HABIT Perennial; caespitose. Butt sheaths pubescent. Culms 30–50 cm long. Culm-internodes distally pubescent. Leaf-sheaths antrorsely scabrous. Ligule a ciliolate membrane; 2–5 mm long; 1 mm long on basal shoots. Leaf-blades conduplicate; 1–2 mm wide. Leaf-blade surface ribbed; with rectangular ribs; smooth; pubescent; sparsely hairy; hairy adaxially. Leaf-blade apex acuminate; antrorsely scabrous.

INFLORESCENCE Inflorescence a panicle; comprising 3–8 fertile spikelets. Peduncle pubescent above.

Panicle contracted; linear; bearing few spikelets.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 30–60 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; pilose; 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; 30–60 mm long; membranous; without keels. Upper glume apex acuminate.

FLORETS Fertile lemma lanceolate; subterete; 19–21 mm long; coriaceous; without keel; 5 -veined. Lemma margins convolute; covering most of palea. Lemma apex awned; 1 -awned. Principal lemma awn bigeniculate; 250–270 mm long overall; with twisted column; limb plumose; with 5 mm long hairs. Palea without keels.
