Culm long creeping. Blade about 20 cm long by 5 mm wide, subulate; ligule about 0.8 mm long, chartaceous, truncate and minutely ciliate on backside. Inflorescence a spike; spikelets sunken in a cavity of the rachis joint. Spikelets 2-flowered, about 12 mm long; rachis joints about 4 mm long; lower glume deltoid, membranous; margins minutely scabrid, about 0.8 mm long; upper glume coriaceous, about 12 mm long, lanceolate, aristate, margins membranous and inrolled; lemma subcoriaceous, about 4.5 mm long, broadly lanceolate, 3-nerved, lateral nerves close to margin, acute, basal part minutely bearded; palea elliptical, subcoriaceous, as long as the lemma; anther about 2 mm long. Caryopsis about 6 mm long, oblong; embryo 1/2 the length of the caryopsis.
