  Some 
  of 
  tliese 
  specimens 
  are 
  very 
  yonng 
  and 
  may 
  be 
  

   taken 
  for 
  the 
  nearly 
  allied 
  Carex 
  pnrimreo-raginata 
  Boeck., 
  

   which 
  differs 
  by 
  narrower, 
  more 
  distinctly 
  ribbed 
  utricle. 
  

   In 
  the 
  Carex 
  Sonderiana 
  Boott 
  (\Vidgren's 
  specimen, 
  com- 
  

   pared 
  by 
  Mr. 
  Clarke 
  with 
  the 
  original 
  spec. 
  in 
  Herb. 
  Boott) 
  

   the 
  utricle 
  is 
  broadly 
  lanceolate 
  (the 
  beak 
  not 
  regarded), 
  or 
  

   subovate, 
  3 
  mm 
  long, 
  1,5 
  mm 
  broad; 
  the 
  rostrum 
  about 
  1 
  

   mm 
  long.

  true 
  Carex 
  piirpureo-vaginata

  really 
  a 
  

   distinct

  be

  (IVl^inas

  but 
  I 
  doubt; 
  their 
  utricles 
  are 
  nar- 
  

   rowly 
  lanceolate. 
  — 
  In 
  all 
  our 
  specimens 
  the 
  niits 
  are 
  alike, 
  

   very 
  narrowly 
  elliptical 
  or 
  sublanceolate, 
  obtusely 
  trigone, 
  

   hooked 
  at 
  the 
  top 
  by 
  the 
  remaining 
  base 
  of 
  the 
  style, 
  smooth, 
  

   påle 
  brownish, 
  about 
  2,6 
  mm 
  long 
  and 
  hardly 
  1 
  mm 
  broad.
