Lower glume apex obtuse. Upper glume elliptic; 1 mm long; 0.66 length of adjacent fertile lemma; membranous; without keels; 3 -veined. Upper glume apex obtuse.

FLORETS Fertile lemma oblong; 1.4–1.6 mm long; membranous; without keel; 5 -veined. Lemma lateral veins stopping well short of apex. Lemma apex obtuse. Palea 2 -veined. Palea keels scaberulous; adorned above. Apical sterile florets resembling fertile though underdeveloped.
