The FLOWERS of both sexes appear on the same tree and open with the leaves. The FRUIT, a head an inch or more in diameter, is made up of many capsules with projecting spines. It hangs on the tree late into the winter. The WOOD is moderately hard, close-grained, and not durable on exposure. The reddish-brown heartwood, which suggests the name red gum, is not present to any appreciable extent in logs under 16 inches in diameter. The wood is extensively used for flooring, interior finish, paper pulp, and veneers for baskets of all kinds. In the uplands, this species competes aggressively with the more valuable Southern pines. The control of sweetgum is, therefore, a problem. This attractive species should be more widely planted for ornamental use. AMERICAN SYCAMORE Plantanus occidentalis L. American sycamore, also called planetree and buttonwood, is considered the largest hardwood tree in North America. It occurs throughout eastern Texas to Zavalla County. It is most abundant and reaches its largest size along streams and on rich bottomlands. It grows rapidly and occasionally attains a height of 140 to 170 feet and a diameter of 10 to 11 feet. The BARK of the sycamore is a characteristic feature; on the younger trunk and large limbs it is smooth, greenish-gray in color. The outer bark of limbs and upper trunk flakes off in large patches and exposes the nearly white younger bark. Near the base of old trees, the bark becomes thick, dark brown and divided by deep furrows. [Illustration: AMERICAN SYCAMORE (Fruit and leaf, one-third natural size)] The LEAVES are simple, alternate, 4 to 7 inches long and about as broad; light green and smooth above, and paler below. The base of the petiole is hollow and in falling off exposes the winter bud. The multiple FRUIT forms a ball about 1 inch in diameter, which hangs on its flexible peduncle—3 to 5 inches long. During early spring the fruit ball breaks up, and the small nutlets are scattered widely by the wind. The WOOD is hard and moderately strong, but decays rapidly in the ground. It is used for butchers’ blocks, tobacco boxes, furniture, and interior finish. HAWTHORN (Haw) Crataegus L. Hawthorn, as treated here, represents about 30 different species and varieties distributed throughout the state. Members of the group occur on the poorest and richest soils, on the shallowest and deepest, and on the limestone hills as well as on the rich bottom and swamp lands. Most of the forms have a common likeness in possessing thorns and bearing white blossoms and red or yellow fruit. Some species are planted as ornamental trees, but otherwise the group is of little commercial value. [Illustration: HAWTHORN (Leaf and twig, two-thirds natural size; fruit, one-half natural size)]
