  Oreocarya 
  procera 
  sp. 
  nov. 
  

  

  A 
  biennial 
  or 
  short-lived 
  perennial, 
  stem 
  3-4 
  dm. 
  high 
  from 
  a 
  

   tap 
  root, 
  single 
  or 
  usually 
  with 
  some 
  shorter 
  stems 
  from 
  the 
  base, 
  

   green 
  but 
  hispid 
  with 
  horizontal, 
  stiff, 
  white 
  bristles, 
  though 
  not 
  

   densely 
  so, 
  and 
  thinly 
  covered 
  beneath 
  with 
  short 
  reflexed 
  hairs; 
  

   the 
  lowest 
  leaves 
  spatulate, 
  including 
  the 
  slender 
  petiole 
  about 
  

  

  5 
  cm. 
  long, 
  stem 
  leaves 
  oblanceolate, 
  the 
  middle 
  ones 
  4-5 
  cm. 
  

   long 
  including 
  the 
  short 
  petiole, 
  and 
  3-10 
  mm. 
  wide, 
  densely 
  

   pubescent 
  on 
  both 
  sides 
  with 
  short 
  close 
  pubescense, 
  and 
  the 
  

   lower 
  side 
  with 
  stiff 
  bristles, 
  and 
  the 
  edges 
  beset 
  with 
  stout 
  

   bristles; 
  fioriferous 
  from 
  near 
  the 
  base, 
  the 
  flowers 
  on 
  short 
  

   axillary 
  branches, 
  in 
  somewhat 
  capitate 
  clusters 
  which 
  lengthen 
  

   in 
  fruit, 
  alternate, 
  and 
  on 
  some 
  of 
  the 
  stems 
  scarcely 
  overlapping 
  

   till 
  near 
  the 
  top; 
  the 
  calyx 
  lobes 
  lanceolate, 
  4 
  mm. 
  long, 
  becoming 
  

  

  6 
  mm. 
  in 
  fruit, 
  bristly; 
  the 
  corolla 
  3 
  mm. 
  long, 
  the 
  limb 
  5-6 
  mm. 
  

   wide, 
  the 
  throat 
  crested, 
  the 
  anthers 
  included, 
  filaments 
  very 
  

   short; 
  nutlets 
  four, 
  ovate, 
  when 
  mature 
  about 
  3.5 
  mm. 
  long, 
  

   rather 
  more 
  than 
  2 
  mm. 
  wide, 
  margined, 
  but 
  not 
  winged, 
  bluntly 
  

   tuberculate 
  on 
  the 
  back, 
  the 
  tubercles 
  more 
  prominent 
  on 
  the 
  

   slight 
  middle 
  ridge. 
  

  

  The 
  only 
  locality 
  from 
  which 
  I 
  have 
  Oreocarya 
  procera 
  is 
  

   Glenwood 
  Springs, 
  Garfield 
  County, 
  Colorado, 
  where 
  I 
  have 
  

   collected 
  it 
  on 
  four 
  different 
  dates, 
  and 
  as 
  I 
  remember, 
  in 
  stony 
  soil 
  

   along 
  the 
  Grand 
  River. 
  ^The 
  first 
  collection 
  was 
  on 
  July 
  I, 
  

   1895. 
  For 
  the 
  type 
  specimen 
  I 
  have 
  chosen 
  No. 
  1867, 
  collected 
  

   June 
  18, 
  1899. 
  Oreocarya 
  procera 
  is 
  tall 
  and 
  remotely 
  leafy 
  for 
  

   an 
  Oreocarya, 
  and 
  not 
  so 
  densely 
  hispid 
  as 
  many 
  of 
  them. 
  The 
  

   somewhat 
  immature 
  nutlets 
  appear 
  to 
  be 
  narrowly 
  winged, 
  but 
  

   the 
  mature 
  nutlets 
  are 
  only 
  margined. 
  It 
  does 
  not 
  closely 
  resemble 
  

   any 
  Oreocarya 
  with 
  which 
  I 
  am 
  acquainted, 
  but 
  has 
  a 
  slight 
  resem- 
  

   blance 
  to 
  Oreocarya 
  affinis 
  Greene.
