medullary rays
In dicot stems, the cells of cambium present between primary xylem and primary phloem are the intrafasicular cambium. The cells of medullary rays, adjoining these intrafascicular cambium become meristematic and form the interfascicular cambium. Xylem parenchyma is living and thin-walled and their cell walls are made up of cellulose. In dicot roots, the innermost layer of the cortex is called endodermis. Next to endodermis lies a few layers of thin-walled parenchymatous cells called as pericycle.
