Russia Flora: Plant, up to 40 (50) cm tall. Root 1-2 cm long, 4-6 mm thick, vertical or more or less obliquely ascending. Stems solitary, with short semi-appressed hairs, becoming somewhat rigid in fruit, greenish-brown. Rosette leaves (1)2-3(4) at beginning of flowering, with petioles more than 1 mm thick, pubescent and colored similar to stem; blade 3-4(5) cm long and 6-7 cm wide, broadly cordate, mostly fully developed by flowering time, noticeably pubescent, once or twice ternately dissected; primary segments rhomboid, divided or dissected, in upper part incised-dentate, margins with short ciliate hairs. Cauline leaves usually fully developed, with petioles 1-2 cm long and blades similar to rosette leaves. Peduncles slightly elongating in fruit but usually shorter than lower part of stem. Flowers solitary, (3.5)4.5-6(7) cm in diameter. Perianth segments 5, up to 3(3.5) cm wide, elliptical or obovate, milk-white, densely appressed-hairy outside. Nutlets about 4 mm long, mostly very densely and long woolly-hairy, with stalk about 2 mm long at base; style short, horizontally deflected from base, slightly geniculate above, completely hidden by a crown of short and somewhat rigid hairs. 2n = 16 (Starodubtsev, 1983).
