Pedicel 3–5 cm, brown tomentose, soon glabrescent. Flowers 2–3 cm in diam. Hypanthium sparsely tomentose abaxially. Sepals persistent or caducous, triangular-ovate, ca. 3 mm, abaxially sparsely tomentose, adaxially tomentose, margin glandular denticulate, apex acuminate or acute. Petals white, broadly ovate, 1–1.2 cm, shortly clawed at base, apex rounded. Stamens 20, ca. 1/2 as long as petals. Ovary 3(or 4)-loculed, with 2 ovules per locule; styles 3(or 4), ca. as long as stamens, sparsely pubescent basally. Pome dark brown, subglobose or obovoid, 1.5–2.2 cm in diam., 3-or 4-loculed; with persistent sepals or sometimes a few caducous; fruiting pedicel 3–4 cm, subglabrous. Fl. Apr, fr. Jun–Aug. 2n = 34*.
