Koeleria lucana

HABIT Perennial; caespitose; clumped densely. Culms erect; 20–50 cm long. Leaves mostly basal. Leaf-sheaths 4–4.5 cm long; pubescent; outer margin hairy. Ligule a ciliolate membrane. Leaf-blades 4–12 cm long; 1.4–2.2 mm wide. Leaf-blade surface pubescent; hairy on both sides. Leaf-blade margins ciliate.

INFLORESCENCE Inflorescence a panicle.

Panicle spiciform; oblong; continuous; 4–8 cm long; 0.7–1.2 cm wide. Panicle axis puberulous. Panicle branches puberulous.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 3 fertile florets; with diminished florets at the apex. Spikelets oblong, or cuneate; laterally compressed; 6–7(–7.5) mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes persistent; similar; shorter than spikelet, or reaching apex of florets; similar to fertile lemma in texture; shiny. Lower glume oblong; 5–6 mm long; 1 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume primary vein scabrous. Lower glume lateral veins absent. Lower glume apex acute, or acuminate. Upper glume oblong; 5–6 mm long; 1 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume primary vein scabrous. Upper glume apex acute, or acuminate.

FLORETS Fertile lemma oblanceolate; 4.8–6 mm long; 1.3–2 mm wide; membranous; shiny; keeled; 3 -veined. Lemma midvein scabrous. Lemma surface glabrous. Lemma apex acute, or acuminate; muticous. Palea gaping; oblong; 4.5–5.5 mm long. Palea apex dentate; 2 -fid. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Lodicules 2; oblong; 0.8–1 mm long; membranous; 2-toothed. Anthers 3; 2.5–2.7 mm long.

DISTRIBUTION Europe: southeastern.
