Culm stout, about 45 cm long and 3 mm across. Blade about 7 mm wide; ligule about 1 mm long, ciliate on upper part and backside. Inflorescence a narrow panicle, about 10 cm long. Spikelets paired, dimorphic; the upper pedicellate, pedicel with a translucent longitudinal groove; the lower sessile and fertile, about 3.4 mm long, excluding the long awn. Lower glume subcoriaceous, lanceolate, acute, 3-nerved, about 3.2 mm long, margins inrolled; upper glume subcoriaceous, lanceolate, as long as the lower, 5-7-nerved, upper margins 2-keeled, hispid; upper lemma aristate, the awn 5 times the length of the lemma, flexuous, linear, 1-nerved, about 1.5 mm long; upper palea chartaceous, lanceolate, about 2.5 mm long, 2-nerved; anther about 1.2 mm long.
