Introduction

A family with three genera and around 36 species mainly distributed in the southern and eastern parts of Africa, but also found in North America, South America, and Australia (Nyffeler & Eggli 2010). The species of this family are traditionally considered members of Portulacaceae; however, molecular phylogenetic studies have shown that the traditional Portulacaceae are not monophyletic (Hershkovitz & Zimmer 1997; Applequist & Wallace 2001; Nyffeler 2007; Nyffeler & Eggli 2010; Ocampo & Columbus 2010). Nyffeler & Eggli (2010) proposed the segregation of the traditional Portulacaceae into four families (Anacampserotaceae, Montiaceae, Portulacaceae, and Talinaceae) based on morphological and molecular data. In this context, the Anacampserotaceae are recognized by their capsules with loculicidal dehiscence whose endocarp valves form a basket-like structure and by their seeds whose testa layers separate from each other (Nyffeler & Eggli 2010).A,B,C,D,E

Distribution (General)

Southern and eastern Africa, Australia, Argentina, Bolivia, Mexico, United States.D
