Justification | A range-restricted endemic to the Namaqualand region of South Africa, it has an extent of occurrence (EOO) and area of occupancy (AOO) of 8 km². Two threat based locations are potentially threatened by illegal succulent collecting. This species therefore qualifies as Vulnerable under criterion D2. |

Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Succulent Karoo |
Description | Shaded cracks and crevices in gneiss outcrops. |
Threats |
| This localised species is potentially threatened by illegal collecting for the specialist succulent horticultural trade. There has been a marked increase in Conophytum trafficking to Asian countries since March 2019. |
Population |
This species is known from two large subpopulations, about 4 km apart, and each numbering several hundred plants. It is possibly to be overlooked and more common than records suggest, as its habitat remains poorly explored. The population is estimated to be larger than 1000 mature individuals, but has the potential to decline as result of illegal collecting.
