Abstract: (1143 Views)

Iran, having about 79 species of the genus Lamiaceae, is one of the regions of origin of this genus. About 77% of the identified species of the mentioned genus in Iran have been registered as exclusive species. There is an Iranian Nepeta species, which was previously taken as a separate species in botanical reference sources, but has been reclassified as a variety of Nepeta kotschyi in the flora of Iran (Jamzad, 2012). In this research, the correctness of the taxonomic position of these two species by examining their various morphological and micromorphological traits such as plant height, leaf size, canopy, type of hairs and nuts, using stereo electron microscope (SEM) photos and SPSS statistical studies. The results of morphological and microstructural studies of the two species N. persica and N. kotschyi showed that there is a significant difference in the characteristics such as the shape of the leaf, the hairs of its apertures and also the height of the two species. Although these differences in the size and shape of the seeds were not clearly observed, in this study, both N. kotschyi and N. persica species had reticulated nuts with papilus. Also, the appearance of the long hairs on the leaves of the two species is completely different. The hairs in N. persica species have papilus, but the hairs in N. persica species have a smooth surface. Therefore, it was suggested that the two species are independent.
