﻿PREFACE 
  

  

  This 
  flora 
  is 
  a 
  considerably 
  enlarged 
  revision 
  of 
  the 
  one 
  pre- 
  

   pared 
  by 
  the 
  author 
  in 
  1901. 
  It 
  does 
  not 
  profess 
  to 
  describe 
  

   all 
  the 
  conspicuous 
  seed 
  plants 
  of 
  any 
  locality, 
  but 
  rather 
  to 
  

   comprise 
  a 
  large 
  number 
  of 
  the 
  most 
  available 
  spring-bloom- 
  

   ing 
  species 
  over 
  an 
  extensive 
  region. 
  More 
  than 
  a 
  hundred 
  

   species 
  have 
  been 
  added 
  to 
  the 
  list 
  included 
  in 
  the 
  older 
  

   edition, 
  mainly 
  of 
  plants 
  which 
  range 
  westward 
  to 
  the 
  moder- 
  

   ately 
  high 
  plains. 
  The 
  little 
  book 
  may 
  therefore 
  afford 
  a 
  

   good 
  deal 
  of 
  practice 
  in 
  the 
  determination 
  of 
  species 
  to 
  sec- 
  

   ondary-school 
  pupils 
  in 
  states 
  even 
  as 
  far 
  west 
  as 
  the 
  Dakotas, 
  

   Nebraska, 
  Kansas, 
  and 
  Oklahoma. 
  It 
  extends 
  south 
  about 
  to 
  

   the 
  southern 
  boundary, 
  of 
  Kansas 
  on 
  the 
  west 
  and 
  to 
  that 
  of 
  

   Virginia 
  on 
  the 
  east. 
  

  

  In 
  the 
  matter 
  of 
  nomenclature 
  it 
  seems 
  best 
  for 
  those 
  who 
  

   do 
  not 
  wish 
  to 
  be 
  hopelessly 
  sectional 
  to 
  follow 
  the 
  rulings 
  of 
  

   the 
  Vienna 
  Congress. 
  The 
  author 
  deems 
  himself 
  fortunate 
  to 
  

   have 
  been 
  able 
  in 
  this 
  connection 
  to 
  avail 
  himself 
  of 
  the 
  deci- 
  

   sions 
  of 
  the 
  staff 
  of 
  the 
  Gray 
  Herbarium, 
  as 
  embodied 
  in 
  the 
  

   seventh 
  edition 
  of 
  Gray's 
  Manual 
  of 
  Botany, 
  and 
  to 
  get 
  advice 
  

   from 
  the 
  same 
  source 
  in 
  regard 
  to 
  names 
  of 
  cultivated 
  plants 
  

   not 
  described 
  in 
  the 
  Manual. 
  His 
  most 
  sincere 
  thanks 
  are 
  

   hereby 
  tendered 
  for 
  this 
  invaluable 
  assistance. 
  

  

  At 
  the 
  risk 
  of 
  sometimes 
  seeming 
  pedantic 
  the 
  writer 
  has 
  

   adopted 
  the 
  practice 
  of 
  discarding, 
  for 
  the 
  most 
  part, 
  such 
  un- 
  

   scientific 
  expressions 
  as 
  " 
  stemless 
  plants," 
  " 
  radical 
  leaves," 
  

   " 
  calyx 
  adnate 
  to 
  the 
  ovary," 
  and 
  several 
  others. 
  It 
  is 
  certain 
  

   that 
  if 
  the 
  plant 
  descriptions 
  which 
  contain 
  such 
  terms 
  were 
  

   now 
  being 
  framed 
  for 
  the 
  first 
  time 
  on 
  the 
  basis 
  of 
  present- 
  

   day 
  morphology, 
  these 
  terms 
  would 
  not 
  be 
  used. 
  

  

  Most 
  of 
  the 
  plants 
  here 
  described 
  bloom 
  before 
  the 
  end 
  of 
  

   the 
  school 
  year, 
  and 
  it 
  is 
  believed 
  that 
  all 
  of 
  those 
  which 
  occur 
  

   toward 
  the 
  southern 
  limits 
  of 
  the 
  territory 
  covered 
  will 
  be 
  

   found 
  to 
  flower 
  there 
  considerably 
  before 
  the 
  end 
  of 
  June.
