tailieunhanh - Ekimia ozcan-secmenii (Apiaceae), a new species from Southwest Anatolia, Turkey

Ekimia ozcan-secmenii Şenol & Eroğlu sp. nov. (Apiaceae) is described from SW Turkey. E. ozcan-secmenii differs from its close affinity, E. bornmuelleri, by life form (monocarpic), petal and bracteole morphology, and mericarp features. These data were more supported by the results of nrDNA ITS sequences. | Turkish Journal of Botany Research Article Turk J Bot (2018) 42: 510-517 © TÜBİTAK doi: Ekimia ozcan-secmenii (Apiaceae), a new species from Southwest Anatolia, Turkey Serdar Gökhan ŞENOL*, Volkan EROĞLU, Nazlı Bahar PELİT, Duygu BOZYEL Ege University Botanical Garden and Herbarium Research and Application Center, İzmir, Turkey Received: Accepted/Published Online: Final Version: Abstract: Ekimia ozcan-secmenii Şenol & Eroğlu sp. nov. (Apiaceae) is described from SW Turkey. E. ozcan-secmenii differs from its close affinity, E. bornmuelleri, by life form (monocarpic), petal and bracteole morphology, and mericarp features. These data were more supported by the results of nrDNA ITS sequences. The ML tree depicted based on phylogenetic studies aimed to reveal the closeness of the Laserpitium and Prangos species as well as the location the affinity of species in the genus Ekimia. The taxonomic situation of Prangos hulusi was also evaluated based on nrDNA ITS sequences. Since E. ozcan-secmenii is distributed in Sami Soydam Sandalcık hydroelectric power plant in Acıpayam, Denizli, the population is threatening by flooding. Therefore, conservation programs are urgently recommended. Key words: Apiaceae, Ekimia, internal transcribed spacer (ITS), Laserpitium, new species, phylogeny, Prangos, taxonomy, Turkey 1. Introduction Apiaceae is one of the largest plant families in the world. Turkey is one of the largest centers of biodiversity for the family among Asian countries, with about 160 endemic species included in 44 genera (Bilgili et al., 2016). The flora of Turkey consists of 19 monotypic endemic genera (Pimenov and Leonov, 1993; Güner et al., 2012; Vural et al., 2012; Uysal et al., 2014). Five of the known monotypic genera belong to the family Apiaceae. One of these genera, Microsciadium Boiss. (1844), is not endemic and grows in the East Aegean Islands. Aegokeras Raf. .
