Where Does the Fascicular Cambium Come from?

The vascular cambium is formed in mature dicot stems after stem elongation stops. (A) Primary xylem and phloem differentiate from procambial tissue in the vascular bundles, and a fascicular cambium is formed from procambial tissue separating these tissues.

How is fascicular cambium formed?

Fascicular cambium forms when the procambial cells between the primary xylem and phloem inside the vascular bundles start to divide, whereas interfascicular cambium develops between the bundles.

Where do we find fascicular cambium?

The cambium present in the vascular bundle between the conducting tissue xylem and phloem is called a fascicular cambium. It is also called intrafascicular cambium as it is found within the vascular bundle. The cambium present between two vascular bundles is called an interfascicular cambium.
