Top of Page Secondary Stem Tissues: In dicots and gymnosperms the majority of the plant tissue is composed of secondary vascular tissues. Top of Page Vascular Cambium: The vascular cambium is a layer of meristematic tissue that lies between the primary phloem and primary xylem.As the vascular cambium adds new xylem cells toward the inside of the stem and phloem cells toward the outside of the stem, the vascular bundles eventually coalesce to form a complete ring.op of Page Secondary Stem Tissues: In dicots and gymnosperms the majority of the plant tissue is composed of secondary vascular tissues.
