1–3, erect, leafless proximally, leafy distally, glabrous or puberulent, from subligneous rhizome.

1–3, prostrate, decumbent, or erect, glabrous or sparsely puberulent, from short, often vertical, deep-seated or usually shallow, subligneous rhizome.

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: 1–3, palmately compound, leaflets 3;

stipules lanceolate-ovate, margins laciniate with gland-tipped projections, apex acute to acuminate;

petiole 8.6–21 cm, glabrous or sparsely puberulent;

blade reniform or ovate to ± orbiculate, 2–7 × 2–11 cm, coriaceous, base tapered, each leaflet cleft or dissected into 3 ± obovate lobes, each lobe further divided into 2–3 oblanceolate, pandurate, spatulate, oblong, lanceolate, or elliptic, lobes 2–10 mm wide, margins entire, ciliate or eciliate, apex acute to obtuse, mucronulate, surfaces glabrous or sparsely puberulent;

cauline similar to basal except: stipules ovate to lanceolate, margin projections gland-tipped or eglandular, apex long-acuminate;
