INFLORESCENCE Inflorescence a panicle.

Panicle contracted; oblong; 6–8 cm long. Panicle branches scabrous.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 2–3 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 4.7–5.5 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes clavate; pilose; hairy above. Floret callus pubescent.

GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume elliptic; 3 mm long; 0.75–0.9 length of upper glume; membranous; 1-keeled; 3 -veined. Lower glume apex acuminate. Upper glume elliptic; 3.5–4 mm long; 0.75–0.9 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume apex acuminate.

FLORETS Fertile lemma oblong; 4.6–4.7 mm long; membranous; keeled; 5 -veined. Lemma apex dentate; 2 -fid; muticous, or awned; 1 -awned. Principal lemma awn from a sinus; 0–0.5 mm long overall. Palea 3.5 mm long; 2 -veined. Palea keels scaberulous. Apical sterile florets resembling fertile though underdeveloped.
