He recognised three distinct zones, dermatogen, periblem and pleurome in shoot
and root apical meristems. He called them as histogens or tissue builders. They
perform different functions. Each zone is composed of group of initial cells.

The Plant Cell Cycle and Its Interfaces
The calyptrogen/dermatogen complex was later named as the tier related by
lineage to the root cap and the epidermis (Cutter, 1971). In the interests of
simplicity, we propose the use of the English equivalents for each of these terms
as follows ...
