Shrubs lianoid, to 2 m tall, stoloniferous. Branchlets brown to purplish brown, tomentose-villous, with curved minute prickles, sometimes with glandular hairs. Leaves simple; petiole 3–7 cm, tomentose-villous, with minute prickles; stipules broadly flabellate, 1–1.5(–2) cm, membranous, pectinately or palmately parted nearly to base; lobes lanceolate or linear, villous; blade orbicular to broadly ovate, 7–14 cm in diam., 5-veined, veins distinctly raised abaxially, slightly impressed adaxially, papery, abaxially densely gray tomentose and villous, with minute needle-like prickles along veins, adaxially prominently rugose, sparsely villous, base cordate, margin 5–7-lobed; lobes irregularly coarsely serrate to doubly serrate, apex obtuse or acute. Inflorescences terminal and axillary, short subracemes, 3–5 cm, 1- or few flowered, or flowers several in clusters in leaf axils; rachis and pedicels gray or yellowish tomentose-villous; bracts narrower than stipules, 1–1.5 cm, villous, deeply divided similar to stipules; lobes linear to lanceolate. Pedicel 7–10(–15) mm. Flowers ca. 1.5 cm in diam. Calyx gray or yellowish tomentose and villous; sepals narrowly ovate or ovate-lanceolate, unequal in length, longer sepals to 1.5 cm, shorter sepals 6–8 mm, apex acuminate; outer sepals pinnatipartite, lobes lanceolate, inner sepals entire, occasionally with minute glandular hairs.
