  rachis 
  strict 
  ; 
  peduncles 
  longer 
  tlian 
  the 
  leaves. 
  Flowers 
  numero-us 
  and 
  small, 
  

   purple 
  blue, 
  densely 
  set, 
  mostly 
  scattered 
  or 
  subverticillate 
  above, 
  pedicels 
  short 
  ; 
  

   bracts 
  subulate, 
  hirsute, 
  twice 
  the 
  length 
  of 
  pedicels, 
  extending 
  to 
  about 
  half 
  the 
  

   length 
  of 
  the 
  lower 
  lip, 
  persistent 
  ; 
  upper 
  lip 
  2-cleft, 
  2/ 
  the 
  length 
  of 
  the 
  usually 
  

   2-toothed 
  lower 
  lip 
  ; 
  wings 
  glabrous, 
  oblong, 
  obtuse 
  ; 
  keel 
  acute, 
  somewhat 
  

   woolly 
  ciliate, 
  chiefly 
  near 
  the 
  dark 
  purple 
  apex 
  : 
  vexillum 
  shorter 
  than 
  the 
  

   wings, 
  equalling 
  the 
  keel, 
  banner 
  shading 
  to 
  a 
  white 
  centre. 
  Legumes 
  hirsute, 
  

   2-seeded. 
  

  

  A 
  very 
  neat, 
  symmetrical 
  stool, 
  of 
  deep 
  lilac 
  blue 
  spikes 
  involved 
  in 
  dense 
  

   clustered 
  foliage 
  of 
  much 
  beauty, 
  with 
  the 
  aspect 
  of 
  an 
  annual. 
  Found 
  at 
  

   Donner 
  Lake, 
  summit 
  of 
  Sierra 
  Nevada 
  mountains, 
  California, 
  July 
  14th, 
  1870. 
  

  

  This 
  cannot 
  be 
  L. 
  lepidus, 
  for 
  that 
  is 
  herbaceous, 
  without 
  bracteoles, 
  nor 
  do 
  

   the 
  lips 
  agree. 
  It 
  would 
  seem 
  nearer 
  L. 
  meioimntJius, 
  Gray., 
  found 
  about 
  the 
  

   same 
  altitude 
  (7,000 
  feet), 
  and 
  near 
  the 
  same 
  region 
  ; 
  but 
  that 
  has 
  obtuse 
  leaf- 
  

   let, 
  and 
  the 
  calyx 
  is 
  without 
  bracteoles 
  — 
  lips 
  " 
  nearly 
  entire," 
  while 
  these 
  are 
  

   for 
  the 
  most 
  part 
  conspicuously 
  cleft 
  or 
  toothed 
  — 
  that 
  with 
  an 
  inflexed 
  keel, 
  

   with 
  a 
  broad, 
  obtuse 
  apex, 
  this 
  is 
  very 
  sharp, 
  and 
  can 
  only 
  be 
  said 
  to 
  be 
  erect. 
  

   L. 
  Torreijv$ 
  has 
  a 
  red 
  brown 
  pubescence, 
  and 
  dense, 
  long- 
  bracted 
  racemes 
  ; 
  

   should 
  it 
  even 
  eventually 
  prove 
  a 
  variety, 
  we 
  have 
  as 
  yet 
  no 
  adequate 
  descrip- 
  

   tion 
  of 
  that 
  species, 
  to 
  warrant 
  the 
  reference. 
  Found 
  near 
  Lake 
  Tahoe. 
  

  

  In 
  many 
  respects 
  it 
  is 
  closely 
  allied 
  to 
  L. 
  holocerkus, 
  found 
  on 
  the 
  islands 
  and 
  

   gravel 
  banks 
  of 
  the 
  Wahlamet, 
  by 
  Nutt. 
  ; 
  but 
  the 
  pods 
  of 
  that 
  have 
  3 
  or 
  4 
  

   seeds, 
  this, 
  1 
  to 
  2 
  ; 
  in 
  this, 
  the 
  lower 
  lip 
  we 
  have 
  never 
  found 
  " 
  entire," 
  but 
  with 
  

   2 
  rather 
  cleft 
  teeth 
  (and 
  rarely 
  3). 
  In 
  the 
  remarks 
  upon 
  this 
  species, 
  of 
  Nutt.- 
  

   it 
  is 
  stated 
  that 
  the 
  upper 
  leaflets 
  are 
  as 
  long 
  as 
  the 
  leaf 
  stem 
  (petiole).
