Odontarrhena is a large genus of flowering plants in the family Brassicaceae. They were originally a separate genus and then were amalgamated into the Alyssum genus, but morphological and molecular evidence has reseparated them. Some of the genera are nickel (Ni) hyperaccumulators (a plant capable of growing in soil or water with very high concentrations of metals).
