État de la populationTexte officiel évaluation IUCNExpert
This species typically forms dense stands. There is no information on population size or trends. Whilst all known subpopulations occur within or adjacent to areas which have been cleared for cultivation and most are considered likely to be declining as a consequence of habitat degradation, continuing decline requires confirmation.

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. All known subpopulations occur within or adjacent to areas which have been cleared for cultivation and all of the southern sites are very vulnerable to expansion of existing settlements. The species may be severely threatened by over-collection.
