  The 
  second 
  species 
  of 
  the 
  

   genus. 
  This 
  and 
  the 
  three 
  preceding 
  are 
  the 
  only 
  ones 
  

   which 
  possess 
  the 
  thick 
  callous 
  margin 
  of 
  the 
  akenes. 
  Gray 
  

   (:!5yn. 
  l^lora) 
  describes 
  the 
  akenes 
  as 
  follows 
  : 
  "Akenes 
  ob- 
  

   ovate 
  or 
  obovate-oblong, 
  with 
  broad 
  summit, 
  villous-ciliate 
  

   margins, 
  and 
  a 
  pair 
  of 
  delicate 
  awns, 
  which 
  barely 
  equal 
  the 
  

   breadth 
  of 
  the 
  akene, 
  and 
  are 
  twice 
  or 
  thrice 
  the 
  length 
  of 
  

   the 
  crown 
  of 
  squamellae. 
  The 
  awn 
  under 
  high 
  power 
  is 
  a 
  

   little 
  scabrous 
  ; 
  akene 
  f 
  line 
  long 
  (ftg. 
  5). 
  

  

  It 
  differs 
  from 
  P. 
  Californica 
  in 
  the 
  length 
  and 
  the 
  character 
  of 
  the 
  

   awns, 
  and 
  the 
  .horter 
  crown.
