Taxonomy
In the Cronquist system Geraniaceae was placed in Oxalidales together with Oxalidaceae, Limnanthaceae, Tropaeolaceae and Balsaminaceae. In the Apg2 classification Geraniales was placed in Rosidae, outside Eurosidae 1 and 2. In the Apg3 classification Geraniales has been connected with the Myrtales and seen as sister to Malvidae, or combined with the Malvidae in an extended Malvidae.
The demarcation of the families is still in dispute. Geraniaceae is the main family, the other families are very small.
In the Plant theory they are the third Subclass of Malvanae, with the emphasis on the Silicon series. Only members of Geraniaceae are known in homeopathy. The division into Subphases is done tentatively on taxonomic data.
Geraniacaeae and Melianthaceae will be further discussed.
