Definition
A 'bitter pignut' refers to a variety of pignut hickory whose nuts are particularly bitter and unpalatable. Pignut hickories themselves vary in taste, but a 'bitter pignut' indicates a distinctly unpleasant flavor. These nuts are typically avoided by humans but can still serve as a food source for wildlife. The name highlights a key characteristic: the strong, bitter taste that distinguishes it from other, more edible nuts. This makes it less desirable for human consumption.
