INFLORESCENCE Inflorescence a panicle.

Panicle open; linear; 3–8 cm long. Primary panicle branches indistinct the panicle almost racemose.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong, or ovate; laterally compressed; 6 mm long; breaking up at maturity; disarticulating below each fertile floret.

Lower glume apex acute. Upper glume oblong; 4 mm long; 0.66 length of spikelet; chartaceous; without keels; 5 -veined. Upper glume apex acute.

FLORETS Basal sterile florets similar; barren; without significant palea; attached to and deciduous with the fertile. Lemma of lower sterile floret oblong, or ovate; 6 mm long; 1 length of spikelet; cartilaginous; 1-keeled; 5 -veined; smooth; obtuse. Lemma of upper sterile floret oblong, or ovate; 6 mm long; 1 length of lower sterile floret; cartilaginous; obtuse. Fertile lemma oblong; 5 mm long; coriaceous; keeled; 9 -veined. Lemma apex obtuse.
