a genus of plants of the family Juglandaceae. They are monoecious deciduous trees with large odd-pinnate leaves. The flowers are in the axils of the bracts. The staminate flowers are in drooping multiflorous catkins; the pistillate flowers are in few-flowered apical inflorescences. The fruit is a drupe with a green fleshy husk and a hard, woody inner shell. The edible seed does not have an endosperm. There are 14 or 15 species of Juglans (according to other data, up to 40), growing in mixed broad-leaved forests, predominantly in the mountains of Southern Europe, Asia, and America. Many species have been raised since ancient times for their nutritious and tasty fruits and for their beautiful, valuable wood. They have also been cultivated as ornamentals for a long time. In the USSR two species grow wild: the English walnut and the Manchurian walnut. Six species have been introduced into the USSR.
