The family '''Fagaceae''', or '''beech family''', is characterized by alternate [[leaf|leaves]] with pinnate venation, [[flower]]s in the form of [[catkin]]s, and [[fruit]] in the form of [[Nut (fruit)|nuts]], one to seven in a scale or spiny husk that may or may not enclose the nut. The best-known group of this family is the [[oak]]s, genus ''Quercus'', the fruit of which is called an [[acorn]]. The husk of the acorn in most oaks only forms a cup in which the nut sits.
==Genera==
*''[[chestnut|Castanea]]'' - Chestnuts; eight species, north temperate east Asia, southwest Asia, southeast Europe, eastern North America
*''[[Castanopsis]]'' - about 125-130 species, southeast [[Asia]]
*''[[Chrysolepis]]'' - Golden chinkapin; two species, western [[United States|USA]]
*''[[Colombobalanus]]'' - one species ''C. excelsa'', northern South America, often included in ''Trigonobalanus''
*''[[Cyclobalanopsis]]'' - about 150 species, southeast [[Asia]]
*''[[beech|Fagus]]'' - Beeches; 10 species, north temperate east Asia, southwest Asia, Europe, eastern North America
*''[[Formanodendron]]'' - one species ''F. doichangensis'', southeast Asia, often included in ''Trigonobalanus''
*''[[Lithocarpus]]'' - Tanoaks or Stone oaks; about 330-340 species, all but one in warm temperate to tropical Asia, the one (''L. densiflorus'') in [[California]] and southwest [[Oregon]]
*''[[oak|Quercus]]'' - Oaks; about 500 species, widespread [[Northern Hemisphere]], crossing the [[equator]] in [[Indonesia]]
*''[[Trigonobalanus]]'' - one species ''T. verticillata'', tropical southeast [[Asia]] (three species if ''Colombobalanus'' and ''Formanodendron'' included)
The genus ''[[Nothofagus]]'' (Southern beeches; about 35 species from the Southern Hemisphere), formerly included in the Fagaceae, is now treated in the separate family [[Nothofagaceae]].
