Lower glume apex acuminate. Upper glume lanceolate; 11–12 mm long; 0.66 length of adjacent fertile lemma; membranous; without keels; 3 -veined. Upper glume apex acuminate.

FLORETS Fertile lemma lanceolate; 16–20 mm long; chartaceous; much thinner on margins; without keel; 5–7 -veined. Lemma apex dentate; 2 -fid; awned; 1 -awned. Principal lemma awn subapical; 10 mm long overall. Apical sterile florets resembling fertile though underdeveloped.
