Frankeniaceae, Dict. Rais. Bot.: 188. 1817 sec. APG III (2009)
- Type: Frankenia
A monogeneric family with 70-80 species of halophytic and xerophytic shrubs, subshrubs and herbs (Whalen 1987; Kubitzki 2003d) distributed throughout the warmer dry regions of the world (Kubitzki 2003d). Kubitzki (2003d) recognized two genera: Frankenia and the monospecific Hypericopsis; however in the same year Olson & al. (2003) supported the inclusion of Hypericopsis within Frankenia based on wood anatomical characters. The position of Hypericopsis within the Eurasian and Australian clade of Frankenia has also been well-supported by the molecular phylogenetic study of Gaskin & al. (2004).
