Leaves basal and cauline; petiolate; basal (often withered by anthesis or fruiting), rosulate, long-petiolate, blade margins crenate, dentate, or sinuate; cauline shortly petiolate, blade margins dentate. Racemes elongated in fruit. Fruiting pedicels divaricate or ascending, stout (almost as broad as fruit [slender, narrower than fruit]). Flowers: sepals erect, oblong, lateral pair not saccate basally, (glabrous); petals oblanceolate, (longer than sepals), claw obscurely differentiated from blade, (apex obtuse); stamens slightly tetradynamous; filaments not dilated basally; anthers ovate or oblong, (apex obtuse); nectar glands confluent, subtending bases of stamens. Fruits siliques, sessile, linear [oblong], torulose or subtorulose, terete, subterete, or 4-angled; valves each with prominent midvein and distinct marginal veins, glabrous [scabrous]; replum rounded; septum complete; ovules [4–] 6–22 per ovary; style obsolete or distinct (to 6 mm); stigma capitate, entire. Seeds plump, not winged, oblong; seed-coat (longitudinally striate), not mucilaginous when wetted; cotyledons incumbent.
