HICKORY

Hickory is several species of timber trees of the genus Carya of the family Juglandeae. They are natives to North America. The wood is heavy, strong and tenacious and was used for making carriage-shafts, screws, whip-handles, cogged wheels, etc. The shag-bark (Carya alba) yields the hickory-nut of commerce, and its wood is very valuable. Carya olivoeformis yields the pecan-nut. The pig-nut or brown hickory is the Carya glabra, and the swamp hickory is Carya amara, so called from the bitterness of its nut.
