there remains substantial uncertainty regarding the relationships within Francoaceae sensu stricto (s.s.), Melianthaceae (Bersama Fresen. and Melianthus L.) and Ledocarpaceae. Here, Vivianiaceae is used as a later synonym for Ledocarpaceae. This due to conflicting evidence (see Palazzesi et al., 2012). The APG chose to follow the broader circumscription for the time being till these differences are resolved. This leaves the order Geraniales with only two families: Geraniaceae and Francoaceae (including Bersamaceae, Greyiaceae, Ledocarpaceae, Melianthaceae, Rhynchothecaceae and Vivianiaceae). The Vivianiaceae and Ledocarpaceae were included within the Geraniaceae, and the Hypseocharitaceae within the Oxalidaceae, which are now treated in the order Oxalidales. The Melianthaceae were placed within the Sapindales, the Greyiaceae and Francoaceae within the Rosales, the latter subsumed within the Saxifragaceae. Recent comparison of DNA-fragments from species within the order resulted in the following phylogenetic tree.
