  Observations.

  (1.

  adds, 
  evidently 
  quoting

  The 
  pink 
  

   color 
  seen 
  in 
  tbe 
  herbaria 
  may 
  therefore 
  be 
  due 
  to 
  changes 
  in 
  

   drying, 
  as 
  some 
  other 
  spécimens 
  in 
  this 
  collection 
  had 
  undergone 
  

   the 
  same 
  change. 
  A 
  discussion 
  of 
  other 
  collections 
  will 
  be 
  given 
  

   elsewhere; 
  we 
  may
