  Introduction 
  

  

  The 
  Californian 
  annuals 
  of 
  the 
  subgenus 
  Lupinus 
  have 
  long 
  

   been 
  recognized 
  as 
  separating 
  into 
  two 
  divisions, 
  the 
  verticillate- 
  

   flowered 
  forms 
  and 
  those 
  with 
  flowers 
  not 
  in 
  verticils. 
  As 
  already 
  

   shown 
  by 
  me 
  (Bull. 
  Torrey 
  Club 
  46: 
  390), 
  this 
  classification 
  holds 
  

   good 
  in 
  the 
  subgenus 
  Platycarpos, 
  if 
  one 
  exception 
  is 
  provided 
  for. 
  

   It 
  likewise 
  may 
  be 
  applied 
  to 
  the 
  annuals 
  and 
  biennials 
  of 
  North 
  

   America 
  in 
  general, 
  north 
  of 
  Panama, 
  but 
  breaks 
  down 
  in 
  the 
  

   Micranthi, 
  a 
  large 
  assemblage 
  of 
  variations 
  usually 
  with 
  real 
  

   verticils. 
  Serious 
  study 
  of 
  the 
  material 
  examined 
  prompts 
  

   recognition 
  of 
  at 
  least 
  five 
  groups, 
  only 
  one 
  of 
  which 
  will 
  be 
  

   treated 
  in 
  this 
  paper. 
  These 
  groups 
  will 
  include 
  the 
  so-called 
  

   biennials 
  of 
  Texas 
  and 
  adjacent 
  Mexico, 
  My 
  classification 
  

   contrasting 
  these 
  groups 
  will 
  be 
  presented 
  in 
  a 
  subsequent 
  paper.
