49. BLACK WALNUT

Juglans nigra Linnaeus


Black walnut
is a valuable timber tree native to some areas of New York State. It can reach a large size and produces highly prized wood and large edible nuts. It is common at low elevations in rich, well-drained bottomlands northward to Saratoga and Jefferson Counties and west to Lake Erie. The wood is heavy, hard, strong, durable, rich dark brown in color, easily worked, and takes a fine polish. It is largely used in cabinetmaking, interior trim, and for gunstocks. It deserves protection and planting in suitable locations.


Bark
- thick, dark, deeply furrowed with rounded ridges between; grayish brown in color; inner bark dark chocolate brown in color.

Twigs - at first hairy, later smooth, stout, brittle, orange brown in color, cream-colored chambered pith.

Winter buds - terminal bud pale, downy, scarcely longer than broad, blunt-pointed, less than 1/3 inch long; lateral buds less than 1/6 inch long.

Leaves - alternate, compound, with 13 to 23 leaflets; leaflets 3 to 4 inches long, sharp-pointed, serrate along margin, usually stalkless; leaves up to 2 feet in length.

Fruit - a round nut, 1 1/2 inches in diameter, black, the surface roughened by rather coarse ridges, enclosed in a yellowish green, fleshy husk, usually solitary or in clusters of 2, ripening in October. Kernel - sweet, edible, and when properly cured somewhat easier to extract than the butternut. It is necessary to remove the outer husk if nuts are to be stored.

Distinguishing features - large round nut; cream-colored, chambered pith.
