  The 
  grex 
  is 
  thus 
  a 
  very 
  complete 
  one, 
  represented 
  by 
  

   dioecious 
  and 
  monoecious 
  hebetated, 
  passing 
  through 
  the 
  

   singular 
  C. 
  curvula 
  to 
  the 
  centrales; 
  most 
  of 
  these 
  show 
  

   the 
  ordinary 
  habit 
  with 
  the 
  terminal 
  spike 
  staminate, 
  

   and 
  the 
  lateral 
  pistillate 
  ; 
  at 
  the 
  end 
  of 
  the 
  centrales 
  are 
  

   some 
  few 
  species 
  with 
  the 
  terminal 
  spike 
  gynaecandrous, 
  

   passing 
  into 
  the 
  peculiar 
  species 
  C. 
  petricosa 
  and 
  C. 
  

   Franklinii. 
  Among 
  the 
  desciscentes 
  C. 
  macrogyna 
  with 
  

   the 
  spikes 
  androgynous, 
  but 
  single, 
  passes 
  into 
  the 
  most 
  

   evolute 
  types 
  of 
  the 
  grex 
  C. 
  teinogyna, 
  G. 
  longicruris, 
  

   and 
  C. 
  insignis 
  with 
  the 
  androgynous 
  spikes 
  fasciculate 
  ; 
  

   of 
  these 
  the 
  two 
  former 
  are 
  distigmatic 
  with 
  the 
  beak 
  of 
  

   utriculus 
  distinctly 
  bidentate, 
  while 
  C. 
  insignis 
  is 
  tristig- 
  

   matic 
  with 
  the 
  beak 
  entire. 
  A 
  bidentate 
  beak 
  is 
  also 
  

   characteristic 
  of 
  several 
  of 
  the 
  centrales,
