The aim of this study was to determine the autecological characteristics of Tanacetum joharchii (Asteraceae), an endemic plant to Iran. Characteristics of sites along with soil properties, phenological stages, life form, conservation status, companion species, palynology and anatomical studies were examined. The results show that this species is distributed in the elevations ranging from 1900 to 2500 m.a.s.l., with the mean annual precipitation of 235.7 to 286.7 millimeters and mean annual temperature of 12.56 to – 14.31 ºC. The Soil texture of the area is silty clay with the Electrical Conductivity of 0.2- 0.4 ds/m and soil pH of 7.94. The vegetative growth of the species starts in late March, flowering in May and seeding in early August. It is a Hemicryptophyte, based on the life form classification of Raunkiaer. The conservation status of the species shows that it may be considered as Critically Endangered based on the IUCN classification. Pollen is Spheroidal, Tricolporate and Echinate- Porforate.
