NOTES: Genetic polymorphism in hickory hybrids is common, resulting in phenotypic variation. In the photographed specimen, this three-trunked tree growing on a dry ridge appears to be a Shagbark-Bitternut Hickory hybrid. While the shaggy bark and compound leaves with five leaflets suggest Shagbark Hickory, the nuts have thin, teardrop-shaped husks with prominent ridges, more closely resembling the smaller, round-husked nuts of Bitternut Hickory. Interestingly, unlike a nearby Bitternut Hickory, most nuts under this tree had been eaten by wildlife, suggesting that these hybridized nuts are more palatable.
