Trees, sometimes shrubs, 10–50 (–100) dm. Stems 5–25 cm diam.; bark reddish-brown to gray, longitudinally fissured with platelike scales; young branches reddish-brown, sparsely puberulent, becoming gray or grayish brown, glabrescent; flowering shoots developing as short spurs or spiny thorns, (5–) 10–40 (–60) mm. 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).
