Hickory (Carya spp.) is composed of at least 16 species native to Asia , Central America  and North America ). The word carya is from the Greek name for nut. This group can be split into the true hickories and the pecans.
Pecan hickories usually have more and narrower leaflets and are generally shorter lived than the true hickories.
Most hickories have edible nuts and the Pecan is grown commercially. Hickory wood tends to be strong and resilient and is often used to flavor meat in smoking or barbecuing.
