The genus Juglans, which includes various species of Butternuts and Walnuts, was named by the Swedish botanist, Carl Linnaeus, who developed the modern classification system for plants and animals. He evidently thought well of them, because “Juglans” is the nut of the gods, a combination of Jovis (the god Jupiter) and glans, an acorn or nut. The native Butternut (Juglans cinerea) was never common, and it’s easily overlooked due to the similarity to Black Walnut (J. nigra).
