Upper glume ovate; 0.4–0.5 length of adjacent fertile lemma; chartaceous; without keels; 7 -veined. Upper glume apex acute.
FLORETS Basal sterile florets male, or barren; with palea. Lemma of lower sterile floret ovate; 0.9 length of fertile lemma; chartaceous; 7 -veined; acuminate. Fertile lemma lanceolate; laterally compressed; coriaceous; without keel; wingless; 5 -veined. Lemma surface unwrinkled; without grooves; glabrous, or pubescent. Lemma margins involute; ciliolate.
