Leaf: Alternate, pinnately compound with 5 to 9 (usually 7 leaflets), 15 to 24 inches long, each leaflet obovate to lanceolate, dark-green above, paler and tomentose below. The rachis is stout and may be tomentose.  
Flower: Monoecious; males are 2 to 3 inches long, yellow-green catkins; females are short, in clusters at the end of the branches, appearing in mid-spring.  
Fruit: Round, 2 to 2 1/2 inches long, extremely thick husk (up to 1/2 inch), nut is 4-ribbed (maybe 6), maturing in early fall.  
Twig: Stout, yellowish brown, usually glabrous, numerous lenticels, leaf scar three-lobed; terminal bud elongated (larger than shagbark) with numerous persistent, brown scales.  
Bark: Initially smooth and gray with shallow interlacing ridges, later developing long, loose plates, resulting in a shaggy appearance.  
Form: A large tree 80 to 100 feet tall, with a straight trunk and a narrow crown.  
Interesting Facts: Shellbark hickory is a slow-growing long-lived tree, hard to transplant because of its long taproot, and subject to insect damage. The nuts, largest of all hickory nuts, are sweet and edible. Wildlife and people harvest most of them; those remaining produce seedling trees readily. The wood is hard, heavy, strong, and very flexible, making it a favored wood for tool handles.
