    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; compressed slightly; acute; 3-4.5 mm long; falling entire.
    Glume
    Glumes dissimilar; reaching apex of florets; thinner than fertile lemma. Lower glume ovate; 0.5 length of spikelet; membranous; without keels; 5 -veined. Lower glume lateral veins ribbed. Lower glume surface pubescent; with clavate hairs. Lower glume apex acute. Upper glume ovate; 1 length of spikelet; membranous; without keels; 7 -veined. Upper glume lateral veins ribbed. Upper glume surface pubescent; with clavate hairs. Upper glume apex acute.
    Florets
    Basal sterile florets male; with palea. Lemma of lower sterile floret similar to upper glume; ovate; 1 length of spikelet; membranous; 7 -veined; ribbed; pilose; with clavate hairs; acute. Palea of lower sterile floret pubescent. Fertile lemma elliptic; 2.5-4 mm long; coriaceous; without keel. Lemma surface striate. Lemma margins involute. Lemma apex apiculate; pubescent. Palea involute; coriaceous; without keels.
