Abstract: 

The Zizphora L is one of the genuses of Labiatae family with four species and ten subspecies. Ziziphora tenuior L is one of these genus members, which naturally grows throughout Iran. These plants have medical values in traditional medicine of Iran and used as food spicies aswell. In this study in order to investigate the effect of various ecological factors such as height, kind of soil, water, air and metals on morphological structure, 12geographical population of this species had been collected from their natural habitat and 17 qualitative and quantities morphological attributes with 4 repetition from growth and productive organs had been studied and the dendrogram had been drown on the basis of the above-mentioned attributes. The results of this study showed that the environmental factors and adaphic independent of each other and with each other affect the morphological properties of these plants and give rise to varieties in form. Among the environmental factors under consideration, the genus of soil had the minimum of effect and the type of habitat and height had maximum effect on the growth and production organs. Based on the results of this study, it can be claimed that: species which have a wide range of spreading in the nature and grow in different geographical regions are not consistent in the range of spreading, but rather under the influence of different ecological factors adapt themselves to their habitat and varieties in the morphological form of plants they, will create and cause phenotypic plasticity which we can consider them as types of adaphic and geographical ecotypes.
