Odontarrhena
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 accumulating metals from soil or water, up to very high concentrations in the plant).
About 48 members of the Odontarrhena species, are known to be nickel (Ni) hyperaccumulators (a plant capable of accumulating metals from soil or water, up to very high concentrations in the plant). The accumulation of nickel was first discovered in the Italian endemic Odontarrhena bertolonii (Desv.) Jord. and Fourr. (syn. Alyssum bertolonii Desv. by Minguzzi and Vergnano in 1948, Of the 168 or so species of Alyssum, 45 species were determined to be hyperaccumulators of nickel, all from the Odontarrhena section. The metal is found in the roots, stem, leaves and flowers of the plant.
