Of this, the leaves are slender, entirely radical, almost smooth, even at the margins, as is the slender, 

 rounded, or obtusely angular stem. The male spike is terminal, on a long peduncle, which arises from the 

 same sheath as the female spike. Each is constantly solitary. Braeteoe of the female spike reddish-brown, 

 with a broad pale-green nerve ; those of the male all red-brown.

Two other Carices exist in the Collection, but their fructification is not sufficiently advanced to enable us 

 to determine them.

This exactly agrees with the B. purgans of Dr. Richardson, which, however, has the leaves hairy, as 

 well as the florets and sheaths. In regard to the degree of hairiness, this species is probably liable to much 

 variation; and the B. pubescens of Muhl., the B. Canadensis of Mich., and the B. ciliatus of Linn., may 

 perhaps be only different states of one and the same species.

This is without fruit; but is remarkable for the narrow spinuloso-dentate contorted leaves, with a very 

 broad sheathing base.
