The leaves are broadly ovate, dull, deep green above, slightly lighter below, sparsely pubescent, later glabrous. On flowering shoots, the lower leaves are obovate to elongated, with a wedge-shaped, often narrow, base, from almost entire or coarsely toothed at the apex to three-lobed; the upper ones are up to 6 cm long, up to 6-6.5 cm wide, in outline from broadly ovate to rounded and even elongated in width, with a broadly wedge-shaped or almost cut off or rounded base, five or seven-parted; the lobes are usually wide, less often narrow, the lower ones are usually much larger than the upper ones, all sharp, the upper ones directed upward. Leaves on sterile shoots are 6-6.5 cm long and wide, ovate, seven-parted, almost dissected at the base, often with narrower lobes, with doubly coarsely serrated and incised edges.
Inflorescences are almost equal in length to the leaves, 5-15-flowered, glabrous; pedicels 3-18 mm long; sepals broadly ovate-triangular, suddenly narrowed at the apex into a pointed point or gradually retracted. Corolla up to 2 cm in diameter; stamens 17-20; columns 2, less often 1 or 3.
