  from 
  which 
  it 
  can 
  be 
  distinguished 
  by 
  its 
  longer 
  leaves 
  and 
  by 
  the 
  inflorescence. 
  

   Its 
  peduncles 
  are 
  borne 
  in 
  pairs 
  on 
  short, 
  axillary 
  branches, 
  rather 
  than 
  

   singly 
  in 
  the 
  axils 
  of 
  the 
  leaves 
  of 
  the 
  main 
  stem.

  Type 
  in 
  the 
  U. 
  S. 
  National 
  Herbarium, 
  no. 
  941,000, 
  collected 
  in 
  forests 
  at 
  

   Xirores, 
  Talamanca, 
  Costa 
  Rica, 
  at 
  an 
  altitude 
  of

  meters,

  In 
  texture 
  the 
  foliage 
  of 
  this 
  species 
  resembles 
  that 
  of 
  Passiflora 
  trisetosa. 
  

   The 
  leaves, 
  however, 
  are 
  larger 
  and 
  more 
  elongate, 
  and 
  the 
  central 
  lobe 
  is 
  

   much 
  more 
  prominent. 
  The 
  flowers 
  of 
  the 
  two 
  species 
  present 
  certain 
  im- 
  

   portant 
  differences. 
  P. 
  talamancensis 
  has 
  a 
  2-ranked 
  faucial 
  corona, 
  an 
  

   erect 
  middle 
  corona, 
  and 
  a 
  globose, 
  softly 
  tomentellous 
  ovary. 
  Passi- 
  

   flora 
  trisetosa 
  has 
  a 
  single-ranked 
  faucial 
  corona, 
  an 
  incurved 
  middle 
  corona, 
  

   and 
  an 
  ovoid, 
  strigillose 
  ovary.
