Malus baccata (Linnaeus) Borkhausen subsp. himalaica (Maximowicz) Likhonos; M. baccata var. himalaica (Maximowicz) C. K. Schneider; Pyrus baccata Linnaeus var. himalaica Maximowicz.
Trees 8–10 m tall, pendulous. Branchlets dark brown, terete, villous when young, glabrescent; buds reddish brown, ovoid, subglabrous or scales puberulous at margin. Stipules caducous, lanceolate, 5–6 mm, membranous, subglabrous, margin slightly glandular denticulate, apex acuminate; petiole 2–4 cm, villous; leaf blade elliptic, ovate-elliptic, or oblong-ovate, 6–12 × 3.5–7 cm, abaxially puberulous along midvein and lateral veins, adaxially sparsely pubescent along midvein, base rounded or broadly cuneate, margin irregularly adpressed serrulate, apex acuminate. Corymbs umbel-like, 4–6 cm in diam., 4–8-flowered; bracts caducous, lanceolate, membranous, margin sparsely glandular serrate, apex acuminate. Pedicel 2–4 cm, pubescent. Flowers 2.5–3 cm in diam. Hypanthium campanulate, densely villous. Sepals triangular-lanceolate, 5–7 mm, slightly longer than or ca. as long as hypanthium, abaxially sparsely pubescent or subglabrous, adaxially densely pubescent, margin entire, apex acute or acuminate. Petals white, obovate, 1.2–1.5 cm, base shortly clawed, apex rounded. Stamens 25, unequal, shorter than petals. Ovary 4- or 5-loculed, with 2 ovules per locule; styles 4 or 5, slightly longer than stamens, villous basally. Pome red, ovoid or subglobose, 1–1.5 cm in diam. with a small scar at apex; sepals caducous; fruiting pedicel 2–4 cm, puberulous. Fl. May–Jun, fr. Sep. 2n = 34*, 51*.
Mixed forests in valleys; 2400--3800 m. SW Sichuan, SE Xizang, NW Yunnan [Bhutan].
