  In 
  the 
  shape 
  of 
  its 
  leaves 
  and 
  the 
  size 
  of 
  its 
  seeds 
  this 
  species 
  resembles 
  P. 
  

   exsvidans 
  Zucc. 
  It 
  is 
  readily 
  distinguished 
  .by 
  the 
  location 
  of 
  the 
  petiolar 
  

   glands 
  at 
  the 
  apex 
  of 
  the 
  petioles 
  and 
  by 
  its 
  densely 
  hispidulous, 
  glaucous 
  

   fruit.
