What kind of trees grow on Easter Island?

All most all of the plants on Rapa Nui (Easter Island) are exotics, introduced. They have been brought for food, horticulture, landscape and by accident. I am in the process of producing a current species list and other papers on the plant life here on the island. Some of the plants there are very exotic. Most of them are very rare. Rare plants are plants that you don't see very often.
