- Habitat: Stony and sandy soils, on coastal rocky slopes, at up to 680 m altitude
- Description: Shrubby or tree-like species ranging from the Cape Region through Namibia and into Angola. Stems are 4-5 angled and bordered with pairs of spines. The main central stem often spirals but the branches rarely (or never) do.

This species forms clumps about a meter in diameter with a very extensive root system to take advantage of the heavy fogs of the Namib Desert.
