petiole (1–)2.7–9.5 cm, glabrous or hairy, with scattered, yellow, sessile, round glands;

blade reniform to orbiculate, 3-lobed, 2 proximal segments less deeply and very unequally lobed (rarely equally 5-lobed), cleft usually less than 1/2 to midrib, 2–12(–13.3) cm, base deeply cordate, surfaces with yellow, sessile, round glands abaxially, otherwise glabrous or copiously hairy abaxially, sparsely hairy adaxially, lobes broadly deltate, margins coarsely bicrenate-dentate, apex acute.

pendent, solitary flowers or 2-flowered racemes, 3–4 cm, axis pilose, stipitate-glandular.

ascending to spreading, 20–50-flowered racemes, 3–17 cm, axis thinly villous, flowers evenly spaced.
