Just as stem and leaf of the plant transform themselves into the blossom, so does the bark continue, as it were in metamorphosis, into the outer bark. This transformation takes place as, in the place of the epidermis, a secondary cambium, the cork cambium (*Phellogen*), forms. The cork-cell tissue arising from this binds together and encloses the outward layer of bark that dies away year by year, and with it the mineral inclusions contained therein, as well as the less readily volatile aromatic compounds.
