varieties of C. ovccps. In different states and situations the 

 leaves of this species are found from an inch and a half to a 

 line in width ; and the form of the fruit and scales is also quite 

 variable: we are, however, unabb to dislingaish anyone of 

 the narrow-leaved va.i^t'es as a distinct species.

Hab. Canada! to Louisiana! — This species, like C. 

 anceps, sometimes occurs with broad leaves ; and in this va- 

 riety (C oligocarpo. var. lafifulia, Gray, Gram. ^ Cyp. part 2. 

 no. 178) the leaves are usually glaucous, the spikes more 

 densely flowered, and the fruit usually somewhat larger. The 

 figure of Schkuhr represents the plant with fewer flowers than 

 is usual, but is obviously intended to represent this species.
