  When 
  described 
  by 
  Boeckeler 
  in 
  Linnsea, 
  37, 
  p.

  this 
  

   species 
  was 
  imperfectly 
  known, 
  as 
  this 
  author 
  had 
  seen 
  only 
  

   an 
  nnripe 
  specimen. 
  I 
  have 
  therefore 
  drawn 
  in 
  the 
  plate

   a 
  specimen 
  from 
  Måtto

  showing 
  a 
  flowering 
  spikelet 
  

   and 
  the 
  ripe 
  nut:
