Form.—Height 50-75 feet, diameter 2-3 feet; trunk when grown in the forest often tall and free from limbs; crown loose and more or less irregular.

Leaves.—Alternate, compound, odd-pinnate, 8-14 inches long; leaflets 7-21, ovate or oblong, 1-2 inches long, entire, very thin, smooth, dull green above, paler beneath; stipules thorny or spine-like.

Fruit.—A flat pod 3-4 inches long, containing 4-8 small brown seeds.

Bark.—Deeply furrowed into firm, prominent ridges, reddish-brown.

Wood.—Heavy, very hard and strong, close-grained, very durable in contact with the soil, brownish with thin yellow sapwood.

Range.—Pennsylvania to Georgia west to Iowa and Kansas. Naturalized over a large area in America and extensively cultivated in Europe.

Distribution in West Virginia.—Common throughout West Virginia, but most abundant and healthiest in high limestone areas.

Notes.—Black Locust, Yellow Locust, and False Acacia are other names of this tree. According to Sargent’s “Manual of the Trees of North America” locust trees are “most abundant and of largest size on the western slopes of the Alleghanies of West Virginia.” It is a rapid grower, its wood is unsurpassed for many purposes and, as a legume, it adds fertility to the soil wherever it grows.
