Description complète des menacesTexte détaillé évaluation IUCNExpert
The species is likely to be extremely vulnerable to local and even very small-scale actions which affect the water bodies in which it grows, such as logging of catchments, development or pollution. Recently it has become apparent that two of the sites from which it has been recorded are much disturbed (Nguyen et al. 2014). It may also be threatened by commercial collecting, as known subpopulations appear to be small.

It was assessed as Vulnerable (VU A2a; B2ab(ii,iii); C1) by Nguyen et al. (2014). Remaining populations occur in protected, areas to one of which access is only permitted for scientific research. However, it is not clear whether this protection is enough to prevent collection for commercial sale. There is an urgent need for surveys to locate and document extant populations.
