Definition
Proper noun 1. A taxonomic order of flowering plants: Primulales is an order of dicotyledonous plants, primarily herbaceous, within the class Magnoliopsida. This order historically included families such as Primulaceae (primroses), Theophrastaceae, Myrsinaceae, and sometimes Plumbaginaceae (leadworts). In modern taxonomic systems (e.g., APG IV), this order is not recognized, and its constituent families are placed within the order Ericales.
