WebMedullary cells are present in all trees. In the softwoods they are microscopic, not seen by the unaided eye. In the hardwoods they show a wide diversity in size. The rays in basswood are very small and are inconsequential visually. Ray cells are often stacked vertically and can form large bands of tissue in the wood. WebThe intrafascicular cambium, as well as the cells of the medullary rays which are lying along the line of the fascicular cambium, also becomes meristematic. The intrafascicular and interfascicular cambia form a ring which separates the primary xylem and primary phloem and is known as cambium ring. It is the first step of secondary growth.
