“…The first revision of Centaurea in Turkey was made by (Wagenitz 1975), who recognized 172 species and six doubtful species. Since then, 35 new species have been identifed and two species recorded from Turkey (Uysal 2012, Bona 2015, Negaresh et al 2015, Yüzbaşıoglu et al 2015, Kültür et al 2016, Uysal and Hamzaoglu 2016, Uysal et al 2016a, 2016b, Pınar 2016, Behçet et al 2017, Negaresh & Rahımınejad 2018, Armagan and Uysal 2018, Şirin et al 2019Duman et al 2021, Özbek 2021, Hamzaoglu et al 2020, Aslan et al 2010. According to latest studies the genus Centaurea was divided into four genera, namely Centaurea s. str.,Rhaponticoides Vaill., Psephellus Cass.…”

A new species, Centaurea osmaniyensis (Asteraceae) was described and illustrated here and is only known from Bahçe district in Osmaniye Province in Türkiye. The species belongs to sect. Cynaroides Bunge and it is closely related to C. regia subp. cynarocephala. The ecology and phenology of new species, descriptions, images, the identification key, seed, pollen micromorphology and the IUCN threat category of the new species were presented. In addition, the geographical distribution of Centaurea osmaniyensis and C. regia subp. cynarocephala were provided

“…It is one of the larger genera of the Turkish flora and has the highest endemism rate. Presently, with the latest additions, the genus comprises 219 taxa (Duman et al 2021, Özbek 2021), bringing the endemism rate to 59% (Şirin et al 2019b). The members of the genus are mainly distributed in the Mediterranean and the Irano‐Turanian regions of Turkey.…”

A new Centaurea species, C. mengenensis Uysal & Şirin, is described and illustrated from Mengen district, Anatolia, based on morphological and molecular data. To identify its taxonomical position within Centaurea, the internal transcribed spacer (ITS) = gene region of the new species was amplified and sequenced. The new species belongs in Centaurea subg. Centaurea as shown by both morphological and molecular data. Its diagnostic characters are presented, including an updated key to related species distributed in Turkey. Additionally, the geographic distribution of the new species, as well as of its relatives, is mapped. The chromosome number of C. mengenensis is 2n = 2x = 18 and its achene surface ornamentation is irregularly sulcate.

“…Turkey is a center of diversity for Centaurea. Recently, with the latest additions, the number of Centaurea species has reached to 220 in Turkey [4][5][6][7]. Therefore, the endemism rate is approximately 60%.…”

Centaurea amaena is an endemic and endangered species listed as CR (critically endangered) in Turkey. ISSR markers were used to detect the level of genetic diversity in two natural populations of C. amaena. A total of 50 ISSR primers were used and 13 primers producing polymorphic and reproducible products were selected. These primers yielded 102 amplified discernible loci, of which 80 (78%) were polymorphic. A high level of genetic diversity was detected both at population and species levels; the effective number of alleles (Ne) was 1.544, the observed number of alleles (Na) was 1.784, the Nei?s genetic diversity (H) was 0.306, and Shannon's information index was 0.447. The established gene flow (Nm) was 2.329, indicating a high migration rate between the populations. A moderate level of genetic differentiation (GST: 0.176) was also observed. Analysis of molecular variance (AMOVA) revealed that 24.89% of the total genetic diversity resided among populations, while 75.10% was within the populations. Cluster analysis showed that samples from the same locality clustered together and there was no cross-clustering between the samples. The patterns of genetic variation indicate that existing C. amaena populations should be conserved.
