greater  or  less  maturity  of  the  seeds. 

4.  P.  hederacea,  Cham. ;  ramis  repentibus,  foliis  petiolatis  membranaceis  late  ovatis  rotundatisve  crenato-

most  distinctly  unilabiate.  It  is  very  different  from  the  true  P.  hederacea,  a  plant  those  authors  were  not  then 
acquainted  with,  and  in  many  respects,  especially  in  the  distichous  leaves,  it  resembles  the  P.  Cunninghamii.

regions  of  New  Zealand,  especially  as  it  is  particularly  abundant  in  Lord  Auckland's  group,  where  it  creeps 
over  the  ground  and  forms  low  wiry  bushes,  resembling  the  Crow-berry  (Empetrum  nigrum);  the  flowers  are  very 
inconspicuous,  smaller  than  those  of  any  other  plant  of  the  Nat.  Ord.  with  which  I  am  acquainted.  The  ripe 
fruit  I  have  never  seen  ;  Mr.  Bidwill  describes  the  plant  as  bearing  a  white  berry.  The  name,  from  avi)p  (stamen) 
and  fTTOfia  (os,  oris),  is  adopted  in  allusion  to  the  position  of  the  stamens,  wherein  the  chief  distinction  lies 
between  this  genus  and  Lissanthe,  Br.

A  most  abundant  plant,  forming  a  great  portion  of  the  woods  which  skirt  the  shores  of  these  islands.  The 
true  Drucophyllum  longifolium  has  hitherto  been  known  to  botanists  only  through  the  specimens  collected  by  the 
Forsters  during  Cook's  second  voyage,  and  to  some  of  the  few  who  possess  portions  of  the  valuable  collection 
formed  by  Mr.  Menzies  in  Dusky  Bay.  Mr.  Forster  made  full  descriptions  of  his  specimens,  which  have  been 
published  by  M.  Richard,  and  as  a  few  discrepancies  occur  in  comparing  our  own  specimens  with  his,  I  shall  here 
allude  to  them,  premising  that  they  only  refer  to  such  characters  as  depend  much  on  the  different  localities  the 
plant  may  inhabit.  That  the  above-described  plant  is  specifically  the  same  as  that  gathered  both  by  Forster  and 
Menzies,  is  evident  on  the  comparison  of  my  specimens  with  the  original  drawing  of  that  author.  Thus,  the 
leaves  are  described  as  smooth  and  reflexed  :  they  are  only  so  in  the  younger  and  more  luxuriant  state  of  the 
trees  in  Lord  Auckland's  Islands  ;  as  they  grow  larger  and  more  exposed  to  the  violence  of  the  climate  they 
become  strict,  erect,  rigid,  coriaceous  and  pubescent  above,  all  of  which  characters  Mr.  Menzies'  specimens 
possess,  except  that  they  are  also  smooth.  Again,  the  spikes  are  solitary  in  the  young  trees,  but  in  the  older 
most  frequently  from  2-5  together  ;  I  have  however  never  seen  them  nearly  a  palm  long,  or  indeed  more  than 
two  inches ;  in  the  British  Museum  drawings  they  are  about  that  length.  The  tube  of  the  corolla  is  hardly  if 
at  all  longer  than  the  calyx,  and  not  "  duplo  longior,"  and  its  segments  can  hardly  be  considered  as  acute. 
The  present  species  is  certainly  most  nearly  allied  to  the  D.  squarrosum  (vide  in  note,  p.  48),  but  the  leaves  are 
broader  and  more  rigid,  and  the  corolla  of  quite  a  different  shape.

A  very  peculiar  species,  most  nearly  allied  to  the  D.  Lessonianum,  A.  Rich.,  and  D.  Urvillianum,  A.  Rich., 
but  very  distinct  from  both.  It  has  also  been  gathered  upon  the  Chatham  Islands  by  Dr.  Dieffenbach,  in  whose 
specimens  the  leaves  are  most  beautifully  margined,  and  the  backs  of  the  bracteae  covered  with  a  silvery  and 
velvety  pubescence.  I  do  not  however  place  much  reliance  on  the  pubescence  of  any  of  the  species  of  this  genus, 
which  appears  a  very  variable  character. 

The  genus  Draeophyllum  was  established  by  Labillardiere  upon  the  D.  verticillatum,  a  plant  of  New  Cale- 
donia (vide  Voyage  de  Labill.  vol.  ii.  p.  211.  t.  40),  and  afterwards  adopted  by  Mr.  Brown,  who  added  the 
D.  secundum  of  Australia  as  a  second  species ;  both  these  have  the  flowers  racemose  or  panicled,  the  bracteas 
caducous,  and  the  stamens  either  hypogynous  or  inserted  at  the  very  base  of  the  corolla.  In  a  subgenus  or 
section  called  Sphcnotomu,  the  latter  botanist  included  some  other  New  Holland  plants  with  spiked  flowers, 
persistent  bracteas,  and  stamens  inserted  upon  the  corolla  ;  this  has  since  been  erected  into  a  genus  by  Mr. 
Sweet  (Fl.  Austral,  t.  44),  and  retained  as  such  by  all  future  authors.  Mr.  Brown  having  further  remarked 
that  some  of  Forster's  New  Zealand  Epacridece,  as  E.  longifolium  and  E.  rosmarinifolium,  Forst.,  belonged  to 
the  genus  Draeophyllum,  as  modified  by  him,  they  were  forthwith  published  as  such  by  M.  A.  Richard,  who  added 
two  more  species  to  the  genus,  and  also  by  Cunningham,  who  published  a  third  (D.  latifo/ium)  ;  but  none  of 
these  authors  proposed  any  sectional  characters  for  these  species,  which  differ  most  materially  from  those  of 
Mr.  Brown's  first  section  of  the  genus,  in  many  of  them  having  epipetalous  stamens,  as  also  in  the  flowers  being 
spiked  and  the  bractese  persistent,  and  which  equally  differ  from  Sphenotoma  in  habit  and  the  form  of  the 
corolla.  Lastly,  M.  DeCandolle,  in  1839,  remodelled  the  generic  character  of  Draeophyllum,  and,  intending  it  to 
include  only  the  plants  of  Mr.  Brown's  first  section,  described  the  calyx  as  "  ebracteatus,"  and  the  stamens  as 
"  corolla?  non  adnata,"  both  characters  the  opposite  of  what  most  of  the  New  Zealand  species  exhibit. 

Having  received  several  allied  new  species  of  this  genus  from  New  Zealand,  I  shall  add  their  characters 
here  and  give  a  conspectus  of  the  whole,  both  for  the  purpose  of  showing  the  position  of  D.  longifolium  and  D. 
scoparium  in  the  series,  as  also  because  I  am  anxious  to  seize  the  first  opportunity  afforded  me  of  laying  the  new 
species  before  the  public  and  remodelling  this  fine  genus*.     I  may  here  remark,  that  as  a  genus  it  is  an  exceed-

the  common  species  on  the  banks  of  the  Keri-Keri  river.  His  MSS.  name  of  D.  attenuatum  is  also  attached  by 
himself  to  specimens  (in  Herb.  Hook.)  of  Lessonianum  and  not  of  Urvilleanum,  under  which,  in  his  '  Prodromus,' 
he  quotes  his  own  name  as  a  synonym.

This  is  not  an  uncommon  plant  in  the  woods  at  the  sources  of  rivers  which  fall  into  the  Bay  of  Islands, 
New  Zealand,  and  it  has  also  been  gathered  in  other  parts  of  the  Northern  Island  of  New  Zealand,  where  it 
assumes  a  more  straggling  and  less  woody  appearance  than  the  Auckland  Island  specimens  present.  It  is  the 
only  shrub  which  in  this  longitude  Inhabits  a  level  so  nearly  that  of  the  ocean  in  the  respective  latitudes  of  35° 
and  52^°  S.  Mr.  Cunningham,  who  first  detected  this  species,  describes  the  berries  as  spotted  with  black;  in 
the  southern  specimens,  which  may  in  this  respect  be  a  variety,  they  are  of  a  uniform  pale  blue,  and  quite 
unmarked. 

I  have  ventured  to  retain  M.  A.  Richard's  generic  name  of  Suttonia  for  this  and  several  other  Myrsinea 
of  New  Zealand,  and  though  that  author  gives  no  etymology  of  the  name,  I  cannot  but  suppose  it  was  adopted 
as  a  well-merited  compliment  to  the  Rev.  Dr.  Sutton  of  Norwich,  one  of  the  original  members  of  the  Linnsean 
Society  of  London,  and  author  of  an  excellent  paper  on  the  British  species  of  Orobanche,  read  before  that 
Society  in  1797  (vide  Linn.  Soc.  Trans,  vol.  iv.  p.  193). 

The  other  species  which  will  be  included  under  Suttonia,  as  above  characterized,  are  (1.)  S.  australis,  A. 
Rich.  (Myrsine  Urvillei,  Alph.  DeC.  ;  Myrsine  undulata,  A.  Cunn.  ;  Merista  laevigata,  Banks  and  Sol.  MSS.); 
(2.)  S.  tenuifolia*,  n.  sp.  ;  (3.)  S.  salicina  (Myrsine  salicina,  Hew.  MSS.).  All  these  have  the  petals  free, 
except  the  last,  in  which  they  are  slightly  adherent  at  the  base,  and  they  further  differ  from  Myrsine  in  having 
solitary  or  rarely  (in  M.  salicina  alone)  two  ovules  and  seeds.  The  original  discoverers  of  the  genus  were  Sir 
J.  Banks  and  Dr.  Solander,  who,  accompanying  Captain  Cook  during  a  five-months'  investigation  of  various 
parts  of  the  shores  of  New  Zealand,  were  the  first  Europeans  that  ever  landed  there,  and  the  indefatigable  col- 
lectors of  most  of  the  singular  and  new  forms  of  plants  with  which  those  islands  abound.  The  name  Merista, 
given  by  them  to  one  of  the  species,  was  probably  adopted  in  allusion  to  the  division  of  the  corolla.  The  draw- 
ing and  description  of  M.  Richard  were  made  from  very  imperfect  specimens,  and  the  genus  incorrectly  referred 
to  Terebinthace  e. 

The  Myrsinea  are  for  the  most  part  inhabitants  of  climates  whose  temperature  is  equable,  and  they  particu- 
larly abound  in  insular  localities,  as  the  islands  of  the  Indian  Ocean,  Mauritius,  Bourbon,  and  Madagascar.  Their 
utmost  northern  limit  in  the  old  world  seems  to  be  the  Azores,  lat.  39°  N.,  Madeira,  lat.  32°,  and  Teneriffe  ; 
but  in  no  part  of  the  adjacent  continent  of  Africa  do  they  cross  the  northern  tropic  ;  in  Europe  they  are  entirely 
wanting,  and  in  Asia  extend  only  to  Japan,  in  north  latitude  40°.  The  order  is  very  rare  in  North  America, 
and  especially  to  the  northward  of  Mexico,  only  one  species  inhabiting  the  United  States,  the  M.  Floridana,  A. 
DeC,  and  that  is  confined  to  the  southern  state  whose  name  it  bears,  lat.  30°  N.  In  the  southern  hemisphere 
they  nowhere  (except  in  New  Zealand)  are  found  to  the  southward  of  the  36th  parallel,  and  there  in  S.  Brazil 
only.     In  Africa  they  reach  the  33rd,  and  the  34th  in  Australia.     Their  extension  into  the  53rd  degree  in  the

South  Pacific  Ocean  is  hence  a  remarkable  circumstance,  and  probably  in  some  measure  to  be  accounted  for 
by  the  uniform  temperature  which  the  New  Zealand  Islands  possess  ;  they  further  there  bear  a  larger  proportion 
to  the  other  dicotyledonous  vegetation  than  they  do  in  any  other  part  of  the  globe.  I  have  alluded  to  the 
S.  divaricata  having  a  considerable  range  in  latitude,  a  circumstance  not  without  parallel  in  the  order  to 
which  it  belongs.  Of  this  M.  Africana,  L.  is  an  extreme  instance,  that  plant  being  found  both  at  the  Cape  of 
Good  Hope,  in  Abyssinia,  and  in  the  Azores  Islands.  The  species  of  the  Natural  Order  are  however,  as  M.  A. 
DeCandolle  well  remarks  (Linn.  Trans,  vol.  xvii.  p.  99),  very  confined  as  regards  their  geographical  limits, 
MelastomacecB  and  Myrtaceos  being  two  of  the  very  few  groups  containing  about  the  same  or  a  greater  number 
of  species  which  are  more  so.

This  elegant  little  species  is  one  of  the  most  attractive  plants  on  the  exposed  hills,  flowering  copiously  in 
November  and  December.  The  variety  /3.  is  rather  uncommon  and  seldom  flowers ;  its  appearance  is  more  that 
of  a  large  leafy  state  than  of  perfect  or  characteristic  specimens.  The  y.  I  have  never  found  in  flower,  and  it 
may  prove  a  distinct  species,  though  the  roots  are  annual  and  its  leaves  of  the  same  nature  as  some  of  the  larger 
specimens  of  G.  concinna.  The  former  of  these  varieties  approaches  the  G.  montana,  Forst.,  of  New  Zealand, 
Tasmania  and  Australia,  itself  a  very  variable  plant,  according  to  our  own  and  Forster's  original  specimens 
in  the  British  Museum,  and  to  the  description  of  Forster  quoted  by  Richard  (Fl.  Nov.  Zel.  p.  203),  and  the 
works  of  Brown  and  Grisebach  (Gen.  et  Sp.  Gentian,  p.  235).  All  the  states  of  the  latter  however  differ  from 
this  in  the  much  larger  flowers,  acute  lobes  of  the  corolla,  and  long  peduncles  of  the  flowers.  The  present 
plant  affords  further  a  proof  of  a  certain  similarity  in  the  whole  Flora  of  the  south  circumpolar  regions,  a  pecu- 
liarity more  strongly  marked  in  the  analogous  latitudes  of  the  Northern  hemisphere,  where  large  tracts  of  land 
with  a  concomitant  vegetation  are  situated  nearer  the  pole.  I  must  confess  that  I  have  much  difficulty  in  recog- 
nising more  than  one  species  in  Tasmania,  which  is  itself  closely  allied  to  several  South  Chilian  and  Patagonian 
plants,  as  G.  Patagonica,  Griseb.,  G.  multicaulis,  Gill,  and  G.  diffusa,  H.  B.  K. 

I  am  here  anxious  to  correct  an  error  I  have  fallen  into,  in  considering  the  G.  Grisebachii  (Hook.  fil.  in  Ic. 
PI.  t.  636)  as  distinct  from  G.  montana,  Forst.  ;  I  have  lately  had  the  opportunity  of  examining  large  suites  of 
specimens  of  the  true  plant,  of  which  the  G.  Grisebachii  is  decidedly  a  small  state.  And  so  also  with  regard  to 
the  G.  bellidifolia  (Ic.  PI.  t.  635) ;  though  different  from  the  ordinary  states  of  Forster's  G.  saxosa,  and  especially 
from  the  specimens  from  which  he  made  his  drawings,  it  is  not  specifically  distinct  from  other  states  which  have 
been  gathered  by  Forster,  but  which,  when  the  G.  bellidifolia  was  published,  I  had  not  the  opportunity  of 
examining.

During  our  stay  in  Lord  Auckland's  group  I  much  regretted  being  unable  in  my  drawings,  to  imitate  the  pel- 
lucid and  waxv  appearance,  especially  of  the  flowers  and  leaves  of  this  most  beautiful  plant,  to  which  in  other 
respects  the  artist  has  done  ample  justice.  It  bears  nearly  the  same  relation  to  the  G.  saxosa,  Forst.,  as  the  former- 
described  species  does  to  G.  montana.  Though  placed  by  Dr.  Grisebach  (in  his  excellent  Essay  on  Gentianece)  in 
separate  sections  of  that  genus,  there  appears  to  me  to  be  but  little  to  remove  these  two  species  far  from  one  another, 
except  the  annual  root  of  one.  As  is  the  case  with  G.  saxosa,  the  leaves  of  this  are  variable  in  breadth,  but  not 
to  the  same  extent,  and  it  entirely  differs  from  that  plant  in  the  prostrate  habit  of  growth,  very  short  peduncles 
of  the  flowers,  and  in  the  broader  and  shorter  corollas,  which  are  not  much  longer  than  the  lobes  of  the  calyx.  The 
anthers  in  all  the  New  Zealand  as  in  the  Tasmanian  species  are  versatile  on  the  apex  of  the  filament,  which  is 
curved  and  at  first  projects  forward  ;  after  the  discharge  of  the  pollen,  or  rather  the  first  dehiscence  of  the  anthers, 
the  apex  of  the  filaments  immediately  becomes  erect  and  then  reflexed,  whence  in  the  expanded  flowers  the 
anthers  are  almost  invariably  found  to  be  extrorse.  Although  Gentians  are  seldom  white-flowered  as  species, 
this  and  the  former  are  decidedly  so,  with  red  or  red-purple  at  the  base  of  the  segments,  and  the  veins  of  the 
same  colour ;  the  pure  blue  of  the  European  species  is  unknown  amongst  those  of  these  regions,  or  of  the  higher 
latitudes  of  South  America.  Indeed  I  think  that  few  genera  display  so  full  a  series  of  colours  in  the  flowers  as 
this  does;  red,  blue,  yellow  and  white  are  all  exhibited  in  it,  with  many  of  the  intermediate  compound  tints. 
Yellow  and  white  are  rare  in  the  regions  of  the  Gentians,  but  almost  invariably  present ;  the  red  species  are 
nearly  confined  to  the  Andes  of  South  America  and  New  Zealand.  Amongst  Dr.  Jameson's  '  Botanical  Notes  on 
the  Flora  of  the  Andes  of  Peru  and  Colombia'  I  find  the  following  interesting  remark:  "Of  sixteen  species  of  Gen- 
tian with  which  I  am  acquainted,  one-half  are  red,  four  purple,  two  blue,  one  yellow,  and  one  white."  (Bot. 
Journ.  vol.  ii.  p.  649.)  Their  inferior  limit  under  the  line  we  find  from  the  same  source  to  be  7852  feet,  and  they 
ascend  from  thence  nearly  to  the  limits  of  perpetual  snow  on  Cotopaxi*  ;  they  do  not  in  South  America  descend 
to  the  level  of  the  sea  in  a  lower  latitude  than  54°  or  thereabouts,  where  however  there  are  no  alpine  species, 
though  the  snow-line  does  not  descend  below  4000-3500  feetf.  In  the  Himalayan,  where  the  species  are  all 
blue-flowered,  one  species  has  been  gathered  by  my  friend  Mr.  Edgeworth  near  Ratha  Kona,  on  the  ManaPass, 
at  an  elevation  of  16,000  feet,  near  the  limit  of  perpetual  snow  ;  and  another  reaches  in  lat.  31°  N.  the  altitude  of 


*  15,646  feet,  Jameson,  I.e.  p.  657.  The  mean  lower  limit  of  perpetual  snow  on  the  Andes  under  the 
equator  is  at  an  altitude  of  15,748  feet,  according  to  Humboldt;  and  15,496  from  the  mean  on  six  mountains 
measured  by  Dr.  Jameson.

12,689  feet,  according  to  Dr.  Royle  (Must.  Plant.  Himmal.  vol.  i.  pp.  22  and  278).  In  Ceylon  a  species  has 
been  gathered  at  between  6000  and  8000  feet  of  elevation.  One  species,  G.prostrata,  H.  B.  K.,has  a  most  extra- 
ordinary range,  both  in  longitude  and  latitude  :  in  southern  Europe  it  inhabits  the  Carinthian  Alps,  between 
6000  and  9000  feet  high  ;  in  Asia  it  has  been  found  on  the  Altai  mountains  about  lat.  N.  52°.  Its  American 
range  is  much  more  remarkable,  it  having  been  gathered  on  the  tops  of  the  Rocky  Mountains  in  lat.  52°  N., 
where  they  attain  an  elevation  of  15,000-16,000  feet,  and  on  the  east  side  of  the  Andes  of  South  America  in 
35°  S. :  it  descends  to  the  level  of  the  sea  at  Cape  Negro  ;  in  the  Straits  of  Magalhaens  in  lat  53°  S. ;  and  at 
Cape  Good  Hope  in  Behring's  Straits,  lat  683-°  N. 

The  fact  of  the  occurrence,  and  the  great  number,  of  species  of  Gentiana  inhabiting  only  the  more  elevated 
regions  of  the  temperate  and  tropical  zones,  and  there  reaching  the  snow  limit,  renders  it  very  remarkable  that 
they  should  be  so  proportionally  scarce  in  the  higher  latitudes  both  of  the  northern  and  southern  hemispheres. 
Generally  speaking,  the  inhabitants  of  these  elevated  and  cold  regions  are  species  of  such  Natural  Orders  and 
genera  as  compose  the  mass  of  the  Polar  vegetation.  It  is  so  to  a  great  extent  with  certain  groups  of  Ranun- 
culacete,  of  Graminete,  Caryophyllea,  Cruciferee,  Ericeee,  &c.  &c,  but  not  with  Gentianem ;  the  proportion  which 
the  species  of  the  transition  temperate  zones  bear  to  the  other  plants  of  those  regions  on  the  one  hand,  and  to 
the  tropical  species  of  the  same  genus  on  the  other,  is  in  both  cases  remarkably  small.  They  are  entirely 
unknown  to  the  Floras  of  the  Polar  American  Islands  ;  very  few  inhabit  Greenland,  Iceland,  or  the  Arctic  sea- 
shores in  the  North,  or  Tasmania,  New  Zealand,  Fuegia,  or  the  Antarctic  Islands  in  the  South;  and  again  in 
other  parts  of  N.  Europe  and  America,  or  of  Chili  and  Patagonia,  they  are  infinitely  less  numerous  than  in  the 
Alps  of  Middle  and  South  Europe,  or  the  Andes  of  the  equator.

the  M.fulva,  Hook,  and  Arn.,  which  inhabits  the  west  coasts  both  of  extratropical  North  and  South  America, 
chiefly  differs  from  this  in  the  shorter  tube  of  the  white  corolla,  and  in  the  calyces  being  densely  covered  with 
silky  fulvous  or  pale  brown  hairs.

This  is  a  very  small  species^  typical  of  a  high  latitude  and  rigorous  climate,  preferring  also  those  localities 
where  few  other  plants  but  lichens  and  mosses  can  exist.  It  is  remarkable  as  belonging  to  a  small  section  of 
the  genus,  apparently  confined  to  the  islands  of  New  Zealand,  of  which  the  M.  spathulata,  Forst.,  is  the  type. 
These  have  many  of  the  lower  flowers  solitary  in  the  axils  of  the  uppermost  leaves,  and  the  true  ebracteate 
raceme  reduced  to  a  very  short  and  few-flowered  spike. 

The  leaves  of  several  of  the  New  Zealand  species  of  Boraginece  so  closely  resemble  one  another  in  form, 

that  unless  good  flowering  specimens  are  examined,  two  genera  may  easily  be  considered  as  belonging  to  one 

and  the  same  plant.     Such  are  a  species  of  Exarrhena,  Br.,  and  the  M.  spathulata  of  A.  Richard.     The  latter 

is  a  very  distinct  plant  from  either  M.  capitata  or  M.  antarctica,  as  also  from  the  true  spathulata  of  Forster,

and  has  been  described  and  figured  (in  Mus.  Banks)  as  M.  riglda,  Banks  and  Sol,  MSS.  Forster  accurately 
describes  the  flowers  of  his  plant  as  solitary,  most  of  them  being  truly  so  ;  but,  from  its  being  similar  in  all 
other  respects  to  a  plant  brought  home  from  New  Zealand  by  Admiral  D'Urville,  except  in  the  latter  having 
the  flowers  in  a  raceme,  M.  Richard  altered  (in  his  Flora  Nova;  Zelandire,  p.  198)  the  character  of  Forster. 
His  species  is  probably  the  M.  rigida,  Banks  and  Solander,  or  another  nearly  allied  plant  which  we  possess 
from  New  Zealand. 

The  M.  antaretica  is  certainly  an  extreme  instance  of  any  of  the  species  having  a  leafy  inflorescence  ; 
although  the  genus  is  generally  described  as  having  "  racemus  ebracteatus,"  there  are  some  European  and  even 
British  species,  which,  in  having  the  lower  flowers  solitary  in  the  axils  of  the  uppermost  leaves  removed  from  the 
base  of  the  raceme,  show  an  evident  analogy  to  the  southern  ones. 

Several  of  the  species  of  the  northern  hemisphere,  though  nearly  identical  with  others  of  the  southern,  are 
not  known  to  grow  within  80  or  90  degrees  of  latitude  of  one  another.  This  is  the  case  both  in  the  eastern 
and  western  hemispheres.  A  very  few  are  inhabitants  of  the  elevated  and  cold  regions  of  the  tropics,  under 
the  equator,  where  they  attain,  on  the  Andes  of  South  America,  an  altitude  of  12,000  feet.  In  the  old  world 
the  present  species  represents  the  southern  limit  of  the  genus  ;  especially  as,  from  the  elevation  it  attains  in 
Campbell's  Island,  it  may  be  supposed  capable  of  existing  at  the  level  of  the  sea  in  a  much  higher  southern 
latitude.

Hab.  Lord  Auckland's  group  and  Campbell's  Island;  margins  of  woods  near  the  sea,  abundant. 

This  is  a  very  well-known  plant  in  our  gardens,  introduced  from  the  Falkland  Islands,  and  is  one  of  the 
most  antarctic  trees,  both  in  this  longitude  and  in  that  of  extreme  Southern  America,  there  reaching  the  57th 
parallel  of  latitude.  It  was  first  collected  in  New  Zealand  by  Forster,  its  original  discoverer,  in  Dusky  Bav, 
where  it  has  since  been  found  by  Anderson  and  Menzies.  I  believe  it  however  to  have  been  noticed  before 
as  a  native  of  the  Straits  of  Magalhaens,  by  the  older  navigators. 

In  combining  the  V.  decussata  Ait.  with  V.  eUiptica,  I  have  followed  the  unpublished  opinion  of  Dr. 
Solander.  In  the  British  Museum  there  are  drawings  of  the  latter  plant  by  Forster,  New  Zealand  specimens 
collected  probably  by  that  author,  and  notes  by  Dr.  Solander.  The  specimens  alluded  to  are  in  fruit  only,  and 
agree  in  the  foliage  with  the  figures,  which  represent  it  in  its  flowering  state.    Dr.  Forster's  own  handwriting

(of  V.  elliptica)  is  on  the  same  sheet  with  it ;  but  another  plant,  V.  Menziesii,  Benth.  MSS.,  has  been  fastened 
down  on  the  paper  at  a  future  period,  and  the  habitat  "  New  Zealand,  Dusky  Bay,  Gul.  Anderson,"  is  written 
on  the  back,  a  station  probably  applying  to  the  latter  specimen  alone.  Solander's  handwriting,  of  V.  decussata, 
/>,  at  the  bottom  of  the  sheet,  applies  to  both,  as  in  his  manuscript  he  quotes  both  Forster  and  Anderson  for  the 
species.  I  am  thus  particular  in  alluding  to  the  British  Museum  specimens,  because  there  is  a  discrepancy  be- 
tween the  plant  of  Forster  as  described  by  him,  and  our  own,  according  to  his  MS.  description,  published  by 
M.  A.  Richard,  I.  c,  where  the  tube  of  the  corolla  is  described  as  being  twice  the  length  of  the  calycine  segments, 
and  the  latter  as  subulate.  In  all  our  specimens,  both  from  Lord  Auckland  and  Campbell's  Islands,  as  also  in 
those  of  Antarctic  America,  the  tube  of  the  corolla  is  a  little  longer  than  the  calyx,  sometimes  as  much  as  one- 
third,  but  it  appears  even  more  so  before  the  expansion  of  the  corolla ;  and  by  subulate  that  author  might  have 
alluded  to  the  acuminated  apex  which  the  segments  sometimes  have.  Though  Forster's  drawing  does  not  exhibit 
the  calyx,  it  coincides  too  closely  with  the  preserved  specimen,  and  both  with  our  plant,  to  leave  any  doubt  in  my 
mind  that  we  have  here  another  instance  of  the  similarity  of  the  vegetation  of  the  higher  latitudes.  Dr.  Solander 
indeed  considers  the  New  Zealand  plant  as  a  different  variety  from  the  Southern  American,  and  in  his  MSS. 
description  of  the  southern  species,  to  which  I  have  access  through  the  kindness  of  Mr.  Brown,  he  separates  the 
former  as  "  /3.  floribus  carneis  (Forster),  rami's  glabriusculis.  Frutex  sesquipedalis."  In  Forster's  drawing  the 
mineral  white  used  to  colour  the  flowers  has  become  discoloured,  and  the  pink  alluded  to  by  Dr.  Solander 
almost  obscured  ;  in  our  specimens  they  are  of  a  pure  milk-white  when  fresh.  The  want  of  down  on  the  branches 
arises  from  age. 

In  Lord  Auckland's  group  this  species  attains  a  much  larger  size  than  it  does  in  America,  there  seldom 
exceeding  four  feet  in  height,  whilst  Forster  describes  the  Dusky  Bay  tree  as  twelve  feet,  and  I  have  seen  it  as 
much  as  thirty  on  the  margins  of  the  woods  close  to  the  sea,  where  it  may  be  readily  distinguished  by  its  pale 
green  foliage  and  erect  branches.  I  saw  but  one  specimen  in  full  flower,  growing  on  an  inaccessible  rock 
overlooking  Rendezvous  Harbour ;  from  a  distance  it  seemed  powdered  with  white  flowers. 

In  New  Zealand  this  genus  is  one  of  the  most  extensive  of  flowering  plants,  containing  no  less  than 
twenty-five  species,  of  which  four-fifths  are  shrubby  or  arborescent.  Of  these,  ten  were  originally  discovered 
by  Sir  J.  Banks  and  Dr.  Solander  during  their  visit  to  these  islands,  and  are  described  in  the  MSS.  above 
alluded  to.  Under  one  of  them,  the  V.  macrocarpa,  Dr.  Solander  dwells  upon  that  peculiarity  in  the  structure 
of  the  fruit  which  separates  many  of  them  from  the  European  forms  of  the  genus  :  he  writes,  "  Hsec,  et  quinque 
sequentes,  (V.  sulicifolia,  myrtifolia,  stricta,  pubescens,  parvijlora,)  a  reliquis  Veronicis  diff'erunt,  corolla  subrin- 
gente  et  cupsula  apice  integra  acutiuscula,  ut  fere  proprium  constituant  genus."  Mr.  Brown  (Prodr.  p.  434) 
dwells  more  at  length  on  this  peculiarity,  explaining  the  structure  and  its  modifications,  and  further  using  it  as 
a  sectional  character. 

The  extreme  difficulty  of  determining  the  species  of  this  section  was  also  alluded  to  by  Dr.  Solander,  who 
continues  in  the  MSS.  above  quoted,  "  valde  atfines  sunt,  ut  differentia  specirica  difficillime  eruatur,  prsecipue 
si  specimina  sicca  consulantur ;  nee  ilia  sine  capsulis  distinguere  possibile  est.  Plantae  autem  viva?  habitu  dis- 
crepant, facillimeque  tunc  dignoscuntur,  ut  alias  species  esse  distinctas  credam."  This  difficulty  has  not  been 
a  little  increased  by  the  accession  of  new  species,  similar  to  the  above  in  form  ;  and  the  whole  genus  is  now  so 
large  as  to  require  a  complete  remodelling  ;  this  is  expected  from  the  pen  of  Mr.  Bentham,  to  whom  1  am 
indebted  for  the  discrimination  of  my  species.  As  his  remarks  bear  reference  to  all  the  Auckland  and  Campbell's 
Island  species,  I  shall  avail  myself  of  his  kind  permission  to  give  the  definition  of  the  sections  under  which  they 
will  be  arranged.  "  For  this  section,"  Mr.  Bentham  says,  "  I  adopt  as  sectional  Jussieu's  name  of  Hebe, 
with  the  character  :  capsula  septicido-bipartibilis,  carpeliis  dorso  breviter  intus  profunde  bifidis.  Placentte 
stipitatre.  Folia  crassiuscula,  nitida,  glaberrima,  omnia  opposita.  Racerni  axillares,  v.  ad  apices  ramorum  corym- 
bosi,  v.  paniculati.  Corolla  tubus  latitudine  vix  longior  v.  rarius  brevissimus."  Of  this  section  there  are  five 
subsections,  almost  wholly  composed  of  New  Zealand  species  ;  under  the  second  of  these,  this  and  the  two  follow-

coriacea,  olivaceo-fusca,  basi  profunde   emarginata  circumdata.     Testa  membranacea.     Embryo  clavaformis, 
orthotropus. 

This  is  not  only  a  beautiful,  but  a  very  remarkable  plant,  and  one  of  the  greatest  ornaments  to  the  barren 
hills  it  inhabits,  the  flowers  being  nearly  as  large  as  those  of  V.  elliptica,  Forst.,  and  of  a  most  beautiful  blue 
colour.  In  the  pedicellate  flowers,  crowded  upon  an  erect,  leafy,  terminal  raceme,  a  few  of  which  only  expand 
at  one  time,  it  is  more  nearly  allied  to  some  of  the  British  herbaceous  species  than  to  the  shrubby  group  of  New 
Zealand.  It  may  also  be  remarked,  that  two  of  the  largest-flowered  species,  whose  corollas  are  of  the  finest 
blue,  are  more  alpine  in  their  habitats  than  most  of  their  congeners,  as  is  the  case  with  this  plant  and  with  the 
V.  saxatilis  of  the  European  Alps. 

In  garden  specimens  of  the  V.  speciosa,  R.  Cunn.  (Bot.  Mag.  t.  4057),  I  have  observed  the  calyx  and 
corolla  to  vary  in  the  number  of  parts,  from  three  to  four,  but  I  am  not  aware  that  the  stamens  in  any  species 
except  the  present  ever  exceed  two,  or  that  the  corolla  is  constantly  pentamerous.  The  V.  decussata,  Ait. 
(elliptica,  Forst.)  is  figured  and  described  in  the  'Botanical  Magazine'  by  Mr.  Curtis  (t.  242)  as  sometimes 
having  five  parts  to  the  corolla,  which  is  the  nearest  approach  I  know  of  to  the  present  case.  I  shall  however 
first  point  out  the  remarkable  structure  of  the  calyx,  before  more  fully  describing  the  corolla. 

The  calyx  is  constantly  5-cleft;  the  segments  very  large  and  singularly  unequal  in  size,  two  being  much 
larger  than  the  rest,  always  external  and  of  the  form  of  cauline  leaves  ;  the  other  three  are  nearly  equal,  so  that 
at  first  sight  the  calyx  appears  3-cleft,  with  two  lateral  bracts  on  its  base  ;  the  large  segments  are  however 
remote  from  the  true  bract  on  the  base  of  the  pedicel.  Neither  of  these  is  the  posticous  lobe,  nor  is  the  solitary 
smaller  one  placed  between  them,  which  is  the  lowest ;  but  the  two  others,  one  of  which  is  a  little  larger  than 
the  other,  are  nearly  opposite  the  back  lobe  of  the  corolla. 

The  corolla  is  rather  variable  in  form ;  when  regularly  developed  it  is  5-cleft,  with  rather  broad,  nearly 
equal,  patent  segments,  the  two  lowest  being  the  smallest,  the  upper  the  posticous.  The  segments  are  however 
often  so  very  equal  in  size,  that,  from  their  appearance  alone,  it  is  not  possible  to  judge  which  is  the  upper  one. 
The  increased  number  of  parts  might  be  supposed  to  arise  from  the  division  of  the  back  lobe,  which  is  in  so 
many  Veronicas  the  larger,  and  the  stamens  would  thus  be  placed  one  at  the  outer  base  of  two  contiguous 
segments.  This  however  is  not  the  case  in  any  5-cleft  flowers ;  when  diandrous,  only  one  segment  separates 
them,  which  I  have  seen  to  be  the  upper  when  they  are  equal  in  size,  and  it  is  more  evidently  so  when  two  of  the 
lobes  are  smaller  than  the  rest,  which  are  then  placed  opposite  the  two  stamens  and  are  the  lower.  The  addi- 
tional lobe  is  formed  thus  from  the  division  of  the  lower,  or  what  is  generally  the  smaller,  lobe  in  others  of  the 
genus.  Some  analogy  to  this  structure  may  be  found  in  the  case  of  V.  nivea,  nob.  (Icon.  Plant,  t.  640),  which 
has  the  lower  lobe  truly  bifid,  as  I  have  proved  by  an  examination  of  other  specimens,  and  not  accidentally,  as 
suggested  in  the  description  of  that  plant  on  its  first  publication.  In  some  spikes  all  the  flowers  are  ringent, 
the  tubes  of  the  corollas  longer,  and  the  segments  narrower  than  in  the  normal  state  of  the  plant.  Of  these 
some  are  6-cleft,  of  which  I  found  two  instances,  one  diandrous  and  the  other  triandrous.  In  the  diandrous 
flower  the  sixth  lobe  was  formed  from  the  division  of  the  upper  or  posticous  lobe  into  two  unequal  segments, 
and  one  of  the  stamens  was  abortive  and  inserted  lower  in  the  tube  of  the  corolla  than  the  other.  In  the  tri- 
androus specimen  the  sixth  lobe  was  due  to  the  splitting  of  the  lower  into  three.  We  have  here  instances 
of  both  the  upper  and  lower  segment  in  this  species  becoming  divided.  I  never  saw  any  tendency  in  either  of 
the  lateral  ones  to  divide,  further,  than  that,  in  one  instance  of  a  5-lobed  corolla,  one  of  these  had  a  large 
tooth  on  its  lower  margin.  Three-lobed  corollas  are  rare  ;  the  two  I  examined  were  regular,  with  the  segments 
nearly  equal  and  very  broad.  The  genus  Veronica  is  generally  described  as  having  the  upper  or  back  lobe  the 
largest;  this  is  not  constantly,  though  often  the  case,  but  the  lower  lobe  is  generally  the  smallest,  sometimes 
remarkably  so.  In  V.  nivea,  mentioned  above,  the  lateral  divisions  are  much  the  largest,  as  is  the  case  with 
V.  Cataracts,  Forst.,  and  its  ally  V.  diffusa,  nob.,  very  distinctly.  The  V.  tetragona,  Hook.  (Icon.  Plant,  t.  5S0)  is 
figured  with  the  upper  lobe  bifid ;  it  is  probably  rarely  so,  as  in  all  the  specimens  I  examined  it  was  quite  entire. 


62  FLORA  ANTARCTICA.  [Auckland  and 

In  the  several  instances  of  the  flowers  being  triandrous,  the  stamens  were  all  perfect ;  two  in  the  usual 
position  of  those  organs  in  Veronica,  and  the  third  opposite  the  upper  segment,  and  hence  in  a  position  analo- 
gous to  the  centre  of  the  lower  lobe.  I  found  no  trace  of  abortive  stamina  in  other  parts  of  the  corolla,  or  in 
the  position  of  the  third  stamen  in  diandrous  flowers. 

The  capsules  vary  much  in  size,  from  2  lines  to  nearly  ^rd  of  an  inch  in  length.  Those  with  three  valves 
were  very  large,  and  in  one  instance  occupied  the  whole  raceme  ;  in  other  cases  only  a  few  of  the  capsules 
were  3-celled.  In  most  instances,  and  always  in  the  2-valved,  the  valves  separate  from  the  central  column 
which  bears  the  placenta?  and  seeds,  and  the  dehiscence  is  truly  septicidal.  In  many  of  those  with  the  addi- 
tional valve,  the  capsule  is  only  partially  septicidal,  one  or  more  of  the  valves  separating  from  the  central  column  ; 
whilst  the  inner  margins  of  the  dissepiments  of  the  others  are  united  from  above  the  middle  to  the  base,  with 
the  seeds  attached  to  an  inflexed  portion  and  escaping  at  the  top  of  the  capsule,  which  is  split  no  further  down 
in  front  than  at  the  back ;  in  other  cases  all  the  contiguous  dissepiments  were  thus  united,  and  with  the  valves 
not  separating  at  all,  either  from  the  axis  or  from  one  another,  or  with  the  axis  itself  dividing  into  three  por- 
tions, which  remain  attached  to  the  valves ;  in  both  the  latter  cases  the  capsules  are  spuriously  loculicidal.  I 
am  not  aware  of  this  dehiscence  occurring  in  any  other  of  the  New  Zealand  shrubby  species  of  Veronica,  or  that 
a  3-valved  capsule  has  been  previously  observed  in  the  Natural  Order  Scrophularinece.

This  species  is  more  remarkable  for  the  delicious  fragrance  of  its  flowers  than  for  any  beauty  of  appear- 
ance. From  the  uniform  size  of  the  leaves  and  their  regularly  patent  disposition  on  the  slender  simple  branches, 
it  affords  a  more  striking  example  of  folia  decussata  than  any  of  the  genus.  It  is  in  this  respect  allied  to  the 
V.  elliplica,  Forst.,  as  also  in  having  crowded,  white,  subcapitate  flowers,  and  in  their  being  sweet-scented. 
Most  of  these  characters,  and  especially  that  of  the  corolla  being  white,  seem  more  usual  amongst  the  alpine 
species  of  this  genus  in  New  Zealand,  than  in  those  of  the  lower  lands  of  this  or  of  other  countries. 

There  are  three  other  species  to  which  this  is  allied  ;  V.  diosmwfoUa,  R.  Cunn.,  V.  buxifolia,  Benth.,  and  V., 
Icevis,  Benth.  The  first  of  these,  which  has  also  white  flowers,  may  be  recognized  at  once  by  these  being  in  larf  e 
lax  panicles ;  they  are  small,  on  long,  often  slender  peduncles,  with  acute  calycine  segments  ;  the  leaves 
also  are  longer  and  serrated.  The  V.  buxifolia  is  a  very  fine  alpine  species,  brought  from  the  mountains  of  the 
interior  by  Dr.  Dieffenbach,  which  differs  from  the  V.  odora  in  the  leaves  being  more  densely  imbricated,  shorter, 
shining  on  both  sides,  and  remarkably  truncate  at  the  base  above  the  petiole  ;  it  has  also  very  short,  often  sim- 
ple racemes,  covered  with  large  concave  imbricating  bracts,  as  in  the  V.  Benthami,  but  closer ;  the  tubes  of  the 
corolla  are  sometimes  as  long  as  the  very  broad  segments, — that  organ  is  thus  truly  hypocrateriform  ;  the  leaves 
are  covered  on  both  sides  with  more  numerous  minute  white  dots.  V.  lavis,  Benth.  is  more  nearly  allied  to  our 
plant  than  any  of  the  above  in  the  form  of  the  leaves,  but  they  are  more  acute,  more  distantly  placed,  without 
any  white  dots  ;  the  panicles  also  are  lax,  minutely  pubescent,  the  flowers  smaller,  and  the  branches  sin- 
gularly black  and  opake  when  dry,  terete  and  wrinkled,  with  the  transverse  annuli  or  scars  remote  and  incon- 
spicuous, very  unlike  the  generally  crowded  transverse  contractions  of  its  congeners,  which  often  give  the  stem 
the  appearance  of  being  jointed. 

The  leaves  are  closely  placed  in  V.  odora,  and  each  is  jointed  upon  a  thickening  of  the  stem,  which  thick- 
ened portion  appears  like  a  broad  petiole,  united  to  the  branch,  and  extending  from  the  base  of  the  true  petiole 
to  the  leaf  below,  its  edges  almost  meeting  those  of  a  similar  thickening  below  the  opposite  leaf,  but  leavin"-  a 
furrow  between,  which  is  covered  with  a  fine  pubescence.  As  this  thickening  occurs  opposite  and  below  each 
pair  of  leaves  above  it,  and  the  furrow  to  the  pair  below,  the  stem  is  decussately  furrowed  throughout  its 
length.  In  many,  and  in  most  species  indeed,  the  stem  is  incrassated  below  the  leaf,  but  the  thickened  portion 
has  not,  as  here,  the  appearance  of  a  distinct  body.

This  species  is  very  distinct  from  any  with  which  I  am  acquainted,  and  is  apparently  most  nearly  allied  to 
the  P.  hirtella,  H.B.K.  (Nov.  Gen.  et  Sp.  t.  127),  but  that  plant  has  the  bracteas  and  calycine  segments  acute  ; 
it  grows  nowhere  on  the  low  grounds  of  Lord  Auckland's  group,  but  appears  confined  to  the  summits  of  the 
hills,  where  it  is  not  unfrequent.  It  is  remarkable  for  its  numerous  leaves,  which  are  generally  quite  smooth 
and  very  fleshy,  often  forming  a  dense  head,  not  unlike  that  of  a  small  cabbage.  In  the  smoothness,  thick  and 
succulent  habit  and  stout  collum,  it  bears  some  affinity  to  the  caulescent  species  of  Juan  Fernandez  and  other 
insular  situations  ;  in  some  of  which  the  apparent  stems  are,  as  in  P.  Fer/iandeziana,  Bert.,  in  reality  an  elon- 
gation of  the  naked  collum  :  indeed  of  the  so-called  shrubby  or  caulescent  species,  very  few  of  this  group  or 
form  are  really  so,  except  the  P.  princeps,  Cham,  and  Schl.  (Linnaea,  vol.  i.  p.  167).  The  stem  of  P.  Que- 
leniana,  Gaud.,  is  of  the  same  nature  as  that  of  P.  Fernandeziana,  the  two  plants  indeed  are  very  closely  allied, 
as  are  those  of  P.  arborescens  of  Madeira  and  the  Canary  Islands,  and  of  P.  robusta  of  St.  Helena. 

The  uniform  and  equable  climate  of  insular  situations,  especially  in  the  southern  hemisphere,  would  appear 


Campbell's  Islands.]  FLORA  ANTARCTICA.  65 

peculiarly  favourable  to  a  vigorous  development  of  the  stem  and  leaves  of  plants ;  there  being  no  winter's  cold 
sufficient  to  destroy  even  the  herbaceous  vegetation,  a  constant  accession  of  new  matter  ensues  in  the 
summer,  which  only  decays  with  the  death  of  the  plant.  The  elongation  of  the  collum  is,  under  these  circum- 
stances, very  frequent  amongst  many  truly  herbaceous,  perennial-rooted  plants,  whose  congeners  in  other  cli- 
mates are  cut  off  during  the  winter's  frosts,  close  to  the  ground,  and  where  the  summer  season  is  too  dry  to 
admit  of  much  exposure  of  so  large  a  portion  of  the  root.  In  the  group  of  islands  now  under  consideration,  I 
have  remarked  this  peculiarity  of  structure  in  Ranunculus,  Cardamine,  Sieversia,  Pozoa,  both  species  of  Pleu- 
rophyllum,  Cehnisia,  Gentiana,  and  others.  In  Kerguelen's  Land  a  remarkable  instance  occurs  in  the  famous 
Cabbage  of  that  island,  a  new  genus  and  species  of  Crucifera,  to  which  the  generic  name  of  Pringlea  was  given  by 
its  discoverer  Mr.  Anderson,  and  which  I  shall  shortly  have  the  opportunity  of  figuring  as  P.  antiscorbutica.  In 
the  southern  extreme  of  America  the  P.  monanthos,  D'Urv.,  assumes  this  spuriously  caulescent  form,  as  well  as 
Statice  and  many  other  herbaceous  genera,  and  in  the  various  small  oceanic  islands  the  same  character  prevails. 
As  a  natural  sequence,  it  is  to  be  expected  that  plants  generally  represented  by  small  suffruticose  species,  should 
under  these  circumstances  become  frutescent  or  arborescent,  of  which  we  have  many  instances.  Veronica:, 
Composites,  Araliacea,  Myrtacete,  Rubiacete,  Campanulacete,  Lobeliacece,  and  Ferns,  are  all  more  fully  developed  in 
the  Pacific  islands  in  proportion  to  the  number  of  smaller  species,  and  to  the  mass  of  the  vegetation,  than  they 
are  in  other  climates.

This  plant  was  first  detected  by  Mr.  Brown  in  Tasmania,  in  the  southern  parts  of  which  island  it  is  not 
uncommon,  growing,  as  in  Lord  Auckland's  group,  on  maritime  rocks,  and  from  whence  we  have  specimens  of 
both  varieties  from  Mr.  Gunn.  In  habit  and  foliage  it  most  resembles  the  P.  Coronopus  of  any  European  species, 
but  it  differs  totally  from  that  plant  in  the  structure  of  the  capsule,  as  also  in  the  inflorescence.  It  belongs  to 
a  small  group  of  the  genus,  not  hitherto  recognised,  but  which  are  remarkable  for  having  the  flowers  solitary  or 
truly  capitate  and  not  spiked,  never  more  than  from  three  to  five  in  number.  This  inflorescence  differs  very 
much  from  that  of  several  species  in  which  the  spike  is  abbreviated,  either  naturally  or  by  accident,  to  a  few 
flowers. 

The  species  naturally  allied  to  P.  carnosa  are  the  P.  rigida  and  nubigena,  H.  B.  K.,  P.  monanthos,  D'Urv., 
P.  andieola,  Gill.,  P.  pauciflora,  Lam.,  and  P.  barbata,  Forst.,  all  natives  of  the  southern  regions  of  the  globe 
and  of  the  western  hemisphere,  whose  only  representative  in  the  old  world  is  the  present  plant.  If  however 
the  sections  proposed  by  Endlicher  are  adopted,  these  species  will  be  found  to  be  in  several  cases  widely  sepa- 
rated from  one  another.  P.  nubigena,  a  very  beautiful  species,  has  only  two-seeded  capsules  ;  the  seeds  are 
quite  unlike  those  of  carnosa,  being  large,  elliptical-oblong,  black  and  punctated,  with  a  broad  hollow  on  the 
face.  Of  P.  rigida  we  have  specimens  gathered  by  Mr.  Mathews  on  the  Pampas  of  the  Cordillera  in  Peru; 
it  is  perhaps  the  most  singular  species  of  the  genus  in  the  structure  of  its  flowers,  which  are  solitary,  almost 
sessile,  on  very  short  peduncles,  surrounded  by  a  very  broad  sheath  or  spatha  rather  than  bract  at  the  base  ;  the 
calycine  segments  are  lanceolate,  acuminate,  with  a  tuft  of  silky  hairs  at  the  base ;  the  tube  of  the  corolla  is 
twice  as  long  as  the  calyx,  slender,  and  at  least  three  times  longer  in  proportion  to  its  breadth  than  in  any  of  the 
genus  which  I  have  examined  ;  the  filaments  very  long,  straight  and  erect.  M.  Kunth  places  it  in  a  section  "  cap- 
sular loculis  1-spermis,"  but  says  he  has  not  seen  the  fruit.  From  the  small  size  of  the  ovarium  I  could  not  detect 
the  ovules  in  the  flower  I  examined.  P.  monanthos,  though  generally  single-flowered,  has  often  two  or  even 
three  flowers ;  the  capsule  is  four-seeded  ;  it  is  a  very  distinct  species,  common  in  the  Falkland  Islands  and  in 
Fuegia,  singularly  variable  in  size,  and  in  favourable  situations  often  becoming  spuriously  caulescent,  with  stems 
similar  to  those  of  the  P.  arborescens  of  Madeira  ;  the  leaves  are  then  two  inches  long  ;  whilst  in  other  situations, 
as  on  the  exposed  rocks  of  Cape  Horn,  the  whole  plant  resembles  a  densely  tufted  moss,  the  leaves  being  rosu- 
late  and  not  two  lines  long.  Had  I  not  the  opportunity  of  examining  it  in  its  native  state,  I  should  not  have  con- 
sidered several  of  its  varieties  as  belonging  to  one  and  the  same  species.  P.  andieola,  Gill.,  is  a  very  singular 
plant  with  roots  as  thick  and  long  as  the  little  finger,  the  collum  often  much  thicker,  bearing  two  or  more  capi- 
tula  of  very  coriaceous,  lanceolate,  smooth  or  pilose  leaves,  about  1^  inch  long.  The  scapes  are  longer,  often 
twice  as  long  as  the  leaves,  slender  and  hairy,  with  three  to  five  flowers.  The  ovarium  contains  several  ovules,  and  the 
capsule  four  or  more  seeds,  rarely  less,  but  sometimes  only  two.  It  has  been  gathered  on  the  Andes  of  Chili,  both 
by  Dr.  Gillies  and  by  Mr.  Bridges.  P.  pauciflora,  Lam.,  and  P.  barbata,  Forst.,  seem  involved  in  some  confu- 
sion ;  I  have  seen  no  specimens  answering  to  the  description  of  either,  if  they  be  truly  distinct.  In  Mr.  Ander- 
son's collection,  formed  during  Captain  King's  voyage,  there  is  a  species  (P.  imberbis,  MSS.)  agreeing  with 


Campbell's  Islands.']  FLORA  ANTARCTICA.  67 

the  description  given  by  Lamarck,  except  that  the  whole  plant  is  perfectly  glabrous  ;  it  also  is  four-seeded,  and 
the  flowers  vary  from  one  to  three.  These  species  pass  into  other  forms  of  the  genus  :  the  P.  monanthos,  by 
P.  arborescens,  into  the  ovate  and  compressed  spike  of  P.  Psyllium  and  its  allies  ;  and  the  P.  nubigena  through 
P.  tumidu,  Link,  into  the  ordinary  forms  with  cylindrical  elongated  spikes. 

