  39-45

  In 
  these 
  numbers 
  the 
  authors 
  

   describe 
  13 
  new 
  species 
  and 
  14 
  new 
  varieties. 
  We 
  are 
  not 
  qualified 
  to 
  

   criticise 
  all 
  these 
  additions, 
  not 
  hiving 
  been 
  favored 
  with 
  specimens 
  : 
  but 
  

   of

  we 
  have 
  a 
  piece 
  of 
  the 
  type 
  from 
  M. 
  Cardot 
  and 
  

  

  abundant 
  specimens 
  from 
  A. 
  B.

  we 
  find 
  a 
  distinct 
  inverted

  DiDYMoDOK 
  Hendersoxi 
  was 
  evidently 
  described 
  from 
  old 
  imperfect 
  

   specimens, 
  like 
  ours 
  collected 
  March 
  14, 
  ISSo, 
  by 
  L. 
  F. 
  Henderson. 
  

   These 
  show 
  the 
  3'oung 
  pedicels 
  with 
  a 
  few 
  immature 
  capsules 
  and 
  the 
  old 
  

   fruit 
  of 
  the 
  previous 
  season. 
  In 
  the 
  former 
  the 
  pedicels 
  are 
  " 
  paler," 
  but 
  

   in 
  the 
  old 
  ones 
  they 
  are 
  quite 
  as 
  dark 
  as 
  in 
  D. 
  Inridus. 
  

  

  The 
  average 
  size 
  

  

  of 
  the 
  capsules 
  is 
  in 
  excess 
  of 
  ours, 
  which 
  measure 
  one 
  to 
  two 
  mm. 
  in 
  

   length. 
  The 
  drawings 
  seem 
  to 
  have 
  been 
  made 
  from 
  the 
  young 
  green 
  

   leaves 
  at 
  the 
  tips 
  of 
  the 
  fresh 
  branches, 
  whereas 
  the 
  older 
  brown 
  ones 
  on 
  

   the 
  stems 
  of 
  the 
  previous 
  year 
  do 
  not 
  show 
  such 
  triangular, 
  blunt 
  

   apexes 
  and 
  have 
  a 
  prominent 
  dark 
  brown 
  percurrent 
  costa 
  not 
  ceasing 
  

   below 
  the 
  apex 
  as 
  figured. 
  

  

  CosciNODON

  M. 
  Cardot 
  fails 
  to 
  state 
  that 
  I 
  sent 
  him 
  at 
  his 
  

   own 
  request 
  from 
  the 
  Austin 
  herbarium 
  Mrs. 
  Eoy's 
  Colorado 
  specimens' 
  

   telling 
  him 
  that 
  they 
  are 
  labeled 
  Grimmia 
  Eaui 
  in 
  Austin's 
  own 
  hand* 
  

   i 
  have 
  since 
  seen 
  specimens 
  from 
  E. 
  A. 
  Eau 
  which 
  agree 
  with 
  those 
  in 
  

   Austin's 
  collection; 
  "

  - 
  - 
  - 
  -

  -

  Grimmia

  they 
  are 
  labeled

  Colorado 
  specimens 
  

  

  They 
  are 
  the 
  ones 
  drawn 
  by 
  E. 
  A 
  Eau 
  at 
  the 
  time 
  the 
  

   description 
  was 
  published. 
  The 
  original 
  drawings, 
  in 
  our 
  herbarium, 
  are 
  

   marked 
  "leaves 
  throughout 
  chlorophyllose, 
  except 
  theexcurrent 
  costa

  The

  are 
  drawn

  entire 
  or 
  slightly

  What 
  Austin 
  probably 
  meant 
  when 
  he 
  said 
  

   costa

  sub 
  apice

  " 
  [Bull. 
  Torr. 
  Bot. 
  Club, 
  vi. 
  46] 
  was, 
  that 
  the 
  

   green 
  portion 
  of 
  the 
  costa 
  and 
  the 
  leaf

  before 
  reaching 
  the 
  apex

  hyaline

  decurrent 
  and 
  above 
  the 
  green, 
  careful 
  focusing 
  

   IS 
  required 
  to 
  see 
  the 
  costa, 
  whereas, 
  below, 
  it 
  is 
  very 
  heavy. 
  The 
  types 
  

   Show 
  all 
  stages 
  of 
  perforation 
  of 
  the 
  teeth, 
  from 
  those 
  nearly 
  entire 
  to 
  

   hers 
  which 
  are 
  divided 
  into 
  three 
  slender, 
  entirely 
  separate 
  portions. 
  

  

  I 
  am 
  quite 
  in 
  sympathy 
  with 
  the 
  editorial 
  in 
  the 
  March 
  number, 
  

  

  and 
  think 
  « 
  the 
  righteous, 
  conservative 
  systematist 
  " 
  will 
  have 
  to 
  do 
  some

  and 
  "weeding 
  out 
  ' 
  in 
  'the 
  future. 
  We 
  doubt 
  not 
  that 
  

  

  merican 
  bryology 
  will 
  profit 
  by 
  rigid 
  comparison 
  with 
  European 
  species, 
  

  

  at 
  our 
  collectors 
  are 
  at 
  fault 
  in 
  contributing
