INFLORESCENCE Inflorescence a panicle.

Panicle open; ovate; 4.5–5 cm long; 1.3–2.5 cm wide. Primary panicle branches ascending. Panicle branches scaberulous.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform; terete; 1–2.7 mm long; scabrous.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 2.3–2.7 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus pubescent. Floret callus hairs 0.2 length of lemma.

GLUMES Glumes persistent; similar; exceeding apex of florets; firmer than fertile lemma; shiny; gaping. Lower glume lanceolate; 1.5–2.3 mm long; 1 length of upper glume; membranous; 1-keeled. Lower glume primary vein scaberulous. Lower glume apex acute. Upper glume lanceolate; 2.5–3 mm long; 1.2 length of adjacent fertile lemma; membranous; 1-keeled. Upper glume primary vein scaberulous. Upper glume apex acute.

FLORETS Fertile lemma ovate; 1.3–2.1 mm long; hyaline; without keel; 5 -veined. Lemma surface pilose. Lemma apex truncate; awned; 1 -awned. Principal lemma awn dorsal; arising 0.33 way up back of lemma; geniculate; 2–3 mm long overall; with twisted column. Palea absent or minute.
