Honey Locust Leaf

A honey locust leaf.

Leaves - compound; )even-feathered, leaflets, ten to twenty-two or more, usually about fourteen), sometimes twice compound; alternate; edge of leaflets entire as seen above, but as seen below often remotely and slightly toothed. Outline of leaflet - long oval or long egg-shape. Base - and narrowed. Apex - rounded. Leaf/Stem - and very short. Leaflet/Stem - downy. Leaflets - three fourths to one and a half inches long; about one third as wide. Often several of them (one to three) are partly or wholly divided into smaller leaflets. Surfaces smooth and shining. Bark - of trunk, gray, and much less rough than that of the common Locust (which has a somewhat similar leaf); branchlets brown and often warty. The branches and the trunk, excepting in very young and quite old trees, are usually thickly covered with spines, two to four inches long, which are curved at the base, often two- to three-branches, and of a reddish-brown color. Flowers - small and greenish. Fruit - a long, flat pod (nine to eighteen inches long) reddish; somewhat twisted, and filled between the seeds with a pulp which at first is sweet (whence the name "Honey" Locust) but which soon becomes sour. The seeds are flat, hard, and brown. Found - native in Pennsylvania, westward and southward, but also somewhat naturalized and widely introduced northward. General Information - A tree sometimes seventy feet high, with wide-spreading and graceful branches, and light and delicate foliage. It is often used as a hedge plant. A variety entirely bare of thorns (var. inermis) is sometimes found; also a variety (var. brachycarpos) with shorter fruit and thorns.

Leaves - simple; alternate; edge very sharply and slightly irregularly and unequally toothed. Outline - long oval or long egg-shape. Apex - taper-pointed. Base - slightly heart-shaped. Leaf/Stem - about one fourth inch long, and often rough. Leaf - usually three to four inches long, and about half as wide, but with many smaller leaves of varying size on the same branch; smoothish above, paler and somewhat downy below. Ribs - The straight ribs and their angles hairy. Bark - of trunk, brownish or dark gray, and remarkable for being finely furrowed up and down, with the ridges broken into three - to four-inch lengths. These divisions are narrower than on any other rough-barked tree, and they become narrower and finer as the tree grows older. The new shoots are reddish green and dotted with brown; the younger branches purplish-brown and dotted with white or gray. When the branch is two to three inches thick, its bark becomes grayish and begins to crack. Fruit - in long oval, drooping clusters, resembling those of the hop-vine, with long, unlobed scales that lap each other like shingles. August, September. Found - oftenest on dry hill-sides. Common North, South, and West, especially in Southern Arkansas. General Information - A tree twenty to thirty feet high, with white, very strong, and compact wood. It would be very valuable, if it were more abundant and of larger growth.
