Spikelets solitary. Fertile spikelets sessile.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 4–5 mm long; falling entire.

GLUMES Glumes similar; reaching apex of florets. Lower glume lanceolate; 4–5 mm long; 1 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume primary vein scaberulous. Lower glume lateral veins absent. Lower glume margins eciliate, or ciliolate. Lower glume apex acute. Upper glume ovate; 4–5 mm long; 1 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume primary vein scaberulous. Upper glume lateral veins absent. Upper glume surface glabrous, or puberulous. Upper glume margins ciliolate. Upper glume apex obtuse, or acute.

FLORETS Fertile lemma ovate; laterally compressed; 4–5 mm long; membranous; keeled; 1 -veined. Lemma apex acute. Palea 3–4 mm long; 2 -veined.
