Lower glume lateral veins absent, or distinct. Lower glume surface smooth to scabrous. Lower glume apex acute, or acuminate; muticous, or mucronate. Upper glume lanceolate; 5.5-20 mm long; 1.4 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume surface smooth to scabrous.
