Herbs, annual or perennial erect branching, glabrous or with simple hairs; taproot slender. Leaves simple to deeply lyrate-pinnate, glabrous or sparsely pilose. Flowers in bracteate or ebracteate racemes, yellow. Sepals scarcely saccate at base; inner sepals pouched at base. Petals yellow, as long as or longer than sepals or absent. Stamens 6 or sometimes 4. Ovary oblong to suborbicular, many-ovuled; stigma slightly bilobed. Fruits linear, cylindrical or ellipsoid, bilocular, dehiscent; valves with indistinct midrib; style short; stigma rounded. Seeds suborbicular, few to numerous, more or less biseriate, reddish-brown.

Mostly in northern temperate zone; about 90 species, 7 in India.

Notes. Sometimes considered congeneric with Nasturtium R. Br. In that case the correct name for the combined genus would be Rorippa Scop.
