Flora of North America species comparison

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

basal and cauline;

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

stipules ovate to lanceolate, margins ± entire or serrate, apex acute;

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, 4–7, ascending to erect;

stipules lanceolate, margins entire or fimbriate, apex acute;

petiole 2–25 cm, usually glabrous;

blade usually grayish green or purplish green abaxially, unlobed, ovate, reniform, or broadly reniform to orbiculate, 1–7 × 1–7 cm, somewhat fleshy, base broadly cordate or reniform to ± truncate, margins crenate to serrate, ciliate or eciliate, apex acute to obtuse or rounded, surfaces usually glabrous, rarely sparsely pubescent.

2–13 cm, glabrous or pubescent.

3–25 cm, usually glabrous.

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

petals deep lemon-yellow adaxially, usually upper 2 and sometimes lateral 2 brownish purple abaxially, lower 3 and sometimes upper 2 brownish purple-veined basally, lateral 2 bearded, lowest 8–19 mm, spur yellow to greenish, gibbous, 0.5–2 mm;

style head bearded; cleistogamous flowers axillary.

sepals ovate, margins usually eciliate, auricles 1–2 mm;

petals deep bluish violet on both surfaces, lower 3 white basally and darker violet-veined, lateral 2 bearded, upper 2 sometimes sparsely bearded, lowest densely bearded or beardless, 10–28 mm, spur same color as petals, gibbous, 2–3 mm;

style head beardless; cleistogamous flowers on erect to ascending peduncles.
