AbstractThe leaves of Stevia rebaudiana, from Asteraceae family, are a source of steviol glycosides, which are utilized as a sweeter, more favorite addition. Among the most important anatomical results that were reached through the research and which distinguish the plant from an anatomical point of view are uniseriate-multicellular of non-glandular trichomes that are covered the epidermis of stem and leaves. Also, the vertical walls of the ordinary epidermis cells in the upper and lower epidermis that are heavily sinuous and the stomata scattered in both of it, the type of the stomata anomocytic. In addition, the mesophyll which differentiated into 2-3 layers of palisade cells under the upper epidermis and the spongy cells after it and the cross-section of midrib region of the leaf as crescent shape and the vascular bundle central, crescent shape.
