During investigation of the genus Bufonia L., in various herbaria of Iran, a new species, B. iranica Z.Rostami, Assadi & F.Ghahrem., sp. nov., was recognized and thus is described here. This new species is closely related to B. enervis, with some morphological differences such as size and shape of the perianth, and the seed shape. A key for the species occurring in Iran, illustrations and a distribution map of the new and related species are provided. The seed morphology was studied using a scanning electron microscope.
