Lower glume apex acute. Upper glume lanceolate; 4–6 mm long; 0.7–0.8 length of adjacent fertile lemma; hyaline; without keels; 3 -veined. Upper glume apex acute; mucronate.

FLORETS Fertile lemma oblong; 7–8 mm long; membranous; much thinner above; much thinner on margins; without keel; 5–7 -veined. Lemma apex obtuse, or acute; mucronate. Palea 2 -veined. Palea keels scabrous. Apical sterile florets resembling fertile though underdeveloped.
