Perennials, (usually suffrutescent, roots with shoots from adventitious-buds), strongly scented (with glucosinolates), (glaucescent). Stems erect, 2–7 (–10) dm, glabrescent or sparsely pubescent basally. Basal leaves: blade elliptic to obovate, 2–15 cm × 10–60 (–80) mm, margins sinuate to deeply pinnatifid, (2–5 lobes each side). Cauline leaves petiolate; similar to basal, (distal cauline shortly petiolate, blade similar, with narrower segments), surfaces usually glabrescent. Fruiting pedicels 8–35 mm. Flowers: sepals 4–6 mm, glabrous or pubescent, trichomes straight; petals yellow, 7–11 (–13) × 5–8 mm, (apex rounded); filaments 4–8 mm; anthers 2.5–3 mm; gynophore 0.5–3 mm. Fruits usually erect, rarely ascending, (somewhat torulose, slightly compressed), 2–5 cm × 1.5–2.5 mm; terminal segment (stout), beaklike, 1.5–3 mm, seedless; (ovules 20–32 (–46) per ovary). Seeds 1–1.3 × 0.6–0.9 mm. 2n = 22.


Phenology: Flowering spring–fall.
Habitat: Waste places, disturbed areas, wharf and railroad ballast, sandy beaches, muddy shores, wet woods, mountain slopes
