  4. Introduce of Fagaceae Family  The Fagaceae Familyor beech family includes 9 genera and ca. 1000 species of both evergreen and deciduous trees and shrubs.  Fagaceaedominates in forests of tropical, temperate and cold temperate regions of the Northern Hemisphere.  The members of Fagaceae Family are characterized by alternate simple leaves with pinnate venation, unisexual flowers in the form of catkins and fruit in the form of cup-like (cupule) nuts.

  5. The distribution pattern of Fagaceae Atpresent, there are two distribution centers of the floristic region: 1-Southern east Asia to northern southeast Asia (the main distribution) 2-SouthernMadrean to Caribbean region (Southwest USA, Mexico, Central America )

  6. The distribution pattern of Genera The genera of Fagaceae are divided into four disjunctive distribution patterns: 1- The genus that distributes between tropicalAsiaregions and tropical central America: Trigonobalanus. 2- The genus that distributes between Asia and west of North America: Lithocarpus, Castanopsis & Chrysolepis. 3- The genus that distributes between Eurasia and North America: Castanea, Fagus. 4- The genus that distribute between Eurasia, North Africa and America: Quercus,Colombobalanus & Formanodendron.

  7. Introduce of FagaceaeGenera The Fagaceae genera including: 1- TrigonobalanusForman. 2-LithocarpusBl. 3-Castanopsis Spach. 4-Castanea L. 5-Fagus L. 6-Quercus L. 7- ChrysolepisHjelmquist. 8-Colombobalanus (Lozano, Hdz-C. & Henao) Nixon & Crepet. 9-FormanodendronNixon & Crepet.

  8. Quercus  Quercus (oak)is a tree or shrub with about 600 species exists on earth. The genus is native to the Northern Hemisphereand includes deciduous and evergreen species extending from cold latitudes to tropical Asia and the America.  Oaks have leaveswith a lobed margin in many species; some have serrated leaves or entire leaves with a smooth margin. The flowers are catkins. The fruit is a called an acorn, borne in a cup-like structure known as a cupule.

  9. Quercus The genus Quercus (oak) divided into two sub genus and several sections:  SubgenusQuercus Section Quercus  White oaks live oaks Section Lobatae Red oaks Section Mesobalanus Section Cerris Section Protobalanus (Intermediate oaks)  Subgenus Cyclobalanopsis (The ring-cupped oaks)
