erect, branched distally, (2–)3.5–12(–17.5) dm, often densely hispid proximally, (trichomes retrorse), usually glabrous distally.

(simple or few to several from base), erect or ascending to subprostrate, branched distally, 1–5(–7) dm, glabrous.

rosulate;

petiole 1–4(–5) cm;

blade broadly oblanceolate (in outline), (1.5–)2.5–8(–12) cm × (10–)20–50(–70) mm, margins runcinate to lyrate-pinnatifid;

lobes 2–4 on each side, much smaller than terminal lobe, margins entire or dentate, (terminal lobe triangular, often hastate).

(soon withered); initially rosulate;

petiole (1–)2–5(–6.5) cm;

blade oblanceolate to lanceolate (in outline), 2–7(–10) cm × 10–30(–45) mm, margins sinuate- or runcinate-pinnatifid to coarsely dentate;

lobes 3–6 on each side, often triangular, slightly smaller than terminal lobe, margins dentate or subentire.

similar to basal;

blade (much smaller than basal, to 1.5 cm wide), margins entire or toothed.

(sometimes bracts, several), similar to basal, (shortly petiolate);

blade margins dentate or subentire, (surfaces glabrous or sparsely puberulent at and near margin). (Inflorescences 2–4(–6)-fasciculate, or flowers solitary and axillary, bracteate throughout.) Fruiting pedicels ascending to erect, stout, narrower than fruit base, 0.5–1(–2) mm.
