Where it grows wild

No wild records with coordinates exist, so the habitat is inferred from the genus: small Karoo euphorbias grow in open, stony dwarf shrubland, often among quartz or shale pebbles with only the tips exposed.

Unknown for this species; the climate site used is a regional point at about 1,040 m in the Northern Cape interior.
