in Northern Province

Oxera neriifolia subsp. sororia is a woody climber endemic to New Caledonia, restricted to the north west of Grande Terre. It is found in shrubland on ultramafic substrate between 350 and 700 m asl. Known from three locations, its extent of occurrence (EOO) and area of occupancy (AOO) are 105 and 16 km², respectively. The main threat is past and ongoing mining activities in Kopéto and Boulinda, but uncontrolled bushfires could also affect this taxon. However, due to a lack of recent observations and taxonomic doubts, Oxera neriifolia subsp. sororia is listed as Data Deficient (DD).
