Perennials, 30-130 cm (taproots stout, caudices branched). Stems 1, erect, branched distally, setulose and sometimes glandular proxi-mally. Leaves mostly cauline; petiolate or sessile; blades broadly oblanceolate to elliptic, 15-30 × 4-6 cm, margins closely toothed (teeth corneous apically and sometimes along margins), apices acute, faces scabrous, ± setulose and stipitate-glandular; (cauline sessile, ovate or elliptic, bases auriculate). Heads 1-8, borne singly or (on racemiform branches) in compound, paniculiform or corymbiform arrays. Calyculi of 10-12, lanceolate to linear, sparsely tomentulous bractlets 3-5 mm. Involucres cylindro-campanulate, 10-15 × 6-12 mm. Phyllaries 12-15, lanceolate, 9-10 mm, (bases strongly thickened, margins green), apices (dark) acute, abaxial faces tomentulose, sometimes with setae, adaxial glabrous. Florets 50-90; corollas yellow, 15-18 mm (sparsely tomentulose). Cypselae brown, fusiform, 5-6 mm, apices narrowed (not beaked), ribs 15-20; pappi white (soft), 5-8 mm. 2n = 8.

Flowering Jun-Aug. Dry, open, grassy areas, pastures; 1000-2000 m; introduced; Conn.; Europe.

Crepis pannonica is recognized by its leafy, erect stems, broadly elliptic or obovate leaves with closely dentate margins, auriculate distal leaves, and tomentulose phyllaries.
