| Habitat notes | A deciduous tree growing to 15 meters. Fast growing, when introduced to non-native environments can quickly disrupt the native habitat as it chokes out native flora because of its very high consumption of water. Root system shallow and easily is blown down by winds. Skottsberg noted abundance in the crater of Rano Kao in 1904 but mostly immature. Gossen noted in March 2008 that the species was limited to the NW crater side as small shrubs up to 2m tall. (Also noted in the fossil record of KAO3). |
