Genus of hardy, deciduous trees of the family Betulaceae, common to North America, Europe and Asia. Birch tress are readily distinguished by their white bark and diamond-shaped leaves. The lightweight bark contains natural waxes, oils, and tannins that make it tough, durable, and waterproof. Thin sheets of bark were commonly used for paper in Central Asia and the Far East. The water-impervious bark was used for wigwams, canoes, and shoes for Native Americans. Birch produces a strong, pale yellow-brown wood with a close, straight grain and uniform texture that finishes to a smooth surface. Dyes can also be obtained from various parts of birch trees. The leaves, usually gathered before they develop a mature green color, produce a yellow dye. The bark produces a pale brown color. The female catkins (a long shoot bearing flowers with no leaves) are boiled to produce a dull yellow color. Birch bark oil and birch beer are made from sap obtained from the trees. The sap allows birch bark to burn even when it is wet.

Species of birch tree abundant throughout northern Europe, Iceland, northern Asia, and Greenland. It is a deciduous tree growing to over 60 feet tall (18 m), with a slender crown and a trunk, having smooth dull gray-white bark finely marked with dark horizontal lenticels. It is closely related to, and often confused with the silver birch.

Species of birch tree native to the Himalayas, growing at elevations up to 4,500 m (14,800 feet).

Betulaceae is the birch family of flowering plants, usually placed in the order Fagales; some authorities, however, have placed the family in the order Betulales. The family contains six genera and 120-150 species. Although not done in this hierarchy, it is elsewhere sometimes divided into two subfamilies: Betuloideae, with the genera Betula (birch) and Alnus (alder); and Coryloideae, with the genera Carpinus (hornbeam), Corylus (hazel, or filbert), Ostrya, and Ostryopsis.
