  Specimens 
  in 
  Nrttional 
  Herbarium 
  are 
  labelled 
  from 
  Nevada, 
  1872, 
  

   but 
  Eothrock's 
  Report 
  says 
  Arizona, 
  and 
  Dr. 
  Rothrock 
  writes 
  me 
  that 
  he 
  

   thinks 
  it 
  is 
  most 
  likely 
  from 
  Nevada.

  Hinds 
  (1837) 
  and 
  Brandegee 
  (1889), 
  Bay 
  of 
  Magdalena, 
  Lower 
  Cali- 
  

   fornia. 
  The 
  history 
  of 
  this 
  species 
  is 
  curious 
  and. 
  interesting. 
  It 
  was 
  

   collected 
  first 
  in 
  1837 
  at 
  Magdalena 
  Bay 
  and 
  described 
  (with 
  piate) 
  in 
  

   the 
  Bot. 
  of 
  the 
  Sulphur, 
  by 
  Mr. 
  Bentham 
  in 
  1844. 
  Nothing 
  more 
  is 
  said 
  

   of 
  it 
  until 
  1862, 
  when 
  Dr. 
  Gray 
  in 
  Proc. 
  Amer. 
  Acad, 
  refers 
  Xantus's 
  

   specimen 
  from 
  Cape 
  St. 
  Lucas 
  to 
  it, 
  and 
  in 
  the 
  Botany 
  of 
  California 
  he 
  

   still 
  refers 
  to 
  those 
  two 
  specimens 
  as 
  representing 
  all 
  of 
  P. 
  Californica. 
  

   In 
  the 
  Synoptical 
  Flora, 
  however, 
  he 
  refers 
  Xantus's 
  specimen, 
  his 
  only 
  

   representative 
  of 
  P. 
  Californica* 
  to 
  P. 
  microglossa, 
  and 
  takes 
  up 
  P. 
  Emo- 
  

   ryi 
  for 
  that 
  species 
  (P. 
  CaUfornica). 
  And 
  now, 
  this 
  past 
  season, 
  Mr. 
  

   Brandegee 
  has 
  collected 
  at 
  the 
  original 
  station 
  the 
  true 
  form 
  of 
  Ben- 
  

   tham's 
  species, 
  which 
  will 
  require 
  the 
  referring 
  back 
  to 
  P. 
  Emoryi 
  the 
  P. 
  

   Californica 
  of 
  all 
  modern 
  authors. 
  There 
  is 
  still 
  one 
  point 
  which 
  is 
  a 
  

   little 
  confusing 
  : 
  Mr. 
  Brandegee's 
  specimens 
  are 
  slender 
  and 
  not 
  much 
  

   branched, 
  while 
  Bentham's 
  figure 
  resembles 
  some 
  forms 
  of 
  P. 
  Emoryi. 
  

   But 
  as 
  Mr. 
  Brandegee's 
  specimens 
  show 
  the 
  exactakenes 
  with 
  their 
  thick 
  

   callous 
  margin, 
  peculiar 
  crown, 
  and 
  awns, 
  and 
  the 
  yellow 
  rays 
  of 
  Ben- 
  

   tham's 
  description 
  and 
  figure, 
  it 
  seems 
  to 
  be 
  the 
  true 
  P. 
  Californica. 
  

   Should 
  the 
  habit 
  (a 
  most 
  valuable 
  thing 
  in 
  this 
  genus) 
  dominate, 
  it 
  

   would 
  require 
  a 
  new 
  name, 
  otherwise 
  the 
  old 
  and 
  familiar 
  name 
  is 
  

   taken 
  up,

  Watson. 
  Very 
  near 
  to 
  P. 
  Californica 
  in 
  

   habit 
  and 
  in 
  the 
  akenes, 
  but 
  the 
  latter 
  have 
  a 
  somewhat 
  dif- 
  

   ferent 
  crown 
  and 
  there 
  are 
  slight 
  differences 
  in

  corolla 
  

   and
