Interpretive Summary: This is a description of the pecan that was prepared for the Encyclopedia of Fruit and Nuts. People who do not know what a pecan tree is can learn that it is an important nut-producing tree that grows naturally in the forests of North America. Most of the pecan nuts produced in the world come from the United States, but other countries also grow some. How the nuts are used and their food value is described. The nuts, leaves and trees are described to help someone identify the plant. Some of the first descriptions of pecans were made by people who called the trees by different names, and some of the important name changes are described. Information is given about where trees can be found growning naturally, and how they are grown in commercial orchards.
