  — 
  Obs. 
  Probably 
  the 
  largest 
  species 
  in 
  the 
  United 
  States 
  ; 
  

   the 
  stem 
  being 
  from 
  eighteen 
  inches 
  to 
  two 
  and 
  a 
  half 
  feet 
  high; 
  

   leaves 
  oblong-lanceolate, 
  diminishing 
  into 
  narrow 
  lanceolate 
  bracts, 
  

   about 
  the 
  length 
  of 
  the 
  germ 
  ; 
  flowers 
  white, 
  a 
  little 
  tinged 
  with 
  green 
  ; 
  

   the 
  lateral 
  segments 
  of 
  the 
  petaloid 
  calix 
  ovate, 
  and 
  less 
  than 
  half 
  the 
  

   length 
  of 
  the 
  lip, 
  which 
  is 
  divided 
  into 
  three 
  dilated 
  segments, 
  divided 
  

   nearly 
  to 
  the 
  base 
  into 
  many 
  capillary 
  portions. 
  It 
  is 
  more 
  nearly 
  

   allied 
  to 
  O. 
  incisa 
  than 
  psyeodes, 
  but 
  differs 
  from 
  the 
  former 
  in 
  the 
  

   laciniated 
  lip, 
  and 
  from 
  the 
  latter 
  by 
  the 
  multiplicity 
  of 
  its 
  segments, 
  

   and 
  the 
  obovate, 
  instead 
  of 
  linear 
  form 
  of 
  the 
  two 
  internal 
  petaloid 
  

   divisions.

  O. 
  *scutellata. 
  Labello 
  subovali-oblongo, 
  emarginato, 
  basi 
  utrinque 
  

   ad 
  medium 
  dentato, 
  cornu 
  filiformi 
  vix 
  longitudine 
  germinis 
  ; 
  floribus 
  

   sparsis;
