BLACK WALNUT (Leaf, one-fifth natural size; [fruit], one-fourth natural size; twig, about natural size)
The [FRUIT] is a [nut], borne singly or in pairs, and enclosed in a solid green husk which does not split open, even after the nut is ripe. The nut itself is black with a very hard, thick, finely ridged shell, enclosing a rich, oily, edible kernel.
The [HEARTWOOD] is heavy, hard and strong. Its rich chocolate-brown color, freedom from warping, and checking, susceptibility to a high polish, and durability make it highly prized for furniture and cabinet work and gunstocks. Walnut is easily propagated from the [nuts], and should be more widely planted and grown for timber and nuts.
LITTLE WALNUT or TEXAS WALNUT (Juglans microcarpa Berlandier) is found on limestone banks of streams in western Texas. The stumps supply a beautiful veneer.
PECAN
Carya illinoensis (Wangenh.) K. Koch
Pecan, the “State tree” of Texas, is found native in the state from the Piney Woods west throughout Central Texas, centering in the watershed of the Colorado River. It makes an excellent shade tree and is very valuable for the [nut] crop it bears. Many varieties are planted in orchards. The pecan is a tall-growing tree, attaining heights of over 100 feet. When grown in the open it forms a large, rounded, [symmetrical] top.
The outer [BARK] is rough, hard, tight, but broken into [scales]; on the limbs it is smooth at first but later tends to scale or divide as the bark grows old.
The LEAVES resemble those of the other hickories and the black walnut. They are made up of 9 to 17 [leaflets], each [oblong], toothed and long-pointed, and 4 to 8 inches long by about 2 inches wide.
