basal and cauline;

petiolate or sessile;

basal rosulate, petiolate or sessile, blade margins usually entire or dentate to denticulate, rarely lyrate-pinnatifid;

cauline usually sessile, rarely shortly petiolate, blade (base often auriculate, sagittate, or amplexicaul), margins entire or dentate.

petiole (0.7–)2–5 cm;

blade usually ovate to oblanceolate, rarely cordate, (0.8–)1.5–3 cm × 5–17 mm, margins dentate or serrate, surfaces sparsely to densely pubescent, trichomes simple or forked.

(5–)8–20(–27), (overlapping or not);

blade ovate to oblong or lanceolate, (2–)3–7.5(–9) cm × (10–)13–25(–35) mm, base amplexicaul, margins usually dentate or serrate, sometimes entire, surfaces hirsute.

(sometimes paniculate, usually simple, sometimes branched).

branched.

sepals erect or ascending, ovate or oblong, lateral pair saccate or not basally, (margins membranous);
