This investigation dealt with the study of the style and stigmatic characters of 13 Egyptian species, 9 belonging to genus Erodium and 4 to genus Geranium using both the stereo- and scanning electron microscopes. The studied characters are the hair density and type on the style, length, width, shape and epidermal characters of the stigma. The obtained results revealed that the most important character in distinguishing between the two genera is the length and shape of stigma, while the hair density, type, length can be of use in the identification of the species under these two genera. G. dissectum and G. rotundifolium are the only two species with multicelluler capitates glandular hairs, while E. moschatum is the only species with short unicellular hairs. From this study, we can conclude that the taxa in family Geraniaceae have great similarity in their floral characters and need more detailed studies to unveil the diagnostic features between them.
