Year Published: 2012

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.
