Lower glume apex obtuse. Upper glume ovate; 0.05–0.3 length of adjacent fertile lemma; hyaline; without keels; 1 -veined. Upper glume apex obtuse.
FLORETS Fertile lemma oblong; hyaline; without keel; wingless; 3 -veined. Lemma lateral veins obscure. Lemma surface unwrinkled; without grooves. Lemma apex erose; truncate. Palea hyaline; 2 -veined.
