Terminal buds sulfur yellow to tan, oblong, 10(-19) mm, densely scaly with yellow peltate scales, pilose near apex; bud scales valvate; axillary buds protected by pair of valvate bracteoles. Leaves 2-4 dm; petiole 3-7 cm, glabrous near base, hirsute near rachis. Leaflets (5-)7-9(-13), lateral petiolules 0-1 mm, terminal petiolules 2-8 mm; blades ovate-lanceolate, rarely falcate, 3-19 × 1-7 cm, margins finely to coarsely serrate, without tufts of hairs, apex acuminate; surfaces abaxially villous with unicellular and 2-4-rayed fasciculate hairs along midrib and major veins, densely to sparsely pubescent throughout, and with abundant large peltate scales and small round and 2- or 4-lobed peltate scales in spring, still present near margins at base and apex in fall, adaxially villous along midrib near base, sparsely scaly in spring. Staminate catkins pedunculate, to 16 cm, stalks without hairs or hirsute, bracts scaly; anthers hirsute. Fruits brown, cylindric, obovoid, or nearly spheric, not compressed or only slightly compressed, 2-3 × 2-3.2 cm; husks rough, 2-3 mm thick, dehiscing to middle or slightly below, sutures winged; nuts light brown, ellipsoid to ovoid, not compressed or only slightly compressed, not angled, rugulose; shells thin.

Discussion
Carya cordiformis hybridizes with C. illinoinensis (C. ×brownii Sargent), C. ovata (C. ×laneyi Sargent), and C. laciniosa, and reputedly with the tetraploid C. glabra (C. ×demareei Palmer).
The Fox Indians used Carya cordiformis medicinally as a diuretic, a laxative, and a panacea (D. E. Moerman 1986).
