Pentecost Island
"Oxera vanuatuensis" is only known from Vanuatu, where it is only known from cultivated specimens. Villagers on Pentecost Island (and their descendants on Maewo call the tree "harongmau", and propagate the species by planting seeds, transplanting seedlings or taking cuttings. The plant is thought to treat illnesses caused by black magic, and profuse flowering from the trunk is thought to foretell a good harvest of yams.
