Leaf-blade surface scaberulous; glabrous.
INFLORESCENCE Inflorescence a panicle. Peduncle terete.
Panicle open, or contracted; pyramidal; 11–13 cm long; 1–2 cm wide; contracted about primary branches. Primary panicle branches ascending; 1 -nate; bearing spikelets almost to the base.
Spikelets solitary. Fertile spikelets pedicelled. Pedicels flexuous; 0.3–1.5 mm long.
FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets elliptic; subterete; 2–2.3 mm long; breaking up at maturity; disarticulating below each fertile floret.
GLUMES Glumes deciduous; similar; reaching apex of florets. Lower glume lanceolate; 1–1.2 mm long; 0 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 1.4–1.8 mm long; 0.8 length of spikelet; 1 -veined. Upper glume surface smooth; glabrous. Upper glume apex entire; acute.
FLORETS Fertile lemma lanceolate; 1.2–2.3 mm long; without keel; 1 -veined. Lemma apex entire. Palea readily splitting down midline; 0.8 length of lemma; 2 -veined. Palea apex entire; obtuse.