Plantago  is  perhaps  as  universally  distributed  a  genus  as  any  of  dicotyledonous  plants.  In  Arctic  Ame- 
rica Dr.  Richardson  has  gathered  the  P.  major,  L.,  in  lat.  68°  N.,  and  I  have  seen  the  P.  monanthos,  D'Urv.,  in  the 
immediate  neighbourhood  of  Cape  Horn,  in  the  57th  degree  of  south  latitude  :  other  species  not  only  run  along 
the  whole  chain  of  the  Andes,  from  Fuegia  through  Chili,  Peru  and  Colombia,  from  whence  they  are  continued 
along  the  Rocky  mountains,  but  they  also  frequent  the  vast  plains  on  both  sides  of  these  great  barriers.  Under 
the  equator  in  South  America  they  attain  an  altitude  of  13,000  feet,  whence  Prof.  Jameson  has  sent  to  us  a 
species,  gathered  on  Pichincha  in  Colombia.  In  the  continent  of  Europe  they  are  no  less  universally  distributed, 
P.  major,  which  Mr.  Humboldt  brought  from  a  height  of  6000  feet  on  the  Andes  of  Peru,  occurring  in 
Lapland  as  far  north  as  67°,  whilst  in  the  same  country  the  P.  maritima  reaches  the  72nd  degree.  In  Asia  their 
principal  parallel  is  in  Persia,  Cashmere  and  Affghanistan,  where  Mr.  Griffiths  has  collected  numerous  species, 
and  from  whence  they  spread  over  the  great  Siberian  plains  to  Kamtschatka  and  the  borders  of  the  Chinese 
empire.  A  few  species  are  natives  of  Upper  India,  Nepaul,  and  the  Himalayan  mountains.  Only  one  occurs 
in  the  Peninsula  of  India,  the  P.  Uspaghool,  Roxb. ;  this  is  cultivated  in  the  colder  season,  and  Dr.  Ro)Tle  considers 
it  as  probably  a  native  of  Persia.  Hitherto  they  are  unknown  in  the  Malay  peninsula  and  islands,  being  natives 
of  open  and  not  wooded  localities.  For  this  reason  they  are  not  found,  as  far  as  we  know,  in  central  Africa, 
though  several  species  are  natives  of  the  Cape  of  Good  Hope,  and  are  frequent  along  the  southern  shores  of  the 
Mediterranean.  The  various  Atlantic  islands,  as  well  as  the  Mauritius  and  Ceylon  in  the  Indian  Ocean,  and 
those  of  the  Pacific,  Australia  and  New  Zealand,  have  all  representatives  of  the  genus. 

I  have  retained  Mr.  Brown's  name  for  this  species,  the  P.  carnosa  of  Lamarck  being  probably  a  variety  of 
P.  maritima,  L.

Of  this  plant  I  have  seen  neither  flower  nor  fruit,  having  met  with  it  in  a  very  young  state  only.  In  habit, 
size,  and  general  appearance  it  very  closely  resembles  the  R.  cunei/olivs.  It  has  the  large  membranous  stipules 
of  that  plant,  which  are  fimbriated  only  in  age  ;  the  branching  and  size  of  the  two  are  also  the  same  ;  but  in  the 
Auckland  Island  specimens  the  leaves  are  not  decidedly  cuneate  at  the  base,  often  indeed  quite  the  contrary. 
Of  the  true  plant  we  have  many  specimens  from  both  sides  of  America,  from  the  southward  of  the  province  of 
St.  Paul  on  the  east  coast,  and  Valdivia  or.  the  west,  to  the  Straits  of  Magalhaens.  They  vary  but  slightly  in 
the  form  and  length  of  the  leaf,  some  being  attenuated,  others  cordate  at  the  base  ;  always,  in  the  American 
specimens,  broadest  above  the  middle,  and  crisped  rather  than  undulated  at  the  margin.

This  is  a  very  interesting  plant,  belonging  to  an  Australian  genus  of  which  only  two  species  were  previously 
known.  I  have  never  seen  it  alive,  and  am  therefore  unable  to  give  a  coloured  figure  of  the  plant.  In  Tasma- 
nia two  species  grow  at  the  foot  of  Mount  Wellington,  in  a  latitude  however  much  below  that  of  Campbell's 
Island  and  in  a  widely  different  climate.  The  flower  is  smaller  than  that  of  C.  Gunnii,  Lindl.,  to  which,  of  the 
two  other  species,  the  present  is,  on  account  of  the  erect  petals,  most  nearly  allied.  I  am  inclined  to  think  that 
the  glands  on  the  disc  of  the  labellum  will  be  found  to  prove  a  variable  character.  In  one  Tasmanian  species 
they  bear  the  most  striking  resemblance  in  form  and  colour  to  an  ant.

The  leaves  of  this  plant  are  dark  green,  very  coriaceous,  about  4  inches  long  and  3-4  lines  in  breadth,  gra- 
dually attenuated  below  into  a  narrow  sheathing  petiole.  The  scapes  of  the  former  year,  bearing  the  fruit  and 
crowned  with  the  withered,  persistent  perianth,  were  found  along  with  the  young  leaves.  The  capsules  are 
shortly  pedunculate,  pale  brown,  i-|  of  an  inch  long  ;  the  column  considerably  curved,  the  lateral  lobes  each 
with  a  tuft  of  hairs. 

I  have  closely  compared  my  very  indifferent  specimens  of  this  plant  with  the  several  species  of  New  Zea- 
land and  Tasmania,  and  have  no  hesitation  in  describing  it  as  new.

Hab,  Lord  Auckland's  group  ;  on  the  bare  ground  and  growing  in  tufts  of  moss,  Forstera,  &c, 
on  the  bleak  hills. 

Of  this  species  I  possess  only  the  old  scapes,  which  are  about  six  inches  long,  each  bearing  a  solitary  cap- 
sule, with  the  withered  perianth.  The  leaves  I  have  never  seen,  but  there  are  traces  of  sheaths  or  leaves  on 
the  scape,  and  of  a  larger  one,  probably  a  bractea,  below  the  flower.  The  capsule  is  turgid,  elliptical-obovate, 
erect,  about  half  an  inch  long  and  quite  glabrous.  The  leaflets  of  the  perianth  are  rather  shorter  than  the 
capsule  and  strongly  nerved,  as  is  the  labellum,  which  is  rounded  at  the  lower  extremity,  with  a  short  apiculus. 
The  anther  is  inserted  a  little  below  the  apex  of  the  column. 

I  am  very  uncertain  as  to  the  genus  of  this  plant ;  it  differs  from  any  with  which  I  am  acquainted ;  yet  I 
am  unwilling,  in  the  absence  of  better  specimens,  to  constitute  a  new  one  of  it.  In  the  petaloid,  very  distinct 
lateral  lobes  of  the  column,  which  is  3-cleft 'nearly  to  the  base,  it  shows  some  analogy  to  Diuris,  and  in  the  ter- 
minal anther  to  the  group  which  includes  Caladenia  and  many  other  New  Holland  Orchidete.  The  regular  and 
nearly  equal  leaflets  of  the  perianth,  to  which  the  labellum  is  very  similar  in  form  and  structure,  induce  me  to 
retain  it  among  Thelymitra.  It  is  further  undoubtedly  nearly  allied  to  a  plant  included  by  Mr.  Gunn  under  the 
genus  Macdonaldia  (vid.  Lindl.  Swan  River  Botany,  p.  50.  no.  217,  and  Gen.  and  Sp.  Orchid,  p.  385),  which 
contains  two  Tasmanian  species,  one  M.  Smithiana,  Lindl.  (I.  c.  t.  9.  B.),  in  which  the  column  is  undivided  or 
obliquely  trifid  or  three-lobed ;  the  rounded  anther  is  situated  below  the  apex  of  the  column,  on  its  inner  face, 
and  is  villous  ;  in  the  colour  and  appearance  also  of  the  plant,  and  in  the  shape  of  the  leaflets  of  the  perianth, 
it  differs  from  Thelymitra.  The  other  species,  M.  cyanea,  Lindl.,  very  much  resembles  the  more  ordinary  forms 
of  Thelymitra  in  size,  habit,  colour,  and  in  the  shape  of  the  perianth  ;  in  the  more  terminal  acute  anther,  and  in 
the  lateral  lobes  of  the  column  being  produced  upwards  beyond  the  anther  and  bifid  at  the  apex,  it  agrees  with 
the  T.  ?  uniflora.

This  apparently  belongs  to  the  genus  Caladenia,  but  it  is  in  a  very  young  state,  and  the  glands  on  the 
labellum  are  probably  undeveloped.  The  roots  are  small,  oblong  tubers,  connected  by  a  terete  cauliculus.  Leaves 
i-2  inches  long.  The  only  flowers  I  possess  are  just  emerging  from  a  large  cucullate  bractea ;  they  are  of  a 
pale  flesh-colour  mixed  with  yellow.

What  I  take  to  be  the  leaves  of  this  plant  (for  though  growing  along  with  the  scapes  they  were  not 
attached  to  them)  are  solitary  or  rarely  two  together,  arising  from  a  short  cauliculus  terminating  in  an 
elongated  tuber  and  throwing  out  stout  horizontal  fibres  from  its  lower  extremity.     The  withered  scapes,  which

bear  solitary  capsules,  are  2-3  inches  long ;  the  capsules  half  an  inch  long,  oblong-turbinate,  obscurely  glandular, 
and  crowned  with  the  reflexed  leaflets  of  the  perianth.  In  one  specimen  the  labellum  was  furnished  with  only 
four  glands  in  two  lines  ;  in  another  they  extended  to  the  middle  with  four  or  six  in  each  series.

I  have  seen  neither  flower  nor  fruit  of  this  plant,  and  only  a  withered  capsule  of  what  I  believe  to  be  Mr. 
Cunningham's  A.  rivularis,  gathered  in  New  Zealand  by  Mr.  Colenso.  The  leaves  of  the  former  vary  very  much  in 
size  and  shape  according  to  their  age  ;  the  younger  ones  are  cordate  or  ovate  and  cordate  at  the  base,  acute  ;  as 
they  grow  older  they  become  orbicular,  deeply  lobed  at  the  petiole,  of  the  same  size  and  texture  and  similarly 
nerved  as  in  the  genus  Acianthus.

The  following  species  I  am  unable  to  refer  to  any  genus,  the  flowers  being  too  imperfectly  developed  for 
a  satisfactory  determination.

Tubers  about  3  lines  long,  similar  to  those  of  Orchis  latifolia,  but  much  smaller  ;  from  these  the  leaf  springs 
at  once,  its  petiole  surrounded  by  a  tubular  cylindrical  sheath.  The  leaf  is  6-8  inches  long,  1-2  lines  wide, 
acute  or  blunt  at  the  apex,  green,  and  of  a  singularly  thick  and  fleshy  texture  when  recent,  coriaceous  w'hen  dry 
and  quite  black.  The  young  scape  is  covered  with  what  appear  sheathing  cucullate  bracts  ;  they  arise  one  from 
the  base  of  each  of  the  flowers  ;  the  latter  are  very  small.

is  split  above ;  the  flower  is  small  and  inclosed  in  two  sheathing  bracts.  This  plant  has  some  points  in  common 
with  Chiloglottis,  Br.,  but  the  leaves  are  not  like  those  of  that  genus.

I  am  unable  to  refer  this  to  any  described  genus  of  Asphodelea,  and  have  adopted  the  name*  in  allusion  to 
the  magnificent  racemes  of  golden-yellow  nowers  which  it  bears.  It  will  rank  near  Anthericum,  L.,  from  which 
it  differs  in  having  only  one  or  at  most  two  ovules  and  in  the  erect  style.  It  is  also  very  nearly  allied  to  Bul- 
binella,  Kunth  (En.  Plant,  vol.  iv.  p.  569),  especially  in  general  appearance;  but  in  that  genus  the  perianth  is 
persistent,  a  character  probably  of  more  importance  than  the  number  of  ovules  or  bearded  filaments,  which  have 
hitherto  been  considered  sufficient  to  distinguish  genera  too  nearly  allied  in  other  respects. 

Perhaps  no  group  of  islands  on  the  surface  of  the  globe,  of  the  same  limited  extent  and  so  perfectly  isolated, 
can  boast  of  three  such  beautiful  plants,  peculiar  to  their  flora,  as  the  Pleurophyllum  speciosum  (Plate  XXII.  & 
XXIII.),  Celmisia  vernicosa  (Plate  XXVI.  &  XXVII.),  and  the  subject  of  the  foregoing  description.  The  last, 
from  its  greater  abundance  and  conspicuous  colour,  is  certainly  the  most  striking  of  the  three,  not  only  giving 
a  feature  to  the  landscape  wherever  it  grows,  but  in  Campbell's  Island  covering  the  swampy  sides  of  the  hills 
in  such  profusion  as  to  be  distinctly  visible  at  the  distance  of  a  full  mile  from  shore.  The  specific  name  I  have 
given  in  compliment  to  Sir  James  Ross,  who,  during  our  two  days'  stay  in  this  island,  brought  to  me, 
amongst  many  other  new  plants,  one  most  luxuriant  specimen  of  this,  having  three  crowns  of  leaves  from  one 
root  and  no  less  than  seven  racemes  of  flowers,  some  of  which  were  bifid  ;  it  was  between  three  and  four  feet 
high ;  I  much  regretted  the  impossibility  of  preserving  it  whole,  and  the  necessity  there  was  of  cutting  it  up 
into  many  fragments.  The  difficulty  of  preserving  specimens  at  all,  in  latitudes  so  constantly  wet  and  stormy,  is 
very  great ;  especially  on  board  ship,  where,  from  the  vicissitudes  of  the  climate,  they  can  rarely  be  exposed  to 
the  air  on  deck  :  the  operation  is  rendered  doubly  tedious,  when,  as  in  the  islands  under  consideration,  the  vege- 
tation is  of  a  very  succulent  and  coriaceous  consistence.  Most  of  my  specimens  required  to  be  changed  daily,  and 
the  papers  to  be  dried  over  a  long  smoke  funnel  which  traversed  Captain  Ross's  cabin,  the  limited  accommodation 
of  our  ships  affording  no  other  place  available  for  this  purpose.  But  for  this  privilege,  constantly  allowed  me 
during  the  voyage,  and  which  to  any  one  less  devoted  than  that  officer  to  the  objects  of  the  expedition  must 
have  proved  an  insupportable  annoyance,  my  collections  would  have  been  small  indeed.  The  present  plant 
was  collected  on  the  15th  of  December  1840,  but  not  fully  dried  when  we  had  reached  the  78th  degree  of  lati- 
tude in  February  1841. 

It  is  very  natural  that  the  great  size  and  luxuriance  of  this  and  several  other  plants  of  the  high  southern 
latitudes  should  excite  surprise.  Arguing  from  those  countries  in  the  northern  hemisphere  which  are  upon  the 
limits  of  terrestrial  vegetation  and  which  have  a  similarly  rigorous  climate,  the  vegetation  of  the  former  might  be 
expected  to  consist  of  small  and  densely  tufted  plants.  This  is  however  not  the  case,  and  I  have  endeavoured  to 
account  for  the  apparent  anomaly  from  the  fact  that  the  higher  southern  regions  enjoy  a  singularly  equable,  though 
to  the  human  constitution  always  inclement  climate.  It  is  further  to  be  remarked,  that  the  Flora,  even  under  these 
circumstances  of  a  peculiar  luxuriance  in  individuals,  is  composed  of  very  few  species  ;  and  again,  that  in  the 
South,  hardly  any  state  of  vegetation  is  met  with  between  that  of  considerable  abundance  and  almost  complete 
sterility,  and  on  ascending  the  mountains  few  or  no  new  forms  occur  :  the  great  mass  of  the  alpine  plants  (even 
on  the  limits  of  perpetual  snow)  being  those  which  inhabit  the  open  lands  at  the  level  of  the  ocean.  The  botany 
of  the  densely  wooded  regions  of  the  southern  islands  of  the  New  Zealand  group  and  of  Fuegia  is  much  more 
meagre,  not  only  than  that  of  similarly  clothed  regions  in  Europe,  but  of  islands  many  degrees  nearer  the  North-

em  Pole  than  these  are  to  the  opposite  one.  Iceland  for  instance,  in  lat.  62°  N.,  proverbially  barren  as  it  is, 
and  upon  which  no  tree,  but  a  few  stunted  birches,  is  to  be  found,  contains  certainly  five  times  as  many  flower- 
ing plants  as  Lord  Auckland's  group  and  Campbell's  Island  together,  whose  rich  vegetation  is  evident  on  their 
being  first  approached  from  sea ;  and  yet  the  numerical  proportion  which  the  two  great  groups  of  flowering 
plants  bear  to  one  another  in  each  country  is  almost  identical.  Kerguelen's  Land  is  on  the  southern  limit  of 
vegetation  in  its  own  longitude,  as  we  may  presume  from  its  containing  only  eighteen  species  of  flowering 
plants  ;  but  these  cover  as  much  of  the  surface  of  the  island  as  the  plants  of  Spitzbergen  do,  and  yet  the  latter 
country  contains  forty-five  species,  though  on  the  verge  of  Arctic  vegetation  and  infinitely  nearer  the  Pole. 
Lastly,  on  Walden  Island  (lat.  S0^°  N.)  we  have  the  last  traces  of  phsenogamic  plants  in  the  northern  hemi- 
sphere, and  in  the  opposite  one  beyond  the  South  Shetlands  (63°  S.)  no  flowering  plants  exist ;  but  whilst  the 
former  islet  boasts  of  ten  species  of  flowering  plants,  the  latter  contains  but  a  solitary  grass. 

The  uniformity  of  the  Flora  at  the  different  levels  in  any  given  island  of  the  South  is  to  be  expected  from 
the  paucity  of  species,  and  we  further  find  that  these  are  spread  over  vast  extents  of  country.  This  is  remark- 
ably the  case  with  the  southern  American  Flora,  where  the  northern  limit  at  which  the  antarctic  Beech  grows 
near  the  sea  is  45°,  from  which  latitude  as  far  as  56°  S.  the  level  of  the  ocean  seems  to  be  its  natural  habitat : 
again,  the  plants  which  form  the  bogs  of  the  Chonos  Archipelago  in  lat.  45°  S.  are  the  same  as  those  of  Cape 
Horn,  and  the  general  features  of  the  vegetation  of  the  two  localities  are  the  same.  In  the  northern  temperate 
regions  a  very  different  state  of  things  will  be  found  to  prevail :  compare  the  Flora  of  the  south  of  France,  in 
the  latitude  of  the  Chonos  Archipelago,  with  that  of  Argyleshire  in  the  parallel  of  Cape  Horn,  and  how  little 
similarity  exists ;  and  this  not  only  because  the  plants  of  France  cannot  bear  the  climate  of  Scotland,  but  be- 
cause new  forms  are  developed  in  the  latter  country,  equally  unsuited  to  the  south  of  France.  Many  parallel 
cases  to  this  might  be  adduced,  all  tending  to  prove  that  there  are  conditions  in  the  physical  geography  of  the 
southern  islands  which  render  them  unfavourable  to  the  production  of  species,  but  which  are  accompanied  with  a 
luxuriant  development  of  such  as  do  exist :  and  further,  that  species  which  form  the  mass  of  the  vegetation 
under  these  conditions  are  such  as  continue  to  be  typical  of  the  Flora  through  many  degrees  of  latitude  whose 
mean  temperature  is  considerably  different. 

The  equable  climate  which  these  countries  now  under  consideration  enjoy,  is  doubtless  mainly  attributable 
to  the  vast  body  of  ocean  surrounding  them ;  and  though  the  want  of  new  species  must  in  a  measure  depend 
on  the  limited  extent  of  surface  for  their  development,  it  is  not  altogether  from  the  want  of  space  that  the  pau- 
city of  new  forms  in  proceeding  to  the  South  is  to  be  accounted  for,  since  in  no  other  part  of  the  globe  can 
sixteen  degrees  of  so  luxuriant  a  Flora  composed  of  so  few  species  be  traversed. 

All  parts  of  antarctic  America  as  it  is  called,  a  name  its  ungenial  climate  alone,  and  not  its  geographical 
position,  warrants,  are  wet,  foggy  and  cold  ;  snow-storms  and  gales  of  wind  prevail  throughout  the  year ;  and  not 
only  on  the  hills,  for  the  atmosphere  seems  so  loaded  with  moisture,  that  a  precipitation  on  the  upper  regions 
is  generally  followed  at  once  by  rain  or  snow  on  the  lower  grounds.  In  the  summer  the  sun  scarcely  exerts 
any  power  without  raising  mists  which  intercept  its  rays.  The  difference  between  the  summer  and  winter  tem- 
perature is  small,  and  the  diurnal  changes  trifling.  The  perennial  hurricanes  which  sweep  the  exposed  surfaces 
of  the  hills  seem  alone  materially  to  check  the  vegetation,  for  even  on  the  mountains  the  plants  of  the  plains 
reappear  wherever  a  shelter  is  afforded.  In  no  part  of  Scotland  does  1700  feet  of  elevation  exist  without  show- 
ing a  material  change  in  the  vegetable  kingdom,  such  a  height  producing  many  subalpine  and  even  alpine 
plants  not  met  with  at  the  level  of  the  ocean  ;  but  though  in  Hermite  Island  the  mountains  attain  that  height, 
there  is  scarcely  a  plant  growing  upon  them  which  does  not  equally  exist  in  the  open  grounds  near  the  sea. 
Nor  is  there  probably  any  country  where  the  prevailing  species,  forming  the  mass  of  the  Flora,  have  such  wide 
ranges  as  in  Antarctic  America. 

From  this  we  may  presume,  that  plants  will  pass  through  many  degrees  of  latitude,  and  consequently  from 


Campbell's  Islands.']  FLORA  ANTARCTICA.  75 

one  climate  to  another,  provided  there  is  no  sudden  change  of  temperature  to  check  their  progress*  ;  that  is  to 
say,  if  in  each  climate  the  difference  between  the  extremes  is  the  same,  small,  and  that  change  slow  ;  and  that 
we  may  expect  the  range  of  individual  species  to  increase  with  the  uniformity  of  the  temperature  throughout 
the  year. 

The  above  observations  have  been  drawn  chiefly  from  a  consideration  of  the  antarctic  American  Flora, 
which  is  the  only  one  sufficiently  investigated  hitherto  for  this  purpose.  The  plants  of  the  Middle  Island  of 
New  Zealand  are  only  known  from  the  collections  of  Banks  and  Solander,  Forster  and  Menzies,  which  were 
made  in  Queen  Charlotte's  Sound  and  Dusky  Bay,  chiefly  in  the  latter  ;  those  of  the  Southern  or  Stewart's 
Island  are  entirely  unknown;  the  Northern  Island  maybe  considered  as  pretty  well  explored,  but  an  aggregate 
of  the  whole  shows  the  Flora  of  New  Zealand  to  be  in  all  probability  the  poorest  of  any  country  of  its  size 
situated  in  the  same  latitude.  Though  this  group  extends  from  lat.  34°  to  the  48th  degree,  the  summers  of  the 
northern  extremity  are  not  scorching,  nor  the  winters,  in  its  southern,  severe.  It  is  true  that  its  high  moun- 
tains have  been  but  partially  explored  ;  but  botanists  have  ascended  them,  as  Mr.  Bidwill,  Dr.  Dieffenbach,  and 
Mr.  Colenso,  in  whose  collections  the  amount  of  new  forms  from  so  considerable  an  altitude  as  that  of  6-10,000 
feet  is  very  trifling,  and  the  species  brought  by  each  person  the  same.  In  the  immediate  neighbourhood  of  Port 
Jackson,  400  species  of  flowering  plants  may  be  easily  collected  in  four  days'  excursions ;  in  the  same  time 
scarcely  half  that  number  would  be  detected  in  the  Bay  of  Islands,  very  little  to  the  southward  of  Sydney  in 
latitude ;  and  on  extending  the  journeys  further  in  each  country  to  thirty  or  forty  miles,  the  disproportion  in- 
creases. A  remarkable  uniformity  in  the  Flora  pervades  all  the  South  Sea  Islands,  also  accompanied  with  a 
singularly  equable  temperature.  The  change  which  an  elevation  of  10,000  feet  produces  in  the  Flora  of  Colom- 
bia is  complete,  and  the  number  of  species  inhabiting  the  plains  of  Quito  much  exceeds  that  in  the  low  forests 
of  the  west  coast  of  America,  in  the  same  parallel ;  but  though  the  volcanic  islands  of  the  Sandwich  group 
attain  a  greater  elevation  than  this,  there  is  nosuch  development  of  new  species  at  the  upper  level. 

Amongst  the  many  branches  of  inquiry  into  which  the  science  of  Botanical  Geography  divides  itself,  that 
which  concerns  the  comparative  richness  in  species  of  countries  similarly  situated  is  a  highly  interesting  one.  An 
exuberant  vegetation  we  find  not  to  be  necessarily  the  index  of  an  extensive  flora,  nor  is  it  in  the  most  densely 
clothed  spots  that  the  greatest  variety  of  forms  is  to  be  met  with,  but  very  often  the  contrary.  Few  lands  we 
have  seen  are  so  deceptive  in  this  respect  as  New  Zealand  and  Tierra  del  Fuego ;  and  on  extending  the  inquiry, 
we  further  see  that  the  sandy  plains  of  Australia,  the  Cape  of  Good  Hope,  and  the  campos  of  central  Brazil,  are 
richer  in  species  than  the  more  luxuriant  woods  of  those  or  most  other  countries.

*  A  familiar  instance  of  the  advantage  of  slow  changes  of  temperature  in  enabling  plants  to  endure  trans- 
portation, is  found  in  the  application  of  Mr.  Ward's  glazed  cases  for  transmitting  plants  to  England  through 
different  climates.  One  of  the  main  features  of  his  philosophical  contrivance  is,  that  their  construction  induces  a 
slow  change  of  temperature  in  the  atmosphere  immediately  surrounding  the  plants,  and  prevents  their  suffering 
from  any  sudden  variations.

XXXV.     FUNGI,  L. 

(By  the  Rev.  M.  J.  Berkeley.) 

The  number  of  Fungi  collected  during  the  Expedition  is  very  small,  in  proportion  to  that  of  other  cryptogarnic 
plants,  with  the  exception  of  those  found  in  New  Zealand  and  Van  Diemen's  Land.  In  the  more  southern  locali- 
ties, Fungi  may  naturally  be  expected  to  cease,  sooner  than  Algre,  Lichens,  and  Mosses ;  and  accordingly,  from 
such  localities,  the  amount  of  species  is  trifling  indeed.  Even  where  the  degree  of  cold  is  not  sufficient  to  prevent 
the  growth  of  Fungi,  their  fructification  is  materially  affected ;  and  thus,  in  the  higher  forms,  the  hymenium  will 
frequently  be  found  barren ;  while,  in  some  hypoga;ous  species,  transformations  of  the  sporophores  themselves  take 
place,  causing  the  fructifying  mass  to  assume  a  very  anomalous  appearance.  Some  species  indeed,  as  Pilobolus 
crystallinus  and  Hydropliora  stercorea,  seem  to  flourish  most  in  the  frosty  nights  of  autumn,  and  the  species  of  the 
genus  Chatonypha  and  Lanosa  nivalis  thrive  either  beneath  or  upon  the  surface  of  the  snow ;  but  I  know  of  uo  other 
exceptions  to  the  more  general  habit  of  these  species,  and  in  these  cases,  the  temperature  either  does  not  descend 
below  the  freezing  point,  or,  as  in  the  case  of  the  CJiatonypha,  vegetation  takes  place  only  when  the  surface  of  the 
snow  is  just  melting  under  the  influence  of  the  sun. 

Amongst  the  more  northern  islands  visited  by  the  Expedition  it  is  probable  that  some  interesting  forms,  had 
time  allowed,  would  have  rewarded  further  research ;  though,  indeed,  constant  attention  was  directed,  even  to  the 
obscurest  forms  of  vegetation,  wherever  circumstances  woidd  permit.  As  it  is,  there  is  a  considerable  number  of 
new  species  to  describe,  and  some  of  them  possess  much  interest,  especially  a  new  Cyttaria  from  Cape  Horn,  the 
specimens  of  which  are  so  numerous  as  to  afford  an  excellent  opportunity  of  examining  the  structure  of  this  curious 
genus ;  which,  like  Fodisoma  and  Gymnosporangium,  which  infest  certain  species  of  Juniper,  developes  itself  on  the 
living  branchlets  of  the  deciduous-leaved  Beech.  Some  of  the  species,  like  those  of  other  Cryptogams,  are  identical 
with  plants  of  the  Northern  Hemisphere ;  and  this  is  especially  observable  in  New  Zealand,  where  the  identity  is 
not  confined  to  those  families  in  which  it  is  more  usual.

the  same  species  (vid.  supra).  It  is  worthy  of  observation,  that  the  sporidia  exhibit  these  changes  whilst  still  co- 
lourless. Diplodia  presents  a  somewhat  analogous  case  to  this,  septa  being  sometimes  formed  in  that  genus  after 
the  spores  have  acquired  their  colour.

A  very  pretty  species,  remarkable  for  the  small  number  of  fructifying  cells  and  the  dark  Une  enclosing  the  stroma,

sporidia  are  almost  of  the  same  shape  with  those  figured  by  Corda,  in  Eliytisma  Eugeniacearum  ;  when  young  they 
are  filled  with  distinct  granules  which  become  less  evident  as  they  are  more  developed.  In  age  the  stroma  com- 
pletely decays  and  falls  out,  leaving  a  scutellum  surrounded  by  the  cuticle.  This  follows  from  the  dark  fine  indi- 
cating a  harder  substance  than  that  of  the  stroma,  which  is  not  always  externally  risible,  but  will  be  found  on  making 
a  vertical  section.

of  only  a  single  layer  of  cells,  occasionally  appears,  no  trace  of  this  is  seen  on  the  sides  of  the  cavities  distinct  from 
the  neighbouring  tissue.  The  specimens  procured  are  not  numerous,  in  no  instance  does  more  than  one  individual 
appear  upon  a  single  leaf,  the  latter  being  probably  of  too  small  a  size  to  support  more  than  a  solitary  stroma  of  such 
high  organization.  Like  some  other  species  indicated  by  Montague  in  his  '  Fungi  of  Cuba,'  this  is  probably  originally 
produced  between  the  layers  of  the  cuticle,  for  some  of  the  latter  is  found  beneath  the  stroma.  The  cells  of  the  stroma 
pass  at  the  base  iuto  a  mass  of  reticulated  filaments,  without  any  membrane  being  attached  to  the  meshes.

In  some  leaves  the  spots  are  very  numerous,  in  others  they  are  but  few  and  of  a  larger  size.  The  species  is 
most  allied  to  the  D.  amphimelana,  Mont.,  and  D.  ZoUingeri,  B.  and  M.,  although  not  very  near  either ;  it  exhibits, 
also,  some  affinity  with  D.  granulosa,  Hook,  et  Am.  Externally  it  strongly  resembles  the  punctiform  variety  of 
Rhytisma  salicinum.     The  spots  are  of  a  shining  black,  and  are  very  minutely  granulated  under  a  lens.

*  The  remark  in  inverted  commas  was  made  by  Dr.  Harvey. — The  division  of  the  spores  of  Fucacea  was  observed 
while  examining  the  2)'  Urvillea  utilis  in  a  fresh  state,  when  they  were  considered  as  tetraspores,  and  again  by  Dr. 
Montagne  and  by  myself,  in  dried  specimens  of  XJphophora.  More  recently,  and  since  the  above  was  written,  the 
interesting  paper  of  MM.  Decaisne  and  Thuret  has  appeared,  in  the  'A/males  des  Sc.  Nat.'  (Series  3.  vol.  iii.  p.  1.) 
It  is  there  shown  that  this  structure  exists  in  five  species  of  Fucus  abundant  on  our  shores ;  F.  nodosus,  serratus, 
vesiculosus,  canaliculatus  and  tuberculatus  :  also  in  Himanthalia,  which  I  have  elsewhere  allied  to  V  Urvillea  (London 
Journ.  of  Botany,  vol.  ii.  p.  325),  and  the  mode  of  division  in  the  original  spores  is  excellently  followed  and  illus- 
trated, as  also  their  germination,  a  most  important  point.  I  cannot  omit  here  an  allusion  to  two  of  the  most  re- 
markable recent  discoveries  in  modern  Botanical  Science,  made  by  those  observers,  and  published  in  the  same  paper  : 
— that  of  organs,  in  every  respect  analogous  to  the  antheridia  of  mosses  (of  whose  nature  my  coadjutor,  Mr.  Harvev, 
had  formed  the  same  idea),  existing  in  all  the  above-mentioned  Fuci;  and  these  antheridia  being  wholly  filled,  be- 
fore bursting,  with  bodies  endowed  with  rapid  motion  and  apparent  volition,  and  which,  though  thus  proved  to 
be  truly  of  vegetable  origin,  have  hitherto  been  ranked  in  the  animal  kingdom.  I  am  indebted  to  the  friendship 
of  M.  Decaisne  for  a  demonstration  of  these  curious  phenomena  in  living  Alga',  and  for  the  original  drawings  from 
which  the  plates  that  accompany  his  interesting  paper  in  the  'Annates '  are  executed. — J.  D.  H.

We  defer  our  remarks  on  this  plant,  and  on  the  genus  Desmarestia  in  general,  to  a  future  portion  of  this  work. 
The  present  species  was  found  abundantly  at  Christinas  Harbour  in  Kerguelen's  Land,  Berkeley  Sound,  and  Port 
William  in  the  Falkland  Islands,  and  at  Cape  Horn ;  and  will,  therefore,  come  more  properly  along  with  some  new 
species  into  the  flora  of  those  regions. 

7.  DICTYOSIPHON,  Grev. 

Obs.  The  following  species  differs  in  some  points  from  this  genus,  being  of  a  thicker  substance  and  denser 
structure,  and  with  the  walls  composed  of  a  greater  number  of  rows  of  cells,  which  are  themselves  very  much  smaller. 
The  surface  of  the  frond  is,  therefore,  not  in  the  least  reticulated.  Still  the  fructification  is  so  identical  with  that  of 
Dictyosiphon,  that  we  are  unwilling  to  separate  it,  especially  since  the  habit  is  not  dissimilar.

A  single  specimen  of  this  plant,  which  seems  to  be  common  in  Lord  Auckland's  group,  was  picked  up  by 
Dr.  Lyall  in  Berkeley  Sound,  Falkland  Islands.  It  was  more  bushy  than  the  Auckland  Island  specimen,  with  longer 
branches  ;  the  outline  is  ovate  and  not  lanceolate ;  the  main  branches  chiefly  are  crowded  and  fasciculate,  the  minor 
ones  of  the  ramuli  more  frequently  distichous,  often  opposite  and  rather  patent.  In  fact,  part  of  the  plant  exhibits  the 
bushy  aspect  of  Dictyosiphon  and  part  resembles  Striaria ;  the  scattered  fruit  distinguishing  it  from  the  latter  genus.

These  specimens  differ  sbghtly  from  the  European  form  of  the  species,  in  having  the  constrictions  less  obvious 
and  at  much  wider  intervals.  In  some  individuals  scarcely  any  constriction  occurs,  and  then  it  is  not  easy  at  first 
sight  to  distinguish  them  from  a  common  state  of  Asperococcus  ecliinatus.  In  others,  again,  they  are  evident,  and 
microscopical  examination  proves  that  they  do  not  belong  to  Asperococcus.  At  the  Falkland  Islands  this  plant  was 
also  found,  and  the  specimens  from  that  locality  are  identical  with  the  common  European  appearance.

Obs.  This  genus  differs  from  Asperococcus  in  having  its  fructification  spread  over  the  entire  surface,  as  in 
Chorda,  and  not  confined  to  distinct  sori ;  and  from  the  latter  in  being  destitute  of  septa,  and  in  possessing  innumer- 
able pale  depressions,  composed  of  radiating  filaments  with  very  short  coloured  joints,  emitting  from  their  apices 
tufts  of  colourless,  long,  jointed,  byssoid  fibres.  These  appear  afterwards  to  fall  away,  leaving  depressions  and  often 
punctures  of  the  membrane  in  their  place.  The  tufts  of  arachnoid  fibres  do  not  expand  well  after  having  been 
dried,  though  they  may  always  be  found  in  the  damaged  state,  by  carefully  scraping  away  the  surface  of  the  frond.

This  species  is  of  so  large  a  size,  such  considerable  diameter  of  filament,  is  so  opaque  and  withal  exhibits  such 
sbght  external  appearance  of  articulation,  that  it  seems  at  first  sight,  to  possess  considerable  affinity  with  R/todomela, 
and  further  bears  a  strong  resemblance  to  R.  subfusea,  which  it  exceeds  in  size,  while  agreeing  with  it  in  ramification. 
A  careful  examination,  however,  induces  us  to  place  it  in  Polysiphonia,  and  in  the  section  to  which  P .  fruticulosa

belongs.  The  internal  structure  of  the  stem  is  similar  to  that  of  P.fruticulosa,  but  there  are  fewer  radiating  fibres, 
and  is  quite  unlike  that  of  Mod.  subfusca.  There  are  two  varieties,  one  more  robust,  flexuous  and  densely  branched 
than  the  other ;  but  they  do  not  appear  specifically  distinct.  Both  bear  capsidar  fruit,  of  a  peculiarly  clustered 
character,  different  from  that  of  any  other  Polysiphonia,  and  we  regard  it  as  the  principal  distinction  on  which  the 
species  rests.  The  capsules  are  farther  remarkable  for  their  minuteness  in  proportion  to  the  plant  producing  them. 
Their  number,  however,  compensates  for  size,  thirty  or  forty  occupying  a  space  not  greater  than  that  of  a  capsule 
of  the  dimensions  usual  in  this  genus.

Slightly  variable  in  some  minor  characters,  yet  a  distinctly  marked  and  easily  recognized  species.  Main  branches 
irregular,  being  imperfectly  dichotomous  or  having  a  simple  stem  furnished  with  lateral  branches.  The  most  striking 
specific  character  consists  in  the  dichotomously  multifid  fan-like  ramuli,  which  are  set  rather  laxly  along  the  branches. 
We  have  not  seen  ceramidia ;  several  of  our  specimens  produce  stichidia,  of  the  shape  described  by  Montagne  ;  but 
the  sphaerospores  are  in  a  double  and  occasionally  a  triple  row,  as  in  Basya.  In  one  individual,  the  ceramidia  are 
replaced  (by  disease)  with  a  cluster  of  sphasrical  bodies,  forming  a  mass  which  resembles  the  favella  of  a  Callitham- 
nion,  and,  from  which,  fascicles  of  ramuli  are  given  off  in  a  proliferous  manner.  These  call  to  mind  the  capsules  of 
P.  botryocarpa,  and  though  their  structure  be  very  irregular,  they  suggest  a  doubt  whether  the  remarkable  fructifi- 
cation of  the  latter  plant  is  not  abnormal.

such  individuals  are  from  -i-l  inch  high.  But,  when  larger,  lateral  branches  begin  to  be  developed,  in  every  respect

It  it  exceedingly  difficidt  to  um'avel  the  synonymy  of  the  species  belonging  to  this  genus.  The  name  of 
Chamitis  was  applied  to  A.  filamentosa,  Lam.,  and  A.  trifurcata,  Hook.,  by  Gaertner  in  1788,  adopted  from  the 
MSS.  of  Banks  and  Solander.  These  voyagers  discovered  a  third  species,  Chauitis  trifurcata,  a  name  which  Gaertner 
has  accidentally  affixed  to  his  plate  of  A.  tricuspidata. 

The  Azorella  caspitosa,  according  to  a  statement  made  by  Cavanilles,  1.  c,  was  probably  first  detected  by 
Commerson ;  the  specimens  figured  by  the  author  just  quoted  are  from  the  Cordillera  of  Chili,  and  Mr.  Darwin 
having  gathered  it  at  Port  Desire,  and  Capt.  King  at  Cape  Fail-weather,  it  is  probably  a  very  general  plant  throughout 
the  southern  parts  of  Patagonia.

The  genus  Azorella  was  founded  upon  this  species  and  is  probably  a  name  of  Commerson5 s ;  for  Lamarck,  who 
adopted  it  in  17 S3,  remarks  that,  not  knowing  the  fnut,  he  cannot  see  how  it  differs  from  Hydrocotyle. 

The  present  is  a  very  common  plant  throughout  Fuegia  and  the  Falkland  Islands.  Gaertner  mentions  having 
examined  specimens  in  the  Bauksian  Herbarium,  with  three  carpels.

Rather  a  scarce  plant  and  perfectly  distinct  from  the  following,  with  which  it  has  been  strangely  confounded, 
partly  because  Gaertner  inadvertently  applied  the  name  of  A.  tricuspidata  to  his  figure  of  Banks'  A.  trifurcata,  and 
partly  owing  to  the  confusion  in  wliich  the  whole  group  to  which  it  belongs  has  long  been  involved,  and  the  refer- 
ence of  many  different  umbelliferous  plants  with  a  tufted  habit  and  simple  umbels,  by  Lamarck,  to  the  Bolax  glebaria

Found  at  all  elevations,  both  in  Fuegia  and  in  the  Falkland  Islands,  and  so  much  resembling  Coloban  tints 
subulatus,  that  the  two  plants  have  often  been  taken  for  each  other  and  for  the  Mniarum  fascicidatum,  Forst.,  a  New 
Holland  and  New  Zealand  plant,  which  is  hence  erroneously  described  as  being  also  a  native  of  the  Strait  of 
Magalhaens.  The  fruit  of  this  species  certainly  differs  from  that  of  the  two  former,  and  they,  again,  from  the  carpels 
of  A.  ecespitosa  and  the  following ;  I  have,  however,  brought  them  all  under  one  genus,  feeling  assured  that  the 
details  of  the  form  of  the  mericarps  do  not  afford  the  important  characters  in  this  group  that  they  do  in  some 
other  UmbellifertB.

The  fruit  of  this  plant  is  so  dorsally  compressed  and  contracted  at  the  sutures,  as  almost  to  justify  its  being 
removed  from  this  genus  and  even  group.  The  calycine  teeth  and  the  styles  are  rather  longer  than  is  usual  in 
Azorella ;  still,  as  mentioned  above,  the  fruits  of  almost  all  the  species  that  I  have  examined  differ  so  widely  from 
one  another,  that  to  separate  this  or  either  of  the  former  would  involve  the  complete  dismemberment  of  a  genus,  of 
which  all  the  species,  except  the  following,  are  very  closely  allied. 

Azorella  Selago  is  the  most  abundant  plant  in  Kerguelen's  Land,  covering  the  rocky  ground  close  to  the  sea 
with  brown  masses  many  feet  in  extent,  and  often  so  soft  that  the  traveller  plunges  into  or  through  them  up  to  the 
middle.      Like  the  curious  Bolax  glebaria  of  the  Falkland  Islands,  the  living  part  of  the  plant  forms  a  crust  over  a

vast  mound  of  debris,  the  decaying  remains  of  former  years'  growth,  through  which  the  roots  descend  into  the 
ground.  In  Fuegia  this  plant  is  much  scarcer,  and  only  occurs  on  the  mountains  in  small  tufts.  I  have  also  seen

This  plant  differs  so  materially  in  habit  from  those  described  above,  that  I  have  placed  it  in  a  separate  section

it  was  rightly  referred  by  D'Urville;  it  also  very  much  resembles  the  Fozoa  reniformis,  in  Part  1.  p.  15.  t.  xi.  where

I  have  endeavoured  to  unravel  the  synonymy  of  this  highly  curious  and  now  well-known  plant,  but  cannot 
ascertain  what  are  the  various  species  figured  by  Lamarck  and  partially  described  by  Poiret,  both  these  writers

286  FLORA  ANTARCTICA.  [Fuegia,  the 

Long  before  the  Falkland  Islands  were  colonized  from  Britain,  the  present  plant  had  excited  considerable 
curiosity  by  the  very  remarkable  mode  of  growth  it  there  assumes  and  its  forming  a  feature  in  the  landscape  that 
strikes  the  most  casual  observer.  Now  that  these  islands  have  been  annexed  formally  to  the  British  dominions, 
the  Bolax  or  Balsam-bog  is  a  production  of  still  greater  general  interest.  In  whatever  portion  of  this  country  the 
voyager  may  land,  he  cannot  proceed  far  along  the  beach  without  entering  groves  of  Tussac,  whose  leaves  often  wave 
over  his  head  ;  nor  turn  his  steps  inland  without  seeing,  scattered  over  the  ground,  huge,  perfectly  hemispherical 
hillocks  of  a  pale  and  dirty  yellow  green  colour  and  uniform  surface,  so  hard  that  one  may  break  the  knuckles  on 
them.  If  the  day  be  warm,  a  faint  aromatic  smell  is  perceived  in  their  neighbourhood  and  drops  or  tears  of  a  viscid 
white  gum  flow  from  various  parts  of  these  vegetable  hillocks.  They  stand  apart  from  one  another,  varying  from  2-4 
feet  in  height,  and  though  often  hemispherical,  are,  at  times,  much  broader  than  high,  and  even  eight  or  ten  feet 
long.  The  very  old  ones  begin  to  decay  near  the  ground,  where  a  crumbling  away  commences  all  round,  and  having 
but  a  narrow  attachment,  they  resemble  immense  balls  or  spheres  laid  upon  the  earth.  Upon  close  examination,  each 
mass  is  found  to  be  herbaceous  throughout,  the  outer  coat  formed  of  innumerable  little  shoots  rising  to  the  same 
height,  covered  with  imbricating  leaves,  and  so  densely  packed  that  it  is  even  difficult  to  cut  out  a  portion  with  a 
knife,  while  the  surface  is  of  such  uniformity  that  lichens  sometimes  spread  over  it,  and  other  plants  vegetate  on  its 
surface  in  the  occasional  holes  or  decayed  places.  If,  at  a  very  early  period,  a  young  plant  of  the  Bolax  be  removed 
and  examined,  the  origin  of  these  great  balls  may  be  traced ;  for  each  of  them,  of  whatever  size,  is  the  product  of  a 
single  seed,  and  the  result  of  many,  perhaps  hundreds  of  years'  growth.  In  a  young  state  the  plant  consists  of  a  very 
long  slender  perpendicular  root,  like  a  whip-lash,  that  penetrates  the  soil.  At  its  summit  are  borne  two  or  three  small, 
branching  stems,  each  densely  covered  for  its  whole  length  with  sheathing  leaves.  As  the  individual  increases  in 
size,  the  branches  divide  more  and  more,  radiating  regularly  from  the  rooting  centre,  instead  of  prolonging  rapidly ; 
these  send  out  lateral  short  shoots  from  their  apices,  and  in  such  numbers  that  the  mass  is  rendered  very  dense,  and 
by  the  time  the  plant  has  gained  the  diameter  of  a  foot,  it  is  quite  smooth  and  convex  on  the  surface.  The  solitary 
root  has  become  evidently  insufficient  for  the  wants  of  the  mass  of  individuals,  which  are  nourished  by  fibrous 
radicles,  proceeding  from  below  the  leaves,  and  deriving  nutriment  from  the  quantity  of  vegetable  matter  which  the 
decayed  foliage  of  the  lower  part  of  the  steins  and  older  branches  affords. 

The  B.  ghbaria  yields  a  gum,  which  is  white  when  oozing  from  the  wounded  stems  and  leaves,  but  soon  turns 
red-brown  on  drying ;  it  has  been  used  as  an  application  to  cuts  and  other  lesions  with  apparent  effect,  and  for  the 
cure  of  Gonorrhoea,  with  more  doubtful  success. 

From  Mr.  Webster's  account  it  is  abundant  in  Staten  Land,  and  is,  I  believe,  also  found  in  perfection  in 
Patagonia.     In  Hermite  Island  it  never  assumes  the  form  it  docs  in  the  Falklands.

taken  to  be  correct,  the  branching  of  this  plant  is  trichotomous,  for  the  three  peduncles,  bearing  each  a  simple 
umbel,  arise  from  one  point,  the  terminal  or  central  branch  flowers  first,  and  therefore  cannot  be  considered  as  the 
intermediate  division  of  a  compound  umbel,  in  which  the  external  rays  always  open  before  those  nearer  the  axis : 
the  structure  of  the  inflorescence  is  similar  to  Astrantia  (vid.  Brown  in  Linn.  Trans,  vol.  xi.  p.  92). 

The  Huanaca  Cavanillesii  was  first  discovered  at  Port  Desire  by  Nee,  who  accompanied  the  Spanish  voyager 
Malaspinas ;  and  again  by  Mr.  Darwin  in  the  same  locality.

Apparently  our  common  Celery,  and  even  more  abundant  in  the  countries  enumerated  above,  than  in  Europe. 
Except  its  often  assuming  a  prostrate  habit  in  the  Antarctic  regions,  I  perceive  no  external  difference  from  the 
northern  state  of  the  plant ;  its  properties  are,  however,  very  unlike,  for  the  wild  Antarctic  specimens  are  always 
mild  and  wholesome,  insomuch  that  the  officers  and  crews  of  the  Expedition  made  constant  use  of  it,  both  raw  and 
boiled  like  spinach.  This  absence  of  all  injurious  or  even  disagreeable  properties  may  perhaps  be  owing,  in  some 
degree,  to  the  want  of  the  direct  rays  of  the  sun,  which  is  seldom  bright  and  clear,  and  often  invisible  for  many 
days  in  the  height  of  summer  in  these  far  southern  regions.  If  this  be  so,  we  have  a  natural  cause  producing  the 
same  results  which  the  skdl  of  the  gardener  effects  in  our  more  favoured  climate. 

The  Apium  graveolens  is  also  a  native  of  Tasmania  and  the  Cape  of  Good  Hope..

Ottoa,  H.  B.  K.,  and  (Enanthe,  Lamk.;  indeed  it  is  to  the  latter  genus  alone  that  the  present  is  allied  in  the  fishdose 
leaves,  while  it  resembles  the  former  in  the  septate  structure  of  the  foliage,  and  has  other  points  of  affinity  in  the 
rank  smell  and  taste,  aquatic  habit,  vittate  mericarps,  and  the  longitudinal  ridge  iu  front  of  the  seed  itself. 

The  Falkland  Island  specimens  are  very  constant  in  the  form  of  their  leaves ;  those  from  the  Plate  River,  on 
the  other  hand,  are  exceedingly  variable  both  in  size  and  foliage,  the  latter  sometimes  measuring  six  inches  long 
and  expanding  into  a  plane,  linear-lanceolate,  obtuse  lamina. 

In  both  Americas  the  Crantzia  is  confined  to  the  east  coast ;  in  the  northern  hemisphere  ranging  from  30°  to

Hab.  Falkland  Islands ;  in  grassy  places,  abundant ;  Pi  Urville,  J.  D.  H. 

This,  .which  is  rather  a  variable  plant,  appears  to  be  altogether  identical  with  that  gathered  on  the  Andes  by 
Humboldt  and  Bonpland,  and  more  lately  by  Linden,  near  the  snow  line  on  Orizaba,  in  Mexico,  by  Goudot  in  New 
Grenada,  at  the  limit  of  perpetual  snow,  by  Professor  Jameson  at  an  altitude  of  14,700  feet,  on  the  Andes  of  Quito, 
and  by  Mr.  M'Lean  in  Peru :  for  I  refer  all  the  Caldasia  of  these  collectors  to  the  present  species,  which  there,  as 
in  the  Falklands,  has  the  leaves  more  or  less  cut,  their  segments  crowded  or  lax,  and  all  the  parts  copiously  hairy 
or  nearly  smooth.  It  is  very  singular  that  it  should  not  have  been  hitherto  found  at  any  intermediate  station 
between  Peru  and  the  Falkland  Islands,  where  it  grows  as  constantly  at  the  level  of  the  sea,  as  at  the  limit  of 
eternal  snow  on  the  Cordillera  under  the  line.  Assuming  15,000  feet  to  be  its  station  under  the  equator,  it  has 
descended  that  number  of  feet  in  52  degrees,  or  nearly  300  feet  for  every  degree  of  latitude.  The  labours  of  Hum- 
boldt and  of  Professor  Jameson,  who  have  determined  with  great  accuracy  the  zones  of  elevation  which  many  plants  of 
the  Cordillera  affect,  are  daily  proving  of  increased  value  j  and  now  that  many  of  the  same  species  are  fcmnd  at  far 
less  elevations  and  even  on  the  shores  of  the  ocean  in  lower  latitudes,  they  afford  most  essential  data  for  comparing 
the  effects  of  latitude  with  those  of  elevation  upon  vegetation,  which,  from  various  causes,  are  not  what  the  difference 
of  temperature  would  indicate.  Thus,  the  parallel  of  the  Straits  of  Magalhaens  appears  to  be  the  point  where 
plants,  inhabiting  the  altitude  of  15,000  feet  under  the  equator,  meet  the  ocean  ;  but  the  snow-line  itself  is  there 
4,000  feet  higher  and  does  not  descend  to  that  level  for  eight  degrees  further  south.

As  the  genus  Myzodendron  is  perhaps  the  most  interesting,  in  a  structural  point  of  view,  of  any  cokected

following  species.

290  FLOEA  ANTARCTICA.  Fuegia,  the 

iufested  by  this  genus,  will  be  described  voider  M.  bracliystacltyum,  where  only  I  have  been  able  to  watch  that 
opei'ation.  The  present  species  follows  the  same  course,  I  presume,  judging  from  the  appearance  of  a  fully  established 
parasite. 

