By the formation of a layer of cambium between the bundles (interfascicular cambium), a complete ring is formed, and a regular periodical increase in thickness results from the development of xylem on the inside and phloem on the outside.
In plants with secondary growth, the vascular cambium, originating between the xylem and the phloem, forms a cylinder of tissue along the stem and root.
For example, developing cells in the meristems contain small provacuoles and cells of the vascular cambium have many small vacuoles in the winter and one large one in the summer.
Dried cambium strips may be made into a nutritious flour by placing them in a blender until a fine, golden colored flour is produced.
The vascular cambium produces new layers of secondary xylem annually.
They contain no cambium and once formed the stem increases in diameter only in exceptional cases.
