GLUMES Glumes several; comprising 9 gemmiferous bracts; 0–1 empty glumes; persistent; similar; shorter than spikelet.

FLORETS Fertile lemma ovate; 12 mm long; chartaceous; without keel. Lemma lateral veins prominent; with cross-veins. Lemma margins eciliate. Lemma apex obtuse, or acute. Palea inturned at apex.
