blade sometimes glaucous, deltate to reniform, 3.5–8.5 × 4.5–13.5 cm, base cordate, truncate, or attenuate, margins on unlobed leaves coarsely dentate-serrate, margins on lobed leaves usually entire, sometimes few-toothed, ciliate (sometimes only proximal 1/2) or eciliate, apex acute to obtuse, mucronulate, surfaces glabrous or puberulent;

cauline similar to basal except: distal on naked stems, unlobed and divided leaves can occur on same plant, if divided, palmately 3–12-lobed;

stipules sometimes large and ± leaflike, margins entire, lacerate, or laciniate, sometimes with gland-tipped projections, apex acute to acuminate;
