Lower glume surface without pits. Lower glume apex acute. Upper glume elliptic; 0.75–1 length of adjacent fertile lemma; membranous; without keels; 5 -veined. Upper glume apex acute.
FLORETS Fertile lemma elliptic; scarious; without keel; wingless; 7 -veined. Lemma surface smooth, or granulose; unwrinkled; without grooves. Lemma apex erose; acute. Apical sterile florets resembling fertile though underdeveloped.
