Tap-rooted perennial, 5-50 cm, with shortly branched caudex sheathed in old stipules. Leaves mostly basal, 1,5-5 cm diam., palmatifid to c. ½ ; segments broadly cuneate, apically 2-6-lobed. Stems 1-12-flowered, often crisply pubescent, procumbent or ascending, rarely erect, often leafless when the long peduncles arise from the basal rosettes. Sepals 6-12 mm, adpressed-pubescent and ± pilose. Petals broadly obovate, emarginate, 13-18 mm, pink, purple or white. Mericarps pilose. Subsp. cinereum grown in the Pyrenees, and several closely related taxa have been described from Spain and Morocco. Several varieties of subsp. subcaulescens may be recognised in Anatolia; where this eastern subspecies has its centre of diversity.
