Occasional littoral palm in northeast Madagascar, recorded from five fragmented locations (Ambila-lemaitso, Mahavelona, Soanierana Ivongo, Sainte Marie and Antalaha). The extent of occurrence and area of occupancy are estimated to be 4,234 km² and 112 km² respectively. These sites are all threatened by vegetation loss and the species is affected by the continuing reduction of the quality of habitat. Soanierana Ivongo has the largest subpopulation with about 100 clumps, elsewhere this palm is scattered with few individuals only (the whole population comprises less than 200 clumps).  The species therefore qualifies for listing as Endangered.
