Genera 4, species ca. 78 (1 genus, 8 species in the flora). Tamaricaceae have traditionally been placed in the Violales, but recent analyses of molecular sequence data place the family within the Caryophyllales of the core eudicots. Frankeniaceae has retained its place as sister family to Tamaricaceae, sharing similarities in many characters, including secondary chemistry and salt gland structure.
