Plants annual. Culms weak, sprawling. Ligules membranous, ciliate, very short. Panicles open, diffuse, lax, with a few spikelets. Spikelets warty-tuberculate or verrucose, faintly veined. Lower glumes less than 1/5 as long as the spikelets, without veins; upper glumes and lower lemmas subequal, 5-veined; lower florets sterile; lower paleas absent; upper florets finely longitudinally rugose, papillose and with bicellular microhairs, often with a minute protuberance at the base of the paleas. x = 9.
