The systematic position of the monotypic genus Ekimia & (Apiaceae), a narrow endemic to Turkey, was evaluated on the basis of morphological data and nrDNA ITS sequences. Ekimia bornmuelleri (. & Reese) & was initially described in Prangos Lindl. Due to the unique fruit morphology uncommon for this genus it was later shifted to an independent genus. | Turkish Journal of Botany Turk J Bot (2015) 39: 673-680 © TÜBİTAK doi: Research Article Systematic placement of the Turkish endemic genus Ekimia (Apiaceae) based on morphological and molecular data 1, 2 3 2 Dmitry LYSKOV *, Galina DEGTJAREVA , Tahir SAMIGULLIN , Michael PIMENOV 1 Department of Higher Plants, Biological Faculty, Moscow State University, Moscow, Russia 2 Botanical Garden, Biological Faculty, Moscow State University, Moscow, Russia 3 Department of Evolutionary Biochemistry, . Belozersky Institute of Physico-Chemical Biology, Moscow State University, Moscow, Russia Received: Accepted/Published Online: Printed: Abstract: The systematic position of the monotypic genus Ekimia & (Apiaceae), a narrow endemic to Turkey, was evaluated on the basis of morphological data and nrDNA ITS sequences. Ekimia bornmuelleri (. & Reese) & was initially described in Prangos Lindl. Due to the unique fruit morphology uncommon for this genus it was later shifted to an independent genus. In the Bayesian and most parsimonious trees, E. bornmuelleri is sister to Laserpitium petrophilum Boiss. & Heldr and Laserpitium glaucum Post within the Daucinae clade. This result is consistent with its morphology: the presence of the primary and secondary ribs of E. bornmuelleri fruits brings the species closer to Laserpitium rather than Prangos.

Introduction Ekimia bornmuelleri (. & Reese) & is a narrow endemic to the Turkish province Burdur in Central Anatolia, where it was collected for the first time in 1938. Huber-Morath and Reese described this species in the genus Prangos, due to resemblance of immature fruits to fruits of Prangos lophoptera Boiss. (Huber-Morath, 1945). The .
