Leaves simple; petiole 1–2 cm, gray tomentose at first, gradually glabrescent, with sparse, minute prickles; stipules early caducous, free, oblong or elliptic, villous, stipitate glandular, margin entire or apically laciniate; blade broadly ovate, 6–11 × 4–8 cm; veins 5–7 pairs, prominent abaxially, somewhat impressed adaxially, not leathery, abaxially densely gray or yellowish gray tomentose, adaxially dark brown, glabrous except soft hairy along veins, base cordate, margin lobed, unevenly sharply serrate, apex acuminate. Inflorescences terminal, racemes, 6–9 cm, loosely few flowered; rachis and pedicels tomentose-villous, with stipitate glands 2–4 mm and sparse, needle-like prickles; bracts caducous, oblong or elliptic, 5–8 mm, membranous, villous, with sparse, intermixed stipitate glandular hairs, margin entire or apically lobed. Pedicel 1.5–2.5 cm. Flowers 1–1.5 cm in diam. Calyx abaxially densely tomentose-villous, with purplish brown long stalked glands and needle-like prickles; sepals erect, rarely reflexed in fruit, broadly ovate, 1–1.2 cm × 4–6 mm, margin entire, apex caudate. Petals broadly elliptic, 8–11 × 5–7 mm, soft hairy, base shortly clawed, apex obtuse. Stamens many, shorter than petals; filaments short, broad, complanate; anthers slightly villous.
