HABIT Annual. Culms erect, or decumbent; 30–100 cm long; rooting from lower nodes. Ligule a ciliate membrane. Leaf-blades lanceolate, or ovate; 2.5–8.5 cm long; 10–20 mm wide. Leaf-blade apex acute, or acuminate.

INFLORESCENCE Inflorescence a panicle.

Panicle open; ovate; 6–9(–14) cm long. Panicle branches stiff; glandular.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; gibbous; 1.5–2 mm long; falling entire. Rhachilla internodes elongated between glumes.

Lower glume apex acute. Upper glume ovate; 1 length of spikelet; membranous; without keels; 5 -veined. Upper glume surface pilose. Upper glume apex acute.

FLORETS Basal sterile florets male; with palea. Lemma of lower sterile floret similar to upper glume; ovate; 1 length of spikelet; membranous; 5 -veined; acute. Fertile lemma oblong; dorsally compressed; 1–1.5 mm long; indurate; pallid; without keel. Lemma surface scaberulous. Lemma margins involute. Lemma apex obtuse. Palea involute; indurate.
