| Habitat notes | Endemic to Rapa Nui (Easter Island). The last tree seen growing alive in the wild was in the crater Rano Kao by Heyerdahl in 1958. Seed were collected and given to Kew which have been attempted to reintegrate back to the island. A couple of trees are growing in cultivated gardens by CONAF. The tree generally grows between boulders which sheltered from wind and provided moisture to the tree. Some seeds can float with viability in sea water for up to 3 years. |
