This is a palm of the high plateau between Fianarantsoa and Andilamena. The populations are fragmented and known only from eight localities where the habitat is periodically burnt. The area of occupancy is only 1,430 km², hence this species qualifies for a Vulnerable listing.
The species is threatened by the increasing frequency of fires and by over-exploitation of the seed for the horticultural trade. Any trade would be illegal as the species is listed on CITES Appendix I.
