Genus comprised of around 7 succulent, small tree, shrub or subshrub species with a low number of waxy branches. This genus is termed dioecious and thus produces male and female flowers on individual plants, however some species produce bisexual flowers, which contain both male and female reproductive structures. Foliage is produced in pairs or grouped clusters and the leaves are flattened, oval-shaped, grey-green and tapered at the tips. Flowers are small with 5 petals measuring around 0.2cm in length, these are produced in groups of 1-6 and coloured white to pink. This genus is commonly found in South Africa and Namibia.
