Photographic reconstruction of the complete thickness of the leaf observed with the objective of 40x. From top to bottom we can distinguish the following structures: externally is located the upper epidermis (whose cells show a thick translucent cuticle), next the hypodermis and, below, the mesophyll. The mesophyll is integrated by the spongy and palisade parenchyma, identifiable by the disposition and morphology of the cells, some of which are idioblasts, containing crystalline groupings in form of druse. In the spongy parenchyma are visible two vascular bundles, one of them in cross-section (surrounded by the pod of the bundle), and part of another cut longitudinally. The lower epidermis shows invaginations or stomatal crypts, provided with stomata (zone framed in red, detail in other microphotography) and covered by numerous unicellular trichomes
