Description complète des menacesTexte détaillé évaluation IUCNExpert
The habitats and sites where this species occurs 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. Collection from the wild for the ornamental plant trade is a possible threat, but it is unlikely to be vulnerable to commercial collection because of the ease of propagation.
