In Texas, limber pine may be found in the Guadalupe and Davis Mountains of West Texas. As the name indicates, the branches and twigs are especially flexible and tough, often light purple in color. The branches form a rounded tree top or head. The trunk is stout and noticeably tapered. The needle-like LEAVES are in clusters of five. They are stiff and stout, about 2 to 3 inches long, and arranged in clusters or tufts near the ends of the branches. They stay on the twig for five or six years. [Illustration: LIMBER PINE (Fruit and leaves, one-third natural size)] The “FRUIT”, a cone, is relatively short or stocky, mostly from 3 to 6 inches long, made up of rounded rather thick scales, some turned forward and some backward. The cone is short-stalked. As with all the pines, the seeds mature at the end of the second season of growth. The WOOD is relatively soft, close-grained, slightly yellowish or reddish. It is not cut in quantity and the trees are usually rather limby and short-bodied, which largely accounts for the small commercial use. PINYON (Nut Pine) Pinus edulis Engelm. Pinyon is found as scattered trees or in small groves over the mountains and canyons in the western part of the state to elevations of 8,000 feet. It is a small tree, grows on warm slopes or in sheltered locations, and forms a bushy top with orange-colored branchlets. The needle-like LEAVES grow in bundles of two (rarely 3); whereas in Pinus cembroides Zucc., the Mexican Pinyon, there are usually three needles per cluster. The dark green needles are approximately one inch long, stiff, stout, and curved. They remain on the tree from 5 to 8 years. [Illustration: PINYON (Natural size)] Like all the pines, it has male and female “FLOWERS” separate on the same tree. The “FRUIT”, a cone, is rounded, about 1 to 2 inches across, and produces large seeds or “nuts”, from ½ to ¾ inch long. The seeds are rich in food value and form an important article of diet for the Indians. The seeds are gathered and sold widely as fancy “nuts” in many larger towns and cities.
