Lower glume surface without pits. Lower glume apex acuminate. Upper glume lanceolate; 2 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume apex acuminate.

FLORETS Fertile lemma oblong; membranous; keeled; wingless; 3 -veined. Lemma surface unwrinkled; without grooves. Lemma margins ciliate. Lemma apex dentate; 2 -fid; truncate; awned; 1 -awned. Principal lemma awn from a sinus; curved. Palea 1 length of lemma; 2 -veined. Palea keels scaberulous. Apical sterile florets resembling fertile though underdeveloped.