The  anatomy  of  the  stem  and  branches  of  M.  punctnlatum  not  only  differs  widely  from  that  of  M.  brachystacliyum, 
but  of  most  other  Dicotyledonous  plants ;  its  axis  being  wholly  occupied  by  very  dense  fibres  apparently  of  woody 
tissue,  and  presenting  there  no  trace  of  the  cellular  tissue,  which  is  constantly  present  in  such  plants  as  increase 
by  annual  layers.  The  bark  of  the  young  branches  is  thick  and  spongy  and  a  transverse  section  presents  the  following 
structure.  1st.  A  very  delicate  but  firni  cuticle,  striated  externally  with  lines  of  extreme  tenuity.  2nd.  Immedi- 
ately beneath  this  is  a  cellular  tissue  forming  the  epiphlceum.  3rd.  A  series  of  cavities  occupy  the  circumference 
of  the  bark ;  they  are  what  have  been  called  in  other  plants  respiratory  cavities,  and  correspond  each  to  one  of  the 
tubercles  on  the  surface  of  the  stem  ;  the  cuticle  is  depressed  immediately  over  the  centre,  where  a  very  evident 
stoma  is  situated.  4th.  The  cellular  tissue  forming  the  mesophloeum  is  hexagonal,  thick-sided,  and  very  often 
full  of  a  green  chromule.  I  have  seen  no  raphides  in  any  of  the  species.  5th.  The  liber  contains  a  series  of 
isolated  bundles  of  delicate  fibres  (Plate  CVII./.  9.  a.)  frequently,  for  some  part  of  their  length,  protected  by  cells 
of  great  density,  such  as  may  be  seen  in  the  Lime  and  Antarctic  Fayi.  The  proportion  of  fibrous  tissue  to  the 
thickness  of  the  bark  is  very  small,  and  the  fibres  composing  it  exceedingly  slender.  Between  tliis  and  the  sca- 
lariform  tissue  lies  a  very  thick  layer  of  loose  hexagonal  cellular  tissue,  formed  of  membranous  utricles,  which  are 
discoloured  and  compressed  immediately  around  the  annual  layers.  6th.  The  greater  portion  of  the  old  stem,  all 
that  part  which,  in  Dicotyledonous  wood,  is  usually  occupied  by  pleurenchyma,  is  here  wholly,  or  nearly,  formed 
of  elongated  variously  marked  tubes,  of  almost  equal  diameter,  they  are  white  and  diaphanous,  dotted,  ringed,  trans- 
versely barred,  or  contain  a  spiral  vessel,  more  or  less  broken  (Plate  CVII./.  8,9  and  10,  c).  I  have  not 
observed  simple  or  thick-sided  tubes  of  pleurenchyma,  true  tracheae,  or  bothrenehyma,  either  in  the  inner  portion 
of  each  annual  layer,  or  in  the  usual  position  of  the  medullary  sheath.  7th.  The  axis  of  the  stem  is  formed  wholly  of 
a  dense  tissue  of  woody  fibres  (Plate  CVII.  Jigs.  8,  9  and  10  b.)  the  tubes  all  very  small,  inseparable,  even  after  long 
maceration,  and  their  walls  so  thick  that  it  is  difficult  to  trace  the  dark  longitudinal  liue  which  indicates  their 
cavity  which  contains  gramdes,  though  a  dot  in  the  centre  of  the  transverse  section  of  each  fibre  is  very  evident. 
This  axis  suffers  no  change  after  the  first  year's  growth,  and  at  that  period  may  be  seen  to  project  wedge-shaped 
plates  in  the  manner  of  medullary  rays,  into  the  scalariform  tissue  which  it  hardly  divides. 

The  stems  of  this  plant  are,  though  hard  in  texture,  very  brittle,  especially  when  dry,  owing  partly  no  doubt, 
to  the  fragile  nature  of  the  scalariform  tissue,  and  probably  still  more  to  the  very  small  quantity  of  parenchyma  and 
the  axis  being  formed  of  a  denser  substance  than  any  other  part . 

The  ramification  of  this  plant  is  highly  pecidiar,  and  uniformly  takes  place  in  the  following  manner.  Each  ulti- 
mate branch,  when  fully  formed,  Plate  CVII.  bis,/.  1,  (and  the  plant  itself,  when  consisting  of  a  single  uubranched 
stem)  elongates  no  further  in  any  succeeding  year,  but  gives  origin,  towards  its  extremity,  to  five  or  six  lateral  amenta  ; 
these  arise  from  the  centre  of  a  depression,  bounded  by  a  low  cup-shaped  sheath  (Plate  CIV./.  1).  All  but  a  few  of 
the  upper  of  these  amenta  are  floriferous  ;  they  fall  away  after  they  have  performed  their  functions,  leaving  a  cicatrix 
on  the  ramulus,  very  visible  even  on  the  oldest  stems,  below  every  articulation.  The  upper  empty  amenta,  however, 
(Plate  CVII.  bis,  f.  1,  a),  elongate  during  the  autumn,  one  or  both  of  them,  causing  the  ramification  to  be 
frequently  either  alternate  or  dichotomous ;  the  bracteee  are  separated  during  this  elongation,  become  recurved,* 
fall  off  and  leave  a  naked  newly-formed  branch  (Plate  CVII.  bis,f.b.),  fully  developed  by  the  month  of  Sep- 
tember ;  toward  the  upper  part  of  this,  other  amenta  are  formed  and  the  process  is  repeated.  The  apex  of 
the  originally  idtimate  branch,  now  a  stem,  is  reduced  to  a  mere  point  (c),  always  discernible  close  to  the  articulation 
even  of  the  oldest  stems,  though  often  very  inconspicuous.  Occasionally,  three  amenta  are  developed  into  branches,  but 
this  effecting  a  trichotomous  ramification,  is  rare.     The  articulation  of  the  stem  in  Myzodendron  is  therefore  of  a

very  different  nature  from  what  occurs  in  plants,  whose  joints  indicate  an  interruption  of  continuity  in  a  rectilinear 
organ,  as  the  stems  of  Equisetum,  Casuarina,  or  Salicornia,  or  from  those  which  increase  by  new  matter  being 
developed  at  certain  intervals  from  the  apex  of  the  axis  of  growth,  as  the  trunk  of  a  Palm.  In  Viscum  album,  the 
ramification  is  truly  dichotomous,  each  internode  giving  off  two  opposite  ramuli  from  its  apex,  between  which  is  a 
third  undeveloped  bud ;  and  in  V.  salicornioides  and  Arceutholobium  ojcycedri  the  branching  is  trichotomous,  from 
both  the  lateral  and  terminal  branches  being  developed.  Another  modification  is  observable  in  a  singular  new  genus 
of  Lorantliacece,  Eubrachiou*  mihi,  {Viscum  ambiguum,  H.  et  A.).  The  idtimate  ramuli  of  this  plant  are  jointed  on 
the  stem  and  appear  not  to  ramify  further,  but  to  bear  amenta  similar  to  the  bracteate  spikes  of  M.  punctulatum, 
all  of  which  are  fertile  and  caducous,  the  rainulus  elongating  and  producing  year  by  year  new  amenta,  as  the  old 
ones  drop  away. 

The  axis  of  the  stem  and  branches  of  M.  punctulatum  is  remarkably  eccentric,  the  greater  quantity  of  scalariform 
tissue  being  deposited  on  the  under  side  of  these  organs,  a  circumstance  arising  from  the  horizontal  direction  the 
whole  plant  assumes.  An  analogous  eccentricity  in  the  position  of  the  medulla  in  the  horizontal  branches  of 
coniferous  trees  is  very  evident,  though  not  so  conspicuous,  iu  other  woody  plants  whose  stems  are  as  slender 
as  those  of  Myzodendron.  The  truly  amentaceous  inflorescence  of  this  plant  is  common  also  to  Antidaphne, 
Eubrachion,  Lepeostegeres,  Blume,  Tupeia  and  others  of  its  congeners,  if  examined  at  an  early  stage.  The  male 
flowers  are  abundant,  and  the  females  much  rarer  in  Hermite  Island,  this  preponderance  of  males  was  also  very 
marked  in  the  M.  bracliystacJiyum. 

Mr.  Brown  f  first  observed  the  singular  position  of  the  stomata  in  this  species,  which  are  placed  one  on  the 
apex  of  each  tubercle  of  the  stem,  and  communicate  with  the  cavity  or  chamber  beneath,  the  respiratory  cavity 
of  some  authors.  The  cells  of  which  the  cuticle  is  composed  are  so  completely  incorporated  into  a  uniform 
integument,  that  the  curved  utricles,  which  bound  the  mouth  of  the  stoma  in  most  plants,  are  here  hardly  apparent, 
though  it  is  to  their  presence  that  the  ridge  (Plate  CVII.  bis,/.  6,  a)  is  due.  The  aperture  itself,  as  seen  in 
/.  5  and  6  of  the  same  Plate,  is  constricted  in  the  middle,  somewhat  in  the  form  of  an  hour-glass,  but  an  opening 
is  generally,  perhaps  always,  left  between  the  adjacent  edges  of  this  constriction  or  diaphragm.  The  stoma  thus 
expands  both  outwardly  and  inwardly  into  a  sort  of  cup,  the  outer  of  which  is  frequently  filled  with  an  opaque  mass, 
and  the  chambers  beneath  traversed  by  filaments  of  a  viscid  substance  stretching  from  one  wall  to  the  other  (/.  5). 
In  the  external  cavity,  when  empty,  parallel  concentric  hues  may  be  observed,  indicating  the  compound  nature  of 
the  walls  of  the  aperture.  These  stomata  are  abundant  on  all  surfaces  of  the  young  stems  and  branches,  but  only 
on  the  lower  surface  of  the  older  and  horizontal  stems. 

Male  flowers.  These  are  of  the  most  simple  structure,  consisting  of  a  solitary  curved  subclavate  peduncle 
in  the  axil  of  each  bractea,  bearing  at  its  apex  a  large  broad  depressed  gland,  on  each  side  of  which  an  anther  is 
seated,  (Plate  CIV./.  3,  and  4).  There  are  no  traces  of  a  floral  envelope.  The  anther  is  ovoid,  one-celled, 
opening  by  a  small  transverse  slit  at  the  apex,  and  containing  a  membranous  columella,  which  is  the  remaining 
unelaborated  tissue  from  which  the  pollen  is  formed,  the  indication  of  the  anther  being  originally  bilocular,  as  may

be  seen  on  examining  a  very  young  anther.  The  tissue  is  peculiar  and  wholly  cellular,  except  just  at  the  base  of  the 
columella,  whence  some  spiral  vessels  descend  through  the  peduncle.  A  longitudinal  section  shews  the  walls  of  the 
anther  to  be  remarkably  stout  and  formed  of  two  layers  of  cells  (Plate  CIV./  5  and  6)  ;  the  outer  of  these  are 
thick-sided,  rounded  or  hexagonal  utricles,  often  filled  with  a  yellow  chrornule  (Plate  CIV./.  6  and  7)  ;  the  inner 
on  the  contrary,  are  very  slender,  prismatic,  thin-sided  cells,  densely  packed  together  and  radiating  from  the  inner 
wall  of  the  anther  which  they  line  with  their  bases,  and  which  has  no  further  membrane  intervening  between  these 
prismatic  cells  and  the  pollen.     The  latter  is  yellow,  globose,  and  echinulate,  like  that  of  other  Loranthacea. 

The  gland,  on  each  side  of  which  the  anthers  are  seated,  indicates  the  position  of  the  undeveloped  ovarium  in 
the  male  flowers  ;  it  is  very  conspicuous  in  all  the  species,  and  in  Antidaphne,  Pcepp.,  which,  in  this  respect,  does  not 
differ  from  Myzodendron,  although  its  author*  has  described  the  filaments  as  calycine  pieces,  antheriferous  at  the  apex 
and  the  three-lobed  gland  as  a  corolla.  In  Tupeia  Antarctica,  again,  where  the  segments  of  the  perianth  are 
evidently  articulated  on  the  top  of  the  pedicel,  the  male  flowers  bear  an  almost  imperceptible  prominence  in  their 
centre.     In  Eubrachion  the  rudimentary  ovarium,  in  the  centre  of  the  male  flower,  is  much  more  fully  formed. 

In  some  respects  the  male  flower  of  this  genus  resembles  that  of  a  species  of  Gnetum,  where  a  solitary 
filament,  similar  to  the  peduncle  of  Myzodendron,  arises  from  a  sheathing  bract  and  bears  at  its  apex  two  collateral 
adnate  cells,  opening  by  apical  slits  which  are  at  right  angles  to  the  broad  axis  of  the  stamens,  (as  in  Lemna),  and 
contain  a  central  free  columella ;  and  where  a  vascular  bundle  descends  from  the  base  of  each  anther  down  the 
filament.  The  terminal  dehiscence  is  comparatively  rare  in  one-celled  anthers,  though  seen  in  Krameria,  where  the 
cells  coalesce  into  one.  The  single-celled  anther  of  M.  punctutatum  may  be  further  compared  with  two  of  those 
composing  the  rnultilocular  anther  of  Vucum  alburn  +,  in  each  of  which  loculi  there  is  one  point  from  which  the  pollen- 
grains  are  developed  ;  or  to  one  half  of  the  anther  of  most  phaenogamic  plants,  where  the  developement  of  the 
pollen  takes  place  at  two  points!  and  in  which  a  ridge  is  afterwards  left  in  the  cell,  analogous  to  the  columella  in 
this  genus.  I  much  regret  not  having  the  opportunity  of  comparing  this  with  the  Castraa  falcata,  St.  Hil.,  a 
Braziban  plant,  allied  to  Viscuni,  but  having  its  pollen  developed  in  the  apex  of  the  segments  of  the  perianth.  § 
The  spuriously  one-celled  anther  of  Tupeia?  incana  (Fisciim,  Hook.  Ic.  Plant,  t.  73.)  is  of  an  entirely  different  nature. 
There  the  two  original  cells,  which  are,  as  in  ordinary  stamens  collateral,  open  by  lateral  slits,  wliich  become 
confluent  above.     This  is  exactly  what  happens  in  Callitriche  and  many  other  plants. 

I  know  of  no  plant  exhibiting  a  structure  in  the  inner  cells  of  the  walls  of  its  anther  similar  to  Myzodendron, 
except  perhaps,  the  Saprium  G-riffitlmi,  Br.,  a  transverse  section  of  whose  anther,  given  by  Mr.  Griffiths,  ||  appears 
to  present  radiating  prismatic  cells.  The  outer  layer,  again,  is  a  portion  of  the  same  cuticle  surrounding  other 
more  cellular  parts  of  the  plant. 

Female  flowers.  I  have  only  seen  the  ovarium  in  Valdivian  specimens,  apparently  of  this  species,  gathered  by 
Mr.  Bridges  ;  figured  at  Plate  CIV./.  9  and  10.  They  are  sessile,  in  pairs,  in  the  axil  of  each  bractea.  The  calyx  is 
adherent  with  the  ovarium  and  terminates  in  a  thickened  ring  forming  an  entire,  very  short  lirnb  immediately  below 
the  insertion  of  the  style.  It  is  trigonous,  and  at  each  angle  is  a  slit,  leading  to  a  longitudinal  canal  that  encloses  a 
stout  filament,  or  seta.  This  seta  ascends  from  the  base  of  the  ovarium  and  gradually  elongating,  finally  escapes 
from  the  cavity  where  it  was  lodged  (Plate  CIV./  10)  ;  it  is  composed  of  elongated  cells  cohering  by  their 
viscidity.     The  ovarium  is  one-celled  ;  the  cavity  minute  and  wholly  filled  by  an  erect   short   column,   that   bears

three  obliquely  pendulous  naked  ovules  at  its  apes,  these  are  lodged  each  in  a  pouch  in  the  wall  of  the  ovarium  at 
first,  but  the  cell  gradually  ddates,  and  leaves  the  column  and  ovules  free,  as  represented  at  fig.  11  of  Plate  CIV. 
The  ovules  are  cellular  and  entirely  naked,  without  any  markings  on  the  surface.*  In  the  depression  at  the  apex  of 
the  ovarium,  bounded  by  the  almost  obsolete  limb  of  the  calyx,  is  a  very  obscure  depressed  disc,  from  which  projects  a 
short  stout  style,  terminating  in  three  erect  oblong  stigmata,  papillose  externally.  A  transverse  section  of  the  young 
ovarium  shews  no  distinction  between  the  adherent  calyx  and  ovarium ;  further  than  that,  as  it  will  afterwards  appear, 
the  fissures  penetrate  the  calyx  only,  the  seta  they  contain  lying  against  the  walls  of  the  ovarium  itself. 

In  its  trigonous  form,  the  ovarium  of  Myzodendron  resembles  that  of  one  species  of  a  new  South  American 
genus  of  LorantJtacea,  allied  to  Tupeia,  which  I  have  seen  in  fruit  only  and  shall  call  Lepidoceras,  from  the  curious, 
deciduous  membranous  scale  that  terminates  the  leaf.  The  genus  Tupeia  itself  has  also  a  similar  trigonous 
ovarium,  but  does  not  possess  the  ovuliferous  free  column,  which  is  very  evident  in  this  genus.  T.  Antarctica 
has  also  a  highly  conspicuous  superior  four-partite  perianth  to  the  female  flower,  which  being  deciduous  and  only 
visible  at  a  very  early  period,  before  the  inflorescence  quits  its  protecting  scales,  has  escaped  the  notice  of  recent 
authors.  M.  Korthals  J  refers  the  Viscam,  umbellatum  and  Reinwardtianum  of  Blume,  two  Javanese  plants,  to 
Tupeia,  from  which  Miquel  §  suggests  their  separation.  That  they  do  constitute  a  distinct  genus  is  extremely 
probable,  because  of  the  presence  of  bracts  at  the  base  of  the  female  flower,  and  (if  we  may  judge  from  the  some- 
what incomprehensible  figure  given  by  M.  Korthals)  by  some  other  characters  of  the  flower  and  fruit.  Until, 
however,  the  true  nature  of  the  placentation  of  the  original  species  of  Tupeia  ||  is  known,  and  this  is  not  described 
by  the  authors  %  of  the  genus  or  any  subsequent  writer,  its  affinities  cannot  be  fully  determined.  Korthals 
was  the  first  to  describe  any  plant  of  the  Order  Lorantliaeece  to  have  a  free  central  column  in  the  ovarium,  and 
pendulous  ovules  ;  but  laying  too  much  stress  upon  this  character  he  removed  the  plants  in  which  he  observed  it, 
together  with  the  genus  to  which  he  referred  them  (with  whose  typical  species  he  was  unacquainted),  to  Santalacea. 
Mr.  Brown,**  who  has  long  been  conversant  with  the  structure  of  Myzodendron,  points  out  its  relation  to  Santalacea. 
This  affinity  between  Santalacea  and  Lorantliaeece  is  perhaps  most  obvious  in  Myzodendron,  from  the  comparative 
facility  with  which  its  ovarium  may  be  dissected,  and  the  column  and  ovules  removed,  and  it  equally  shews  the  relation 

*  The  position  of  the  future  embryo  proves  that  these  ovules  must  be  anatropous,  though  I  cannot  perceive 
any  sign  of  raphe,  chalaza  or  foramen.  The  pollen-tube  probably  reaches  the  foramen  through  the  walls  of  the 
pouch  in  which  the  ovulurn  is  lodged  at  an  early  period. 

t  Of  this  I  have  seen  two  species,  both  imperfect.  The  genus  may  be  recognised  by  its  small  leaves,  each 
terminated  by  a  broad  deciduous  scaly  apex,  and  its  solitary  axillary  female  flowers  whose  perianth  is  deciduous.

of  Tupeia.  Though  differing  in  the  bracteate  female  flowers  and  unilocular  anthers,  its  perianth,  and,  I  believe, 
the  structure  of  the  ovarium,  are  the  same  in  both.

all  bear  to  Olacinea,  as  was  also  first  indicated  by  Mr.  Brown*  and  afterwards  well  illustrated  by  M.  Decaisne, 
after  a  comparison  of  the  ovules  of  Ykcum  album, f  with  those  of  Thedum.  The  ripe  fruit  of  M. punctulatum  forms 
an  achenium,  which  generally  dehisces  longitudinally  and  allows  of  the  partial  or  complete  exsertion  of  the 
seed ;  but  I  am  not  aware  whether  germination  takes  place  by  the  embryo  becoming  thus  excluded,  or  whether, 
as  in  the  following  species,  the  radicle  protrudes  at  the  apex  of  the  fruit,  pushing  the  disc  and  style  before  it. 
The  feathery  filaments  (hereafter  to  be  described)  are  not  so  long  in  this  species  as  in  the  following,  or  probably 
as  in  any  of  its  congeners,  except  the  M.  imbricatum,X  Pcepp.,  of  South  Chili ;  they  are  plumose  with  long  hairs, 
which  are  capitate  at  the  apex.  The  walls  of  the  pericarp  are  more  membranous  here  than  in  the  other  species, 
and,  when  fully  ripe,  the  ealycine  portion  looks  like  three  plates,  attached  longitudinally  by  part  of  their  surface 
to  the  endocarp  ;  the  filaments  being  lodged  in  the  spaces  formed  by  their  contiguous  non-adherent  portion  (Plate 
CIV./.  16.).  The  stout  central  column  of  the  ovarium  is  elongated  in  the  fruit  into  a  slender  chord,  pressed 
between  the  seed  and  walls  of  the  cavity  of  the  fruit,  and  resembles  a  funiculus  ;  its  edges  are  ragged  from  the 
rapid  elongation  of  its  substance.  The  true  funiculus  is  extremely  short,  and  bears  at  its  base  the  two  very 
minute  unimpregnated  ovules  (Plate  CIV./.  18  and  19).  The  seed  is  linear-oblong,  narrow  and  obtuse  at  both 
extremities.  The  albumen  is  copious,  formed  of  utricles  that  at  first  are  readily  separable ;  and  though  the 
outer  ones  adhere  closely,  they  do  not  seem  covered  with  any  distinct  testa ;  a  cavity  in  the  upper  part  contains 
the  greater  portion  of  the  embryo,  which  is  of  very  highly  organized  tissue,  and  the  radicle  which  is  not  immersed  in 
the  albumen  is  covered  with  a  membrane  apparently  continuous  from  the  funiculus,  which  at  an  early  period  may  be 
traced  downwards,  lining  the  cavity  of  the  albumen  (Plate  CIV.  /.  19,  where  the  membrane  is  represented 
as  too  thick  in  texture).  At  no  time  can  I  detect  the  lower  portion  of  this  membrane  (first  observed  by 
Mr.  Brown),  except  whilst  the  cells  of  the  albumen  are  loosely  held  together  and  may  be  scraped  by  the  knife 
from  its  surface,  and  then  it  appears  homogenous  and  of  a  different  texture  from  what  covers  the  radicle, 
which  is  cellular  (Plate  CIV.  /  20).  The  embryo  is  very  small,  the  radicular  extremity  capitate,  with  a 
depression  at  the  top  ;  the  cotyledonary  terete,  abrupt,  slightly  curved  and  fistulose  at  the  apex  :  the  cotyledons  are 
consolidated  and  present  no  trace  of  any  line  of  union.  The  tissue  of  the  radicle  differs  materially  from  that  of 
the  cotyledons,  which  may  be  seen  even  before,  but  still  more  remarkably  after,  dissection  (Plate  CIV.  /  20).  The 
upper  portion  of  the  capitulum,  above  the  upper  margin  of  the  cavity  of  the  albumen,  is  composed  of  delicate  filiform 
cells  of  considerable  length,  enclosed  in  a  cellular  cuticle  of  great  tenuity.  The  lower  half  and  terete  cotyledonary 
portion  consists  of  closely-packed  oblong  cells,  projecting  in  the  form  of  a  cone  towards  the  radicular  end.  This 
structure,  somewhat  modified,  exists  in  M.  bracJiystachi/um  (Plate  CV.  /.  20  and  21),  the  tissue  of  the  radicle 
being  much  more  lax  than  that  of  the  cotyledons.  The  peculiar  functions  of  the  radicle  doubtless  demand  this 
highly  organized  structure,  both  for  rapid  elongation  and  for  the  sudden  spread  of  the  membrane  by  which  the 
following,  and  probably  all  the  species,  are  first  attached  to  the  bark  whereon  they  grow.  In  the  present,  the  true 
radicle  which  pierces  the  bark  is  probably  the  conical  continuation  of  the  cotyledonary  portion. 

The  plumose  pappi  of  the  achenium  afford  one  of  the  great  peculiarities  of  this  genus  ;  of  their  function  there 
can  be  no  doubt,  though  their  origin  and  true  nature  are  not  quite  so  evident.  De  Candolle,§  from  an  examination 
of  very  imperfect  specimens,  described  them  sufficiently  accurately,  as  scales  contained  in  the  walls  of  the  pericarp. 
Guillemin  ||  also  considers  them  to  be  pappiform  appendices,  contained  in  fissures  of  the  achenia.     Neither  of  these

authors  ofl'ers  any  explanation  of  their  true  nature.  Poeppig  *  describes  several  species,  and,  trusting  more  to 
a  theoretical  opinion  of  their  origin,  than  to  a  careful  analysis  of  the  parts,  or  the  definitions  of  De  Candolle 
and  Guilleinin,  he  misapprehends  the  structure  of  the  ovarium,  considering  it  to  be  a  compound  body,  made  up  of 
three  carpels  combined,  and  of  the  plumose  filaments,  which  are  described  in  the  generic  character  as  Setae  hypo- 
gynae  alternating  with  the  ovaria,  and  in  the  observations  on  the  genus  are  doubtfully  called  Staminodia.  Lastly, 
Endlieher  f  regards  the  single  ovarium  as  compounded  of  six,  enclosed  in  a  three-parted  involucre,  three  of 
them  fertile  and  three  sterile,  the  latter  being  the  plumose  filaments. 

The  female  flower  of  Myzodendron  consisting  of  a  solitary  ovarium,  enclosed  in  the  adherent  tube  of  the 
calyx,  it  is  evident  that  the  plumose  setae  must  be  a  production  of  the  calyx  or  ovarium.  Their  function  and 
appearance  resemble  the  pappus  of  Composite,  and  particularly  of  Valeriana  in  being  only  fully  developed  during 
the  ripenmg  of  the  seed.  They  cannot  be  compared  with  the  four  stout  woody  nerves  of  Tupeia  Antarctica,  which 
ascending  from  the  pedicel,  terminate  in  the  sarcocarp  of  its  berry  in  four  sharp  points  that  arch  over  an  opening 
in  the  upper  end  of  the  endocarp  of  that  plant,  for  the  setas  of  Myzodendron  contain  no  spiral  vessels,  and 
the  true  nerves  of  the  calyx,  though  very  obscure,  may  be  traced  in  some  of  the  species,  as  in  M.  brackystacliyum, 
where  they  appear  alternating  with  the  position  of  the  setae  (Plate  CV.  /.  11). 

The  tissue  of  which  these  setae  are  composed,  is  identical  with  what  forms  the  sarcocarp  of  Tupeia  and  Viscum, 
namely,  elongated  viscid  cells  of  great  tenuity  filled  with  a  glutinous  matter ;  in  most  Lorantliacear  this  tissue 
surrounds  the  endocarp  and  at  an  early  period  deliquesces  into  a  homogenous  viscid  fluid,  like  that  of  Viscum.  When 
looking  over  the  plants  of  this  order,  in  Dr.  Lindley's  herbarium,  I  remarked  one    whose  ripe  pericarp  had  burst 
during  pressure  and  emitted  a  cottony  substance  ;  that  gentleman  liberally  gave  me  specimens  for  examination, 
which  showed  the  sarcocarp  to  be  intermediate  in  its  nature  between  that  of  Tupeia  and  of  Myzodendron,  being 
feathery  and  neither  so  deliquescent  as  in  the  former,  nor  elaborated  into  such  a  peculiar  organ  as  in  the  latter. 

The  elaboration  of  these  setae,  from  cellular  tissue,  cannot  be  regarded  otherwise  than  a  very  singular 
phenomenon,  and,  so  far  as  my  observations  serve,  it  appears  that  it  is  merely  the  result  of  a  rapid  elongation  of 
cellular  tissue.  The  viscid  substance,  then,  in  this  genus,  instead  of  surrounding  the  endocarp,  is  confined  within 
three  fissures,  and  there  collected  into  a  terete  or  compressed  body,  which,  escaping  froni  its  confinement,  rapidly 
elongates  from  the  growth  of  the  cells  which  compose  it,  more  than  from  the  addition  of  new  matter.  The  plumose 
appearance  is  caused  by  the  separation  of  some  of  the  utricles,  which  diverge  on  all  sides  in  the  species  in  winch 
the  setae  are  terete,  or  in  their  opposite  margins  when  the  latter  are  compressed.  Of  all  the  species,  the  setae  of 
M.  oblongifolium  are  the  longest,  and  there  are  various  gradations  in  length  and  tenuity  between  them  and  those  of 
M.puuctidatuni.  The  M.  Unearifolium,§  DC,  has  not  only  very  long  and  slender  filaments,  but  its  whole  endo- 
carp is  at  times  surrounded  with  a  feathery  substance,  which  is  thus  not,  as  in  its  congeners,  confined  in  loculi : 
when  placed  in  water  this  feathery  substance  deliquesces.  In  M.  imbricatum,  Pcepp.,  the  fissures  of  the  pericarp 
are,  according  to  the  author  of  that  species,  filled  with  undivided  stout  obtuse  filaments,  collected  together  at  the 
base,  and  never  exserted. 

I  need  scarcely  allude  to  the  fact,  that  the  function  performed  by  the  gluten  of  Viscum  and  the  feathery  setae 
of  Myzodendron  is  identical,  though  effected  in  a  different  way,  and  that  it  affords  a  singular  instance  of  nature's 
employing  the  same  means  in  a  very  dissimilar  manner  to  the  attainment  of  the  same  end.     The  viscid  matter  of

the  Misseltoe  has  been  supposed  to  nourish  the  embryo  during  the  first  stage  of  germination ;  which  may  be  the  case  ; 
though  from  Myzodendron  requiring  no  such  adventitious  assistance,  it  is  more  probable  that  it  serves  in  both,  merely 
as  a  means  of  attaching  the  seed  to  the  plant  it  attacks.  In  most,  or  perhaps  all  Lorauthacea>,  germination  is 
continued  up  to  a  considerable  period,  before  the  albumen  and  pericarp  are  detached  from  the  embryo.  I  have  not 
seen  its  exsertion  in  this  species,  which  takes  place,  probably,  as  in  M.  Irachystachyum,  through  the  apex  of  the 
pericarp,  and  not  through  a  lateral  fissure.  In  many  plants  of  the  order,  there  is  a  special  provision  for  this ;  for 
instance,  in  Tupeia,  where  the  upper  extremity  of  the  endocarp  is  open,  and  where  the  nerves  of  the  pericarp  do  not 
anastomose  above ;  and  in  Eubrachion,  where  there  is  a  similar  foramen,  opening  into  a  cavity  full  of  a  viscid  fluid, 
whence  it  seems  likely  that  the  radicular  extremity  in  these  two  genera  may  carry  out  along  with  it  some  of  this 
viscid  matter,  the  better  to  secure  its  adhesion  to  a  particular  spot.  Lastly,  I  shall  allude  to  the  cellular  tissue  of 
the  radicular  extremity  of  M.  Irachystachyum  being  formed  of  viscid  elongated  utricles,  which  I  cannot  distinguish 
from  those  composing  the  gluten  of  the  sarcocarp  of  other  Loranthacece,  and  would  hence  suggest  that  we  have  in  one 
species  of  this  genus,  where  no  medium  exists  in  the  sarcocarp  for  attaching  the  radicle  to  the  bark,  a  perfectly 
similar  substance  supplied  by  the  radicle  itself. 

Mr.  Brown,  in  his  paper  on  Rafitesia  in  the  19th  volume  of  the  Linnean  Transactions  so  often  alluded  to, 
substitutes  the  original  name  of  Myzodendron,  given  by  Banks  and  Solander,  for  that  of  Misodendrum,  which 
was  probably  inadvertently  adopted  by  De  Candolle.  The  latter  author  has  also  mistaken  Staten  Land  in  Fuegia,  for 
Staten  Island  in  the  United  States,  and  hence  considered  this  to  be  a  native  of  North  as  well  as  South  America. 

The  yellow  hue  of  Myzodendron  punctulatum  renders  it  a  conspicuous  object,  even  from  a  considerable  distance. 
It  may  be  recognized,  when  coasting  along  the  shores  of  Fuegia,  from  its  contrasting  so  strongly  with  the  other- 
wise lurid  colour  of  the  dusky  forests.     It  grows  indifferently  upon  the  evergreen  or  deciduous-leaved  Beech.

The  important  and  conspicuous  characters  that  separate  this  and  the  following  from  the  M.  punctulatum,  and 
which  have  induced  me  to  subdivide  the  genus,  are,  the  absence  of  tubercles  on  the  stem  and  branches,  the  ramuli 
being  foliaceous  and  not  bracteate  or  scaly,  the  triandrous  male  flowers,  the  larger  column  in  the  ovarium,  the 
deeply  sulcate  albumen,  and  especially  the  structure  of  the  stem,  which  differs  so  remarkably  in  the  two  subgenera, 
that  no  one,  from  an  examination  of  their  wood  alone,  would  hesitate  in  pronouncing  them  to  be  plants  widely 
separated  in  a  Natural  System.

Anatomy  of  the  stem.  A  branch  of  this  species,  after  attaining  the  age  of  two  years  and  upwards,  consists 
principally  of  a  soft  white  cellular  tissue,  occupying  the  axis  of  the  plant  and  communicating  with  the  thick  bark  by 
means  of  broad  medullary  rays.  The  latter  are  separated  by  woody  plates,  disposed  in  two  concentric  series,  and 
formed  almost  entirely  of  scalariform  tissue  with  sometimes  pleurenchyma.  Cuticle.  This  is  very  stout  in  texture  : 
in  a  first  developed  branch  it  consists  of  only  one  row  of  small  cells  (Plate  CYII.  bis,  f.  11)  these  must  be  rapidly 
added  to,  for  after  another  year  the  cuticle  of  the  same  branch  is  of  much  greater  density  and  formed  of  many  series 
of  cells,  much  blended  together,  though  not  so  completely  as  to  assume  the  appearance  of  a  homogeneous  tissue 
without  any  trace  of  cellularity,  which  it  afterwards  attains  (Plate  CYII. Jiff.  4,  5,  and  6).  The  cuticle  is  devoid 
of  stomata  commonly  so  called,  but  furnished  with  numerous  longitudinal  prominences,  each  marked  by  a  fissure. 
A  transverse  section  of  one  of  these  is  given  at  Plate  CV1I.  /.  4,  where  the  appearance  is  as  of  several  layers  of 
cuticle  superimposed  and  forming  the  prominence,  becoming  cellular  towards  the  centre,  and  depressed,  pushing 
the  subjacent  epiphlceurn  before  it.  There  is  no  actual  stoma  or  communication  between  the  external  atmos- 
phere and  tissue  of  the  bark,  further  than  what  may  be  supposed  to  be  afforded  by  cellular  tissue,  which  is  a 
rapid  conductor  of  moisture.  These  are  very  evident  in  the  branches  of  the  second  year,  no  doubt  answer  to 
stomata,  whether  performing  the  same  functions  or  no,  and  are  an  instance  either  of  the  cuticle  retaining  its 
originally  cellular  organization  at  the  point  where  they  occur,  or  reverting  to  that  structure. 

Bark.  This  is  composed  almost  entirely  of  a  mass  of  cellular  tissue,  shrinking  much  when  the  stem  is  dry. 
The  epiphlocum  is  formed  of  several  rows  of  transversely  elongated  thick-walled  cells,  it  occasionally  contains  air- 
cavities,  but  these  are  not  so  numerous  or  conspicuous  as  in  M.  punctulalnm.  The  vessels  of  the  liber  are  disposed 
about  half  way  between  the  cuticle  and  wood,  are  often  very  inconspicuous  and  formed  of  scattered  bundles  of  fibres 
(Plate  CVII.  /.  5  and  6  a.)  protected  by  very  thick-walled  cells,  as  in  most,  if  not  all,  the  Loranthacea,  at  other 
times  they  are  in  two  series  or  variously  disposed.  This  tissue  does  not  appear  to  pass  from  one  internode  to 
another,  but  to  be'  interrupted  at  each  articulation,  as  M.  Decaisne  found  to  be  the  case  in  Viscum*  The  paren- 
chyma between  the  vessels  of  the  liber  and  wood  is  often  dense,  sometimes  but  rarely  these  vessels  are  seen  to 
be  immediately  in  contact  with  the  wood  as  at  Plate  CVII.  /.  5  and  6  b.  Wood.  Within  the  bark  are  arranged 
two  concentric  series  of  woody  plates  or  wedges,  these  two  series  are  separated  by  a  zone  of  cellular  substance,  and 
are  generally  arranged  with  tolerable  precision :  besides  these  the  pith  of  the  plant  is  intruded  upon  by  other 
wedges  or  bundles  of  vascular  tissue,  unsymmetrieally  disposed,  one  of  them  often  occupying  the  axis  itself.  Each 
wedge  or  plate  is  composed  principally  of  concentric  layers  of  very  large  vam  scalariformia,  becoming  more  densely 
packed  and  much  smaller  in  diameter  towards  the  axis  of  each  layer,  where  they  are  almost  invariably  furnished  with 
a  spiral  filament.  Between  the  layers  of  the  first  three  or  five  years  there  is  generally  deposited  two  bundles  of 
pleurenchyma  similar  to  that  of  the  liber,  one  on  each  side  (Plate  CVII.  ter,  f.  .f)  but  between  the  more  recent 
layers  there  intervenes  only  the  more  delicate  vascular  tissue  (/.  1  arid  2.  e)  :  as  mentioned  above,  however,  pleu- 
renchyma is  sometimes  more  copiously  deposited  between  every  layer,  as  at  Plate  CVII.  /.  5  and  6,  b.  The 
narrow  portion  of  each  wedge  invariably  rests  on  a  mass  of  pleurenchyma  (Plate  CVII.  ter,  f.  1.  y,)  deposited  at 
the  same  time  as  the  fibres  of  the  liber  c,  that  is  during  the  first  year,  as  in  the  common  Misseltoe.  The  wedges  of 
wood  belonging  to  the  second  series  are  smaller  than  those  of  the  first,  but  similarly  formed  in  all  respects,  and 
consisting  of  as  many  layers,  though  the  inner  are  very  inconspicuous. 

The  pith  consists  of  cellular  tissue  similar  to  that  of  the  liber,  and  is  very  lax  even  in  the  older  stems. 

The  transverse  section  of  this  stem,  appears  at  first  sight  to  differ  very  remarkably  from  that  of  most  exo- 
genous plants ;  this  arises  from  the  wood  being  deposited  in  two  concentric  series,  separated  by  a  broad  zone  of 
parenchyma,  from  the  great  breadth  of  the  medullary  rays,  the  irregular  distribution  of  the  fibres  of  the  liber

which  are  sometimes  biserial,  and  the  disproportionate  amount  of  scalariform  tissue.  The  structure  of  M.  punctu- 
latum  is  however  far  more  abnormal,  fibres  of  pleurenchyma  being  deposited  in  the  axis  of  the  stem,  thus  replacing 
the  pith,  and  forming  very  obsolete  rays,  and  all  future  increment  of  the  stem  being  effected  by  an  addition  of 
layers  of  variously  marked  scalariform  tissue  alone,  as  far  as  I  have  been  able  to  observe. 

Formation  of  wood.  I  shall  next  describe  the  course  the  vascular  tissue  pursues  in  the  newly  formed  buds 
and  branches,  and  thus  attempt  to  explain  the  origin  of  the  two  series  of  woody  plates  which  this  species  and 
M.  quadrifiorum  DC.  possess. 

A  transverse  section  of  the  stem  of  a  flower-  or  leaf-bud  made  in  the  first  year  of  its  formation,  (Plate  CVII. 
bk,  f.  10  and  11),  presents  a  mass  of  globular  utricles,  covered  with  a  delicate  cuticle  (a)  formed  of  one  moniliform 
row  of  cells,  and  traversed  by  one  series  of  twenty  or  thirty  vascular  bundles  (b).  These  bundles  descend  from 
the  base  of  each  leaf,  traverse  the  branch  and  enter  the  stem.  A  transverse  section  of  the  stem  again  from  which 
the  bud  or  branch  is  given  off,  and  below  the  point  of  attachment  of  the  latter,  presents  two  concentric  series  of 
vascular  bundles  (CVII.  bk,  f.  12.  b,  c),  besides  an  imperfect  third  consisting  of  a  few  scattered  promiscuously  in 
the  axis  of  the  stem  ;  the  outer  series  was  formed  in  the  former,  the  inner  is  derived  from  the  buds  and  branches 
of  the  present  year. 

A  longitudinal  section  through  the  axis  of  the  stem,  so  made  as  to  pass  also  through  the  axis  of  the  branch, 
clearly  shews  that  it  is  due  to  the  position  in  which  the  buds  are  developed  that  a  second  series  of  wedges  of 
wood  is  deposited.  The  buds  originate  towards  the  axis  of  the  stem,  within  the  vascular  bundles  of  the  previous 
year,  (Plate  CVII.  bk,  f.  10.  b),  and  opposite  the  insertion  of  the  petiole  (/).  The  whole  of  the  vascular  tissue 
descending  from  a  bud  is  consequently  deposited  within  the  wood  of  the  former  year  (/.  9  e.)  generally  each  bundle 
on  entering  the  stem  from  the  branch  divides,  one  portion  joining  the  old  wood,  the  other,  remaining  free  and 
descending  the  stem,  forms  the  second  or  inner  plate  of  wood.  The  course  of  the  bundles  is  however  very  uncertain, 
sometimes  they  do  not  divide,  but  either  join  the  old  vascular  tissue,  or  continue  free,  and  at  others  one  portion 
crosses  to  the  opposite  side  of  the  stem.  Figures  9  and  10  of  Plate  CVII.  bk,  shew  various  modifications  of  the 
course  these  vessels  pursue,  the  uniform  result  being,  that  in  the  internode  of  the  second  year  all  the  wedges  of 
wood  are  formed,  though  these  become  lower  in  the  stem  multiplied  by  division. 

As  each  bud  gives  off  thirty  to  forty  bundles  of  vessels,  and  these  being  superadded  to  those  of  the  branch, 
such  a  plexus  arises  at  the  contracted  junction  of  the  second  year's  branch  and  that  of  the  third  year  that  their  course 
can  no  longer  be  followed.  Each  of  the  woody  plates  however,  continues  to  receive  accessions  throughout  the  bfe  of 
the  plant,  those  of  the  inner  series  containing  as  many  layers  as  those  of  the  outer.  It  is  hence  evident  that  the 
bundles  first  arranged  in  the  branch  of  the  second  year  (/.  10  A),  on  entering  that  of  the  third  year  (/.  10,  B), 
must  present  a  very  complicated  arrangement  of  tissues.  The  increase  of  the  stems  in  diameter  being,  however, 
effected  throughout  the  length  of  the  plant  by  an  addition  of  matter  to  the  outside  of  both  concentric  series  Of 
wedges,  it  follows  that  the  growth  is  in  one  sense  at  the  same  time  Exogenous  and  Endogenous. 

However  complicated  the  nature  and  disposition  of  these  tissues  may  cause  the  developement  of  the  stems  to 
appear,  the  order  in  which  each  wedge  of  wood  and  its  layers  of  pleurenchyma  are  deposited  in  the  first  year  is  tin- 
same  as  in  Vkcum ;  nor  are  the  tissues  themselves  very  different  from  those  of  that  plant.  This  is  seen  by  comparing 
the  figure  of  a  first  year's  branch  of  Vkcum  as  given  in  M.  Decaisne's  elaborate  essay*  pi.  iii.  f.  4,  or  in  Link's 
superb  '  Icones'f  pars  iv.  t.  8.  f.  1,  with  that  of  .1/.  brachystachyum,  (Plate  CVII.  bk,f.  13). 

In  both  M.  brachystachyum  and  Vkcum.  album  two  bundles  of  pleurenchyma  are  first  deposited,  one  anterior  and

the  other  posterior  to  the  wood,  the  former  constituting  the  fibres  of  the  liber,  between  which  and  the  wood 
all  new  layers  of  the  latter  are  placed.  The  three  or  four  succeeding  layers  of  wood  are  accompanied  in  Myzo- 
dendron  with  bundles  of  pleurenchyma  (Plate  CVII.  ter,  f  ,f),  and  Link  figures  occasional  fibres  similar  to 
those  of  the  liber  situated  within  the  wood  of  Viscum.  In  many  other  particulars  the  structure  of  the  wood  of  this 
genus  and  Viscum  is  very  similar,  as  in  the  form  the  alburnum  assumes  (f.  1,  c) ;  in  the  narrow  tubes  containing 
a  spiral  vessel  that  occurring  at  the  inner  margin  of  the  layers,  which  they  thus  separate,  forming  in  Viscum, 
as  here,  an  obscure  medullary  sheath.  The  tissue  of  the  wood  itself,  (which  is  much  modified  in  the  different 
species  of  this  genus,  as  I  shall  hereafter  shew,)  in  the  present  species  consists  of  longer  tubes,  whose  walls, 
though  very  much  more  delicate  than  those  of  Viscum,  probably  are  similarly  perforated. 

In  some  respects  this  disposition  of  tissues  may  be  compared,  though  not  strictly,  with  that  of  Menispermacea, 
so  beautifully  illustrated  by  M.  Descaisne.*  After  the  stem  of  Cocculus  laurifolius  has  attained  a  certain  age,  a 
second  deposit  of  wedges  of  wood  is  formed  externally  to  the  liber,  but  without  any  additional  liber.  In  Myzoden- 
dron  the  two  wedges  are  deposited  within  one  year  of  each  other,  the  second  within  the  first,  and  both  are  annually 
augmented  by  new  matter  ;  in  both  wedges  however,  the  deposit  of  pleurenchyma  similar  to  that  of  the  liber,  which 
accompanies  every  layer  for  the  three  or  four  first  years,  is  withheld  from  all  future  layers. 

Wood  of  other  species.  The  above-described  structure  of  the  wood  is,  with  slight  modifications,  common  to  all 
the  species  of  the  group  Eumyzodendron.  Though  I  am  quite  unable  to  make  so  satisfactory  dissections  of  that  of 
M.  punctulatum,  from  the  very  remarkable  density  and  minuteness  of  its  tissues,  I  still  am  inclined  to  consider  that 
its  greatest  peculiarity,  the  occupation  of  the  position  of  the  medulla  by  pleurenelrynia,  is  a  modification  of  what 
occurs  in  many  Loranthacea,  and  is  owing  to  the  existence  of  a  second  or  inner  deposit  of  pleurenchyma  similar  to 
that  of  the  liber,  which  in  this  species  instead  of  being  arranged  in  separate  concentric  bundles,  is  collected  into  one  in 
the  axis  of  the  stem.  Hence  in  the  section  of  the  stem  of  a  leaf  or  flower-bud  (Plate  CVII.  ter,f.  8.),  this  tissue 
is  seen  to  be  present  instead  of  the  pith,  and  the  great  density  of  the  wood  of  the  older  stems  may,  in  a 
measure,  be  due  to  the  incompressible  nature  of  this  tissue,  and  to  the  rays  (which  cannot  be  called  medullary) 
being  also  formed,  not  of  cellular  tissue,  but  of  pleurenchyma  deposited  with  the  scalariform  in  very  small  quantities. 

Of  the  other  Eumyzodendrons  there  are  three  whose  tissues  I  have  examined,  and  added  figures  of  all,  except 
M.  ollongifolium,  which  hardly  differs  from  M.  brachystacliyum. 

In  M.  quadrifiorum,  DO,  (Plate  CVII.  ter,  f.  6  and  7,)  there  is  generally  but  one  series  of  wedges  of  wood, 
the  second  being  reduced  to  a  single  wedge,  lying  obliquely  across  the  axis  of  the  stem ;  the  vessels  of  the  liber  are 
exceedingly  inconspicuous  (/.  6,  b)  the  cellular  tissue,  bark,  and  pith  large  and  loose,  and  the  tubes  forming  the  wood 
very  large  and  few  in  number ;  the  smaller  tissue  interposed  between  the  layers  (e)  is  conspicuous.  In  the  old 
stems  I  cannot  detect  the  inner  layer  of  liber.  The  alburnum  (c)  has  the  appearance  of  compressed  cellular  tissue. 
I  have  not  met  with  woody  cells  in  this  species. 

In M.  linearifolium,  DO,  there  is  but  one  series  of  woody  plates  (Plate  CVII.  ter,  f.  3,  4  and  5).  The  cellular 
tissue  is  large  and  loose,  and  contains  both  in  the  bark  and  medullary  rays,  numerous  conspicuous  masses  of 
woody  cells  (/.  3  and  4,  a).  Both  series  of  vessels  of  pleurenchyma  (/.  b  and  y)  are  large.  Those  of  the  scala- 
riform tissue  are  of  a  greater  diameter  than  in  any  of  its  congeners,  cylindrical,  constricted,  (as  in  bothrenchyma) 
and  septate  at  intervals  equal  to  their  breadth  (/.  5.  a)  :  the  tubes  of  the  medullary  sheath  and  those  interposed 
between  the  layers  of  wood  are  of  very  unequal  diameter  and  constricted  here  and  there  (/.  5.  b). 

Wood  of  Fagus.  To  Plate  CVII.  is  added  a  sketch  of  the  wood  of  Fagus  Forsteri; — /.  11  represents  a

/.  12,  which  is  taken  from  a  branch  of  Fagus  six  years  old,  it  will  be  seen  that  the  ducts,  dotted  and  otherwise 
marked  vessels  are  large  and  abundant,  and  that  the  chief  difference  between  /.  12,  and  a  similar  section  of  one 
wedge  of  Myzodendron  brachystacliyum  f.  6,  lies  in  the  scalariform  vessels  being  disproportionately  abundant  in  the 
latter,  and  not  being  scattered  amongst  the  pleurenchyma. 

Ramification.  In  this,  as  in  M.punctulatum,  the  terminal  internodes  bear,  towards  their  upper  part  several  buds, 
each  opposite  the  axil  of  a  leaf;  of  these  the  leaf-buds  elongate  and  become  new,  permanent  internodes;  the  flower- 
buds  fall  away.  In  the  former  species  (Plate  CVII.  iis,f.  1)  the  flower-buds  were  near  the  apex  of  the  internode, 
and  two  frequently  becoming  developed  into  branches,  the  ramification  was  consequently  dichotomous.  In 
M.  bracliystachjum  (Plate  CVII.  bis,  f.  7)  the  flower-buds  are  generally  the  upper,  and  the  ramification  hence 
alternate. 

The  vaginas  enclosing  the  unprotruded  buds  are  vertically  two-lipped,  and  formed  from  the  bark  which  encloses 
a  large  cavity  communicating  almost  with  the  axis  of  the  stem  where  the  bud  is  developed.  The  dehiscence 
is  spontaneous,  before  the  included  organ  has  advanced  sufficiently  to  force  a  passage.  The  relation  of  these  parts 
to  those  of  a  germinating  embryo  is  clear  ;  the  cavity  in  the  internode  containing  the  bud  is  analogous  to  that  in 
the  cotyledonary  extremity  of  the  embryo  including  the  plumule,  whose  course  in  germination  is  thus  imitated  by 
the  buds  as  often  as  the  plant  developes  them. 

Germination.  I  have  been  able  to  watch  the  progress  of  germination  in  this  species  and  to  follow  the  course 
of  the  radicle  from  the  time  of  its  leaving  the  pericarp,  till  it  has  fully  established  itself  upon  the  tree  it  affects. 

Several  of  the  ripened  seeds,  still  enclosed  in  their  pericarps,  are  generally  detached  together  from  the  parent  plant, 
they  adhere  by  their  viscid  filaments  and  are  carried  by  the  birds,  winds,  or  other  natural  causes,  from  one  tree  to 
another,  where  they  may  often  be  seen  hanging  entangled  amongst  the  leaves  and  twigs.  The  grain  is  placed  almost 
in  contact  with  the  stem ;  it  is  immaterial  to  which  surface.  As  I  have  not  seen  young  Myzoiendrons  attached  to 
old  trunks  and  branches,  I  presume  the  young  plant  can  only  pierce  a  comparatively  newly  formed  bark.  The 
elongation  of  the  caulicule  pushes  before  it  the  disk  and  style,  which  fall  away,  and  the  radicle  always  escapes  at 
this  point  and  protrudes  beyond  the  pericarp,  to  which  the  embryo  remains  attached  until  the  parasite  has  gained  a 
firm  lodgment  on  the  tree.  The  embryo  now  generally  becomes  curved,  the  elongating  caulicule  seeking  the  nearest 
point  of  the  beech,  which  it  finally  reaches.  At  this  period  the  cotyledons,  distinctly  swollen,  are  still  contained  in  the 
shrivelled  albumen,  and  a  very  evident  notch  marks  their  point  of  union  (Plate  CVI.  /.  5).  The  radicle  now 
expands  like  the  mouth  of  a  trumpet,  is  concave  and  has  become  a  compound  body,  consisting  of  three  distinct 
parts,  1st.  a  membrane  continuous  with  the  surface  of  the  caulicule,  which  expands  horizontally  over  the  cuticle, 
is  glutinous,  and  is  the  first  inmiediate  cause  of  adhesion  between  the  bark  and  the  parasite.  2nd.  A  thick  fleshy 
sheath,  whose  convex  margins  touch  the  bark.  3rd.  A  cushion-shaped  body  in  the  axis  of  the  radicle,  which  is 
pressed  against  the  bark  and  is  destined  more  immediately  to  convey  nourishment  from  the  tree  to  the  future 
full-grown  parasite.  At  Plate  CVI.  /.  ,  is  a  germinating  seed,  with  the  cotyledonary  extremity  still  enclosed  in 
the  albumen,  and  the  radicular  expanded  as  it  appeai-s  on  reaching  the  bark  ;  /.  5  represents  the  same  attached,  with 
the  albumen  removed,  shewing  the  notch  of  the  cotyledons. 

If  a  longitudinal  section  of  the  "embyro  be  now  made,  (as  at  Plate  CVI./.  6)  there  will  be  seen,  1st,  at  the 
base  of  the  cavity  in  the  cotyledonary  extremity,  two  excessively  minute  green  bodies,  which,  at  a  later  period, 
become  developed  into  the  first  pair  of  leaves,  are  pointed  upwards  towards  the  notch  at  the  union  of  the  cotyledons, 
and  escape  by  the  rupture  of  the  membranes  that  enclose  them :  2nd.  spiral  vessels  descending  from  the  base 
of  these  which  are  lost  in  the  cellular  substance  of  the  cushion-shaped  body  (Plate  CVI.  /.  7)  :  3rd,  a  longi- 
tudinal line  indicating  a  future  separation  of  the  cotyledons  and  outer  substance  of  the  embryo,  the  latter  forming 
an  integument  that  includes  the  plumule,  cushion-shaped  body  and  its  surrounding  sheath.  This  central  mass, 
included  between  the  plumule  above  and  base  of  the  cushion  below,  is  the  growing  portion  of  the  future  plant,  all

external  to  it  being  more  or  less  accessory.  The  above  may  be  considered  the  first  stage  of  developement,  when 
the  pericarp  and  albumen  have  fallen  away  ;  the  outer  coat  of  the  radicle  is  expanded  into  a  horizontal  membrane, 
firmly  attached  to  the  cuticle  of  the  Faff  us,  and  the  cushion-shaped  body  is  pressed  against  the  stem  or  twig  of  the 
tree,  at  that  point  where  the  process  of  penetrating  the  integuments  will  begin. 

