Notes
This is the most recently described Oryza species and was restricted to about 1 ha of sclerophyll forest near the town of Poumbout. In part due to fire sclerophyll forests are among the most endangered habitats in New Caledonia ? the only place this species has been reported. Thus its continued existence in the wild is not assured but still exists in 2007.
