HABIT Perennial; caespitose; clumped densely. Stolons absent. Culms 20–35 cm long. Culm-internodes distally glabrous. Lateral branches lacking. Leaf-sheaths open for most of their length; striately veined; pilose. Ligule a ciliolate membrane. Leaf-blades filiform; conduplicate; 0.3–0.7 mm wide. Leaf-blade venation with 7 secondary veins; 3 subepidermal sclerenchyma strands. Leaf-blade surface pilose; hairy abaxially.

INFLORESCENCE Inflorescence a panicle.

Panicle open; ovate; 4–6.5 cm long. Panicle branches pubescent.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 4–6 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 6.2–8 mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume oblong; 3.2–3.8 mm long; 0.75–0.85 length of upper glume; chartaceous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 3.9–4.5 mm long; 0.85–0.9 length of adjacent fertile lemma; chartaceous; without keels; 3 -veined. Upper glume apex acute.

FLORETS Fertile lemma elliptic; 4.6–5.1 mm long; chartaceous; without keel; 5 -veined. Lemma surface pilose; hairy above. Lemma apex acute; awned; 1 -awned. Principal lemma awn 2.8–4.8 mm long overall. Palea 4.4–5.2 mm long; 2 -veined. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Anthers 3; 3 mm long. Ovary pubescent on apex.

FRUIT Caryopsis with adherent pericarp; ellipsoid; 2.8–3 mm long. Hilum linear.

DISTRIBUTION Europe: central.
