Silene kucukodukii Y. Bağcı & Uysal sp. nov. from the Hadim, (C4 Konya‐Turkey) is described and illustrated. It is closely related to S. sipylea O. Schwarz from which it differs morphologically mainly by the indumentum, leaf and floral features. Diagnostic morphological characters are discussed and a key of related Silene L. species in Turkey is given. The geographical distribution of the new species and other related species is mapped. Notes are also presented on its ecology, biogeography and conservation status. A chromosome count on Silene kucukodukii has been carried out and the chromosome number is 2n=24.
Nine chromosome counts in several genera of the tribe Hedysareae from Turkey, six species of Onobrychis, two species of Hedysarum and one species of Sartoria, were reported and all karyotypes were prepared. Six of them are new. One of the other three reports is a confirmation of polyploidy, another report is a confirmation of chromosome count and the last report is a confirmation of both chromosome count and karyotype morphology. Except for karyotype of O. altissima, all karyotypes were presented in this study first.
Abstract Based on sequence data of the nuclear ITS and plastid matK , trnL ‐ F and psbA ‐ trnH markers of 162 species (169 accessions), the relationships and monophyly of tribe Hedysareae and its close relatives were assessed, with special reference to the infrageneric phylogeny of Hedysarum . The results showed that Hedysareae sensu Lock is not monophyletic, and its relationships with tribe Galegeae are unclear. Tribe Galegeae is polyphyletic. Hedysareae sensu Lock includes two strongly supported clades: the Caraganean clade and the Hedysaroid clade. Tribe Caraganeae Ranjbar was supported to be recognized based on the Caraganean clade, but it is herein suggested to be re‐circumscribed by excluding Chesneya and Gueldenstaedtia . Our results support treating the Hedysaroid clade as tribe Hedysareae, comprising nine genera: Alhagi , Corethrodendron , Ebenus , Eversmannia , Greuteria , Hedysarum , Onobrychis , Sulla and Taverniera . Hedysarum as delimited here consists of three main clades: the first clade (the mesic group) corresponds to H . sect. Hedysarum ; the second clade (the xeric group) is the re‐defined H . sect. Multicaulia , consisting of the core group of H . sect. Multicaulia plus the former genus Sartoria ; and the third clade (the psychrophilic group) includes the monospecific H . sect. Stracheya (with H . tibeticum ) and two species previously placed in H . sect. Multicaulia ( H . kumaonense , H . lehmannianum ).
The identification of species based on anatomical characters is valuable to investigate their taxonomic status, phylogeny and understand their autoecology. The current study analysed the stem and leaf properties of 20 species of the subgenus Cyanus (Mill.) Hayek in Turkey. The Cyanus species exhibited xeromorphic anatomical features, such as tight palisade parenchyma and induced spongy parenchyma, which indicated adaptations to the arid soil and a forest ecosystem in which they occurred, as well as to high light intensity and precipitation. Anatomical features such as the midrib shape and number of vascularization patterns differed among the species. Similar anatomical characters were analysed for the investigated species. These properties can provide an important database for future studies including the phylogeny within the subgenus Cyanus. Bangladesh J. Plant Taxon. 28(2): 295-309, 2021 (December)
Draba (kayadolamasi) cinsine ait olan dort taksonun [Draba bruniifolia Steven subsp. bruniifolia (kaya dolamasi), Draba heterocoma Fenzl (tuylu dolama), Draba haradjianii Rech. f. (Hatay dolamasi) ve Draba nemorosa L. (orman dolamasi)] tohum morfolojileri, taramali electron mikroskobu (SEM) ile incelenerek taksonomik karakter olarak onemleri belirlendi. Makro- ve mikromorfolojik karakterleri, tohum rengi, sekli, kanati, olcusu ve tohum yuzey modeli incelendi. Iki tohum yuzeyi modeli (duzensiz-retikulat, duzenli-retikulat ve cukurcuklu) gozlendi ve dort tane de tohum sekli (ovat, dar ovat, eliptik ve genis eliptik) tespit edildi. Sonuclar tohumlarin morfolojik karakterlerinin taksonlarin ayrimina katki saglayabilecegini gostermistir.

Twenty-seven chromosome counts are reported in 23 species of the genus Centaurea, mostly eastern endemic species of the Jacea group, which has become the core of the re-defined genus Centaurea. Twenty reports are new, one is a correction of a previous count, one is a confirmation of limited previous data and one represents a new basic number in the Centaureinae. The prevalence of the basic chromosome number x = 9 among the Eastern sections of the Jacea group is confirmed, together with the close correlation between karyological data and classification of the genus. Two alternative hypotheses on the aberrant chromosome number (for the Centaureinae) found in C. behen are proposed. One of them, if verified, would confirm that a cycle of polyploidy and descending dysploidy is a key mechanism in the speciation of the group.
