Abstract:A micromorphological analysis of leaf epidermal tissue of 18 Trifolium species was carried out using light and scanning electron microscopy, in order to obtain qualitative and quantitative data on epidermal characteristics and to evaluate their taxonomic significance. The shape of epidermal cells and their cell walls, epidermal wax depositions, presence of papillae, type and number of stomata, type, distribution and number of non-glandular and glandular trichomes were analyzed. The results showed that species that belong to the same section had some common leaf epidermal characteristics. Combinations of those characters proved to be useful in taxonomy at the level of the sections, but not for identification of single species.
Keywords:Leaf epidermis  Stomata  Taxonomy  Trichomes  Trifolium
