Lower glume apex acuminate; awned. Upper glume lanceolate; 0.6–0.9 length of adjacent fertile lemma; chartaceous; 1-keeled; 7–9 -veined. Upper glume apex acuminate; awned; 1 -awned.

FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret elliptic; chartaceous; 7 -veined; acuminate; awned. Fertile lemma ovate; laterally compressed; chartaceous; keeled; wingless; 13 -veined. Lemma midvein pubescent. Lemma surface unwrinkled; without grooves. Lemma margins pubescent. Lemma apex acuminate. Palea chartaceous; 8 -veined. Palea keels approximate; pubescent. Palea surface pubescent.
