The palm has a large distribution range (extent of occurrence is over 58,000 km²) but it is not common in any of the current known sites. The population is estimated to only number 30 mature trees. The leaves of this species are exploited by local people for weaving hats and individual palms may be pruned into juvenility by constant harvest of the emerging leaves. This species is listed as Critically Endangered based on the small population size, this is a genuine deterioration since the 1998 listing of Endangered.
|Previously published Red List assessments:||

|Population:||This species has an extremely wide range but at each of the known sites there are only a few individuals. The population is estimated to number fewer than 30 mature trees. The population is declining.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||Occurs in moist lowland forest on slight mid slopes or ridge crests from 50 to 1,200 m..|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Use and Trade:||The leaves are harvested and used for weaving hats and other handicrafts.|
|Major Threat(s):||The main threats to this species are habitat loss through clearance for shifting agriculture and logging and harvesting of the leaves to be used in weaving. Excessive harvesting impacts the reproductive output of the species.|
|Conservation Actions:||Protected in Masoala, Makira and Andasibe. Regulation and monitoring of the harvest may be required.|
