Shrubs 1 – 2 m tall, thorns 1 – 1.2 cm long or absent; branchlets initially pubescent and then glabrous, older branches gray-brown, sparsely lenticellate, glabrous. Stipules herbaceous, falcate, margin glandular-serrate. Leaves simple, deciduous; petioles 1.5 – 4 cm long, narrowly winged, glabrous; blades 4 – 8 cm long, 2 – 4 cm wide, obovate or long-elliptic; base cuneate, apex acuminate; usually 3 - lobed, rarely 5 - lobed or unlobed; margins irregularly double-serrate above the middle part; venation craspedodromous; glabrous adaxially, except for the loosely hairy midrib, pinnate veins slightly impressed above, prominent below, veins entering the tip of the serrations. Inflorescences corymb, 7 – 18 flowered, 4 cm long, 8 cm wide; pedicels and peduncles white-pubescent; bracts linear-lanceolate 2 – 3 mm long, margin glandular-serrate, caducous; hypanthium externally white-pubescent; small flower 2 cm in diameter; petals suborbicular, white, about 5 mm long, very shortly clawed; sepals triangular, apex caudate-acuminate, 4 – 6 mm long, nearly as long as the calyx tube, white-pubescent adaxially; stamens 20; styles 5, base white-villous.
