Basal leaf blades usually 5-6 cm long, 5-7 cm wide, from reniform to almost circular, dissected into 3(4-5) mostly similar primary segments; these narrowly and deeply twice ternately dissected, with linear or linear-lanceolate, more or less falcate curved, sometimes almost straight, usually somewhat acute, rarely blunt terminal lobes; lateral sides of segments overlapping each other or sometimes only touching. Flowers 1-4, arranged in umbels. Peduncles already at beginning of flowering at least (1.5)2-2.5 times longer than cauline leaves, elongating even more in fruit. Flowers 1.2-1.7(2) cm in diameter. Perianth segments 5-6, about 5-9 mm wide, oblong-obovate, white. Nutlets up to 7 mm long, black or almost black.
