Definition

Proper noun 1. Rhoeadales: An order of dicotyledonous flowering plants. This taxonomic order historically included families characterized by having flowers with numerous stamens and a superior ovary. Modern botanical classification has largely superseded this order, with its former families now distributed within other orders, notably the Ranunculales and Brassicales.
