HABIT Annual. Culms geniculately ascending, or decumbent; slender; 10–100 cm long; with aerial roots from the nodes. Leaf-sheath auricles absent, or erect; 0–2 mm long. Ligule a ciliolate membrane. Leaf-blades 2–20 cm long; 1–7 mm wide. Leaf-blade surface ungrooved; scaberulous.
INFLORESCENCE Inflorescence a panicle.
Panicle spiciform; linear, or oblong; 1–13 cm long. Primary panicle branches accrescent to a central axis; with lateral stumps on axis. Panicle axis with rounded ribs.
Spikelets solitary. Fertile spikelets pedicelled.
FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; laterally compressed; gibbous; 2–3 mm long; falling entire.
GLUMES Glumes reaching apex of florets; thinner than fertile lemma. Lower glume ovate; 0.33–0.66 length of spikelet; hyaline; without keels; 3–5 -veined. Lower glume apex acute. Upper glume elliptic; gibbous; 1.3–2 length of adjacent fertile lemma; 1 length of spikelet; membranous; without keels; 5–7 -veined. Upper glume lateral veins ribbed. Upper glume surface glabrous, or pubescent. Upper glume apex acute.
FLORETS Basal sterile florets male, or barren; with palea. Lemma of lower sterile floret similar to upper glume; elliptic; 1 length of spikelet; membranous; 5–7 -veined; ribbed; glabrous, or pubescent; acute. Palea of lower sterile floret 0.1–0.2 length of lemma. Fertile lemma elliptic; dorsally compressed; 1–2 mm long; coriaceous; shiny; without keel; 5 -veined. Lemma margins involute. Lemma apex obtuse. Palea involute; coriaceous.
