The Buxales are a small order of eudicot flowering plants, recognized by the APG III system of 2009. The order includes the family Buxaceae; the families Didymelaceae and Haptanthaceae may also be recognized or may be included in the Buxaceae. Many members of the order are evergreen shrubs or trees, although some are herbaceous perennials. They have separate "male" (staminate) and "female" (carpellate) flowers, mostly on the same plant (i.e. they are mostly monoecious). Some species are of economic importance either for the wood they produce or as ornamental plants.
