Status and Criteria | Critically Endangered (Possibly Extinct) |
Assessment Date | 2021/06/22 |
Assessor(s) | P. Goldblatt, D. Raimondo & T. Patel |
Justification | This species was known from one location from the type locality, growing on granite rocks at Vredenburg. Repeated visits to the presumed type locality (a cluster of granite boulders on the edge of Vredenburg) have failed to relocate it. Moderate disturbance makes it unlikely that the species is extinct due to human activity. Nevertheless, it is considered Critically Endangered Possibly Extinct. |
