Lower glume intercarinal veins absent. Lower glume surface concave; impressed with a boss blocking lower end. Upper glume lanceolate; 1-keeled. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets barren; without significant palea. Lemma of lower sterile floret hyaline. Fertile lemma lanceolate; hyaline; without keel. Lemma apex lobed; 2 -fid; awned; 1 -awned. Principal lemma awn from a sinus; geniculate; 16 mm long overall; with twisted column. Column of lemma awn glabrous. Palea absent or minute.
