ENTEROPOGON Nees.
Plants hermaphroditic, caespitose or rhizomatous, perennial. Rhizomatous bearing cleistogamous spikelets subterranean in E. chlorideus. Culms erect to ascending, glabrous; internodes solid or hollow, terete. Leaves basal or basal and cauline, not distinctly distichous; sheaths terete, margins open; auricles absent; ligules a ciliate membrane; blades flat or involute, linear, lax, apex acuminate. Panicles (rarely a spike) with 2 to several spicate primary unilateral branches; branches paired or digitate or subdigitae or verticillate, ascending, terminating in a spikelet, spikelets in two rows. Spikelets solitary, dorsiventrally compressed, disarticulation above the glumes, awned, sessile or subsessile; florets 2-6, lowermost 1-2 perfect, reduced floret at apex (uppermost 1-4 sterile), callus hairy, rachilla not extended beyond upper floret, awned; glumes 2, 1-veined, unequal, the second longer than first floret, glabrous, awned (second glume); lemmas 3-veined, coriaceous or indurate, glabrous, apex entire or bifid, awn (1) from apex or between the bifid lobes; paleas 2-veined, glabrous, awnless. Stamens 3; anthers cream. Caryopses dorsiventrally compressed, elliptical to linear, brown, (caryopses of cleistogamous spikelet ovate). Base chromosome number x=10.

A genus of about six species that is often confused with Chloris. These shade species or open habitat species are adapted to medium to dry areas.
