Anacampserotaceae

Anacampserotaceae is a small family of flowering plants in the order Caryophyllales. It comprises three genera of succulents: Anacampseros, Avonia, and Grahamia. The family was recognized in modern classifications based on molecular phylogenetic studies, and is treated as distinct from related groups such as Portulacaceae in systems like APG IV.

Plants in this family are typically small to medium-sized perennials adapted to arid environments. They are commonly found as cushion-forming mats or low, creeping clumps. Like many succulents, they store water in fleshy leaves and stems. Leaf arrangement varies, but many species have thick, fleshy leaves that may be opposite or arranged in rosettes, with surfaces that can be smooth, hairy, or glandular. The inflorescences bear relatively small flowers, usually solitary, with five or more petals, and colors ranging from white to pink or purple. The fruits are generally dry capsules containing small seeds.

Distribution for Anacampserotaceae centers on southern Africa, particularly in arid regions such as the Karoo and surrounding areas, with some species extending into neighboring climates. They are cultivated by succulent enthusiasts for their compact growth and distinctive textures, requiring bright light and well-draining soil. In cultivation, watering should be infrequent and allow the soil to dry between waterings, with protection from frost in temperate regions. Propagation is commonly achieved by seed or through vegetative cuttings.

Taxonomic notes: The concept of Anacampserotaceae has varied over time, with some genera previously placed in Portulacaceae or other related families. Contemporary classifications consistently recognize Anacampserotaceae as a distinct family within Caryophyllales.
