Berteroa is a genus of five species, all native to southeastern, eastern and Central Europe. One species, Berteroa incana, is now a widespread weedy species in many parts of the world.
All Berteroa species are closely related and form a monophyletic group. They are morphologically characterized by being annuals to perennials with simple racemes, white, yellow or pink flowers with deeply bifid petals, an indumentum of stellate hairs, sometimes mixed with simple hairs, and multi-seeded fruits (Warwick & al. 2008). Berteroa and Aurinia are closely similar and this resemblance is confirmed by molecular data (Warwick & al. 2008, Rešetnik & al. 2013). Together with Galitzkya these genera form a distinct clade (the Aurinia clade).
