Biennial to perennial herbs; glabrous or with unbranched hairs. Leaves pinnatifid or pinnatisect, the cauline amplexicaul. Inner sepals slightly saccate at base; petals yellow, clawed. Fruit a siliqua, 4-angled; valves usually with a strong median vein and reticulate lateral veins; style distinct; stigma slightly 2-lobed. Seeds in 1 row in each loculus.

All species occur usually in wet or damp habitats.
