Description complète des menacesTexte détaillé évaluation IUCNExpert
The habitat in most of the sites where this species occurs have been heavily degraded by forest clearance for agriculture and plantations. All populations are threatened by factors which affect all plants occurring in flowing water bodies in the region, notably forest clearance, urbanisation, agricultural intensification and the secondary effects of these factors, particularly increased turbidity, pollution and casual habitat degradation. The species may be threatened by commercial collection.
