Description
Erianthus are "coarse perennials from hardened bases or short rhizomes; culms usually purplish, nodes usually, glabrous or upper appressed pubescent, internodes usually glabrous. Leaves primarily cauline; blades scaberulous, usually densely long hirsute above ligule; sheaths usually glabrous; ligules membranous, ciliate, 1-4 mm long; collars long-hirsute. Panicle solitary, terminal, ovoid to ellipsoid. Racemes numerous, most ascending, joints and pedicels subequal, 2-6 mm long, scaberulous or villous. Spikelets in pairs, fertile, sessile and pedicellate, yellowish to purplish, ovoid. Glumes cartilaginous, acuminate, subequal; lemmas and paleas hyaline to purplish, shorter than glumes; callus usually bearded. Grain reddish, ellipsoid, 2-3.5 mm long." - Radford et al 1964.
Specifically, Erianthus alopecuroides have "culms to 3 m tall. Blades to 7.5 dm long and 3 cm wide. Panicle whitish to tawny, 1.5-3 dm long, 5-12 cm broad; rachis long villous. Spikelets villous, 6-8 mm long, awns twisted, flat, 10-16 mm long; callus beard exceeding spikelet. Grain 2.5 mm long." - Radford et al 1964.
