Annual herbs or perennial shrubs, erect, glabrous, papillose or with simple hairs. Leaves petiolate, entire to 2- or 3-times divided, segments narrow. Inflorescence a dense or elongated raceme. Sepals initially erect but spreading to horizontal; petals clawed, yellow to white; stamens 6. Fruit linear, straight or slightly curved, elongate (more than 3 times as long as broad), dehiscent; style small and bilobed; valves with distinct midvein; seeds in 1 or 2 rows per locule. (Entire description applies to Victorian plants only.)

6 species, endemic to semi-arid regions of Australia.

Among those Brassicaceae with dehiscent fruits and yellow petals, Arabidella in Victoria can be distinguished by the glabrous or papillose stems and the linear fruits with a capitate persistent style.
