Its distribution closely mirrors that of related genus Tromotriche. In distribution, the genus Quaqua is restricted to the western (winter-rainfall) region of South Africa & Namibia. The flowers of other species however, are larger, reaching a maximum diameter of 27 mm and are dark, papillate, and usually have a repulsive odor of urine or excrement. The flowers of some species are sweet smelling (faintly of honey or lemon), attractive and rather small (between 7 and 15 mm in diameter). There are often ten along each stem, vertically arranged in distichous series.
Quaqua flowers are distinctive from those of other southern African stapeliads for their numerous inflorescences emerging from each stem, especially closer to the ends. A few species lack the spikes or have smoothly rounded tubercles. 8 0.125 0 0.018 0 0 1.0000 ReDIF-book Coleccin La hora de la Igualdad.
Species of Quaqua are usually characterised by having stout, firm, 4 or 5-sided stems bearing conical tubercles which often have a tough, tapering spike at their ends. Quaqua ramosa, from the western Karoo, locally called "Ou Ram" ("old ram"), is unusual in having rounded tubercles instead of the typical quaqua spikes
