Justification | A range-restricted species from the Richtersveld region of South Africa, with an extent of occurrence (EOO) of 386 km² and an area of occupancy (AOO) of 48 km². Nine threat based locations are declining due to ongoing and escalating collecting for the specialist succulent horticultural trade. This species therefore qualifies for listing as Vulnerable under criterion B. |
