  Passiflora 
  williamsii 
  belongs 
  to 
  the 
  group 
  of 
  the 
  subgenus 
  Granadilla 
  which 
  

   is 
  characterized 
  by 
  partially 
  united 
  bracts. 
  From 
  P. 
  seemanni, 
  P. 
  platyloha, 
  

   and 
  P. 
  ligularis, 
  the 
  other 
  representatives 
  of 
  this 
  group, 
  it 
  is 
  readily 
  distin- 
  

   guished 
  by 
  its 
  leaves, 
  which 
  are 
  truncate 
  or 
  very 
  shallowly 
  cordate 
  at 
  base 
  

   and 
  densely 
  puberulent 
  beneath. 
  In 
  the 
  three 
  other 
  species 
  the 
  leaves 
  are 
  

   deeply 
  cordate 
  and 
  entirely 
  glabrous.
