The development and configuration of the cork cells may change periodically during the formation of periderm.

When in this manner a continuous layer of cork arises, steadily increasing from the inside, it is termed “periderm.”

As the epidermis is at first replaced by the periderm, so in turn is this replaced by cork (the dead tissue).
