mistaken for C. cryptocarpa, small forms of wliich it very closely re- 

 sembles. It differs from that species in its shorter peduncles (the 

 upper two or three not over a half-inch long) and its nearly erect upper 

 spikes, its nerveless perigynium which is sprinkled with ferruginous 

 dots, and the much shorter scales (seldom over half as long again as 

 the perigynium).

Spikes shorter and narrower than in the species, often an inch or 

 less long, '' pale from the predominance of the perigynia over the 

 squamiB": perigynium greenish, strongly nerved, resembling that of 

 G. lenticularis. — Oregon, Lyall, Hall 593; Summit Camp, Calif., Dr. 

 Kellopg ; and probably also specimens distributed as O. lenticularis by 

 Olney from Maine, coll. by Blake or Porter. Little known ; probably 

 to be associated with some other species.
