any of about 20 species of deciduous trees constituting the genus Juglans of the family Juglandaceae, native to North and South America, southern Europe, Asia, and the West Indies. The trees have long leaves with 5 to 23 short-stalked leaflets; male and female reproductive organs are borne in different, petalless flower clusters on the same tree; the twigs contain a many-chambered pith; and the fruit is a woody nut enclosed in a thick husk. Black walnut (J. nigra) of eastern North America and English, or Persian, walnut (J. regia), native to Iran, are valuable timber trees that produce edible nuts.
