Entoplocamia

Annual, tufted, robust. Leaf blade linear-lanceolate, expanded or rolled, glaucous; ligule a fringe of short hairs. Inflorescence a spike, raceme, or contracted panicle, sometimes spike-like, often in glomerate racemes; spikelets solitary or clustered, sessile or subsessile. Spikelet rather large, spiny, laterally compressed, becoming twisted when mature, disarticulating with glumes (spikelets falling whole); glumes unequal to +/- equal, much shorter than spikelet, membranous, ovate, acuminate, hairy or glabrous, awnless; lower glume 3-nerved; upper glume 5-nerved. Florets few to many; lower 2 florets sterile and uppermost floret reduced, male or sterile; remaining florets bisexual, keeled, woolly at base near margins; sterile lemma 6-8-nerved; bisexual lemma firmer than glumes, 9-11-nerved in upper half, almost nerveless below, entire, hairy, mucronate to awned; awn straight, stout, deflexed, shorter than body of lemma; palea as long as lemma, shortly 2-lobed, 2-keeled, with keels winged and ciliate on back, woolly at base. Lodicules 0. Stamens 3. Ovary glabrous; styles connate at base, plumose above. Caryopsis ellipsoid. x= 10.
