New aluminum hyperaccumulator species of the Proteaceae family from southern South America

Aims Considering that some members of the Proteaceae family are aluminum (Al) and manganese (Mn)–hyperaccumulating species, we aimed to evaluate the presence of the metal hyperaccumulation trait in the Proteaceae family inhabiting southern South America. We also questioned whether other metals (e.g. iron (Fe), copper (Cu) and zinc (Zn)) are hyperaccumulated in the leaves of these species.
