Distribution. Hillsides and dry ridges; southwestern Vermont to western New York, southeastern Ontario, southern Indiana and southwestern Illinois, and southward to Delaware, the District of Columbia and eastern Virginia, and along the Appalachian Mountains to North Carolina; in northern, central and eastern Georgia, northern Alabama and eastern Mississippi. The name “Pignut” usually applied to this tree and to the forms of _C. ovalis_ Sarg., especially in the north, properly belongs to _C. cordiformis_ Schn. Passing into Carya glabra var. megacarpa Sarg. _Carya megacarpa_ Sarg. [Illustration: Fig. 182] Leaves 12′—14′ long, with slender glabrous petioles and 5—7 lanceolate to oblanceolate leaflets long-pointed and acuminate at apex, gradually narrowed and unsymmetrical at base, finely serrate, glabrous or very rarely pubescent, often furnished below with small clusters of axillary hairs, the three upper 8′—10′ long and 1½′—2½′ wide and about twice as large as those of the lowest pair. Flowers: staminate in slightly villose aments 2½′—3′ in length, villose, their bract long-pointed, acuminate, villose, twice longer than the calyx-lobes, stamens 4—6, anthers yellow, villose above the middle; pistillate in short-stalked spikes, their involucre only slightly angled, covered with pale yellow hairs, the bract acuminate, twice longer than the bractlets and calyx-lobes. Fruit oblong-obovoid with a stipe-like base to short-obovate and rounded or abruptly cuneate at base, rarely depressed at apex, slightly flattened, often covered with bright yellow scales, 1′—2′ long, 1′—1½′ in diameter, with a husk ⅛′—⅕′ in thickness, opening tardily to the middle usually by one or by two sutures, or often remaining closed; nut broadest toward the rounded apex or oblong and occasionally acute at apex, gradually narrowed and acute at base, often compressed, slightly or rarely prominently angled (f. _angulata_ Sarg.), with a shell ⅛′—⅙′ in thickness; seed small and sweet. A tree 50°—70° high, with a trunk up to 2° in diameter, stout spreading and drooping branches, and stout or rarely slender glabrous branchlets, reddish brown at the end of their first season, becoming dark gray-brown. Winter-buds ovoid, acute, glabrous, up to ½′ in length, the inner scales puberulous. Bark close, only slightly ridged, light or dark gray. Distribution. Rochester, Munroe County, New York, through southern Ohio and Indiana to southern Illinois (Tunnel Hill, Johnson County); coast of New Jersey; District of Columbia and southward to the shores of Indian River and the valley of the Callusahatchie River, Florida, and through southern Alabama to western Louisiana; one of the commonest Hickories in the coast region of the south Atlantic and east Gulf states, occasionally ranging inland to central and northern Georgia and western Mississippi. 13.
