Buds reddish brown, ovoid, 1.6 mm, scale margins tomentose. Leaves conduplicate in bud; heteromorphic; stipules deciduous, linear-lanceolate, 2–4(–5) mm, apex acuminate; vigorous shoot leaves: petiole (10–)15–25 mm, villous, sometimes tomentose; blade elliptic, oval, or ovate, sometimes triangular-ovate, (3.5–)4–6(–8) × (1.5–)3–4(–5) cm, base cuneate, sometimes rounded, margins sometimes slightly lobed, crenate, crenate-serrate, serrate, or entire, sometimes doubly serrate, apex rounded, broadly acute, sometimes apiculate, abaxial surface glabrous (villous only on veins), adaxial glabrous; flowering shoot leaves: petiole 3–10(–25) mm, villous, sometimes glabrous; blade elliptic or oblong, sometimes ovate, obovate, or lanceolate, (9–)15–50(–65) × (7–)10–20(–30) mm, base cuneate, sometimes rounded, margins unlobed, crenate, crenate-serrate, or entire, apex rounded (with point or acute), abaxial surface glabrous (veins villous), adaxial glabrous. Panicles corymblike; peduncles absent; bracteoles sometimes persistent, filiform, (1–)3–4(–6) mm. Pedicels (10–)20–30(–40) mm, glabrous, sometimes slightly villous. Flowers 20–30 mm diam.; hypanthium glabrous, rarely slightly villous; sepals triangular, (2–)3–4(–5) mm, equal to tube, apex acuminate, abaxial surface glabrous, adaxial hoary-tomentose; petals pink, sometimes fading white, oblong to narrowly obovate, (10–)12–16(–22) mm, claws (2–)3 mm, margins entire, sinuate, or fimbriate, apex rounded; stamens 20, (7–)9–12(–14) mm, anthers pink or rose before dehiscence; styles 5, connate basally, (6–)9–12(–15) mm, usually slightly longer than stamens, tomentose in proximal 1/3. Pomes green or yellow-green, subglobose, 10–20(–30) mm diam., cores not enclosed at apex; sepals persistent, erect; sclereids abundant surrounding core. Seeds dark brown. 2n = 34 (68).
