Taxonomy
The Rubiaceae is the first branch in the Gentianales in the Apg3 classification. In the past it was often put in its own order Rubiales. Rubiaceae is split in 3 subfamilies: Rubioideae, Cinchonoideae and Ixoroideae. Rubiaceae is quite big with about 600 genera and 6000 species. In contrast only 3 species are well known in homeopathy: China, Coffea and Ipecacuanha.
In the Plant theory Rubiaceae is split off from the Order Gentianales and put in its own Order Rubiales. Rubiaceae is quite different form Gentianales. They are much more sure, fitting Phase 4, instead of the Phase 2 quality of Gentianales. The splitting does not affect the monophyly of both Orders.
Oleaceae is placed in Rubiales as its theme is very similar to Phase 4. Oleaceae has been associated with Gentianales and Rubiales more often in the past by botanist like Bessey, Meechior and Reveal.
Rubiaceae is is split in its 3 Subfamilies and Coptosapelteae. Coptosapelteae is an unclear Subfamily in Apg3 is placed in Subphase 3.
This Order Rubuiales gives rise to some problems in its classification. This is especially the case while Rubiaceae are little known in homeopathy and on the other hand Rubiaceae is a very big Family.
