Crassula alba is a species of flowering plant in the genus Crassula found in western Africa ranging from South Africa to Sudan.
Crassula alba is in the genus Crassula , family Crassulaceae and order Saxifragales. There are two accepted infraspecies, Crassula alba var. pallida and Crassula alba var. parvisepala.
The Crassulaceae, also known as the stonecrop family or the orpine family, are a diverse family of dicotyledon flowering plants characterized by succulent leaves and a form of photosynthesis, known as Crassulacean acid metabolism (CAM). Flowers generally have five floral parts. Crassulaceae are usually herbaceous but there are some subshrubs, and relatively few treelike or aquatic plants. Crassulaceae are a medium-sized monophyletic family in the core eudicots, among the order Saxifragales, whose diversity has made infrafamilial classification very difficult. The family includes approximately 1,400 species and 34–35 genera, depending on the circumscription of the genus Sedum, and distributed over three subfamilies. Members of the Crassulaceae are found worldwide, but mostly in the Northern Hemisphere and southern Africa, typically in dry and/or cold areas where water may be scarce, although a few are aquatic.
Crassula is a genus of succulent plants containing about 200 accepted species, including the popular jade plant.
