GLUMES Glumes several; persistent; shorter than spikelet; thinner than fertile lemma. Lower glume ovate; scarious; without keels. Lower glume surface without pits. Upper glume oblong; scarious; without keels.
FLORETS Fertile lemma lanceolate, or oblong; coriaceous; without keel; wingless; 8–11 -veined. Lemma surface unwrinkled; without grooves. Lemma margins ciliate. Lemma apex acute; mucronate. Palea keels contiguous above a sulcus. Palea surface pilose. Apical sterile florets 1 in number; rudimentary.
