Shrubs or small trees, 3–6 m tall. Branchlets purplish brown or dark brown when old, terete, puberulous when young, glabrous when old; buds purplish brown, ovoid, pubescent, apex acute. Stipules lanceolate, 4–6 mm, sparsely pubescent, margin entire, apex acuminate; petiole 1–3 cm, puberulous; leaf blade variable in shape, ovate or narrowly elliptic, 3–8 × ca. 1.5 cm, abaxially densely pubescent along midvein and lateral veins, adaxially sparsely pubescent, base broadly cuneate or subcordate, margin obtusely serrate, often 3–5 parted, sometimes undivided, apex acute. Corymb umbel-like, 3–5 cm in diam., 3–5-flowered; bracts caducous, linear, membranous, adaxially pubescent when young, margin sparsely glandular serrate, apex acuminate. Pedicel 1.8–2.5 cm, sparsely villous. Flowers 2–2.5 cm in diam. Hypanthium tomentose abaxially. Sepals triangular-lanceolate or narrowly triangular, 3–4 mm, nearly as long as hypanthium, both surfaces white tomentose, margin entire, apex acuminate. Petals white, ovate or elliptic-obovate, 8–11 mm, adaxially sparsely pubescent or glabrous, base shortly clawed, apex rounded. Stamens ca. 20; filaments unequal, shorter than petals. Styles 3(or 4 or 5), not exceeding stamens, glabrous. Pome yellow, tinged red, obovoid or narrowly ellipsoid, 1–1.3 cm; sepals caducous; fruiting pedicel 3–4 cm, glabrous, Fl. Apr–May, fr. Sep. 2n = 34*, 51*, 68*.
