Leaf-blades 1–12 cm long; 2–4 mm wide. Leaf-blade surface pubescent. Leaf-blade margins scaberulous.

INFLORESCENCE Inflorescence a panicle.

Panicle spiciform; oblong; 2.7–3.5 cm long; 1.5–2.5 cm wide. Primary panicle branches accrescent to a central axis; with lateral stumps on axis. Panicle axis pubescent.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels cuneate; 0.25–0.7 mm long; tip oblique.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; 7.4–12 mm long; falling entire. Spikelet callus bearded. Spikelet callus hairs 0.5 length of spikelet.

GLUMES Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume ovate; 0.8–1 length of spikelet; membranous; without keels; 5–7 -veined. Lower glume lateral veins ribbed. Lower glume margins setose (above). Lower glume apex acuminate; awned; 1 -awned. Lower glume awn 1–1.5 mm long. Upper glume ovate; 7.4–12 mm long; coriaceous; much thinner above; without keels; 11–13 -veined. Upper glume surface pubescent; hairy below. Upper glume margins ciliate. Upper glume apex acuminate; awned; 1 -awned. Upper glume awn 0.35–2.5 mm long.

FLORETS Basal sterile florets male; with palea. Lemma of lower sterile floret ovate; gibbous; 5.5–7 mm long; 0.75 length of spikelet; coriaceous; much thinner above; 7 -veined; ribbed; puberulous; acute. Fertile lemma ovate; 5.5–7 mm long; cartilaginous; much thinner above; without keel; 5–7 -veined. Lemma apex rostrate. Palea 1 length of lemma; cartilaginous; 2 -veined.
