INFLORESCENCE Inflorescence a panicle; embraced at base by subtending leaf.

Panicle open; linear; 6–10 cm long.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 40–50 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; pubescent; acute.

GLUMES Glumes persistent; similar; exceeding apex of florets; thinner than fertile lemma. Lower glume lanceolate; 1 length of upper glume; membranous; without keels. Lower glume apex acuminate. Upper glume lanceolate; 40–50 mm long; membranous; without keels. Upper glume apex acuminate.

FLORETS Fertile lemma lanceolate; subterete; 12–14 mm long; coriaceous; without keel; 5 -veined. Lemma surface pubescent; hairy below; hairy in lines. Lemma margins convolute; covering most of palea. Lemma apex awned; 1 -awned. Principal lemma awn bigeniculate; 200–250 mm long overall; with twisted column; limb plumose; with 6–7 mm long hairs. Column of lemma awn 40–50 mm long; pubescent; with 1.5 mm long hairs. Palea without keels.
