Justification | An endemic to the Namaqualand region of South Africa, this species is a highly localized habitat specialist with an extent of occurrence (EOO) of 73 km² and an area of occupancy (AOO) of 20 km². It is known from five locations and there is ongoing decline as result of illegal collecting and degradation of this species habitat due to livestock overgrazing and trampling. It therefore qualifies as Endangered under criterion B. |

Threats |
| This taxon is a highly unusual Conophytum popular in cultivation. Collection of plants from the wild was a threat in the past, and there is recent evidence of illegal harvest and trade once again taking place. Since March 2019 there has been a marked increase in the demand for Conophytum species coming from Asian countries and poaching has escalated significantly. Subpopulations in accessible places near roads are experiencing the most decline. Furthermore large areas of the Kamiesberg are communally owned, and severely overstocked with livestock. Livestock is causing ongoing degradation of its habitat. |
Population |
This species is a highly localized habitat specialist. It is known from five locations where it is locally abundant in suitable habitat. The population is estimated to exceed 5000 plants but is declining.
