Culm ancipital, naked ; umbel decompounded ; spikelets ovate. 



Leaves radical, grassy, loose, somewhat ragged, often the length of the culms, 

 vrh are a hand high, compressed, keeled a little on one side. Involucre terminating, 

 tu >. k ivecl, like t e leaver, comjiionly longer than the umbel ; which is spreading and 

 un qua). The ; ve generally three spikes. Scales ovate, ferruginous^

Culm three-sided, almost naked ; involucres length of the panicle and cilia; e. 



" This species varies remarkably from a span to two feet in height ; and is easily dis-
