  collected 
  along

  The 
  lobation 
  of 
  the 
  leaves 
  of 
  this 
  species 
  differs 
  materially 
  from 
  that 
  of 
  

   its 
  nearest 
  allies. 
  The 
  arrangement 
  and 
  appearance 
  of 
  the 
  coronae 
  suggest 
  

   P. 
  hiflora, 
  but 
  the 
  flower 
  is 
  larger, 
  the 
  petals 
  are 
  rose-colored, 
  and 
  the 
  leaves 
  

   are 
  distinctly 
  3-lobed, 
  the 
  middle 
  lobe 
  generally 
  being 
  slightly 
  the 
  largest.
