﻿INDEX 
  TO 
  AMERICAN 
  BOTANICAL 
  LITERATURE 
  

  

  1917-1920 
  

  

  The 
  aim 
  of 
  this 
  Index 
  is 
  to 
  include 
  all 
  current 
  botanical 
  literature 
  written 
  by 
  

   Americans, 
  published 
  in 
  America, 
  or 
  based 
  upon 
  American 
  material 
  ; 
  the 
  word 
  Amer- 
  

   ica 
  being 
  used 
  in 
  the 
  broadest 
  sense. 
  

  

  Reviews, 
  and 
  papers 
  that 
  relate 
  exclusively 
  to 
  forestry, 
  agriculture, 
  horticulture, 
  

   manufactured 
  products 
  of 
  vegetable 
  origin, 
  or 
  laboratory 
  methods 
  are 
  not 
  included, 
  and 
  

   no 
  attempt 
  is 
  made 
  to 
  index 
  the 
  literature 
  of 
  bacteriology. 
  An 
  occasional 
  exception 
  is 
  

   made 
  in 
  favor 
  of 
  some 
  paper 
  appearing 
  in 
  an 
  American 
  periodical 
  which 
  is 
  devoted 
  

   wholly 
  to 
  botany. 
  Reprints 
  are 
  not 
  mentioned 
  unless 
  they 
  differ 
  from 
  the 
  original 
  in 
  

   some 
  important 
  particular. 
  If 
  users 
  of 
  the 
  Index 
  will 
  call 
  the 
  attention 
  of 
  the 
  editor 
  

   to 
  errors 
  or 
  omissions, 
  their 
  kindness 
  will 
  be 
  appreciated.
