Dermal Tissue System
The outer layer of the apical meristem gives rise to the epidermis of the primary plant body (note the diagram below).
In the stems of plants with secondary growth, the epidermis is replaced by periderm, commonly called the "outer bark". Periderm consists of the meristematic cork cambium producing cork (phellem) outward and the phelloderm (inward).
