Lower glume apex obtuse. Upper glume oblong; 1 length of spikelet; coriaceous; dark brown, or red; without keels. Upper glume surface pilose. Upper glume apex obtuse.

FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret oblong; 1 length of spikelet; hyaline; 0 -veined; without midvein; without lateral veins; ciliate on margins; obtuse. Fertile lemma oblong; 2–3 mm long; hyaline.
