INFLORESCENCE Inflorescence a panicle.

Panicle open; oblong; 2–5 cm long; 1–2.5 cm wide.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels oblong.

FERTILE SPIKELETS Spikelets comprising 2 fertile florets; without rhachilla extension. Spikelets ovate; laterally compressed; 1.5 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 0.5 mm long.

Lower glume elliptic, or orbicular; 0.25 mm long; 0.5 length of upper glume; 0.1 length of spikelet; membranous; without keels; 0 -veined. Lower glume lateral veins absent. Lower glume apex truncate. Upper glume elliptic, or orbicular; 0.5 mm long; 0.25 length of spikelet; membranous; without keels; 1–2 -veined. Upper glume apex obtuse.

FLORETS Fertile florets female (upper); with the lowest dissimilar. Lowest fertile lemma bisexual; elliptic; 1.25 mm long; 1.75 length of adjacent lemma; firmer than adjacent lemma; hairy. Fertile lemma elliptic; 0.7 mm long; hyaline; without keel; 0 -veined. Lemma apex acute. Palea 1 length of lemma.
