  In 
  addition 
  to 
  the

  specimens 
  from 
  Espiritu 
  Santo, 
  Magdalena 
  Island, 
  

   and

  have 
  been

  Its 
  shrubby 
  aspect 
  and 
  ex- 
  

   treme 
  oiliness, 
  resulting 
  from 
  numerous 
  gland-tipped 
  hairs, 
  distinguish 
  this 
  

   species 
  from 
  Passiflora 
  arida, 
  while 
  its 
  smaller 
  flowers, 
  its 
  proportionately 
  

   broader 
  petals, 
  and 
  longer 
  faucial 
  corona 
  threads 
  differentiate 
  it
