A range-restricted endemic to the Richtersveld region of South Africa, with an extent of occurrence (EOO) of 691 km² and an area of occupancy (AOO) of 48 km². Between eight and ten threat defined locations have subpopulations that are experiencing ongoing decline in mature individuals as a result of illegal poaching and the impact of a prolonged drought in the region. This taxon therefore qualifies for listing as Vulnerable under criterion B.

Succulent Karoo
Quartz flats in various types of succulent shrubland.
Possibly half of the population in the Richtersveld died from the prolonged drought between 2016 and 2020. Online trading of habitat collected specimens from Eksteenfontein was recorded in 2019, illegal collecting is an ongoing pressure to this taxon, in 2009 there were reports of poachers collecting this species in the Eksteenfontein area in large quantities. After revisiting two populations shortly after the report, one population was completely depleted and the other had half of the plants removed. In September 2019 not a single plant could be found at this location. This taxon is therefore experiencing ongoing decline.

Widespread with scattered individuals, sometimes locally common. Numbers have been decreasing continuously as a result of illegal harvesting and drought related mortality.
