  with 
  the 
  generic 
  description, 
  as 
  it 
  now 
  stands, 
  it 
  is 
  manifest 
  that 
  a 
  slight 
  re- 
  

   vision 
  only 
  is 
  required 
  to 
  welcome 
  this 
  remarkable 
  discovery. 
  

  

  If, 
  from 
  generic 
  differences 
  above 
  indicated, 
  and 
  more 
  ample 
  means 
  of 
  investi- 
  

   gation, 
  this 
  should 
  be 
  deemed 
  of 
  intermediate 
  generic 
  position 
  between 
  Chion- 
  

   anthus 
  and 
  Fcrsyt/iia, 
  it 
  should 
  be 
  entitled 
  Ayrseia 
  fraxinifolia. 
  

  

  Dr. 
  Ayres 
  observes 
  : 
  " 
  When 
  young, 
  a 
  graceful 
  and 
  beautiful 
  tree 
  or 
  shrub, 
  

   as 
  it 
  grows 
  older, 
  it 
  loses 
  its 
  beauty 
  very 
  much 
  — 
  becomes 
  straggling 
  and 
  irreg- 
  

   ular, 
  never 
  showing 
  a 
  straight 
  symmetrical 
  trunk 
  ; 
  25 
  to 
  30 
  feet 
  high."
