Small shrub to small tree, up to 8 m. Twigs glabrous to minutely patently hairy. Axillary buds ovate, 1.8—3.5(—5?) mm long, very thick (mostly not especially basally), obtuse, light brown and often more or less reddish, often irregular because of cork-forming. Petiole 4-9 mm, the young ones nearly smooth, not transversely wrinkled, glabrous to minutely densely patently hairy all round, the older ones soon becoming transversely cracked, more or less corky; glands often present, mostly rather distinct. Leaf-blade (5.5-)7.5-30 by 2.4-11.5 cm; base rounded-cordate, rarely rounded, obtuse, or cuneate-rounded, apex acutish, rarely rounded; above rarely bullate between midrib and secondary nerves, greyish green, midrib slightly sunken to flat, rarely indistinctly prominent; beneath glaucous-papillose, secondary nerves (6 or) 7-12 (or 13) pairs, forming mostly an indistinct intramarginal nerve in apical half; glands numerous, scattered, c. 0.1-0.2 mm diam. Inflorescences at end of young twigs but also axillary, not rarely on old nodes, unbranched, shorter than the leaves, many-flowered; axes stiff, minutely patently hairy; in basal part flowers with up to 3 together. Pedicel 2.5-3.5(—4.5) mm, finely grooved, very densely minutely patently hairy. Sepals often with rather distinct glands; outer sepals 2.1-5 by 2.7-4.2 mm; inner sepals 3.2-6 by 3.2-4.9 mm. Petals pink or whitish, when dry red or brownish orange, slightly hairy apically and basally inside, further glabrous, the longest one 13-18 mm. Stamens: anthers (1.3—)1.7—2.5(—3.6) mm long, faintly hairy at base, sparsely ciliate along slits. Ovary up to 2 mm stipitate, patently light brownish pubescent; style glabrous in apical part; ovules 12-16. Fruit globular, up to 2 cm diam.; pericarp thin.
