Primary panicle branches spreading; simple; 1-2 cm long; bearing 2-5 fertile spikelets on each lower branch; bearing spikelets almost to the base. Spikelets solitary. Fertile spikelets pedicelled.
- Spikelets
- Spikelets comprising 2 fertile florets; without rhachilla extension. Spikelets oblong; laterally compressed; 2-2.5 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 0.6-0.8 mm long.

Lower glume apex obtuse. Upper glume elliptic; 0.6-0.7 length of adjacent fertile lemma; membranous; without keels; 5 -veined. Upper glume apex obtuse.
- Florets
- Fertile florets with the lowest dissimilar. Lowest fertile lemma ovate; 1.1 length of adjacent lemma; firmer than adjacent lemma. Fertile lemma elliptic; 1.5-2 mm long; membranous; without keel; 0-3 -veined. Lemma surface pubescent. Lemma apex acute. Palea 1 length of lemma; 2 -veined. Palea surface pubescent.
