The LEAVES occur in pairs or whorls of 3 (occasionally more) each oval or elliptical, pointed, rounded at the base, from 2 to 7 inches long by 1 to 3 inches wide. They are thin, dark green above, with a large central midrib, and somewhat hairy beneath. They fall in autumn or remain on branchlets over winter. The FLOWERS form a creamy white or yellow round head about 1 inch in diameter and are borne in clusters. The many small flowers in the head are fragrant and nectar-bearing. The long thread-like projecting styles are conspicuous on the flowering heads. The FRUIT consists of a mass of nuts in a globular head forming an aggregate fruit ¾ inch in diameter. The red-brown nutlets have 2 to 4 closed, 1-seeded portions. The WOOD is of little value. RUSTY BLACKHAW (Viburnum) Viburnum rufidulum Raf. Rusty blackhaw is found in woods and thickets over East Texas. It forms a tree, sometimes 35 feet high, with a trunk over a foot in diameter, but is usually much smaller, often flowering as a shrub. The twigs are ashy-gray, becoming dark dull reddish-brown after one to several years. The winter buds are densely covered with rusty brown hairs which persist for some weeks at the base of the leaf-stalks. The BARK is ¼ to ½ inch thick, becoming roughened into small plate-like, dark brown scales tinged with red. [Illustration: RUSTY BLACKHAW (Fruit and twig, three-quarters natural size; leaf, two-thirds natural size)] The simple LEAVES are opposite or whorled, elliptic to obovate or oval, pointed or blunt at the apex, wedge-shaped or rounded at the base, and with fine teeth on the margin. They are leathery in texture, lustrous dark green above, pale and dull below, about 3 inches long, and 1 to 1½ inches wide. The FLOWERS are small and white; each has five petals and five stamens, and appear in the spring in dense clusters at the tips of branches. The FRUIT ripens in the fall. It is a bright blue, oval drupe, over ½ inch long, covered with a glaucous bloom, and containing a stony seed ¼ inch long and ⅓ inch wide. The bad smelling WOOD has no economic use. Other Texas Trees ARIZONA CYPRESS (Cupressus arizonica Greene) is an evergreen native to the mountains of the south Trans-Pecos Region. It grows from a height of 30 to 70 feet and 18 to 24 inches in diameter. The needles are blue-green. Fruit a cone as large as 1¼ inches in diameter. The wood is heavy and used to some extent for fence posts. ALLIGATOR JUNIPER (Juniperus deppeana Steud.)
