Flora of Easter Island

Sophora toromiro, commonly known as toromiro, is a species of flowering tree in the legume family, Fabaceae, that is endemic to Easter Island. Sophora toromiro is extinct in the wild due to overharvesting and overgrazing, but some individuals survive in botanical and private collections. It holds significant cultural importance for the Rapa Nui people, known for its statues, ceremonial objects, and other tools made from the wood. The species serves as proof that human intervention of a natural environment can drastically change the composition of native flora negatively, even to the point of

Several species are known by the common name scaly polypody and resurrection fern. The genus is closely related to Polypodium. Many of the species have been or sometimes are still included in that genus. Further changes in the circumscription of the genus may occur as research continues.
