  botanists 
  in 
  Scandinavia, 
  who 
  were 
  familiar 
  with 
  the 
  

   plant 
  through 
  observations 
  in 
  the 
  field, 
  or 
  by 
  means 
  of 
  

   the 
  copious 
  material 
  brought 
  together 
  and 
  deposited 
  in 
  

   the 
  Museums 
  of 
  these 
  countries. 
  However, 
  while 
  the 
  

   aim 
  of 
  the 
  classification 
  was 
  the 
  same, 
  to 
  demonstrate 
  the 
  

   mutual 
  affinities 
  of 
  the 
  various 
  types 
  represented 
  by 
  this 
  

   species, 
  it 
  is 
  to 
  be 
  regretted, 
  that 
  some 
  authors 
  have 
  

   deemed 
  it 
  necessary 
  to 
  include 
  under 
  C. 
  salina 
  some 
  

   other 
  species, 
  which 
  are 
  certainly 
  not 
  conspecific: 
  C. 
  

   subspaihacea 
  Wormskj., 
  C. 
  hcematolepis 
  Drej., 
  and

  As 
  already 
  indicated 
  in 
  the 
  preceding 
  G. 
  salina 
  is 
  quite 
  

   a 
  variable 
  species, 
  containing 
  about 
  ten 
  varieties 
  and 
  

   forms, 
  all 
  of 
  which 
  are 
  well 
  marked, 
  and 
  readily 
  to 
  be 
  

   distinguished 
  from 
  the 
  species 
  mentioned 
  above. 
  

  

  Typical 
  G. 
  salina 
  (Figs. 
  1-4) 
  may 
  be 
  described 
  as 
  fol- 
  

   lows: 
  

  

  Ehizome 
  loosely 
  csespitose 
  to 
  stolonif 
  erous 
  ; 
  leaves 
  

   yellowish

  erect, 
  flat, 
  about 
  3-4 
  mm. 
  broad, 
  as 
  long 
  

   as 
  the 
  culms 
  or 
  a 
  little 
  longer; 
  culms 
  erect, 
  about 
  10-25 
  

   cm. 
  in 
  height, 
  triquetrous, 
  scabrous 
  or 
  almost 
  smooth; 
  

   staminate 
  spikes 
  1 
  or 
  2, 
  linear; 
  pistillate 
  spikes 
  2 
  to 
  4, 
  

   erect, 
  iy 
  2 
  to 
  2y 
  2 
  cm. 
  long, 
  of 
  a 
  yellowish 
  brown 
  color, 
  

   pedunculate, 
  the 
  uppermost 
  sometimes 
  androgynous; 
  

   the 
  bracts 
  subtending 
  the 
  pistillate 
  spikes 
  are 
  f 
  oliaceous, 
  

   reaching 
  the 
  staminate 
  spike 
  or 
  above 
  this, 
  not 
  sheath- 
  

   ing; 
  scales 
  of 
  the 
  pistillate 
  flowers 
  ovate 
  to 
  ovate-lance- 
  

   olate, 
  light 
  or 
  dark 
  brown 
  with 
  a 
  broad 
  midrib 
  (of 
  three 
  

   veins) 
  extending 
  to 
  the 
  apex 
  of 
  the 
  scale 
  or 
  beyond 
  this 
  

   as 
  a 
  mucro 
  or 
  short 
  arista; 
  perigynium 
  shorter 
  than 
  

   the

  broader, 
  obovate 
  to 
  broadly 
  ovate, 
  

   plano-convex, 
  faintly 
  veined,

  Common 
  on 
  the 
  sea-shore 
  of 
  

   Sweden 
  (Halland

  Bohuslsen), 
  along 
  the 
  entire 
  coast 
  

   of

   on 
  the 
  shores 
  of 
  the 
  White 
  Sea, 
  Northern

  It 
  

   is, 
  on 
  the 
  other 
  hand, 
  very 
  rare 
  in 
  North 
  America,

   the 
  only 
  specimens, 
  we

  By 
  Hartman 
  (1. 
  c.) 
  the 
  species 
  is 
  considered 
  the 
  most 
  

   variable 
  of 
  all 
  the 
  distigmatic, 
  and 
  it
