  Oarex

  Dewey. 
  

  

  A 
  form 
  with 
  the 
  leaves 
  more 
  narrow 
  than 
  usual 
  was 
  collected 
  

   on 
  the 
  boggy 
  shore

  Highland 
  lake. 
  

  

  Carex

   In 
  the 
  Manual, 
  this 
  sedge 
  is 
  subjoined 
  to 
  C. 
  rosea 
  as 
  a 
  variety. 
  

   It 
  differ^ 
  considerably 
  from 
  that 
  species 
  in 
  its 
  ranoje 
  as 
  well 
  as 
  in 
  

   its 
  appearance 
  and 
  characters. 
  I 
  do 
  not 
  find 
  it 
  at 
  all 
  in 
  the 
  

   northern 
  and 
  northeastern 
  counties 
  of 
  tne 
  State, 
  but 
  it 
  is 
  not 
  

   rare 
  in 
  some 
  of 
  the 
  southern 
  and 
  western 
  counties. 
  0. 
  rosea 
  is 
  

   common 
  everywhere 
  except 
  perhaps 
  in 
  the 
  coldest 
  mountain 
  

   regions.

   much 
  surpassing
