Trees to 5–8 m tall. Branchlets purplish red when young, purplish brown when old, terete, white tomentose when young, glabrous when old, sparsely pale lenticellate; buds narrowly ovoid, apex obtuse; scales tomentose at margin. Stipules caducous, linear-lanceolate, 1–2 mm, membranous, adaxially sparsely tomentose, margin sparsely glandular denticulate, apex acuminate; petiole 2–6 cm, sparsely pubescent or subglabrous; leaf blade elliptic-ovate or narrowly ovate, 6–10 × 3.5–5 cm, sparsely tomentose when young, soon glabrescent, base broadly cuneate, margin serrate, apex long acuminate. Raceme umbel-like, 5–8-flowered; peduncle tomentose when young, soon glabrescent; bracts caducous, linear-lanceolate, 8–11 mm, membranous, adaxially villous, margin entire, apex acuminate. Pedicel 2–2.5 cm, subglabrous. Flowers ca. 3 cm in diam. Hypanthium campanulate, abaxially white tomentose. Sepals triangular-lanceolate, 2–3 mm, adaxially tomentose, margin entire, apex acuminate. Petals white, ovate, 1–1.5 cm, base shortly clawed, apex rounded. Stamens 20, ca. 1/2 as long as petals. Ovary (2- or)3- or 4-loculed, with 2 ovules per locule; styles (2 or)3 or 4, nearly as long as stamens, glabrous basally. Pome brown with pale dots, globose or ovoid, 2–2.5 cm in diam., 3- or 4-loculed; sepals caducous; fruiting pedicel 2–4 cm, glabrous. Fl. Apr, fr. Aug–Sep. 2n = 34*.