The  second  period  commences  by  the  cushion  destroying  the  cuticle  beneath  it  and  reaching  the  epiphlceum. 
Still  pushing  onwards,  it  raises  the  membranous  expansion  and  causes  the  surrounding  cuticle,  with  or  without 
some  of  the  subjacent  tissue,  to  be  also  detached  with  this  membrane,  for  a  considerable  distance  round  the  base 
of  the  radicle.  The  lesion  to  the  plant  is  now  extensive,  and  a  diseased  action,  favourable  to  the  progress  of  the 
parasite  is  induced,  for  the  whole  bark  opposite  the  Myzodendron  is  raised  from  the  wood  (Plate  CVI.  /.  8). 
The  cushion,  which  may  now  be  called  a  true  root,  is  protruded  rapidly,  and  the  disorganization  of  the  tissues 
it  meets  in  its  progress  is  equally  rapid,  a  cavity  is  formed  in  the  bark  and  the  edges  of  the  fleshy  sheath  that  surrounds 
the  root  commence  generally  to  form  a  close  adhesion  with  the  lips  of  the  wound,  (Plate  CVI./.  10  and  11). 
At  last  the  root,  having  penetrated  the  bark,  arrives  at  the  space  left  between  the  latter  and  the  wood  (Plate 
CYI.  /.  9),  and,  from  the  perpendicular  direction,  assumes  a  horizontal  one.  Previous  to  this  there  has  been  a 
deposition  of  much  disorganized  cellular  tissue  between  the  bark  and  the  wood.  The  spiral  vessels  that  descend 
from  the  plumule  have  followed  the  course  of  the  root,  which  has  gained  the  point  where  an  abundance  of 
nutritive  matter  is  retained  by  the  disorganized  cellular  tissue,  and  where  a  further  supply  is  ensured  for  the  use  of 
the  now  fully  established  Myzodendron. 

If  at  this  time,  the  end  of  the  second  period,  a  vertical  section  of  the  Myzodendron  and  Fagus  together  be 
made,  the  appearance  will  be  that  represented  at  Plate  CVI./.  10,  where  the  plunmle  is  seen  fully  developed  into 
two  opposite  leaves,  ready  for  protrusion,  and  where  also  a  large  space  is  left  that  almost  isolates  the  axis  of  the 
caulicule  from  what  remains  as  an  investing  membrane.  The  true  root,  or  cushion-shaped  body,  at  no  time 
appears  to  form  an  adhesion  with  the  bark ;  that  being  effected  by  the  thick  and  fleshy  sheath  through  which  the 
radicle  is  protruded. 

The  union  between  the  sheath  and  bark  is  more  or  less  complete  in  different  specimens  that  I  have  examined, 
according  to  their  stage  of  growth.  At  Plate  CVI.  /.  9,  though  the  radicle  has  pierced  the  bark,  the  sheath 
had  hardly  united  with  the  edges  of  the  wound,  and  the  young  Myzodendron  was  removed  without  force  from  the 
Faff  us;  at  /.  10  the  union  is  complete,  probably  from  the  stem  of  the  Beech  being  younger,  and  affording  less 
resistance  to  the  attack,  and  lastly,  /  11  represents  a  still  more  close  union,  the  circumference  of  the  sheath 
passing  along  the  inner  walls  of  the  bark  and  its  revolute  edges,  thus  completely  enveloping  all  the  diseased  part. 

The  third  period  is  marked  by  the  exsertiou  of  the  plumule  from  a  dehiscence  of  the  two  coherent  cotyledons, 
the  consequent  elongation  of  the  ascending  axis  or  stem  of  the  Myzodendron,  and  the  deposition  of  the  liber  and 
scalariform  tissues  in  their  proper  positions  ;   a  process  I  have  never  had  the  opportunity  of  following. 

A  branch  attacked  by  the  Myzodendron  suffers  no  apparent  change  below  their  point  of  union,  but  all  beyond  it 
being  insufficiently  nourished,  does  not  increase  in  proportion,  and  after  a  time  dies  from  atrophy.  The  whole  juices 
of  the  branch  being  suddenly  arrested  at  its  abrupt  termination,  this  dilates  into  the  form  of  a  cup,  which,  from  the 
turning  of  the  Myzudendroti  towards  the  light  assumes  an  erect  position.  This  cup  (Plate  CVI./.  12)  is  more  or 
less  broad  (sometimes  three  inches  in  diameter)  and  shallow,  uniformly  covered  with  cuticle  and  bark,  and  has 
inflexed,  wrinkled  edges.  On  a  vertical  section  (Plate  CVII.  /  1)  it  is  seen  to  present  a  shallow,  conical  hollow, 
in  which  the  Myzodendron  rests,  and  to  be  formed  of  as  many  layers  of  wood  as  years  have  elapsed  since  the 
germination  of  the  parasite.  The  equally  expanded  base  of  the  latter  completely  fills  this  cup  in  the  form  of  a 
disk,  whose  edges  overlap  those  of  its  support,  and  swell  out  into  a  prominent  ridge  at  their  point  of  union.  At 
Plate  CVII.  /.  1,  a  vertical  section  of  the  cup  of  the  Beech  and  still  attached  disciform  base  of  the  Myzodendron 
is  given.  The  union  of  the  cellular  tissues  of  the  bark  of  the  two  is  very  intimate,  but  in  no  case  and  no  stage  of 
their  growth  have  I  been  enabled  to  trace  any  interlacing  of  then-  tissues,  or  any  union  of  the  one  with  the  other. 


FalMands,  efc]  FLORA  ANTARCTICA.  303 

The  woody  plates  of  the  various  branches  of  the  Myzodendron  all  meet  in  its  expanded  base,  and  are  there  strangely 
convoluted  and  contorted,  enclosing  masses  of  brown  and  dead  cellular  tissue,  probably  consisting  in  part  of  the 
alburnum  of  the  beech  deposited  there,  as  well  as  of  the  decayed  medullary  rays  of  the  Myzodendron.  Lower 
down,  the  woody  plates,  much,  reduced  in  size,  slightly  converge  and  meet  the  layers  of  wood  of  the  beech  ;  these 
may  perhaps  come  into  actual  contact,  but  generally,  if  not  always,  there  is  a  deposit  of  disintegrated  cellidar 
tissue  between  them.  The  Myzodendron,  having  finally  arrived  at  its  full  growth,  a  time  probably  coincident  with, 
if  not  dependent  upon,  the  period  when  the  Fayus  cannot  supply  it  with  sufficient  nutriment,  falls  away  and  leaves  a 
cup  still  attached  to,  or  rather  terminating  the  branch  of  a  Beech  (Plate  CVI.  /.  13)  whose  inner  surface  is 
channelled  with  radiating  fissures  and  these  again  crossed  by  the  concentric  rings  of  the  wood. 

This  process  of  germination  is  probably  similar  to  what  is  pursued  by  many  Loranthaceous  plants,  and  is 
rudely  represented  by  M.  Korthals,*  as  occurring  in  some  Javanese  species  of  this  Order. 

The  resemblance  between  the  sheathed  radicle  of  Loranthus  and  Viscum  and  a  coleorhiza  was  first  pointed  out 
by  Mn-belf,  but  hardly  admits  of  a  strict  comparison  of  this  order  with  EndorhizetE  in  this  respect,  any  more  than 
the  conferruniinated  cotyledons  of  this  species  are  to  be  compared  with  the  one  large  cotyledon  of  the  true  Mono- 
cofyledones,  for  in  Viscum  the  cotyledons  equally  enclose  a  cavity  containing  the  plumule,  though  they  are  not 
combined.  The  sheath  of  the  root  of  Loranthacece  appears  a  peculiar  organ,  especially  adapted  to  the  wants  of  the 
plants  in  which  it  occurs. 

So  very  highly  organized  a  nature  of  the  embryo  renders  it  probable  that  germination  takes  place  very  soon 
after  the  fall  of  the  seed,  or  perhaps  even  before.  It  is  remarkable  too,  that  the  operation  proceeds  in  summer 
and  exposed  to  the  full  light  of  day,  there  being  no  viscous  substance  to  protect  the  embryo.  I  have  described 
the  radicle  as  descending  from  the  seed  to  its  future  point  of  attachment,  but  here,  as  in  Viscum,  it  is  immaterial 
to  which  surface  of  the  branch  the  embryo  is  approximated,  the  radicular  extremity  being  invariably  directed 
towards  the  axis.  In  a  dried  specimen  of  M.  quadriforum  I  have  found  a  seedling  plant  fully  estabbshed  on  its  parent. 
The  frequent  ciu-ving  of  the  caulicule  also,  immediately  after  the  protrusion  of  the  radicle,  is  highly  curious,  the  seed 
being  loosely  suspended  by  its  filamentous  appendages,  and  thus  presenting  no  fulcrum  or  point  of  resistance,  in 
attempting  to  overcome  which,  such  a  flexure  might  be  induced.  It  is  worthy  of  remark  that  both  these  functions, 
so  closely  resembling  instinct  in  the  lower  animals,  are  characteristic  of  an  embryo  of  more  complex  structure 
than  any  with  which  I  am  acquainted. 

The  absorption  of  nourishment  from  the  albumen  takes  place  through  the  cotyledonary  extremity,  which  is 
retained  in  the  perisperm,  and  by  the  time  the  radicle  has  gained  the  bark  of  the  tree,  the  fecula  of  the  albumen 
is  wholly  absorbed.  This  transfer  of  nourishment  to  such  an  extent,  effected  simply  by  the  contact  of  two 
cellular  membranes,  only  one  of  them  being  endowed  with  life,  is  a  proof  that  in  vegetables  no  very  highly  com- 
plicated tissues  are  required  to  conduct  a  very  subtile  chemical  operation. 

The  bark  of  the  Beech  becomes  detached  from  the  subjacent  wood  prior  to  its  complete  penetration  by  the 
Myzodendron ;  the  intrusion  itself  is  by  no  means  a  mechanical  operation,  there  can  be  little  or  no  pressure  exerted 
by  an  embryo  suspended  as  tins  is,  it  must  be  effected  by  the  corrosion  of  the  cortex  which  simultaneously 
produces  a  separation  of  the  bark  from  the  wood,  materially  facilitating  the  progress  of  the  radicle. 

I  have  mentioned  that  the  duration  or  period  of  life  allowed  to  the  Myzodendron,  is  probably  determined  in 
some  degree,  by  the  effect  it  produces  on  the  plant  it  infests ;  the  latter  being  of  slower  growth,  is  sure  at  some 
period  to  rid  itself  of  the  intruder.   Thus,  the  weight  of  the  parasite  being  considerable,  and  exerted  upon  the  branches

it  weighs  them  down  and  checks  the  progress  of  the  sap,  upon  a  copious  supply  of  which  its  own  continued 
existence  depends.  This  remark  applies  to  many  parasites  which  attaching  themselves  to  the  younger  branches 
thus  commence  working  out  their  own  destruction  almost  from  the  earliest  stage  of  their  existence. 

The  open  cups  terminating  the  branches  of  Beech  trees,  similar  to  what  is  figured  at  Plate  CVT./.  13,  are 
frequently  to  be  met  wnth  in  the  woods  of  Fuegia,  and  mark  the  spot  where  one  of  these  curious  vegetables 
flourished ;  by  collecting  water  they  soon  decay,  and  the  branch  is  killed  below  for  some  little  distance,  but  the 
mischief  caused  by  so  large  a  parasite  is  after  all  very  insignificant,  and  what  no  healthy  Fagus  suffers  from. 

Myzodendron  brachystachyum  is  equally  abundant  in  Hermite  Island  with  M.  pmwtulatutn,  though  from  the 
colour  of  its  leaves,  resembling  the  common  forest  foliage,  it  is  by  no  means  so  conspicuous  an  object.  I  met  with 
the  male  plants  much  more  frequently  than  the  female.

In  the  first  part  of  this  work  (p.  37  in  obs.)  I  have  mentioned  how  closely  this  genus  is  allied  to  Euryhia  and 
to  Olearia,  agreeing  with  the  former  in  the  oblong  involucre  and  uniseriate  pappus,  and  with  the  latter  in  habit 
through  Olearia  oporiua  (0.  semidentata,  Decaisne  in  Voy.  Venus  ;  druica  oporina,Forst.).  It  diners  from  both 
in  the  presence  of  bnear  scales  occasionally  mixed  with  the  flowers  of  the  disc. 

The  present  is  the  tallest  dicotyledonous  plant  in  the  Falkland  Islands,  except  Feronica  elliptica,  which  is 
exceedingly  rare.     It  attains  a  height  of  about  4-5  feet,  and  forms  a  brushwood  along  the  banks  of  streams

Though  differing  from  the  C.  amelloides  in  habit,  and  especially  in  the  absence  of  ligulate  florets,  I  am  unable 
to  point  out  any  characters  that  will  separate  these  two  plants  generically ;  for  the  structure  of  the  involucre,  the 
occasional  linear  paleas  on  the  receptacle,  the  achasniuni,  the  pappus,  stamina  and  styles,  are  essentially  the  same. 

When  describing  the  Antarctic  species  of  Senecio  I  shall  allude  more  particularly  to  the  radiate  plants  of  that 
genus  being  natives  of  a  damp,  and  the  discoid  of  a  (bier,  climate.  The  same  remark  seems  to  hold  good  with 
Cliiliotrichum,  the  C.  amelloides  being  confined  to  the  humid  atmosphere  and  soil  of  the  Falkland  Islands  and 
Fuegia  ;  whilst  the  present,  and  two  allied  discoid  species,  (both,  however,  too  nearly  related  to  C.  humile),  of  which 
I  subjoin  descriptions*,  affect  the  arid  plains  of  Patagonia. 

C.  humile  is  also  a  native  of  Cape  Fairweather  on  the  east  coast  of  Patagonia.

under  the  equator,  by  Professor  Jameson,  whose  specimens  appear  to  differ  in  no  respect  from  those  gathered  in 
Fuegia. 

The  whole  plant  is  generally  perfectly  glabrous,  though  not  unfrequently  a  slight  pubescence  is  observable 
on  the  scales  of  the  involucre  in  individuals  collected  in  the  Falklands  and  Fuegia.  The  A.  Gilliesii  is  certainly  not 
distinct  from  this ;  both  have  the  flowers  of  the  ray  disposed  in  several  series  ;  but  otherwise,  and  especially  in  habit, 
they  agree  better  with  Aster  than  with  the  following  genus.

I  quite  believe  the  E.  alpinus  and  var.  uniform  of  Fuegia  to  be  identical  with  the  so-named  species  of  Em-ope 
and  North  America,  but  whether  they  may  not  be  in  both  countries  varieties  of  another  plant,  is  more  than  doubtful. 
Thus,  in  North  America  the  E.  alpinus  passes  at  once  and  unequivocally  into  a  species  called  E.glabratus,  winch  is  of  a 
totally  different  habit  and  appearance,  and  unites  the  alpine  plant  with  others  of  the  United  States.  So,  in  Europe, 
E.  alpinus  of  the  Altai  mountains  becomes  E.  elongatus,  in  which  the  pappus  is  about  one  half  longer  than  the 
acbeenium,  and  that  again  E.  glabratus,  whose  pappus  is  twice  as  long  as  the  achsenium.  Again,  I  have  seen 
specimens  of  this  species  from  the  Sierra  Nevada  of  Spain,  alt.  8,000  feet,  which  are  the  common  form  of  E.  alpinus, 
and  a  variety  gathered  at  1,000  feet  of  lower  elevation,  apparently  the  same  as  E.  acris ;  both  are  named  E.  alpinus 
by  M.  Boissier,  a  most  accurate  and  learned  European  botanist.  The  individuals  of  this  genus  are  apparently  in  the 
same  predicament  as  those  of  Epilobium,  a  form  from  one  country  often  constituting  the  link  that  unites  two  allied 
ones  of  a  remote  region,  insomuch  that  it  is  impossible  to  study  the  species  properly  without  an  examination  of 
individuals  from  all  parts  of  the  globe.  The  rapidity  with  which  an  Erigeron  may  be  dispersed  and  the  consequent 
facility  the  genus  affords  for  presenting  varieties,  are  evidenced  by  the  spread  of  E.  Canadensis,  L.,  throughout  the 
warm  countries  of  the  old  world,  since  the  discovery  of  the  new  ;  it  is  a  plant  which,  requiring  much  summer  heat, 
does  not  enter  into  the  Antarctic  regions,  though  abundant  in  Canada. 

The  variety  y  is  possibly  a  distinct  species,  but  my  specimens  are  very  imperfect,  and  the  E.  alpinus  itself  is  so 
variable  in  all  the  parts  of  the  world  it  inhabits  that  tins  may  be  a  state  of  it.  Capt.  King  has  what  I  consider  an 
intermediate  variety  from  Cape  Fan-weather,  on  the  coast  of  Patagonia,  which  in  hairiness  and  foliage  resembles 
E.  alpinus,  but  the  capitula  are,  as  in  var.  myosotifolius,  aggregated  at  the  apex  of  the  stem.

I  have  ventured  to  separate  this  from  the  former  because  of  its  broad  leaves  and  evident  petioles,  though  I  must 
confess  to  having  seen  specimens  from  Switzerland  of  E.  grandiflorus,  Hoppe,  a  variety  of  E.  alpinus,  in  which 
the  shape  of  the  foliage  very  closely  approaches  this.  It  bears  the  name  of  Capt.  Sidivan,  E.N.,  who  during  his 
several  visits  to  and  survey  of  the  coasts  of  the  Falkland  Islands,  formed  a  very  interesting  botanical  collection 

which  he  has  liberally  placed  in  my  hands  for  examination.

An  exceedingly  variable  species,  allied  to  E.  Canadensis,  though  with  much  larger  capitula.  The  var.  minor 
was  referred  in  the  work  quoted  (under  that  variety)  to  E.  Canadensis,  but  I  find  no  specimens  of  that  species,  either 
European  or  North  or  South  American,  to  vary  much  in  the  size  of  the  capitula.  The  variety  glabellus,  of  Hooker 
and  Arnott,  is,  I  think,  certainly  referable  to  E.  alpinus.

One  of  the  most  variable  and  abundant  of  South  American  plants,  from  the  latitude  of  Quito  to  the  Falkland 
Islands,  also  occurring  in  Brazil. 

I  am  inclined  to  consider  the  G.  spicatum  as  the  typical  form  of  a  species  to  which  G.  Americanum,  G.  purpu- 
reum, G.  Pennsylvanicum  (?),  and  probably  several  other  North  American  forms  should  be  referred,  and  from  which 
they  diifer  no  more  than  do  G.  strietum,  Norvegicum,  &c,  from  the  G.  sylvaticum  of  Europe.  Authentic  speci- 
mens of  G.  purpureum,  which  I  have  studied,  are  preserved  in  the  British  Museum,  with  Dillenius'  hand-writing 
attached  to  them,  and  they  accord  perfectly  with  the  figure  in  *  Hortus  Elthamensis.'  The  plant  is  common  in 
the  middle  and  southern  states  of  North  America,  and  is  very  evidently  a  variety  of  the  following,  G.  Ameri- 
canum, which  is  generally  more  branched,  with  broader  leaves  and  the  inflorescence  more  elongated.  It  is  a  species 
of  California  and  the  southern  United  States,  whence  I  have  examined  individuals  with  the  woolly  substance 
as  appressed  to  the  stem  and  under  side  of  the  leaves  as  in  many  Chilian  ones  of  G.  spicatum.  Bertero's  Chilian 
specimens  of  G.  Berteriawum  are  apparently  G.  purpureum,  between  which  and  G.  falcatum  (through  the 
varieties  of  the  latter  plant  enumerated  in  De  Candolle's  '  Prodromus')  there  seems  very  little  tangible  specific 
difference. 

An  examination  of  copious  suites  of  specimens  of  De  Candolle's  spicate  group  of  GnaphaUum  certainly  rather 
tends  than  otherwise  to  the  union  of  about  sixteen  species  which  it  contains  (as  conjectured  by  Hooker  and  Arnott 
in  the  'Botanical  Journal'),  and  to  reduce  them  to  perhaps  two,  one  of  them,  67.  sylvaticum,  being  European,  and 
the  other  (of  which  G.  spicatum  is  "the  type)  American.  Generally  speaking,  the  two  forms,  of  the  old  and  new 
world,  are  sufficiently  distinguishable  by  the  eye,  though  I  shoidd  feel  it  difficult  to  give  a  definition  of  either  that 
would  include  all  states  of  one  and  exclude  all  of  the  other.  If  future  observations  confirm  this  supposition 
a  question  will  arise  respecting  the  specific  name;  the  oldest,  or  Linnsean  (67.  purpureum)  applying  to  the 
variety,  if  that  be  called  variety  which  is  the  less  developed  state  of  a  plant  more  widely  diffused  under  another 
form.  The  trivial  appellation  of  67.  spicatum,  again,  though  not  botanically  speaking  strictly  correct,  is  charac- 
teristic of  all  the  aspects  of  both  the  European  and  American  plants,  and  that  of  G.  Americanum  appears  even 
more  suitable  to  a  plant  so  particularly  abundant  in  both  divisions  of  the  new  world.

I  have  refrained  from  uniting  the  present  with  the  foregoing  species,  being  unable  to  arrange  the  Chilian  forms 
of  this  genus  so  as  to  follow  the  transition  steps  by  which  they  pass  one  into  another,  without  even  a  fuller  series  of 
specimens  than  I  have  had  the  opportunity  of  consulting.  I  am  fully  satisfied  however,  that  neither  habit  of 
growth,  nor  foliage,  nor  inflorescence  affords  any  characters  to  separate  them.

This  appears  to  me  a  very  distinct  species  from  G.  spicatum  and  indeed  from  any  of  its  congeners,  and  may 
readily  be  recognized  by  its  small  size,  and  slender  nearly  leafless  flowering  stems,  whose  drooping  apices _bear  but  two 
or  three  capitida.  The  latter  are  elongated,  narrow,  and  their  scales  close  together  after  the  seeds  have  fallen, 
forming  an  acuminated  point  to  the  capitulum.

A  very  minute  species,  which  at  one  time  I  was  inclined  to  consider  a  seedling  state  of  G.  spicatum-,  but  the 
whole  plant  is  perfectly  glabrous,  the  stems  very  slender,  the  capitula  aggregated  at  the  apex  of  the  stem  and

Port  Gregory  is  described  as  surrounded  by  plaius,  which  are  covered  with  a  short  grass,  and  possess  nothing  but 
a  herbaceous  vegetation.  These  features  are  so  different  from  those  of  Port  Famine,  that  should  the  Senecio  Arnottii 
be  identical  with  S.  kmgipes,  and  the  latter  be  transported  to  this  locality,  the  appearance  it  would  probably  assume 
is  that  of  8.  miser.  That  such  may  be  the  origin  of  the  present  plant  is  rendered  still  more  likely,  from  an  exami- 
nation of  Mr.  Darwin's  specimens  of  S.  tricuspidatus,  Hook.,  a  discoid  species,  hitherto  only  gathered  high 
up  the  river  Santa  Cruz  in  Patagonia.  Mr.  Darwin  labels  two  very  different  looking  individuals  as  belonging 
to  this  same  species,  the  one  large  and  leafy,  with  leaves  broadly  linear,  dilated  and  deeply  trifid  at  the  apex, 
fully  an  inch  or  an  inch  and  a  quarter  long,  and  the  whole  plant  equally  luxuriant  with  S.  Arnottii,  the  other, 
again,  has  the  squalid  habit  of  S.  miser,  and  foliage  very  simdar  in  size,  shape  and  texture.  Nor  is  it  in  habit 
and  foliage  alone  that  the  Seneciones  are  liable  to  vary.  The  difference  between  some  of  the  discoid  and  radiate 
species  is  almost  confined  to  the  presence  or  absence  of  a  ray,  and  this  is  so  remarkably  the  case,  that  I  have 
found  an  analogue  to  almost  all  the  discoid  species  described  above,  amongst  the  radiate,  and  MM.  Hombron  and 
Jacquinot  figure  a  Magellanic  species  bearing  both  radiate  and  discoid  flowers  on  the  same  specimen.  Now  since  the 
S.  Jacobaa  of  England,  and  other  European  species,  vary  in  having  or  wanting  the  ligulate  florets,  so  may  these  of 
Patagonia  and  Fuegia,  and  thus  still  further  reduce  the  number  of  species. 

It  is  worthy  of  observation  that  the  discoid  Seneciones  are  almost  peculiar  to  the  drier  soil  and  climate  of  Eastern 
Patagonia  and  Fuegia,  only  one  (S.  candidans),  an  inhabitant  of  sandy  places,  being  a  Fuegian  and  Falkland  Island 
species.  I  am  not  prepared  to  say  how  far  this  favours  the  supposition  that  the  absence  of  a  ray  may  be 
due  to  causes  now  in  operation,  but  the  same  remark  applies  to  a  certain  extent  to  the  Seneciones  of  other  countries, 
and  to  the  geuus  ChiUotrichum  in  Antarctic  America. 

There  are  several  points  connected  with  this  genus  of  a  much  more  interesting  nature  than  the  variation 
of  its  Protean  species;  such  as  the  absence  of  characters  in  the  species  indicating  natural  groups;  the  scarcity  of 
the  species  in  Australia,  which  contains  scarcely  seventy,  contrasted  with  their  abundance  in  the  Cape  which  pos- 
sesses nearly  two  hundred ;  then-  absence  in  the  Antarctic  Islands  south  of  New  Zealand,  and  then'  forming  upward  s 
of  twice  the  largest  genus  of  flowering  plants  in  the  flora  of  Fuegia  and  Patagonia.  A  still  more  singular  fact  is 
the  confined  range  *  of  the  individual  species,  though  belonging  to  one  of  the  very  largest  genera  that  has  an 
universal  diffusion.  Thus  out  of  the  twenty-one  species  to  be  enumerated  in  the  present  part,  not  one  inhabits  any 
other  country  but  extra-tropical  South  America,  except  the  introduced  S.  vulgaris.  If  the  species  are  to  be  consi- 
dered the  offspring  of  variation,  there  must  be  allowed  to  Senecio  what  may  be  called  a  disposition  to  vary 
centrifugally,  that  causes  the  individuals  to  depart  further  and  further  from  an  original  one  in  proportion  as  the 
genus  spreads  over  the  earth's  surface.  There  is  not  with  Senecio,  as  with  the  equally  widely  dispersed  Gnapha- 
lium,  that  tendency  in  the  forms  all  countries  present,  to  revert  to  a  few  typical  species.  The  fact  of  the  species  of 
Senecio  in  each  separate  country  being  almost  inextricable,  may  be  cited  in  favour  of  variation  as  an  agent  producing 
what  other  naturalists  suppose  original  creations.  Against  this  hypothesis,  however,  it  might  be  urged,  that  the 
S.  vulgaris  has  shewn  no  tendency  to  vary  during  the  eighty  years  which  have,  in  all  likelihood,  elapsed  since  its 
first  importation  into  the  Falkland  Islands. 

*  This  is  the  more  remarkable,  for  Senecio  thus  forms  an  exception  to  a  very  prevailing  law  in  the  animal  and 
vegetable  kingdoms,  (first  pointed  out  to  me  by  my  friend  Mr.  Darwin),  that  the  individual  species  of  large  and 
widely  diffused  genera  have  generally  themselves  very  wide  ranges.

it  is  however  abundantly  distinct,  especially  in  its  frutescent  habit,  aud  the  broader,  lanate  and  blunter  leaves.  Whether 
it  be  really  different  from  the  three  following  species  is  much  more  questionable  ;  I  am  inclined  to  think  it  is  not, 
however  great  their  dissimdarity  in  habit.  It  differs  again  from  the  discoid  S.  Patagonicus,  only  in  the  presence 
of  a  ray  and  the  peduncles  being  solitary.  I  am  doubtful  whether  the  figure  of  MM.  Hombron  and  Jacquinot 
refers  to  this  plant,  their  specimens  are  from  the  Strait  of  Magalhaens.

As  is  stated  under  the  S.  FalMandicus,  the  varieties  a  and  /3  of  S.  littoralis  belong  to  two  very  different 
species.  The  one  for  which  I  have  retained  the  name,  is  generally  a  maritime  plant,  usually  growing  in  marshy 
places  and  never  altogether  woolly,  or  more  so  in  its  youngest  state  than  when  older.  The  leaves  are  extremely 
variable,  straight  or  falcate,  obtuse  or  generally  acute,  one  line  to  nearly  one  third  of  an  inch  broad,  strictly  linear 
or  obovato-lanceolate,  sometimes,  though  rarely,  obscurely  siuuato-dentate.

A  fully  grown  plant  of  this  is  very  handsome ;  I  possess  a  specimen  only  a  foot  high,  and  with  a  simple  stem, 
though  branching  so  copiously  above  as  to  bear  upwards  of  a  hundred  flowers,  all  fully  blown  and  each  nearly  an 
inch  and  a  half  in  diameter.

A  very  handsome  and  singular  plant,  almost  confined  to  the  "  Streams  of  stones,"  which  are  those  curious 
tracts  of  land  covered  with  loose  blocks  of  quartz,  abounding  in  some  parts  of  the  Falkland  Islands.  There  the 
Nassauvia  serpens  grows,  sending  its  brittle  stems,  several  fathoms  long,  down  amongst  the  masses  of  rock,  till  they 
reach  the  soil,  often  at  a  considerable  depth.  The  plant  varies  somewhat  in  the  foliage,  the  leaves  being  suberect 
or  recurved,  and  more  or  less  silky.

In  general  appearance  the  present  plant  so  closely  resembles  N.  Gaudichaudii,  that  at  first  sight  it  is  difficult 
to  distinguish  them.  Cassini  describes  the  flowers  as  apparently  yellow ;  but  Mr.  Anderson,  who  collected  the 
plant  during  Capt.  King's  voyage,  mentions  that  they  are  white.  The  genus  Triachne,  remarks  De  Candolle, 
hardly  differs  from  Nassauvia,  nor  can  I  find  any  character  by  which  to  separate  them.

especially  of  South  Chili  and  Patagonia ;  they  do  not  cross  the  Strait  of  Magalhaens  on  the  western  side,  but  on

Rather  a  variable  plant  in  size,  in  the  glandular  pubescence,  in  the  number  and  size  of  the  spinulse  on  the 
leaves,  which  are  iu  a  single  or  double  row,  in  the  sharpness  or  bluntness  of  the  leaves,  and  somewhat  also  in  the  form 
of  the  involucral  scales.  It  is  one  of  the  most  interesting  plants  of  the  Falkland  Islands  from  the  very  sweet  scent 
of  its  large  pale-blue  flowers,  which  has  been  compared  to  Jessamine  and  to  Violets  ;  it  generally  grows  near  the 
sea  in  rocky  places,  and  has  also  been  found  on  the  S.E.  coast  of  Patagonia.  The  H.  Beckii  (Perezia,  Hook, 
et  Am.)  of  Patagonia  is  very  nearly  allied  to  this,  but  readily  distinguished  by  the  longer  spinulose  apex  of  the 
narrower  leaves,  and  the  recurved  lower  scales  of  the  involucre.  The  leaves  of  the  latter  are  exceedingly  variable, 
sometimes  wholly  without  marginal  spinuke,  at  others  crested  with  white  equidistant  spinules  much  longer  than  those 
of  H.  ecJiinulatus.

This  again  is  a  highly  variable  plant,  the  majority  of  the  Falkland  Island  specimens  scarcely  agreeing  with 
Gaudichaud's  description  (as  given  in  Freycinet's  Voyage),  in  which  the  peduncles  are  said  to  be  elongated  and 
branched,  though  in  the  notes  on  the  species,  M.  Gaudichaud  states  that  they  are  either  branched  or  simple. 
Small  specimens  entirely  coincide  with  D'Urville's  character  of  if.  minima?  Willd.  The  other  species  of  this  genus, 
as  H.  apargioides,  and  H.  taraxacoides,  are,  however,  so  variable  that  the  character  of  the  single  or  many-flowered 
peduncle  loses  its  value  as  a  mark  whereby  to  distinguish  them.

Since  the  publication  of  the  synopsis  of  this  genus,  in  the  first  part  of  the  present  work,  I  have  examined  a 
new  species  from  the  Straits  of  Magalhaens,  also  inhabiting  the  eastern  side  of  the  Andes  of  Chili,  specimens  of  which, 
from  the  latter  locality,  were  then  considered  to  be  the  true  P.  repens,  which,  so  far  as  I  am  aware,  is  a  native 
of  the  Falkland  Islands,  Staten  Land,  and  Valparaiso  only.

voyagers,  throughout  that  country. 

One  of  the  most  abundant  of  Puegian  plants,  exceedingly  variable  in  the  size  of  its  foliage.  Owing,  apparently, 
to  the  puncture  of  an  insect,  the  apices  of  the  raniuli  in  the  present  and  following  species  frequently  assmne  the 
form  of  cones,  being  covered  with  densely  imbricated  leaves  so  metamorphosed  as  exactly  to  resemble  the  scales  of 
an  Abies. 

Though  Protean  in  its  fobage,  this  species  is  very  confined  in  its  geographical  limits,  advancing  no  further 
north  than  Cape  Fairweather,  on  the  east  coast  of  Patagonia.

The  two  plants  here  united  under  one  specific  name  are  decidedly  mere  varieties.  The  0.  empetrifolia  is  by  far 
the  most  abundant,  and  its  prostrate  stems  sometimes  attain  the  length  of  two  feet.     Var.  minor,  in  its  smallest

state,  appears,  at  first  sight,  sufficiently  distinct ;  but  it  often  runs  out  to  a  considerable  length,  when  the  leaves 
become  much  more  laxly  imbricated. 

Both  pink  and  white  berries  are  found  on  this  species  ;  also  cones,  similar  to  those  described  under  P.  mucro- 
nata,  and  diseased  ramuli,  densely  covered  with  minute,  erect,  linear  leaves. 

Dr.  Gillies'  Arbutus  vaccinioides,  from  the  Andes  of  Chili,  which  appears  identical  with  Poeppig's  A.  leucocarpa 
{Pernettya,  DC),  is  most  likely  another  form  of  this  plant,  the  length  of  the  pedicels  affording  no  character  either 
in  the  flower  or  fruit.

Pernettya  serpyllifolia,  DC,  and  Arbutus  serpyllifolia,  Lam.,  all  which  names  must  yield  to  that  of  G.  microphylla, 
the  plant  being  undoubtedly  the  little-known  Arbutus  microphylla  of  Forster.

It  is  certainly  very  remarkable  that  the  sole  American  representative  hitherto  noticed  of  the  order  Epacridea>, 
is  also  among  the  very  few  that  so  deviate  from  one  of  the  most  important  diagnostic  characters  of  that  order,  as  to 
present  a  distinctly  two-celled  anther.     Labillardiere  rightly  described  the  stamens  of  the  Tasmanian  Prionotes 


328  FLOKA  ANTARCTICA.  [Fuec/ia,  the 

cerudhoides,  Br.,  as  having  this  structure,  and  it  is  a  singular  circumstance  that  these  two  plants,  which,  through 
their  bilocular  anthers  and  hypogynous  filaments,  completely  unite  the  Ericea  of  the  northern  hemisphere  with  their 
southern  representatives  in  Australia,  the  Epacridea:,  are  both  natives  of  very  humid  climates  and  densely  wooded 
regions,  and  not  of  such  localities  as  the  majority  of  cither  Order  (but  especially  the  Epacridea)  affect. 

The  subscandent  habit  of  L.  Amerieanus  is  very  peculiar ;  it  grows  on  the  trunks  of  trees,  and  often  creeps  up 
them  for  some  feet.  This  is  also  the  case  with  some  other  distichous-leaved  Antarctic  plants,  as  Callixene,  and 
Lusuriaga,  and  with  the  Prionotes  and  Decaspora  of  Tasmania.

The  true  Potato  plant  reaches  the  boundary  to  which  the  Antarctic  Flora  of  South  America  is  confined,  and  is 
described  as  particularly  abundant  in  the  locabties  whence  Mr.  Darwin's  specimens  were  brought.  The  nature  of  the 
present  work  forbids  my  dwelling  on  some  of  the  peculiarities  which  mark  the  history  and  habitat  of  this  plant ;  and 
I  leave  the  subject  with  the  less  reluctance,  because  Mr.  Darwin's  own  history  of  its  discovery  in  an  indisputably 
native  state  is  already  pubbshed  in  one  of  the  most  interesting  '  Journals  of  a  Naturahst '  that  has  ever  been 
written.  The  following  remarks  apply  wholly  to  the  botanical  affinities  of  the  individual  species  now  universally 
cultivated  in  all  temperate  civilized  countries. 

There  are  in  South  America  several  Solatia,  so  closely  allied  to  the  true  Potato,  that  it  is  exceediugly  difficult 
to  distinguish  them  specifically.  Though  differing  materially  in  the  shape  of  their  calycine  lobes,  they  display  such 
variation  in  these  organs,  that  no  specific  value  can  be  attached  to  them  alone.  The  fruit  may  afford  better  charac- 
ters, but  that  of  many  is  at  present  unknown.  The  following  is  an  enumeration  of  those  South  American  Solatia, 
allied  to,  or  varieties  of,  the  true  S.  tuberosum,  which  exist  in  the  Hookerian  Herbarium.  I  shall  commence  with 
the  specimens  most  similar  to  the  common  cultivated  form.

I  think  there  can  hardly  be  a  doubt  that  the  largest-flowered  plant,  whose  varieties  I  have  included  under  the 
Stirps  I.,  is  the  true  cultivated  Potato,  a  species,  in  its  wild  state,  confined  to  the  west  of  the  Andes.  Whether  the 
&  Commersonii,  which  chiefly  differs  in  the  size  of  the  flowers,  be  really  distinct  or  not,  is  another  question.  Ranging 
as  as  it  does  from  one  side  of  the  contineut  to  the  other,  it  may  perhaps  have  some  claims  to  be  considered  the  type 
of  the  Potato,  of  which  the  large-flowered  variety,  now  commonly  cultivated  with  us,  is  confined,  as  just  observed; 
to  the  Pacific  side  of  South  America. 

That  both  produce  tubers,  called  "  Papas  "  and  "  Maglia,"  is  evident,  for  the  specimen  from  which  the  tubers 
were  reared  to  the  size  of  ordinary  Potatos,  in  the  Horticultural  Society's  Gardens,  is  certainly  referable  to  the 
small-flowered  Valparaiso  plant,  also  collected  by  Bridges ;  and  the  large-flowered  species  of  Lima  presents  the 
ordinary  varieties  of  the  well-known  vegetable,  as  does  the  Chouos  Arcliipelago  and  Mendoza  one. 

To  show  how  little  evidence  is  to  be  derived  from  the  mere  fact  of  the  species  producing  tuberous  roots,  I  may 
mention  that  there  is  a  third  plant,  allied  to  both  the  former,  and  found  over  a  great  part  of  extra-tropical 
South  America,  bearing  tubers,  altogether  similar  to  those  of  the  two  foregoing  Solatia.  This  I  refrain  from 
naming,  though  unable  to  ascertain  that  it  is  previously  described,  but  it  may  readily  be  recognized  by  its  great 
general  resemblance  to  S.  Commersonii,  from  which  it  differs  in  the  small  fruit,  and  in  the  short  cupuliform  or 
hemispherical  calyx,  whose  lobes  are  short,  broad,  and  rounded  ;  while  in  other  respects,  as  regards  pubescence  and 
size  and  form  of  the  leaflets,  it  is  as  variable  as  the  two  former.  I  have  seen  specimens  from  Antueo  {Reynolds), 
Valdivia  {Bridges,  719),  Valparaiso  {Cuming,  555),  and  Uraguay  {Tweedie),  to  the  last  of  which  the  collector  has 
added  ou  the  ticket,  "  This  bears  a  considerable  quantity  of  nasty  soft  watery  Potatos  at  its  root,  called  Papas 
Amargas,  in  consequence  of  their  bitter  taste." 

With  regard  to  Mr.  Darwin's  specimens,  in  producing  an  abundance  of  tubers  they  only  follow  the  habit  of 
Cardamine  liirsuta  and  many  other  plants,  when  inhabiting  such  a  soil  as  a  shingly  beach.  In  the  absence  of  a  bitter 
principle,  evident  in  the  wild  tubers  of  the  "  Maglia  "  of  the  drier  parts  of  South  America,  the  Chonos  Archipelago 
Potato  may  be  compared  with  the  Celery  meutioned  at  p.  287,  whose  insipidity  I  attribute  partly  to  the  dampness 
of  the  climate,  and  still  more  to  the  absence  of  the  direct  rays  of  the  sun. 

Professor  Henslow,  who  has  investigated  the  subject  of  the  native  Potato  with  his  usual  care  and  skill,  agrees 
with  me  in  considering  this  of  Mr.  Darwin's  to  be  quite  identical  with  the  common  cultivated  Potato ;  and  he  further 
remarks  the  differences  between  it  and  the  "  Maglia  "  of  Chili,  without,,  however,  pronouncing  them  specifically 
distinct. 

Thus,  from  the  information  I  have  been  able  to  obtain,  it  appears  very  possible  that  the  plant  experimented  upon 
in  the  Horticultural  Society's  Gardens,  is  even  specifically  distinct  from  the  common  cultivated  Potato,  for  it  is  cer- 
tainly  the  small-flowered  "  Maglia  "  of  Chili,  and  not  the  large-blossomed  "Aquinas"  of  Chiloe  and  the  Chonos 
Archipelago.  It  woidd  be  very  interesting  to  introduce  the  tubers  of  Mr.  Darwin's  S.  tuberosum,  and  the  S.  Com- 
mersonii (the  latter  both  from  the  east  and  west  coasts),  into  our  gardens ;  along  with,  if  possible.the  short-calyxed 
species,  winch  is  also  stated  by  Mr.  Tweedie  to  produce  tubers. 

Though  I  have  spoken  of  these  three  Solana  as  all  tuberous-rooted,  it  is  more  than  probable  that  they  are  not 
always  or  necessarily  so,  and  that  the  absence  of  those  hybernacula  does  not  indicate  specific  distinction.  Mr. 
Cruikshanks,  who  has  studied  one  of  the  above  species  in  its  cidtivated  state  in  Chili  (probably  the  S.  Commersonii), 
says  of  it,  that  the  "  Papas  Amarillas,"  or  Yellow  Potato  of  Peru,  which  was  grown  in  the  Horticultural  Society's 
Gardens,  is  a  variety  of  the  Solatium  tuberosum,  differing  from  all  other  known  varieties  of  that  species  in  its  partiality 
for  a  particular  climate.  Mr.  Cruikshanks  also  remarks,  "  that  it  will  not  produce  bulbs  near  the  coast  in  Peru, 
nor  at  Valparaiso,  but  only  on  the  higher  parts  and  in  a  very  few  spots ;  but  that  further  south  in  Chili,  as  near 
Valdivia,  it  is  very  productive."  The  explanation  seems  to  be,  that  this  yellow  Potato,  whether  a  species  or  variety, 
is  dependent  upon  a  moist  and   cool   climate   for  the   formation  of  tubers,  or,  as  the  inhabitants  of  Peru  express

it,  on  the  "  tiemperamento  de  la  Sierra".  Hence,  too,  may  arise  their  absence  on  Dr.  Lindley's  S.  etuberosum, 
which  is  intermediate  between  two  of  Mr,  Mathews'  Peruvian  states  of  S.  tuberosum,  having  the  foliage  and  colour  of 
the  flowers  of  his  No.  847,  which  I  have  made  the  second  variety  of  8.  tuberosum,  and  the  smooth  panicle  and 
small  calyx  of  Mathews'  No.  771,  or  my  fourth  variety  of  the  same  species.

Much  has  been  written  regarding  the  affinities  of  this  curious  genus  ;  for  several  reasons,  I  retain  it  near 
Solanece,  to  which  Order  it  was  doubtfully  referred  by  the  authors  of  the  "  Plantes  .Equinoctiales,"  and  more  recently 
by  M.  Endlicher.  M.  Kunth  afterwards  suggested  its  relationship  with  TheophrastetB,  which  Mr.  Don  had  also  sus- 
pected. The  last-mentioned  author  has  more  recently  arranged  it  in  Gentianece,  and  is  followed  by  Dr.  Lindley,  in 
'  The  Vegetable  Kingdom  ',  who  had  previously  placed  it  in  AquifioliaceaJ  (Xat.  Syst.  of  Bot.).  My  own  impression  is 
that  its  proper  place  is  nearer  to  the  order  Ericea,  an  hypothesis  strengthened  by  the  observations  of  my  friend 
M.  Planchon,  who  has  studied  this  plant  most  attentively,  and  who  pointed  out  its  affinity  with  the  anomalous  genus 
Galax,  and  particularly  with  the  Arctic  European  and  American  Diapensia  Lapponica,  in  the  position  of  the  anther 
and  some  other  points. 

Capt.  King's  collection  contains  a  very  curious  plant  from  Port  Famine,  which,  from  the  nature  of  the  fruit 
and  testa  of  the  unripe  seeds,  I  presume,  approaches  Ericea,  though  wholly  differing  in  habit  and  in  some  other 
points  which  ally  it  to  Diapensia.  Unfortunately  all  the  specimens  are  out  of  flower,  which  I  exceedingly  regret, 
for  it  may  afford  characters  which  will  throw  a  light  upon  these  and  other  obscure  genera  of  Monopetalea.  Its 
seeds  are  enclosed  in  a  double  testa,  a  structure  which  occurs,  though  rarely,  in  several  orders  of  monopetalous 
Dicotyledons. 

The  geographical  distribution  of  this  curious  genus  is,  like  that  of  Gunnera,  very  extended,  from  the  Andes 
under  the  equator,  alt.  12,000  feet,  to  the  level  of  the  sea  at  Staten  Island,  in  lat.  53°  south.

associates  as  the  present,  or  the  nodding  bells  of  the  Sisyrinchium,  which  sometimes  whiten  the  plains,  or  the  deep-

form  as  in  a  Cape  Fairweather  individual  of  C.  nana,  and,  though  more  glabrous  than  in  most  states  of  the  latter 
plant,  they  are  not  universally  so ;  the  corolla;  are  quite  alike  in  the  two,  and  the  difference  in  the  length  of  the

Very  abundant  between  the  latitude  of  Valparaiso  and  the  Strait  of  Magalhaens,  though  confined  to  a  narrow 
belt,  which  runs  obliquely  across  the  continent  of  South  America,  from  lat.  33°,  to  lat.  53°.  In  the  northern  half  of 
its  range,  between  the  parallels  of  Valparaiso  and  Chiloe,  it  is  chiefly  confined  to  the  west  of  the  Andes ;  in  the 
southern  half,  between  the  latter  locality  and  the  Strait  of  Magalhaens,  it  crosses  to  the  east  side  of  South  America ; 
thus  avoiding  equally  the  wet,  cold,  and  stormy  latitudes  of  South-west  Chili  and  Fuegia,  and  the  arid  plains  of 
Patagonia.

Hab.  Falkland  Islands,  Gaudichav.d,  J.  D.  H.     Kerguelen's  Land,  /.  D.  H. 

I  am  convinced  there  is  no  specific  distinction  between  the  Limosella  aquatica,  L.,  and  L.  tenuifolia,  Nutt.,  and 
have  consequently  united  them.  In  the  specimens  from  the  southern  hemisphere  which  I  have  examined,  the  leaves 
do  not  attain  the  breadth  which  those  of  the  northern  temperate  regions  generally  present ;  though,  on  the  other 
hand,  both  European,  Asiatic,  and  North  American  plants  of  the  L.  aquatica  have  the  foliage  narrow  as  that  of 
L.  tenuifolia,  to  which  variety  some  Arctic  individuals  of  L.  aquatica  are  quite  simdar. 

The  range  of  this  species  is  nearly  identical  with  that  of  Callitriche  aquatica  and  Montia  fontana,  and  there  is 
also  a  considerable  resemblance  in  the  mode  and  extent  of  their  variation  between  these  three  plants.  This  is  not 
remarkable  with  regard  to  Callitriche  and  Montia,  which  are  very  frequently  seen  associated  together,  invariably  so 
in  Kerguelen's  Land,  in  the  Falkland  Islands,  in  Lord  Auckland's  Group  and  Campbell's  Island,  and  thus  are  influ- 
enced in  common  by  every  fluctuation  of  climate  and  temperature,  and  by  the  depth  or  rapidity  of  the  current, 
when  growing  in  the  water ;  but  the  Limosella  does  not  occur  mixed  with  these  two  genera,  even  though  inhabiting 
the  same  islands. 

In  Kerguelen's  Land  the  Limosella  is  found  in  the  muddy  bottom  of  a  lake,  and  probably  flowers  all  the  year 
round.  I  gathered  it  in  the  month  of  July  (mid-winter),  beneath  two  feet  of  water,  covered  with  two  inches  of  ice ; 
even  then  it  had  fully-formed  flowers,  whose  closely  imbricating  petals  retained  a  bubble  of  air,  the  anthers  were  full 
of  pollen  and  the  ovides  apparently  impregnated.  The  climate  of  Kerguelen's  Land  being  such,  that  this  lake  is 
perhaps  never  dried,  it  follows  that  the  plant  has  here  the  power  of  impregnation  when  cut  off  from  a  free  communi- 
cation with  the  atmosphere,  and  supplied  with  a  very  small  portion  of  atmospheric  air  generated  by  itself.  My 
Falkland  Island  specimens  are  in  a  very  poor  state.  Gaudichaud,  who  first  detected  it  in  that  Island,  considers  it 
identical  with  the  European  plant.

probably  introduced  originally  from  Europe  into  the  Falkland  Islands.  It  is  found  no  where  else  in  the  southern

This,  of  which  I  have  seen  but  a  single  specimen,  must  be  one  of  the  handsomest  Fuegian  plants ;  it  is  appa-

A  plant,  so  very  closely  resembling  the  S.  sylvatica,  L.,  of  Great  Britain,  that  I  long  hesitated  on  the  propriety 
of  erecting  it  into  a  new  species,  but  do  so  in  concurrence  with  the  opinion  of  Mi-.  Bentham.  Mr.  Watson,  also, 
upon  whose  thorough  knowledge  of  British  plants,  in  all  their  exotic  forms  to  which  he  has  had  access,  the  greatest 
reliance  may  be  placed,  has,  with  his  usual  kindness,  given  much  attention  to  the  present  plant,  and  sums  up  the 
differences  between  it  and  European  S.  sylvatica,  in  the  leaves  of  the  latter  not  being  so  obtuse  nor  so  obtusely 
serrate,  and  in  the  lateral  lobes  of  the  lower  lip  of  the  corollas  being  more  deeply  divided.  The  leaves  of  the 
European  S.palustris,  L.,  however,  he  adds,  vary  from  very  acutely  to  quite  as  obtusely  serrate. 

Not  being  versed  in  the  whole  genus  Stachys,  which  contains  upwards  of  one  hundred  species,  I  was  inclined 
to  regard  this  plant  as  possibly  intermediate  between  the  S. sylvatica  of  Europe,  and  S.  Macrai  of  Chili.  Mr.  Bentham, 
however,  entirely  dissents  from  such  an  opinion  after  a  most  careful  review  of  its  characters,  and,  I  need  hardly  add, 
that  on  his  knowledge  and  experience  we  may  rely  for  the  validity  of  the  species.

The  excellent  plate,  executed  for  this  work  by  Mr.  Fitch,  enables  the  British  botanist  to  form  a  just  idea  of  the 
Antarctic  state  or  variety  of  P.  farinosa,  L. ;  which,  it  will  be  seen,  differs  from  the  majority  of  those  of  Britain  in 
the  short  peduncles  of  the  white  flower,  in  the  position  of  the  stamens,  in  the  tube  of  the  corolla,  and  in  the  colour 
of  the  flowers.  The  first  of  these  characters  is  constant  in  all  the  Falkland  Island  and  Magellanic  specimens  of  this 
species,  but  is  also  seen  in  an  individual  of  P. farinosa,  gathered  near  Settle  in  Yorkshire  by  Mi-.  Tatham,  for  which 
I  am  indebted  to  my  friend  Mr.  Watson,  who  not  content  with  examining  this  plant  with  me,  had  the  kindness  to 
collate  a  suite  of  Antarctic  specimens  with  many  hundreds  of  British  growth.  The  result  of  this  examination  has 
been,  that  except,  perhaps,  the  colour  of  the  flower,  there  is  no  constant  character  to  distinguish  the  races  of  the 
opposite  hemispheres,  neither  the  length  of  the  pedicels,  of  the  calycine  segments,  of  the  tube  of  the  corolla,  nor 
the  position  of  the  stamens  in  the  latter.  If,  again,  we  grant  (with  M.  Duby)  that  the  P.  Scotica,  Hook.,  is  not 
even  a  variety  of  P. farinosa,  the  length  of  the  pedicel  is  of  still  less  value,  for  the  North  Scottish  individuals  are 
undistinguishable,  except  by  the  colour  of  the  corolla,  from  specimens  of  var.  (i,  gathered  at  Cape  Horn  by  myself, 
and  on  Mount  Tarn  on  the  north  shore  of  the  Strait  of  Magalliaens,  by  Mr.  Darwin,  these  localities  being  the 
northern  and  southern  extremes  of  its  range  in  the  Southern  Hemisphere. 

Lastly,  on  comparing  var.  fl  with  foreign  examples  of  P.  farinosa,  their  identity  is  still  more  evident ;  for  the 
latter  attain  the  same  great  size  in  Austria  that  the  var.  /3  often  does  in  the  Falkland  Islands,  whilst  Arctic  American 
specimens  of  the  two  are  entirely  alike. 

One  argument  which  militates  against  the  common  origin  of  the  individuals  from  the  opposite  hemispheres, 
must  not  be  overlooked ;  it  is  the  absence  of  the  plant,  and,  indeed,  of  the  whole  genus,  in  any  part  of  the  Andes 
south  of  39°  north  lat.;  a  circumstance  which  makes  it  very  difficult  to  account  for  its  appearance  in  the  two 
opposite  temperate  zones,  if  all  the  individuals  of  both  hemispheres  are  supposed  to  have  sprung  from  one  parent.

