Fagales

In the modern world, Fagales has become a topic of increasing importance and relevance. Whether in the field of technology, health, politics or culture, Fagales has captured the attention of experts, researchers and the general public. The impact of Fagales has been felt in multiple aspects of daily life, generating debate, controversy and significant advances in various fields. In this article, we will explore the influence of Fagales on society today and its possible implications for the future.

The Fagales are an order of flowering plants, including some of the best-known trees. The order name is derived from genus Fagus, beeches. They belong among the rosid group of dicotyledons. The families and genera currently included are as follows:

The older Cronquist system only included four families (Betulaceae, Corylaceae, Fagaceae, Ticodendraceae; Corylaceae now being included within Betulaceae); this arrangement is followed by, for example, the World Checklist of selected plant families.[2] The other families 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 Balanops). The change is due to studies suggesting the Myricales, so defined, are paraphyletic to the other two groups.

Characteristics

Most Fagales are wind pollinated and are monoecious with unisexual flowers.[3]

Evolutionary history

The oldest member of the order is the flower Soepadmoa cupulata preserved in the late Turonian-Coniacian New Jersey amber, which is a mosaic with characteristics characteristic of both Nothofagus and other Fagales, suggesting that the ancestor of all Fagales was Nothofagus-like.[3]

Systematics

Modern molecular phylogenetics suggest the following relationships:[1][citation needed]
