Lower glume surface without pits. Lower glume apex acute. Upper glume ovate; 0.75 length of adjacent fertile lemma; hyaline; 1-keeled; 1 -veined. Upper glume apex acute.
FLORETS Fertile lemma oblong; membranous; much thinner above; keeled; wingless; 3 -veined. Lemma lateral veins obscure; less than two thirds length of lemma. Lemma surface scaberulous; unwrinkled; without grooves. Lemma apex obtuse. Palea 1 length of lemma; 2 -veined. Palea keels scaberulous.
