INFLORESCENCE Inflorescence a panicle; embraced at base by subtending leaf.
Panicle contracted; linear; 17–25 cm long.
Spikelets solitary. Fertile spikelets pedicelled.
FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 20–22 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; 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; 20–22 mm long; membranous; without keels. Upper glume apex acuminate.
FLORETS Fertile lemma lanceolate; subterete; 10 mm long; coriaceous; without keel; 5 -veined. Lemma surface pubescent; hairy below; hairy in lines. Lemma margins convolute; covering most of palea. Lemma apex surmounted by a ring of hairs; awned; 1 -awned. Principal lemma awn bigeniculate; 150–180 mm long overall; with twisted column; limb pubescent; with 0.3–0.5 mm long hairs. Palea without keels.
