This species is admirably figured in Scbk., and though — 
rather a rare plant, has very distinct characters. Culm 
12—18 inches high, ‘triangular, striate, scabrous above ; 
leaves sheathing linear-lanceolate, glabrous, scabrous on the 
edges, keeled, longer r than the culm, lower ones abbrevia- 
heath © ous, striate, terminating in a straight sti- 
ule opposite the leaf; spikes 5—7, rather clustered, stam- 
inate above, ened by an ovate bract ending in a sca- 
brous awn, longer than the spikelet; fruit ovate, compres- 
sed, somewhat concavo-convex, scabrous, or ciliate-serrate 
on the edge, bidentate, nervy ed, and somewhat diverging ; 
pistillate scale ovate, nearly the length of the fruit, and ter- 
Senee 2 in an awn extending a little beyond the fruit.

In the aggregation of the spikelets, this species often re- 
sembles C. ceph alophora, from which, ho wever, itis easily 
distinguished by its fruit, and scale.
