Lower glume lanceolate; 0.8 length of upper glume; chartaceous; 1-keeled; 5-7 -veined. Lower glume apex attenuate. Upper glume lanceolate; 2 length of adjacent fertile lemma; chartaceous; with hyaline margins; 1-keeled; 7-9 -veined. Upper glume apex setaceously attenuate. FLORETS Fertile lemma lanceolate; coriaceous; without keel; 7-9 -veined. Lemma surface pilose. Lemma apex lobed; 2 -fid; incised 0.3 of lemma length; awned; 1 -awned. Principal lemma awn from a sinus; geniculate. Palea 0.6 length of lemma; 2 -veined. Palea keels winged. Apical sterile florets resembling fertile though underdeveloped.
