  one 
  species 
  of 
  Carex 
  are 
  enumerated 
  from 
  this 
  part 
  of 
  South 
  

   America, 
  of 
  which 
  thirty 
  are 
  endemic 
  and 
  fifteen 
  only 
  known 
  

   from 
  tropical 
  South 
  America 
  besides 
  ; 
  four 
  varieties 
  are, 
  more- 
  

   over, 
  not 
  known 
  from 
  elsewhere, 
  while 
  the 
  typical 
  forms 
  occur 
  

   in 
  the 
  northern 
  hemisphere; 
  — 
  G. 
  vulgaris 
  Fr. 
  is 
  the 
  only 
  

   cosmopolitan 
  species 
  among 
  them. 
  The 
  systematic 
  arrange- 
  

   ment 
  of 
  these 
  species 
  is 
  very 
  interesting, 
  and 
  three 
  sub- 
  

   genera 
  are 
  adopted 
  : 
  Vignea, 
  Vigneastra 
  and 
  Eucarex. 
  These 
  

   are 
  again 
  divided 
  into 
  twenty 
  sections, 
  mostly 
  those 
  of 
  Drejer, 
  

   Fries 
  and 
  Tuckermann, 
  while 
  the 
  subsections 
  are 
  arranged 
  in 
  

   accordance 
  with 
  the 
  number 
  and 
  position 
  of 
  the 
  spikes: 
  mono- 
  

   stachyous, 
  homostachyous 
  and 
  heterostachyous, 
  of 
  which 
  the 
  first 
  

   one 
  is 
  generally 
  supposed 
  to 
  represent 
  the 
  oldest 
  type. 
  

  

  The 
  species 
  are 
  very 
  carefully 
  described 
  in 
  Latin, 
  and 
  a 
  num- 
  

   ber 
  of 
  varieties 
  are 
  included. 
  Synonyms 
  are 
  also 
  given 
  in 
  con- 
  

   nection 
  with 
  reference 
  to 
  literature, 
  besides 
  the 
  habitat 
  and 
  geo- 
  

   graphical 
  distribution. 
  The 
  author 
  has 
  beyond 
  doubt 
  been 
  very 
  

   successful 
  in 
  his 
  attempt 
  to 
  classify 
  this 
  difficult 
  genus 
  in 
  natural 
  

   sections, 
  similar 
  to 
  those 
  suggested 
  by 
  Drejer 
  as 
  far 
  as 
  concerns 
  

   the 
  morphological 
  characters, 
  and 
  the 
  paper 
  constitutes, 
  there- 
  

   fore, 
  an 
  important 
  basis 
  for 
  future 
  research. 
  However 
  the 
  mor- 
  

   phological 
  characters, 
  striking 
  as 
  they 
  may 
  appear, 
  are 
  often 
  

   very 
  deceiving. 
  We 
  wish 
  that 
  the 
  author 
  had, 
  at 
  least 
  to 
  some 
  

   extent, 
  compared 
  his 
  morphological 
  classification 
  with 
  such 
  

   anatomical 
  studies 
  in 
  Carex, 
  of 
  which 
  the 
  literature 
  possesses 
  

   such 
  interesting 
  and 
  important 
  contributions 
  as 
  those 
  of 
  Lemcke, 
  

   Mazel 
  and 
  others. 
  The 
  external 
  structure 
  of 
  utriculus, 
  for 
  

   instance, 
  is 
  often 
  very 
  uniform 
  in 
  many 
  species, 
  hence 
  these 
  are 
  

   classified 
  in 
  one 
  section, 
  yet 
  an 
  anatomical 
  study 
  of 
  this 
  little 
  

   organ 
  reveals 
  a 
  number 
  of 
  striking 
  divergences, 
  which 
  may 
  prove 
  

   useful 
  not 
  only 
  in 
  classifying 
  the 
  species 
  among 
  themselves, 
  but 
  

   also 
  in 
  establishing 
  natural 
  sections.

  A 
  complete 
  catalogue 
  of 
  all 
  the 
  plants 
  that 
  

   have 
  been 
  found 
  on 
  these 
  islands 
  since 
  their 
  discovery 
  in 
  1786 
  is 
  

   given 
  in 
  the 
  present 
  paper, 
  the 
  total 
  number 
  of 
  Phanerogams 
  

   amounting 
  to 
  172; 
  3 
  species 
  of 
  Equisetum, 
  3 
  of 
  Ly 
  'cop 
  odium 
  , 
  

   and 
  6 
  ferns 
  besides 
  a 
  number 
  of 
  mosses, 
  lichens 
  and 
  fungi, 
  are 
  

   recorded. 
  Among 
  the 
  Phanerogams 
  we 
  notice 
  several 
  species 
  as 
  

   being 
  circumpolar, 
  for 
  instance 
  : 
  JSaxifraga 
  stellaris 
  var. 
  comosa, 
  

   Chrysosplenium 
  alter 
  mifolium, 
  Eutrema 
  Edwardsii, 
  Hippuris 
  

   vulgaris, 
  Koenigia 
  islandica, 
  etc., 
  the 
  last 
  being 
  the 
  only 
  annual 
  

   species. 
  Papaver 
  Macounii, 
  Cardamine 
  umbellata, 
  Chrysos- 
  

   p>lenium 
  JBeringianum, 
  Primida 
  Macounii, 
  P. 
  eximia. 
  Poly- 
  

   gonum 
  Macounii, 
  Elymus 
  villosissimus 
  and 
  Carex 
  Pribilovensis 
  

   are 
  described 
  as 
  new, 
  and 
  the 
  first 
  six 
  are, 
  furthermore, 
  figured. 
  

   The 
  paper 
  constitutes 
  a 
  very 
  important 
  contribution 
  to 
  the 
  knowl- 
  

   edge 
  of 
  this 
  flora, 
  and 
  it 
  may 
  be 
  stated 
  that 
  the 
  author 
  has 
  per- 
  

   sonally 
  examined 
  all 
  the 
  species 
  included 
  in 
  the