338  FLORA  ANTAECTICA.  [Fuegia,  the 

It  appears  to  me  that  two  very  distinct  species  of  this  genus  have  heen  confounded,  partly  together,  and  partly 
with  the  A.  tenella,  L.,  of  Europe.  The  first  is  confined  to  the  damp  western  portions  of  middle  and  southern 
Chili,  Fuegia,  and  the  Falkland  Islands,  and  there  are  two  or  perhaps  three  varieties  of  it ;  I  take  it  to  be  the 
A.  alternifoUa  of  Cavanilles,  a  variable  plant,  with  the  peduncles  of  the  same  length  as,  or  not  much  exceeding,  the 
leaves,  and  the  capsule  shorter  than  the  calyx.  The  figure  of  that  author  is  very  inaccurate  and  at  variance  with  his 
description  ;  for  the  plant  is  represented  erect,  instead  of  creeping,  and  the  leaves  scattered,  though  said  to  be,  approxi- 
mate. Supposing  Cavanilles'  plant  to  form  one  variety  of  A.  alternifoUa,  a  second  is  larger  and  also  creeping,  with 
prostrate  branches,  8-10  inches  long,  bearing  broader,  rounded  and  more  acute  leaves;  it  has  been  collected  in 
Valparaiso  by  Mr.  Cuming  and  Mr.  Bridges.  A  third,  intermediate  between  this  and  the  Fucgian  form,  has  the 
leaves  more  crowded,  ovate-oblong,  and  smaller ;  it  is  possibly  the  state  figured  by  Cavanilles,  and  has  been  gathered 
at  Concepeion  by  Capt.  King,  at  Valdivia  by  Mi-.  Bridges,  and  on  the  Andes  of  Mendoza  by  Dr.  Gillies  (Ruellia 
caspitosa,  Gill.  MSS. ;  and  Anagallis  herpestoides,  Gill.  MSS.).  The  fourth  variety  is  what  I  have  called  densifolia  ; 
its  leaves  and  stem  are  much  smaller  and  crowded,  and  the  whole  plant  is  succulent. 

Another  extra-tropical  South  American  Anagallis  is  the  A.jiliformis,  Link,  {A.  tenella,  fj.Jilifonuis,  St.  Hil.), 
which  approaches  A.  tenella  so  very  closely,  that  M.  St.  Hilaire  has  united  them  specifically.  It  differs  from 
A.  alternifoUa  in  the  leaves  being  opposite,  the  stem  slender,  the  peduncles  longer,  the  calycine  pieces  narrower  and 
twice  as  long  as  the  capsule,  and  the  whole  plant  not  so  succulent ;  from  the  European  A.  tenella  in  the  leaves  never 
being  so  broad,  in  the  longer  peduncles  and  rigid  stems. 

The  variety  densifolia  has  a  large  capsule,  always  equalling  the  calyx  in  length,  thus  differing  from  the  plant 
figured  by  Cavanilles.  The  capsule,  though  described  by  D'Urville  as  having  the  dehiscence  of  a  Lysimachia,  evidently 
opens  transversely  in  the  specimens  I  have  examined,  though  it  is  sometimes,  from  pressure,  split  at  the  top  also. 
Us  habit  resembles  the  Abyssinian  A.  serpens,  Hochst.

A  highly  variable  plant ;  always,  however,  in  all  the  specimens  which  I  have  examined,  retaining  the  characters 
of  a  short  capside  dehiscing  across  the  middle,  the  broad  lower  half  of  which  is  as  long  as,  or  very  little  longer

(vid.  Flor.  Antarct.  Pt.  1.  p.  65),  and  the  P.  Andicola,  Gill.  MSS.;  the  former  of  these  differs  in  its  shorter  capsule, 
differently  shaped  seeds,  crowded,  more  fleshy  foliage ;  the  latter  in  its  curious  root  and  broader  leaves,  which  are, 
however,  very  unimportant  characters. 

The  Port  Gregory  specimens,  of  which  I  have  made  variety  /3,  are  perhaps  drawn  up,  for  the  leaves  are  six 
inches  long,  which  is  at  least  four  times  the  length  of  those  of  the  ordinary  state  of  the  species.

This  very  distinct  species  has  been  used  as  a  pot-herb  by  the  colonists  of  the  Falkland  Islands,  and  was

contrasted  with  the  jointed  angulated  tube  of  the  perigonium  in  the  Antarctic  American  plant,  which  has  an 
eglandulose  faux  and  plumose  stigma.  The  thickening  of  the  throat  of  the  perianth  in  I).  Dieffeniachii,  which  almost 
causes  the  faux  to  be  closed  with  scales,  is  effected  by  the  three  nerves  of  each  segment  being  there  joined  by 
anastomosing  venules,  whilst  in  D.  muscosa  they  run  free  to  the  apex  of  the  segment.

Not  an  uncommon  species  from  Valparaiso  to  the  Strait  of  Magalhaens,  differing  from  the  preceding  in  its 
robust  habit,  different  texture  of  the  leaves,  and  setose  stem  and  foliage,  all,  I  fear,  very  unimportant  characters 
in  this  genus,  but  whose  validity  in  the  present  species  I  have  not  sufficient  materials  for  ascertaining.  The 
characters  drawn  from  the  length  of  the  racemes  is  a  variable  one,  those  bearing  male  flowers  especially  being  the 
shortest,  and  sometimes,  as  described  by  Poiret,  shorter  than  the  petioles.  The  present  appears  very  closely 
allied  indeed  to  a  South  African  species,  and  it  may  even  be  considered  doubtful  whether  both  are  not  states 
of  U.  dioica,  with  unusually  large  flowers. 

One  of  Anson's  vessels,  when  detached  from  his  squadron,  put  into  a  Bay  near  the  western  entrance  of  the 
Strait  of  Magalhaens,  and  recruited  her  crew,  who  were  paralyzed  by  scurvy,  by  means  of  Nettle  tops,  most  probably 
the  produce  of  this  or  the  former  species. 

The  Urtica  lanrifolia,  Poiret,  stated  to  have  been  brought  from  the  Strait  of  Magalhaens  by  Commerson,  does 
not  appear  to  belong  to  this  genus.  I  am  wholly  unacquainted  with  the  U.  gigantea,  of  the  same  author,  also  from

The  appearance  of  the  so-called  pubescence  of  this  species  and  many  other  Urticea  is  curious,  and  caused  by 
the  presence  of  numerous  white  fusiform  raphides  attenuated  at  both  ends,  which  are  scattered  abundantly  throughout

and  transparency  of  the  leaves  when  dried,  they  form  prominences  on  the  cuticle  of  a  white  colour,  closely  simulating 
the  laterally  attached  hairs  of  Orucifera.

I  am  unable  to  detect  any  characters  to  separate  the  Empetrum  rut/rum  from  E.  nigrum,  beyond  what  is 
afforded  by  the  colour  of  the  berries.  Though  many  of  the  northern  specimens  of  E.  nigrum  are  perfectly  similar 
to  Fuegian  specimens  of  E.  rubrurn  in  every  other  respect,  yet  almost  all  the  Falkland  individuals,  and  many 
of  those  of  Cape  Horn,  are  more  tomentose  than  any  specimens  of  the  Northern  species  that  I  have  examined. 
Under  these  circumstances,  the  plants  from  the  opposite  hemispheres  may  be  regarded  as  representative  species,  or 
varieties  of  the  same ;  but,  since  all  the  specimens  from  the  southern  hemisphere  present  one  constant  character, 
distinguishing  them  from  those  of  the  northern,  and  since  neither  is  known  to  occur  in  any  part  of  the  New  World 
between  the  parallels  of  -15°  N.  and  33°  S.,  I  feel  myself  obliged  to  attach  specific  importance  to  the  otherwise 
very  trifling  differences  in  the  colour  of  the  fruit. 

The  Empetrum  rubrurn.  is  a  very  abundant  western  extra-tropical  South  American  plant,  from  the  latitude  of 
Conception  on  the  Pacific  coast,  and  Mendoza  on  the  Andes,  to  Cape  Horn.  In  the  latter  country,  as  in  the 
Falkland  Islands,  this  species  altogether  simulates  E.  nigrum  in  the  localities  it  affects,  in  its  habit  and  mode  of 
growth,  stature,  in  the  forms  its  varieties  assume,  and  in  the  economy  of  nature,  affording  food  to  wild-geese,  and, 
in  Fuegia,  to  a  bird  allied  to  the  grouse.  The  stems  and  leafy  branches  are  much  used  for  fuel  in  the  Falklands, 
where  the  plant  is  called  "  Diddle-dee  ",  they  are  especially  employed  in  kindling  fire,  for  even  when  sodden  with 
rain,  they  speedily  ignite,  and  burn  with  a  bright  and  hot  fiame. 

The  affinities  of  this  genus,  or  rather  order,  are  yet  undefined.  I  am  inclined  to  adopt  the  opinion  of  Jussieu 
in  allying  it  to  Ericete,  from  the  habit,  foliage,  the  bractere,  calyx,  and  texture  of  the  corolla  and  anthers  and  some 
other  characters.

346  FLORA  ANTARCTICA.  [Fuegia,  the 

friend  Mr.  Darwin,  it  is  advisable  to  sum  up  the  principal  facts  connected  with  their  history,  adding  some  little 
from  personal  observation.  These  remarks  will  be  the  more  appropriately  introduced  here,  from  the  two  principal 
species  having  been  first  imported  into  England  by  the  Antarctic  Expedition,  and  now  promising  to  become  useful 
and  ornamental  additions  to  our  forests;  as,  also,  from  their  geographical  range  having  been  used  as  an  indication 
of  the  limits  of  the  Antarctic  Flora. 

The  Fagus  Antarctica  has  always  been  recognized  as  a  true  Beech,  from  the  very  marked  resemblance  its 
deciduous  foliage  bears  to  that  of  the  European  F.  sylcatica.  The  other  common  Fuegian  species,  F.  betuloides, 
with  coriaceous  leaves  of  a  deep  green  hue  very  similar  to  those  of  the  Scottish  Birch,  was,  up  to  the  discoveiy  of  its 
flowers,  considered  to  be  a  Betula.  The  habit  of  both  species,  however,  is  essentially  that  of  the  Beech,  and  so 
are  the  form  of  trunk,  smooth  bark,  and  especially  the  spreading  ramification  and  horizontal  divaricating  ramuli ; 
whilst  their  flowers  and  fruit  resemble  so  closely  in  all  but  size,  those  of  the  European  Fagus  sylcatica,  that  I  consider 
them  as  undoubted  congeners  of  that  plant. 

I  have  elsewhere  (vid.  ante  p.  277)  alluded  to  the  very  common  error  of  holding  the  locality  in  which  a  certain 
species  particularly  abounds,  to  be  the  principal  habitat  of  the  order  or  genus  to  which  it  belongs  ;  this  often 
arises  from  attaching  a  greater  importance  to  the  spread  of  the  species  than  that  of  the  genus.  Naturalists  unac- 
quainted with  the  range  of  the  Beeches,  will  be  surprised  to  hear  that  they  are  more  characteristic  of  the  temperate 
and  cold  latitudes  of  the  southern,  than  of  the  northern  hemisphere,  even  in  the  proportion  of  five  to  one.  Thus, 
one  species  alone  is  European,  and  one  American  ;  two  are  found  on  the  mountains  of  Java  ;  one  is  characteristic  of 
the  Alps  of  Tasmania,  where  the  only  Antarctic  representatives  of  the  Australian  Flora  are  found ;  four  inhabit  the 
high  mountains  of  the  northern  or  lower  levels  in  the  middle  and  southern  Islands  of  New  Zealand  ;  and,  lastly, 
as  many  as  seven  *  have  been  described  from  Chili  and  Fuegia. 

Of  the  seven  so  called  Chilian  and  Fuegian  species,  three  are  well  marked,  and  afford  instructive  examples  of 
the  succession  of  species  in  proceeding  northward  from  Cape  Horn  ;  they  are  the  F.  Antarctica,  betuloides,  and 
obliqua  ;  the  others,  which  may  be  varieties  of  the  above,  though  from  the  want  of  copious  suites  of  good  specimens 
I  advance  this  opinion  with  much  hesitation,  are  F.  Pumilio,  Poepp.  and  Endl.,  F.procera,  P.  and  E.,  F.Dornbeyi, 
Mil'b.,  and  F.  alpina,  P.  and  E. 

The  Fagus  Antarctica,  justly  so  named,  ascends  even  at  Cape  Horn  much  higher  than  F.  betuloides,  and  nearly 
to  the  summits  of  the  mountains,  which  are  perhaps  1000  feet  below  the  assumed  level  of  perpetual  snow  in  that  lati- 
tude, while  at  the  sea  it  forms  much  the  larger  tree  of  the  two.  Supposing  the  continent  of  America  to  have  been 
produced  indefinitely  to  the  southward,  in  a  free  ocean,  the  F.  Antarctica  would  be  found  extending  to  as  high  a 
parallel  as  62°  S.,  whilst  the  F.  betuloides  would  cease  at  the  60th  degree  :  assuming  that  both  species  followed  the 
same  ratio  of  ascent  that  very  many  other  Cordillera  plants  do,  which  ascend  from  the  level  of  the  sea  in  Fuegia  to 
a  considerable  elevation  in  a  lower  latitude. 

Fagus  betuloides,  though  by  far  the  most  prevalent  species  in  Hermite  Island,  and,  indeed,  throughout  Fuegia, 
has  its  principal  parallel  about  the  Strait  of  Magalhaens,  where  it  becomes  a  very  large  tree.  It  forms  the  prevailing 
feature  in  the  scenery  of  Ticrra  del  Fuego,  especially  in  winter  time,  from  having  persistent,  evergreen  leaves,  and 
from  its  upper  limit  being  sharply  defined  and  contrasting  with  the  dazzling  snow  that  covers  the  matted  but  naked 
branches  of  the  F.  Antarctica,  which  immediately  succeeds  it.  Its  upper  limit  at  Cape  Horn  (lat.  56°)  is  about 
800  feet;  in  the  northern  parts  of  Tierra  del  Fuego  it  reaches  1,400  feet;  and,  if  the  F.  alpina,  P.  and  E.,  be  a 
state  of  the  same  species  in  its  most  northern  locality,  its  level  in  lat.  36°  is  between  5,000  and  8,000  feet. 

The  following  notice  of  the  dimension  the  Evergreen  Beech  attains  in  the  Strait  of  Magalhaens,  is  extracted 
from  Capt.  King's  excellent  '  Voyage  of  the  Adventure  and  Beagle '  (p.  576).   "  At  Port  Famine  and  in  the  neigh- 

*  An  eighth,  F.  glutinosa,  Poepp.,  is  no  Fagus  at  all,  but,  as  my  friend  Mr.  Miers  assures  me  (and  he  has 
examined  authentic  specimens  in  M.  Delesscrt's  Herbarium),  a  species  of  Eucryphia. 


Falkfanck,  etc.]  FLORA  ANTARCTICA.  347 

bourhood,  the  Evergreen  Beech  grows  in  the  greatest  abundance  and  reaches  a  very  large  size.  Trees  of  this  species 
three  feet  in  diameter,  are  abundant;  of  four  feet  there  are  many;  and  there  is  one  tree  (perhaps  the  very  same 
noticed  by  Commodore  Byron),  which  measures  seven  feet  in  diameter  for  seventeen  feet  above  the  roots,  and  then 
divides  into  three  large  branches,  each  of  which  is  three  feet  through.  This  venerable  tree  seemed  to  be  sound,  but  from 
our  experience  of  several  others  that  were  cut  down,  might  be  expected  to  prove  rotten  in  the  centre.  This  tendency 
to  decaying  in  the  heart  may  be  attributed  to  the  coldness  of  the  schistose  sub-soil  upon  which  the  trees  are  rooted, 
as  well  as  the  perpetual  moisture  of  the  climate." 

The  wood  of  these  trees  Capt.  King  describes  as  being  heavy  and  far  too  brittle  for  masts,  or  even  boat-hook 
staves  ;  but  it  cuts  up  into  tolerable  planks,  which,  if  seasoned,  might  serve  for  ship-building.  During  our  sojourn  in 
Hermite  Island,  Capt.  Ross  caused  several  thousand  small  trees,  of  both  species,  to  be  felled  and  barked ;  these 
we  transported  to  the  Falkland  Islands,  in  which  tree-less  country  they  were  highly  prized  for  roofing  houses,  Ste. 
The  deciduous  species  appeared  to  afford  the  better  wood  of  the  two. 

A  more  striking  contrast  between  two  so  very  closely  allied  plants,  cannot  well  be  imagined,  than  between 
F.  Antarctica  and  F.  betuloides,  arising  from  the  evergreen  foliage  of  the  latter  being  of  a  totally  different  texture  and 
aspect  from  that  of  the  former.  Surely  so  strongly  marked  a  difference  between  otherwise  very  nearly  allied 
species,  growing  side  by  side  under  jwrfectly  similar  conditions,  is  a  strong  argument  in  favour  of  their  being 
originally  separate  creations.  We  see,  too,  how  the  adaptation  of  particular  forms  of  vegetation  to  certain  climates, 
even  in  this  remote  quarter  of  the  globe,  is  exemplified  in  these  trees ;  though  both  do  grow  together  abundantly, 
they  still  have  their  preferences,  the  evergreen  glossy  foliage  prevailing  on  the  western  coast,  where  the  climate  is 
damp  and  equable,  whilst  the  deciduous-leaved  plant  seeks  the  heights  more  exposed  to  the  vicissitudes  of  the 
weather,  or  the  drier  eastern  parts  of  Fuegia,  where  the  F.  betuloides  will  not  succeed.  So  it  is  with  us  in  Great 
Britain ;  our  glossy-leaved  evergreens,  whether  native  or  introduced,  thrive  best  in  the  climate  of  the  west  coast, 
where  the  summers  are  colder,  the  winters  wanner,  and  all  the  seasons  more  humid  than  they  are  on  the  east. 

The  third  species  of  Fa/jus,  the  F.  obliqua,  replaces  F.  Antarctica  in  South  Chili,  occupying  the  flanks  of  the 
Andes,  between  the  altitudes  of  1,000  and  5,000  feet,  where  it  is  the  prevailing  forest-tree.  It  appears  to  inhabit 
the  level  of  the  sea  in  the  parallel  of  the  Strait  of  Magalhaens,  and  is  probably  the  third  species  of  Beech  alluded  to 
by  Capt.  King  (1.  c.  p.  576),  for  that  voyager  does  not  seem  to  have  distinguished  the  F.  Pumilio  as  a  species. 

The  accompanying  cut  will  explain  better  than  words,  the  order  of  succession  in  latitude  and  in  elevation  that 
South  American  Fagi  follow.  Their  southern  ranges  may  be  ascertained  with  tolerable  precision,  the  exact  altitude 
they  attain  in  the  two  northern  positions  is  more  doubtful.  The  positions  taken  are,  commencing  from  the  southward, 
1st,  Hermite  Island,  lat,  56°;  2nd,  Strait  of  Magalhaens,  hit.  54°;  3rd,  Antuco  in  Chili,  hit.  36°  40'.  The  upper 
curve  indicates  the  lower  level  of  perpetual  snow  ;  the  others,  the  upper  limit  of  the  tree  whose  name  is  found 
immediately  under. 

From  the  want  of  a  suite  of  specimens  I  cannot  speak  with  much  confidence  of  the  Chilian  species,  F.  alpina 
and  F.  Pumilio,  the  first  appears,  from  the  plate  and  description,  a  variety  of  F.  betuloides,  and,  from  occupying  the 
position  that  F.  betuloides  would  hold  relatively  to  the  others  in  South  Chili,  I  have  introduced  it  as  such  into  the  cut. 
The  F.  Pumilio  is  even  more  probably  a  variety  of  F.  Antarctica.  Both  are  said  to  occupy  great  heights  in  South 
Chili,  the  latter  indeed  only  existing  there  as  a  stunted  tree.  There  are  still  two  other  South  Chilian  species, 
F.  procera,  P.  and  E.,  and  F.  Dombeyi*  Mirb. ;  they  inhabit  the  level  of  the  sea  in  the  parallel  of  41°.  The 
first  I  am  inclined  to  regard  as  a  variety  of  F.  obi i qua,  or  rather  a  large-leaved  state  of  that  plant  descending  to  the 
coast ;  the  second  is  a  similar  form  of  F.  betuloides.      If  my  supposition  prove  correct,  both  species  afford  examples 

*  This  is  one  kind  of  "  Roble  "  of  Capt.  King's  Narrative  (p.  280)  ;  in  speaking  of  the  woods  of  Chiloe,  he 
says,  "  Roble,  {Fayus  obliqua,  Mirb.),  is  a  large  tree,  and,  from  the  durable  quality  of  its  timber,  considered  the

F.  obliqua.  The  abrupt  termination  of  all  the  Beeches  at  about  lat.  35°,  occurs  where  the  equally  sudden  change  in 
the  climate  of  northern  and  southern  Chili  takes  place.  These  trees,  like  all  extra-tropical  plants,  require  a  certain 
degree  of  cold,  and  in  pursuing  their  range  towards  the  warmer  parallels,  they  ascend  the  mountains.  They  are, 
however,  even  more  dependent  upon  humidity  and  an  equable  climate  than  on  temperature ;  and  being  further 
impatient  of  vicissitudes  and  dryness,  they  will  not  pass  beyond  the  influence  of  those  S.W.  winds  which  drench 
all  parts  of  western  South  America,  alpine  and  lowland,  south  of  the  parallel  of  37°.

One  of  the  few  attractions  of  spring  in  Antarctic  America,  is  the  bursting  of  the  leaf  and  flower  buds  of  <h 
deciduous-leaved  Beech  from  their  resinous  gummy  scales  ;  when  a  delightfully  fragrant  odour  pervades  the  woods. 
The  unfolding  of  the  plaited  foliage  was  watched  with  great  interest,  for  we  bad  not  witnessed  for  years  any  process 
so  closely  resembling  that  of  an  English  spring.  It  recalled  Linnaeus'  enthusiastic  description  of  the  first  burst 
of  the  birch  leaf  in  Lapland. 


best  in  the  island,  for  ground-frames  of  houses,  planks  for  vessels,  and  beams.     The  piraguas  are  built  chiefly  of 
this  wood.     There  are  two  sorts,  one  an  evergreen,  and  the  other  a  deciduous-leaved  tree.     It  is  evidently  a  Beech, 
aud  the  same  that  grows  in  all  parts  of  the  Strait  of  Magalhaens ;  the  smooth-leaved  sort  is  F.  obliqua,    I    I 
Capt.  King  attaches  the  name  of  "  Roble  "  to  his  specimen  of  F.  Dombeyi.

This  I  take  to  be  the  third  kind  of  Beech  alluded  to  by  Capt.  King  as  a  native  of  Port  Famine,  in  his 
collections,  however,  no  specimen  of  the  present  species  occurs.  It  is  distinguishable  from  the  former  chiefly 
by  the  larger,  narrower,  rhomboidal,  more  acute  leaves.

I  have  alluded  to  this  Beech  (under  F.  Antarctica)  as  perhaps  only  a  state  of  that  plant,  differing  in  the  leaves 
being  pubescent  on  both  surfaces  and  more  closely  and  deeply  serrated.  The  figure  of  Poeppig  and  Endlicher  is 
excellent ;  that  of  MM.  Hombron  and  Jaequinot,  in  the  '  Voy.  au  Pole  Sud ',  represents  a  narrower  and  smaller- 
leaved,  perhaps,  alpine  state ;  or  more  probably  a  different  species,  those  authors  having  included  it  in  their  not 
yet  described  genus  Calusparassus.  Judging  from  their  figures  of  other  Antarctic  Fagi,  also  called  Calusparassi, 
the  genus  appears  to  include  only  those  evergreen  species  of  which  the  leaves  are  not  phcate  in  vernation, 
which  those  of  the  F.  Pumilio  decidedly  are,  both  in  our  specimens  and  those  described  and  figured  by  Poeppig. 

The  latter  author  states  this  to  be  a  short  prostrate  tree,  eight  and  twelve  feet  long,  with  a  mode  of  growth 
not  unlike  that  of  Pinus  Pumilio.  It  marks  (in  Chili)  the  transition  zone,  from  the  erect  trees,  whose  superior 
limit  is  indicated  by  the  F.  alpina,  to  the  frigid  region,  where  snow  hes  for  eight  months  of  the  year,  and  where 
the  shrubby  Composite,  and  the  Violets  that  grow  in  dense  capitate  tufts,  and  other  handsome  plants,  abound. 

I  have  marked  the  habitat  assigned  to  Capt.  King's  specimen  with  a  query,  the  label  attached  to  it  bearing 
"  Cape  Fairweather  ",  where  it  is  exceedingly  improbable  that  any  Fagus  should  exist.

Hab.  South  Chili  and  Strait  of  Magalliaens ;  Port  Famine,  Ca_pt.  King. 

This  species  has  been  described,  on  the  authority  of  Mr.  Bridges,  as  the  true  "  Alerse  "  of  Chili.  Upon  showing 
my  specimens,  however,  to  M.  Claude  Gay,  the  celebrated  Chilian  traveller,  he  assured  me  that  the  "  Alerse  "  was 
a  totally  different  plant,  and  not  a  Thuja  at  all ;  a  statement  the  more  probable,  from  Capt.  King's  description  of 
the  Alerse  leaves,  which,  he  says,  resemble  those  of  a  Pine  in  colour,  but  are  ouly  half  an  inch  long ;  though  the 
difference  may  arise  from  the  young  and  old  states  of  this,  as  of  other  Conifera,  often  bearing  leaves  of  a  very  different 
appearance.  When  enumerating  the  woods  in  use  in  the  Island  of  Chiloe,  Capt.  King  mentions  in  one  place  (p.  281) 
the  "  Alerse  "  and  "  Cypress  ",  which  are  thus  usually  considered  as  different  plants,  and  says  that  the  "  Cypress  "  is 
brought  to  that  Island  in  "  tablones  "  (or  planks),  seven  or  eight  feet  long,  two  inches  thick,  and  nine  or  twelve 
inches  wide,  as  is  also  the  "Alerse";  but  the  latter,  from  the  facility  in  which  it  splits,  is  brought  in  boards  also. 
The  same  voyager  observes  (p.  183)  that,  though  the  "  Cypress  "  is  thought  to  be  a  different  tree  from  the  "  Alerse  " 
he  considers  it  only  a  variety,  the  wood  being  white,  whilst  that  of  the  "  Alerse  "  is  deep  red.  Naturalists  who 
are  aware  how  uncertain  are  the  limits  of  the  acknowledged  species  and  varieties  of  European  Conifera,  will  readily 
appreciate  the  difficulty  that  attends  the  determination  of  those  of  an  opposite  hemisphere,  oidy  known  to  us  through 
insufficient  specimens,  vague  reports,  and  incorrect  infomiation.  Capt.  King  evidently  believes  the  "  Cypress  " 
and  "  Alerse  "  to  be  identical,  for  he  affirms  that  the  former  grows  commonly  in  the  Strait  of  Magalhaens,  in 
all  parts  west  of  Cape  Forward,  but  that  there,  from  the  poverty  of  the  soil,  the  wood  is  of  very  stunted  growth 
(p.  283)  ;  and  this  description  tallies  with  the  specimens  of  Thuja  tetragona  in  his  Herbarium. 

Thuja  tetragona  is  apparently  a  rare  Magellanic  plant.  Capt.  King  says  it  is  found  on  the  north  shore 
of  the  Strait  between  Cape  Forward  and  Port  Gallant,  but  not  to  the  eastward,  except  on  the  sides  of  Mount  Tarn, 
where  it  only  reaches  the  height  of  three  or  four  feet  (King's  Voy.  p.  131).  The  same  author  elsewhere  states 
that  the  natives  make  their  spears  of  its  wood  (p.  568).  In  Hermite  Island  where  the  Thuja  does  not  exist 
Drimys  Winteri  is  used  for  that  purpose.

its  leaves.  It  differs  from  the  ft  alpina,  Toepp.,  of  South  Chili,  by  the  flowers  being  very  much  smaller,  and 
the  sepals,  petals,  and  labellum  differently  formed.  Both  the  figure  and  description  of  Brongniart,  are  very 
good.

Brongniart's  description  and  figure  are  very  characteristic  of  the  Falkland  Island  specimens  of  this  plant, 
which  is  quite  distinct  from  the  following.  I  have  seen  no  Magellanic  or  Fuegian  individuals,  Cajrt.  King's  Port 
Famine  Chlorcea  or  Asarca  being  a  totally  different  species.  Mi-.  Wright  and  Mr.  Chartres  having  gathered  it  in 
the  Western  of  the  two  Falkland  Islands,  and  no  other  collectors  having  met  with  it  in  the  Eastern,  I  am  inclined 
to  consider  this  plant  as  one  of  the  Fuegian  species  which  has  not  spread  to  the  eastern  parts  of  the  group,  as  is 
the  case  with  the  Veronica  elliptica.

The  short  column  has  induced  me  to  refer  this  very  distinct  plant  to  the  genus  Asarca,  for  in  a  dried  state  it 
is  almost  impossible  to  determine  whether  the  petals  are  patent  or  conniving.

A  species  which  has  been  erroneously  included  by  Sprengel  in  the  terete  stemmed  group,  and  even  considered 
by  Lindley  and  Dietrich  to  be  synonymous  with  S.  iridifolium,  Kunlh,  (Marica  iridifolia,  Bot.  Eeg.  t.  646).  Such 
may  be  the  case,  but  I  have  seen  no  specimens  decidedly  connecting  these  two  species,  and  therefore  hesitate 
before  adopting  a  conclusion  which  would  give  this  plant  a  geographical  range  from  the  equator  to  the  Strait  of 
Magalhaens.  Still,  the  var.  major  is  so  decidedly  scabendous,  so  much  larger,  and  so  much  more  resembling 
the  S.  iridifolium  than  the  var.  minor,  that  there  is  nothing  improbable  in  the  supposition  that  both  are  varieties  of 
one  tropical  species.     S.  laxum  is  also  a  native  of  Valparaiso.

giving  off  at  its  apex  a  terete  scape  and  short  leafy  stem.  Leaves  about  three,  with  scariose  sheaths  at  the  base, 
filiform,  terete,  six  or  seven  inches  long.  Scape  shorter  than  the  leaves,  furnished  at  the  middle  with  two  leaf-like 
opposite  bractese  sheathing  at  the  base.  Peduncle  solitary,  one-flowered,  shorter  than  the  bracteas,  erect.  Fruit 
immature,  globose,  trigonous  (?),  the  size  of  a  small  pea,  three-locular  (?),  each  cell  containing  several  seeds  on 
parietal  (?)  placenta?. 

The  above  diagnosis  may  serve  to  distinguish  this  curious  plant,  which  differs  chiefly  from  Sisyrincliium  in  the 
scape  not  springing  from  between  the  uppermost  leaves,  but  from  the  base  of  the  outer  one,  and  in  there  being 
no  spatha  to  any  of  the  specimens  ;  though  the  scape  in  one  instance  bears  the  scar  of  a  fallen  leaf,  half-way 
between  the  insertion  of  the  bracteae  and  the  rhizoma.

I  quite  agree  with  Mr.  Miers  in  removing  this  plant  from  Sisyrincliium.  Thunberg's  habitat  of  the  Strait  of 
Magalhaens,  from  whence  he  originally  described  this  plant  as  Gladiolus  biftorus,  has  been  replaced  by  that  of  the 
Cape  in  most  succeeding  authors,  except  Yahl  (En.  Plant,  vol.  ii.  p.  97),  and  Willdenow  (Sp.  PL  vol.  i.  p.  209).

The  accompanying  plate  and  analysis  of  this  curious  little  plant  represent  ah  its  characters,  and  especially 
those  which  have  induced  me  to  retain  the  genus  which  the  illustrious  Jussieu  formed,  but  which  has  not  been 
adopted  by  any  succeeding  author.  It  is  to  be  distinguished  from  Sisyrinchium  by  its  very  remarkable  habit, 
coriaceous  perianth,  and,  more  especially,  by  the  capsule  dehiscing  at  the  apex,  and  the  ovules  and  seeds  occupying 
only  the  lower  hah  of  each  placentiferous  dissepiment.  To  the  southward  of  the  Strait  of  Magalhaens,  where 
SisyrincMa  do  not  extend,  this  little  plant  represents  that  genus,  and  is  also  the  analogue  of  the  Libert'ue  of  New 
Zealand. 

The  curious  and  beautiful  distichous  arrangement  of  the  foliage,  is  characteristic  of  this  and  of  some  other 
especially  alpine  Antarctic  plants,  belonging  to  several  natural  orders,  amongst  the  majority  of  the  species  of  which 
such  a  foliation  is  foreign  or  very  rare.  Thus,  in  Cyperacea  it  is  seen  in  Oreobolus  pectinatm  (pt.  1.  t.  49);  amongst 
Rest iacea,  in  Gaimardia pallida  (p.  86);  amongst  Alwnacea,  in  Tetroncium  Hagellanicum  (t.  128);  and  amongst 
Juncea,  in  the  Peruvian  Distichya  muscoides,  Nees  and  Meyen  (Nov.  Act.  Acad.  Caes.  vol.  xix.  Suppl.  p.  77),  which  is 
probably  the  Goudotia  Tolimensis,  Decaisne  (Arm.  Sc.  Nat.  ser.  3.  vol.  iv.  p.  83.  t.  4).  This  tendency  to  assume  a 
certain  habit,  which  these  otherwise  wholly  dissimilar  plants  present,  is  perfectly  analogous  to  what  occurs  even  more 
conspicuously  in  the  vegetation  of  the  Cape  of  Good  Hope  and  Australia ;  and  one  of  the  most  singular  phenomena 
of  the  vegetable  kingdom.

A  very  elegant  little  plant,  remarkable,  especially  in  the  Falkland  Islands,  for  its  very  sweet-scented  flowers. 

The  extrorse  anthers  of  this  genus  have  been  hitherto  overlooked,  from  the  versatde  nature  of  then  attachment. 
The  embryo,  described  as  amphitropal,  at  first  is  nearly  atropal ;  but  apparently  during  the  maturation  of  the 
ovarium  the  seed  becomes  partially  inverted,  so  as  to  be  placed  at  right  angles  with  the  funiculus,  and  the  embryo 
is  consequently  heterotropal. 

Callixene  is  an  Antarctic-American,  and  New  Zealand  genus.  From  the  latter  country  Mi'.  Colenso  has  sent 
the  C.parvifiora,  Hook.  fil.  (Hook.  Ic.  Plant,  t.  632),  which  grows  at  the  foot  of  large  Beech  trees,  lying  prostrate

against  their  trunks  in  the  mountain  forests,  as  the  C.  margiuata  does  at  Cape  Horn.  Their  Australian  representative 
is  the  Brymophila  cyaiwcarpa,  Br.,  a  subalpine  Tasmanian  plant,  very  similar  to  them  in  habit.

Except  by  the  parietal  placentation,  the  genera  Philesia  and  Lapageria  (themselves  very  closely  allied),  differ  in 
no  important  points  from  Callixene  and  Luzuriaga,  and  since  placentation  does  not  afford  characters  of  the  impor- 
tance amongst  Monocotyledonous  that  it  does  in  Dicotyledonous  Orders,  I  see  no  objection  whatever  to  arranging 
these  two  genera  under  Smilacea  proper  and  next  to  Callixene. 

In  Asteliacea,  as  I  have  mentioned  elsewhere,  the  placenta;  are  axile,  parietal  or  pendulous  ;  in  Juncete,  parietal 
or  basal ;  in  Amaryllidea,  axile  or  parietal ;  in  Liliacea,  the  same ;  and  other  orders  equally  display  a  very  con- 
siderable amount  of  variation  in  the  consolidation  of  the  carpels,  and  consequent  disposition  of  the  placenta?, 
unaccompanied,  however,  with  any  other  characters  of  more  than  generic  value. 

In  all  other  respects,  Philesia  is  even  generically  very  nearly  related  indeed  to  Callixene,  through  Luzuriaga,  which 
has  the  three  inner  segments  of  the  perianth  still  larger  in  proportion  than  in  Callixene ;  and  on  the  other  hand, 
through  Lapageria,  in  which  they  are  all  equal  in  size.  The  habit,  texture,  distichous  insertion  of  the  leaves,  which 
are  all  on  the  same  plane  with  the  ramuli ;  the  texture,  nervation,  margination,  and  even  fonn  of  the  leaves,  which 
are  glaucous  beneath,  are  alike  in  Callixene  and  Philesia ;  so  are  the  terminal,  large,  solitary,  bracteate  flowers,  the 
texture  of  the  perianth,  extrorse  anthers,  baccate  fruit,  the  numerous  ovules  in  two  series  on  three  rows  of  placenta?, 
the  many  ovoid  seeds,  delicate  testa,  dense  albumen,  and  axile  embryo  which  is  of  similar  form  in  the  two.  The 
only  difference  in  the  ovules  is,  that  those  of  the  Callixene  are  heterotropal,  those  of  Philesia  nearly  straight  or 
atropal,  characters  rather  indicating  close  affinity  than  the  contrary. 

With  regard  to  the  genus  Lapageria,  R.  and  P.,  it  is  so  closely  allied  to  Philesia  that  I  doubt  its  validity,  the 
chief  differences  being  the  nearly  equally  divided  perianth  of  Lapageria,  its  more  distinctly  three-lobed  stigma,  oblong 


356  FLOKA    ANTARCTICA.  [Fuegia,  the 

berry,  twining  branches,  and  differently  nerved  leaves,  in  all  which  respects  it  is  more  evidently  a  genus  of 
Smilacetz,  than  either  Callixene  or  Pkilesia.  There  is  no  reason  for  supposing  Doinbey's  Capia  to  be  other  than 
Lapageria  rosea. 

It  appears  to  me  to  be  through  these  Antarctic  and  extra-tropical  American  genera,  together  with  the  Callixene 
of  New  Zealand  and  Drymophila  of  Tasmania,  that  the  Smilacea,  Lindl.,  are  inseparably  connected  with  the  Tribe 
Asparagea,  Lindl.,  of  LUiacece ;  groups  which  Dr.  Lindley  has  placed  in  separate  natural  classes,  on  the  ground 
chiefly  of  anatomical  differences  in  their  stems :  and  it  further  appears  that  all  modifications  of  a  stem  typical  of 
Endogens  and  one  equally  characteristic  of  Dictyogens  may  be  traced  amongst  these  plants. 

My  own  observations  on  the  wood  of  P/tilesia  do  not  exactly  lead  to  the  conclusions  that  the  learned  author  of 
the  '  Vegetable  Kingdom '  has  formed ;  what  appears  to  be  bark  is  at  no  period  separable  from  the  subjacent  wood, 
and  the  pith  is  of  undefined  form.  There  is  a  resemblance  between  the  bark  of  Pkilesia  and  that  of  an  exogenous 
stem,  but  it  is  apparent  and  not  real :  the  stem  consists  of  one  mass  of  cellular  tissue,  through  which  bundles  of 
vascular  tissue  descend,  between  the  axis  and  the  cuticle ;  abundantly  towards  the  latter,  where  they  all  coalesce, 
though  always  at  a  little  distance  within  the  circumference ;  more  sparingly  towards  the  axis,  where  a  space  is  often  left 
wholly  unoccupied  with  woody  fibres.  A  transverse  section  of  such  a  stem  thus  presents,  1st,  a  cuticle;  2nd,  a  zone 
of  cellular  tissue,  often  formed  of  thick  walled  cells  ;  3rd,  a  zone  of  wood,  dense  and  defined  externally,  gradually 
laxer  towards  the  axis  and  separating  into  bundles  which  irregularly  surround  a  central  column  of  pith.  The  only 
difference,  in  short,  between  this  and  any  other  Endogenous  stem,  consists  in  the  first-formed  or  outer  bundles  being 
disposed  more  symmetrically,  and  being  combined  into  one  zone. 

If  a  branch  of  Luzuriaga  radicans  be  examined,  the  same  peculiarity  will  be  perceived,  with  only  this  difference, 
that  the  zone  of  wood  is  narrower  and  the  pith  broader.  In  Callixene  pohjphylla,  the  woody  zone,  though  still 
continuous,  is  narrower  still.  In  C.  parviflora  both  its  edges  (both  inner  and  outer  circumference)  are  clearly 
defined  ;  and  in  C.  marginata  it  is  sometimes  interrupted. 

The  Callixene  marginata  thus  shows  this  disposition  of  the  outer  vascular  bundles  to  unite  in  the  lowest  degree 
of  these  South  American  Smilacece,  but  in  Lapageria  the  same  tendency  will  be  found  in  its  highest,  for  the  stem  f 
that  plant  is  almost  wholly  composed  of  woody  matter,  concentrated  externally  into  a  well-defined  zone,  rather  lootc-i 
towards  the  centre,  and  enclosing  large  trachea;  with  very  little  cellular  tissue  intermixed.  Externally  to  the  wood 
is  a  very  narrow  layer  of  condensed  parenchyma.  In  the  first  year's  twig  of  this  plant,  the  cellular  tissue  is  pro- 
portionably  abundant,  with  separate  vascular  bundles  scattered  through  it,  but  is  absorbed  or  obliterated  afterwards. 
Nor  is  it  in  the  genera  of  South  America  alone  that  these  woody  bundles  are  thus  arranged,  it  is  so  in  the  Geitono- 
plesium  {Luzuriaga  cymosa,  Br.)  of  New  Holland,  and  in  Drymophila,  Br. ;  and  even  nearer  home  in  Convallaria 
and  probably  in  many  Convallariea.  To  the  last  mentioned  group  the  above  named  genera  most  assuredly  belong  j 
whether  the  venation  be  parallel  as  in  Callixene,  parallel  and  retose  between  the  costae  as  in  Lapageria,  or  wholly 
retose  as  that  of  Pkilesia  appears  to  be,  from  the  two  lateral  of  the  three  parallel  costse  forming  the  thickened 
margin  of  the  leaf. 

On  the  other  hand,  if  we  turn  to  the  Smilacea  proper,  as  limited  by  Dr.  Lindley,  even  they  display  no  more 
deviation  from  the  common  Endogenous  structure  than  do  the  Convallariea:  A  young  shoot  of  Rkipogonmn  shows 
the  same  disposition  of  the  woody  and  cellular  tissue  as  Callixene  polypkylla,  with  rather  a  broader  zone  of  cellular 
tissue  surrounding  the  wood ;  but  in  an  older  stem  of  the  same,  the  wood  so  predominates  over  the  parenchyma, 
that  the  zone  of  cellular  tissue  is  only  distinguished  with  difficulty.  In  the  Sniilax  excelsa,  L.,  of  Em-ope,  the 
woody  zone  of  the  young  branch  is  neither  so  continuous  nor  regular,  but  it  becomes  so  in  the  older  state  of  the 
plant.  Tamus  communis  presents  the  same  arrangement.  In  the  young  stem  of  Testitdinaria.  elepkantipes  I  do  not 
find  the  medullary  plates  described  by  Dr.  Lindley ;  there  appears  to  me  to  be  a  broad  and  perfectly  continuous 
zone  of  wood,  sending  six  or  eight  prolongations  towards  the  axis,  where  there  are  further  a  few  irregularly  disposed 
bundles.     I  shall  conclude  this  long  digression  by  instancing  the  genus  Jnncus  as  of  the  furthest  removed  from 


Fafklands,  etc.]  FLORA  ANTARCTICA.  357 

Dictyogens  in  every  point  of  view,  except  that  it  possesses  an  equally  continuous  and  denned  zone  of  woody  tissue, 
within  the  cuticle,  separated  from  the  latter  by  a  zone  of  parenchyma,  and  enclosing  a  mass  of  pure  pith. 

The  Philesia  buxifolia  is  among  the  handsomest  plants  of  the  Antarctic  American  Flora ;  it  occurs  along  the 
coast  from  the  Strait  of  Magalhaens  to  Yaldivia  ;  to  the  northward  of  which,  between  Valdivia  and  Concepciou,  it 
is  replaced  by  the  Lapageria  rosea.

Under  the  description  of  A.  linearis,  in  the  first  part  of  this  volume,  I  mentioned  that  the  placentation  varies 
in  the  different  species  of  this  genus.  In  the  majority,  the  ovules  are  numerous  and  arranged  in  two  lines  upon 
parietal  placenta? ;  in  one  the  seeds  are  numerous  and  pendent  from  the  summit  of  a  one-celled  berry,  whose  dis- 
sepiments have  probably  been  absorbed  ;  a  third  form  presents  a  three-celled  ovarium,  with  several  ovules  pendulous 
from  the  summit  of  each  cell ;  a  fourth  has  a  three-  to  six-celled  subcapsular  fruit,  with  a  few  pendulous  seeds  in 
each  cell ;  while  the  present  plant  offers  a  fifth  modification,  for  its  placentation  is  decidedly  axile,  and  the  ovules  are 
arranged  in  two  rows  along  the  inner  angle  of  each  of  the  three  cells.  This  arises  from  the  perfect  consolidation 
of  the  carpels  in  a  young  state,  when  the  edges  of  each  carpellary  leaf  are  so  inflected  as  to  meet  in  the  axis  of  the 
pistil,  where  a  triangular  longitudinal  cavity  is  often  left  (see  fig.  5  of  Plate  CXXVII.).  At  an  early  period  the 
cavity  of  each  capsule  is  not  apparent,  the  ovules  being  imbedded  in  a  cellular  mass,  which  in  this  species  retires 
from  between  and  around  the  ripening  seeds,  leaving  a  distinct  cavity  as  the  fruit  advances  to  maturity,  but  in 
some  others  remains,  partly  attached  to  the  placenta?  and  seeds,  as  a  mucilaginous  or  gummy  mass.  At  no  time  is 
the  fruit  of  this  plant  truly  even  sub-capsular,  its  walls  are  always  fleshy,  and  no  trace  of  dehiscence  can  be  seen 
along  the  furrows  of  each  carpel,  from  which  the  seeds  escape  by  the  decay  of  the  pericarp. 

I  have  followed  M.  Brongniart  in  placing  this  genus  by  itself  in  a  natural  group,  whose  nearest  affinities  I 
have  indicated  in  the  first  part  of  this  work. 

The  Astelia  piimila  is  a  most  abundant  Fuegian  and  Falkland  Island  plant,  forming,  with  the  Caltha  appen- 
diculata  especially,  a  large  proportion  of  the  peat  in  those  countries.  Its  flowers  are  inconspicuous,  and  have  a 
faintly  sweet  smell.

The  miserable  natives  of  Fuegia  weave  the  steins  of  this  rush  into  baskets,  and  in  doing  so  seem  to  exhaust 
their  cunning,  for  such  baskets  appeared  to  us  to  be  the  only  article  they  possessed,  exhibiting  any  attempt  at 
such  handy-craft  as  demands  the  slightest  ingenuity,  except,  perhaps,  the  moveable  heads  of  their  sealing  spears.

I  am  not  aware  of  this  species  having  been  gathered  in  Fuegia  since  Commerson's  time,  except  by  myself;  and 
though  abundant  in  Hermite  Island,  it  is  probably  scarce  and  alpine  to  the  north  of  that  locality,  as  it  is  also  in 
Campbell's  Island.

The  present  species,  like  the  former,  can  scarcely  be  considered  truly  Antarctic,  merely  entering  the  northern 
limits  which  I  have  assigned  to  the  Fuegian  Flora.  It  ranges  on  the  coast  from  Valparaiso  to  the  latitude  of  Chonos 
Archipelago  and  is  also  found  on  the  Cordillera  of  Peru. 

Meyer  (Hook.  Herb.)  remarks  that  this  hardly  belongs  to  the  genus  Cephaloxys,  on  account  of  the  structure  of 
its  capsule.

I  have  seen  but  an  imperfect  specimen  of  the  L.  Peruviana,  Desv.,  to  which  the  present  is  manifestly  very 
closely  related.  E.  Meyer  (Herb.  Hook.)  observes,  that  though  so  much  alike  in  the  young  state,  when  older  they 
are  very  distinct  species.  The  present  is  the  most  Antarctic  of  the  genus,  except  the  following,  and  is  the  South 
American  representative  of  the  L.  crinita  (Tab.  XLVIII.)  of  Lord  Auckland's  group.

My  specimens  are  only  sufficient  to  prove  this  plant  to  be  a  Luzula  ;  they  are  scarcely  two  inches  high,  with  a 
slender  stem,  and  nodding  small  panicle  ;  the  whole  somewhat  resembling  the  L.  arcuata  of  Arctic  Europe,  whose 
Antarctic  representative  it  probably  is.

The  arrangement  of  all  parts  of  the  flower  are  quaternary  in  the  specimens  of  this  curious  plant  that  I  have 
examined ;  in  which  respect  it  differs  from  the  majority  of,  and  in  the  albuminous  seeds  from  all  the  order,  Alis- 
macea ;  without,  however,  shewing  any  further  affinity  with  the  Naiadacea,  in  which  order  Dr.  Lindley  has  placed  it. 

The  habit  of  Tetroncium  is  precisely  that  of  Narthecium,  but  in  most  other  points  its  alliance  to  Triglochin 
is  evident,  particularly  in  the  spicate  inflorescence,  concave  segments  of  the  perianth,  which  are  obliquely  placed, 
the  upper  being  larger  and  inserted  above  the  rest ;  in  the  extrorse,  nearly  sessile  anthers ;  the  solitary,  basal, 
anatropal  ovules ;  and  the  erect  seed,  which,  being  albuminous,  indicates  an  affinity  with  Junceee.

Probably  a  very  widely  diffused,  and  certainly  in  size  a  variable  plant,  common  to  both  coasts  of  extra-tropical 
South  America,  and  to  the  Cape  of  Good  Hope.  To  this  may  also  belong  the  T.  Chilen&e,  of  Meyer,  of  which  a 
wholly  insufficient  character  is  given  in  a  foot-note  to  that  traveller's  journey  (Reise  un  die  Erde.  vol.  i.  p.  354). 
Its  nearest  ally  is  the  T.  decipiens,  Br.,  of  Australia,  of  which  T.filifolium.,  Sieb.  (inaccurately  described  as  wanting 
the  abortive  carpels),  is  a  synonym ;  indeed,  the  Australian  differs  from  the  South  American  plant  only  in  the  larger 
fruit,  so  far  as  my  only  specimen  enables  me  to  judge.

It  is  difficult  to  suppose  that  a  plant,  so  abundant  in  the  Falkland  Islands,  should  be  rare  on  the  mountains  of 
the  adjacent  continent,  where,  however,  it  has  only  been  gathered  near  Cape  Horn,  unless  a  species  collected  by 
M.  Goudot  full  4,000  miles  further  north,  on  the  peak  of  Tolima  in  Colombia,  should  prove  to  be  the  same  plant, 
as,  judging  from  a  barren  specimen,  it  very  likely  may.

The  variations  in  the  size,  form,  and  markings  on  the  surface  of  the  achaenia  of  the  otherwise  almost  identical 
forms  of  Isolepis  seem  really  endless.  Falkland  Island  specimens  are  short,  with  small  spikes,  and  small  fuscous 
achaenia,  which  are  broader  than  long  and  punctulate,  but  the  puneta  not  in  parallel  lines.  Mr.  Darwin's  plant  is 
much  longer,  and  has  rather  longer  spikes,  with  elliptical  ovate  larger  achaenia,  which  are  longer  than  broad  and 
similarly  punctulate,  its  culms  are  often  ten  inches  long.  The  /.  lepida,  Nees  (in  Linnaea,  vol.  iv.  p.  291),  judging 
by  Cuming's  Valparaiso  specimens  (in  Herb.  Hook.),  resembles  the  plant  of  Mr.  Darwin,  its  achaenia  are  precisely 
similar  to  those  of  the  Falkland  Island  variety  in  form,  colour  and  surface,  but  scarcely  half  as  large. 

The  Cape  of  Good  Hope  I. pygmcea,  so  called  by  Kunth,  has  the  achsnium  of  /.  lepida,  but  pale  coloured  and 
smaller  still ;  while  the  Auckland  Island  I.  Aucklandica  (p.  88.  t.  L)  has  larger  fruit  than  any. 

All  of  the  above  differ  from  the  European  /.  Savii,  Seb.  and  Maur.,  in  the  achaenia  not  being  so  deeply  punctate 
or  striate.     In  size  and  form  the  pericarp  of  /.  Savii  resembles  that  of  the  Falkland  Island  plant.

north,  in  Australia,  by  the  C.  deusta,  Br.,  a  native  of  the  colony  of  Port  Jackson,  but  hitherto  no  South  American 
species  except  the  one  here  described  has  been  noticed.  These  three  form  together  a  very  distinct  group,  as

Dr.  Boott  has  kindly  favoured  me  with  the  range  of  this  species,  which  is  so  wide  in  the  northern  hemisphere 
that  we  should  quite  expect  that  it  will  hereafter  be  found  along  the  chain  of  the  Cordillera.  Commencing  in 
Greenland  on  the  east,  it  crosses  to  Unalaschka  on  the  west  by  Cumberland  House  on  Bear  Lake,  and  thence  runs 
south  along  the  Rocky  Mountains.     In  Europe  it  has  hitherto  been  found  in  Lapland  only.

The  present,  Dr.  Boott  remarks,  is  decidedly  the  European  C.  curta,  one  Falkland  Island  specimen  alone,  out 
of  very  many,  differing  from  the  others  in  having  ten  spicuke,  the  average  number  being  six  to  eight. 

The  geographical  distribution  of  this  species  is  very  wide,  for  it  inhabits  all  Europe  from  the  latitude  of 
Lapland,  where,  according  to  Wahlenberg,  it  is  excessively  common,  to  the  Mediterranean  region,  which  it  does 
not  enter.     In  Arctic  America  again  it  is  abundant,  extending  in  the.  United  States  as  far  south  as  New  York.

Hab.  Cape  Tres  Montes,  C.  Darwin,  Esq. ;    Falkland  Islands,  abundant,  I)'  Urville,   Capt.  Sutivan, 

j.  n.  h. 

A  very  noble  species,  abundant  in  the  Falkland  Islands,  growing  with,  and  emulating  in  size,  young  Tussock 
grass.  Mr.  Darwin  alone  has  gathered  it  on  the  American  continent,  and  he  only  at  Cape  Tres  Montes.  Its 
confined  range  is  very  singular,  for  it  can  scarcely  have  been  overlooked  in  Fuegia  or  the  Strait  of  Magalhaens,  had 
it  existed  there ;  and  it  is  also  probably  the  only  plant  common  to  New  Zealand  and  the  Falkland  Islands,  not  found 
abundantly  in  Tierra  del  Fuego. 

