Stems simple to several from base, erect, often outer decumbent, (unbranched or branched distally), 1-7 dm. Basal leaves: blade oblanceolate to elliptic, 1.5-8(-11.5) cm, margins lyrate-pinnatifid to dentate or repand, (abaxial surface densely pubescent, adaxial sparsely pubescent). Cauline leaves: (proximal petiolate, distal sessile); blade oblanceolate to oblong, 1-7 cm, margins dentate to repand. Racemes loose, (elongated). Fruiting pedicels (usually divaricate-spreading, sometimes horizontal or shallowly recurved, straight or slightly curved), (7-)10-20(-25) mm, (slender or stout). Flowers: sepals elliptic or broadly ovate, 3-6.5(-8) mm, (median pair slightly thickened apically, cucullate); petals (yellow to orange), broadly obovate, 6-11 mm, (narrowing gradually to short claw). Fruits (stipitate or subsessile, gynophore 1-2 mm), globose, subglobose, obpyriform, or obovoid, not or slightly inflated, 3-9 mm; valves (not retaining seeds after dehiscence), glabrous throughout or sparsely pubescent inside; replum as wide as or wider than fruit; ovules 8-20(-28) per ovary; style 2-4.5 mm.
