  adoption 
  of 
  this 
  system 
  would 
  have 
  considerably 
  increased 
  the 
  number 
  of 
  

   changed 
  names 
  in 
  the 
  new 
  Manual. 
  Although 
  the 
  tendency 
  referred 
  to 
  

   repudiates 
  in 
  several 
  important 
  respects 
  the 
  code 
  adopted 
  by 
  the 
  Con- 
  

   gress 
  of 
  1867, 
  which 
  was 
  framed 
  by 
  botanists 
  quite 
  as 
  wise 
  in 
  their 
  day 
  

   and 
  generation 
  as 
  any 
  who 
  now 
  pass 
  judgment 
  on 
  their 
  views, 
  it 
  can 
  not 
  

   be 
  denied 
  that 
  a 
  rigid 
  application 
  of 
  the 
  principle 
  of 
  priority 
  can 
  scarcely 
  

   lead 
  to 
  any 
  other 
  result; 
  and 
  it 
  may 
  be 
  that 
  with 
  the 
  concurrence 
  of 
  the 
  

   next 
  generation 
  the 
  temporary 
  unstability 
  of 
  the 
  nomenclature 
  will 
  

   finally 
  give 
  the 
  real 
  stability 
  that 
  all 
  botanists 
  desire. 
  At 
  any 
  rate, 
  there 
  

   is 
  yet 
  room 
  for 
  an 
  honest 
  difference 
  of 
  opinion 
  on 
  some 
  points 
  involved, 
  

   and 
  although 
  this 
  may 
  make 
  it 
  the 
  duty 
  of 
  monographers 
  to 
  indicate 
  as 
  a 
  

   synonym 
  the 
  name 
  that 
  a 
  given 
  plant 
  would 
  bear 
  under 
  the 
  system 
  that 
  

   they 
  reject, 
  this 
  could 
  hardly 
  have 
  been 
  expected 
  iu 
  a 
  work 
  like 
  the 
  

   Manual, 
  which 
  does 
  not 
  pretend 
  to 
  go 
  into 
  synonymy, 
  and 
  the 
  editors 
  of 
  

   the 
  new 
  edition 
  would 
  have 
  been 
  more 
  justly 
  criticised 
  had 
  they 
  followed 
  

   the 
  method 
  that 
  did 
  not 
  meet 
  with 
  the 
  approval 
  of 
  the 
  author 
  of 
  the 
  book* 
  

   than 
  they 
  can 
  be 
  for 
  doing 
  what 
  they 
  had 
  his 
  testimony 
  that 
  he 
  would 
  

   have 
  done 
  had 
  the 
  work 
  been 
  performed 
  by 
  his 
  own 
  hand. 
  In 
  this 
  connec- 
  

   tion, 
  however, 
  attention 
  ought 
  to 
  be 
  called 
  to 
  the 
  unadopted 
  changes 
  in 
  

   generic 
  names 
  in 
  the 
  ISTymphseaceas 
  that 
  have 
  recently 
  been 
  discussed 
  in 
  

   the 
  Bulletin 
  of 
  the 
  Torrey 
  Club, 
  and 
  to 
  the 
  unaccepted 
  substitution 
  of 
  

   Hicoria 
  for 
  the 
  familiar 
  Carya. 
  However 
  it 
  may 
  be 
  with 
  these 
  genera, 
  it 
  

   is 
  to 
  be 
  regretted 
  that 
  Spergularia 
  of 
  the 
  old 
  edition 
  appears 
  in 
  this 
  edi- 
  

   tion 
  as 
  Buda 
  and 
  not 
  Ti^sa. 
  The 
  priority 
  of 
  the 
  latter, 
  to 
  be 
  sure, 
  is 
  only 
  

   that 
  of 
  a 
  few 
  pages 
  of 
  a 
  book, 
  both 
  being 
  used 
  in 
  the 
  same 
  work 
  by 
  one 
  

   author; 
  but 
  the 
  birthright 
  of 
  Tissa 
  is 
  not 
  invalidated 
  by 
  this 
  fact, 
  and 
  its 
  

   use 
  in 
  a 
  recent 
  monograph 
  of 
  the 
  genus 
  by 
  Dr. 
  Britton, 
  prior 
  to 
  the 
  ap- 
  

   pearance 
  of 
  the 
  Manual, 
  is 
  an 
  additional 
  reason 
  for 
  its 
  use 
  there 
  as 
  a 
  

   means 
  of 
  avoiding 
  an 
  increase 
  in 
  the 
  number 
  of 
  synonyms. 
  

  

  The 
  usefulness 
  of 
  the 
  book, 
  for 
  beginners, 
  is 
  considerably 
  increased 
  

   by 
  the 
  incorporation 
  of 
  a 
  glossary, 
  not 
  found 
  in 
  the 
  last 
  edition, 
  and 
  by 
  

   the 
  provision 
  of 
  a 
  synopsis 
  of 
  the 
  orders 
  in 
  addition 
  to 
  the 
  well 
  arranged 
  

   artificial 
  keys; 
  and 
  the 
  index 
  now 
  includes 
  the 
  species 
  of 
  large 
  genera, 
  

  

  and 
  several 
  confusing 
  popular 
  names— 
  changes 
  that 
  greatly 
  facilitate 
  ref- 
  

   erence. 
  

  

  Those 
  who 
  use 
  the 
  book 
  during 
  the 
  coming 
  season, 
  especially 
  near 
  

   the 
  hmits 
  of 
  its 
  range, 
  are 
  likely 
  to 
  discover 
  little 
  shortcomings 
  in 
  the 
  

   distribution 
  of 
  species 
  : 
  and 
  to 
  such 
  it 
  should 
  be 
  a 
  pleasure 
  to 
  communi- 
  

   cate 
  to 
  the 
  editors 
  specimens 
  showing 
  any 
  considerable 
  omission. 
  

  

  Probably 
  those 
  who 
  study 
  local 
  floras, 
  where 
  it 
  is 
  frequently 
  easy 
  to 
  

   distinguish 
  varieties 
  without 
  transition 
  forms, 
  will 
  take 
  exception 
  to 
  the 
  

   Manual 
  blending 
  of 
  some 
  nominal 
  species 
  or 
  varieties 
  with 
  accepted 
  spe- 
  

   cies. 
  For 
  instance, 
  Poa 
  cristata 
  is 
  almost 
  too 
  distinct 
  from 
  annua 
  to 
  pass 
  

   for 
  a 
  mere 
  form 
  of 
  that 
  species, 
  and 
  Festuca 
  Shortii 
  is 
  equally 
  distinct 
  

   from 
  F, 
  nutans 
  in 
  its 
  typical 
  form; 
  and 
  it 
  is 
  probable 
  that 
  more 
  cases 
  of
