Abstract: During a survey of the genus Onosma L. section ProtonosmaPopov subsect. RostellataeRiedl, we examined several populations assigned to Onosma rostellata Lehm. (sensu lato) using morphology and molecular evidence. Our morphological review revealed a hairy corolla outside in all specimens, an anther length equal to the filament length, and nectariferous rings hairy or glabrous, as opposed to the descriptions provided in Flora Iranica and Flora of Turkey. We updated itsdescription which were in contradiction with the character states found on the type specimen. Five new taxa were identified among the specimens identified as O. rostellata to date and described based on molecular data and morphological examination: Onosma khatamsazii Attar, Mirtadzadini & Sotoodeh – a new species from Kermanshah province, O. fareghanensis Attar, Mirtadzadini & Sotoodeh – a new species from the mountainous region of the north of Hormozgan province, and Onosma maharluensis Attar, Mirtadzadini & Sotoodeh – a new species including two subspecies, namely : O. maharluensis Attar, Mirtadzadini & Sotoodeh subsp. maharluensisand O. maharluensis subsp. boyer-ahmadica Attar, Sotoodeh & Mirtadzadini from Iran.
Abstract: Two new species of Cousinia are described from Iran. Cousinia bornmulleriana from the west that can be placed in sect. Haussknechtii based on some key characters such as flower numbers, phyllary numbers and the inflorescence form traits. This species can be also compared with its closest relative C. haussknechtii. and C. karkasensis. The second new species, C. semnanensis, from North East of Iran, belongs to the sect. Stenocephalae for its flower numbers, winged stem, and phyllaries shape, and is compared to C. alexeenkoana and C. glaucopsis as its close relative.
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 species of the genus Potentilla L. (Rosaceae) from the Tehran province (Iran)
Potentilla alborzensis Faghir & Attar, sp. nov. (Rosaceae) is collected from steppe Mountains of Tang-e Washi, in the middle of Alborz Mountains for the first time. The new species is related to section Aureae (Rydb.) Juz. for its palmate radical leaves, having straight hairs and glandular trichomes; corymbiform inflorescence; hairy and glandular sepals; clavate and papillose style, shorter than or as long as matured ovary. Detailed micro- and macromorphological descriptions of the newly collected species, as well as photographs and distribution map are provided. In addition, comparison of diagnostic traits with allied species especially P. crantzii (Crantz) Beck ex Fritsch, P. adenophylla Boiss. & Hohenack., P. gelida C. A. Mey., P. geranioides Willd. and identification key are presented.
Onosma khorramabadensis,O. lorestanica,O. sahandica and O. kerendica are described and photographed as new species from Lorestan, Eest Azarbayejan and Kermanshah provinces of Iran.
