There are many medicinal plants in Iran but there is lack of information about plants' growth condition and application. Autecology is a science which can help us to investigate seasonal and morphological changes and condition that effect on plant distribution. In this study, the autecology and phonological studies for P.abrotanoides were done. At first, vegetation habitats of this plant were chosen in different regions of Kashan and six sites were selected. The observation and recording of plant in dormancy and activity periods were done every 15 and 7 days, respectively. All samples for measurement were selected randomly. This research revealed the temperature, air humidity and soil condition necessary for plant growth and development. During the two years of study, no pest or diseases were seen. This can be attributed to the existence of high amounts of plant essence. No ecological study has been done on this plant yet in Iran. Regarding to its vast distribution in Iran, other autecology studies are needed for comparing different habitats of this plant species.
