Culms stout, solid, juicy, up to 3 m high, white silky hairy below the inflorescence. Blade glabrous, 4-6 cm wide, midrib stout and white; ligule membranous, truncate, about 2 mm long; sheath longer than the internode, imbricate. Panicle very large, about 60 cm long, main axis white, silky-hairy; rachis and pedicel swollen at the tip; margins of the rachis long, ciliated, 6-10 mm long; pedicel glabrous, 3-4 mm long. Spikelets paired, monomorphic, the one pedicellate and the other sessile; sessile spikelet about 4.5 mm long; callus silvery, long soft hairy, the hairs 2-3 times as long as the spikelet; lower glume lanceolate., margins membranous and ciliate, 2-keeled, 4-nerved; upper glume 3-nerved, boat-shaped; lower lemma 1-nerved, oblong-lanceolate; upper lemma about 3 mm long; upper palea about 2 mm long; anthers about 1.5 mm long.
