The Fascicular vascular cambium, interfascicular cambium and cork-cambium are examples of lateral meristems and are responsible for the secondary growth in dicotyledonous plants.
In dicot stems, the cells of the cambium present between the primary xylem and primary phloem are the intrafascicular cambium. Additionally, the cells of medullary rays, adjoining this intrafascicular cambium become meristematic and form the interfascicular cambium. Thus, a continuous ring of cambium is formed.
