| The leaf of the privet has a multilayered under epidermis with a thick cuticle (xeromorph characteristics; the plant is a xerophyte). The stomata are enclosed and show a complex anatomy, the so-called double-door system: not only the guard cells but also the subsidiary cells are involved in the closing mechanism of the stomata. The typical ledges of the subsidiary cells form a kind of chamber that limits desiccation. |
