  COLLECTIONS 
  TOWARDS 
  

  

  a 
  little 
  crenulated 
  along 
  the 
  margin 
  in 
  common 
  with 
  the 
  lip, 
  and 
  both 
  

   of 
  a 
  yellowish 
  green 
  colour; 
  spur 
  curving 
  upwards, 
  a 
  little 
  thicker 
  

   towards 
  the 
  base, 
  and 
  scarcely 
  the 
  length 
  of 
  the 
  germ 
  ; 
  the 
  lip 
  some- 
  

   what 
  longer 
  than 
  the 
  lateral 
  segments, 
  partly 
  oblong-oval, 
  emarginate 
  

   at 
  the 
  extremity, 
  and 
  at 
  its 
  commencement 
  producing 
  a 
  denture 
  on 
  

   either 
  side, 
  and 
  one 
  protuberant 
  or 
  central 
  elevation. 
  — 
  Obs. 
  In 
  this 
  

   species 
  the 
  lip 
  is 
  much 
  the 
  broadest 
  portion 
  of 
  the 
  corolla, 
  and 
  the 
  

   widest 
  at 
  its 
  base, 
  from 
  which, 
  as 
  well 
  as 
  the 
  two 
  leaves 
  upon 
  the 
  stem, 
  

   and 
  its 
  uneven 
  margin, 
  it 
  is 
  readily 
  distinguishable 
  from 
  O. 
  tridentata, 
  

   but 
  approaches 
  O. 
  fuscescens, 
  and 
  cannot 
  be 
  O. 
  clavellata 
  of 
  Michaux, 
  

   which 
  in 
  several 
  characters 
  agrees 
  nearly 
  with 
  O. 
  tridentata. 
  The 
  

   name 
  I 
  have 
  employed, 
  is 
  in 
  reference 
  to 
  the 
  form 
  of 
  the 
  lip, 
  which 
  is 
  

   very 
  much 
  like 
  that 
  of 
  an 
  armorial 
  shield.
