Leaves | 3-6 dm; petiole 4-13 cm, petiole and rachis hirsute or mainly glabrous. |
Leaflets | (3-)5(-7), lateral petiolules 0-1 mm, terminal petiolules 3-17 mm; blades ovate, obovate, or elliptic, not falcate, 4-26 × 1-14 cm, margins finely to coarsely serrate, with tufts of hairs in axils of proximal veins of serrations, often weathering to only a few in fall, apex acute to acuminate; surfaces abaxially hirsute with unicellular and 2-4-rayed fasciculate hairs, occasionally restricted to midrib and major veins or essentially without hairs, with few to many large peltate scales and small round, irregular, and 4-lobed peltate scales. |
Fruits | brown to reddish brown, spheric to depressed-spheric, not compressed, 2.5-4 × 2.5-4 cm; husks rough, 4-15 mm thick, dehiscing to base, sutures smooth; nuts tan, ovoid, obovoid, or ellipsoid, compressed, 4-angled, rugulose; shells thick. |

Discussion | Carya ovata hybridizes with C. cordiformis (C. ×laneyi Sargent), C. illinoinensis, and C. laciniosa (C. ×dunbarii Sargent). The Mexican shagbark appears to be a good variety. The Mexican hickory (Carya ovata var. mexicana (Hemsley) W. E. Manning) appears to be synonymous with C. ovata. Native Americans used Carya ovata medicinally as an antirheumatic, a gynecological aid, a tonic, and an anthelmintic (D. E. Moerman 1986). Varieties 3 (2 in the flora).
