  margins 
  ciliate 
  at 
  the 
  base 
  or 
  origin 
  of 
  the 
  claw 
  ; 
  keel 
  ciliate 
  at 
  the 
  upper 
  in- 
  

   side 
  margin 
  toward 
  the 
  base, 
  acute. 
  Legume 
  very 
  hirsute, 
  2-seeded. 
  

  

  In 
  habit 
  and 
  general 
  appearance 
  this 
  species 
  resembles 
  L. 
  brevicaulis, 
  but 
  is 
  

   rather 
  more 
  robust, 
  the 
  flowers 
  much 
  larger 
  and 
  not 
  " 
  deep 
  blue," 
  but 
  quite 
  

   white 
  ; 
  besides, 
  the 
  truncate 
  upper 
  lip 
  is 
  a 
  peculiar 
  distinguishing 
  feature 
  of 
  

   that 
  species 
  — 
  that 
  has 
  bracteoles 
  on 
  calyx, 
  this 
  none, 
  etc. 
  It 
  is 
  closely 
  allied 
  

   to 
  L. 
  Menziesii, 
  but 
  the 
  relatively 
  shorter 
  pedicels, 
  and 
  much 
  longer 
  peti- 
  

   oles, 
  and 
  both 
  lips 
  lacking 
  the 
  " 
  entire" 
  character 
  and 
  relative 
  proportion, 
  

   would 
  strongly 
  tend 
  to 
  exclude 
  it 
  ; 
  admitting 
  L. 
  densiflorus 
  to 
  be 
  the 
  same 
  as 
  

   L. 
  Menziesii, 
  "with 
  variations," 
  it 
  would 
  then 
  bring 
  us 
  a 
  "dense,, 
  sub- 
  

   sessile 
  spike," 
  an 
  emarginate 
  upper 
  lip, 
  and 
  3-toothed 
  lower 
  one, 
  with 
  

   which 
  to 
  contend. 
  If 
  these 
  and 
  many 
  more 
  varieties 
  prove 
  ultimately 
  to 
  run 
  

   into 
  one, 
  it 
  is 
  not 
  our 
  fault 
  ; 
  as 
  the 
  literature 
  now 
  stands, 
  we 
  are 
  obliged, 
  in 
  

   self-defence, 
  to 
  set 
  it 
  apart, 
  when 
  called 
  upon 
  for 
  determinations. 
  Specimens 
  

   collected 
  by 
  Mr. 
  S. 
  Brannan, 
  Jr., 
  on 
  Oak 
  Creek 
  hillsides, 
  Kern 
  county, 
  14

  Tejon 
  Pass. 
  

  

  Lupinus 
  luteolus,

  high, 
  sufFruticose, 
  glabrous 
  below, 
  bark 
  light 
  creamy 
  hue, 
  sat- 
  

   iny 
  fibrous 
  ; 
  minutely 
  pubescent 
  above, 
  upright, 
  flexuous 
  and 
  numerously 
  

   branched 
  towards 
  the 
  top, 
  forming 
  a 
  very 
  symmetrical, 
  rather 
  wheel-shaped 
  

   cone 
  ; 
  clothed 
  with 
  minute 
  villi 
  of 
  white 
  hairs. 
  Leaflets

  8, 
  oblanceolate, 
  

   abruptly 
  acute, 
  attenuate 
  at 
  base, 
  about 
  X 
  the 
  length 
  of 
  the 
  petiole, 
  silky 
  

   above 
  and 
  below 
  ; 
  stipules 
  setaceous, 
  i^ 
  of 
  an 
  inch 
  or 
  more 
  in 
  length, 
  adnate 
  

   pubescent 
  with 
  longer 
  hairs. 
  Flowers 
  light 
  yellow, 
  verticillate 
  on 
  short, 
  stout 
  

   pedicels, 
  in 
  a 
  densely 
  crowded 
  spike

  to 
  12 
  inches 
  in 
  length, 
  the 
  central 
  termi- 
  

   nal 
  one 
  straight 
  and 
  longest, 
  those 
  of 
  the 
  branches 
  slightly 
  incurved 
  ; 
  bracts 
  

   persistent, 
  subulate, 
  silky 
  pubescent, 
  mostly 
  somewhat 
  reflexed 
  with 
  the 
  points 
  

   ascending, 
  as 
  long, 
  or 
  extended 
  beyond 
  the 
  lower 
  lip 
  of 
  the 
  calyx 
  ; 
  calyx-tube 
  

   scarious, 
  very 
  short 
  and 
  widely 
  gaping, 
  2-bracteolate, 
  bracts 
  setaceous, 
  % 
  the 
  

   length 
  of 
  the 
  upper 
  lip 
  ; 
  upper 
  lip 
  ovate-lanceolate 
  acute 
  entire 
  ; 
  lower 
  lip 
  herb- 
  

   aceous, 
  3-toothed, 
  slightly 
  deflexed 
  and 
  sub-saccated 
  at 
  the 
  junction 
  of 
  the 
  scar- 
  

   ious 
  portion, 
  hirsute 
  throughout.

  somewhat 
  

   inflated, 
  glabrous, 
  with 
  scarcely 
  a 
  few 
  hairs 
  on 
  the 
  margins 
  at 
  the 
  base 
  ; 
  keel 
  

   acute 
  villous 
  on 
  the 
  margins 
  above 
  at 
  the 
  lower 
  third. 
  Legumes 
  very 
  villous, 
  

   2-seeded. 
  

  

  Found 
  on 
  the 
  Coast 
  range 
  of 
  mountains, 
  near 
  Senal, 
  Mendocino 
  County, 
  

   Cal., 
  1872. 
  

  

  This 
  species 
  does 
  not 
  seem 
  likely 
  to 
  be 
  confounded 
  with 
  any 
  other 
  in 
  Califor- 
  

   nia. 
  Few 
  species 
  in 
  the 
  genus 
  have 
  the 
  entire 
  upper 
  lip. 
  Donn 
  describes 
  L. 
  Sa- 
  

   binii 
  (a 
  yellow 
  Lupin 
  of 
  similar 
  habit) 
  thus: 
  But 
  that 
  is 
  described 
  by 
  all 
  

   authors 
  accessible 
  to 
  me, 
  as 
  without 
  bracteoles 
  to 
  the 
  calyx. 
  Hooker 
  says 
  that 
  

   has 
  ';' 
  acuminate 
  " 
  leaflets 
  — 
  yellow 
  silkiness, 
  and 
  that 
  the 
  bracts 
  are 
  " 
  deciduous," 
  

   whereas, 
  these 
  are 
  persistent 
  ; 
  nor 
  has 
  our 
  plant 
  the 
  upper 
  lip 
  " 
  b/Jied," 
  as 
  some 
  

   describe 
  it 
  ; 
  besides, 
  this 
  is 
  2-bracteolate, 
  a 
  fact 
  that 
  cannot 
  be 
  overlooked 
  ; 
  nor
