Lower glume surface without pits. Lower glume apex acute. Upper glume ovate; 0.3–0.4–0.5 length of adjacent fertile lemma; 1-keeled; 1–3 -veined. Upper glume apex acute.

FLORETS Fertile lemma ovate; chartaceous; keeled; wingless; 3 -veined. Lemma surface smooth (1), or scaberulous (1); unwrinkled; without grooves; glabrous (1), or pubescent (1). Lemma apex acute; muticous (1), or mucronate. Palea 1 length of lemma; 1–2 -veined; 1-keeled. Palea surface glabrous (1), or pubescent (1).
