Part 27

A tree, often 100° high, with a tall straight trunk 2°—3° in diameter, stout spreading branches forming a broad handsome head, and slender branchlets marked by oblong pale lenticels, bright green and covered more or less thickly with rusty hairs when they first appear, reddish brown and glabrous or puberulous during their first summer, reddish brown and lustrous during the winter and ultimately light gray, with small elevated obscurely 3-lobed obcordate leaf-scars. Winter-buds compressed, scurfy pubescent, bright yellow; terminal ⅓′—¾′ long, oblique at apex, with 2 pairs of scales; lateral 2-angled, often stalked, ⅛′—¼′ long, with ovate pointed slightly accrescent scales keeled on the back. Bark ⅓′—¾′ thick, light brown tinged with red, and broken into thin plate-like scales separating on the surface into small thin flakes. Wood heavy, very hard, strong, tough, close-grained, dark brown, with thick light brown or often nearly white sapwood; largely used for hoops and ox-yokes, and for fuel.

Distribution. Low wet woods near the borders of streams and swamps or on high rolling uplands often remote from streams, southern Maine to Quebec and Ontario, the northern shores of the Lower Peninsula of Michigan, northern Minnesota, southeastern Nebraska, eastern Kansas, eastern Oklahoma, and southward to northwestern Florida, Dallas County, Alabama, and eastern Texas; generally distributed, but not very abundant in all the central states east and west of the Appalachian Mountains; ranging farther north than the other species, and growing to its largest size on the bottom-lands of the lower Ohio basin; the common Hickory of Iowa, Nebraska, and Kansas.

A natural hybrid, × _C. Brownii_ Sarg. of _C. cordiformis_ with _C. pecan_, with characters intermediate between those of its supposed parents, occurs on bottom-land of the Arkansas River near Van Buren, Crawford County, Arkansas. Probably of the same parentage is the so-called Galloway Nut found in Hamilton County, Ohio. Another hybrid, × _C. Brownii_ var. _varians_ Sarg., probably of the same parentage also, occurs near Van Buren. × _C. Laneyi_ Sarg., a natural hybrid evidently of _C. cordiformis_ with _C. ovata_, has been found in Rochester, New York, and trees considered varieties of the same hybrid, var. _chateaugayensis_ Sarg., occur near the mouth of the Chateaugay River, Province of Quebec, and at Summertown, Ontario.

4. Carya aquatica Nutt. Water Hickory.

A tree, 70°—90° and occasionally 120° high, with a tall straight trunk 3°—4° in diameter, in the forest often free of branches for 50°—60° above the ground and then divided into a few small limbs forming a narrow head, or with more space sometimes dividing near the ground or at half the height of the tree into stout slightly spreading limbs, forming a narrow inversely conic round-topped head of more or less pendulous branches, and stout branchlets marked with oblong pale lenticels, covered at first with caducous brown scurf and coated with pale glandular pubescence, soon bright reddish brown, and lustrous, glabrous or pubescent, growing dark gray in their second year and ultimately light gray, and marked by pale and slightly elevated ovate semiorbicular or obscurely 3-lobed leaf-scars. Winter-buds: terminal broadly ovoid, rather obtuse, ½′—¾′ long, ⅓′—½′ broad, the 3 or 4 outer scales nearly triangular, acute, dark brown, pubescent and hirsute on the outer surface, the exterior scales often abruptly narrowed into long rigid points and deciduous before the unfolding of the leaves, the inner scales lustrous, covered with resinous glands, yellow-green often tinged with red, oblong-obovate, pointed, becoming 2½′—3′ long and ½′ broad, usually persistent until after the fall of the staminate aments; axillary buds coated at first with thick white tomentum, becoming ⅓′—½′ long when fully grown. Bark light gray, ¾′—1′ thick, separating in thick plates often a foot or more long and 6′—8′ wide, and more or less closely attached to the trunk by the middle, giving it the shaggy appearance to which this tree owes its common name. Wood heavy, very hard and strong, tough, close-grained, flexible, light brown, with thin nearly white sapwood; largely used in the manufacture of agricultural implements, carriages, wagons, and for axe-handles, baskets, and fuel. The nut is the common Hickory nut of commerce.

× _Carya Nussbaumerii_ Sarg. with leaves like those of _C. laciniosa_, slender branchlets, and large fruit of the shape of that of the Pecan but without sutural wings and white or nearly white nuts, believed to be a hybrid of these species, has been found near Fayetteville, St. Clair County, Illinois, at Mt. Vernon, Posey County, Indiana, near Burlington, Des Moines County, Iowa, and from the neighborhood of Rockville, Bates County, Missouri.

Trees intermediate in character between _C. laciniosa_ and _C. ovata_ growing on the bottoms of the Genessee River at Golah, Munroe County, New York, and believed to be hybrids of these species, are × _C. Dunbarii_ Sarg.
