    Habit
    Perennial. Culms erect; 50-60 cm long. Culm-internodes distally glabrous, or pubescent. Leaves cauline. Leaf-sheaths pubescent. Leaf-sheath oral hairs setose. Ligule an eciliate membrane. Leaf-blade base with a brief petiole-like connection to sheath; petiole 0.5-0.7 cm long; petiole pubescent. Leaf-blades lanceolate; 13-25 cm long; 40-60 mm wide. Leaf-blade surface pubescent; hairy adaxially (on midrib). Leaf-blade apex acute.
    Inflorescences
    Monoecious; with male and female spikelets in the same inflorescence. Synflorescence on a separate leafless culm. Inflorescence composed of racemes. Racemes 1; single; erect; multilateral; 6 cm long; 7-9 mm wide. Rhachis fragile at the nodes; terminating in a sterile spikelet. Rhachis internodes linear. Sexes mixed (in a cluster at each node). Spikelets subtended by an involucre. Fertile spikelets sessile; 1 in the cluster. Male spikelets pedicelled; 5 in a cluster. Involucre composed of imperfect spikelets; with pedicels forming a cup; oblong. Pedicels fused to each other; united along margins; oblong; flattened; 3-4 mm long; pubescent; hairy at base; tip rectangular.
    Spikelets

Lower glume apex acuminate. Upper glume lanceolate; 7 mm long; 1.4 length of adjacent fertile lemma; chartaceous; 1-keeled. Upper glume surface pubescent. Upper glume apex acuminate.
    Florets
