Russia Flora: Plant, up to 35 (40) cm tall, with rooting, stolon-like underground shoots. Root crown short, more or less vertical, slightly thickened, with membranous scales toward apex, in whose axils sessile dormant buds firmly attached to root crown form, sometimes these are absent, and then root crown very short, not fully developed, originating from still living stolon-like underground shoot. Stems solitary, erect, sparsely hairy, sometimes almost glabrous, at base with 1-2(3) basal leaves with long petioles, pubescent similar to stem. Leaf blades 3-5 cm long, 6-9 cm wide, reniform, with deeply cordate base, dissected into 3 almost sessile primary segments: 2 lateral segments somewhat obliquely broadly ovate, sometimes fan-shaped, varying from bilobed to bidissected, and middle segment rhomboid, shallowly three-lobed, rarely three-parted; all 3 primary segments incised-dentate along upper margin, finely hairy, with shallowly overlapping or sometimes only touching, very rarely with diverging lateral sides. Cauline leaves 3, sessile, noticeably smaller than rosette leaves, mostly rhomboid, from almost entire to three-parted (one leaf usually underdeveloped). Peduncles not drooping. Flowers solitary, rarely 2(3), (2)2.5-3(3.5) cm in diameter. Perianth segments 5(6), 8-10 mm wide, obovate, white. Ovary short appressed-hairy, with large, sessile, bilobed stigma. Nutlets about 5-6 mm long, slightly laterally compressed, mostly short appressed-hairy, with thickish, greenish pericarp separated from seed. 2n = 14 and 21 (Starodubtsev, 1991).
