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.
Myricaceae Myricaceae is a small family of dicotyledonous shrubs and small trees in the orderFagales.
The Fagales are an order of flowering plantsflowering plants (also angiosperms or Magnoliophyta) are one of the major groups of modern plants, comprising those that produce seeds in specialized reproductive organs called flowers, where the ovulary or carpel is enclosed.
Intercellular penetration of the root epidermis may be the plesiomorphic route of infection, occuring in both Rosales and Cucurbitales; in Fagales infection is by root hairs (Clawson et al.
The leaf teeth in Juglandaceae, Rhoipteleaceae and Myricaceae are intermediate in "type", having a ± splayed, (non)glandular apex, and the main tooth vein is joined by branches that leave below, or one of the branches may proceed above the tooth (Hickey and Taylor 1991).
Fagales are the core of the old "Englerian" Amentiferae which have since been demolished, members finding resting places among many otherwise entirely unrelated groups within the Eudicots such as Saxifragales, Malpighiales, Proteales, and Rosales (Qiu et al.
