The Fagales are an order of flowering plants, including some of the best known trees. They belong among the rosid group of dicotyledons. Families typically included here are listed at right, though the Kew checklist (see external link below) only includes the first four families listed.
In the older Cronquist system, these plants were split into three different orders, placed among the Hamamelidae. The Casuarinales comprised the single family Casuarinaceae, the Juglandales comprised the Juglandaceae and Rhoipteleaceae, and the Myricales comprised the remaining forms (plus Belanops). The change is due to studies suggesting that the Myricales, so defined, are paraphyletic to the other two groups.
