Basal leaves petiolate, mostly rosulate, simple, entire, dentate, or lyrate-pinnatifid; cauline leaves sessile, not auriculate or sagittate, entire, dentate, or pinnatifid. Racemes several-flowered, ebracteate, corymbose, elongated considerably in fruit; rachis straight; fruiting pedicels ascending to subdivaricate, persistent.

Stamens 6, slightly exserted, slightly tetradynamous; filaments wingless, unappendaged, glabrous, free; anthers ovate or oblong, obtuse at apex. Nectar glands confluent, subtending bases of all stamens; median glands present. Ovules 12–30 per ovary. Fruit dehiscent capsular siliques, linear, subterete to strongly flattened parallel to septum, not inflated, unsegmented; valves not thickened, without or with obscure midvein along the proximal half, pubescent or glabrescent, not keeled, slightly to strongly torulose, wingless, unappendaged; gynophore less than 1 mm; replum rounded, visible; septum complete, membranous, not veined; style obsolete or to 1.3 mm; stigma capitate, entire, unappendaged.
