  But 
  one 
  specimen 
  of 
  this 
  species 
  has 
  been 
  examined 
  and 
  upon 
  this 
  no 
  

   bracts 
  were 
  present. 
  In 
  other 
  respects 
  it 
  bears 
  a 
  strong 
  resemblance 
  to 
  P. 
  

   hahnii 
  and 
  it 
  is 
  to 
  be 
  suspected 
  that 
  it 
  has 
  foliaceous 
  deciduous 
  bracts. 
  It 
  

   ma}^ 
  be 
  distinguished 
  from 
  P. 
  hahnii 
  by 
  its 
  larger, 
  crenate 
  stipules, 
  the 
  glau- 
  

   cous 
  under 
  surface 
  of 
  the 
  leaves, 
  and 
  its 
  smaller 
  flowers. 
  From 
  P. 
  meni- 
  

   hranacea, 
  another 
  species 
  of 
  this 
  group, 
  it 
  differs 
  in 
  its 
  spreading 
  sepals 
  and 
  

   petals, 
  its 
  shorter 
  peduncles, 
  and 
  in 
  the 
  elongate 
  middle 
  lobe 
  of 
  its 
  leaves.

  This 
  species 
  is 
  to 
  be 
  distinguished 
  from 
  Passiflora 
  capsularis 
  by 
  the 
  shape 
  

   of 
  the 
  leaves 
  and 
  the 
  character 
  of 
  the 
  faucial 
  corona. 
  In 
  P. 
  costaricensis 
  

   the 
  leaves 
  are 
  longer 
  than 
  broad 
  and 
  are 
  rounded 
  at 
  the 
  base; 
  they 
  have 
  a 
  

   semicircular 
  sinus, 
  formed 
  by 
  relatively 
  approximate 
  lobes.

  P.
