Rhizome well developed; culm up to 1.5 m high. Blade farinose and usually covered with soft hairs, up to 40 cm long by 1 cm wide; ligule rounded, ciliated at the apex, 1-2 cm long. Panicle about 35 cm long; main axis hairy, fan-shaped, branches erect, up to 25 cm long; rachis-joints 5-10 mm long; pedicels one longer and the other shorter. Spikelets paired, all pedicellate, monomorphic, lanceolate, about 4.5-5 mm long; callus of silky hairs, the hairs nearly equaling the spikelet; lower glume acuminate, 3-nerved, margins keeled, glabrous; upper glume boat-shaped, acuminate, margins ciliate; lower lemma oblong-lanceolate, obtuse; upper lemma about 2/3 as long as the spikelet, deeply 2-cleft, with a geniculate awn, protruding from the sinus, awn about 10 mm long; upper palea 1/2 as long as the lemma, toothed at the apex.
