. Field crop production; a text-book for elementary courses in schools and brief courses in colleges. Agriculture. LEGUMES FOR FOB AGE AND GRAIN 313 variety from a single upright, branching stem to a pro- fusely trailing form. Almost all varieties, have the trail- ing habit of growth, and under favorable conditions of climate and soil some of them produce stems 15 feet or more in length. The stems are marked with longitu- dinal grooves, and the color of the stems is associated with that of the leaves, varying in this respect from pale to dark green. The leaves are trifoliate and are larger than those of the soy bean. The flowers are borne singly and are much larger than those of the soy bean, being more nearly the size of those of the sweet pea. The flowers are whitish, violet, or yellow in color, and rival the sweet pea in beauty. The pods are long, straight, or slightly curved, and many seeded. The seeds vary greatly in size and may be either smooth or wrinkled. They vary also in color, the common colors being white, yellow, green, brown, and mottled. The stem, leaves, and pod of the cowpea, unlike those of the soy bean, are not covered with hair. In appearance the cowpea more closely resembles the field and garden bean than it does the soy bean. The root system of the cowpea consists of a well-devel- oped tap root, which gives off lateral branches from the upper part. These grow out horizontally for some distance and then grow downward rather deeply. The roots of the cowpea are more extensive than those of the soy bean, being more numerous and penetrating more deeply into the Fig. 114. — Pods of cow- peas and soy Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Livingston, George.
