Culm-sheaths glabrous. Leaves cauline. Leaf-sheaths glabrous on surface, or puberulous. Leaf-sheath oral hairs ciliate; pale. Ligule an eciliate membrane. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades lanceolate; 15–25 cm long; 15–22 mm wide. Leaf-blade surface glabrous, or pubescent; hairy abaxially.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 8–12 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 60–110 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 4–6 mm long; pubescent.

GLUMES Glumes one the lower absent or obscure, or one to two the lower present in some spikelets; persistent; similar; shorter than spikelet. Lower glume lanceolate; 3–4 mm long; chartaceous; without keels; 0 -veined. Lower glume lateral veins absent. Upper glume lanceolate, or ovate; 8–10 mm long; chartaceous; 5–7 -veined.

FLORETS Fertile lemma lanceolate; 10–18 mm long; chartaceous; without keel; 11–13 -veined. Lemma lateral veins with cross-veins. Lemma apex acuminate. Palea 11–13 mm long; 8–10 -veined. Palea keels ciliate. Apical sterile florets resembling fertile though underdeveloped.