Carex  trifida  affords  a  remarkable  instance  of  apparent  caprice  in  its  choice  of  habitat ;  for  though  common 
in  the  Falklands,  along  with  the  Bacti/Us  caspitosa  (Tussock  grass),  and  though  there  these  grow  in  company, 
and  under  precisely  the  same  conditions,  yet  the  Tussock  grass  in  America  only  appears  in  the  southern  extreme 
of  Fuegia,  where  it  is  unaccompanied  by  Carex  trifida ;  whilst  the  latter  is  confined  to  a  latitude  eight  hundred 
miles  north  of  Cape  Horn.  There  is  nothing  whatever  in  the  climate  or  soil  of  any  part  of  western  South  Chili, 
or  Fuegia,  that  can  be  pronounced  unfavoiuable  to  the  growth  of  this  Carex,  whose  absence  there  naturaUy 
leads  to  the  question,  how  is  its  presence  in  Cape  Tres  Montes  and  the  Falkland  Islands  to  be  accounted  for  ? 
did  it  originate  in  each  of  these  two  isolated  localities  ?  was  the  seed  transported  over  the  intervening  land,  by 
an  agent  whose  operations  were  limited  to  the  eastern,  and  western  extremes  only  of  Antarctic  America?  or, 
have  the  individuals  that  once  tenanted  the  intervening  land,  been  destroyed  ?  Any  one  of  these  hypotheses  is  at 
first  sight  plausible,  and  the  first,  perhaps,  the  most  so,  New  Zealand  being  a  third,  and  far  more  remote,  habitat 
for  this  same  species,  which  may  thus  be  supposed  to  have  had  three  separate  origins.  Such  a  question  should 
not  be  discussed  with  reference  to  a  single  species,  but  as  one  which  concerns  all  organized  nature,  whose  pheno- 
mena are  amenable  to  general  laws.  Hypotheses,  adopted  to  account  for  exceptional  cases,  if  not  viewed  in 
reference  to  the  general  rule  from  which  these  exceptions  deviate,  are  generally  fallacious ;  and  however  much  so, 
they  still  are  apt  to  be  magnified  into  laws.  If  we  knew  only  such  plants  as  are  sporadic  (the  term  given  to  species 
which  inhabit  unconnected  and  remote  localities)  we  might,  perhaps,  be  justified  in  assuming  it  as  an  axiom,  that 
individuals  of  a  species  have  sprung,  at  isolated  localities,  from  as  many  similar  parents :  the  cases  which  appear  to 
demand  this  solution  are,  however,  exceptions  in  Botanical  Geography. 

The  study  of  the  distribution  of  any  one  species  or  genus,  or  of  the  Flora  of  any  one  country,  does  not  afford 
scope  enough  for  investigating  satisfactorily  such  a  subject  as  the  origin  of  the  individuals  of  plants.  If  species, 
genera,  and  small  natural  orders  were  sporadic,  recurring  wherever  climate  and  soil  presented  similar  conditions, 
several  points  of  origin  for  the  same  species  might  be  assumed.  But  it  is  not  so  :  species,  genera,  and  orders  are  dis- 
tributed within  geographical  limits,  according  to  their  extent :  the  great  mass  of  individual  plants  in  the  one  case,  and 
of  forms  in  the  other,  appear  to  have  sprung  from  single  centres,  in  the  former  case  from  a  common  parent,  and  to 
have  radiated  from  one  point  to  greater  or  less  distances  around  it,  in  proportion  to  the  facilities  for  migration  and 
absence  of  checks  to  diffusion.  The  explanation  of  exceptions  to  this  prevailing  rule  must  then  be  sought  in  some 
natural  cause,  capable  of  counteracting  the  general  law,  and  not  what,  if  adopted  for  the  case  of  one  species, 
must  be  conceded  with  respect  to  all,  and  consequently  force  us  to  conclude  that  two  classes  of  agents  are  required 
to  effect  one  object,  namely,  the  dispersion  of  vegetables.

This  plant  I  bebeve  to  be  specifically  the  same  with  the  North-European  and  American  A.  alpinus,  of  which 
Smith  considered  it  to  be  a  variety.    What  appeared  specific  differences,  were  pointed  out  by  Mr.  Brown  {in  Appendix 


Falhlands,  etc.]  FLOKA  ANTARCTICA.  371 

to  Parry's  1st  Voyage,  p.  184.).  Since  the  publication  of  the  last  mentioned  work  it  has  been  universally  looked 
as  an  Antarctic  species  alone,  and  its  close  affinity  with  the  A.  pratensis,  of  the  Northern  Hemisphere  was  never 
alluded  to.  The  ordinary  states  of  the  latter  plant  have  a  longer  and  less  hairy  spike ;  but  amongst  the  varieties  of 
it  which  occur  in  North  Western  Asia,  and  N.  Eastern  America,  there  is  one  wholly  undistinguishable  from  An- 
tarctic individuals ;  and  how  far  these  may  be  constantly  distinct  appears  very  doubtful  to  me.  Mi-.  Brown,  in  drawing 
up  the  characters  of  A.  alpinus,  alludes  to  his  having  gathered  Scotch  specimens  with  an  arista  twice  as  long  as  the 
glumes,  such  is  the  case  with  all  the  Antarctic  ones,  and  in  Trinius's  figure  of  A.  alpinus ;  but  is  at  variance  with 
Smith's  specific  character,  (founded  on  Mr.  Brown's  specimens)  and  with  the  ordinary  state  of  the  Scotch  plant. 
Mr.  Watson,  however,  has  gathered  the  same  aristate  variety  of-/,  alpimcs  in  Scotland,  and  has  cultivated  both  forms 
in  his  garden.  His  garden  specimens  of  both  states  are  now  before  me,  the  long  awned  one  retaining  its  characters, 
and  the  awns  of  the  common  form  decidedly  elongating  under  cultivation.  The  comparative  length  of  the  lamina 
and  vagina  of  the  uppermost  leaf,  is  also  very  variable,  even  in  A.  alpinus,  these  being  sometimes  of  equal  length, 
while  in  the  Antarctic  plant  the  lamina  is  sometimes  considerably  the  shorter ;  and,  again,  I  have  examined  an 
European  specimen  of  A.  pratensis,  in  which  the  lamina  is  even  longer  than  the  vagina.  The  other  characters  of 
A. pratensis,  used  by  Mr.  Brown,  are  those  of  the  glumes  being  acute,  and  villous  only  at  the  sides;  this  is  the  case 
with  the  British  examples  that  I  have  studied,  but  not  with  the  Siberian,  which  certainly  present  intermediate 
forms  between  this  species,  and  its  Fuegian  congener.  The  Antarctic  specimens  vary  exceedingly  in  size,  from 
four  inches,  to  two  and  even  three  feet  high ;  the  culms  are  generally  tumid  above  the  upper  leaf  and  contract 
gradually  towards  the  panicle  ;  or  they  are  slender,  cylindical  and  terete  :  the  lamina  of  the  upper  leaf  is  occasionally 
far  shorter  than  at  other  times,  equal  in  length  to,  or  much  longer  than  its  vagina.  Spikes  nearly  cylindrical, 
2-3  to  1-i  inches  long,  generally  rather  more  than  twice  as  long  as  broad,  but  now  and  then  much  narrower. 
Glumes  always  more  or  less  villous  all  over. 

Admitting  the  foliage  to  afford  no  specific  character  between  A.  alpimcs,  A.  pratensis,  and  A.  Antareticus,  and 
the  length  of  the  arista  to  be  very  variable  in  the  first  of  these,  there  remains  no  constant  character  to  distinguish 
these  three ;  for  between  A.  Antareticus  and  A.  pratensis  the  only  apparent  distinctions  lie  in  the  villosity  of  the 
glumes,  and  the  form  of  the  spike,  differences  which  do  not  hold  in  Siberian  specimens  of  the  latter.  I  have  added 
a  plate  of  the  common  Falkland  Island  state  of  this  species.

I  have  compared  this  grass  most  carefully  with  authentic  specimens  of  A.  tenuifolia  from  Persia  and  the  Caucasus, 
without  being  able  to  detect  any  further  difference  than  in  the  size  of  the  locustae,  which  in  the  Antarctic  plant  are    of 
an  inch  long,  the  Caucasian  scarcely  -Jg-.  Intermediate  between  them  is  a  common  Rocky  Mountain  species,  collected 
by  Douglas,  and  described  as  A.  exarata,  0.,  in  the  '  Flora  Boreali- Americana '  (vol.  2.  p.  239).  There  are,  however, 
two  forms  of  A.  exarata  0.,  one  from  the  east  side  of  the  Rocky  Mountains,  which  has  the  scabrid  broader  leaves 
of  the  true  A.  exarata,  and  a  distinct  upper  palea  (this  is  the  A.  Drummondi,  Torrey  MS.),  the  other  (or  Douglas's), 
from  the  west  side  of  the  dividing  ridge,  is  smaller,  more  slender,  with  small  locusta?,  and  no  upper  palea ;  it  agrees 
closely  with  the  Magellanic  plant  in  size  and  foliage,  and  bears  the  name  of  A.  tenuifolia?  Bieb.,  appended  to  it  by 
Dr.  Torrey. 

The  culms  of  A.  tenuifolia  p.  are  15  inches  to  2^  feet  long,  smooth,  erect,  and  very  slender.  Leaves  subseta-

The  lower  palea  in  my  specimens  is  obscurely  4-nerved,  or,  in  var.  /3.,  5-nerved,  with  occasionally  a  very  short 
awn,  never  projecting  beyond  the  glumes.  The  upper  palea  is  one  third  shorter  than  the  lower.  This  grass  forms 
a  very  good  pasturage,  both  in  the  upland  and  lowland  districts  about  Port  Louis,  but  is  not  very  abundant,  which 
it  may  become  if  it  be  an  introduced  plant.  The  var.  stolonifera  is  the  famous  '  Fiorin  grass,'  or  '  Squitch '  of 
Dr.  Richardson  and  the  Irish  agriculturists.

Agrostis  Antarctica  is  one  of  the  most  abundant  of  grasses  in  the  regions  it  inhabits,  especially  in  swampy 
grounds,  which  seem  particularly  favourable  to  its  growth.  It  is  also  a  very  elegant  plant,  from  its  graceful 
habit  and  the  form  of  its  nodding  panicle.  It  may  be  the  true  A.  Magellanica  of  Lamarck,  and  judging  from  its 
abundance,  appears  natural  to  suppose  so ;  but  the  very  short  upper  palea  is  not  alluded  to  in  that  author's 
description,  and  Poiret's  observation  that  the  upper  is  the  longest,  would  imply  that  there  is  no  remarkable 
difference  in  their  length.  Considering  the  invalid  nature  of  the  characters  afforded  by  the  comparative  length  of 
the  palea  in  this  genus,  it  is  probable  that  this  and  the  preceding  are  but  varieties  of  one  and  the  same  plant. 

Kerguelen's  Land  specimens  are  frequently  monstrous ;  the  lower  glume  being  then  provided  with  two 
parallel  distinct  nerves,  and  in  other  cases  I  have  seen  three  distaut  valves,  two  outer  and  one  inner.  The  lower 
palea  again  has  the  arista  sometimes  placed  on  one  side  of  its  base.

the  most  useful  grass  in  the  Falkland  Islands,  for  fodder.  It  abounds  both  in  wet  and  dry  places,  in  the  upland 
and  low  grounds,  affording  excellent  pasturage,  and  even  when  cut  and  dried  it  is  eaten  with  avidity  by  horses, 
sheep,  and  cattle.  A  very  similar  congener  inhabits  the  lofty  peak  of  Tolima,  in  New  Grenada,  north  of  the

this  plant  both  from  it  and  from  the  Tasmauian  Ii.  Antarctica,  Br. :  I  consider  them  scarcely  valid,  though  con- 
stant in  specimens  from  the  three  widely  separated  localities  they  inhabit.  In  the  Falkland  Islands  this  grass  is 
particularly  abundant,  forming  large  tufts  and  often  beds,  especially  near  running  water  and  on  wet  rocks  close  to  the 
sea,  and  is  much  frequented  by  sea-birds,  as  a  building  place.  The  scent  is  very  strong,  and  retained  in  the  dried 
specimens.  Living  plants  introduced,  by  means  of  Ward's  cases,  into  the  Kew  Gardens,  have  flourished  luxuriantly,

An  exceedingly  abundant  Falkland  Island  grass,  and  a  great  ornament  to  the  black  peat  bogs,  which  are 
frequently  clothed  with  its  elegant  purple  panicles.  The  foliage  is  too  scanty  and  of  too  rigid  a  texture  to  afford 
good  pasturage. 

I  do  not  detect  any  difference  between  Falkland  Island  aud  European  specimens.  Mr.  Watson  remarks  that 
this  is,  perhaps,  the  A.  uliginosa,  Weihe  ;  a  plant  I  do  not  know,  but  quoted  by  Kunth  as  synonymous  with 
A.flexuosa.

There  are  specimens  of  this  species  in  the  Hookerian  Herbarium,  marked  as  collected  in  the  Falkland  Islands 
by  Admiral  D'Urville,  and  others  sent  from  Valdivia  by  Mr.  Bridges.  The  plant  is  unquestionably  the  common 
European  "  Silver  Hair  Grass  ",  aud  accidentally  introduced,  for,  as  Mr.  Curtis  remarks,  "  so  insignificant  an  annual 
can  hardly  be  worth  cultivating."

Tbis  elegant  grass,  appropriately  named  A.  Antarctica,  attains  a  higber  southern  latitude  than  any  other 
flowering  plant,  being  the  only  phaenogamic  species  that  inhabits  the  South  Shetland  Islands.  Kerguelen's  Land  in 
latitude  48°  is  its  northern  luuit;  but  that  Island  being  situated  in  a  longitude  where  the  rigour  of  the  Antarctic 
climate  extends  further  north  than  in  any  other,  this  grass  is  even  there  more  typical  of  the  frigid  zone  than  the 
latitude  would  indicate,  and  always  seeks  the  most  sheltered  places.  In  the  Falkland  Islands  again,  the  most 
temperate  region  it  inhabits,  it  invariably  avoids  shelter,  bemg  found  chiefly  in  open  marshy  places  near  the  sea, 
fully  exposed  to  the  violence  of  the  winds.

sea,  /.  D.  H.     Falkland  Islands,  most  abundant,  D'  Urville,  J.  B.  R. 

In  the  first  part  of  this  work  I  have  given  the  geographical  range  of  the  Trisetmn  subspicatum,  when  noticing 
it  as  a  native  of  Campbell's  Island ;  at  which  time  I  was  not  aware  of  any  other  South  American  station  for  it  than 
the  Andes  of  Peru.  Since  then  1  have  seen  several  specimens  collected  both  in  the  Cordillera  of  Columbia  and  in 
Mexico,  whence  it  is  evident  that  this  plant,  bke  many  common  to  the  opposite  temperate  zones,  has  availed 
itself  of  the  direct  communication  afforded  by  the  Andes  of  the  American  continent  for  migrating  from  the 
Northern  to  the  Southern  Hemisphere.  Its  great  abundance  in  the  New  World  and  especially  in  the  extreme  South 
of  America,  coupled  with  its  rarity  in  the  southern  regions  of  the  Old  World,  where  it  is  only  known  on  the  tops 
of  the  mountains  of  Campbell's  Island,  seem  to  indicate  its  having  been  transmitted  from  east  to  west,  or  against 
the  course  of  the  prevailing  winds  in  the  Antarctic  regions.

A  very  elegant  species,  of  which  I  regret  having  seen  but  one  culm,  which  wants  the  rooting  portion.  It  is 
nearly  allied  to  the  United  States  Avena  palustris,  Mich. ;  from  which  it  may  readily  be  distinguished  by  the  smaller 
locusta?,  more  exserted  florets,  and  unequal  glumes.

and  Solander;  Falkland  Islands,  abundant  [vars.  2  and  5). 

I  cannot  ascertain  the  identity  of  this  species  with  the  European  P.  pratensis,  so  satisfactorily  as  that  of  the 
former  with  P.  nemoralis  j  nevertheless,  the  more  the  present  grass  is  studied,  the  more  difficult  it  appears  to 
detect  specific  characters.  The  five  varieties  enumerated,  appear  all  to  belong  to  one  plant ;  except,  perhaps,  the 
var.  1,  in  which  the  ligula  of  the  upper  leaf  is  oblong  as  in  the  European  P.  alpina,  to  a  North  American  state  of 
which  I  should  have  referred  that  variety,  had  its  florets  not  been  webbed,  a  character,  which,  though  of  trifling- 
importance,  (perhaps  even  less  than  the  form  of  the  ligula)  does  not  exist  in  any  of  the  numerous  individuals  of 
P.  alpina  that  I  have  examined. 

In  British,  and,  indeed,  in  European  examples  of  P.  alpina,  we  are  accustomed  to  see  a  small  panicle  of 
short  and  broad  flowers,  with  a  different  aspect  to  that  of  P.  pratensis ;  but  North  American  individuals  are  subject 
to  great  variations  in  the  size  and  outline  of  the  panicle,  so  great  that  without  connecting  forms  it  would  be  very 
difficult  to  recognize  them.  Mr.  Watson  is  equally  persuaded  with  myself  of  the  close  affinity  between  this  An- 
tarctic Poa  and  P.  alpina,  though  neither  of  us  can  adduce  a  tangible  character  beyond  the  webbed  florets 
to  separate  the  plants  of  Arctic  and  Antarctic  America.  I  have  not  seen  any  of  these  species  from  the  intervening 
Cordillera,  a  circumstance  of  little  importance,  the  Graminea  of  these  regions  having  been  very  much  neglected  by 
all  collectors  since  the  period  of  the  travels  of  the  illustrious  Humboldt.

A  peculiar  species,  allied  to  the  last  and  to  no  other  with  which  I  am  acquainted.  The  obliquely  truncated  apex 
of  the  lower  palea  in  the  T.  Kerguelensis,  is  here,  as  it  were,  exaggerated  by  that  organ  becoming  decidedly  though 
minutely  trifid  at  the  apex,  as  iu  the  European  Triodia  decumhens,  a  genus  to  which  both  species  ought  from  this 
circumstance  be  referred,  and  from  their  peculiar  panicle  and  locustse. 

In  habit  the  similarity  between  this  plant  and  the  former  is  very  great,  and  apparent  in  the  size,  foliage,  and 
locality  they  both  affect,  iu  their  respective  Islands ;  the  differences  in  the  details  of  the  florets,  are,  on  the  other 
hand,  sufficiently  wide.

A  very  handsome  grass,  which,  perhaps,  properly  belongs  to  Poa,  though  the  palea?  are  so  decidedly  acu- 
minate that  I  prefer  retaining  it  under  Festuca.  The  two  varieties  enumerated  are  not  always  constant  to 
the  characters  assigned  to  them. 

In  general  appearance  this  species  resembles  the  British  Aim  caspilosa,  which  is  frequently  similarly  viviparous 
on  the  mountains,  and  the  modifications  the  palea?  consequently  undergo  both  in  these  and  some  other  grasses,  is  a 
subject  well  worthy  of  study.  When  the  inflorescence  becomes  foliaceous,  the  palea  itself,  which  is  distinctly 
5 -nerved  is  represented  by  the  (equally  5 -nerved)  vagina  of  the  leaf;  the  ligula  of  the  latter  holds  the  position  of 
the  membranous  and  often  divided  apex  of  such  a  palea  as  that  of  Aim,  whilst  the  lamina  answers  to  a  dorsal  awn  ; 
or  rather,  in  the  case  of  Festuca  Fuegiana,  to  five  awns  (such  as  those  of  Polypogon  Chonoticus,  p.  374),  united  by 
parenchyma.  That  the  arista  of  the  lower  palea  in  grasses  is  the  produced  mid-rib  of  a  modified  leaf,  is  perhaps 
generally  admitted,  but  the  exact  relation  of  the  apex  of  the  palea  to  a  ligula  is  not  so  evident  in  all  aristate  florets, 
as  it  is  in  those  where  the  middle  nerve  is  not  percurrent  but  separates  from  the  palea  in  the  form  of  an  awn.  One 
apparent  objection  to  this  view  may  be  adduced  in  the  distinctly  articulate  awn  of  Coryneplioriis  and  Stipa,  which 
may  further  be  supposed  favourable  to  M.  Easpail's  theory,  that  the  mid-rib  of  the  palea  is  an  axis  of  developement 
in  cohesion  with  the  bracts ;  such  articulations  are,  however,  exceptional,  and  their  position  I  am  inclined  to  consider 
as  indicating  the  point  of  union  of  the  leaf  with  the  vagina,  where  an  angle  is  always  observable.  Viviparous  grasses, 
too,  would  be  expected  to  produce  constantly  additional  organs  from  the  portion  of  the  transformed  palea  beyond 
the  ligula,  if  M.  Easpail's  view  were  correct,  but,  this,  on  the  contrary,  is  seldom  the  case.  There  is  a  similarity 
between  the  palea  of  a  viviparous  grass  and  the  upper  bract  of  each  spikelet  in  some  Marisci :  for  in  them  the 
dilated  lower  portion  of  the  bract,  or  the  true  continuation  of  the  rachis,  somewhat  resembles,  without  however 
being  strictly  analogous  to,  the  lower  palea  of  a  locusta,  and  the  uppermost  flower  is  borne  in  a  position,  similar  to 
the  axle  of  the  ligula  on  the  leaf  of  a  grass.

Next  to  the  Tussock,  the  present  is  the  largest  grass  in  the  Falkland  Islands,  though,  like  that  plant,  it  is  very 
variable  in  size.  The  largest  specimens  are  tlu-ee  or  even  four  feet  high,  the  smaller  scarcely  one.  Though  a 
conspicuous  object,  its  varieties  are  not  always  easily  recognizable ;  for  the  most  prominent  characters  of  the 
typical  state,  which  are  the  great  size  of  the  locusta?,  and  the  narrow  palea?  and  glumes  with  slender  attenuated 
apices,  are  quite  fallacious.     All  my  large  specimens  of  var.  a  have  either  a  minute  turbinate  ovarium  or  a  small

caryopsis,  and  are  never  staminiferous ;  thus  it  is  very  possible  that  some  of  the  varieties  enumerated  may  be  the 
males  of  this,  the  largest  form. 

M.  Brongniart  has  suggested  the  propriety  of  erecting  the  present  plant,  together  with  the  F.  Antarctica,  into 
a  new  genus,  and  they  certainly  are  more  nearly  allied  to  one  another  than  to  any  of  their  congeners  ;  still  I  doubt 
the  possibility  of  finding  any  character  of  generic  value  common  to  them  both.  They  also  resemble  some  South 
Brazilian  and  Patagonian  grasses,  as  the  Poa  lanuginosa,  Nees,  and  other  undescribed  species. 

If  I  had  seen  only  single  specimens  of  the  different  varieties,  I  should  certainly  have  considered  three  of  them 
to  be  as  many  species ;  but  a  very  large  collection  of  individuals,  from  various  parts  of  the  Island,  has  convinced 
me,  that  neither  the  comparative  length,  breadth,  or  attenuation  of  the  apices  of  the  glumes  and  paleas,  nor  the 
woolliness  of  the  base  of  the  florets,  or  length  of  the  leaves,  afford  any  grounds  for  a  further  subdivision ;  at  least  I 
have  been  unable  to  effect  such,  either  when  examining  the  fresh  specimens,  or,  more  lately,  when  comparing  the 
dried  ones.  Dissimilar  as  the  following  plant  appears,  I  am  not  at  all  positive  of  its  claims  to  the  rank  of  a 
separate  species ;  for  some  of  its  characters  may  be  due  to  the  different  locality  it  generally  affects ;  and  specimens 
of  the  var.  8.  approaching  the  F.  Arundo  far  too  nearly. 

Though  a  large  and  very  handsome  grass,  the  Festuca  Arundo  is  so  harsh  and  rigid  as  to  be  quite  unpalateable 
to  cattle ;  this  is  the  more  obvious  from  its  often  growing  side  by  side  with  the  nutritious  Tussock,  out  of  the 
same  sand-heap.

Few  botanists  would,  I  think,  venture  to  separate  any  of  the  varieties  enumerated  above  from  F.  Antarctica, 
and  very  many  others  would  unite  all  with  the  preceding  species,  and  perhaps  correctly.  M.  Kunth  describes  a 
specimen  of  this  grass  (received  from  D'Urville)  as  having  the  flosculi  naked  at  the  base,  exactly  as  in  my  varieties 
y.  and  8.  {En.  Plant.  Suppl.  p.  340).     The  locustse  vary  iu  my  specimens,  being  from  two-  to  four-flowered.

The  commonest  grass  in  Kerguelen's  Land  and  a  very  valuable  one,  affording  a  rich  and  abundant  fodder. 
The  tendency  in  the  palea  to  become  toothed  on  each  side  towards  the  apex,  and  the  distichous,  long,  and  particularly 
rich  foliage,  show  its  affinity  with  the  Tussock  and  with  the  Festuca  foliosa  of  Lord  Auckland's  group,  which  chiefly 
differs  from  this  in  its  larger  panicle.  These  three  grasses  are  certainly  representatives  of  one  another,  and  all 
typical  of  moist  Insrdar  climates ;  their  northern  analogues  are  evidently  the  F.  Bonax,  Lowe,  of  Madeira,  and

Falklands,  etc.]  FLORA  ANTARCTICA.  385 

Though  much  has  lately  been  written  in  the  '  Journal  of  Botany  '  upon  this  plant,  the  famous  Tussock  Grass 
of  the  Falkland  Islands,  it  appears  advisable  to  sum  up  here  the  principal  facts  connected  with  its  history. 

Commerson  was  doubtless  the  discoverer  of  it  in  the  Strait  of  Magalhaens,  in  1767,  and  it  has  been  gathered 
in  Fuegia  by  several  succeeding  voyagers ;  but  as  it  nowhere  forms  so  conspicuous  a  feature  as  in  the  Falkland 
Islands,  it  is  most  appropriately  considered  in  reference  to  them  alone. 

A  French  colony  was  established  on  the  Falklands,  by  Admiral  Bougainville,  in  1766,  when  cattle  and  horses 
were  landed,  which,  no  doubt,  soon  manifested  a  predilection  for  this  noble  grass.  Pernetty,  the  historiographer 
of  the  Voyage,  in  describing  the  remarkable  plants  of  those  Islands,  alludes  particularly  to  it  under  the  name  of 
"Glayeul";  but  it  was  not  until  the  recent  colonization  of  the  Falklands  by  the  British  that  attention  was  particu- 
larly directed  to  the  Tussock,  in  consequence  of  accounts  forwarded  to  the  Colonial  Office  by  Governor  Moody,  and 
to  the  Admiralty  by  the  Antarctic  Expedition. 

The  peculiar  mode  of  growth  of  Bactylis  ctpsjiitosa  enables  it  to  thrive  in  pure  sand,  and  near  the  sea,  where  it 
has  the  benefit  of  an  atmosphere  loaded  with  moisture,  of  soil  enriched  by  decaying  sea-weeds,  of  manure,  which 
is  composed  in  the  Falkland  Islands  of  an  abundant  supply  of  animal  matter  in  the  form  of  Guano,  and  of  the 
excrements  of  various  birds,  who  deposit  their  eggs,  rear  their  young,  and  find  a  habitation  amongst  the  groves  of 
Tussock.  Its  general  locality  is  on  the  edges  of  those  peat-bogs  which  approach  the  shore,  when  it  contributes 
considerably  to  the  formation  of  peat.  Though  not  universal  along  the  coast  of  these  Islands,  the  quantity  is  still 
prodigious,  for  it  is  always  a  gregarious  grass,  extending  in  patches  sometimes  for  nearly  a  mile,  but  seldom 
seen  except  within  the  influence  of  the  sea  air.  This  predilection  for  the  ocean  does  not  arise  from  an  incapacity 
to  grow  and  thrive  except  close  to  the  salt  water,  but  because  other  plants,  not  suited  to  the  sea-shore,  already 
cover  the  ground  in  more  inland  localities,  and  prevail  over  it  :  I  have  seen  the  Tussock  on  inaccessible  cliffs  in 
the  interior,  having  been  brought  there  by  the  birds  and  afterwards  manured  by  them ;  and,  when  cultivated,  it 
thrives  both  in  the  Falklands  and  in  England,  far  from  the  sea. 

I  know  of  no  grass  likely  to  yield  nearly  so  great  an  amount  of  nourishment  as  the  Tussock,  when  thoroughly 
established ;  in  proof  of  which  I  quote  my  friend  Governor  Moody's  printed  report,  for  the  truth  of  which  I  can 
vouch,  both  from  my  own  experience  and  from  his  having  kindly  given  me  ample  means  for  judging  of  the  correctness 
of  his  interesting  and  useful  observations,  when  drawing  up  the  report  from  which  the  following  extract  is  made. 

"During  several  long  rides  into  the  country  I  have  always  found  the  Tussock  flourishing  most  rigorously  in 
spots  exposed  to  the  sea,  and  on  soil  unfit  for  any  other  plant,  viz.  the  rankest  peat-bog,  black  or  red.  It  is  wonderful 
to  observe  the  beaten  foot-paths  of  the  wild  cattle  and  horses,  marked  bkc  a  foot-track  across  fields  in  England, 
extending  for  miles  over  barren  moor-land,  but  always  terminating  in  some  point  or  peninsula  covered  with  this 
favourite  fodder  ;  amid  which,  one  is  almost  certain  to  meet  with  solitary  old  bulls,  or  perhaps  a  herd  of  cattle ; 
very  likely,  a  troop  of  wild  horses,  just  trotting  off  as  they  scent  the  coming  stranger  from  afar.  To  cultivate  the 
Tussock  grass  I  should  recommend  that  its  seeds  be  sown  in  patches,  just  below  the  surface  of  the  earth  and  at 
distances  of  about  two  feet  apart ;  it  must  afterwards  be  weeded  out,  for  it  grows  very  luxuriantly,  frequently  attaining 
a  height  of  six  or  seven  feet.  It  should  not  be  grazed,  but  cut  or  reaped  in  bundles.  If  cut,  it  quickly  shoots 
again  ;  but  is  much  injured  by  grazing;  for  all  animals,  especially  pigs,  tear  it  up  to  get  at  the  sweet  nutty-flavoured 
roots.  I  have  not  tried  how  it  would  be  relished  if  made  into  hay,  but.  cattle  will  eat  the  dry  thatch  oft'  the  roof 
of  a  house  in  winter  ;  their  preference  to  Tussock  grass  being  so  great  that  they  scent  it  a  considerable  distance 
and  use  every  effort  to  get  at  it.  Some  bundles,  which  had  been  stacked  in  the  yard  at  the  back  of  Government 
House,  were  quickly  detected,  and  the  cattle  in  the  village  made,  every  night,  repeated  attempts  to  reach  them, 
which  occasioned  great  trouble  to  the  sentry  on  duty." 

Since  the  above  was  written,  the  Tussock  has  been  used  abundantly  when  made  into  hay,  being  preferred  by 
cattle  even  to  the  green  state  of  any  of  the  other  excellent  grasses  in  the  Falklands.  Governor  Moody  informs 
me  that  in  his  garden  it  grows  rapidly  and  improves  by  cutting.

There  is,  however,  one  draw-back  to  the  value  of  the  Tussock ;  it  is  a  perennial  grass,  of  slow  growth,  and 
some  disappointment  has  already  been  experienced  in  England  from  this  cause.  Each  Tussock  consists  of  many 
hundreds  of  culms,  springing  together  from  a  mass  of  roots,  which  have  required  a  long  series  of  years  to  attain  their 
great  and  productive  size.  Oar  cultivated  specimens  in  the  Royal  Gardens  of  Kew,  now  nearly  three  years  old, 
are  in  a  fair  way  of  becoming  good  Tussocks ;  for  the  quantity  of  stems  from  eirch  root,  the  produce  of  one  seed, 
is  incalculably  more  than  any  other  grass  throws  np,  and  these  are  already  forming  a  ball  of  root-fibres  which  in 
time  will  form  a  mound ;  but  this  ball,  now  scarcely  sis  inches  across  and  not  two  in  height,  must  have  grown 
to  six  or  eight  feet  high,  with  a  diameter  of  three  or  four  feet ;  instead  of  forty  culms  there  must  be  four  hundred ; 
and  the  leaves,  now  three  feet  long,  must  attain  seven ;  ere  the  Tussock  of  England  can  compete  with  its 
parent  in  the  Falklands.  Though,  however,  the  stoles  (if  I  may  so  call  the  matted  roots  of  this  grass)  in 
the  most  vigorous  native  specimens  attain  a  height  of  seven  feet,  it  is  certain  that  they  are  very  productive  before 
they  have  reached  two  or  three.  By  the  time  the  leaves  have  gained  their  great  size,  the  bases  of  the  culms  are 
nearly  as  broad  as  the  thumb,  and  when  pulled  out  young,  they  yield  an  inch  or  two  of  a  soft,  white,  and  swi  et 
substance,  of  the  flavour  of  a  nut,  and  so  nutritious,  that  two  American  sealers,  who  deserted  a  vessel  in  an  unfre- 
quented part  of  the  Falklands,  subsisted  on  little  else  for  fourteen  months. 

Again,  the  Tussock-grass  field,  wheu  fully  established,  must  not  be  grazed  indiscriminately  by  cattle.  These 
creatures  and  the  pigs  have  already  diminished  its  abundance  in  the  Falklands ;  for,  after  devouring  the  foliage, 
they  eat  down  the  stumps  of  the  culms,  greedily  following  them  into  the  heart  of  the  mass  of  roots  from  which 
they  spring,  for  the  sake  of  the  white  core  just  described ;  the  rain-water  lodges  in  the  cavity  thus  formed,  and 
decay  so  surely  follows,  that  I  have  seen  nearly  half  a  mile  of  Tussock-grass  plants  entirely  destroyed  by  no  other 
means. 

Although  iu  the  Falklands  this  plant  will  grow  on  pure  sand  near  the  sea,  and  there  reach  as  great  a  size  as 
on  any  other  soil,  it  is  not  likely  to  do  so  in  the  drier  climate  of  Britain,  where  the  absence  of  an  equally  humid 
atmosphere  must  be  artificially  remedied.  A  wet,  Ught,  peaty  soil  has  in  England  been  found  to  favour  its  growth  ; 
sea-weed  manure  might  probably  be  added  with  advantage,  and  certainly  guano.  Slow  its  progress  assuredly  is, 
but  it  may  be  hastened  by  such  stimulants.  In  the  mean  time  the  cultivator  has  no  just  cause  for  complaint ; 
the  plant  is  already  increasing  unusually  at  the  base,  and  thence  sending  up  many  more  culms  than  other  grasses, 
though,  springing  from  one  small  base,  they  do  not  make  such  a  show,  but  form  a  compact  mass  of  living  roots 
which  in  the  case  of  other  Graminea?  would  spread  over  ten  times  the  area  that  this  occupies,  and  they  annually 
increase  in  vigour  and  productiveness.  And,  lastly,  it  must  be  borne  in  mind  that  the  farmer  here  obtains 
an  enormous  crop  from  a  very  small  surface.  Each  great  Tussock  is  the  produce  of  one  seed  and  is  an  isolated 
individual  plant,  which,  though  standing  upon  perhaps  only  two  square  yards  of  ground,  yields  annually  a  produce 
equal  to  that  of  a  much  greater  surface  of  land,  if  cropped  with  hay  or  clover.  The  number  of  seeds  required  to 
stock  an  acre  in  Tussock  and  one  in  grass  is  in  the  proportion  of  tens  to  thousands  ;  and  we  may  be  well  content 
to  know  that  the  number  of  months  required  to  ensure  a  profitable  return  is  not  in  the  same  ratio. 

There  are  few  plants  which  from  perfect  obscurity  have  become  objects  of  such  interest  as  this  grass.  The 
Tussock  in  its  native  state  seems  of  almost  no  service  in  the  animal  economy.  A  little  insect,  and  only  one  that 
I  observed,  depends  on  it  for  sustenance ;  and  a  bird,  no  bigger  than  the  sparrow,  robs  it  of  its  seeds ;  a  few  sea- 
fowl  build  amongst  the  shelter  of  its  leaves  :  penguins  and  petrel  seek  hiding-places  amongst  the  roots,  because  they 
are  soft  and  easily  penetrated,  and  Sea-lions  cower  beneath  its  luxuriant  foliage  :  still,  except  the  insect,  I  know 
no  animal  or  plant  whose  extinction  could  follow  the  absence  of  this,  the  largest  vegetable  production  in  the 
Falklands,  which  does  not  even  support  a  parasitical  fungus.  These  same  sea-birds  breed  and  burrow  where  no 
Tussock  grows ;  rocks  elsewhere  suit  the  Sea-lion's  habits  equally  well ;  and  the  sparrow,  which  subsists  on  other 
food  eleven  months  of  the  year,  could  surely  make  shift  without  this  for  a  twelfth.  Certain  it  is,  that  the  Tussock 
might  yet  be  unknown  and    unprized  amongst  plants,  if  cattle  had  not  been  introduced  to  its  locality  by  man  ;

who  thus  became,  first  the  injurer,  and  then  the  protector  and  propagator  of  the  existence  of  this  noble  grass  ;  for  the 
herbivorous  quadrupeds  which  he  carried  to  the  Falklands  and  left  there,  were  surely  extirpating  the  Tussock,  when 
man  returned,  and,  by  protecting,  perpetuating,  and  transporting  it  to  other  countries,  he  has  widely  dispersed  it. 
It  appears  singular  that  so  striking  a  grass  should  abound  where  there  is  no  native  herbivorous  animal  to  profit  by 
its  luxuriance ;  but  it  is  no  less  certain  that  had  not  civilization  interfered,  the  Tussock  might  have  waved  its  green 
leaves  undisturbed  over  the  waters  of  the  stormy  Antarctic  Ocean,  for  ever  perhaps,  or  until  some  fish,  fowl,  or 
seal,  should  be  so  far  tempted  by  the  luxuriance  of  the  foliage  as  to  transgress  the  laws  of  nature,  and  to  adapt  its 
organs  to  the  digestion  and  enjoyment  of  this  long-neglected  gift  of  a  bounteous  Providence. 

It  must  appear  strange  to  all  who  know  grasses  oidy  in  the  pastures  of  England,  that  the  patches  of  Tussock 
resemble  nothing  so  much  as  groves  of  small  low  Palm-trees  !  This  similarity  arises  from  the  matted  roots  of  the 
individual  plants  springing  in  cylindrical  masses,  always  separated  down  to  the  very  base,  and  throwing  out  a  waving 
head  of  foliage  from  each  summit.  Bogs  and  damp  woods  in  Britain  very  frequently  produce  a  Sedge  (Carer 
paniculata),  whose  mode  of  growth  is,  on  a  small  scale,  identical  with  that  of  the  Tussock-Grass,  and  to  which  the 
name  of  Tussock  is  applied.  I  have  seen  them  two  to  three  feet  above  the  ground,  in  South  Wales  ;  and  if  they 
were  higher,  larger,  and  placed  closer  together,  the  general  resemblance  would  be  complete.  The  effect  in  walking 
through  a  large  Tussock  grove  is .  very  singular,  from  the  uniformity  in  height  of  these  masses,  and  the  narrow 
spaces  left  between  them,  which  form  an  effectnal  labyrinth ;  leaves  and  sky  are  all  that  can  be  seen  overhead, 
and  their  curious  boles  of  roots  and  decayed  vegetable  matter  on  both  sides,  before  and  behind ;  except  now  and 
then,  where  a  penguin  peeps  forth  from  his  hole,  or  the  traveller  stumbles  over  a  huge  Sea-lion,  stretched  along  the 
ground,  blocking  up  his  path.

tridentate  at  the  apex,  with  the  middle  tooth  sometimes  produced  into  a  short  awn ;  it  is,  however,  always  hairy, 
as  may  be  seen  in  Siberian,  Arctic  American,  and  Rocky  Mountain  plants,  which  latter,  indeed,  are  sometimes 
villous.  The  North  American  specimens  are  generally  larger  than  the  European.  This  species  is  also  a  native  of 
Cape  Fairweather  on  the  Patagonian  coast,  and  exceedingly  abundant  throughout  Fuegia  and  the  Falkland  Islands.

390  FLORA  ANTARCTICA.  [Fueffia,  the 

Hab.  Clionos  Archipelago ;   C.  Danoin,  Esq. 

Even  amongst  the  Ferns  we  have  much  peculiarity  attending  the  Flora  of  S.W.  Chili  and  Fuegia.  I  have 
elsewhere  alluded  to  the  botanical  division  of  that  line  of  coast  into  a  northern  and  southern  portion,  differing 
specifically  in  their  productions,  but  not  generically  to  any  very  great  amount.  These  two  divisions  are,  1st,  the 
Valdivian  or  Chilotian,  which  stretches  from  Concepcion  to  Cape  Tres  Montes ;  and,  2nd,  the  Magellanic  or  Fuegian. 
commencing  at  Cape  Tres  Montes  and  terminating  at  Cape  Horn.  From  the  lower  latitude  and  consequently 
higher  temperature  of  the  northern  of  these  two  countries,  and  from  its  greater  surface,  containing  also  mountains 
that  reach  the  limits  of  perpetual  snow,  its  Flora  is  by  very  far  the  richest,  including  a  larger  proportion  of  the 
Fuegian  plants  than  Fuegia  does  of  the  Chilotian.  There  are  also  many  species,  which,  though  conspicuous  in 
the  southern  Flora,  are  either  unknown  even  on  the  Alps  of  the  northern,  or  appear  there  only  under  very  different 
aspects. 

Many  more  species  common  to  both  these  divisions,  Fuegian  plants  especially,  prevail  through  the  whole  line 
of  coast,  than  its  great  extent  would  lead  us  to  expect.  This  proceeds  from  a  mutual  interchange  of  individuals 
between  two  countries  whose  Floras  may  be  supposed  to  have  been  originally  quite  distinct.  The  inosculation  of 
the  Floras  is  most  conspicuous  at  Cape  Tres  Montes  and  the  Chonos  Archipelago,  and  is  not  accompanied  by  any 
tendency  in  those  species,  which  there  come  into  juxta-position,  to  change,  each  into  that  which  represents  it  in 
the  other.  The  union  or  mingling  is  complete,  but  there  is  no  blending  of  two  species,  no  obliteration  of  specific 
characters,  nothing  to  indicate  either  that  the  peculiar  plants  of  one  country  have  originated  from  what  pre-existed  in 
the  other  under  a  different  form ;  or,  still  less,  that  all  have  sprung  from  one  common  source,  lower  in  the  scale 
of  organization.

A  species  exhibiting  a  singular  predilection  for  those  insidar  and  peninsular  localities,  which  terminate  the 
continents  in  the  Southern  Ocean.  Thus  it  occurs  only  at  the  very  southern  extremity  of  America  and  Africa  ;  at 
Ceylon,  which  is  nearly  the  southernmost  land  of  the  vast  Indian  empire ;  in  Tasmania,  which  is  an  analogous 
position  in  Australasia ;  and  in  New  Zealand  and  Lord  Auckland's  group,  which  bear  the  same  geographical 
relation  to  Polynesia.  As  it  also  inhabits  Bourbon  and  the  Mauritius,  it  appears  to  exist  all  round  the  world, 
resting  on  the  highest  southern  lands  of  each  longitude.

A  plant  which  I  have  never  seen,  though  I  diligently  sought  for  it  in  the  Falkland  Islands.  It  is  remarkable 
that  both  the  French  Naturalists  who  met  with  it,  should  have  faded  to  notice  the  Hymenophyllum  Wihoni,  which 
is  sufficiently  abundant,  and  generally  accompanies  the  following  species.

of  Good  Hope.     Its  aversion  to  damp  or  uniform  heat  is  conspicuously  displayed  in  its  not  being  a  native  of  New

A  species  apparently  impatient  of  cold,  for  though  inhabiting  the  damp  west  coast  of  Chili,  as  far  south  as  the 
Chonos  Archipelago  and  the  dry  climate  of  Patagonia,  reaching  there  the  latitude  of  Port  St.  Elena,  it  neither  enters 
the  Strait  of  Magalhaens,  nor  occurs  in  the  Falkland  Islands  or  Fuegia.  It  is  almost  universally  diffused  throughout 
the  Tropics,  and  the  temperate  regions  of  the  southern  hemisphere.

The  only  specimen  wdiich  I  have  seen  is  imperfect,  but  appears  merely  a  variety  of  the  A.  vestitwm,  with  rather 
narrower  and  more  deeply  cut  pinnules,  which  are  acute,  but  not  pungent  or  spinulose ;  the  segments  of  the  pinnules 
also  are  narrower,  and  the  whole  frond  smaller.  In  other  respects,  and  particularly  in  the  clothing  of  the  stipes, 
rachis,  Sec,  it  exhibits  all  the  characters  of  the  species  I  have  referred  it  to,  which  is  a  native  of  Juan  Fernandez 
and  Chiloe.  I  am  not  prepared  to  say  how  far  all  may  be  distinct  from  the  British  A.  aculeatum,  the  incisions 
of  the  broader  mucronate  pinnules  in  the  European  plant  are  closer,  and  all  aculeate,  which  is  not  the  case  with  the 
typical  states  of  A.  vestitum ;  and  the  clothing,  too,  is  different. 

This  species  is  represented  by  the  A.  vemtstum,  Homb.  and  Jacq.,  in  Lord  Auckland's  group,  and  by  A.proli-

all  which  countries  it  retains  its  characters  very  markedly,  and  is  altogether  a  most  distinct  species.  The  Blechium 
horenle  is  evidently  its  representative  in  the  northern  hemisphere,  and  is  very  similar  in  size,  form,  and  habit, 
though  abundantly  distinct  in  the  nature  of  its  involucre.

examined  what  appears  to  be  the  same  from  British  Guiana  (possibly  a  distinct  species),  from  Brazil,  and  La  Plata, 
on  the  east  coast  of  South  America ;  and  from  Peru,  Juan  Fernandez,  and  Chili,  on  the  west ;  it  also  inhabits

the  sori ;  this  character,  together  with  the  stout,  rigid,  and  very  coriaceous  habit,  appear  to  indicate  its  being  a  native 
of  drier  places  than  the  former.  It  has  hitherto  been  found  only  in  the  Falklands,  in  plains  of  Valdivia,  and  on

The  Falkland  Island  specimens  are  perfectly  identical  with  others  of  British  growth,  but  the  var.  Saururus 
is  so  different  from  any  aspect  of  L.  Selago  found  in  Europe,  that  it  requires  the  most  perfect  suite  of  specimens, 
showing  the  gradual  passage  of  the  one  into  the  other,  to  prove  their  common  origin.  Such,  however,  exist, 
especially  in  volcanic  islands,  which  seem  peculiarly  favourable  to  the  production  of  this  variety. 

In  its  largest  and  handsomest  form,  the  var.  Saururus  inhabits  the  Andes  of  Peru,  the  Island  of  Bourbon,  and 
Kerguelen's  Land.  A  more  slender  state,  but  not  slenderer  than  what  occurs  amongst  Andes  specimens,  is  found  in 
Tristan  d'Acunha,  St.  Helena,  and  in  some  of  the  West  Indian  Islands. 

The  narrow  form  of  var.  Saururus  was  brought  from  St.  Helena  as  early  as  1702,  and  given  to  Dillenius, 
who  figured  it.  On  the  Andes,  and  there  alone,  the  Selago  division  of  Lgcopodia  assume  a  deep  brick-red  colour, 
which,  however,  affords  no  specific  character,  for  the  Saururus  is  as  often  wholly  green  as  red,  and  at  other  times  is 
only  tinged  with  the  latter  colour  at  the  apices  of  the  leaves ;  and  this  is  the  case  with  the  Kerguelen's  Land  speci- 
mens. It  is  difficult  to  imagine  the  cause  for  this  tint  of  plants.  On  the  gloomy  Island  of  Desolation,  it  cannot  be 
due  to  the  tropical  sun,  nor  to  colouring  matter  contained  in  the  soil,  for  it  also  occurs  in  two  species  which  I 
believe  are  always  parasitical.

I  have  in  the  former  part  of  this  work  given  my  reasons  at  length  for  assigning  these  varieties  to  L.  clavatum. 
The  var.  fasligiatitm  is  a  plant  of  a  warmer  climate  than  the  var.  Magellanicum,  which  inhabits  not  only  the  low-lands 
of  Fuegia,  the  Falklands,  and  Kerguelen's  Land,  but  also  the  lofty  heights  of  the  Cordillera  of  Peru  and  Colombia, 
and  the  mountains  of  New  Zealand,  Tasmania,  and  Lord  Auckland's  group.

After  a  careful  comparison  of  this  plant  with  Engbsh  specimens  of  C.fiexilis,  I  consider  them  to  be  the  same 
species,  and  am  confirmed  in  this  opinion  by  my  friend  Mi-.  Wilson,  who  has  studied  the  British  species  of  this 
difficult  genus  very  carefully  ;  he  says,  that  the  points  at  the  apices  of  the  branches  are,  perhaps,  longer  than 
common  in  the  Antarctic  specimens.     It  is  probably  not  an  unfrequent  plant  in  the  southern  temperate  zone.

of  Weber  and  Mohr  (Bot.  Tasch.  p.  383),  nor  their  citation  of  Dillenius  (Hist.  Muse.  t.  73.  f.  40),  as  a  synonym  for 
A.  rupestris  instead  of  A.  Rothii,  tends  to  prove  that  these  authors  understood  the  species.     The  illustrative  figures

396  FLOKA  ANTAECTICA.  [Fuegia,  the 

and  observations  show  tbat  A.  alpina  of  Weber  and  Mohr  (Bot.  Tamil,  t.  11.  f.  3,  5),  is  only  a  state  of  A.  rupestris, 
with  leaves  spreading  in  all  directions.  This  is  confirmed  by  the  fact  that  A.  alpina  of  Mougeot  and  Nestler 
(Stirp.  Crypt.  Voges.  no.  115),  is  that  very  form  of  A.  rupestris  to  which  we  allude.  The  figures  of  Dillenius  doubtless 
refer  to  A.  alpina  ;  but  the  absence  of  a  separate  figure  of  A.  rupestris,  and  the  remark,  "  in  rupibus  surculi  e  fusco 
rufescunt"  (p.  507),  prove  that  this  author  considered  both  these  as  varieties  of  one  species.  The  true  A.  alpina 
may  always  be  known  from  A.  rupestris  by  its  obovate  dark  glossy  leaves,  and  its  longer  and  more  robust  stems.

With  some  hesitation  we  venture  to  separate  this  from  A.  alpina,  on  account  of  the  more  gradual  acumination 
of  its  leaves,  which  are  full  twice  as  long.  It  differs  from  A.  acutifolia  in  having  the  leaves  considerably  larger, 
the  lower  part  more  suddenly  dilated,  and  the  base  not  gibbous ;  also  in  their  dark  colour  and  glossiness,  and  in  the 
more  evident  perichffitium.     It  is  easily  recognized  by  its  habit.

Slightly  differing  from  British  specimens  in  its  wider,  less  evidently  papillose  leaves,  which  are  more  suddenly 
dilated  near  the  middle.  Bridel  (Bryol.  Univ.)  cites  with  doubt,  Dillenius  (Muse.  p.  507.  t.  73.  f.  40)  as  a  synonym 
for  this  species,  but  the  description  of  Dillenius  distinctly  mentions  the  nerved  leaves  which  are  characteristic  of 
A.  Rothii,  to  which  species  even  the  description  of  Linnaeus  (as  Bridel  properly  remarks)  seems  to  refer.  The  secund 
foliage,  generally  ascribed  to  A.  rupestris,  is  not  a  constant  character,  even  in  specimens  gathered  in  the  same  locality.

those  which  are  interposed  between  the  larger  utricles,  and  which  form  the  network  of  the  leaf.  This  is  well  ex- 
plained by  the  cauline  leaves  of  Sphagnum fimbriatum  (Wils.  MSS.),  a  very  curious  British  and  Antarctic  species,  long 
confounded  with  S.  acidifolium  ;  in  them  the  spirally  lined  cells  are  altogether  absent.  Spirally  lined  cells  com- 
municate with  each  other  by  pores,  as  we  have  ourselves  witnessed  the  passage  of  animalcules  (vibrio)  from  one

In  general  aspect  exceedingly  like  the  more  compact  form  of  S.  compactiim,  Bridel,  but  preserving  the  true 
character  of  the  species  to  which  we  refer  it,  in  the  shape  of  the  leaves,  and  in  the  markings  of  the  ramuline  cellules. 
Our  specimens  are  all  fertile,  the  stems  not  two  inches  in  length.  An  example  occurs  where  two  capsules  are 
produced  upon  the  same  pseudopodium. 

Mr.  Valentine  was  the  first  to  point  out  (in  the  '  Muscologia  Nottinghamensis')  the  structure  of  the  cells  of 
the  ramuli,  which,  from  oft-repeated  observation,  we  consider  a  valid  specific  character,  distinguishing  this  species 
from  all  others.  On  the  other  hand,  the  characters  derived  from  the  length  of  the  peduncle  and  the  disposition  of 
the  branches  appear  to  be  fallacious.

Theca  matura  globosa,  pedicello  breviusculo  exserto. 

From  Sphagnum  acutifolium,  Elirh.,  this  species  may  be  readily  known  by  its  more  slender  habit,  and  is  essen- 
tially distinguished  by  the  peculiar  cauline  leaves,  which  consist  of  an  open  net-work  of  parenchymatous  cells  without 
any  intermediate  ones  lined  witli  spiral  filaments ;  the  perichsetial  leaves  are  also  very  different  in  shape,  and  those 
nf  the  branches  are  more  acute,  their  reticulation  also  is,  especially  at  the  summit,  considerably  smaller. 

The  specimens  here  described  are  not  so  slender  as  others  gathered  in  Britain  ;  but  possess  all  their  essential 
characters ;  the  S.  acii/ifolia  of  Montague  (Voy.  au  Pole  Sud,  Bot.  Crypt,  p.  2S2)  is  probably  the  same  plant.

