“…The west Iran region (especially Kermanshah Province) is a botanically interesting area, because it is belonging to the Irano–Turanian phytogeographical region and is very rich in local endemic plants (Wagenitz , , Martins , Negaresh and Rahiminejad ). Recently, many new species have been described from this special region, such as Onosma bisotunensis (Attar and Hamzeh'ee ), Satureja kermanshahensis (Jamzad ), Cyanus ouramanicus (Ranjbar et al ), Centaurea shahuensis and C. ravansarensis (Ranjbar et. al.…”

A new species, Centaurea rahiminejadii Negaresh (Asteraceae) in C. sect. Cynaroides Boiss. ex Walp., is described and illustrated from the Kermanshah Province, west Iran. It is morphologically similar to Centaurea regia Boiss. subsp. regia. Diagnostic morphological of this and closely related taxa are discussed and presented. The ecology, habitat and conservation status of the new species are also described. In addition, Centaurea regia subsp. cynarocephala (Wagenitz) Wagenitz is reported as a new record to the flora of Iran. Finally, the geographic distribution of the new species and closely related species is presented and mapped.

“…and Rhaponticoides Vaill. Shortly before and following these new treatments, Centaurea s.s., underwent many changes and was considerably expanded by the description of new taxa (Wagenitz and Esfandiari 1983, Akhani 1999, Ranjbar et al 2012, 2013a, Ranjbar and Negaresh 2013a, 2013b, 2013c, 2014c, 2014d, Negaresh and Rahiminejad 2014, 2015.…”

lanceolate or linear-lanceolate, involucre ovoid or ovoid-subglobose, radiant; appendages decurrent, ciliate, not ending in mucro or mucronulate, laceration absent, with blackish or brownish border, usually ovateoblong or ovate-triangular; florets usually violet or blue, rarely whitish, yellowish, pink, or red; marginal florets with 5-6 lobes, sterile, without staminodes, central flowers hermaphrodite; achenes generally ovoid-oblong, insertion areole hairy, mostly with pappus, pappus scabrose or barbellate-scabrose (Wagenitz, 1975). During our field study, some specimens belonging to subgenus Cyanus were collected and then identified according to Flora of Turkey (Wagenitz, 1975). Some clear morphological differences between the collected specimens and C. bourgaei enabled us to describe them as a new species. 2. Materials and methods The new species material was compared to the herbarium collections of Centaurea in ANK, HUB, GAZI, ISTF, ISTE, and KNYA (acronyms follow Thiers, 2018). The morphology of the specimens was examined under a binocular microscope, and the specimens were compared with closely related species: C. bourgaei, C. pichleri, and C. reuteriana. Moreover, the type specimens of the related species were viewed as digital photographs. The achenes of 2 species were dehydrated in an alcohol series (70%, 80%, 96%, and 100%) for cleaning and coated with gold for viewing under a ZEISS EVO LS-10 model scanning electron microscope (SEM) on high-vacuum mode to observe their surfaces at magnifications of 30×, 1000×, and 2000×. The terminology of the achene characteristics was according to Stearn (1995) and Koul et al. (2000). Mature achenes were selected and germinated for chromosomal analysis. Counting of the chromosomes was conducted during the somatic metaphase using the squash technique. Primer root meristems were used to obtain the metaphase plates. The samples were pretreated with 0.002 M 8-hydroxyquinoline for 8 h at 4 °C and then fixed with Carnoy's solution for 24 h at a low temperature. Prior to dyeing, the material was hydrolyzed with 5N HCl for 30 min at room temperature and stained with 1% acetoneorcein. The preparates were made permanent according to the method of Bowen (1956). At least 5 metaphases were examined and the best image was photographed at Research Article This work is licensed under a Creative Commons Attribution 4.0 International License.
