  His

  must 
  be 
  remarkably 
  rich 
  in 
  western 
  plants, 
  

   and 
  is 
  deposited,

  we

  In 
  Dr. 
  Parry's 
  death 
  we 
  lose 
  another 
  of 
  our 
  veteran 
  bot- 
  

   anists, 
  and 
  the 
  day 
  seems 
  not 
  far 
  distant 
  when 
  an 
  entirely 
  

   new 
  generation 
  will 
  stand 
  for 
  American 
  botany.

  and

  the

  and

  has 
  been 
  adopted 
  by

  Durand'a 
  Index* 
  has 
  been 
  taken 
  as 
  the 
  basis 
  for 
  nomenclature 
  and 
  

   arrangement. 
  This 
  book 
  forms 
  a 
  compact 
  index 
  of 
  the 
  genera 
  and 
  or- 
  

   ders 
  of 
  Phanerogams, 
  based 
  upon 
  the 
  Genera 
  Plautarum 
  of 
  Bentham 
  and 
  

   Hooker, 
  and 
  pubUshed 
  with 
  Hooker's 
  approval. 
  The 
  Genera 
  Plantar 
  um 
  

   was 
  published 
  in 
  parts, 
  covering 
  a 
  period 
  of 
  twenty-one 
  years, 
  ending 
  in 
  

   1883. 
  The 
  changes 
  in 
  nomenclature 
  during 
  this 
  period, 
  notably 
  those 
  

   brought 
  out 
  m 
  DeCandolIe's 
  Monographs, 
  have 
  been 
  incorporated 
  in 
  

   the 
  work. 
  It 
  will 
  be, 
  for 
  many 
  years 
  to 
  come, 
  the 
  standard 
  index 
  to 
  the 
  

   genera 
  of 
  Phanerogams, 
  and 
  the 
  general 
  use 
  of 
  its 
  numbers 
  bv 
  botanists 
  

   will 
  greatly 
  aid 
  reference 
  to 
  and 
  between 
  large 
  herbaria. 
  Our 
  standard 
  

   check-hsts, 
  too, 
  should 
  use 
  the 
  same 
  numbers 
  for 
  orders 
  and 
  genera. 
  

  

  The 
  general 
  plan 
  and 
  arrangement 
  of 
  the 
  genera 
  and 
  orders 
  in 
  the 
  

   the 
  work 
  IS 
  that 
  of 
  the 
  Genera 
  Plantarum, 
  the 
  Gymnosperms, 
  however, 
  

   being 
  placed 
  last. 
  The 
  orders 
  are 
  consecutively 
  nutubered, 
  and 
  the 
  

   genera 
  arranged 
  in 
  each 
  systematically 
  and 
  numbered, 
  beginning 
  in 
  

   each 
  order 
  with 
  1. 
  In 
  addition, 
  the 
  genera 
  are 
  provided 
  with 
  another 
  set 
  

   of 
  numbers 
  begmning 
  with 
  tbe 
  first 
  in 
  Kanunculacea. 
  and 
  running 
  on 
  

   consecutively 
  to 
  the 
  last 
  in 
  Cycadace*. 
  This 
  gives 
  to 
  each 
  genus 
  a 
  

   ready 
  reference 
  number,
