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, 5 or 6, prostrate to ascending;

stipules linearlanceolate, margins entire, apex acute;

petiole 1.5–7 cm, usually glabrous;

earliest leaf blades ± ovate, sometimes 3-lobed, mid-season blades 7–9-lobed, 1–9 × 1–10 cm, base broadly cordate to cordate, middle lobes narrowly elliptic, lanceolate, spatulate, or obovate, (rarely linear), lateral lobes lanceolate or spatulate to falcate, margins usually entire, sometimes serrate, sometimes with narrowly deltate or falcate appendages or teeth, ciliate or eciliate, apex acute to mucronulate, surfaces usually glabrous.

2–13 cm, glabrous or pubescent.

2–20 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 lanceolate to ovate, margins ciliate or eciliate, auricles 0.5–1 mm;

petals light to dark blue-violet on both surfaces, lower 3 and sometimes upper 2 white basally, lower 3 darker violet-veined, lateral 2 densely bearded, spur sometimes bearded, lowest 15–25 mm, spur usually lilac, sometimes whitish, gibbous, 2–3 mm;

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

ellipsoid-ovoid, 6–16 mm, glabrous.

ellipsoid, 11–14 mm, glabrous.

light brown, blotched or streaked with brown, shiny, 2.1–2.7 mm.

beige, mottled to bronze, 2–3 mm.
