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.

basal, 2–5, prostrate to ascending, often overlapping basally;

stipules linear-lanceolate, margins entire, apex acute;

petiole 2–8 cm, pubescent;

blade unlobed, orbiculate, reniform, or ovate, 2–12 × 1.5–9 cm, base cordate, margins crenate to serrate, sometimes glandular, ciliate or eciliate, apex rounded to acute, surfaces usually pubescent throughout or concentrated proximally on both surfaces.

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;

sepals lanceolate to ovate, margins mostly eciliate, auricles 0.5–1 mm;

petals pale to bluish violet on both surfaces, lower 3 white basally and darker violet-veined, lateral 2 and often upper 2 and lowest bearded, lowest 15–18 mm, spur white, gibbous to usually elongated, 3–5 mm;
