=Fruit.=--October. Generally sessile on terminal peduncles, single or in pairs, as large or larger than the fruit of the shagbark, or as small as that of the pignut, oblong-globose to globose: husk hard and thick, separating in 4 segments nearly to the base, strong-scented: nut globular, 4-ridged near the top, thick-shelled: kernel usually small, sweet, edible. The superior size of the fruit and the smallness of the kernel probably give rise to the common name, "mockernut." =Horticultural Value.=--Hardy throughout New England; prefers a rich, well-drained soil, but grows well in rocky, ledgy, exposed situations, and is seldom disfigured by insect enemies. Young trees have large, deep roots, and are difficult to transplant successfully unless they have been frequently transplanted in nurseries, from which, however, they are seldom obtainable. Propagated from seed. [Illustration: PLATE XXV.--Carya tomentosa.] 1. Winter buds. 2. Flowering branch. 3. Sterile flower, front view. 4. Sterile flower, side view. 5. Sterile flower, top view. 6.

Niagara peninsula and along Lake Erie. Maine,--frequent in the southern corner of York county; New Hampshire,--common toward the coast and along the lower Merrimac valley; abundant on hills near the Connecticut river, but only occasional above Bellows Falls; Vermont,--Marsh Hill, Ferrisburgh (Brainerd); W. Castleton and Pownal (Eggleston); Massachusetts,--common eastward; along the Connecticut river valley and some of the tributary valleys more common than the shagbark; Rhode Island and Connecticut,--common. South to the Gulf of Mexico; west to Minnesota, Nebraska, Kansas, Indian territory, and Texas. =Habit.=--A stately tree, 50-65 feet high, reaching in the Ohio basin a height of 120 feet; trunk 2-5 feet in diameter, gradually tapering, surmounted by a large, oblong, open, rounded, or pyramidal head, often of great beauty. =Bark.=--Bark of trunk dark ash-gray, uniformly but very coarsely roughened, in old trees smooth or broken into rough and occasionally projecting plates; branches gray; leaf-scars rather prominent; season's shoots smooth or nearly so, purplish changing to gray, with numerous dots.
