“…The heterogeneous climate and complex physical geography of the Balkan Peninsula provided a wide range of conditions for different species and vegetation types to evolve in. The patchy, topographically varied landscape of the Balkans, with its mosaic of mountain ranges, islands and peninsulas that acted as migration barriers for most organisms, significantly contributed to the formation of Balkan biodiversity (Stevanovi c, 1996;Reed et al, 2004;Meshinev, 2007;Peev and Delcheva, 2007;Velikov and Stoyanova, 2007;Radford and Odé, 2009) (Greuter, 2006(Greuter, -2009Kaya and Bancheva, 2009)]. Although their mutual phylogenetic relationships remain unresolved, previous genetic studies indicate their close evolutionary relationships.…”

Background and Aims The Balkan Peninsula is one of the most important centres of plant diversity in Europe.Here we aim to fill the gap in the current knowledge of the evolutionary processes and factors modelling this astonishing biological richness by applying multiple approaches to the Cyanus napulifer group.Methods To reconstruct the mode of diversification within the C. napulifer group and to uncover its relationships with potential relatives with x ¼ 10 from Europe and Northern Africa, we examined variation in genetic markers (amplified fragment length polymorphisms [AFLPs]; 460 individuals), relative DNA content (4 0 ,6-diamidino-2-phenylindole [DAPI] flow cytometry, 330 individuals) and morphology (multivariate morphometrics, 40 morphological characters, 710 individuals). To elucidate its evolutionary history, we analysed chloroplast DNA (cpDNA) sequences of the genus Cyanus deposited in the GenBank database.Key Results The AFLPs revealed a suite of closely related entities with variable levels of differentiation. The C. napulifer group formed a genetically well-defined unit. Samples outside the group formed strongly diversified and mostly species-specific genetic lineages with no further geographical patterns, often characterized also by a different DNA content. AFLP analysis of the C. napulifer group revealed extensive radiation and split it into nine allopatric (sub)lineages with varying degrees of congruence among genetic, DNA-content and morphological patterns. Genetic admixture was usually detected in contact zones between genetic lineages. Plastid data indicated extensive maintenance of ancestral variation across Cyanus perennials.Conclusion The C. napulifer group is an example of a rapidly and recently diversified plant group whose genetic lineages have evolved in spatio-temporal isolation on the topographically complex Balkan Peninsula. Adaptive radiation, accompanied in some cases by long-term isolation and hybridization, has contributed to the formation of this species complex and its mosaic pattern.

“…Cass. ex Hayek is distributed throughout central and southern Europe, North Africa, Asia Minor, and the Caucasus, with some species appearing as far east as Iran and Afghanistan, and it currently includes 36 species (Hellwig, 2004;Bancheva & Stoyanov, 2009, Kaya & Bancheva, 2009Boršić et al 2011;Ranjbar & Negaresh 2012;Olšavská et al 2013;Ranjbar et al 2013aRanjbar et al -2013bBancheva & Kaya, 2015;Stoyanov, 2016;Kaya & Özel, 2017;Kaya et al 2018;Şirin et al, 2019).…”

Two new species of Centaurea subg. Cyanus (Asteraceae) from Anatolia are described and illustrated. Centaurea akcadaghensis Uysal & Şirin occurs on open Quercus forest of Levent Canyon (Akçadağ-Malatya) and differs from C. matthiolifolia Boiss. mainly in stem, leaves, central flowers and achenes measures. Centaurea ermenekensis Şirin & Uysal is restricted to steppes of Göktepe (Ermenek-Karaman) and can be distinguished from C. reuteriana Boiss. by the stem, number of capitula, involucre and median appendages measures.

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.
