Leaves ± adpressed whitish-pilose on both surfaces; basal leaves spathulate, 15-70 x 5-10 mm, obtuse at apex, attenuate at base, entire; cauline leaves smaller, 1-3 cm long, linear-lanceolate or oblanceolate, acute. Capitula solitary. Involucre 1.25-1.75 cm broad; phyllaries 2-seriate, linear, obtuse or broadly acute, 7-8 x 0.75-1 mm, green with narrow whitish margins, sparsely pubescent at apices, strongly ciliate. Ray flowers 30-40, blue or lilac; ligules 10-15 x 1-3 mm. Disc flowers 5-6 mm. Achenes 2-3 mm, densely sericeous. Pappus 2-seriate, whitish (turning brown with storage), 4.5-6 mm with a few shorter outer hairs. Fl. 6-8. On limestone or granite rock ledges, screes and north-facing corries, 1800-3080 m.   Described from Europe (Hb. Linn. 997/10!).   N., S. & Inner Anatolia.

Bot. 106:21, 1932) recognized two ill-defined varieties in Turkey, the chief distinction between which appears to be one of size: var. dolomiticus Beck with taller stems (6-20 cm) and larger capitula (1.5-2 cm broad), and var. cylleneus Boiss. & Orph. with shorter stems (5-10 cm) and smaller capitula (1-1.5 cm broad). These are treated here as extremes of a variable species.
