Abstract

The Micromorphology of Ligule epidermis was investigated in 28 species from 16 genera of the tribe Lactuceae using scanning electron microscope. The study showed that some of these charecters have a good taxonomic importance to distinguish between the studied taxa, such as the shape of epidermal cells and the ornamentation of the outer cell walls. The presence or absence of stomata, waxy deposited and the nature of anticlinal walls were found to be valuable at generic and species level.
