The Anacampserotaceae is a family of succulent plants under the Portulacineae subgroup. Species can be found in South African regions. The family was described by Urs Eggli and Reto Nyffeler in their analysis of the polyphyly in the suborder Portulacineae (order Caryophyllales). Genetic research led to the discovery of the ACPT clade where the Anacampserotaceae family is placed. Species can interchangeably switch photosynthetic pathways based on environmental water stress. The three recognized genera - Anacampseros, Grahamia, and Talinopsis - were formerly placed in the Portulacaceae. This family was accepted in the Angiosperm Phylogeny Group's 2009 publication of the APG III system.
