Culm about 30 cm tall. Blade linear-lanceolate, about 8 cm long by 4 mm wide, hirsute; sheath papillose-hispid. Inflorescence of racemes, 1-2 cm long. Spikelets paired; rachis-joint and pedicel grown together. Pedicellate spikelet conspicuous, staminate. Sessile spikelet fertile, about 1 mm long; lower glume globose, alveolate; upper glume broadly lanceolate, subcoriaceous, 3-nerved,margins infolded, appressed to the rachis-joint and pedicel which together form a cavity, as long as the spikelet. Florets hyaline.
