Vascular cambium - Wikipedia
The cambium present between primary xylem and primary phloem is called the intrafascicular cambium (within vascular bundles). During secondary growth, cells of medullary rays, in a line (as seen in section; in three dimensions, it is a sheet) between neighbouring vascular bundles, become meristematic and form new interfascicular cambium (between vascular bundles). The fascicular and interfascicular cambia thus join up to form a ring (in three dimensions, a tube) whi…
