For example, dur- ing the early growth of the Corn plant, the leaves are closely packed around the growing point of the stem and only the outer ends of the blades are well exposed. But through the elongation of the internodes, all of the leaves are finally separated, so that at the time the tassel and ears appear all portions of the leaves receive light. The way leaves are arranged on the stem is also an important feature in securing proper exposure. There are three common arrangements, alternate, opposite, and whorled. In the alternate arrangement, there is but one leaf at a node and they appear to alternate, first on one side of the stem, then on a different 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 Martin, John N.
