    Contribution to the cytotaxonomic knowledge of 10 species of Klasea Cass. (Asteraceae) from Turkey
    (Firenze Univ Press, 2015) Martin, Esra; Dogan, Bekir; Duran, Ahmet; Coskun, Fatih; Altinordu, Fahim
    In the present study, karyotype analyses of 10 taxa belongs to the genus Klasea Cass. (Asteraceae) were conducted. Somatic chromosome numbers are not a distinctive character of classification of Klasea taxa. All of the taxa were counted as 2n = 30 chromosomes, except for Klasea radiata subsp. biebersteiniana (2n = 60). Although all the taxa have a chromosome number of 2n = 30, they could be differentiated by their karyotype formula and quantitative parameters of the karyotype. Karyotype analysis was performed by means of an Image Analysis System and karyotype asymmetry indices were measured. According to these parameters, karyological relationships among studied taxa were inferred.

    Klasea serratuloides subsp karamanica subsp nov (Asteraceae), from the central and south Anatolia transition zone, Turkey
    (Wiley, 2014) Dogan, Bekir; Duran, Ahmet; Coskun, Fatih
    A new subspecies, Klasea serratuloides (DC.) Greuter & Wagenitz subsp. karamanica B. Dogan & A. Duran (Asteraceae), is described and illustrated from Anatolia, Turkey. The subspecies grows on stony places in the Ayranci and Ermenek district (C4 Karaman Province), Eregli district (C5 Konya province) and Ulukisla (C5 Nigde province) in the central and south Anatolia transition zone. It is morphologically similar to K. serratuloides subsp. serratuloides. Diagnostic morphological characters from closely similar taxa are discussed and arranged in a key. Ecology and conservation status of the subspecies is also presented. In addition, the geographical distribution of the new subspecies and other related species is mapped. The pollen morphology and achene surface of K. serratuloides subsp. karamanica and K. serratuloides subsp. serratuloides were examined by SEM.
