   slightly

  Found 
  at 
  Cisco, 
  C. 
  P. 
  E. 
  R., 
  Sierra 
  Nevada 
  mountains, 
  iu 
  January, 
  1870, 
  

   by 
  Kellogg 
  and 
  Brannan. 
  

  

  This 
  Bahia 
  seems 
  nearest 
  allied 
  to 
  an 
  unknown 
  or 
  not 
  sufficiently 
  verified 
  

   species, 
  described 
  by 
  Nuttall, 
  the 
  B. 
  oppositifolia. 
  We 
  have 
  not 
  been 
  able 
  to 
  

   ascertain 
  whether 
  this 
  is 
  an 
  annual 
  or 
  perennial 
  — 
  this 
  point 
  of 
  comparison, 
  

   therefore, 
  must 
  be 
  waived. 
  In 
  this 
  specimen, 
  out 
  of 
  several 
  hundred 
  leaves, 
  we 
  

   find 
  only 
  two 
  " 
  palmately 
  trilobed," 
  and 
  in 
  these, 
  the 
  lobes 
  are 
  not 
  " 
  obtuse," 
  

   '■ 
  ligulate," 
  etc., 
  but 
  lanceolate, 
  and 
  the 
  middle 
  lobe 
  of 
  one, 
  dentate, 
  as 
  iu 
  the 
  

   normal 
  foliage 
  ; 
  the 
  peduncles 
  are 
  not 
  " 
  filiform," 
  nor 
  " 
  scarcely 
  longer 
  than 
  the 
  

   leaves," 
  the 
  involucre 
  of 
  our 
  plant 
  is 
  not 
  even 
  cylindrical, 
  much 
  less 
  " 
  oblong 
  

   cylindrical," 
  nor 
  are 
  the 
  rays 
  "very 
  short" 
  ; 
  these 
  heads 
  are 
  strictly 
  campanu- 
  

   late, 
  as 
  we 
  approach 
  the 
  central 
  and 
  more 
  perfect 
  parts, 
  the 
  minute 
  chaff 
  of 
  the 
  

   seed 
  is 
  exceedingly 
  lacei-ate 
  and 
  acute; 
  finally, 
  the 
  plant 
  has 
  no 
  special 
  bitter- 
  

   ■neps, 
  to 
  speak 
  of. 
  I 
  have 
  not 
  been 
  able 
  to 
  find 
  any 
  other 
  species 
  that 
  so 
  nearly 
  

   approaches 
  ii 
  as 
  this, 
  that 
  would 
  seem 
  to 
  require 
  a 
  further 
  comparison. 
  

  

  ■Crepis 
  occidentalis, 
  var. 
  subacaulis, 
  Kellogg. 
  

  

  Leaves 
  chiefly 
  radicle, 
  about 
  the 
  length 
  of 
  the 
  perennial 
  scapoid 
  stem 
  (3 
  to 
  4 
  

   inches 
  high), 
  simple 
  (?) 
  hirsute 
  with 
  scattering 
  hairs, 
  and 
  short 
  canesceut 
  pu- 
  

   bescence, 
  bearing 
  a 
  single 
  head 
  ; 
  leaves 
  deeply 
  pinnatifid, 
  lobes 
  toothed, 
  points 
  

   itipped 
  with 
  short, 
  sharp, 
  subspinous, 
  corneous 
  mucros, 
  petioles 
  about 
  i^ 
  the 
  

   length 
  of 
  the 
  blade, 
  }4 
  cauline, 
  the 
  uppermost 
  a 
  sessile 
  rudiment 
  ; 
  involucre 
  of 
  

   6 
  or 
  7 
  short, 
  calyculate, 
  appressed, 
  lance-subulate 
  scales, 
  interior 
  of 
  13 
  linear- 
  

   lanceolate 
  acuminate 
  scales, 
  margins 
  scarious, 
  nerved, 
  canescent 
  pubescent, 
  tips 
  

   hirsute 
  ; 
  receptacle 
  subalveolate 
  chiefly 
  at 
  the 
  margin 
  ; 
  achenia 
  9 
  to 
  10-ribbed, 
  

   tapering 
  about 
  equally 
  to 
  both 
  ends, 
  scarcely 
  a 
  little 
  constricted 
  or 
  subrostrate, 
  

   base 
  slightly 
  callous, 
  outer 
  fertile 
  achenia 
  about 
  equal 
  to 
  the 
  pappus, 
  inner 
  cen- 
  

   tral 
  shorter. 
  

  

  Found 
  on 
  the 
  high 
  peaks 
  at 
  Cisco, 
  C. 
  P. 
  R. 
  E., 
  Sierra 
  Nevada 
  mountains, 
  

   about 
  7,000 
  feet, 
  June 
  27th, 
  1870, 
  by 
  Mr, 
  S. 
  Brannan, 
  Jr., 
  and 
  myself. 
  

  

  This 
  may 
  prove 
  to 
  be 
  a 
  var. 
  of 
  Nevadensis, 
  mostly 
  with 
  fewer 
  parts 
  and 
  de- 
  

   pauperate 
  influences, 
  owing 
  to 
  habitat.
