Stems several from base, erect or outer ones decumbent or procumbent, (sometimes much-branched distally), to 6 dm. Basal leaves: blade obovate or rhombic, to ca. 2.5 cm, margins usually shallowly dentate, sometimes lyrate-pinnatifid. Cauline leaves: (proximal shortly petiolate, distal sessile); blade obovate to rhombic or oblanceolate, 2-4(-6) cm, margins entire or shallowly and remotely dentate. Racemes usually dense, (several-flowered). Fruiting pedicels (strongly recurved), to 20 mm. Flowers: sepals ovate or oblong (tapering at base), 3.6-4.8(-5.3) mm, (lateral pair subsaccate, median pair thickened apically, cucullate); petals obovate to spatulate, 4.5-7.5 mm, (blade narrowed to broad claw, margins sinuate). Fruits (± pendent), ovoid, obcompressed, or globose, compressed, 4-6(-8) mm; valves (not retaining seeds after dehiscence), sparsely pubescent or glabrous, sparsely pubescent inside; replum as wide as or wider than fruit; ovules usually 4, rarely 6, per ovary; style 2.5-3.6 mm.
