État de la populationTexte officiel évaluation IUCNExpert
There is no information available on population size in this species, however, population declines are occurring due to the secondary effects of deforestation (Ipor et al. 2007).

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. Forest clearance for agriculture and oil plantations increases the flow rate and sediment movements in rivers and as a result, populations of this species are covered by sediment deposits leading to their decline and loss (Ipor et al. 2007). It is also threatened by collection from the wild for the plant trade.
