| Abstract | ||
| Leaf epidermis structure of 13 Fagonia taxa has been studied by Light microscope (LM) and Scanning electron microscope (SEM). Anomocytic stomata type, different trichomes features, cuticular ornamentation and stomatal levels are determined. Results allow clear definition and identification of the taxa. Among all the studied characters, cuticle ornamentation and trichomes features were noticeable to characterize each taxa of Fagonia. The present studies recorded about 27 different trichomes,18 glandular, 8 non-glandular and one special structure trichome. Some taxa were free from glandular trichomes and others were free from non-glandular trichome beside the taxa which have the two types of the trichomes. Three types of trichome ornamentation are recorded in these work; smooth, papillose and warty. The cuticular ornamentation recorded three types’ favulariate, straiated and wrinked. On the basis of observation we created a key for distinguishing Fagonia taxa. | ||
