Leaves coarse, terminal leaflets usually 3-lobed, or at least 2-lobed, even if weakly or unevenly; petiole, rachis, and petiolules usually stipitate-glandular. Leaflets petiolulate; blade ovate, 8-15 × 4-15 cm, base usually cordate, rarely cuneate, margins sharply serrate to crenate, apex acuminate. Flowers: sepals persistent, triangular, 0.7-1.5 mm; petals 5 or absent in pistillate flowers, erect, spatulate to subulate, 1.5-4 mm. Capsules partly connate, or separating as 2 follicles, 3.5-4 mm. Seeds 5-10, linear, 1.5-2 mm. 2n = 28.
