    Spikelets
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 2.5-3.2 mm long; falling entire.
    Fertile

Lower glume lateral veins absent. Lower glume margins ciliate. Lower glume apex acute. Upper glume lanceolate; 2.5-3.2 mm long; 1 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume margins ciliate. Upper glume apex acute.
    Florets
    Fertile lemma lanceolate; laterally compressed; 2.5-3.2 mm long; membranous; keeled; 1 -veined. Lemma apex acute. Palea 2 -veined.
    Flowers

    Inflorescences
    Inflorescence 0.3–1.5 cm long, ovoid, almost wholly embraced by the uppermost leaf sheaths.
    Spikelets
    Spikelets 2.5–3.2 mm long, lanceolate, readily deciduous; glumes subequal, as long as the lemma, the inferior pilose on the margins; lemma as long as the spikelet, lanceolate; palea 2-nerved; anthers 0.5–0.9 mm long.
