Definition
A 'pignut hickory' is a species of hickory tree native to eastern North America, known for producing nuts that are somewhat edible but often bitter. These trees are characterized by their smooth bark and relatively small nuts. The name 'pignut' comes from the historical use of these nuts as food for pigs. While humans can eat them, they are not as palatable as pecans or other hickory nuts. Overall, the pignut hickory is a common but not particularly prized hickory tree.
