Lower glume primary vein ciliate. Lower glume apex truncate. Upper glume elliptic; 3.5–5.5 mm long; 1 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume primary vein ciliate. Upper glume apex truncate.

FLORETS Fertile lemma ovate; 3.5–5.5 mm long; membranous; keeled; 5 -veined. Lemma margins connate below. Lemma apex truncate; muticous, or awned; 1 -awned. Principal lemma awn dorsal; arising 0.5 way up back of lemma; 0–1.5 mm long overall. Palea absent or minute.
