    Centaurea glabro-auriculata (Asteraceae), a new species from Turkey
    (FINNISH ZOOLOGICAL BOTANICAL PUBLISHING BOARD, 2007) Uysal, Tuna; Demirelma, Hakki; Ertugrul, Kuddisi; Garcia-Jacas, Nuria; Susanna, Alfonso
    Centaurea glabro-auriculata Uysal & Demirelma sp. nova (Asteraceae) is described and illustrated from Central Taurus, Turkey. The species grows in stony places in Derebucak (C3 Konya Province). It is morphologically most similar to C. drabifolioides and C. cheirolepidoides, which are likewise endemic to a restricted area within Turkey.

    The examinations of achene ultrastructural features of section Acrolophus (Centaurea, Asteraceae) via scanning electron microscopy
    (TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2016) Candan, Feyza; Uysal, Tuna; Tugay, Osman; Bozkurt, Meryem; Ertugrul, Kuddisi; Demirelma, Hakki
    In this study, the achene surfaces of 31 taxa belonging to the genus Centaurea L. were examined in detail by means of electron microscopy. The main aim of this study was to characterize the microsculpture of the achene surface of the Turkish species of Centaurea sect. Acrolophus (Cass.) DC. (Asteraceae). Detailed descriptions of the achene surface were given for each taxon and a fruitful dendrogram was established by numerical analyses derived from the determined micromorphological features. The relationships among the taxa studied were briefly assessed using this generated dendrogram. The results indicated that the examined taxa had very high variations regarding their achene surfaces and these variations have great importance in determining the taxonomic relationships of the discussed taxa. According to the results, pericarp texture and color could be used for taxonomical diagnosis of the Acrolophus species because they contain differences over a broad spectrum. The fruit coat was usually roguish and its ornamentation was fairly variable; therefore, this taxonomical microcharacter might also be useful in distinguishing closely related taxa. The hairiness of the surface of the pericarp was characteristic in all Acrolophus species and it would be evaluated as a decisive micromorphological character of the section within the genus.

    Karyomorphological study of five Turkish endemic Rhaponticoides Vaill. (Asteraceae, Cardueae) species
    (TAYLOR & FRANCIS LTD, 2016) Uysal, Tuna; Sezer, Ela Nur Simsek; Bozkurt, Meryem; Tugay, Osman; Ertugrul, Kuddisi; Demirelma, Hakki; Dural, Huseyin
    In this paper, we aimed to determine the chromosomal features of Turkish endemic Rhaponticoides species. The chromosome numbers and karyomorphology of five species were examined. The chromosomal counts confirmed the previous reports of 2n = 30 given for Rhaponticoides species growing in different countries. Although R. iconiensis had a karyotype formula of 28m + 2sm, the remaining four species all had 26m + 4sm. Rhaponticoides aytachii and R. hierroi were especially similar in asymmetry indices. Rhaponticoides iconiensis and R. phytiae had satellites in the fourth and second chromosome pairs, respectively. Having the most symmetrical chromosomes, R. amasiensis displayed an important relationship with R. iconiensis and R. phytiae in terms of total chromosome length (TCL). If we make an overall assessment in terms of chromosomal asymmetry, chromosomes indices continues in the low range for each species and this low asymmetry indeces indicate that the species have symmetric chromosomes as karyomorphology. In conclusion, this is the first report which describes the karyotypes and chromosomal asymmetry indices of Turkish endemic Rhaponticoides species.

    A new species of Cousinia (sect. Cousinia, Asteraceae) from the Agri Mountain (eastern Turkey): evidence from morphology, karyology and anatomy
    (MAGNOLIA PRESS, 2019) Tugay, Osman; Ulukus, Deniz; Ertugrul, Kuddisi; Uysal, Tuna; Demirelma, Hakki; Dural, Huseyin
    Cousinia agridaghensis (sect. Cousinia) from Agri province, eastern Turkey, is described as new to science. The new species is morphologically closely related to C. urumiensis, C. fedorovii and C. armena but differs in capitula shape, synflorescence shape, stem height, shape of segments of basal and uppermost cauline leaves. In addition, the new species is compared with C. urumiensis, which is distributed in Turkey, in terms of chromosome number and anatomical features. The basic chromosome number is determined x = 12 in C. agridaghensis and x = 13 in C. urumiensis. The differences in leaf midrib shape and number of vascular bundles in C. agridaghensis and C. urumiensis are observed. The achene coat and pollen grain surface of C. agridaghensis and C. urumiensis are studied with SEM photographs. Furthermore, a detailed description, distribution map, conservation status and ecology of the new species are given.

    Silene kucukodukii sp nov (Caryophyllaceae) from south Anatolia, Turkey
    (WILEY-BLACKWELL PUBLISHING, INC, 2007) Bagci, Yavuz; Uysal, Tuna; Ertugrul, Kuddisi; Demirelma, Hakki
    Silene kucukodukii Y. Bagci & 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 Oil Silene kucukosukii has been carried out and the chromosome number is 2n =24.
