Ceraria is a genus of succulent shrubs, native to South Africa and Namibia.

Taxonomy

Recent phylogenetic tests have shown conclusively that Ceraria is located within the genus Portulacaria, and consequently all species have been accordingly renamed.[1]

Description

They are very slow-growing, semi-deciduous or deciduous, and succulent perennials with a few branches and many small, ovoid leaves along the stems. Branches are pale-barked smooth with papery cortex. These woody-stemmed desert shrubs have many short and ovoid gray-green leaves. Flowers, born on peduncles of 13–17 mm long, with some minute ovate bracts 4 mm long. Calyx with two phyllous, 5 rose-colored, obovate, 2 mm long petals. Five stamens with linear filaments.
