Description - Mostly large tussock grasses, the leaves generally crowded at the base, the blades long and narrow, tapering to a slender point, usually very rough on the margins ; spikelets several-flowered, the rachilla disarticulating near the base of the internodes, the lower shorter part glabrous, the upper longer part bearded, forming a stipe to the floret; rachilla and florets clothed with long hairs; glumes longer than the first floret (excluding awn), sometimes longer than all the florets ; lemma tapering into a slender point or awn, or awned from between the slender teeth of a bifid apex; inflorescence a panicle, sometimes large and plumelike.—In all the species except C. scricantha the old sheaths become flattened and coiled at the base of the plant. The genus has been described as dioecious, but some of the species have perfect florets, though the anthers are small and the flowers appear to be cleistogamous.
