Rhachis angular. Spikelet packing broadside to rhachis (1/1); lax. Spikelets solitary. Fertile spikelets pedicelled. Pedicels linear (1/1). FERTILE SPIKELETS Spikelets comprising 6-10 fertile florets; with diminished florets at the apex. Spikelets oblong (1), or obovate (1); laterally compressed; 4-6.81-9.6 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus pubescent (1), or bearded (1). GLUMES Glumes persistent; shorter than spikelet. Lower glume ovate; 0.5-0.58-0.66 length of upper glume; membranous; without keels; 0-2 -veined (1). Lower glume lateral veins absent (1), or distinct (1). Lower glume apex acute (1), or acuminate (1); muticous (1), or mucronate (1). Upper glume lanceolate, or ovate (1); 1-1.15-1.5 length of adjacent fertile lemma; membranous; 1-keeled (1/1); 3 -veined. Upper glume apex entire (1), or dentate (1); 2 -fid (1/1); acuminate (1/1); muticous (1), or awned (1); 1 -awned (1/1). FLORETS Fertile lemma lanceolate (1), or elliptic (1), or ovate (1); membranous; keeled (1/1); 3 -veined. Lemma lateral veins obscure (1/1). Lemma surface smooth (1), or scabrous (1). Lemma apex entire (1), or dentate (1); 2 -fid (1/1); acute; awned; 1 -awned. Principal lemma awn apical (1), or from a sinus (1). Palea 0.7-0.825-0.9 length of lemma; 2 -veined. Palea keels ciliolate (1), or ciliate (1). Apical sterile florets resembling fertile though underdeveloped. FLOWER Lodicules 2; membranous (1), or fleshy (1); truncate (1/1). Anthers 3.
