 | | The Calibrachoa leaves could be separated according to the type of leaf margins, the distribution of the stomata on leaf surfaces, the organization of the mesophyll and the morphology of the trichomes. |
 | | In Calibrachoa species, the parenchymatous sheath that surrounded the vascular bundle (endodermis) was formed by developed cells, different from those of the mesophyll (Fig. |
 | | Considering the size of the epidermal cells and the distribution of the stomata in the surfaces, it was possible to recognize in Calibrachoa two different groups of leaves (Table 1): one with the epidermis formed by cells of similar sizes and stomata distributed on both surfaces (Fig. |
