  In 
  the 
  December 
  Gazette, 
  p. 
  318^ 
  reference 
  was 
  made 
  to 
  the 
  fact 
  that 
  

   Amos 
  Eaton 
  had 
  sent 
  three 
  specimens 
  of 
  roses 
  from 
  the 
  same 
  bush 
  to 
  

   Sir 
  Joseph 
  Smith, 
  who 
  determined 
  them 
  to 
  be 
  as 
  many 
  distinct 
  species. 
  

   The 
  specimens 
  were 
  sent 
  by 
  Dr. 
  Bigelow 
  and 
  the 
  story 
  narrated 
  by 
  Amos 
  

   Eaton 
  (see 
  Watson, 
  Proc. 
  Am. 
  Acad. 
  20. 
  328). 
  

  

  The 
  first 
  fascicle 
  of 
  economic 
  fungi, 
  issued 
  by 
  A. 
  B. 
  Seymour 
  and 
  

   F, 
  S. 
  Earle,i8 
  now 
  ready. 
  The 
  series 
  is 
  intended 
  to 
  supply 
  a 
  set 
  of 
  au- 
  

   thentic 
  specimens 
  to 
  illiastrate 
  the 
  diseases 
  of 
  useful 
  and 
  noxious 
  plants. 
  

   The 
  first 
  fascicle 
  contains 
  60 
  species, 
  and 
  is 
  a 
  general 
  collection 
  of 
  de- 
  

   structive 
  parasites, 
  especially 
  those 
  of 
  the 
  vine 
  and 
  rose 
  families. 
  The 
  

   price 
  is 
  $3.00 
  for 
  specimens 
  in 
  envelopes, 
  or 
  $3.50 
  for 
  a 
  copy 
  mounted 
  in 
  

   book 
  form. 
  

  

  The 
  last 
  annual 
  report 
  of 
  the 
  state 
  botanist 
  of 
  I^ew 
  York, 
  dated 
  De- 
  

   cember 
  10, 
  1888, 
  has 
  just 
  appeared. 
  Besides 
  the 
  usual 
  lists 
  of 
  additions 
  

   to 
  the 
  herbarium, 
  it 
  contains 
  descriptions 
  of 
  44 
  new 
  species 
  of 
  fungi, 
  

   with 
  a 
  synopsis 
  of 
  the 
  New 
  York 
  species 
  of 
  Clitopilus 
  (14 
  species), 
  and 
  

   two 
  plates. 
  Our 
  species 
  of 
  Clitopilus 
  seem 
  to 
  be 
  peculiarly 
  American, 
  but 
  

   2 
  of 
  the 
  14 
  occurring 
  in 
  Europe, 
  and 
  10 
  of 
  them 
  having 
  been 
  described 
  

   by 
  Mr. 
  Peck. 
  

  

  In 
  the 
  Journal 
  of 
  Botany 
  (Dec.) 
  is 
  the 
  second 
  report 
  of 
  the 
  commit- 
  

   tee 
  appointed 
  by 
  the 
  British 
  Association 
  to 
  report 
  upon 
  the 
  disappearance 
  

   of 
  British 
  plants. 
  The 
  alpine 
  plants 
  are 
  especially 
  the 
  sufferers, 
  and 
  

   many 
  of 
  them 
  are 
  entirely 
  extirpated 
  from 
  their 
  well-known 
  haunts. 
  

   The 
  blame 
  is 
  laid 
  chiefly 
  upon 
  dealers 
  and 
  collectors, 
  the 
  summer 
  visit- 
  

   ors 
  being 
  only 
  indirectly 
  responsible. 
  A 
  list 
  of 
  55 
  species 
  is 
  given, 
  which 
  

   are 
  either 
  extirpated 
  or 
  nearly 
  so. 
  

  

  In 
  the 
  Balletin 
  rf 
  the 
  Torrey 
  Bdanical 
  Club 
  for 
  December 
  Prof. 
  Jos. 
  

   Schrenk 
  has 
  a 
  paper 
  on 
  " 
  The 
  floating 
  tissue 
  of 
  Nessea 
  verticillata," 
  in 
  

   which 
  is 
  described, 
  with 
  the 
  aid 
  of 
  three 
  handsome 
  lithograph 
  plates, 
  the 
  

   same 
  tissue 
  which 
  Schenk 
  in 
  his 
  recent 
  monograph 
  (see 
  this 
  journal 
  

   xiv. 
  317) 
  calls 
  aerenchyma. 
  Professor 
  Schrenk 
  inclines 
  to 
  the 
  opinion 
  of 
  

   earlier 
  students 
  of 
  this 
  tissue 
  that 
  it 
  is 
  not 
  so 
  much 
  an 
  adaptation 
  for 
  

   aeration 
  as 
  for 
  floating 
  the 
  shoots. 
  

  

  In 
  a 
  paper 
  recently 
  (Nov.) 
  read 
  before 
  the 
  American 
  Academy 
  by 
  

   Dr. 
  Geo. 
  L. 
  Goodale, 
  the 
  author 
  gave 
  some 
  results 
  of 
  a 
  series 
  of 
  experi- 
  

   ments 
  on 
  the 
  effects 
  produced 
  on 
  some 
  tropical 
  plants 
  by 
  a 
  temperature 
  

   of 
  40 
  to 
  34 
  degrees. 
  Briefly 
  stated 
  they 
  are 
  as 
  follows: 
  (1) 
  no 
  physical 
  

   injury 
  apparent 
  to 
  the 
  cell-wall; 
  (2) 
  effect 
  on 
  protoplasmic 
  contents 
  

   merely 
  a 
  redviction 
  of 
  rate 
  of 
  circulation; 
  (3) 
  no 
  appreciable 
  change 
  in 
  

   the 
  size 
  of 
  sap-cavities; 
  (4) 
  a 
  notable 
  reduction 
  of 
  the 
  power 
  of 
  plasino- 
  

   lytic 
  agents, 
  plainly 
  pointing 
  to 
  a 
  diminution 
  in 
  the 
  power 
  of 
  absorption. 
  

  

  As 
  THERE 
  continues 
  to 
  be 
  a 
  call 
  for 
  the 
  key 
  to 
  the 
  genera 
  of 
  mosses 
  

   published 
  in 
  1886 
  by 
  one 
  of 
  the 
  editors 
  (B.), 
  the 
  announcement 
  is 
  made 
  

   that 
  the 
  edition 
  is 
  now 
  entirely 
  exhausted. 
  There 
  is 
  reason 
  to 
  think 
  that 
  

   this 
  key 
  has 
  been 
  helpful 
  to 
  a 
  considerable 
  number 
  of 
  the 
  less 
  experi- 
  

   enced 
  students 
  of 
  mosses 
  and 
  has 
  perhaps 
  encouraged 
  some 
  to 
  undertake 
  

   their 
  study. 
  The 
  author 
  has, 
  therefore, 
  with 
  the 
  hope 
  of 
  still 
  further 
  in- 
  

   creasing 
  the 
  number 
  of 
  amateurs, 
  undertaken 
  the 
  preparation 
  of 
  keys 
  to 
  

   the 
  species 
  of 
  the 
  larger 
  genera 
  of 
  mosses, 
  and 
  hopes 
  to 
  republish 
  the 
  key 
  

   to 
  genera 
  with 
  this 
  additional 
  matter 
  at 
  an 
  early 
  day. 
  He 
  would 
  be 
  thank- 
  

   ful, 
  therefore, 
  to 
  have 
  any 
  errors 
  or 
  omissions 
  in 
  the 
  key 
  to 
  genera 
  

   pointed 
  out.
