  For 
  some 
  time 
  past 
  the 
  writer 
  has 
  been 
  engaged 
  in 
  a 
  study 
  of 
  the 
  

   tropical 
  North 
  American 
  species 
  of 
  Passiflora, 
  with 
  particular 
  reference 
  

   to 
  Mexico 
  and 
  Central 
  America, 
  a 
  region 
  from 
  which 
  few 
  species 
  have 
  

   been 
  described 
  since 
  Master's 
  comprehensive 
  revision 
  of 
  the 
  American 
  

   species 
  in 
  1872. 
  Since 
  the 
  publication 
  of 
  final 
  results 
  is 
  unavoidably 
  

   delayed, 
  it 
  seems 
  advisable 
  to 
  publish 
  in 
  advance 
  descriptions 
  of 
  cer- 
  

   tain 
  of 
  the 
  new 
  species, 
  in 
  order 
  that 
  the 
  names 
  may 
  be 
  available.

  The

  resembles 
  that

  certain 
  species 
  of

  section 
  

   Decaloha 
  with 
  bilobate 
  leaves, 
  notable 
  Passiflora 
  ornithoura, 
  and 
  is 
  unlike 
  

   that 
  of 
  most 
  of 
  its 
  apetalous 
  allies. 
  From

  ornithoura 
  it
