INFLORESCENCE Inflorescence a panicle.
Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform.
FERTILE SPIKELETS Spikelets comprising 5–10 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 10–20 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite. Floret callus elongated; pilose.
GLUMES Glumes persistent; shorter than spikelet. Lower glume lanceolate; 0.75 length of upper glume; membranous; 1-keeled; 1–3 -veined. Lower glume surface without pits. Lower glume apex acuminate. Upper glume lanceolate; 0.7 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume apex acuminate.
FLORETS Fertile lemma lanceolate; membranous; keeled; wingless; 3 -veined. Lemma surface unwrinkled; without grooves. Lemma margins ciliate. Lemma apex acute; awned; 1 -awned. Palea 0.8 length of lemma; 2 -veined. Palea keels ciliate. Apical sterile florets resembling fertile though underdeveloped.
