Spikelets solitary. Fertile spikelets sessile.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 4–6 mm long; falling entire.

GLUMES Glumes similar; shorter than spikelet. Lower glume lanceolate; 3.5–4.8 mm long; 0.9 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume primary vein ciliolate. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 3.5–4.8 mm long; 0.75–0.9 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume primary vein ciliolate. Upper glume lateral veins absent. Upper glume apex acute.

FLORETS Fertile lemma lanceolate; laterally compressed; 4.5–5.2 mm long; membranous; keeled; 1 -veined. Lemma apex acute. Palea 2 -veined.

FLOWER Lodicules absent. Anthers 3; 2–3 mm long.
