Basal leaves: petiole to 10 cm; blade lyrate-pinnatifid to sinuate-lobed, 6-30 cm × 10-100 mm, lobes 1-3 each side, (smaller than terminal, terminal lobe ovate, obtuse). Cauline leaves sessile or subsessile; blade (ovate-elliptic to lanceolate, similar to basal, reduced distally and less divided), base tapered, not auriculate or amplexicaul, (margins entire to sinuate-serrate). Racemes not paniculately branched. Fruiting pedicels erect (straight), (2-)3-5(-6) mm. Flowers: sepals 4-6(-7) × 1-1.5 mm; petals yellow, ovate, 7-11(-13) × (2.5-)3-4.5(-5.5) mm, claw 3-6 mm, apex rounded; filaments 3.5-5 mm; anthers 1-1.5 mm. Fruits erect-ascending (± appressed to rachis), smooth, ± 4-angled, 1-2.5(-2.7) cm × (1.5-) 2-3(-4) mm; valvular segment 2-5(-8)-seeded per locule, (0.4-)0.8-2(-2.5) cm, terminal segment seedless (linear, narrow), (1-)2-5(-6) mm. Seeds brown to black, 1.2-1.5(-2) mm diam.; seed coat coarsely reticulate, minutely alveolate, not mucilaginous when wetted. 2 n = 16.

It occurs only sporadically in southern Canada but most frequently in Ontario and along the St. Lawrence River. Specimens from Alberta, Arkansas, Delaware, and South Carolina have not been observed.
