水青冈属

水青冈属（Fagus）植物是北温带落叶阔叶林的主要树种，该属共有11种。中国5种均为特有种。

There are 11 species in Fagus , 5 of them are endemic to China . They are the major trees of deciduous broadleaved forest in Northern temperate region .

主要是雌雄同株乔木和灌木；山毛榉树；栗子；橡树；板栗属；锥栗属；水青冈属；石栎属。

Chiefly monoecious trees and shrubs : beeches ; chestnuts ; oaks ; genera Castanea ; Castanopsis ; Chrysolepis ; Fagus ; Lithocarpus ; Nothofagus ; Quercus .

本文的水青冈属的分子系统发育和泛生物地理学研究的结果是一致的，都说明水青冈属植物在物种形成和演化的过程中，受到大陆漂移等地质历史事件的影响。

The results of the study of molecular phylogeny is consistent with the Panbiogeography result . This indicates that the process of formation and evolution of Fagus genus were affected by the continental drift and the geological history events .
