Biennials or, rarely, perennials; glabrous throughout or margins ciliate. Stems (1.5–)2–9(–12) dm. Basal leaves: petiole (0.5–)2–10(–17) cm; blade lyrate-pinnatifid, (1–)2–8(–10) cm, lobes 1–3(–5) on each side (rarely early ones undivided), lateral lobes oblong or ovate, 0.3–2(–4) cm × 1–8(–15) mm, sometimes slightly fleshy, margins entire, repand, crenate, or dentate, terminal lobe (ovate or suborbicular), (0.7–)1.5–4.5(–7) cm × (4–)10–30(–50) mm, (surfaces glabrous or margins ciliate). Cauline leaves: blade ovate or suborbicular (undivided), margins usually coarsely dentate, rarely subentire; conspicuously auriculate, auricles ovate or narrowly oblong (to 10 × 5 mm), glabrous. Fruiting pedicels divaricate to ascending or erect, 3–7 mm, terete or subquadrangular, thickened (narrower than fruit). Flowers: sepals 3–4.5(–5) × 1–1.5 mm, lateral pair slightly saccate basally, margins scarious; petals yellow, spatulate or oblanceolate, (5–)6–9(–10) × 1.5–2.5(–3.5) mm, base attenuate, apex rounded; filaments 3–4.5 mm; anthers 0.7–1.2 mm; ovules 18–24(–28) per ovary; gynophore to 0.5 mm. Fruits erect to erect-ascending, rarely appressed to rachis, torulose, terete, somewhat compressed, or 4-angled, (0.7–)1.5–3 cm × 1.2–2 mm; style slender, (1–)1.5–3(–3.5) mm. Seeds dark brown, plump, broadly ovoid to oblong or subglobose, 1.2–1.5 × 1–1.2 mm. 2n = 16.
