Scope note
Species of large, deciduous tree native to the Himalayas, Iran, Lebanon, Asia Minor, and Greece, and growing in Britain and elsewhere since about the middle of the 15th century. It reaches heights to 35 meters with a trunk up to 2 meters in diameter. It has a short trunk and broad crown, though taller and narrower in dense forest competition; it thrives in full sun. It is a valuable timber tree; other portions of the tree also have commercial value. The nut kernels are used for cooking and the pale yellow fast-drying oil expressed from the nuts is used for artists' paints. Tannins and dyes are extracted from the nut hulls and shells that produce a brown color. Ground nut shells have been used as a soft abrasive and a plastic filler.
