Trees in the genus Carya (from Ancient Greek êÜñõïí "nut") are commonly known as hickory. The hickory genus includes 17–19 species of deciduous trees with pinnately compound leaves and large nuts. A dozen or so species are native to North America (11–12 in the United States, 1 in Mexico), and 5–6 species from China and Indochina. The hickory tree, along with the oaks truly dominates the hardwood forests of North America.
