  the 
  collector 
  states 
  that 
  the 
  leaves 
  are 
  7-lobed. 
  The 
  two 
  leaves 
  which 
  

   the 
  specimen 
  bears 
  are 
  but 
  5-lobed. 
  Doubtless 
  the 
  lower 
  leaves 
  have 
  an 
  

   additional 
  pair 
  of 
  lobes.

  Type 
  in 
  the 
  U. 
  S. 
  National 
  Herbarium, 
  no. 
  1,060,000, 
  cultivated 
  in 
  vol- 
  

   canic 
  loam 
  at 
  Banos, 
  Tungurahua, 
  Ecuador, 
  at 
  an 
  altitude 
  of 
  1,850 
  meters, 
  

   collected 
  March 
  6, 
  1921, 
  by 
  Wilson 
  Popenoe 
  (no. 
  1271). 
  

  

  The 
  nearest 
  relative 
  of 
  P. 
  popenovii 
  is 
  P. 
  laurifolia, 
  widely 
  cultivated 
  in 
  

   the 
  West 
  Indies 
  under 
  the 
  name 
  water-lemon. 
  The 
  flowers 
  of 
  the 
  two 
  species 
  

   are 
  very 
  much 
  alike, 
  the 
  coronal 
  structure 
  being 
  practically 
  identical. 
  Passi- 
  

   flora 
  popenovii 
  is 
  to 
  be 
  separated, 
  however, 
  by 
  its 
  thinner, 
  more 
  acuminate 
  

   leaves, 
  by 
  the 
  absence 
  of 
  petiolar 
  glands, 
  and 
  by 
  its 
  more 
  slender 
  and 
  more 
  

   elongate 
  peduncles. 
  

  

  This 
  species 
  is 
  one 
  of 
  several 
  cultivated 
  in 
  Ecuador 
  under 
  the 
  name 
  of 
  

   "Granadilla 
  de 
  Quijos" 
  and 
  the 
  edible 
  fruit 
  is 
  commonly 
  on 
  sale 
  in 
  the 
  markets 
  

   of 
  Banos 
  and 
  Riobamba. 
  It 
  is 
  said 
  to 
  be 
  indigenous 
  on 
  the 
  eastern 
  slopes 
  

   of 
  the 
  Andes.
