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", "Oreomunnia". The leaves are pinnately compound, or ternate, and usually 20-100 cm long.

The trees are wind-pollinated, the flowers usually arranged in catkins, and the fruit is a true botanical nut.

There are eight genera in the family, including 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 and hickory are also valuable timber trees.

Tryma

Some fruits are borderline and difficult to categorize. Hickory nuts (Carya) and Walnuts (Juglans) in the Juglandaceae family grow within an outer husk; these fruits are technically drupes or drupaceous nuts, and thus not true botanical nuts. "Tryma" is a specialized term for such nut-like drupes. [http://waynesword.palomar.edu/fruitid1.htm Identification Of Major Fruit Types] [http://waynesword.palomar.edu/ecoph8.htm Fruits Called Nuts]
