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, 2–6, ascending to erect;

stipules ovate to linear-lanceolate, margins entire or glandular-toothed, apex acute;

petiole 1–10 cm, strigose;

blade unlobed, reniform to ovate, 1–6.5 × 1–5.5 cm, base broadly or shallowly cordate, margins ± entire or shallowly crenate, eciliate, apex rounded to acute, surfaces usually glabrous, abaxial surfaces sometimes puberulent on proximal 1/2.

2–13 cm, glabrous or pubescent.

2.5–11(–21) cm, usually glabrous, sometimes villous.

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 lanceolate to ovate, margins eciliate, auricles 0.5–2 mm;

petals white on both surfaces, lower 3 purple-veined, lateral 2 bearded, rarely beardless, lowest 6–12 mm, spur white, gibbous, 1–2.5 mm;

style head beardless; cleistogamous flowers on ascending peduncles.

ellipsoid-ovoid, 6–16 mm, glabrous.
