Juglandaceae
The Juglandaceae, also known as the walnut family, is a family of trees, or sometimes shrubs, in the order Fagales. Various members of this family are native to the Americas, Eurasia, and Southeast Asia. Members of the walnut family have large, aromatic leaves that are usually alternate, but opposite in Alfaroa and Oreomunnia. The leaves are pinnately compound, or ternate, and usually 20–100 cm long.
The trees are wind-pollinated, and the flowers are usually arranged in catkins.
The eight genera in the family include the commercially important nut-producing trees walnut (Juglans), pecan (Carya illinoinensis), and hickory (Carya). The Persian walnut, Juglans regia, is one of the major nut crops of the world. Walnut, hickory, and gaulin are also valuable timber trees.
