They are distributed in the temperate part of Asia and eastern North America. Fossil representatives of this genus have been reported from Europe. Three species are native to eastern North America, one Inhabiting Texas, one the southern and south-central United States, and one described here. The generic name is in commemoration of the German botanist, John Gottlieb Gleditsch. FORM—A medium-sized tree usually from 40-50 ft. high with a diameter of 1-2 ft. but may reach a height of 140 ft. with a diameter of 4-6 feet. Trunk usually short but when, grown in very close stands may be rather clean and long. Crown broad, obovate, round-topped, high on account of lateral drooping branches. BARK—On young trunks smooth covered with many, very conspicuous, raised, oblong lenticels; on old trunks grayish-brown to almost black, sometimes smooth but usually roughened by a few fissures and thick, firm, broad ridges with projecting edges. Bark on trunks is often covered with many thorns. See Figs. 59 and 04. TWIGS—Rather stout, zigzag, smooth, glossy, with enlarged nodes; greenish-red to brown, covered with few, small, scattered lenticels which become larger in time; pith thick and white. Twigs frequently bear thorns which are often branched and contain reddish-brown pith. BUDS—Alternate; terminal bud absent; small, usually 3-5 at a node, placed one above another; upper ones scaly and visible, lowest one not scaly, nor visible except as a dot. Some buds are slow in dOA elop
