Justification:
All subpopulations are small and severely fragmented. More than 50% of the total population is within small subpopulations and the majority of locations are more than 50 km apart, making genetic exchange or recolonization unlikely. The extent of occurrence is considerably less than 5,000 km²and the area of occupancy is also likely to be well under 500 km², and there is continuing decline in all parameters with some probably complete loss of certain subpopulations. Subpopulations located in mining areas will disappear in the near future either as a direct result of mining, activities associated with mining (road building, spoil dumping) or an increase in fires. Coastal sites are threatened by erosion, the expansion of settlements and may also be susceptible to sea level rises. No subpopulations are within protected areas.

History:

1998	–	Endangered (Oldfield et al. 1998)
1998	–	Endangered
1997	–	Endangered (Walter and Gillett 1998)

Geographic Range [top]

Range Description:	Small subpopulations are confined to fewer than ten locations in the central and southern part of the island with an isolated, disjunct subpopulation on the Ile d'Art. Has been recorded from near sea level up to 1,000 m.
Countries:	Native: New Caledonia

Population [top]

Population:	There are extimated to be less than 2,500 mature individuals with no subpopulation containing more than 250.
Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	Restricted to ultramafic soils along the coast and in inland areas. Usually found in humid evergreen forest, often on cliffs, along streams and on steep slopes.
Systems:	Terrestrial

Threats [top]

Major Threat(s):	None of the populations are protected and in places, e.g., in Plum they are seriously threatened by fire and erosion. Mining and the increasing settlement in other locations are also concerns.
