“…In this study, more than 400 surveys were conducted in 300 areas across 27 provinces of Iran. The "Flora Iranica" as well some new Iranian literature (e. g. Mehrabian et al, 2013;Mehrabian, Amini Rad, 2018;Mehrabian, Mozaffarian, 2018) and the website of Tropicos (www.Tropicos.org) and IPNI (www.IPNI.org) were used to determine nomenclature and species description information.…”

“…Onosma L. is the third large genus of plants in the borage family, Boraginaceae, with nearly 240 species of the biennial to perennial herbs (Popov, 1950(Popov, , 1974Zemskova, Popova, 1991;Jian-Chang et al, 1995;Mehrabian et al, 2013;Cecchi et al, 2016;Mehrabian, Amini Rad, 2018;Mehrabian, Mozaffarian, 2018;Khajoei Nasab et al, 2020a) distributed in mountain steppe of the Irano-Turanian region of Asia along with the Mediterranean region, especially Iran and Turkey (Meusel et al, 1978;Mehrabian, 2015;Cecchi et al, 2016;Khajoei Nasab et al, 2020b;Mehrabian et al, 2022a, b). So far about 69 plant taxa of this genus have been reported in Iran, many of which are endemic to the flora of Iran (Mehrabian, Amini Rad, 2018;Khatamsaz, 2002;Attar et al, 2020). Despite the importance of this genus in the world, there are few geographical and ecological studies on Onosma in the world.…”

Conservation of biological diversity is one of the most important issues in conservation biology, so a wide range of quantitative spatial methods have been used to determine the biodiversity hotspots and the conservation priority areas. The main aims of the present study are determining the areas of endemism as well as the centers of diversity of the genus Onosma based on the GIE, IPAs, species richness, and AZE-like criteria approaches, to assess the status and priorities of conservation of the mentioned genus in Iran. Based on the findings of this research, centers of species richness, the main areas of endemism, top-ranked IPAs, and AZE-like criteria are situated in the Zagros ecosystems. The comparison of the four approaches used in this study shows that the IPAs and GIE techniques have succeeded in identifying the most important centers of diversity and endemism of Onosma in Iran. Considering that this genus with a high percentage of endemic species is one of the most important genera of Iranian flora and only 46 % of the IPAs and areas of endemism specified in the research are located in protected areas, identification and protection of the rest of these areas is one of the prevalent measures needed for conservation of Onosma species diversity in Iran.

“…Afterwards, Khatamsaz (2002) provided taxonomic notes in the Flora of Iran with a similar classification to that of Riedl, reporting 37 species. Research on Onosma including systematics (Mehrabian et al, 2011 b; Sheidai et al, 2015; Khajoei Nasab et al, 2020a), palynology (Mehrabian et al, 2012), micromorphology (Azizian et al, 2000; Mehrabian et al, 2014; Mehrabian et al, 2017), ecology and geobotany (Mehrabian, 2015; Moradi Zeinab et al, 2019; Naghizadeh et al, 2020; Khajoei Nasab et al, 2020 b, c), and description of new species (Mehrabian et al, 2013; Mehrabian and Mozaffarian, 2018; Mehrabian and Amini Rad, 2018) has been carried out by the Onosma study team at Shahid Beheshti University, Iran. According to Mehrabian (2015) and recent new studies (Mehrabian and Mozaffarian, 2018; Mehrabian and Amini Rad, 2018; Dehshiri, 2018), Onosma includes about 56 specific taxa in Iran, of which 41 species (73%) are endemic.…”

Two new species and a new record for Onosma L. (Boraginaceae) from northwestern Iran

Onosma atrii and O. persica are described and illustrated as new species and O. caucasica Levin is recorded for the first time from northwestern Iran. The two new species are placed in subsect. Asterotricha (Boiss.) Gürke, because of the asterotrichous indumentum (stellate trichomes) of their basal leaves. An extensive review of the literature and comparison with specimens from various European and Asiatic herbaria led to the recognition of these novelties. Our argument for these innovations is based on observation of significant differences in taxonomically important morphological characters including trichome type, shape and size of basal and cauline leaves, shape and size of calyx and corolla, annulus hairs, anther length, connection type and degree of exsertion, and nutlet morphology. The diagnostic morphological characters of closely related species are discussed, and for each new species a detailed description and details of distribution and conservation status are provided. An updated synoptical key to the species known from the Flora Iranica region and Atropatene sub‐province is provided.

“…The genus Onosma is one of the most important genera of Boraginaceae in Iran as it is comprised of a large number of species and has a high rate of endemism. So far, 54 species of this genus have been reported in Iran, 24 of which are endemic to the flora of Iran (Khatamsaz, 2002;Mehrabian and Amini, 2018). Moreover, this genus has medicinal properties and the root of its plants contain a major active chemical component known as shikonin (Sut et al, 2017).…”

Climate change may cause shifts in the natural range of species especially for those that are geographically restricted and/or endemic species. In this study, the spatial distribution of five endemic and threatened species belonging to the genus Onosma (including O. asperrima, O. bisotunensis, O. kotschyi, O. platyphylla, and O. straussii) was investigated under present and future climate change scenarios: RCP2.6 (RCP, representative concentration pathway; optimistic scenario) and RCP8.5 (pessimistic scenario) for the years 2050 and 2080 in Iran. Analysis was conducted using the maximum entropy (MaxEnt) model to provide a basis for the protection and conservation of these species. Seven environmental variables including aspect, depth of soil, silt content, slope, annual precipitation, minimum temperature of the coldest month, and annual temperature range were used as main predictors in this study. The model output for the potential habitat suitability of the studied species showed acceptable performance for all species (i.e., the area under the curve (AUC)>0.800). According to the models generated by MaxEnt, the potential current patterns of the species were consistent with the observed areas of distributions. The projected climate maps under optimistic and pessimistic scenarios (RCP2.6 and RCP8.5, respectively) of 2050 and 2080 resulted in reductions and expansions as well as positive range changes for all species in comparison to their current predicted distributions. Among all species, O. bisotunensis showed the most significant and highest increase under the pessimistic scenario of 2050 and 2080. Finally, the results of this study revealed that the studied plant species have shown an acute adaptability to environmental changes. The results can provide useful information to managers to apply appropriate strategies for the management and conservation of these valuable Iranian medicinal and threatened plant species in the future.
