Characteristics

Trees, sometimes shrubs, 30–50(–80) dm. Stems to 35 cm diam.; bark gray, longitudinally fissured at maturity; young branches green and sparsely puberulent, becoming dark purplish brown and glabrous; flowering shoots developing into spurs, 5–10(–15) mm. Buds purplish brown, ovoid, 4–5 mm, scale margins glabrous or ciliate. Leaves convolute in bud; isomorphic; stipules deciduous, lanceolate, 4–6 mm, apex acuminate; petiole 5–25 mm, glabrescent; blade ovate, elliptic, or narrowly elliptic, 3.5–8 × 2.5–4.5 cm, base cuneate or subrounded, margins unlobed, obtusely serrulate, apex long-acuminate, surfaces glabrous or sometimes puberulous along midveins. Panicles umbel-like; peduncles absent; bracteoles absent. Pedicels 20–40 mm, sparsely puberulent. Flowers ?some trees reportedly andromonoecious, inflorescences with 1 or more staminate flowers or flowers all bisexual?, 30–35 mm diam.; hypanthium glabrous; sepals triangular-ovate, 3–5 mm, equal to or shorter than tube, apex obtuse, abaxial surface glabrous, adaxial tomentose; petals ?usually more than 5?, pink, obovate, 15 mm, claws 1 mm, margins entire, apex rounded; stamens 20–25, 4–6(–8) mm, anthers white before dehiscence; styles 4 or 5, basally connate, length unknown, slightly longer than stamens, long-tomentose basally. Pomes dark red or purple, pyriform or obovoid, 6–8 mm diam., cores enclosed at apex; sepals deciduous; sclereids sparse to moderate surrounding core. Seeds brown. 2n = 34.
More
Trees to 5 m tall. Branchlets purple or purplish brown, terete, slender, puberulous when young, glabrescent; buds purplish brown, ovoid, glabrous or scales ciliate at margin. Stipules caducous, lanceolate, small, 4–6 mm, membranous, puberulous adaxially, margin glandular denticulate when young, apex acuminate; petiole 0.5–2.5 cm, sparsely pubescent when young, glabrescent; leaf blade dark green and often tinged purple adaxially, ovate, elliptic, or narrowly elliptic, 3.5–8 × 2.5–4.5 cm, glabrous except sometimes puberulous along midvein, base cuneate or subrounded, margin obtusely serrulate, apex long acuminate. Corymb 4–6 cm in diam., 4–6-flowered; bracts caducous, lanceolate, membranous, margin entire, apex acuminate. Pedicel pendulous, purple, 2–4 cm, slender, sparsely pubescent. Flowers 3–3.5 cm diam. Hypanthium glabrous abaxially. Sepals triangular-ovate, 3–5 mm, ca. as long as or slightly shorter than hypanthium, abaxially glabrous, adaxially tomentose, margin entire, apex obtuse. Petals often more than 5, pink, obovate, ca. 1.5 cm, base shortly clawed, apex rounded. Stamens 20–25, unequal, ca. 1/2 as long as petals. Ovary 4-or 5-loculed, with 2 ovules per locule; styles 4 or 5, slightly longer than stamens, long tomentose basally. Pome purplish, pyriform or obovoid, 6–8 mm in diam.; fruiting pedicel 2–4 cm, subglabrous; sepals caducous; with a small scar at apex. Fl. Mar–Apr, fr. Sep–Oct. 2n = 34*, 51*.
