Little mechanical tissue is present in the leaf. The epidermis is composed of 

 fairly large cells very heavily cutinised (fig. 13). The stomates are sunken below 

 the general level of the epidermis, and the guard cells are protected by an 

 upstanding collar formed by the projection of the cuticle of the adjacent 

 epidermal cells. This appears as a ridge in fig. 13.
