Ranunculus is the largest genus of Ranunculaceae, with an estimated ۶۰۰ species distributed worldwide, especially with numerous species in the temperate zones. Based on collecting living plants in the field and analysis of ۷۵۰ specimens from various herbaria, ۵۹ species were recognized from Iran. In this paper, the taxonomy of the genus mainly follows that of Farsi version of the genus in Flora of Iran with some changes where necessary. According to these data one new species, four new records, three synonyms, and one status change were proposed during the last ۳۰ years. The taxa are differentiated mainly by the shape and size of their leaves, calyx form, and fruits. Correct names and synonyms are presented. Ecological conditions and habitat of many species were studied by sampling in the habitat. An identification key was prepared and the synopsis of the species is proposed here. Diagnostic characteristic traits are presented for most of the taxa. Selected examined specimens are given for all the taxa.
