HABIT Perennial; caespitose; clumped moderately, or densely. Culms 50–100 cm long; (2–)3 -noded. Culm-internodes distally pubescent. Leaf-sheaths puberulous; outer margin hairy. Ligule a ciliolate membrane; 0.5–7 mm long; pubescent on abaxial surface. Leaf-blades conduplicate; 23–52 cm long; 1–2 mm wide; grey-green. Leaf-blade surface pubescent; hairy adaxially. Leaf-blade apex attenuate.

INFLORESCENCE Inflorescence a panicle; comprising 5–7 fertile spikelets.

Panicle open, or contracted; linear, or lanceolate; 7.5–14 cm long; bearing few spikelets. Panicle branches bearded in axils (of lowest node).

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 60–70 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated.

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 surface pilose; hairy at base. Lower glume apex acuminate. Upper glume lanceolate; 60–70 mm long; membranous; without keels. Upper glume surface pilose; hairy at base. Upper glume apex acuminate.

FLORETS Fertile lemma lanceolate; subterete; 18–21 mm long; coriaceous; without keel; 5 -veined. Lemma margins convolute; covering most of palea; pubescent. Lemma apex awned; 1 -awned. Principal lemma awn bigeniculate; 260–420 mm long overall; with 195–320 mm long limb; with twisted column; limb plumose; with 4–5.5 mm long hairs. Column of lemma awn 70–100 mm long; scabrous. Palea without keels.

FRUIT Hilum linear.

DISTRIBUTION Europe: eastern.
