Flora of North America species comparison

1–5, prostrate, spreading, finely puberulent, from current and/or previous year’s growth, on usually vertical, fleshy rhizome, rooting and forming rosettes at or near tip; rooted rosettes often develop into an erect, fleshy caudex from which new stems are produced.

1–4, prostrate, decumbent, or erect, leafy proximally and distally, glabrate or sparsely puberulent, on caudex from subligneous rhizome.

basal and cauline;

basal: 3–6;

stipules lanceolate, margins laciniate, projections often long-filamentous, apex long-acuminate;

petiole 2.3–7.3 cm, glabrous or pubescent;

blade often purple-spotted abaxially and/or adaxially, ovate to reniform, 1.2–5 × 1.6–3.6 cm, base deeply to broadly cordate, margins crenulate to serrate, ciliate or eciliate, apex rounded to obtuse, surfaces glabrous or pubescent;

cauline similar to basal except: stipules ovate to lanceolate, margins laciniate;

petiole 1–3.5 cm;

blade 1.3–2.9 × 1.4–3.2 cm.

basal and cauline;

basal: 1–3;

stipules adnate to petiole, forming 2 linear-lanceolate wings, margins entire or laciniate with glandular hairs, apex of each wing free, acute, sometimes divided into several filiform processes;

petiole 2–8(–12) cm, glabrate or sparsely puberulent;

blade usually broadly ovate, sometimes ± orbiculate, 1–4.5 × 0.7–3.4 cm, base usually attenuate, rarely truncate or subcordate, margins ± coarsely crenate-serrate, ciliate, apex obtuse, surfaces glabrate or sparsely puberulent;

cauline similar to basal except: stipules lanceolate or linear-lanceolate to linear, margins ± entire or lacerate to laciniate with sparse gland-tipped projections, apex acute to acuminate, often divided into 2–4 filiform processes;

petiole 3–8.7 cm;

blade ovate to oblong-ovate or oblong-lanceolate, 0.7–1.6 × 2.6–3.7 cm, margins shallowly serrate, irregularly crenate, or ± entire, apex acute to obtuse.

5–9.6 cm, glabrous or pubescent.

4–10 cm, glabrate or sparsely puberulent.

style head bearded; cleistogamous flowers axillary.

sepals lanceolate, margins ciliate or eciliate, auricles 1–1.5 mm;

petals deep lemon-yellow adaxially, upper 2 and sometimes lateral 2 reddish brown to brownish purple abaxially, lower 3 and sometimes upper 2 dark brown-veined, lateral 2 sparsely bearded, lowest 10–13 mm, spur yellow, gibbous, 0.5–1.5 mm;
