wpeD.jpg (30267 bytes) Beta vulgaris is another good example of a plant in which a degree of anomalous growth occurs. You can see that there is something strange going on in this specimen! The stem contains some  vascular bundles embedded in a pith-like parenchymatous core (look in the ovoid outlined areas and compare the structures of the vascular bundles - they look the same not so?), and immediately exarch of this, is a broad band of tissue which is entirely secondary, which   includes a cambial zone (CZ). This is an example of anomalous growth.
