  In 
  three 
  short 
  notes 
  by 
  Dr. 
  B.D. 
  

   Halsted, 
  attention 
  was 
  called 
  to 
  the 
  occurrence 
  of 
  double 
  

   flowers 
  in 
  wild 
  Convolvulus 
  sepium 
  ; 
  to 
  peculiarities 
  of 
  the 
  

   pollen 
  of 
  Epilobium 
  palustre 
  var. 
  oliganthum 
  ; 
  and 
  to 
  a 
  sup- 
  

   posed 
  hybrid

  Tragopogon 
  porrifohus

   tensis. 
  

  

  Miss 
  E. 
  Porter, 
  of 
  Cornell 
  University, 
  described 
  -a 
  mode 
  

   of 
  spore 
  discharge 
  in 
  a 
  species 
  of 
  Pleospora 
  in 
  which 
  the 
  

   spores 
  are 
  expelled 
  simultaneously 
  after 
  the 
  elongation 
  of 
  the 
  

   inner 
  coat 
  of 
  the 
  ascus 
  and 
  its 
  circumscissile 
  dehiscence. 
  

  

  H. 
  L. 
  Bolley, 
  of 
  Purdue 
  University, 
  explained 
  the 
  results 
  

   of 
  a 
  large 
  series 
  of 
  experiments 
  on 
  potato 
  scab 
  which 
  he 
  is 
  

   confident 
  is 
  a 
  bacterial 
  disease. 
  The 
  author 
  also 
  discussed 
  

   the 
  histology 
  and 
  biology 
  of 
  the 
  disease 
  fully 
  and 
  gave 
  an 
  

   outline 
  of 
  infection 
  and 
  culture 
  experiments. 
  The 
  work 
  was 
  

   very 
  highly 
  commended 
  by 
  Dr. 
  Burrill 
  who 
  had 
  given 
  atten- 
  

   tion 
  to 
  the 
  disease 
  himself. 
  Dr. 
  Arthur 
  pointed 
  out 
  the 
  cu- 
  

   rious 
  fact 
  that 
  in 
  order 
  to 
  succeed 
  with 
  infection 
  experiments 
  

   the 
  tubers 
  must 
  not 
  only 
  be 
  attached 
  to 
  the 
  plant 
  but 
  must 
  be 
  

   in 
  a 
  healthy 
  growing 
  condition.
