A longitudinal section of a corn stem thirty to forty days of age shows that the majority of the various primordia of the plant have been differentiated. All nodes are formed but packed very closely together (less than one inch in length); the apex of the stem is differentiating to form the tassel; the leaves are well differentiated and wrapped very tightly about the young staminate inflorescence; eight to ten buds are visible in the axils of the leaves; and vascular bundles exist in all stages of differentiation and development. The bundles in the base of the stem are differentiated more than those near the apex, and the central bundles of the stem are more differentiated than those of the peripheral areas.
