Justification
A highly range-restricted species from the Richtersveld South Africa, it occurs in an area of less than 1 km², and is only known from a single population occurring at one location. The extent of occurrence (EOO) and area of occupancy (AOO) is 4 km². This species is potentially threatened by illegal harvesting as it is very popular in cultivation. It therefore qualifies as vulnerable under criterion D2.
