Flora of North America species comparison

1–3(4), usually erect to ascending, glabrous or puberulent, from fleshy or subligneous rhizome.

basal and cauline;

basal: 1–5;

stipules ± oblong, ovate, or lanceolate, margins entire, sometimes glandular, apex acuminate to cuspidate;

petiole 1.1–23 cm, glabrous or puberulent;

blade ovate to broadly ovate or ovate-reniform, 0.7–12.4 × 0.9–11.1(–12.3) cm, base cordate, subcordate, or truncate, margins crenate, crenulate, or serrulate, ciliate (sometimes only on proximal 1/2) or eciliate, apex acute to acuminate, surfaces glabrous or puberulent (often only on veins);

cauline similar to basal except: stipules also deltate, margins also erose or laciniate, apex acute, long-acuminate to cuspidate, or ± truncate, occasionally 2- or 3-fid;

petiole 0.1–6.9(–15.2) cm;

blade ovate to deltate, 1.2–7.7 × 0.8–7.8 cm, base cordate to truncate, margins crenate or crenulate to ± serrulate.

basal, 5–9, ascending to erect, 5–9-lobed;

stipules linear-lanceolate, margins entire, apex obtuse;

petiole 3–16 cm, usually glabrous;

mid-season blades incised or lobed throughout, earliest blades lobed (plants homophyllous), similar to mid-season blades, middle and lateral blade lobes differ in width and/or shape, middle lobes lanceolate or spatulate to narrowly obovate, lateral lobes lanceolate or spatulate to falcate (each sometimes with deltate to falcate appendages or teeth along margins), 1–7 × 2–8 cm, base truncate to cordate, margins entire, ciliate, apex acute to obtuse, surfaces usually glabrous, rarely with a few strigose, hairs concentrated on veins.

1–6.1 cm, glabrate to puberulent, sometimes glabrous below bracteoles.

5–18 cm, usually glabrous.

sepals lanceolate, margins usually eciliate, auricles 0.5–1.3 mm;

petals white adaxially, upper 2 and lower 3 tinged soft reddish violet abaxially, rarely white on both surfaces, all petals usually with yellow patch basally, lower 3 usually purple-veined, lateral 2 bearded, lowest 5.5–20 mm, spur white, gibbous, 1–2 mm;

style head bearded; cleistogamous flowers axillary or absent.

sepals lanceolate to ovate, margins ciliate or eciliate, auricles 2–3 mm;

petals light to soft reddish violet on both surfaces, lower 3 white basally, dark violet-veined, lateral 2 bearded, lowest 10–25 mm, sometimes bearded, spur same color as petals, gibbous, 2–3 mm;

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

ovoid to ellipsoid, 2.5–10 mm, sometimes muriculate, glabrous or puberulent.

ellipsoid, 10–15 mm, glabrous.
