Diffuse succulent shrublet branching well above ground level from a single centrally rooted stem. Stems 100-500 mm long, 10-15(-20) mm thick, erect then spreading horizontally and somewhat tapering towards apex, greyish green to dark purple-grey or almost black especially on young growth; tubercles <2 mm long, obtuse and very obscure, joined into 4(rarely 5) obtuse and obscure angles along stem, each bearing a minute hard-tipped tooth in the middle. Inflorescences of 1-3 usually successively opening flowers towards tips of stems; pedicel 2-8 mm long, 0.5-1.0 mm thick, spreading and holding flower facing horizontally; sepals 1-2 mm long, ovate-acute. Corolla 7-13 mm diam., rotate; outside grey-green to mottled or suffused with purple-brown; inside somewhat rugulose, dark maroon (almost black) sometimes with white ring around corona, covered with fine crinkled white hairs up to 1 mm long; tube ±0.5 mm long, containing less than half of column, very broadly conical to ± absent, with corolla thickened around mouth; lobes (2-)3-5 mm long, 2.5-3.0 mm broad at base, deltate to deltate-lanceolate or ovate, acute, spreading. Corona 2 mm tall, 2.2-2.5 mm broad (usually nearly as tall as broad), black becoming reddish towards base, narrowing gradually towards base without obvious stipe; outer lobes with free part <0.5 mm long, erect, shallowly bifid into small erect deltoid teeth, laterally fused for most of length with lower outer sides of inner lobes to form pouches enclosing guide-rails; inner lobes <1 mm long, adpressed to backs of anthers and exceeding them, linear to deltoid with notched to obtuse apex, dorsiventrally flattened, with short ridge-like often spreading dorsal projection near base a little above outer lobes.

Corolla rotate, 7-13 mm diam., inside dark maroon, tube absent, lobes spreading, deltoid, 3-5 x 2.5-3 mm.

Specimens of Q. pruinosa are quite remarkably distinctive in their growth form and they can usually be recognised without flowers. The plant is almost always rooted by the primary stem only, although, unlike in some species with this habit, cuttings are quite easy to root in cultivation. Although initially erect, the stems tend to spread out horizontally after some distance, often all tending to point in a particular direction, giving the plant an odd, ‘windswept’ appearance. This strange growth habit is usually quite obvious in large plants which project from their protective shrub, exposing their upper parts fully to the elements and eventually looking much like old, weathered twigs. It is similar to the growth habit of many species of Rhytidocaulon. Large specimens may be anything between 0.5 m and even 0.75 m in diameter but the branching is relatively sparse and they do not form dense shrubs as do some of the other larger species. Unlike all other species in Namaqualand, Q. pruinosa has relatively slender, 4-angled stems that are rounded and the tubercles are obscure, each tipped by only a small, often nearly obsolete tooth. Young stems are usually very dark, often nearly black (as in Q. linearis) and later tend to become purple-grey with a thick covering of wax. In Q. pruinosa the flowers are fairly small (usually around 10 mm across) and flat and are held slightly away from the stems. They emit a remarkably strong, lemon-like scent for a few hours after they open (usually for less than six hours) but after this passes, they are odourless. On the inside, the background colour of the corolla is usually dark maroon to almost black, although in some specimens this dark colour becomes paler maroon around the base and changes to a ring of white around the corona. In many plants this dark background colour dominates the flower so that they are not very conspicuous against the stems. Their interior is covered (in most cases) with a dense, entangled mat of fine, white, crinkled hairs which, depending on their length and denseness, can lighten the basic colour to grey and sometimes give it the ‘frosted’ appearance that caused Masson to name this species Stapelia pruinosa. This hairiness bears some resemblance also to a dense covering of mildew. Some of these hairs seem to cling to the sides of the corona, which might be slightly sticky, and in so doing they form a spiderweb-like covering of the small space around the gynostegium. The corona is mostly a dull black, contrasting quite strongly with the yellow of the anthers and pollinia and the white style-head. It consists of short outer lobes and inner lobes which just cover the anthers. From: Bruyns, PV. 2005. Stapeliads of southern Africa and Madagascar, Vol. 2. Umdaus Press, Hatfield.

Quaqua pruinosa is always a plant of gravelly to stony terrain and specimens usually grow inside a shrub, sometimes outgrowing it and projecting beyond it into the open. Plants are usually not particularly common. From: Bruyns, PV. 2005. Stapeliads of southern Africa and Madagascar, Vol. 2. Umdaus Press, Hatfield.

Quaqua pruinosa is widely distributed in Namaqualand east of the sandveld, mainly in the hills below the escarpment, on the slopes of the escarpment itself and, more rarely, on its eastern flank. It has been recorded from near Wallekraal in the south-west and Kamieskroon in the south-east northwards into Namibia to Rosh Pinah in the north-west and near the Gamkab River in the north-east.
