Lower glume surface without pits. Lower glume apex acuminate. Upper glume linear; 0.75–1 length of adjacent fertile lemma; herbaceous; 1-keeled; 3–5 -veined. Upper glume apex acuminate.
FLORETS Fertile lemma lanceolate; subterete; coriaceous; without keel; wingless; 5 -veined. Lemma surface unwrinkled; without grooves. Lemma margins convolute; covering most of palea. Lemma apex acuminate; awned; 1 -awned. Principal lemma awn flexuous. Palea coriaceous. Apical sterile florets 1 in number; barren; rudimentary. Apical sterile lemmas awned.
