Lower glume apex obtuse. Upper glume lanceolate; 1.3–2 mm long; 0.66 length of adjacent fertile lemma; membranous; without keels; 1 -veined. Upper glume lateral veins absent. Upper glume apex obtuse.
FLORETS Fertile lemma ovate; 2–2.5 mm long; membranous; without keel. Lemma surface scabrous; rough on veins. Lemma apex obtuse. Palea bowed outwards; 1 length of lemma; 2 -veined. Apical sterile florets resembling fertile though underdeveloped.
