Ligule an eciliate membrane; 1–2 mm long; truncate. Leaf-blades 30–60 cm long; 4 mm wide; flaccid. Leaf-blade surface scaberulous; rough adaxially. Leaf-blade margins scaberulous. Leaf-blade apex acute.

INFLORESCENCE Dioecious. Inflorescence a panicle. Peduncle smooth, or scaberulous above.

Panicle open; ovate; 15–20 cm long; contracted about secondary branches. Primary panicle branches 5–7 -nate; whorled at most nodes; 6–12 cm long. Panicle axis scabrous. Panicle branches scabrous.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 3–4 fertile florets; with diminished florets at the apex. Spikelets ovate; laterally compressed; 5 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus woolly.

GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 3–3.5 mm long; 1 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume primary vein scaberulous. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 3–3.5 mm long; 0.66 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume primary vein scaberulous. Upper glume apex acute.

FLORETS Fertile florets female. Fertile lemma ovate; elliptic in profile; 4–4.5 mm long; membranous; keeled; 5 -veined. Lemma midvein ciliate; hairy below. Lemma lateral veins prominent. Lemma surface pubescent; hairy below; hairy on veins. Lemma apex acute. Palea keels scabrous; adorned above. Apical sterile florets resembling fertile though underdeveloped.
