Red List Category & Criteria: Critically Endangered B1ab(ii,iii,v)+2b(ii,iii,v) ver 3.1
Year Published: 2012

Endemic to one river to the north of Taolagnaro. Individuals are known from one unprotected locality. The extent of occurrence and area of occupancy are both less than 4 km². The species is relatively abundant with a population of about 450 trees. Plants and seed are harvested for the horticultural trade. Trunks are sometimes felled to make temporary canoes and there is clearance of the vegetation along the river which decreases the area of occupancy. The species therefore qualifies for listing as Critically Endangered.