Our  specimens,  though  not  in  the  best  state  for  the  examination  of  the  capsules,  all  possess  apparently  a  peristome 
of  eight  teeth  ;  nevertheless  we  do  not  consider  it  necessary  to  remove  this  moss  from  Splachnum.  Bridel's  genus 
Eremodon  is  not  adopted  by  Bruch  and  Schimpcr,  and  is  indeed  untenable.  Our  moss  has  characters  which  induce 
us  to  doubt  whether  it  should  be  referred  to  Tayloria  or  to  Splachnum  of  Bruch  and  Schimper.  Its  affinity  with 
the  European  Tayloria  serrata  and  Ritdolphiana  is  too  striking  to  be  overlooked ;  but  the  pale  apophysis,  though  not 
wider  than  the  capsule,  is  evidently  that  of  a  true  Splachnum  ;  while  the  peristome  connects  it  with  Dissodon,  Br. 
and  Sch.

It  will  be  seen  bow  closely  the  description  corresponds  with  that  of  O.  coarctatum,  Br.  and  Schimp.;  but  on 
comparing  authentic  specimens,  we  find  the  leaves  in  the  latter  much  wider  and  carinate,  less  dilated  at  the 
base,  more  crisped  when  dry,  the  vaginula  twice  as  long,  capsule  larger,  and  the  habit  considerably  different. 
Our  moss,  unlike  that,  has  very  little  resemblance  to  O.  crispum,  and  is  remarkable  for  its  pale  yellowish  colour  : 
it  varies  in  the  length  of  the  seta.  An  original  specimen  of  O.  coarctatum  (from  P.  de  Beauvois  in  Professor  Arnott  s

17.     TOETULA,  Hedw. 

We  retain  this  name,  instead  of  Barbula,  for  the  following  reasons  :  Sckreber  is  the  first  authority  for  the  union  of 
the  two  Hedwigian  genera  Tortula  and  Barbula  in  the  year  1791  (Gen.  Plant.)-  He  adopted  the  name  Tortula  which 
stands  first  in  Hedwig's  arrangement  for  both.     This  fact  is  overlooked  by  Bruch  and  Schimper,  who  in  their  history 


Falklands,  etc.]  FLORA  ANTARCTICA.  409 

of  this  genus  (Biyol.  Europ.),  rely  chiefly  on  the  authority  of  Bridel  in  support  of  Barhda.  But  Bridel's  authority 
is  in  favour-  of  Tortula,  for  lie  adopted  it  in  his  earlier  work.  It  was  discontinued  by  him  in  1819  (Mantissa)  under  the 
erroneous  impression  that  the  name  had  been  legitimately  given  to  a  phenogamous  genus ;  whereas  Barhda  had 
been  applied  nine  years  before  by  Loureiro  to  designate  a  Chinese  shrub.  Hence  Schrader,  Sibthorpe,  Swartz, 
Both,  and  all  British  writers  on  Mosses,  retained  Tortula,  a  name  which  would  be  at  present  unoccupied  if  not 
employed  in  conformity  with  the  views  of  Hedwig  and  Schreber.

From  all  the  European  Syntricldce  this  species  is  distinguished  by  the  serrated  leaves.  In  size  and  general 
aspect  it  is  not  unlike  Barhda  Mulleri,  Br.  and  Schimp. 

After  careful  examination  of  the  original  specimens  of  Tortula  robusta  and  T.  serrulata,  we  have  reason  to  believe 
that  one,  if  not  both,  of  these  mosses  is  the  same  species  as  our  Antarctic  plants,  differing  only  in  the  narrow  leaves ; 
but  they  are  in  too  imperfect  a  state  to  determine  very  satisfactorily.  The  figure  of  T.  robusta  represents  the  leaves 
much  too  widely  spreading,  and  they  are  also  serrulate  at  the  apex,  just  as  in  T.  serrulata.

not  uncommon,  but  rare  in  fruit. 

In  fertile  specimens  the  branches  are  arranged  at  intervals  around  a  common  axis,  the  lower  ones  usually  sub- 
divided. The  peristome  has  some  analogy  to  that  of  Lyellia,  the  teeth  being  very  small  and  the  connecting  base 
remarkably  thick  and  prominent.  The  calyptra  is  quite  glabrous.  Columella  apparently  winged.  In  habit  this 
moss  belongs  to  Pogonatum  of  Bruch  and  Schimper,  but  its  other  characters  do  not  correspond.

Although  this  moss  is  very  different  in  aspect  from  P.  dendroides,  the  characters  seem  scarcely  sufficient  to

This  differs  from  Orthodontium  lineare,  Schwaegr.  (Suppl.  1. 188),  in  the  oblong  suberect  capsule,  and  in  the 
absence  of  terminal  male  flowers,  thus  deviating  from  the  generic  character  proposed  by  Sehwaegrichen.  In  the 
inflorescence  it  agrees  with  the  British  Orthodontium  gracile,  Bruch  and  Schimper,  but  differs  in  the  form  of  the

curvati.  Folia  laxe  imbricata,  patentia,  secunda,  mollia,  ovato-lanceolata,  apiculata,  concaviuscula,  submarginata ; 
nempe  areolis  marginalibus  angustioribus,  confertis,  casteris  majuscubs,  subrhomboideis,  apice  serralata,  basi  haud 
decurrentia,  nervo  tenui  subcontinuo  instructa,  juniora  palbde  viridia,  vetustiora  luteo-viridia.  Flos  masculus  dis-

cybndracea,  paraphysibus  filiforniibus  immixta. 

Allied  to  B.  Wahlenbergii,  but  larger,  the  leaves  twice  as  long,  less  succulent,  not  decurrent  at  the  base,  mar- 
gined, apiculate,  the  nerve  extending  higher.  During  the  winter  months,  owing  to  shifting  of  the  watercourses,  the 
banks  on  which  this  moss  grows  become  inundated,  and  the  varieties  that  ensue  are  very  puzzling.  The  original 
plant  is  gradually  covered  by  a  carpet  of  young  branches  of  a  bright  green  colour,  the  whole  forming  a  soft  spongy 
and  treacherous  covering  to  the  bogs.

This  species  so  much  resembles  H.  mnioides,  as  to  be  scarcely  distinguishable  from  it  until  gathered. 

In  our  specimens  the  leaves  are  by  no  means  hilarious,  as  stated  in  the  Musci  Exotici,  and  are  compressed  only 
when  dry.  The  pericheetial  leaves  are  erect,  almost  piliferous,  and  nerved  to  the  apex  ;  young  calyptra  coriaceous,

common  on  mossy  banks  and  on  the  trunks  of  old  trees  in  the  woods  of  evergreen  beech,  abundant  in  fruit. 

Very  closely  allied  to  Hookeria  pulchella,  nobis  (part  1.  p.  142.  t.  lxii) ;  but  the  leaves  are  more  erect,  less

Our  reasons  for  not  having  previously  admitted  this  genus  will  be  found  in  the  former  portion  of  this  work. 
We  have  seen  since,  that  the  male  flowers  are  occasionally,  though  rarely,  inserted  beneath  the  accessory  leaves,  and

therefore  we  retain  this  name  for  a  genus  which  certainly  claims  to  be  separated  as  well  from  LesJcia  as  from 
Hookeria.

Under  Leskia  tamariscina  two  species  have  been  confounded  by  Hedwig  (Sp.  Muse.  p.  212).  The  name 
ought  to  be  applied  to  the  present  moss,  if  the  inconvenience  of  changing  names  generally  received  did  not  forbid.

Our  specimens  are  not  so  large  as  those  described  by  P.  de  Beauvois,  though  evidently  belonging  to  the  same 
species.  Dr.  Montague  has  properly  remarked  that  this  species  differs  from  H.  laricinum  in  the  flabelliform,  not 
pinnate,  disposition  of  its  branches,  which  all  spring  from  one  central  point  and  take  a  horizontal  direction.  Fertile 
specimens  from  Colchagua,  in  Chili,  have  also  a  more  pendulous  oblong  capsule  and  shorter  operculum.

We  owe  our  acquaintance  with  this  plant  to  the  liberality  of  our  learned  friend  M.  Montague,  who  most  gene- 
rously has  communicated  to  us  his  own  examples  of  such  Antarctic  species  as  we  desired  for  comparison  or  examination, 
unhesitatingly  confiding  his  unique  specimens  to  the  care  of  the  post-office,  that  we  might  profit  to  the  fullest 
by  his  labours,  and  avoid  unnecessary  errors.  It  differs  from  our  /.  unciformis  in  the  larger  and  narrower  leaves, 
which  are  acute  and  serrato-dentate  along  the  inner  margin.

A  very  beautifid  species,  allied  to  our  /.  diplophylla  (Pt.  1.  p.  152.  t.  64.  f.  iv)  ;  where  fructification  is  unknown, 
they  together  appear  to  form  as  natural  a  genus  as  any  which  has  been  proposed  out  of  Jungermannia,  and  differ 
from  Scapania  in  the  presence  of  stipides.  The  present  is  readily  distinguishable  from  /.  diplopliylla  by  the  separa- 
tion of  the  two  lobes  of  the  leaf,  by  their  emarginate  tips,  by  the  larger  and  closer  ciliation  of  then-  margins  and  by 
the  less  deeply  but  more  frequently  divided  and  broader  stipules.

A  very  curious  species,  and  unlike  any  with  which  we  are  acquainted.  The  habit  of  the  Falkland  Island  speci- 
mens when  dried,  is,  owing  to  their  having  grown  in  water,  so  peculiar,  that  we  regarded  them  at  first  as  a 
different  species,  which  we  described  as  /.  cavispina,  from  the  reflexed  margins  of  the  closely  imbricating  stipules, 
giving  a  grooved  appearance  to  the  back  of  the  stem.  The  calyx  is  that  of  a  LopJwcolea,  from  which  group  the 
presence  of  stipules  and  the  entire  leaves  remove  it.

This  is  one  of  the  many  southern  forms  of  Lopliocolea  nearly  related  to  one  another,  and  to  J.  bidentata  of

of  New  Zealand,  in  the  calyx  and  less  spreading  foliage ;  and  from  J.pl/ysant/ia,  nob.,  of  the  same  country,  also  by 
the  totally  different  calyx,  from  all  three  by  the  divisions  of  the  mouth  of  the  latter  organ  being  dentate.  We  are

The  largest  and  handsomest  species  of  Chiloscyphus,  in  which  the  disproportion  between  the  leaves  and  stipules 
is  very  remarkable.  The  broader  and  shorter  leaves,  their  larger  areolae  and  more  lacmiated  stipules,  are  alone 
sufficient  to  distinguish  it  from  the  former.

The  narrow  segments  of  the  differently  shaped  stipules  and  calyx  afford  the  best  means  of  distinguishing  between

large  areolae  of  the  leaves,  and  their  not  being  connate  at  the  base  with  the  stipules,  at  once  remove  the  present

divided.     The  perigonia  and  calyptra?  occupy  similar  positions  on  different  plants.

Hab.  Hermite  Island,  Cape  Horn ;  on  the  bare  ground  in  woods.  Falkland  Islands  and  Christmas

Laxe  casspitosa.  Frondes  flaecidissiuii,  2  una  longi,  erecti.  Caulis  simpliciusculus,  foliis  imbricatis  oinnino 
occlusus,  subrufescens,  gracilis.  Folia  alteima,  tenerrima,  madore  carnosiuscula,  siccitate  membranacea,  aegre  resus- 
citentia,  et  inter  se  quasi  confluentia  (hinc  irons  prima  visu  contiuua  et  lobata),  basi  latissima,  bis  latiora  quam

ovato-globosa,  irregulariter  v.  regulariter  rurnpens.  Elateres  brevissimi.  Cahjptra  irregulariter  rupta,  parte  superiore 
stylo  persistente  terrninata.  A/d/iera  ovato-oblonga?,  biseriales,  substantia  frondis  immersas,  liquido  oleaginoso 
scatentes. 

A  genus  allied  to  Fossombrouia,  but  the  structure  of  the  involucre,  apparently  formed  very  much  out  of  the 
frond  itself,  is  quite  dissimilar.  The  involucre  is  terminal  in  this  species,  but  lateral  in  a  Brazilian  congener,  which 
was  long  regarded  as  identical,  and  smooth ;  when  terminal,  winged  from  the  adhesion  to  its  surface  of  the  upper 
abbreviated  leaves  :  it  is  either  truncated  or  obscurely  two-lipped.  The  young  spores  are  united  by  fours  in  a 
transparent  membrane.  The  drawing  of  the  fruit  is  taken  from  Brazilian  specimens  of  an  allied  species,  or  perhaps 
variety,  collected  by  Mr.  Gardner  ;  the  leaves  of  the  Antarctic  plant  having  become  so  firmly  united  under  pressure, 
that  no  maceration  would  separate  them  satisfactorily. 

In  the  '  Synopsis  Hepaticarum'  of  Nees,  Lindenberg  and  Gottsche,  the  generic  name  has  been  changed  to 
Androcryphia,  with  the  following  explanation.  "  Noteroclada  nomen  Greece  cum  sonet  neque  Grseci  esse  possit 
originis,  (soil,  vwtos  tergum  non  dat  varepov,  neque  ^XaSou  sive  rami  character  hoc  loco  succurrit) ;  substituere 
aliud  nomen  a?gre  id  quidem  mecum  sustinui."  (J.  c.  p.  470.)  The  derivation  of  the  name  being,  however,  vorrfpbs 
"  madidus,"  sufficiently  vindicates  the  adoption  of  Noteroclada.

Hab.  Hermite  Island,  Cape  Horn ;  on  dead  wood  near  the  sea. 

Pileus  |-  uno.  et  ultra  latus,  tenuis,  oblique  ovatus  vel  semiorbicularis,  primum  subtiliter  pruinosus,  mox  autem

The  nearest  ally  of  this  species  is  perhaps  Ag.  mitis,  Pers.,  but  the  stem  is  not  dilated  upwards  and  the  pileus  is 
seldom  perfectly  lateral.  Its  colour,  too,  is  different,  andjt  has  not  the  same  opake  appearance  when  dry.  The 
upper  stratum  is  gelatinous,  though  the  pileus  is  dry  externally;  a  character  common  to  several  closely  allied  species. 
It  resembles  also  some  smaller  forms  of  Ag.  algidus,  Fr.,  but  that  is  at  first  resupiuate,  whereas  in  the  present  species 
the  stem  is  normal,  though,  as  in  most  of  the  smaller  excentric  Agarics,  occasionally  obsolete.  I  do  not  know  any 
other  species  with  which  it  is  necessary  to  compare  it.

This  elegant  little  Agaric  differs  from  Ag.  horkontalis,  Bull.,  an  imperfectly  known  species,  which  I  have  received 
from  Dr.  Leveille  and  have  myself  gathered  on  the  trunks  of  trees  in  the  park  at  Burleigh,  near  Stamford,  in  being 
altogether  more  delicate,  in  tlie  membranaceous  pileus,  and  especially  in  the  absence  of  smaller  gills  between  the 
larger.     The  pileus  of  Ag.  //orizontalis  also  is  much  darker  when  dry.

This  species  is  allied  to  Ag.  innocuus,  Tasch,  and  Ag.  cerodes,  Fr.  From  the  latter  it  differs  in  its  solid  stem  ; 
from  the  former,  in  its  decidedly  carnose  umbonate  pileus.

This  species  was  not  met  with  during  the  visit  of  the  Erebus  and  Terror.  Ag.  Glebarum  could  not  have  been 
considered  as  belonging  to  the  subdivision  of  Coprini.  The  pileus  is  said  by  Persoon  to  be  broader,  and  the  stem 
shorter  than  in  Bulliard's  figure.

It  is  not  possible  to  speak  very  positively  of  a  single  old  specimen  and  which  had  been  evidently  much  exposed 
to  the  weather.  It  is,  however,  certainly  neither  L.  (jemmatum,  nor  L.  pyriforme,  and  appears  to  me  to  be  a  state 
of  L.  calatum.     L.  arenarinm,  Pers.,  will  be  found  under  the  genus  Bulgaria.

A  species  which,  examined  superficially,  may  be  passed  over  as  Leptodroma  junceum,  differing  merely  in  its  more 
sinning  perithecium.  The  spores  are,  however,  of  a  very  different  form,  and  many  times  larger.  In  that  species, 
as  published  in  'British  Fungi'  (No.  197),  and  by  Madame  Libert  (No.  260),  they  are  extremely  minute  and 
obtuse  at  either  extremity ;  the  perithecium  also  is  more  closely  cellular.  In  the  specimens  published  by  Klotzsch 
and  Fries  (in  my  copy  at  least),  there  is  no  fructification.  It  resembles  also,  externally,  Leptodroma  vulgare,  but 
there  is  as  decided  a  difference  as  in  the  former  case  between  the  spores.

Not  to  be  confounded  with  Spharia punctiformis,  Pers.,  (Fr.  Sc.  Suec.  No.  56),  which  has  true  asci,  assuming 
the  production  published  by  Fries,  which  exactly  accords  with  specimens  gathered  in  Northamptonshire,  to  be 
the  type  of  the  species.  Both  Desmaziere's  (No.  984),  and  Mougeot's,  and  Nestler's  (No.  662)  plants  appear  to 
me  quite  different.  Unfortunately  in  neither  have  I  been  able  to  detect  fructification.  In  Mougeot's  plant  the 
perithecia  are  strongly  collapsed,  which  is  by  no  means  the  case  with  that  of  Fries ;  and  that  of  Desuiaziere 
approaches  Sp.  macidaformis. 

The  genus  Spharonema  is  here  considered  as  comprising  such  species  of  the  genus  Sptiaria  as  have  simple 
spores,  never  included  in  asci,  such  as  Sp.  acuta,  &c.

I  have  seen  a  single  imperfect  specimen  only,  which  is  scarcely  more  than  sufficient  to  determine  the  genus. 
I  believe  it,  however,  to  be  the  species  of  De  Candolle,  above  cited.

Allied  to  P.  scutellata  and  P.  umbrosa,  but  larger  than  either.  The  bristles  are  short  and  somewhat  flaccid, 
in  which  it  differs  strikingly  from  the  former  species,  as  also  in  its  broader  sporidia.  From  the  latter  it 
differs  principally  in  its  larger  size  and  less  conspicuous  hairs.  I  am  not  able,  in  the  absence  of  authentic  specimens, 
to  compare  the  sporidia  ;  but  if  that  species  be  the  same  with  P.  trechispora,  Berk.,  and  Broome,  which  is  not 
impossible,  the  difference  is  considerable.

Receptacula  communia  obovata,  e  disco  oblongo  corticali  enata,  |— 1  unc.  alta,  -i— |  unc.  crassa,  basi  attenuata,

linearibus  quandoque  furcatis  immixtis.     Sporidia  ignota. 

The  genus  Cyltaria  is  peculiar  to  the  Southern  hemisphere,  and  unless  Commerson's  habitat,  to  be  mentioned 
presently,  shoidd  prove  correct,  to  the  more  temperate  latitudes.  All  the  species  known  at  present  grow  on  living 
beech  ;  Cyttaria  Berteroi  on  Fagus  obliqua,  the  Fuegian  species  on  Fagus  betuloides,  that  of  Tasmania  on  Fagus  Cunn- 
inghami,  and  Cyttaria  Hooheri  on  Fagus  Antarctica.  The  species,  on  which  Cyttaria  disciformis,  Lev.,  grows,  has  not 
been  ascertained.  It  is  probable  that  the  genus  occurs  also  in  New  Zealand,  where  there  is  a  species  of  beech  closely 
allied  to  Fagus  Cunningliami.  There  exists,  indeed,  in  Monsieur  B.  Delessert's  Herbarium,  a  species  purporting  to 
have  been  collected  in  the  Isle  of  Bourbon,  by  Commerson,  but  though  the  locality*  is  veiy  precisely  indicated, 
it  is  probable,  both  on  account  of  the  difference  of  climate  and  the  absence  of  the  genus  Fagus  in  that  island,  that 
there  is  some  mistake  about  the  specimen. 

All  the  species  seem  to  grow  from  a  distinct  disc,  which  doubtless,  as  in  Podisoma,  produces  a  fresh  crop  every 
season.  The  disc  bursts  through  the  cuticle,  and  is  formed  either  entirely  of  the  lower  portion  of  the  bark,  or  of 
that  and  the  upper  stratum  of  the  wood,  which  are  split  longitudinally  or  in  the  direction  of  the  medullary  rays,  the 
fissures  being  traversed  by  loose  threads  of  mycelium.  Sometimes,  also,  there  are  traces  of  mycelium  in  portions  of 
bark  where  no  disc  has  been  protruded.  The  structure  of  the  bark  is  often  much  deranged,  and  sometimes  quite 
disorganized.  The  base  of  the  receptacles  is  attenuated,  and  penetrates  generally  to  the  dotted  vessels.  In  Cyttaria 
Qimnii,  which  seems  more  truly  cortical,  there  appears  always  to  be  a  fascicle  of  such  vessels  in  connexion  with  the 
base  penetrating  through  the  cortical  stratum.  I  do  not  find  this  to  be  the  case  in  Cyttaria  Hookeri.  The  structure 
of  the  substance  of  the  receptacles  is  so  different  in  the  plant  when  dry,  from  that  in  the  same  species  when 

*  The  label  attached  to  the  specimen  is  literally  as  follows  : —

preserved  in  spirits,  as  to  be  scarcely  recognizable.  I  had,  at  first,  on  examining  dried  specimens  of  Gyttaria 
Gunnii,  fancied  that  I  had  made  some  mistake  in  the  analysis  given  in  my  paper  in  the  19th  volume  of  the  Linuean 
Transactions.  The  fact  is,  that  when  a  very  thin  slice  of  the  dried  plant  is  placed  on  the  field  of  the  microscope,  the 
gelatinous  coat  of  the  threads  of  which  it  is  composed  becomes  visible  ;  while  in  the  plant  preserved  in  spirits,  the 
jelly  seems  to  form  one  common  mass  in  which  the  central  tube  alone  is  exhibited,  and  when  the  plexus  of  filaments 
is  drawn  out  with  the  point  of  a  lancet,  they  appear  far  less  curled  than  they  do  in  situ.  Perfect  sporidia  have  not 
at  present  been  observed  in  any  species.*

I  have  not  detected  fructification  ;  but  the  species  certainly  belongs  to  the  genus  Asterina,  which  is  very  properly 
separated  from  Botlddea  by  Leveille.  The  cells  of  which  the  perithecimn  is  composed  are  elongated,  but  very  irre- 
gular, and  I  find  similar  cells  often  filling  up  the  interstices  left  by  the  crossing  of  the  radiating  threads.  Sometimes 
the  mycelium  is  very  obscure  and  the  species  then  assumes  quite  a  different  appearance,  the  fructifying  cells  pre- 
dominating and  the  patches  presenting  merely  a  brown  stain  studded  with  darker  specks.

Apparently  different  from  A.  Azara,  Lev.,  in  its  perithecia,  which  are  not  depressed  in  the  centre,  as  in  that

The  sporangia  in  the  specimens  before  me,  which  are  very  scanty,  are  almost  destitute  of  flocci,  but  accompanied 
by  an  abundant  tawny  mycelium,  thus  confirming  the  opinion  of  Fries  and  Corda,  that  Eurotium  epixylon  is  not 
really  a  distinct  species.  I  cannot,  however,  think  with  Corda  that  it  has  the  slightest  affinity  with  Pliysannn. 
The  morphosis  has  not  at  present  been  traced,  and  till  this  is  done  it  appears  better  to  let  it  remain  where  Fries  has 
placed  it,  in  the  neighbourhood  of  Mucor. 

•  The  peridium  is  lined  with  a  stratum  of  gelatinous  cells,  which  vanish  in  a  great  measure  as  the  plant  approaches 
maturity.  The  flocci  in  Kze.  and  Schin.,  n.  83,  are  rough  and  dark,  but  I  find  great  variation  both  of  surface  and 
colour.

Hab.  Tierra  del  Fuego,  the  Falkland  Islands,  and  Kerguelen's  Land ;  very  abundant  at  half-tide  mark 
and  below  it ;  also  in  the  open  ocean,  between  lat.  45°  and  55°  S.,  reaching  the  65th  degree  of  south  latitude 
in  the  meridian  of  New  Zealand. 

This,  the  Lessonia,  and  Maerocystis  are  the  three  most  remarkable  Alga  of  the  Antarctic  regions,  especially  on 
account  of  their  size ;  the  present  exceeding  any  sea-weed,  except  the  Lessonia  and  the  Ecklonia  buccinalis  of  the 
Cape  of  Good  Hope,  in  bulk ;  while  the  Maerocystis,  to  which  we  shall  afterwards  allude,  is  the  longest  vegetable 
production  known. 

The  nearest  affinity  of  D' Urvillaa  was  considered,  in  the  '  London  Journal  of  Botauy'  (vol.  ii.  p.  325),  to  be 
with  Himanthalia  of  the  Northern  and  Arctic  seas,  an  opinion  to  which  one  of  us  was  led  by  observing  how,  in  habit 
and  locality,  these  species  represented  each  other  in  the  opposite  Polar  oceans.  Wahlenberg,  Bory  de  St.  Vincent  and 
Greville,  all  regard  the  curious  pezizsefomi  organ  of  Himanthalia  as  the  frond,  and  the  deciduous  strap-shaped 
lacimse  as  receptacles,  which  view  is  also  maintained  in  the  '  Phycologia  Britannica'  (t.  lxxviii.)  Lyngbye  (the  founder 
of  the  species)  and  Agardh,  on  the  other  hand,  pronounce  the  frond  to  be  swollen  at  the  base  into  a  bladdery  stipes, 
furnished  with  strap-shaped  laciniae,  over  whose  surface  the  conceptacles  are  scattered  as  in  D'  Urvillaa  ;  and  in 
Xiphophora,  a  genus  (as  pointed  out  by  Montague)  nearly  allied  to  the  present,  and  which  represents  it  in  a  lower 
latitude  of  the  Southern  Ocean.  In  the  '  London  Journal  of  Botany'  the  true  analogy  to  the  bladder  of  Himanthalia 
was  sought  in  the  trumpet-shaped  stipes  of  Ecklonia  buccinalis,  but  in  that  plant  the  growth  of  stipes  and  frond 
proceeds  from  the  earliest  stage,  pari-passu,  whilst  the  bladder  of  Himanthalia  is  fully  developed  before  the  straps 
appear. 

We  have  nowhere  seen  a  good  representation  of  the  beautiful  cellular  tissue  of  D'  Urvillaa  utilis,  which,  in 
its  fresh  state,  is  so  regular  and  large  as  to  resemble  perfectly  in  size  and  structure  one  of  the  two  layers  of  cells 
found  in  honey-comb.  Most  of  the  specimens  brought  to  Europe  are  injured  by  pressure,  which  can  however 
hardly  have  caused  the  total  obliteration  of  structure  which  M.  Bory's  plate  represents  ;  the  most  accurate  figure  we 
know  is  given  in  the  beautiful  plate  accompanying  M.  Decaisne's  '  Essay  on  the  fructification  of  Algae' . 

The  spores  of  this  and  the  following  species  are  divided  into  four,  and  we  cannot  doubt  but  that  this  divi  sion 
is  followed  by  the  complete  breaking  up  of  the  organ  into  four  sporules,  whose  future  germination  resembles  that 
described  by  MM.  Decaisne  and  Thuret  in  Fucus  serratus  ('Annales  des  Sc.  Nat. '  Ser.  3.  vol.  iii.  p.  10.  t.  2).  The 
conceptacles  contain  probably  both  antheridia  and  spores,  so  far  as  we  can  judge  from  drawings  taken  from  the  bving 
plant,  though  at  the  time  these  bodies  were  not  recognized  as  belonging  to  two  differents  classes  of  organs. 

The  northern  limit  of  D 'Urvillaa  will  probably  be  found  to  be  the  latitude  of  Valparaiso,  or  33°  S.,  on  the 
West  coast  of  South  America,  and  50°  S.,  on  the  opposite  shores  of  the  same  continent.  In  New  Zealand  it  attains 
the  parallel  of  40°,  but  whether  it  inhabits  any  of  the  shores  of  Tasmania,  or  is  there  represented  by  the  Fucus 
potatorum,  is  a  question  we  cannot  answer.  Though  carried  by  the  currents  along  the  ocean  to  the  south  of  the 
Cape  of  Good  Hope,  (for  it  was  collected  in  that  meridian  in  the  51st  degree,  floating  in  the  open  ocean,)  it  does 
not  appear  to  inhabit  or  be  cast  upon  the  southern  extremity  of  Africa ;  and  in  the  Indian  Ocean,  again,  its  range  is 
not  likely  to  be  north  of  the  Islets  of  Prince  Edward's,  the  Crozet  group  and  Kerguelen's  Land.  On  the  other  hand, 
the  south  latitude  it  attains  is  probably  regulated  by  the  position  of  the  Pack  Ice,  to  within  a  few  miles  of  which 
it  was  traced  by  the  Antarctic  Expedition,  on  one  occasion,  south  of  New  Zealand  to  the  65th  degree,  which  is 
probably  its  "ultima  Thule  "  in  any  longitude;  for  it  was  there  the  last  trace  of  vegetation.  It  grows  invariably 
accompanied  by  the  Maerocystis  pyrifera. 

Bory  de  St.  Vincent  states,  on  the  excellent  authority  of  D'Urville,  that  the  poorer  classes  of  West  Chili  use 
this  plant  for  food,  and  that  when  made  into  soup  it  is  very  palateable,  being  sweet  and  mucilaginous.  In  Kerguelen's 
Land  its  enormous  and  weighty  fronds,  sometimes  ten  feet  long,  and  almost  too  heavy  for  a  man  to  lift,  form  the 
only  shelter  for  the  shells  and  soft  animals,  which  there  find  a  refuge  from  the  flocks  of  aquatic  birds  that  cover  the 
shores  and  follow  the  receding  tide.

Always  considerably  smaller  than  the  B.  idilis,  of  a  much  thinner  texture,  and  readily  distinguishable  by  its 
fibrous  root.  I  have  never  observed  the  frond  of  even  the  largest  state  of  this  species  to  be  filled  with  those 
elongated  transverse  cells  which  distinguish  the  former. 

The  structure  of  the  fronds  is  seen  to  consist,  on  a  transverse  section,  of  a  dense  narrow  layer  of  cortical  sub- 
stance, which  gradually  becomes  more  open  inwards,  and  there  breaks  up  into  parallel  lanielke  projecthig  towards  the 
centre  of  the  frond.  These  are  less  densely  packed  inwards,  and  are  united  at  right  angles  by  similar  very- 
short  plates,  together  forming  a  loose  cellular  tissue,  whose  walls  are  thickened  at  the  angles ;  which,  again,  at  the 
very  centre  of  the  frond,  are  gradually  resolved  into  a  mass  of  slender,  short,  waved  filaments,  free  or  anastomosing 
and  floating  in  a  gelatine. 

The  affinity  of  the  Laminaria  potatorum  is  probably  with  this  genus ;  it  is  described,  by  M.  Kutzing,  under  the 
generic  name  of  Sarcophycus  (Phycologia,  p.  392).  I  have  examined  a  very  small  fragment  of  the  plant,  and  find 
the  spores  to  be  contained  in  cysts,  altogether  like  those  of  D'  Urvillaa  and  Xipltopliora.

Hab.  Graham's  Land;  lat.  63°  S.,  floating  in  the  ocean,  I)r.  Lyall.  Deception  Island,  New  South 
Shetlands;  Mr.  Webster. 

An  accurate  description  of  this  noble  sea-weed  is  given  by  its  discoverer,  Mr.  Webster,  R.N.,  in  the  Appendix  to 
the  Narrative  of  Capt.  Foster's  Voyage  ;  though  nothing  was  known  of  the  species,  botanically,  untd  specimens  were 
received  by  Dr.  Montagne,  from  the  Herbarium  of  the  French  South  Polar  Expedition,  collected  within  a  very  few  miles 
of  the  spot  where  it  was  again  seen  by  the  Antarctic  Expedition,  and  obtained  by  our  indefatigable  friend,  Dr.  Lyall. 

The  existence  of  this  sea-weed  on  the  Icy  shores  of  an  Antarctic  land,  in  the  longitude  of  Cape  Horn,  is  a  most 
singular  and  anomalous  fact ;  for  I  bebeve  it  to  be  the  only  species  of  the  tribe  Cystosdrete,  which  inhabits  the  colder 
or  Antarctic  seas  of  South  America  ;  though  many  abound  in  similar  temperate  latitudes  of  New  Zealand,  Lord 
Auckland's  group,  New  Holland,  and  Tasmania.  We  have  thus,  under  the  most  rigorous  skies,  the  representative  of 
a  group,  the  total  absence  of  whose  other  species  in  warmer  seas  of  the  same  longitude,  was  supposed  to  be  owing 
to  a  low  degree  of  temperatine  being  destructive  to  its  life.  The  said  group  of  Cystoselrece  is  not  here  represented  by  a 
species  in  any  way  indicative  of  its  habitat  being  far  removed  from  its  congeners,  or  of  its  locabty  being  uncongenial,

except  by  one  of  its  own  aspect ;  for  its  nearest  and,  indeed,  very  near  ally,  is  a  native  of  New  Holland ;  whilst  in 
size,  luxuriance  and  beauty  of  growth,  the  present  surpasses  not  oidy  all  other  species  of  the  genus,  but  almost  the 
whole  of  the  group  Cystoseirea. 

We  are  accustomed  to  regard  the  ocean  as  so  ever-active  and  powerful  au  agent  in  facilitating  migration,  and 
its  uniform  temperature  is  so  conducive  to  the  general  diffusion  of  species,  that  it  seems  almost  wonderful  that  Alga 
should  have  limits  to  their  distribution,  especially  in  waters  which  gird  the  globe  on  the  same  parallel  of  latitude, 
and  whose  unchecked  swells  and  currents  literally  extend  over  every  degree  of  longitude.  The  remarkable  increase  in 
temperature  of  the  tropical  over  the  polar  seas  of  the  Atlantic  may,  and  probably  alone  does,  check  the  progress  of 
the  Macrocystis  in  its  course  from  Cape  Horn  to  the  Equator  in  that  ocean,  for,  as  I  shall  afterwards  show,  the  same 
sea-weed  can  float  with  the  colder  currents  of  the  Pacific  from  the  same  Cape  to  Behriug's  Straits ;  but  no  such 
obstacle  prevents  the  fullest  interchange  of  Cystoseirea  between  New  Zealand  and  the  temperate  seas  of  South 
America.  It,  however,  is  the  fact,  that  whilst  this  group  literally  abounds  in  certain  latitudes  and  longitudes, 
which  are  those  of  New  Holland  and  the  West  Pacific,  they  are  nearly  absent  from  analogous  positions  in  the 
longitude  of  South  America. 

Throughout  all  latitudes  the  two  tribes  Fucoidea  and  Cystoseirea  form  that  prevailing  marine  vegetation  to  which 
the  name  sea-weed  is  commoidy  appKed  ;  and  the  different  genera  so  far  arrange  themselves  within  geographical  limits 
as  to  present,  with  such  few  exceptions  as  the  Scytothalia  Jacauinotii,  a  most  harmonious  assemblage.  Thus, 
in  the  opposite  colder  and  frigid  zones  the  waters  are  inhabited  by  certain  genera  of  Fucoidea  which  are  in  a  great 
measure  representatives  of  one  another  ;  as,  in 


.  ,        ,    Fucus  proper,  and  "1    are  represented  in  analogous  1      B'Urvillea, 

Himanthalia,  southern  zones,  by  J    SarcopJ/ycus, 


and 
Kiitz. 


None  of  these  genera  approach  the  tropics,  for  the  Fucoidea  abound  towards  the  poles,  and  there  attain  their  greatest 
bulk,  diminishing  rapidly  towards  the  Equator,  and  ceasing  some  degrees  from  the  Line  itself.  The  representatives 
of  the  Cystoseirea  in  the  higher  latitudes  of  the  opposite  hemisphere,  are  equally  appropriate  with  those  of 
Fucoidea,  for  we  have  in 

f  Cystoseira,  and  "|     represented  in  the     f  Blossevillea,  and 
Halidrys,        [    south  cool  zone,  by  1      Scytothalia  • 

whilst  the  immense  genus  Sargassum  finds  its  maximum  in  lower  latitudes,  and  under  the  Equator  itself. 

Such  are  the  salient  featm-es  of  the  distribution  of  these  tribes,  which  are  not  influenced  by  the  minor  divisions, 
chiefly  local  assemblages  of  small  genera,  affecting  exclusively  certain  coasts  or  bays.

The  fructification  of  the  species  of  Lessonia  occurs,  as  in  Macrocystis,  upon  the  surface  of  the  fronds,  and 
there  forms  large  patches.  In  the  present  species  the  sori  are  situated  beyond  the  middle  of  the  leaf,  they 
are  oblong  and  nearly  as  broad  as  the  lamina,  of  which  they  carry  away  the  upper  part  when  decaying,  causing 
their  broad  apices  to  be  two-horned.  In  none  of  our  specimens  is  the  point  perfect,  all  the  spores  we  have  seen 
being  situated  on  the  edges  of  the  sorus,  which  has  itself  fallen  away  from  the  frond.  The  air-cells  are  less 
numerous,  and  the  spores  are  smaller,  shorter,  more  densely  packed  than  in  the  following  species,  and  covered

458  FLORA    ANTAHCTICA.  Fuegia,  the 

with  a  very  thin  cuticular  layer  of  the  frond.  The  presence  of  this  cuticle  is  owing  to  the  peculiar  manner 
in  wliich  the  superficial  or  sporiferous  cells  of  the  frond  dehisce  transversely,  allowing  the  dispersion  of  the  spores 
(shown  in  the  dissection  of  Macrocyst'is,  given  at  Plate  CLXIX.,  CLXX.  Fig.  2). 

This  and  the  following  are  truly  wonderful  Alga,  whether  seen  in  the  water  or  on  the  beach ;  for  they  are 
arborescent,  dichotomously  branched  trees,  with  the  branches  pendulous  and  again  divided  into  sprays,  from  which 
hang  linear  leaves  1-3  feet  long.  The  trunks  usually  are  about  5-10  feet  long,  as  thick  as  the  human  thigh, 
rather  contracted  at  the  very  base,  and  again  diminishing  upwards.  The  individual  plants  are  attached  in  groups 
or  solitary,  but  gregarious,  like  the  pine  or  oak,  extending  over  a  considerable  surface,  so  as  to  form  a  miniature 
forest,  which  is  entirely  submerged  during  high-water  or  even  half-tide,  but  whose  topmost  branches  project  above 
the  surface  at  the  ebb.  To  sail  in  a  boat  over  these  groves  on  a  calm  day  affords  the  naturalist  a  delightful  recreation  ; 
for  he  may  there  witness,  in  the  Antarctic  regions,  and  below  the  surface  of  the  ocean,  as  busy  a  scene  as  is  presented 
by  the  coral  reefs  of  the  tropics.  The  leaves  of  the  Lessonia  are  crowded  with  Sertulariee  and  Mollusca,  or  encrusted 
with  Flustra ;  on  the  trunks  parasitic  Alga  abound,  together  with  Chitons,  Patella,  and  other  shells ;  at  the  bases, 
and  amongst  the  tangled  roots  swarm  thousands  of  Crustacea  and  Radiata,  whilst  fish  of  several  species  dart  amongst 
the  leaves  and  branches.  But  it  is  on  the  sunken  rocks  of  the  outer  coasts  that  this  genus  chiefly  prevails,  and  from 
thence  thousands  of  these  trees  are  flung  ashore  by  the  waves,  and  with  the  Macrocystis,  and  I)'  TJrvillea,  form 
along  the  beach  continued  masses  of  vegetable  rejectamenta,  miles  in  extent,  some  yards  broad,  and  three  feet  in 
depth ;  the  upper  edge  of  this  belt  of  putrefying  matter  is  well  in-shore,  whilst  the  outer  or  seaward  edge  dips  into 
the  water,  and  receives  the  accumulating  wreck  from  the  sub-marine  forests  throughout  its  whole  length.  Amongst 
these  masses  the  best  Alga  of  the  Falklands  are  found,  though  if  the  weather  be  mild,  the  stench,  wliich  resembles 
putrid  cabbage,  is  so  strong  as  to  be  almost  insufferable.  The  ignorant  observer  at  once  takes  the  trunks  of  Lessonia 
thus  washed  up  for  pieces  of  drift-wood,  and  on  one  occasion,  no  persuasion  coidd  prevent  the  captain  of  a  brig  from 
employing  his  boat  and  boat's  crew,  during  two  bitterly  cold  days,  in  collecting  this  incombustible  weed  for  fuel ! 

The  trunks,  which  contract  to  one-fourth  of  their  original  dimensions  when  dry,  and  become  deeply  furrowed, 
are  perfectly  smooth  and  cartilaginous  when  fresh.  On  being  cut  across,  the  curious  appearance  of  concentric 
elliptical  rings,  in  many  respects  similar  to,  though  very  different  from,  those  of  an  Exogenous  trunk,  is  very  evident. 
These  rings  surround  a  lance-shaped  pale  line,  which  occupies  the  broad  axis  of  the  compressed  stem,  without  reaching 
across  it,  and  appears  to  afford  some  rude  indication  of  the  age  of  the  plant,  though  of  this  we  could  by  no 
means  satisfy  ourselves.  It  is  singular  that  this,  the  most  arborescent  of  the  Alga,  and  the  beautiful  Usnea 
melaxantlia,  the  most  tree-like  in  form  of  the  Lichens,  are  nearly  the  only  plants  of  the  Orders  to  which  they 
respectively  belong,  conspicuously  presenting  even  a  semblance,  if  it  be  no  more,  to  a  growth  that  indicates  an 
increase  by  periodical  accessions  to  the  circumference. 

The  substance  of  the  trunk  of  the  Lessonia  is  very  usefully  employed  by  the  Gauchoes,  for  knife-handles*; 
the  haft  of  the  instrument  is  plunged  into  a  rudely-shaped  piece  of  this  weed,  wliich  contracts  into  a  substance 
harder  than  horn.  The  range  of  the  present  species  is  from  the  Falkland  Islands  to  Cape  Horn,  and  thence 
north  along  the  coasts  of  South  America  probably  to  Valparaiso.

Fructification  forming  a  large  oblong  or  linear  sorus  between  the  base  and  middle  of  the  frond,  of  a  rich 
red-brown  colour  when  held  between  the  eye  and  light,  imbedded  in  the  thickened  substance  of  the  frond,  which 
decays  with  it.  On  a  transverse  section  the  soriferous  lamina  is  seen  to  be  hollow  in  the  centre ;  or  rather  the 
sorus  is  formed  of  two  parallel  plates,  each  covered  externally  with  densely  aggregated  spores,  which  occupy  what 
are  the  superficial  cells  of  other  parts  of  the  frond.  Below  the  superficial  series  of  cells,  and  especially  in  fertile 
specimens  beneath  the  spores,  are  several,  4-6  or  many  more,  air-cavities,  reposing  on,  and  separated  from  each  other 
by  a  loose  cellular  tissue,  which  is  hexagonal,  transparent,  the  cells  becoming  transversely  elongated  and  finally 
towards  the  centre  of  the  frond  breaking  up  into  a  layer  of  matted  filaments,  which  surrounds  the  cavity,  a 
structure  resembling  very  closely  that  of  Fucus  confiuens  as  given  by  Turner.  When  thy,  the  surface  of  the  plant  is 
covered  with  white  efflorescence,  similar  to  that  of  Laminaria  saccharina,  it  has  been  analysed  by  my  friend 
Mr.  Stenhouse  of  Glasgow,  who  finds  it  to  contain  excellent  Manna,  and  who  further  informs  me  that  this  and 
the  other  larger  Antarctic  Alga  are  peculiarly  rich  in  Iodine. 

The  Lessonia  quercifolia  of  Bory,  is  described  and  figured  as  having  the  frond  covered  with  cavities  containing 
spores,  whence  it  woidd  appear  to  belong  to  Fucoidea,  and  to  be  more  allied  to  Z>'  Urvillea  than  to  this  genus. 

Lessonia  ciliata  of  Postel  and  Rupprecht,  is  certainly  only  the  young  state  of  Macrocystis  pyrifera.

Certainly  very  near  L.  fuscescens ;  but  as  far  as  could  be  judged  on  examining  the  plant,  both  on  the  shores  it 
inhabits  and  in  the  herbarium,  it  has  good  claims  to  be  considered  a  distinct  species,  especially  in  the  many  short 
stipites,  short  branches  and  broad  leaves.  Never  having  seen  the  fruit,  however,  it  may  prove  the  young  of 
L.  fuscescens,  for  we  can  well  suppose  only  one  out  of  the  many  stems  of  that  plant  to  attain  any  great  dimensions, 
and  the  lamina  of  the  young  state  to  be  broader  than  that  of  the  adult. 

The  ramification  of  all  the  species  of  Lessonia  is  dichotomous ;  each  plant  in  a  young  state  consists  of  a  few 
rooting  and  clasping  fibres,  giving  off  a  single  stem  (or  petiole)  and  frond.  This  frond  splits  at  the  base,  and  as 
the  growth  proceeds,  the  fissure  extends  vertically  upwards,  till  the  original  frond  is  bisected  ;  each  of  the  two 
parts  is  now  a  complete  frond,  altogether  similar  to  the  primary  one,  and  provided  with  a  petiole  of  its  own  :  these 
again  divide,  and  the  process  is  repeated.  Hence  the  rapid  growth  of  this  genus,  and  hence  the  origin  of  the 
flattened  form  of  ramidi  and  elliptic  core  which  is  placed  in  the  long  axis  of  these  rarnuli  and  across  the  axis  of  the 
terete  stem.  It  was  not  observed,  whether  any  relation  existed  between  the  number  of  branches  on  the  whole  frond 
and  of  concentric  rings  in  the  trunk.  The  latter  are  probably  the  indices  of  the  number  of  times  that  a  subdivision 
of  the  laminae  has  occurred,  supposing  that  all  split  at  about  the  same  epoch,  rather  than  a  register  of  the  years 
the  vegetable  has  existed ;  as  the  following  account  of  the  anatomy  of  this  species  will  show. 

A  branched  portion  of  the  plant,  terminated  by  four  laminae,  necessarily  presents  subdivisions  of  three  periods 
of  growth  :  1st,  the  petioles  of  the  four  laminae ;  2nd,  the  two  rarnuli  from  which  the  four  are  given  off;  and  3rd, 
the  one  branch  which  gives  off  the  two  latter :  these  were  successively  examined. 

1 .  The  base  of  the  lamina  or  petiole  is  exceedingly  compressed,  and  composed  of  a  mass  of  cellular  tissue  of 


4fi0  FLORA    ANTARCTICA.  [Fuegia,  the 

different  textures,  all,  however,  very  gelatinous,  and  modifications  of  the  three  layers  forming  the  leaf,  there  are 
1st,  the  superficial  tissue  (or  cortex)  consisting  of  small  cells,  closely  packed  and  full  of  chromule,  gradually  opening 
out  into,  2nd,  an  intermediate  tissue  of  much  larger  cells  more  loosely  placed,  with  little  or  no  contained  chromule, 
separated  by  much  gelatine  ;  and  3rd,  an  elliptical  core  placed  in  the  long  axis  of  the  petiole,  composed  of  still  smaller 
cells,  separated  by  broader  masses  of  gelatine,  which  latter  is  permeated  by  canals,  full,  as  are  the  small  cells,  of 
chromide. 

2.  Each  ramulus,  from  which  proceed  the  two  petioles,  whose  structure  we  have  just  described,  presents  no  very 
important  difference  from  them ;  the  core  no  longer  stretches  across  it,  however,  but  the  whole  petiole  within  the 
superficial  portion  is  augmented  by  a  newly  developed  though  indistinct  zone  of  cellular  tissue,  thus  deposited  between 
the  superficial  (or  cortical)  and  intermediate  tissue.  At  this  period  the  cortex  is  somewhat  broader,  and  the 
intermediate  tissue  has  become,  through  the  absorption  of  the  gelatine,  much  more  conspicuous  ;  the  cells  being 
larger  and  the  spaces  between  them  narrower ;  little  or  no  change  is  perceptible  in  the  core  itself. 

3.  The  branch  is  very  materially  different  from  either  of  the  above,  for  what  was  hitherto  the  petiole  is  now 
enclosed  (all  but  its  cortex)  in  a  very  broad  zone  of  cellular  tissue,  whose  cells  are  large  and  thin  towards  the 
old  tissue,  elongated  and  of  a  different  shape,  so  as  to  show  the  line  of  separation  between  the  two  periods 
of  growth  (see  B  1,  of  the  plate  Lessonia). 

From  this  time  forward  the  normal  mode  of  growth  followed  by  the  stem  exhibits  an  additional  layer  or 
zone  of  cellular  tissue  for  every  subdivison  of  the  frond,  (shown  at  A  1,  where  six  are  interposed  between 
the  cortex  and  core).  It  is  not  probable,  however,  that  this  numerical  relation  can  be  always  evident,  or  that 
the  number  of  subdivisions  of  the  frond  will  indicate  the  rings  of  growth  in  a  large  stem.  This  uncertainty 
arises  from  the  branches  being  frequently  broken  off ;  added  to  which,  the  growth  of  the  sea-weed  is  very  rapid, 
and  there  being  no  period  of  rest,  irregular  zones  may  be  expected,  or  their  absence  from  those  branches  of  the  plant 
whose  leaves  are  injured. 

In  their  anatomy  the  stems  of  L.fuscescens  and  L.  nigrescent  do  not  differ  much  from  that  of  this  species, 
except  that  the  air-cells  are  copious  in  the  stems  of  the  former,  and  much  rarer  in  the  latter ;  in  which  also 
the  cortical  substance  is  much  broader. 

In  the  elegant  Lessonia  Sinclairi,  Harv.  MSS.,  from  California,  the  stipes  (which  bears  but  a  solitary  linear 
frond)  is  terete,  and  in  the  specimen  we  examined,  contains  a  central  core,  reaching  half-way  across  the  diameter. 
There  are  apparently  two  rings  of  tissue  beneath  the  cortex,  separated  by  a  zone  of  very  large  cells  (air-cells  ?) ; 
whence  it  is  difficult  to  account  for  the  stem  being  terete,  for  the  frond  is  plane,  and  the  core  three  times  longer 
than  broad.  Nor  is  it  easy  to  explain  the  origin  of  the  two  zones  surrounding  the  core  ;  if  they  really  be  succes- 
sively deposited,  it  is  possible  that  the  frond  is  two  years  old ;  if  not,  that  the  large  cells  are  air-cells,  and  do  not 
indicate  a  line  of  separation  between  two  successive  deposits. 

I  have  stated  the  growth  of  the  Lessonia  to  be  very  rapid ;  this  is  proved  by  the  zones  of  a  five-ringed  stem 
being  progressively  broader  towards  the  circumference.  The  probability,  too,  of  one  being  added  for  every  time  the 
laminae  divide,  and  the  fact  that  the  process  of  subdivision  is  continued  in  geometrical  progression,  all  favour  the 
opinion  that  these  Algce  attain  their  enormous  bulk  in  a  very  few  mouths.  The  vast  masses  washed  up  on  the  outer 
eastern  shores  of  the  East  Falkland  Island,  and  the  rapidity  with  which  they  decay,  are  additional  proofs  of  a  singularly 
rapid  development. 

The  analogy  between  the  mode  of  growth  exhibited  by  this  genus  and  an  Exogenous  tree,  is,  though  incomplete, 
very  obvious ;  both  increase  by  layers  deposited  outside  one  another,  within  a  cortical  substance,  and  both  con- 
tain an  axis  of  tissue  different  from  that  forming  the  greater  part  of  the  trunk  :  here,  however,  there  are  no 
traces  of  medullary  rays.  We  conclude  this  subject  with  the  observation,  that  the  periodical  increment  of  the 
trunk  being  dependent  on,  or  coincident  with,  the  formation  of  the  laminae,  these  appear  to  perform  the  office  of  the 
leaves  in  the  higher  order  of  plants  ;  and  that  the  Lessonia  is  also  in  this  respect  analogous  to  an  Exogenous  plant,

deprived  of  its  woody  tissue,  for  it  is  a  stem  composed  of  layer  upon  layer  of  cellular  tissue,  deposited  round  an  axis, 
which,  like  the  pith,  when  once  formed,  is  afterwards  but  slightly  modified.

Hab.  Throughout  the  Antarctic  seas,  between  the  parallels  of  40°  and  64°,  both  attached,  and  floating 
over  the  whole  ocean. 

After  a  very  attentive  examination  of  many  hundreds  of  specimens,  we  have  arrived  at  the  conclusion  that  all 
the  described  species  of  this  genus  which  have  come  under  our  notice  may  safely  be  referred  to  Macrocystis 
pyrifera.  Nor  can  these  variations  excite  surprize,  when  it  is  considered  that  this  gigantic  weed  is  subject  to  every 
vicissitude  of  climate,  of  temperature,  and  exposure ;  that  it  literally  ranges  from  the  Antarctic  to  the  Arctic  circle, 
through  120  degrees  of  latitude ;  that  it  lives  and  flourishes,  whether  floating  or  attached,  growing  in  bays,  harbours, 
or  the  open  sea  when  most  distant  from  land ;  and,  lastly,  that  it  equally  adapts  itself  to  the  calmest  or  most 
tempestuous  situations,  to  waters  of  uniform  depths  or  those  which  rise  and  sink  with  the  tide,  to  dead  water  or  to 
strong  currents.  One  thing  alone  it  requires,  and  that  is,  a  mean  depth  of  six  or  more  fathoms ;  for,  like  the  Lamina- 
rim  of  our  own  shores,  it,  and  others  of  the  same  tribe  in  the  south,  invariably  form  the  outer  belt  of  marine  vegetation. 

A  few  remarks  upon  the  above  varieties  may  be  interesting ;  showing  how  much  their  characters  depend  upon 
natural  causes,  and  how  much  more  upon  mutilations  of  the  specimens,  or  changes  during  the  operation  of  drying. 

Variety  (3.  integrifrons.  This'  we  have  received  from  various  parts  of  the  west  coast  of  South  America ;  its 
characters  rest  almost  entirely  on  the  want  of  ciliation  at  the  margin  of  the  frond,  which  is  much  dependent  upon  the 
portion  of  the  plant  from  which  the  specimen  is  taken,  the  lower  leaves  being  always  nearly  entire ;  also  on  the 
state  of  the  waters,  those  plants  which  grow  in  quiet  bays  having  very  much  developed  cilia?,  whilst  those  from  the 
main  ocean  or  stormy  coasts  are  generally  more  entire. 

