Leaves with sheath smooth, striate, loose; ligule a ciliate, membranous rim; blade flat or folded, margins scabrous.

Inflorescence a digitate arrangement of 3–6 spikes with spikelets in 2 close rows on 1 side of the spike axis.

Spikelets laterally compressed, sessile, solitary, rachilla disarticulating above the glumes; 1 bisexual floret with the rachilla continued as a sterile bristle. Glumes subequal, membranous, 1-nerved, rough along the back of the nerve. Lemma keeled, shorter than the glumes, 3-nerved, densely ciliate on nerves, often bearded at the apex. Palea equal to lemma, 2-nerved with short, dense hairs on nerves, the keels continued into minute points.
