Spikelet callus bearded; base obtuse; attached transversely. Spikelet callus hairs 0.2-0.33 length of spikelet.
    Glume
    Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume elliptic; 1 length of spikelet; chartaceous; 2-keeled; keeled above; 2 -veined. Lower glume surface flat, or concave; pilose; hairy below. Lower glume margins ciliate. Lower glume hairs white, or yellow. Upper glume elliptic; 1 length of spikelet; 3 -veined. Upper glume surface pilose. Upper glume margins ciliate. Upper glume apex obtuse; muticous.
