  the 
  following 
  species 
  

   are 
  mentioned 
  as 
  pertaining

  this

  : 
  C. 
  glaucescens 
  

   Ell., 
  phacota

  Arnottiana

  and 
  salina

  Several 
  other 
  species 
  may 
  be 
  added,

  and 
  the 
  grex 
  

   comprises 
  about 
  forty 
  species 
  in 
  all. 
  

  

  No 
  li

  are 
  known 
  of 
  this 
  grex; 
  all 
  the 
  

   species 
  have 
  the 
  spikes 
  well 
  differentiated, 
  and 
  among 
  

   the 
  most 
  evolute 
  species 
  we 
  meet 
  with 
  such 
  types 
  as 
  the 
  

   polystachyous

  C.

  Boott, 
  and 
  C.

   Boott, 
  in 
  which 
  the 
  inflorescence 
  is 
  very 
  ample, 
  decom- 
  

   pound, 
  with 
  several 
  (2 
  to 
  3) 
  spikes 
  proceeding 
  from 
  the 
  

   axils 
  of 
  the 
  leafy 
  bracts. 
  In 
  some 
  species 
  the 
  terminal 
  

   spike 
  is 
  gynaecandrous 
  :

  sometimes

  Boott, 
  and 
  C. 
  phacota 
  Sprgi. 
  In 
  C. 
  Magellanica 
  

   Lam. 
  the 
  lateral 
  spikes 
  are 
  constantly, 
  the 
  terminal 
  fre- 
  

   quently 
  gynaecandrous. 
  Otherwise 
  the 
  species 
  show 
  the 
  

   general 
  habit 
  with 
  the 
  terminal 
  spike 
  staminate, 
  the 
  

   lateral 
  pistillate 
  or 
  not 
  infrequently 
  androgynous 
  (C. 
  

   salina 
  Wahlenb., 
  C. 
  cryptocarpa 
  C. 
  A. 
  Mey., 
  G. 
  aperta 
  

   Boott 
  etc.). 
  Most 
  frequently 
  the 
  spikes 
  are 
  borne 
  on 
  

   long 
  peduncles, 
  and 
  drooping, 
  and 
  the 
  subtending 
  bracts 
  

   are 
  generally 
  long 
  and 
  foliaceous, 
  but 
  not 
  sheathing. 
  

   The 
  color 
  of 
  the 
  pistillate 
  spikes 
  varies 
  from 
  green 
  to 
  

   light 
  brown 
  or 
  dark 
  purplish 
  ;

  scales 
  of 
  the 
  pistillate