Variety  S.  zosterafolia,  is  a  plane  and  narrow-leaved  state  of  M.  pyrifera  ;  we  have  traced  all  the  changes  in 
one  specimen  of  M.pyrifera,  from  very  rugose  to  perfectly  plane.    Young  specimens  and  terminal  leaves  are  generally

plane,  and  it  often  depends  on  the  smoothness  of  the  water  how  long  they  may  remain  so.    This  variety  is  abundant 
everywhere  in  the  Antarctic  seas. 

Variety  y.  angustifrons.  The  character,  drawn  from  the  tenuity  of  the  vesicles,  is  utterly  unsatisfactory,  being 
attributable  to  the  drying  of  the  specimen,  and  the  locality  of  the  live  plant.  Besides  the  Antarctic  habitats  of 
this  variety,  it  has  been  found  in  Chili,  New  Zealand,  and  the  Indian  Ocean. 

Varieties  e.  luxurians,  and  (.  membranacea.  If  any  form  of  this  genus  deserves  specific  distinction  it  is  surely 
the  noble  one  we  have  designated  c .  luxurious ;  and  yet  permanent  characters,  distinguishing  it  from  pyrifera,  were 
vainly  sought  in  plants  gathered  on  the  shores  of  Berkeley  Sound.  Both  there  and  at  Cape  Horn  these  two  states 
inhabited  deep  and  still  waters,  where,  as  might  be  expected,  the  Macrocystis  would  acquire  its  greatest  develop- 
ment, where  its  substance  would  be  most  membranous,  its  stems  most  slender,  and  the  vesicles  broad  with  thin  walls, 
and  the  base  of  the  frond  broadest.  We  have  seen  no  specimens  of  these  varieties  except  what  were  brought  home 
by  the  Antarctic  Expedition. 

Variety  rj.  HumbolcUii,  at  first  sight  appears  different,  and  the  specimens  found  on  the  outer  shores  of  the 
Ealklands  we  once  thought  might  belong  to  a  distinct  species.  The  rounded  form  of  the  vesicles,  however,  which 
affords  the  main  character,  is  not  constant  on  specimens  collected  in  the  Coral  Islands  by  Captain  Beechey.  It 
has  been  gathered  at  various  places  along  the  west  coast  of  South  America,  from  Cape  Horn  to  the  Equator,  and 
far  westward  in  the  Pacific  amongst  the  Coral  Islands. 

With  regard  to  other  states,  which  we  have  not  seen,  the  most  remarkable  is  the  M.  Orbignyana  of  Montagne 
(Sert.  Patagon.  p.  12.  t.  1.),  which  has  the  vesicles  remarkably  lengthened  and  the  leaf  attenuated  at  the  base  above 
the  vesicle  into  a  distinct  petiole.  The  M.  latifolia,  Bory,  is  intermediate  between  our

A  very  beautiful  and  rare  species  :  distinct  from  any  of  its  European  and  exotic  congeners  that  have  been 
described.     Mrs.  Sulivan's  specimens  are  much  finer  and  more  branched  than  those  from  Cape  Horn.

A  very  natural  little  group :  composed  of  a  few  species,  which  occupy  the  same  position  with  regard  to  the 
high-water  mark  in  the  Southern  Ocean,  that  Lichina  and  Catenella  do  in  the  Northern.  As  a  genus  it  differs  from 
Bostryckia,  Mont.,  only  in  the  more  simple  internal  structure  of  the  frond,  aud  broad,  apparently  septate,  tubes, 
surrounded  by  only  one  row  of  cells  occupying  the  centre  of  the  frond  :  in  habit  aud  other  respects  they  are  so 
closely  allied,  that  it  is  doubtful  whether  Stictosiphonia  should  not  rather  be  regarded  as  a  subgenus  of  Bostrychia. 
The  structure  of  the  frond  is  very  similar  to  that  of  Polysiphonia,  differing  chiefly  in  the  cellules  of  the  periphery 
being  very  short ;   whilst  those  constituting  the  axis  are  lengthened.

30.     IRID.EA,  Bory. 

1.  Irid^a  Radida,  Bory;  Fl.  Antarct.  Pt.  1.  p.  188. 

Hab.  Hermite  Island,  Cape  Horn ;  Falkland  Islands  and  Kerguelen's  Land,  very  abundant.  Cock- 
burn  Island ;  at  the  limits  of  southern  vegetation,  on  the  beach,  rare  and  bleached. 

So  abundant  are  the  Iridea  in  the  South  Polar  Oceau,  and  so  variable  in  their  form  and  texture,  that  we  can 
scarcely  hope  to  arrive  at  any  accurate  knowledge  of  the  species  until  they  shall  have  been  studied  in  a  living  state  ; 
and  then  it  is  not  improbable  that  the  genus  will  be  considerably  reduced ;  and  one  or  two  of  the  more  common 
species  be  found  to  assume  forms  as  dissimilar  as  those  of  our  Laurencia  pinnatifida. 

There  exist  in  the  Hookerian  Herbarium,  authentic  specimens  of  the  Fucus  bracteatus  of  Gmelin,  as  figured 
in  Turner's '  Historia,'  collected  both  at  the  Cape  of  Good  Hope  and  in  North  West  America,  by  Mr.  Menzies. 
These  are  (as  is  generally  the  case  with  the  specimens  of  the  larger  Fuci,  preserved  in  our  Herbaria)  smaller  and  of 
that  lanceolate  form  which  other  Iridea  present  in  a  young  state.  Then  texture  is  very  thick,  densely  cartila- 
ginous, opaque ;  and  covered  with  tubercles  which  fall  away,  leaving  a  cribriform  frond  both  when  immature  and 
older.  This  great  density  is  a  very  remarkable  character,-  and  observable  in  the  plant  here  referred  to  that  species, 
which,  when  full  grown,  becomes  broadly  ovate,  or  orbicular,  and  cordate  or  rounded,  or  narrowed  at  the  base  ; 
with  the  lamina  more  or  less  and  variously  divided,  sometimes  three  feet  broad,  or  upwards.  The  largest  speci- 
mens we  have  never  seen  attached,  though  they  are  abundant,  washed  up  on  the  beach,  and  probably  attain  then- 
great  size  on  the  outer  rocks. 

Since  the  publication  of  the  first  part  of  this  work,  we  have,  through  Dr.  Montagne's  kindness,  had  the  oppor- 
tunity of  inspecting  the  I.  laminarioides,  Bory,  of  Lord  Auckland's  Group  :  specimens  of  which  are  in  our  Herbarium 
from  the  same  island  ;  but  which  we  had  previously  regarded  as  a  more  debcate  state  of  /.  Radida.  Even  what  we 
consider  the  true  /.  Radida  of  Lord  Auckland's  Group  and  Kerguelen's  Land,  is  not  so  dense  in  the  frond  as  the 
specimens  of  the  Falkland  Islands  and  Cape  of  Good  Hope  are.  Both  this  and  the  following  species  have  the 
surface  frequently  covered  with  granules,  tubercles  or  pedicellate  pear-shaped  organs ;  or  in  the  young  state  with 
elongated  fleshy  bodies  similar  to  those  of  the  /.  stiriata,  Bory.  The  /.  stiriata,  according  to  the  descriptions,  may 
belong  to  a  state  of  this,  or  the  following,  or  many  other  forms  of  the  genus :  it  is,  however,  a  narrower,  smaller 
species,  with  a  much  more  dense  frond  than  even  /.  Radida.

Hab.  Hermite  Island,  Cape  Horn,  and  the  Falkland  Islands ;  both  varieties  very  abundant. 

This  species,  when  fresh,  well  deserves  the  brilliant  description  of  its  beautiful  tints,  given  by  M.  Bory 
on  the  authority  of  Admiral  D'Urville  and  M.  Gaudichaud.  It  is  one  of  the  most  common  Alga  of  the 
southern  extremity  of  America  and  the  Falklands.  In  its  younger  state,  the  fronds  are  obovate  or  spathulate,  like 
those  of  /.  laminarioides,  figured  by  Bory,  and  soon  expand  into  lamiuee,  variously  modified,  according  to  situa- 
tion and  exposure,  with  relation  to  the  force  of  the  sea,  the  nature  of  the  bottom,  the  currents,  depth,  and  protection 
afforded  by  other  Alga  ;  for  no  two  fronds  of  a  similar  shape  are  usually  to  be  found  within  a  few  yards.     Indeed,

I  question  whether  I.  micans  be  more  than  a  membranous  fonn  of  /.  Radula :  the  former  always  preferring  the 
quieter  harbours,  where  its  fronds  are  sometimes  as  thin  as  those  of  a  Deksseria,  quite  unfitted  to  withstand  the 
rough  seas  of  the  outer  coasts,  which  wash  the  almost  uninjured  fronds  of  the  /.  Radula  ashore  in  broad  sheets, 
as  large  and  as  red  as  an  ordinary  pocket-handkerchief. 

Though  sometimes  almost  equally  thin,  the  substance  of  the  /.  micam  is  never  so  membranous  as  that  of  a 
Deksseria.  The  colour,  though  not  so  bright  a  rose,  or  so  delicate  when  the  plant  is  dried,  is,  when  seen  in  the 
living  state,  much  more  varied  and  more  beautiful.  The  texture  is  such  that  the  slightest  motion  of  the  water 
causes  the  frond  to  undulate  throughout  from  the  base  upwards  without  falling  into  folds :  each  portion  of  the 
surface,  when  presented  at  a  certain  angle  to  the  eye,  reflecting  back  the  most  brilliant  metallic  tints  of  azure,  steel- 
blue,  pink,  and  purple.  A  more  beautiful  object  in  the  water  is  not  to  be  found  in  the  whole  order  of  Alqce  than 
this,  when  seen  from  a  boat  in  calm  weather  and  sunshine ;  though  it  is  seldom  that  such  opportunities  occur  in 
the  latitudes  it  inhabits.  I  have  not  been  able  to  detect  any  strise  on  the  surface  of  the  frond,  which  is  formed  of 
cells  so  densely  packed  that  they  coalesce  into  a  homogeneous  cartilaginous  tissue. 

We  have  no  hesitation  in  pronouncing  this  as  identical  specifically  with  the  I.  cordata  of  the  Banks  of  New- 
foundland and  the  Cape  of  Good  Hope ;  of  which  species  there  is  an  excellent  figure  in  the  '  Historia  Fucorum  ', 
coinciding  with  that  of  Bory  in  Duperrey's  Voyage.  The  descriptions,  both  of  Agardh  and  Turner,  particularly 
mention  the  iridescence  of  their  specimens.  The  only  differential  characters  noted  by  Bory,  who  justly  indicates 
the  close  affinity  of  /.  micans  with  /.  cordata,  are  the  slight  discrepancy  in  the  bluntness  of  the  apices  of  the 
fronds  and  depth  of  the  lobes  at  the  cordate  base.  We  are,  however,  well  assured  that  snch  characters  are  all  too 
slight;  for  we  could  not,  either  at  the  Cape  of  Good  Hope  or  the  Falkland  Islands,  distinguish  between  the  fonns  of 
this  Iridaa  with  a  cordate  and  those  with  a  cuneate  base  to  the  frond.  We  are,  however,  far  from  asserting  that 
there  may  not  be  from  the  two  last-named  localities  two  species  here  confounded  (one  of  which,  the  /.  micans  of 
Boiy,  is  the  same  with  the  F.  cordatus  of  Turner),  though  we  strongly  incline  to  the  opposite  opinion.

Certainly  distinct  from  P.  obtusa,  the  only  one  of  the  genus  hitherto  described  as  a  native  of  the  southern 
temperate  hemisphere,  but  perhaps  not  equally  so  from  P.  Brodiai.  Still  our  specimens  are  very  different  from  the 
ordinary  British  form  of  that  plant,  in  the  much  shorter  stipes,  and  larger  broader  frond,  which  is  much  less  lobed 
and  the  lobes  are  not  so  narrow  or  elongated,  or  separated  by  so  deep  a  sinus.

An  exceedingly  variable  plant  in  size  and  in  the  breadth  of  its  fronds,  simulating  in  the  high  southern  latitudes 
the  Chondnis  crispus,  as  far  as  locabty  and  abundance  are  concerned.  The  southern  species  representing  our  Cliondrus 
crispus  is  the  C.  tuberculatus  in  Lord  Auckland's  Group,  (where  the  Nothogenia  also  abounds,)  and  at  the  Cape  of

These  examples  so  entirely  accord  with  others  of  British  growth,  that  it  is  unnecessary  to  separate  them  spe- 
fically.  No  specimens  considered  by  any  systematic  botanist  to  belong  to  this  Gigartina  have  been  found  between 
the  latitudes  of  the  south  of  Europe  and  Kerguelen's  Land,  except  (according  to  Montagne)  at  Callao  :  yet  the 
genus,  under  one  or  other  of  its  Protean  aspects,  abounds  throughout  all  tropical  and  temperate  seas.

in  the  first  part  of  this  work,  I  have  had  the  advantage  of  re-studying  all  the  species  with  my  friend,  the  Rev.  Chnrchill 
Babington,  whose  profound  knowledge  of  the  forms  of  this  difficult  order,  and  acquaintance  with  the  most  recent 
writings  of  European  Lichenologists,  have  been  most  liberally  brought  to  bear  upon  this  part  of  the  '  Flora  Antarctica.'

Perhaps  the  handsomest  of  all  Lichens,  whether  we  regard  its  colour,  stature,  or  mode  of  growth,  and  yet  so 
variable  in  all  these  points,  that  the  extremes  are  scarcely  recognizable.  In  size  it  varies  from  a  few  lines  or  an 
inch,  with  capillary  stem  and  branches,  to  four  inches,  with  a  woody  stem  a  quarter  of  an  inch  in  diameter.  The 
colour  is  sometimes  wholly  (especially  in  var.  8)  black,  at  others  uniformly  yellow,  but  most  frequently  banded  with 
black,  especially  towards  the  apices  of  the  ramuli.  Old  specimens  turn  tawny  red,  as  do  all  when,  after  being 
dried,  they  are  soaked  in  warm  water.  The  apothecia  are  yellow,  grey  "or  deep  black.  The  surface  of  both  the 
stems  and  the  back  of  the  apothecia  is  more  or  less  tuberculated  or  pruinose,  smooth  or  much  wrinkled,  naked  or 
more  or  less  covered  with  longer  or  shorter  horizontal  terete  acuminated  ramuli.  The  apothecia  vary  exceedingly 
in  breadth,  from  two  or  three  lines  to  almost  half  an  inch ;  their  margins  are  smooth,  tuberculated  or  beset  with 
branching  ramuli ;  they  are  generally  terminal,  but  the  younger  appear  lateral  when  subtended  by  a  branch. 

It  is  in  the  Falkland  Islands  that  this  species  most  abounds,  covering  the  surface  of  the  Quartz  rocks  with  a 
miniature  forest,  seeking  the  most  exposed  situations,  and  there  attaining  its  greatest  size  and  beauty.  In  these 
Islands,  too,  all  the  five  varieties  I  have  enumerated  may  be  collected  within  a  few  feet  of  one  another,  and  so 
associated  as  to  leave  little  doubt  that  they  are  states  depending  on  age,  rather  than  marked  races.  The  var.  8. 
especially,  is  certainly  only  an  undeveloped  state,  which  does  not  bear  soredia  in  the  Antarctic  regions ;  or 
apothecia  either  in  Tasmania  or  in  the  Arctic  latitudes,  where  soredia  are  produced. 

The  structure  of  the  stem  of  this,  and  probably  of  some  other  Lichens,  presents  a  marked  analogy  with  that 
of  the  Laminarioid  Algse  described  at  p.  460,  The  central  thread  is  very  large,  composed  of  concentric  layers 
of  dense,  horny,  red  cellular  tissue,  gradually  passing  into  a  soft  white  pith,  enclosing  a  cavity.  Around  this 
horny  thread,  whose  edges  are  sharply  defined,  are  arranged  concentric  layers  of  a  spongy  cellular  substance,  which 
again  are  enclosed  in  a  cortical  layer,  as  dense  as  the  central,  and  to  which  the  yellow  and  black  hues  of  this 
Lichen  are  always  confined.  Thus,  proceeding  from  the  circumference,  there  is — 1st,  a  horny,  coloured,  cortical 
layer,  answering  to  what  is  called  the  cortical  layer  of  Lessonia,  and  to  which,  in  that  plant  also,  the  coloured 
chronmle  is  chiefly  confined ;  2nd,  the  layers  of  intermediate  lax  tissue,  successively  deposited,  though  much  more 
obscurely  so  than  iu  Lessonia ;  3rd,  the  central  thread  of  Usnea  which  is  a  stout  axis,  answering  to  the  elliptic  core 
of  Lessonia,  but  in  this  Lichen  becoming  so  lax  towards  the  centre  as  to  enclose  a  cavity  in  the  older  stems. 

We  have  never  observed  spores  in  any  specimens  of  this  Lichen,  from  whatever  place  collected,  though  we 
have  examined  very  many  apothecia  in  a  live  state,  as  well  as  after  being  dried,  both  young  and  old,  and  of  all 
colours,  both  black,  grey,  or  yellow.     Dr.  Montagne  (Voy.  au  Pole  Sud,  1.  c.)  has  been  similarly  unsuccessful. 


Falklands,  etc.]  FLORA  ANTARCTICA.  521 

The  range  of  this  Lichen  is  very  wide.  It  is  found  in  the  Arctic  regions  of  both  the  New  and  Old  World ;  on 
the  Andes  under  the  Equator,  at  an  elevation  of  11,000  feet ;  on  the  mountains  of  Tasmania  at  3,000  and  4,000  feet ; 
in  Chili,  the  Falkland  Islands,  Fuegia,  and  the  New  South  Shetlands.  Now  it  is  worthy  of  notice,  that  in  none  of 
the  Arctic,  the  equatorial,  or  south  temperate  latitudes,  does  this  plant  produce  apothecia  ;  and  that  in  the  Antarctic, 
where  alone  apothecia  have  hitherto  been  found,  these  are  always  barren.  Further  it  is  remarkable,  that  this 
Lichen  grows  only  where  no  other  Usiiea  is  found  in  fruit ;  and  is,  perhaps,  the  only  species  of  that  genus  which 
universally  inhabits  rocks ;  circumstances  which,  taken  together  with  its  increasing  in  luxuriance  with  the  exposure 
it  is  subjected  to,  suggests  the  possibility  of  its  being  a  state  of  some  other  species  of  this  highly  variable  and 
universally  diffused  genus,  and  that,  distinct  as  the  Antarctic  specimens  of  U.  melaxantha  appear,  they  may  owe  their 
characters  to  the  climate,  for  there  is  very  great  difficulty  in  defining  the  species  so  as  to  exclude  states  of  U.florida. 
Tn  South  Chili,  where  the  U.florida  commences  (proceeding  southwards),  we  have  specimens  of  U.  ceruchia, 
Mont.,  which  are,  perhaps,  states  of  U.  melaxantha.  Again,  in  Tasmania  I  am  unable  to  distinguish  some  specimens 
of  U.  barbata  and  U.florida  (?),  which  grow  on  the  trunks  of  dead  trees  in  the  higher  parts  of  the  island,  from  the 
U.  melaxantha  of  the  summit  of  Mount  Wellington  and  other  elevated  mountains.

So  closely  allied  to  the  U.  melaxantha,  that  I  advance  this  species  with  much  hesitation.  None  of  the 
Kerguelen's  Land  specimens  exactly  tally  with  any  of  its  congeners  from  other  Antarctic  localities,  but  approach  them 
very  nearly  indeed ;  so  much  so,  that  the  present  should  be  perhaps  regarded  as  a  permanent  variety  only.  If 
it  be  so,  it  is  singular  that  it  is  the  only  one  in  which  asei  have  hitherto  been  detected ;  these  are  abundant  in  all 
the  apothecia,  and  vary  much  in  size,  in  the  form  of  their  contained  spores,  and  in  the  arrangement  or  grouping 
of  these,  as  shown  in  the  accompanying  plate. 

This  is  by  far  the  most  handsome  vegetable  production  of  Kerguelen's  Land.

On  these  varieties,  or  rather  forms,  we  are  enabled  to  offer  the  following  observations : — 
The  var.  a.  is  exactly  the  English  R.  scopulorum,  and  the  only  one  which  produces  perfect  fruit  in  the  Falkland 
Islands.  Var.  /3.  is  found  in  New  Zealand,  and  in  fruit ;  also  abundantly  in  Brazil.  Var.  y.  and  f.  are  scarcely 
distinguishable  from  R.  fraxinea  of  Norfolk  :  small  specimens  exactly  resemble  R.  membrtmacea,  Laurer,  of  New 
Holland ;  it  is  a  very  common  form  in  the  Southern  Hemisphere.  Var.  S.  is  very  similar  to  the  Uraguay 
R.  prolifera,  of  Taylor.  Var.  e .  is  a  small  form  of  a  Chilian  variety.  The  var.  q.  inhabits  Chiloe,  and  approaches 
near  to  R.pollinaria. 


FalUanch,  etc.]  FLORA    ANTARCTICA.  523 

Dissimilar  though  the  states  of  this  plant  here  brought  together  are,  no  one  who  has  collected  them  together 
can  doubt  their  all  belonging  to  one  species,  which,  however,  seldom  fruits. 

M.  Fries  states  his  conviction  of  the  probability  that  all  the  European  Ramalinee  are  varieties  of  one  species, 
an  opinion  in  which  we  certainly  concur,  and  we  would  further  add  many  of  the  Exotic  (except  R.  inanis)  to  it. 
The  above  varieties  certainly  all  belong  to  one  species,  as  abundant  in  Cape  Horn  and  Fuegia  as  the  ordinary 
states  of  R.  scopulorum  are  in  Europe,  and,  however  unlike  some  of  these  forms  are  to  the  English  plant  of  that 
name,  the  one  called  a  here,  and  which  is  the  only  one  that  fruits,  is  in  no  way  to  be  distinguished  from  that  plant. 
Considering  how  plastic  the  Lichens  are  in  form  and  texture,  and  how  amenable  to  the  different  climatal  conditions,  it 
must  be  admitted  that  if  the  R.  scopulorum  of  England  were  to  inhabit  the  maritime  rocks  of  the  Falklands,  its  aspect 
would  be  changed ;  the  humidity  of  the  atmosphere  near  the  sea  of  these  islands,  being  much  greater  than  that  of 
similar  situations  in  our  own  country.  Again,  the  locality  inhabited  by  the  var.  a.,  namely,  rocks  at  a  considerable 
elevation  and  distance  from  the  ocean,  possesses  a  climate  more  assimilated  to  the  British  habitats  of  R.  scopulorum 
than  are  the  moist  rocks  at  a  lower  level,  and  hence  it  is  only  natural  to  suppose,  that  there  the  Falkland  Island 
form  would  assume  the  EngHsh.  Lastly,  the  universally  acknowledged  difficulty  of  defining  the  European  species, 
and  the  singular  abundance  of  forms  of  the  genus  exactly  similar  to  these  in  all  parts  of  the  world,  between 
Lat.  60°  N.  and  57°  S.,  together  with  the  fact  that  many  other  Lichens  are  equally  protean  and  widely  distributed, 
are  all  arguments  in  favour  of  the  Antarctic  species  having  a  common  origin  with  other  forms  of  the  genus 
inhabiting  the  Arctic,  Temperate,  and  Tropical  regions. 

The  genus  Ramalina,  in  the  Arctic  zone,  attains  the  parallel  of  69°,  on  the  shores  of  the  Polar  Sea  in  North 
America,  and  of  Lapland  in  Europe.

Hab.  Hermite  Island,  Cape  Horn;  amongst  moss  on  the  tops  of  mountains  only,  1,500-1,700  feet,

One  of  the  most  Arctic  of  plants,  having  been  collected  on  Ross  Islet,  the  northernmost  known  land  in 
Em-ope  (81°  N.),  and  in  Melville  Island  (76°),  on  the  limits  of  Arctic  American  vegetation.  It  inhabits  the  level 
of  the  ocean  only  within  the  Arctic  circle,  or  in  the  extremely  cold  plains  of  Central  Russia  (as  Moscow,  55° N.) 
Dahuria  in  Asia,  50°  N.,  and  in  North  America  (as  Labrador,  55°  N.) ;  thence,  in  progressing  south,  it  asceuds  ; 
attaining  the  tops  of  our  Scotch  Alps,  4,000  feet  (56°  N.),  about  10,000  feet  on  the  Swiss  Alps  (46°  N.),  9,000 
feet  on  the  top  of  the  Pyrenees,  and  4,000  feet  on  the  mountains  of  North  Carolina  and  Virginia  (in  36°  N.). 
The  last  locality  is  the  lowest  latitude  it  attains  in  the  Northern  Hemisphere ;  in  the  Southern  it  re-appears  only 
on  the  extreme  point  of  America,  and  there  is  confined  to  the  pinnacles  of  the  very  highest  mountains.  There  is 
perhaps  no  vegetable  common  to  both  hemispheres  more  typical  of  extreme  cold  than  this  Lichen,  which  is  further 
interesting  from  being  the  reputed  cure  for  consumption,  and  the  only  plant  of  that  order  extensively  used  in  medicine.

This,  again,  is  an'instance  of  the  re-appearance  of  a  Northern  and  Arctic  Lichen  in  the  Southern  Hemisphere 
only  under  Antarctic  skies.  The  C.  glauca  finds  its  principal  parallel  in  Scotland,  central  and  northern  Europe,  and 
sub-arctic  America,  wandering  as  far  south  as  the  Swiss  Alps  and  mountains  of  the  Canary  Islands.  It  is  not 
nearly  so  Arctic  as  the  O.  Idandica,  not  being  found  in  Spitsbergen  or  Melville  Island,  or,  according  to  Richardson 
anywhere  to  the  northward  of  54°  in  Arctic  America.     Wahlenberg  states  it  to  be  rare  in  Lapland.

The  most  magnificent  of  Lichens,  whether  we  regard  the  size  of  the  thallus,  which  often  is  a  foot  and  upwards 
across,  the  general  aspect,  or  the  size  and  beautiful  colour  of  the  frond  and  copious  apothecia.  Its  European  range 
is  very  northern,  being  confined  to  Scandinavia,  reaching  Lapland  but  not  the  islands  beyond,  nor  inhabiting 
any  countries  south  of  the  Baltic.  In  North  America  it  ranges  over  the  wooded  regions  and  barren  lands, 
54°-69°,  and  to  the  west  of  the  Rocky  Mountains  descends  to  Eort  Vancouver,  in  Lat.  46°  N.

Very  abundant  in  Tasmania  and  New  Zealand,  also  found  iu  Lord  Auckland's  group  and  Campbell's  Island. 
In  Europe,  it  ranges  from  Switzerland  to  Sweden  and  Norway  ;  in  America,  from  Mexico  to  Sitka,  but  does  not 
proceed  so  far  north  on  the  east  of  the  Rocky  Mountains ;  it  also  inhabits  the  West  Indies,  Colombia,  the  Cape  of 
Good  Hope,  and  other  warm  climates.  Altogether  it  is  a  plant  which  does  not  shim  the  cold  so  markedly  as  do 
either  of  the  following  species,  for  it  (the  var.  scutata)  is  also  found  as  far  as  the  northern  limits  of  the  forest 
regions  of  Arctic  America.

In  the  Southern  Hemisphere  the  P.  canina  has  been  found  in  Juan  Fernandez  only.  Its  range  in  the  Northern 
is  very  wide,  commencing  in  Mexico  it  is  dispersed  as  far  north  as  Canada  on  the  east  coast,  and  Sitka  on  the 
west.  In  Europe  it  is  frequent  from  the  Alps  to  Lajjland,  but  does  not  inhabit  the  Arctic  Island  of  Spitzbergen  in 
Europe,  or  the  shores  of  the  Polar  Sea  and  Islands  beyond  in  America,  where  the  P.  aptltosa  abounds,  a  species 
not  hitherto  found  in  the  Antarctic  regions.     The  Falkland  Island  specimens  are  in  a  very  imperfect  state.

The  specimens  are  in  a  very  unsatisfactory  state,  being  stunted  and  barren.  They,  however,  closely 
resemble  dwarf  Scotch  and  Arctic  individuals  of  the  plant  in  question,  differing  chiefly  in  the  smoother  thallus 
and  occasional  buds.  The  range  of  the  species  is  not  wide  :  Lapland  and  Switzerland  are  its  Northern  and 
Southern  European  limits.  In  North  America  it  inhabits  the  United  States,  Canada,  and  the  Columbia  river. 
Kerguelen's  Land  is  the  only  recorded  habitat  in  the  Southern  Hemisphere.

This,  again,  has  not  been  observed  elsewhere  in  the  Southern  Hemisphere.  In  the  Northern  it  is  confined  to 
the  temperate  latitudes,  both  of  Europe  and  North  America,  ranging  in  the  latter  from  the  middle  United  States 
to  Canada,  and  in  Europe  from  Lapland  to  Switzerland  and  the  Pyrenees,  where  it  is  the  only  species  of  the  genus 
inhabiting  the  top  of  the  Pic  du  Midi  (9,000  feet).

group,  Great  Britain  and  Ireland,  attaining  its  northern  limit  at  Inverary  in  Scotland  (Lat.  56°  N.),  which  singularly 
coincides  with  the  latitude  of  the  most  southern  habitat,  namely,  Cape  Horn.  The  xax.  gilva  is  certainly  only  a 
variety,  without  the  pulverulent  lines  on  the  upper  surface.  The  rimae  are  sometimes  white  in  this  species,  when 
it  becomes  exceedingly  difficult  to  distinguish  it  from  some  of  its  congeners.

Fuegian  forest,  rendering  it  a  very  conspicuous  plant.  It  is  also  found  in  Chiloe  and  Juan  Fernandez,  and 
in  the  Old  World  it  inhabits  New  Zealand.  Though  an  ally  of  S.  aurata,  it  is  perfectly  distinct  from  that 
plant,  especially  in  the  granular  and  not  powdery  margins  of  the  thallus,  also  in  size  and  general  features.  It  is 
certainly  as  well  marked  as  any  species  of  Lichen  confined  to  the  southern  latitudes.

This  species  was  not  seen  at  Cape  Horn  or  the  Falkland  Islands :  but  we  have  specimens  from  Chiloe  and 
Juan  Fernandez.  It  is  singular  that  a  Lichen,  which  abounds  in  Lord  Auckland's  group  and  Campbell's  Island, 
should  not  be  also  found  at  Cape  Horn;  and  that  the  S.  endochrysa  of  Cape  Horn  is  found  in  New  Zealand, 
but  does  not  spread  so  far  south  as  Lord  Auckland's  group.  The  much  greater  cold  of  Fuegia  might  be  prejudicial 
to  the  S.  orygmaa,  but  there  is  no  apparent  reason  for  S.  oidoclirym  being  foreign  to  Lord  Auckland's  group.  I 
suspect  that  the  Acharian  plant  from  Staten  Land,  referred  to  as  S.  orygmaa,  is  the  S.endocltrym,  Del;  and  that  the 
specimens  were  received  from  Menzies. 

There  are  very  remarkable  differences  between  the  Lichens  of  those  two  divisions  of  Antarctic  botany  which 
are  here  adopted  :  the  most  salient  features  of  which  consist  in  the  presence  or  abundance  of  the  following 
Lichens  in  only  one  of  the  divisions.

This  remarkable  predominance  of  certain  very  widely  distributed  forms  in  the  southern  extremity  of  the 
Western  Hemisphere,  and  the  absence  of  the  same  in  similar  positions  in  the  Eastern,  admit  of  no  explanation, 
beyond  what  climate  will  afford.

Of  this  we  possess  an  authentically  named  specimen,  gathered  and  labelled  by  Menzies  himself :  in  it  the 
cyphelke  are  pale  yellow  ;  as  Montague  describes  those  of  his  S.  hirsuta.  M. Delise  does  not  seem  to  have  understood 
the  species,  and  describes  apparently  a  very  different  plant  under  this  name.  It  is  closely  allied  to  the  S.  comet  ia 
of  Peru,  in  which  the  apothecia  are  fringed  with  much  longer  hairs,  and  also  to  the  S.  Humboldtii,  Hook.,  another 
Peruvian  plant  with  fringed  apothecia ;  but  both  of  these  have  white  cyphellae. 

Sticta  obwluta  is  also  a  native  of  South  Chili  and  Juan  Fernandez.

A  New  Zealand  and  Tasmanian  species,  agreeing  remarkably  well  with  the  figure  and  description  of  Delise, 
except  in  the  under  surface  being  more  pale  than  is  described  by  that  author.  It  differs  from  S.faveolata,  Debse, 
in  the  much  longer  and  narrower  lobes  and  paler  under  surface,  and  in  the  absence  of  the  granulations  on  the 
upper.  The  apothecia  are  all  marginal  when  young,  deeply  concave,  the  older  in  these  specimens  convex,  with 
a  very  narrow  margin  :  this  convexity  is  not  a  character  to  which  too  much  importance  should  be  attached,  because 
the  apothecia  of  many  allied  species  vary  extremely  on  the  same  specimen,  from  concave  to  convex ;  and  these 
differences  do  not  in  such  species  depend  on  age. 

This  is  the  S.  Richardi  of  the  first  part  of  this  work,  but  not  of  Montagne,  the  true  S.  Richardi  having  much 
broader  lobes  to  the  thallus,  more  or  less  rough  or  even  scrobiculate  on  the  upper  surface,  and  almost  wholly- 
smooth  on  the  under.  It  is  very  nearly  allied  to  the  true  S.  carpoloma,  but  differs  in  the  white  cyphelhs,  and 
like  many  others  of  the  faveolate  group  it  is  possibly  only  a  variety  of  S.  damacornis. 

We  have  specimens  from  the  Chonos  Archipelago,  from  Chiloe  and  the  Island  of  Huaffa  (on  the  coast  of  South 
Chili),  agreeing  entirely  with  one  another  in  the  (when  dry)  pale  yellow-brown  shining  colour  of  the  upper  surface. 
The  New  Zealand  and  Lord  Auckland's  Island  examples  are  rather  paler  :  in  all,  the  under  surface  of  the  lobes  is 
naked  and  tawny  yellow  towards  the  apex.

Hab.  Strait  of  Magalhaens ;  Hombron. 

We  have  thought  it  possible  that  what  we  have  called  S.  Billardieri,  Del.,  may  be  the  S.faveolata  of  Montagne 
(in  Voy.  au  Pole  Sud);  especially  as  that  author  makes  no  mention  of  the  granular  Hues  on  the  upper  surface  so 
expressly  alluded  to  by  Delise  (under  S.  carpoloma);  and  also  from  this  S.faveolata  of  Montagne  being  found  by 
the  officers  of  the  French  South  Polar  Expedition,  both  in  the  Strait  of  Magalhaens  and  Lord  Auckland's  group. 
In  the  absence,  however,  of  authentic  specimens,  and  of  any  explanatory  note  by  Montagne  (whose  specimens  were 
very  insufficient)  on  the  species  he  calls  S.faveolata,  we  are  obliged  to  abide  by  the  published  figures  of  Delise. 

The  lacunose  fronded  Sticta  with  white  soridia,  forrn  a  most  natural  group  of  species,  so  inextricably  con- 
founded by  nature,  if  they  be  really  and  truly  species  at  all,  that  we  have  failed  in  discovering  limits  to  the 
variations  of  any  of  them.  Even  the  colour  of  the  cyphella?  is  very  unsatisfactory,  there  being,  between  the  snow- 
white  of  the  S.  Billardieri  and  dirty  yellow  of  some  others,  all  intermediate  tints ;  and  in  the  same  species,  almost 
on  the  same  specimen,  of  Tasmanian  examples  of  S.faveolata  (?),  it  is  impossible  to  say  whether  the  cyphellse  are 
dirty  white  or  pale  yellow  ;  whilst  other  specimens,  in  all  respects  similar,  have  their  colour  well  pronounced.

The  specimens  examined,  when  preparing  the  short  notice  of  the  Antarctic  Lichens  for  the  London  Journal  of 
Botany,  were  very  imperfect ;  and  their  under-surface  exhibiting  no  cyphellae,  we  referred  them  to  the  S.  scrobiculata, 
which  they  considerably  resemble,  especially  in  colour,  and  in  their  fetid  scent  when  moistened.  Other  specimens 
showed  white  cyphellae  in  abundance,  and  allied  the  plant  so  closely  to  the  European  S.  limbata,  that  we  can  detect 
no  marked  difference  between  them,  beyond  what  is  afforded  by  the  colour  of  the  powdery  granulations  on  the 
surface. 

Delise's  description  of  S.  Thouarsii  leaves  no  doubt  in  our  mind  of  this  being  his  plant.  The  apothecia  are 
unknown.     Fuegian  specimens  are  of  a  paler  colour  than  the  Falkland  Island  ones.

We  have  added  a  figure  of  this  much-disputed  species,  concerning  which  we  have  fallen  into  an  error  in  the 
previous  part  of  this  work,  having  regarded  it  as  synonymous  with  the  S.  glabra  of  Lord  Auckland's  group  and 
Tasmania  (probably  the  S.  Delisea  Fee,),  and  which  differs  from  the  S.  Freycinet'd  principally  in  the  very  shallow, 
not  deeply  cupped  apothecia. 

Fueria  and  the  Island  of  Juan  Fernandez  are  the  only  localities  in  which  we  know  this  species  to  occur.

Our  specimens,  which  are  small  and  barren,  differ  in  colour  and  in  the  less  decidedly  marked  costae,  from 
those  of  New  Zealand ;  the  lobes  also  are  occasionally  furnished  with  an  isidiophorous  border.  The  thallus  is 
about  au  iuch  and  a  half  high,  the  upper  surface  of  a  dirty  greenish-brown,  the  under  pale  yellow-brown  and 
uniformly  covered  with  a  short  tomentum,  into  which  the  concolorous  and  rather  large  cyphellee  are  sunk.  They

affords  another  remarkable  instance  of  this  anomalous  distribution.  Except,  perhaps,  the  Cenmnyce  rangiferina, 
it  is  the  very  commonest  of  all  Lichens  in  the  subalpine  districts  of  Britain  and  Central  Europe,  in  the  Alpine

regions  of  Southern  Europe  ascending  to  the  summit  of  the  Pyrenees,  and  to  the  level  of  perpetual  snow  on 
the  Alps.  Again,  in  the  Arctic  zone  it  is  found  carpeting  the  otherwise  naked  steppes  of  Asia  and  the  barren 
lands  of  America,  thence  reaching  the  ultima  thide  of  vegetable  life  in  Melville  Island  and  Ross  Islet.  To  the 
south  of  its  principal  parallel  it  inhabits  the  Canary  Islands,  and  a  variety  is  seen  on  the  Andes  of  Mexico  and 
Colombia.  Still  further  south  it  is  replaced  in  all  longitudes  by  the  following  species,  being  itself  unknown 
in  the  Southern  Hemisphere  except  at  Cape  Horn  and  Kerguelen's  Land,  where  it  re-appears  in  abundance.  To 
reconcile  this  singular  fact  with  the  views  of  those  who  suppose  it  to  have  migrated  into  Kerguelen's  Land,  it  is 
almost  necessary  to  consider  the  S.  ramulosum,  wliich  inhabits  Lord  Auckland's  group,  Campbell's  Island,  Tasmania, 
and  the  northern  parts  of  Fuegia,  as  a  southern  variety  of  S.  corallinum,  which  has,  in  Kerguelen's  Land  and  Cape 
Horn,  reverted  to  the  northern  form.

Hab.  Strait  of  Magalhaens,  Capt.  King.     Chonos  Archipelago,  C.  Darwin,  Esq. 

This  widely  distributed  species  replaces  in  the  Southern  Hemisphere,  to  a  considerable  degree,  the  S.paschale 
and  coral! iiium  of  the  Northern,  but  not  fully ;  for  it  only  enters  what  we  have  elsewhere  denned  to  be  the  Antarctic 
zone  of  vegetation,  not  reaching  the  Falkland  Islands,  the  southern  parts  of  the  Fuegian  Islands  or  Kerguelen's 
Land.  In  the  Old  World  it  first  appears  in  Bourbon,  thence  ranging  from  the  Philippines,  through  Java,  Australia, 
the  South  Sea  Islands,  Tasmania  and  New  Zealand,  to  Lord  Auckland's  group  and  Campbell's  Island,  abounding 
iu  rocky  and  damp  places,  also  on  the  trunks  of  large  trees.  In  the  New  World  it  commences  in  the  West  Indian 
Islands,  whence  Swartz  originally  procured  it,  and  ruus  through  every  parallel  of  latitude  to  the  Strait  of  Magalhaens. 

As  a  species  S.  ramulosum  appears,  at  first  sight,  abundantly  distinct  from  8.  corallinum,  nor  does  it  display  a 
tendency  to  assume  any  northern  form  of  the  genus  in  the  Strait  of  Magalhaens.  In  Tasmania,  again,  where  it 
ascends  the  mountains  and  becomes  dwarfish,  its  lateral  ramuli  are  still  slender  and  fibrous,  typical  of  the 
species.  On  the  other  hand,  some  of  the  tropical  specimens,  especially  those  from  the  Equatorial  Andes  (where 
both  species  occur),  appear  intermediate  between  S.  ramulosum  and  corallinum ;  insomuch  that  it  becomes  a  matter 
of  opinion  alone,  whether  the  S.  ramulosum-  should  be  considered  a  southern  state  of  S.  corallinum,  owing  its  greater 
development  to  the  more  uniform  temperature  and  humidity  of  the  localities  it  affects  in  the  Southern  Hemisphere ; 
or  whether  these  are  two  species,  one  originating  in  the  Southern  Hemisphere,  and  one  in  the  Northern,  meeting 
under  the  Line,  and  there  varying  into  the  similitude  of  one  another.

530  FLORA    ANTARCTICA.  Fuegia,  the 

A  conrmon  Antarctic  American  plant,  rarer  in  Tasmania,  and  replaced  in  Lord  Auckland's  group  by  S.  tenerum. 
Its  range  is  very  wide  in  both  hemispheres,  from  within  the  Arctic  circle  of  the  New  and  Old  Worlds,  attaining 
Walden  Island  north  of  Spitzbergeu,  within  9°  of  the  North  Pole,  stretching  south,  throughout  Europe,  to  the 
Asturias,  Switzerland,  and  Madeira,  and  in  America  to  Newfoundland.

Hab.  Hermite  Island,  Cape  Horn ;  most  abundant  on  the  hills.    Clionos  Archipelago,  C.  Darwin,  Esq. 

In  the  former  part  of  this  work  we  have  pointed  out  the  characters  which  distinguish  this  species  from  the 
S.  coralloides.  It  is  much  more  frequent  in  Tasmania  and  New  Zealand  than  in  South  America,  in  the  latter 
country  having  been  only  found  at  Cape  Horn,  Euegia,  Chiloe,  and  the  Chonos  Archipelago. 

I  know  of  no  Lichen  which  exhibits  so  well  the  successive  development  of  "laminae  proligerae"  in  the  same 
apothecium.  A  vertical  section  of  the  youngest  fruit  shows  two  strata,  parallel  to,  or  rather  concentric  with,  one 
another.  Of  these,  the  upper  is  fully  ripe  long  before  the  bursting  of  the  apothecium.  It  consists  of  innumerable 
filiform  asci,  containing  from  eight  to  thirty  and  more  sporules.  The  sporules  are  vertically  arranged  and  so  densely 
packed  that  each  ascus  resembles  a  moniliform  filament :  the  lower  are  smaller,  the  upper  gradually  larger;  none 
however,  attain  then  full  size  till  after  the  absorption  or  disappearance  of  the  walls  of  the  ascus  ;  when  they 
escape  as  spherical  bodies,  surrounded  by  a  narrow  transparent  margin. 

The  thallus  of  this  genus  consists  of  a  firm  crustaceous  transparent  cortex,  whose  inner  edge  is  sharply  defined, 
enclosing  a  mass  of  longitudinally  arranged,  matted,  curved,  dry  filaments.  These  filaments  are  cylindrical,  terete, 
sparingly  supplied  with  very  short  ramuli,  and  truncate  or  obtuse  at  either  extremity :  they  entirely  surround  the 
nucleus  of  the  very  immature  apothecium.

laminae  prbligerse ;  9,  asci  and  spores ;  10,  young  (or  possibly  abortive)  asci ;  11,  mature  ascus ;  12,  spores ;

These  specimens  are  identical  with  the  English  plant  so  called.  It  is  also  an  Auckland  Island  species,  and  is 
found  in  various  countries,  both  within  and  without  the  tropics,  as  far  north  as  the  barren  lands  bordering  the 
Polar  Sea  in  Arctic  America.  In  Europe,  Wahlenberg  remarks,  that  it  does  not  occur  in  any  part  of  Scandinavia. 
In  the  Southern  Hemisphere  it  grows  on  the  South  American  Andes  and  in  Van  Diemen's  Land.

With  figures  of  the  natural  size,  drawn  and  engraved  from  specimens  chiefly  in  the  collection  of  Hugh  Cuming,  Esq.,F.L.S.,  &c, 

By  G.  B.  SOWERBY,  F.L.S. 

The  '  Conchologia  Iconica,'  of  which  forty  Numbers  containing  three  hundred  and  twenty  quarto  plates  are 
now  published,  was  commenced  in  January  1843,  with  the  view  of  presenting  a  faithful  and  characteristic  illustration 
of  every  living  species  and  remarkable  variety  of  Shell,  collected  up  to  the  time  of  publication ;  and  the  liberal  reception 
it  has  met  with  not  only  throughout  England  and  the  Continent,  including  the  cities  of  Paris,  Brussels,  Vienna,  Bremen, 
Turin,  Berne,  Berlin,  Copenhagen,  Stockholm,  Moscow,  and  St.  Petersburgh,  but  in  the  United  States,  Chili,  Mauritius, 
and  British  India,  has  enabled  the  author  to  avail  himself  of  every  improvement  which  typography  and  the  arts  employed 
for  illustration  are  now  capable  of. 

The  magnificent  collection  of  Hugh  Cuming,  Esq.,  of  surpassing  novelty  and  beauty,  is  most  zealously  devoted  to  the 
undertaking,  and  the  valuable  information  respecting  localities,  and  circumstances  of  habitation  with  which  the  possessor, 
from  his  enterprizing  personal  experience,  is  so  richly  stored,  is  generously  contributed  to  the  advancement  of  the  work. 

The  author  has  besides  to  return  his  sincere  thanks  to  many  local  and  far-distant  correspondents  for  their  kind 
co-operation  by  the  loan  of  specimens,  including  H.M.  The  King  of  Denmark,  the  Marquis  of  Northampton,  J.  E.  Gray, 
Esq.,  of  the  British  Museum,  Miss  Saul,  Miss  Steere,  Wm.  Metcalfe,  Esq.,  J.  S.  Gaskoin,  Esq.,  William  Walton,  Esq., 
Sylvanus  Hanley,  Esq.,  and  the  Rev.  F.  J.  Stainforth  of  London ;  Thomas  Norris,  Esq.,  of  Preston  ;  J.  Dennison,  Esq.,  of 
Liverpool;  Thomas  Lombe  Taylor,  Esq.,  of  Starston;  Dr.  Knapp  of  Edinburgh;  H.  H.  White,  Esq.,  of  Clapham;  John 
Adamson,  Esq.,  of  Newcastle ;  E.  G.  L.  Gruner,  Esq.,  of  Bremen,  Dr.  Menke  of  Pyrmont,  and  M.  Delessert,  M.  Deshayes, 
and  M.  Alcide  D'Orbigny,  of  Paris. 

The  chief  merit  of  the  '  Conchologia  Iconica  '  consists  in  having  all  the  species  illustrated  of  the  natural  size, 
excepting  those  which  on  account  of  their  minuteness  require  magnifying,  and  great  attention  is  given  to  avoid  any 
exaggeration  in  the  colouring. 

The  arduous  researches  of  Mr.  Cuming,  both  in  the  eastern  and  western  hemispheres,  have  supplied  his  collection 
with  such  an  extensive  and  interesting  number  of  undescribed  species  of  Shells,  that  a  very  large  proportion  of  those 
hitherto  figured  are  entirely  new  to  science.

THEIR   BOTANICAL   CHARACTERS,    HABITS    OF   GROWTH,   MICROSCOPIC 

STRUCTURE,  NUTRITIOUS  PROPERTIES,  AND  MODE  OF

BY  DAVID  BADHAM,  M.D. 


In  treating  of  the  eatable  kinds  of  Mushroom,  the  author  desires  to  secure 
for  an  undeservedly  neglected  subject,  the  curiosity  and  interest  of  those 
who,  having  an  inclination  for  the  study  of  Natural  History,  have  not  yet 
determined  on  what  particular  province  to  devote  their  powers  of  observa- 
tion and  experiment.  For  the  sake  of  such  readers,  the  outlines  of  Myco- 
logy will  precede  the  description  of  the  "  Esculent  Mushrooms "  of  England. 

It  is  for  this  latter  portion  of  the  volume,  however,  that  the  Author 
anticipates  the  greater  number  of  readers,  inasmuch  as  he  will  treat  of  a 
most  excellent  article  of  food,  the  chief  varieties  of  which  have,  through 
prejudice,  and  the  want  of  fixed  discriminating  signs,  been  hitherto  suffered 
to  perish  unused ;  but  which,  a  Little  easily  acquired  information,  may  at 
once  render  a  wholesome,  costless,  and  palatable  species  of  nourishment. 

It  is  not  to  be  wondered  at  that  the  descriptions  of  the  Esculent  Funguses 
of  the  continent,  which  may  be  found  here  and  there  in  scientific  and  ex- 
pensive works,  have  never  yet  enabled  us  to  turn  to  account  the  treasures  of 
our  own  forests  and  meadows.  Such  a  purpose  can  only  be  answered  by  the 
substitution  of  popular  for  technical  terms,  and  by  an  exact  delineation  of  the 
various  esculent  kinds,  occasionally  contrasted  with  those  noxious  specimens 
which  they  most  closely  resemble.  Accordingly,  the  descriptions  in  the 
present  work,  are  written  in  the  plainest  possible  manner,  and  the  plates 
are  finished  with  such  accuracy,  that  no  perplexity  or  misgivings  as  to  the 
nature  of  any  Fungus  will  remain  on  the  minds  of  those  who  study  them 
accurately. 

A  chapter  is  added  on  the  nutritious  properties  of  the  various  kinds, 
and  one  also  on  the  best  modes  of  cooking  and  preserving  them.

ELEMENTS  OF  CONCHOLOGY, 

BEING 

A  SYSTEMATIC   CLASSIFICATION  OP  ALL  THE  SPECIES  OP  RECENT   SHELLS   KNOWN 

UP  TO  THE  TIME  OF  PUBLICATION,  WITH  DESCRIPTIONS  OF  THEIR 

FORMATION,  GROWTH,  DEPOSITION  OF  COLOURS, 

AND  A  POPULAR  ACCOUNT  OP 

THE  ORGANIC  STRUCTURE,  HABITS,  AND  CALCIFYING  FUNCTIONS  OF  THEIR 
ANIMAL    INHABITANTS. 

By  LOVELL  REEVE,  A.L.S.,  Etc., 

Author  of  the  'Conchologia  Systematica',  *  Conchologia  Iconica',  &c. 

***  To  be  completed  in  twelve  Monthly  Parts,  illustrated  with  forty-eight  Plates  of  Shells, 
of  the  natural  size,  and  twelve  Plates  of  Shells,  of  the  same  dimensions,  with  the  Animal  crawling 
from  each  as  it  appears  in  a  living  state. 

The  object  of  the  present  work  is  to  furnish  the  '  Collector  of  Shells  '  with 
a  methodical  arrangement  and  enumeration  of  species,  illustrated  by  a  shell- 
figure  of  every  genus,  and  several  figures  of  shells  with  the  animal  as  it  appears 
in  a  living  state,  accompanied  by  a  popular  summary  of  those  grand  truths  in 
the  physiological  history  of  the  Mollusca,  which  have  been  elicited  from 
the  investigations  of  recent  travellers ;  to  demonstrate  the  habits  and  organic 
peculiarities  of  this  mystic  tribe  of  animals  by  a  careful  system  of  generali- 
zation ;  and  to  lead  him  to  meditate,  whilst  pondering  over  the  treasures  of 
his  cabinet,  upon  the  nature  and  zoological  affinity  of  those  imperishable 
records  of  existence  he  so  delights  to  contemplate. 

It  is  not  the  author's  intention  to  treat  of  the  anatomy  of  the  Mollusca  in 
detail,  because  he  cannot  boast  of  sufficient  practical  acquaintance  with  the 
dissecting-knife  to  enable  him  to  undertake  it  with  satisfaction ;  for  that  de- 
partment of  their  natural  history  he  must  refer  the  student  to  the  writings  of 
those  authors  whose  professional  skill  and  education  have  better  fitted  them 
for  the  task.  It  is  intended  to  treat  of  the  external  form,  and  of  the  more 
prominent  features  of  organization ;  and  especially  such  as  tend  to  elucidate 
peculiarities  of  habit  or  the  characters  selected  for  their  generic  arrangement. 

For  drawings  of  the  living  mollusks  the  author  will  have  recourse  to  those 
invaluable  records  of  zoological  discovery  executed  under  the  auspices  of  the 
French-  Government,  which,  on  account  of  their  enormous  cost,  are  as  sealed 
books  to  the  naturalists  of  this  country ;  •  and  he  will  be  mainly  indebted  for 
information  on  their  habits  and  circumstances  of  existence  to  the  enter- 
prising exertions  of  Hugh  Cuming,  Esq.,  whose  free  manner  of  communi- 
cating the  different  incidents  which  arrested  his  attention  during  fourteen 
years  of  indefatigable  research,   cannot  be  spoken   of  in  too  high  terms. 

The  Elements. of  Conchology  are  addressed  exclusively  to  the  '  Collector 
of  Shells';  and  the  author  desires  the  work  to  be  simply  recorded  as  an 
effort  to  induce  a  more  legitimate  tone  of  enquiry  amongst  amateur  concho- 
logists,  into  the  nature  and  origin  of  those  beautiful  objects  which  afford 
them  so  much  intellectual  recreation  and  amusement.
