Basal leaves petiolate, rosulate, simple, entire, coarsely dentate, or lyrate, with persistent petioles. Cauline leaves absent, if present sessile or shortly petiolate, entire. Racemes few to many flowered, ebracteate or rarely lowermost flowers bracteate, elongated in fruit. Fruiting pedicels slender, suberect or divaricate. Sepals ovate or oblong, persistent or caducous, base of lateral pair not saccate. Petals pink or violet, rarely white with purplish claws, obovate, apex obtuse or emarginate; claw subequaling sepals. Stamens 6, tetradynamous; filaments dilated at base; anthers ovate or oblong, obtuse at apex. Nectar glands confluent and subtending bases of all stamens; median glands present; lateral glands often annular. Ovules 10-18 per ovary. Fruit dehiscent siliques or silicles, linear, oblong, ovoid, lanceolate, or ellipsoid, terete or latiseptate, sessile or shortly stipitate; valves with a distinct midvein, smooth or torulose; replum rounded; septum complete, membranous, translucent; style obsolete to 2.5 mm, persistent; stigma capitate, entire or rarely 2-lobed, Seeds uniseriate, wingless, oblong, plump; seed coat reticulate, not mucilaginous when wetted; cotyledons incumbent.
