Juglandaceae

Juglandaceae, commonly known as the walnut family, is a group of trees and shrubs that includes walnuts and hickories. This family, part of the order Fagales, is primarily found in the Northern Hemisphere but extends into Central and South America.1

Key characteristics of Juglandaceae include:
* Leaves: Typically odd-pinnate compound leaves, which is unusual within the Fagales order. These leaves are often aromatic.23
* Flowers: Unisexual flowers, usually wind-pollinated, with staminate flowers often in catkins and pistillate flowers in clusters.32
* Fruit: A drupe with a fibrous outer layer and a hard, nut-like inner shell. The fruit is often surrounded by a hull or cupule.32

The wood from these trees is known for its grain patterns and luster. The family contains about 50 species across 7 to 10 genera.21
