Lower glume surface asperulous. Lower glume apex acuminate. Upper glume lanceolate, or ovate; 7–9 mm long; membranous; without keels; 5 -veined. Upper glume surface asperulous. Upper glume apex acuminate.
FLORETS Fertile lemma ovate; subterete; 5–6 mm long; membranous; dark brown; without keel; 7 -veined. Lemma surface pubescent. Lemma margins flat; covering most of palea. Lemma apex awned; 1 -awned.
