État de la populationTexte officiel évaluation IUCNExpert
There are around 10 subpopulations (eight precise localities), three of which are probably extinct. A 30% decline in population can be in inferred. This species is considered severely fragmented as > 50 % of its known localities are isolated from one another and the seeds are known to be dispersed in water (van Brugen 1985) and it is thus presumed that dispersal between isolated water bodies occurs very seldom.

Description complète des menacesTexte détaillé évaluation IUCNExpert
Drying up of vleis associated with urbanisation. Four of the 12 recorded locations in PRECIS have been lost due to urbanisation of Cape Town and Stellenbosch over the past 120 years. According to J. Day (pers. comm.) there has been at least a 30 % loss of habitat in the past 50 years.
The species seems to be able to deal with the invasion of alien grasses such as Paspalum vaginatum.
