Upper glume surface pubescent. Upper glume apex acute.

FLORETS Fertile lemma oblong; 2 mm long; chartaceous; without keel; 9 -veined. Lemma surface villous; hairy below. Lemma apex dentate; 9 -fid; awned; 9 -awned. Principal lemma awn 2–3.5 mm long overall; limb ciliate. Lateral lemma awns arising on apex of lobes; subequal to principal; ciliate. Palea keels ciliolate. Apical sterile florets 2 in number; dissimilar. First apical floret male; oblong; villous. Apical sterile florets barren; rudimentary. Apical sterile lemmas awned; 9 -awned. Apical sterile lemma awns ciliate.
