During the long-term study, based on field and many herbaria specimens, three new species including R. iranshahrii Taheri & Assadi sp. nov., R. kordestanicum Taheri & Assadi sp. nov. and R. austro-iranicum Taheri & Assadi sp. nov. were discovered in Iran. In this paper, all new species are compared with their putative relatives. Botanical characters are elaborated and a brief taxonomic synopsis for all accepted species is also provided.
