Basal leaves petiolate, not rosulate, simple, 2-pinnatisect. Cauline leaves petiolate or uppermost subsessile, 1- or 2-pinnatisect, rarely pinnatifid. Racemes ebracteate, bracteate throughout, or only basally bracteate. Fruiting pedicels erect, ascending, or divaricate. Sepals oblong or ovate-oblong, ascending, base of lateral pair not saccate. Petals yellow, shorter or much longer than sepals; blade obovate or spatulate, apex rounded; claw slightly to strongly differentiated from blade, shorter than to as long as sepals. Stamens 6, slightly tetradynamous; filaments not dilated at base; anthers ovate or oblong, obtuse at apex. Nectar glands confluent and subtending bases of all stamens; median glands present; lateral glands semiannular. Ovules 4-16 per ovary. Fruit dehiscent siliques or silicles, linear, oblong, obovoid, or ellipsoid, terete or slightly 4-angled, sessile or shortly stipitate; valves with an obscure to prominent midvein, glabrous, smooth or subtorulose; replum rounded; septum complete or basally perforated, membranous; style obsolete or short and less than 1 mm; stigma capitate, entire.
