blade purplish, purple-tinted, or gray-green abaxially, gray, green, or gray-green adaxially, sometimes shiny adaxially, ovate, orbiculate, oblong, deltate, or lanceolate, 0.8–5.3 × 0.4–4.1 cm, often fleshy, base cordate, subcordate, truncate, or attenuate, oblique or not, margins usually ± crenate, serrate, dentate, or coarsely or irregularly repand-dentate, sometimes entire, usually ciliate, apex acute to obtuse or rounded, surfaces glabrous, puberulent, or tomentose;

cauline similar to basal except: stipules linear, lanceolate, oblanceolate, or ± oblong to ovate, margins entire, lacerate, or laciniate, usually ciliate, apex sometimes divided into 2–3 filiform processes or obtuse;
