Birch is the name of any tree of the genus Betula, in the family Betulaceae, closely related to the beech/oak family, Fagaceae. Birch species are generally small to medium-size trees or shrubs, mostly of northern temperate climates. The simple leaves may be toothed or pointed and the fruit is a small samara. The bark of all birches is characteristically marked with long horizontal lenticels, and often separates into thin papery plates, especially the Paper Birch.
