HABIT Perennial; caespitose. Culms 40–60 cm long. Leaf-sheaths glabrous on surface to pubescent. Ligule a ciliolate membrane; 1–1.2 mm long; pubescent on abaxial surface. Leaf-blades conduplicate; 30–60 cm long; 0.7–0.8 mm wide. Leaf-blade venation with 9 inner ridges. Leaf-blade surface ribbed; scabrous; rough abaxially; puberulous. Leaf-blade apex hairy.

INFLORESCENCE Inflorescence a panicle.

Panicle open; bearing few spikelets.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 30–50 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; 30–50 mm long; membranous; without keels. Upper glume apex acuminate.

FLORETS Fertile lemma lanceolate; subterete; 17–18 mm long; coriaceous; without keel; 5 -veined. Lemma margins convolute; covering most of palea. Lemma apex dentate; 2 -fid; awned; 1 -awned. Principal lemma awn from a sinus; bigeniculate; 195–210 mm long overall; with twisted column; limb plumose; with 4 mm long hairs. Middle segment of lemma awn puberulous. Palea without keels.
