The Butternut tree is in the same family as the Walnut tree, the Juglan family. The Butternut tree has compound, alternate leaves, that have 11 - 17 or so leaflets. There is an end leaflet on each leaf and the underside of these leaflets are fuzzy. The oily, delicious nuts are an important food source for many small mammals.
