1–5, prostrate, spreading, glabrous or sparsely 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.

evergreen, basal and cauline;

basal: 1–6(–10);

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

petiole 2–16 cm, glabrous;

blade often purple-spotted abaxially and/or adaxially, orbiculate to ovate, 1–4.5 × 2–3.9 cm, base cordate to truncate, margins crenate, eciliate, apex blunt to obtuse, mucronulate, surfaces glabrous or with scattered bristles on one or both surfaces;

cauline similar to basal except: stipules deltate to lanceolate, margins entire or sparingly toothed;
