Lower glume lateral veins absent. Lower glume surface without pits. Lower glume apex acuminate. Upper glume lanceolate; 2 length of adjacent fertile lemma; membranous; without keels; 3 -veined. Upper glume apex acute.
FLORETS Fertile lemma ovate; dorsally compressed; coriaceous; without keel; wingless; 3 -veined. Lemma midvein pubescent. Lemma surface unwrinkled; without grooves. Lemma margins ciliate. Lemma apex obtuse; awned; 1 -awned. Apical sterile florets 1 in number; barren; oblong.
