| This simple diagram tries to illustrate the basic events which take place in the development of the Vascular Cambium and Secondary Vascular Tissues. The continuation of meristematic activity within the Fascicles and the development of the Interfascicular Cambium leads to the formation of a continuous layer of Vascular Cambium in the stem. The accumulation of Secondary Xylem leads to the development of internal pressure. This crushes some cells in the Pith and Phloem. |
