LOCATION OF VASCULAR CAMBIUM In Dicots: The vascular cambium is in dicot stems and roots, located between the xylem and the phloem in the stem and root of a vascular plant, and is the source of both the secondary xylem growth (inwards, towards the pith) and the secondary phloem growth (outwards). Parenchyma and it forms secondary xylem and primary phloem is called the intrafascicular (! Mycorrhizae 4.5. This tissue is called vascular cambium.
