Characteristics

Shrubs semievergreen, 2–5 m tall, much branched. Branchlets robust, dark grayish brown, terete, initially densely yellow pubescent, glabrous when old. Petiole thick, 4–6 mm, initially yellow pubescent, later glabrous; stipules mostly caducous, lanceolate, 4–5 mm, puberulous; leaf blade elliptic or narrowly elliptic to ovate, (1.5–)3–6 × 1.5–2.5 cm, lateral veins 5–8 pairs, abaxially initially slightly pubescent or tomentose, glabrescent, with bloom, adaxially glabrous, base broadly cuneate to rounded, apex acute or obtuse. Compound corymbs to 3–5 cm, densely 6–12-or 40–50-flowered or more; rachis and pedicels pubescent or tomentose; bracts caducous, subulate, 2–3 mm, slightly pubescent. Pedicel 2–4 mm. Flowers 7–8 mm in diam. Hypanthium campanulate, abaxially pilose. Sepals triangular, 1–2 × 1.5–2.5 mm, apex acute. Petals spreading, white, suborbicular or broadly obovate, 3–4 mm, adaxially puberulous near base, base shortly clawed, apex obtuse, rarely emarginate. Stamens 20, ca. as long as petals. Ovary puberulous apically; styles 2, free, nearly equalling or lower than stamens. Fruit reddish yellow, ovoid to obovoid, 6–7 mm in diam., glabrous when mature, pyrenes usually 2. Fl. Jun–Jul, fr. Sep–Oct.

Lvs mostly distributed along young long shoots, often clustered on short shoots; petiole 2-7 mm long; blade elliptic, broad-elliptic or occasionally obovate, (20)-30-70 × (12)-15-37 mm, subcoriaceous, obtuse to rounded with a short mucro, cuneate at base, ± dull and glabrous with scarcely impressed veins above, pale buff to white-tomentose below when young but becoming glabrate and pale green or glaucescent; margins flat; stipules narrowly linear-lanceolate or linear-subulate, ± floccose at first, usually becoming glabrous or glabrate. Fls (5)-15-60, in flat corymbs distributed along upper part of branches; peduncles < diam. of corymbs, purplish, buff-tomentose, sometimes becoming glabrate. Sepals 1-1.8 mm long, triangular, pale tomentose, acute to short-acuminate. Petals ± patent, 2-3 mm diam., orbicular, white. Fr. subglobose to broadly turbinate, 4-7-(8) mm diam., scarlet or orange-red, glossy.
