  scarcely 
  equal 
  to

   pappus 
  scarcely 
  a 
  little 
  thickened 
  at 
  the 
  base, 
  rigid, 
  shorter 
  than 
  the 
  acheniun; 
  

   achenia 
  very 
  minutely 
  hirsutish 
  and 
  serrulate 
  scabrous 
  upwards, 
  about 
  30,

   tubes 
  glandular, 
  peduncles 
  3 
  to 
  5, 
  1-3

  Found

  This 
  plant 
  varies 
  from 
  the 
  generic 
  description 
  of 
  Crepis, 
  for 
  the 
  inner 
  proper 
  

   scales 
  are 
  not 
  in 
  a 
  simple 
  series, 
  but 
  double 
  ; 
  this 
  is 
  unimportant 
  compared 
  with 
  

   the 
  receptacle, 
  which 
  is 
  that 
  of 
  a 
  Troximon, 
  being 
  sub-alveolate 
  ; 
  it 
  agrees 
  

   better 
  with 
  this 
  in 
  the 
  rather 
  rigid 
  pappus, 
  and 
  decidedly 
  in 
  the 
  large 
  5-crenated 
  

   or 
  lobed 
  callous 
  base 
  ; 
  but 
  then 
  the 
  pappus 
  is 
  not 
  " 
  longer," 
  but 
  shorter 
  than 
  

   the 
  achenium. 
  Yet, 
  with 
  these 
  discrepancies, 
  having 
  the 
  branching 
  habit, 
  and 
  

   persistent 
  yellow 
  flowers 
  — 
  granting 
  some 
  future 
  revision 
  of 
  the 
  generic 
  descrip- 
  

   tion 
  — 
  it 
  is 
  thought 
  properly 
  to 
  belong 
  to 
  Crepis. 
  

  

  Although 
  closely 
  allied 
  to 
  C. 
  occidentalis, 
  it 
  differs 
  in 
  not 
  having 
  " 
  sessile 
  

   cauline 
  leaves" 
  nor 
  " 
  blackish 
  hairs" 
  ; 
  besides, 
  C. 
  occidentalis 
  has 
  not 
  a 
  " 
  striate 
  

   achenia" 
  as 
  this 
  has 
  — 
  the 
  relative 
  length 
  of 
  achenia 
  and 
  pappus 
  is 
  not 
  sustained 
  

   by 
  our 
  plant 
  — 
  some 
  features 
  are 
  not 
  wholly 
  recognized 
  in 
  any 
  allied 
  genera 
  or 
  

   species 
  — 
  yet 
  as 
  this 
  C. 
  occidentalis 
  is 
  given 
  a 
  variable 
  latitude, 
  it 
  is 
  preferred 
  to 
  

   leave 
  it 
  here 
  provisionally.
