Leaves usually compound and 3-foliolate, rarely simple and divided; petiole 2–3.5 cm, pilose, with minute needle-like prickles; lateral leaflets subsessile, petiolule of terminal leaflet 1–2 cm; stipules free, on flowering branches ovate or elliptic, 5–8 × 3–5 mm, on creeping branches narrower, lanceolate or linear-oblong, pubescent, margin entire; blade of leaflets ovate-rhombic or oblong-rhombic, terminal leaflet 5–7 cm, slightly longer than lateral leaflets, both surfaces pubescent, more densely so along veins abaxially, base subcuneate or obliquely subcuneate, margin often coarsely doubly serrate, rarely incised-serrate, lateral leaflets sometimes 2-lobed, apex acute. Inflorescences corymbs or flowers several in clusters; peduncles unequal in length, shorter ones ca. 5 mm, longer ones to 3 cm; bracts ovate or elliptic, rarely linear-oblong, pubescent, margin entire. Pedicel 6–10 mm, pilose, with minute needle-like prickles, often with stalked glands. Flowers less then 1 cm in diam. Calyx turbinate, sometimes pelviform in fruit, abaxially pubescent; sepals ovate-lanceolate, 5–7 × 1.5–2.5 mm, apex acuminate. Petals white, spatulate or oblong, 6–9 × 3–5 mm, glabrous, base clawed, erect. Stamens many, much shorter than petals; filaments erect, base inflated, apex subulate, incurved. Pistils 5 or 6, nearly equaling stamens. Aggregate fruit red, globose, 1–1.5 cm in diam., glabrous, with larger drupelets; pyrenes oblong, alveolate-pitted. Fl. Jun–Jul, fr. Jul–Aug. 2n = 28.
