Leaves mostly trifoliolate, but sometimes pinnate with the basal divisions trifoliolate; leaflets thin, broadly ovate to ovate-lanceolate, 1 to 3 in. long, heart-shaped to tapering at the base, deeply toothed, often three-lobed, nearly glabrous, except for hairs on the nerves beneath. Flowers dull white, 5⁄8 in. across, in axillary panicles 2 to 6 in. long, produced in September and October; sepals very downy outside, spreading; stamens glabrous. Seed-vessels with silky styles.
