Interpretive Summary: This chapter is part of a book describing how to grow nut trees. The chapter on hickories gives information that will help people identify the different types of hickories and understand more about where they grow and the types of nuts they produce. There is information about the origin of these trees from the earliest fossil records, as well as information about the historic use of the trees by Native Americans and early settlers. Trees that bear large nuts are often grafted to other rootstocks. Names are given to these special trees, called "cultivars" because they are "cultivated varieties" of the species. The names of important hickory cultivars are given to help growers choose trees to plant in their area. In addition to the written information, there is much information provided in distribution maps and pictures of the nuts, buds, leaves and bark of the different types of hickory. Hickory trees live for a long time, and people who plant them often study them over many years. This chapter is intended to help people find answers to some of the questions they may have about their trees, as well as to provide references to other books and articles where more information is available.

Technical Abstract: This chapter is a detailed description of species in the genus Carya. It provides information on the evolutionary history, taxonomy, nomenclature and economic botany of the genus. Thirteen species are described in detail, with distribution maps and photographs of diagnostic characteristics. The chapter should serve as a practical and informative reference for students of this important group of native North American trees.
