Stems several from base, erect to decumbent or prostrate, (unbranched or branched, sometimes densely leaved), 1-3.5(-4.5) dm. Basal leaves: blade obovate to broadly oblong, 1.5-5(-8) cm, margins lyrate-pinnatifid, dentate, or entire. Cauline leaves: (proximal sometimes petiolate, distal sessile); blade linear to oblanceolate, often falcate, 1-4(-7) cm, (proximal with base sometimes cuneate), margins entire, repand, or shallowly dentate. Racemes dense. Fruiting pedicels (divaricate-ascending, sigmoid or, sometimes, nearly straight), 5-15(-25) mm. Flowers: sepals elliptic or oblong, 3-6.5 mm, (lateral pair subsaccate, median pair thickened apically, cucullate); petals (widely spreading at anthesis, yellow to orange, claw sometimes whitish), cuneate, obdeltate, or obovate, (tapering to claw), 5-8(-10) mm, (claw often widened at base). Fruits (shortly stipitate), subglobose, not or slightly compressed, (3-)4-8 mm; valves (not retaining seeds after dehiscence), glabrous throughout; replum as wide as or wider than fruit; ovules (8-) 12-20(-26) per ovary; style (1.5-)2-4(-5) mm. Seeds flattened. 2n = 12, 32.
