Description complète des menacesTexte détaillé évaluation IUCNExpert

The natural vegetation has been degraded and fragmented through conversion to agricultural land, coca plantations and urban development. Threats may be reduced on steep and inaccessible slopes. The impact of anthropogenic disturbance on the population of this species is unknown. The taxon has been collected in logged primary forest, however, its ability to regenerate in secondary forest is unknown. It is cultivated as an ornamental plant. The impact of potential collection for the horticultural trade on the population is unknown.
