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 and is declining. 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. The plant is classified as 'Critically Endangered' in the IUCN Red List of Threatened Species(2013)[
