Abstract. Verbascum birjandense and V. urumiense are described as new endemic species of Verbascum from eastern and northwestern Iran. It was not possible to assign the samples of these two taxa to any of the known Verbascum species in Iran and adjacent regions. Collating the morphological characters of the samples against the specialized and pertinent literature of the genus led us to propose them as new species. Both belong to section Bothrosperma, subsection Fasciculata. These new species are morphologically close to V. erianthum and V. songaricum based on some key characteristics, but show some differences in basal leaves shape, pedicel size, the ratio of pedicel to calyx, presence of hairs inside the corolla, and the hair color of the stamen’s filaments.

A new endemic species from north of Iran: Verbascum parsana Sotoodeh, Attar & Civeyrel, sp. nov. is described. Considering the combination of some characteristics like ebracteolate and single flowers, violet hairs on filaments, pedicel size between 3 to 10 mm and stellate-glandular indumentum, the new species is related to Verbascum punalense Boiss. & Buhse, but several differences have been observed between the two species: the shape of the anthers, the petiole of basal leaves, the corolla size and the calyx hairs. We investigate the genetic distance of the new species with close genera using ITS and plastid regions (trnS-G, trnL-F, trnH-psbA and partial matK). The new species showed significant molecular and morphological distance from closely related species. Photos and distribution map are presented.
