  Botanists 
  everywhere 
  are 
  reporting 
  the 
  results 
  of 
  our 
  mild 
  winter 
  

   m 
  calling 
  forth 
  spring 
  flowers. 
  The 
  Washington 
  botanists 
  report 
  the 
  

   collecting 
  of 
  over 
  twenty 
  spring 
  flowers 
  in 
  January, 
  including 
  Epig^ea. 
  

  

  Ernest 
  Cosson 
  died 
  in 
  Paris, 
  December 
  31, 
  1889, 
  in 
  his 
  69th 
  year. 
  

   His 
  name 
  is 
  especially 
  connected 
  with 
  the 
  Algerian 
  flora, 
  although 
  in 
  his 
  

   earher 
  years 
  he 
  published 
  a 
  flora 
  of 
  the 
  suburbs 
  of 
  Paris, 
  which 
  has 
  gone 
  

   through 
  three 
  editions. 
  

  

  Mr. 
  Frank 
  Tweedy, 
  of 
  the 
  U. 
  S. 
  Geological 
  Survey, 
  is 
  always 
  finding 
  

   rare 
  and 
  new 
  plants 
  in 
  connection 
  with 
  his 
  regular 
  work. 
  He 
  has 
  done 
  

   much 
  in 
  bringing 
  to 
  light 
  the 
  rarities 
  of 
  the 
  Montana 
  flora. 
  Some 
  of 
  

   his 
  recent 
  discoveries 
  will 
  soon 
  fce 
  publi&hed. 
  

  

  The 
  amount 
  of 
  material 
  being 
  collected 
  at 
  the 
  Department 
  of 
  Ag- 
  

   riculture 
  for 
  the 
  study 
  of 
  North 
  American 
  grasses 
  is 
  really 
  enormous. 
  It 
  

   IS 
  to 
  be 
  hoped 
  that 
  both 
  time 
  and 
  strength 
  will 
  be 
  given 
  to 
  Dr. 
  Vasey 
  to 
  

   publish 
  fully 
  the 
  results 
  of 
  his 
  many 
  years 
  of 
  study. 
  

  

  In 
  Forest 
  Leaves 
  (Jan,) 
  Dr. 
  Rothrock 
  writes 
  of 
  a 
  puzzling 
  walnut 
  tree 
  

   growing 
  on 
  the 
  Eow 
  Farm, 
  on 
  the 
  northern 
  bank 
  of 
  the 
  James 
  River 
  ''a 
  

   good 
  day's 
  sail 
  above 
  Newport 
  News." 
  It 
  is 
  a 
  gigantic 
  tree, 
  and 
  has 
  been 
  

   called 
  J, 
  cinerea, 
  J. 
  nigra, 
  J. 
  regia, 
  and 
  a 
  hybrid 
  between 
  the 
  last 
  two. 
  

   Professor 
  Eothrock 
  seems 
  not 
  to 
  have 
  settled 
  the 
  puzzle. 
  

  

  The 
  discovery 
  of 
  Liriodendron 
  Tulipifera 
  in 
  Western 
  China 
  by 
  Dr. 
  

   Henry 
  is 
  a 
  striking 
  confirmation 
  of 
  Dr. 
  Gray's 
  essay 
  concerning 
  the 
  close 
  

   relationship 
  between 
  the 
  floras 
  of 
  Eastern 
  North 
  America 
  and 
  Eastern 
  

   Asia. 
  This 
  Chinese 
  tulip 
  tree 
  seems 
  in 
  no 
  way 
  different 
  from 
  its 
  Ameri- 
  

   can 
  representative, 
  although 
  reports 
  so 
  far 
  do 
  not 
  give 
  it 
  such 
  height.

  The 
  Bulletin 
  of 
  the 
  Torrey 
  Botanical 
  Club 
  for 
  January 
  contains 
  much 
  

   interesting 
  matter. 
  F. 
  V. 
  Coville 
  publishes, 
  with 
  plate, 
  a 
  revision 
  of 
  the 
  

   U. 
  S. 
  species 
  of 
  Fuirena, 
  of 
  which 
  there 
  are 
  three, 
  with 
  a 
  new 
  variety 
  for 
  

   P. 
  ^quarrosa. 
  E. 
  L. 
  Greene, 
  in 
  his 
  bibliographical 
  notes, 
  replaces 
  Ehus 
  

   arcmatica 
  Ait., 
  by 
  the 
  older 
  R. 
  Canadensis 
  Marshall, 
  and 
  describes 
  a 
  new 
  

   variety 
  of 
  it 
  from 
  N. 
  Arizona; 
  he 
  also 
  replaces 
  Ruhus 
  Nutkanus 
  Moc. 
  by 
  

   R. 
  pcirviflorus 
  Nutt, 
  apparently 
  a 
  very 
  inappropriate 
  name. 
  N. 
  L. 
  Britton 
  

   describes 
  a 
  new 
  Rhexia 
  from 
  Egg 
  Harbor 
  City, 
  New 
  Jersey, 
  Thos. 
  C. 
  

   Porter 
  describes 
  new 
  varieties 
  of 
  Arabis 
  laevigata, 
  Fragaria

  Ruhus 
  

   villosus, 
  and

  The 
  sudden 
  death 
  on 
  Tuesday, 
  December 
  3d, 
  of 
  W. 
  R. 
  McNab 
  is 
  

   announced. 
  Dr. 
  McNab, 
  the 
  son 
  and 
  grandson 
  of 
  the 
  distinguished 
  

   curators 
  of 
  the 
  Royal 
  Botanic 
  Garden 
  at 
  Edinburgh, 
  was 
  at 
  the 
  time

   his 
  death 
  Professor 
  of 
  Botany 
  at 
  the 
  Roj-al 
  College 
  of 
  Science, 
  Dublin, 
  

   and 
  the 
  director 
  at 
  the 
  Botanic 
  Garden 
  at 
  Glasnevin. 
  He 
  was 
  dis- 
  

   tinguished 
  by 
  his 
  investigations 
  in 
  physiological 
  botany 
  amd 
  the 
  minute 
  

   anatomy 
  of 
  plants, 
  both 
  recent 
  and 
  fossil 
  Dr. 
  McNab 
  is, 
  perhaps, 
  best 
  

   known 
  by 
  his 
  researches 
  into 
  the 
  minute 
  anatomy 
  of 
  the 
  leaves 
  of 
  

   conifers. 
  He 
  has 
  for 
  many 
  years 
  been 
  an 
  active 
  and 
  successful 
  teacher.
