Nepeta baytopii (sect. Schizocalyx) and N. sorgerae (sect. Subinterruptae) are the two endemic species of the genus Nepeta L. in Turkey. In this paper, this two Nepeta species which are in two different sections are examined anatomically. In this study, it was investigated on stem-leaf anatomy and trichomes micromorphology of these Nepeta species in order to improve our knowledge of its anatomy for systematics and to help separate the species. The anatomical characters of the species, such as stem and leaf are described in detail. The anatomical results were compared to the same investigations done before. In anatomical studies, cross-sections of stems and leaves were examined and are supported by illustrations and photographs. Also, trichomes in stems and leaves were investigated by LM and SEM. Anatomical characters of the species were observed to be similar to the usual features of Lamiaceae anatomy. Finally, these two species are different for serriate of pericycle, collenchyma, xylem and phloem. And the trichome covers of these two species are different from each other
