Upper glume oblong; 0.5-0.625-0.75 length of adjacent fertile lemma; coriaceous; with membranous margins; 2-keeled; 2-5 -veined (1). Upper glume primary vein eciliate (1), or ciliate (1). Upper glume lateral veins convergent at apex. Upper glume surface glabrous (1), or pilose (1); without hair tufts (1), or with tufts of hair along primary vein (1). Upper glume apex truncate, or obtuse (1); awned; 1 -awned. FLORETS Fertile lemma lanceolate, or oblong (1); coriaceous; keeled; 5 -veined. Lemma midvein eciliate (1), or ciliate (1).
