Shrubs or small trees, 3–8 m tall. Branchlets dark grayish brown or dark reddish brown, terete, lenticellate, puberulous when young, glabrous when old; buds narrowly ovoid, 0.9–1.4 cm, apex acute to shortly acuminate; scales several, dark reddish brown, glabrous or rust-brown pubescent along margin. Leaves pinnately compound, together with rachis 10–15 cm; petiole 1–3 cm; stipules caducous, ovate to lanceolate, 0.8–1.2 cm × 5–6 mm, margin entire or few toothed at apex; rachis shallowly sulcate, glabrous or puberulous, winged; leaflet blades 7–9(or 10) pairs, at intervals of 1–1.5 cm, oblong to oblong-lanceolate, 2.5–5 × 1–1.5 cm, lateral veins 10–20 pairs, both surfaces pilose or abaxially rust-brown pubescent along midvein, sometimes glabrescent, base obliquely rounded or broadly cuneate, margin minutely to coarsely serrate, apex acute, rarely obtuse. Compound corymbs terminal, rarely axillary, 4–6 × 3–5 cm, densely flowered; rachis and pedicels initially sparsely rust-brown pubescent, sometimes glabrescent or subglabrous; bracts caducous, linear to lanceolate, smaller than stipules. Pedicel 1–2 mm. Flowers 6–8 mm in diam. Hypanthium campanulate, abaxially glabrous or subglabrous. Sepals triangular, 1.5–2.5 mm, apex obtuse. Petals white, broadly ovate or elliptic-ovate, 3–5 × 2–3.5 mm, glabrous, base broadly clawed, apex obtuse. Stamens 20, ca. 1/2 as long as petals. Styles (4 or)5, ca. as long as or slightly longer than stamens, puberulous basally. Fruit pinkish white to crimson, ovoid, 6–8 mm in diam.; sepals persistent. Fl. May–Jun, fr. Aug–Sep. 2n = 34*.
Can be grown by cuttings, graftings or seedlings. Seeds needs stratification.
