INFLORESCENCE Inflorescence a panicle.

Panicle open; linear; secund; 7–20 cm long. Primary panicle branches indistinct the panicle almost racemose.

FERTILE SPIKELETS Spikelets comprising 2 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 5–9(–11) mm long; falling entire.

GLUMES Glumes similar; reaching apex of florets; thinner than fertile lemma. Lower glume elliptic; 4–8 mm long; 0.8 length of upper glume; membranous; without keels; 5 -veined. Lower glume apex acute. Upper glume elliptic; 5–9 mm long; 1 length of adjacent fertile lemma; membranous; without keels; 5 -veined. Upper glume apex acute.

FLORETS Fertile lemma elliptic; 4–8 mm long; chartaceous; without keel; 5 -veined. Lemma margins ciliate. Lemma hairs 2 mm long. Lemma apex obtuse. Palea 2 -veined. Apical sterile florets 2–3 in number; barren; in a clump; cuneate. Apical sterile lemmas glabrous.
