 narrow, 1 to 3 inches long : sheaths purplish, leafless, usually tipped by a short 

 setaceous bract: terminal spike pistillate above: spikes all ovate ( inch or 

 less long), dull brown, hanging on slender peduncles from a half -inch to an 

 inch long : perigynium lanceolate, rough or serrate on the two margins, the 

 lower half occupied by the nearly flat 3-ribbed obovate akene, longer than the

 Peak, Colorado (H. N, Patterson, 1885); also in Arctic America. (Eu.) 

 C. misandra is the more recent name, but Sternberg and Hoppe applied the 

 name C. fuliginosa to this species, thinking it to be the (7. fuliginosa of 

 Schkuhr, which is C. frigida, All. The species was first distinguished by 

 Robert Brown.
