3  pieces of wax layer
2  epidermal cells

English name: Jade plant, money tree
Scientific name: Crassula ovata
Familia: Crassulaceae
Classis: Dicotyledonas
Phylum: Angiospermae
Regnum: Plantae
The surface of the epidermis of the leaf of Crassula ovata is covered by a layer of wax that efficiently protects the leaf against drought in the atmosphere. The wax layer is normally continuous, like a crust, but here fractures are visible; this damage is an artifact that occurs when making epidermal strips.
