Shrubs erect, to 2 m tall. Stems fasciculate, robust; branchlets tomentose; prickles dense, yellowish, terete, straight, greatly variable in size and intermixed, to 5 mm, fine, evenly tapering to base, lower parts tomentose, intermixed with glandular bristles. Leaves including petiole 5–13 cm, thick; stipules mostly adnate to petiole, free parts ovate, abaxially tomentose, margin glandular-pubescent, apex acute; rachis and petiole tomentose, sometimes with a few, short prickles; leaflets 5–7(–9), elliptic or elliptic-obovate, 1.5–4.5 × 1–2.5 cm, abaxially tomentose, reticulate, adaxially glabrous, shiny, rugose due to concave veins, base rounded or broadly cuneate, margin acutely serrate, apex acute or rounded-obtuse. Flower solitary, or several and fasciculate, axillary, 4–5.5 cm in diam.; pedicel 5–25 mm, tomentose and glandular-pubescent; bracts ovate, abaxially tomentose, margin glandular-pubescent, apex acuminate.
