basal: 0–2, unlobed or palmately 3–11-lobed;

petiole 5–27 cm, glabrous or puberulent;

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;

petiole 0.2–8.8 cm;

blade reniform to reniform-cordate, ± ovate, deltate, or rhombic, 1.5–5.5 × 1.4–10 cm, base cordate, subcordate, truncate, or attenuate, margins entire, crenate-serrate, or dentate, or coarsely lacerate to deeply serrate, often entire distally, ciliate or rarely eciliate, apex acute to obtuse, often long-tapered, mucronulate.

basal and cauline;

basal: 1–6;

stipules deltate, margins laciniate, apex usually long-acuminate;

petiole 3.7–10 cm, puberulent;

blade ovate, deltate, or subreniform, 1–6 × 1.2–4 cm, base usually cordate to subcordate, margins crenate, usually ciliate, apex acute, mucronulate, surfaces usually sparsely puberulent, glabrous early;

cauline similar to basal except: stipules lanceolate, margins ±fimbriate, sometimes stipitate-glandular, sometimes entire, erose, or ± laciniate;

petiole 0.4–9 cm;

blade ovate to deltate, 1.6–4.4 × 1.1–3.6 cm, base subcordate to truncate, margins crenate to ± serrate, ciliate, apex acute to obtuse.

2–13 cm, glabrous or pubescent.

1–10 cm, puberulent.

sepals lanceolate, margins ciliate or eciliate, auricles 0.1–1 mm;
