Bud complement 1. Branch complement several; in a clump; thinner than stem. Culm-sheaths deciduous; green, or purple; pilose; with purple hairs; without auricles. Culm-sheath ligule 0.5 mm high; ciliolate. Culm-sheath blade lanceolate; narrower than sheath; deciduous; spreading, or reflexed; 3 cm long; 2–3 mm wide; acuminate. Leaves 6–10 per branch. Leaf-sheath oral hairs setose. Ligule absent. Leaf-blades lanceolate; 9–18 cm long; 10–17 mm wide. Leaf-blade midrib prominent beneath. Leaf-blade venation without cross veins. Leaf-blade margins unthickened; smooth, or scaberulous. Leaf-blade apex acuminate.

INFLORESCENCE Inflorescence a panicle.

Panicle open; ovate; 15–20 cm long; 8–10 cm wide. Panicle branches glabrous; with prominent pulvini.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels 7–8 mm long.

FERTILE SPIKELETS Spikelets comprising 5–7 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 25–35 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes pubescent.

GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume ovate; 3.8–5.6 mm long; chartaceous; without keels; 5 -veined. Lower glume margins ciliolate. Lower glume apex acute. Upper glume ovate; 5.5–6.1 mm long; chartaceous; without keels; 7 -veined. Upper glume margins ciliolate. Upper glume apex acute.

FLORETS Fertile lemma ovate; 8.5–10 mm long; chartaceous; without keel; 5 -veined. Lemma lateral veins with cross-veins. Lemma apex apiculate. Palea keels contiguous above a sulcus; winged. Palea surface scabrous. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Lodicules 3; 1.5–2 mm long; veined; ciliate. Anthers 3; 4.3–6 mm long; orange.
