INFLORESCENCE Inflorescence a panicle. Peduncle 3–10 cm long.

Panicle spiciform; linear; 6–12 cm long; 0.3–0.5 cm wide. Primary panicle branches accrescent to a central axis; with lateral stumps on axis. Panicle axis with rounded ribs.

Lower glume apex obtuse, or acute. Upper glume lanceolate, or ovate; gibbous; 1 length of spikelet; membranous; without keels; 5–7 -veined. Upper glume lateral veins ribbed. Upper glume apex acute.

FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret similar to upper glume; lanceolate, or ovate; 1 length of spikelet; membranous; 5–7 -veined; ribbed; acute.
