The sharply pointed and usually sharply toothed leaves, 2]^ to 3>4 inches long by 1^^ to 2 inches broad, are thin and somewhat hairy beneath on the midrib and veins, with petioles usually less than Yz inch long. The flowers are not dis- tinctive, but the dark-purple, globular fruits, about Vt, inch in diameter, have dark orange flesh and hang from stems j/2 to "JA inch long. The slender, red- brown branchlets bear oval, flattened |)ointed buds about J4 inch long, anc the trunk, usually not over 2 feet in diameter, is covered by dark-brown bark roughened by irregular, wartlike excrescences or by long ridges. The tree is usually between 40 and 50 feet high. Distribution: From New Eng- land to \ irginia and westward to Ne- braska and Kansas, the Hackberr}' is a fairly common tree on rocky hills and ridges, but it is not found often on low ground. It ranges over the entire State of Illinois. Excepting the Post Oak and Scrub Oak types of upland woods, all of our hardwood forests contain Hackberry. It is most abun- dant in the drainage basin of the Ohio River, and occurs commonly with Pin Oak, Elm, Honey Locust, Soft Maple, cottonwoods. Burr Oak, Ash, Red Gum, and hickories. In the northern part of the State, its commoner associates are Elm, Ash. maples, Walnut, Burr Oak, and Bass Wood. VestaP describes a well- defined Elm-Hackberry forest in Cumberland County, in which also occur Honey Locust, Black Haw, and, in some places. Shingle Oak. He Delieves that, as the Hackbeiry seeds are readily dispersed to considerable distances, "these forests are of independent and comparatively recent origin in locally favorable spots in the prairie ;.
