Multisternmed, spineless, much-branched, succulent shrub, forming bright green to grey-green clumps, very variable in size, but usually between 0.4-1.2 m high. Flowering branches usually yellowish-green but may be grey-green, 5-8 mm in cross-section. Inflorescence a flat-topped terminal cluster. Glands bright, shiny yellow, margin entire. Flowering winter to early summer. Capsules yellow-green or flushed pink, on curved stalks, about 6 mm in cross-section, 3-angled, smooth, usually green until mature. This species is often common where it occurs, usually on gravelly-sandy slopes or plains, Large, robust individuals of this widespread species may be confused with E. dregeana. The differences are discussed under that species. Very big individuals resemble E. gumraifero, but only when sterile, as the inflorescences differ. A number of different varieties of E. rnauritanica occur from central to southern Namibia, and several of them also occur in South Africa. It may be seen on Namuskluft, on slopes of the Aurus basin, and on or near other koppies and mountains. (from Wildflowers of the southern Namib by Coleen Mannheimer)
