INFLORESCENCE Inflorescence composed of racemes.

Racemes 1–3(–4); digitate; unilateral; 0.7–1.5 cm long. Rhachis flattened. Spikelet packing broadside to rhachis; regular; 2 -rowed.

Spikelets appressed; solitary. Fertile spikelets sessile.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets ovate; laterally compressed; compressed strongly; 2.5 mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes persistent; similar; subequal in width; shorter than spikelet; thinner than fertile lemma. Lower glume lanceolate; 1 length of upper glume; herbaceous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 0.25–0.33 length of adjacent fertile lemma; herbaceous; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume apex acute.

FLORETS Fertile lemma lanceolate, or ovate; laterally compressed; 2.5 mm long; membranous, or cartilaginous; keeled; 3 -veined. Lemma midvein eciliate, or ciliate. Lemma apex acute. Palea 2 -veined. Palea keels eciliate.
