Hickory is a tree of the genus Carya (which also includes Pecan). The genus includes 17-19 species of deciduous trees with pinnately compound leaves and large nuts. Of the 17-19 species, 12-13 are native to North America (11-12 in the United States, 1 in Mexico), and 5-6 species from China and Indochina. Another Asian species, Beaked Hickory, previously listed as Carya sinensis, is now treated in a separate genus as Annamocarya sinensis.

Hickory flowers are anemophilous and self incompatible, so two clonal (grafted) trees cannot pollenize each other. Two or more varieties must be planted for pollination. Seedlings (grown from hickory nuts) will usually have sufficient genetic variation.
Uses
Hickory wood is extremely tough, yet flexible, and is valuable for tool handles, bows, etc. It is also highly prized for woodburning stoves, because of its high caloric content. Hickory wood is also a preferred type for smoke curing meats. The nuts of some species are palatable; while others are bitter, and only suitable for animal feed. Shagbark and Shellbark Hickories are regarded by some as the finest nut trees. A bark extract from Shagbark Hickory is also used in an edible syrup that is similar to maple syrup, with a slightly bitter, smoky taste.
