Awn of upper sterile floret dorsal; arising 0.5 way up back of lemma; geniculate; 4-5.5 mm long. Fertile lemma oblong; 3 mm long; cartilaginous; without keel; 5 -veined. Lemma lateral veins obscure. Lemma margins convolute; covering most of palea. Lemma apex emarginate; muticous, or mucronate. Palea oblong; 3 mm long; 1 length of lemma; 1 -veined; without keels.
