In the Apg3 classification the families Primulales are included in a broad Order Ericales. That Order is a combination of formerly separate Orders like Theales, Ericales, Primulales, Ebenales. Primulaceae, Myrsinaceae and Theophrastaceae form a monophyletic clade in Ericales. Maesaceae and Theophrastaceae are recognised Families in the Primulales clade. Primulaceae is split in Primulaceae and Myrsinaceae.
In the Plant theory Ericales is upgraded to the level of Subclass Ericidae. Primulales is treated as an Order in Ericidae. Primulales is placed in Phase 3. The placement in Subphases is tentative, as only Primulaceae and Myrsinaceae are known in homeopathy.
Maybe Primulaceae has to be split further in Families.
