XIV OPTIMA Meeting, Palermo (Italy), 9-15 September 2013 Karyotype analysis of Polygonatum species (Asparagaceae) in Turkey YEŞIL Y., ÖZHATAY N. Istanbul University, Faculty of Pharmacy, Department of Pharmaceutical Botany, 34116 Istanbul, Turkey. E-mail: yeteryesil@yahoo.com, nozhatay@istanbul.edu.tr The genus Polygonatum L. (Asparagaceae) comprises 57 species distributed in the temperate regions of the Northern Hemisphere, mainly from the Himalayas to Japan. It is represented by 5 species in Turkey. In this study, the karyotypes of 26 populations belonging to 5 species of Polygonatum from Turkey were analysed. Their chromosome numbers were as follows: Polygonatum glaberrimum C. Koch. and P. latifolium (Jacq.) Desf. 2n= 20; P. multiflorum L. and P. orientale Desf. 2n= 18; P. verticillatum L. 2n= 28. Karyotype analysis showed that the karyotypes of these species consist of metacentric (m), submetacentric (sm), telocentric (t) and subtelocentric (st) centromered chromosomes. Basic chromosome numbers are x=10, x=9 and x=7. Karyotypes of the Turkish species are examined for the first time that collected from wild population in Turkey. 169
XIV OPTIMA Meeting, Palermo (Italy), 9-15 September 2013 A rare and endemic Pimpinella species from Turkey: P. sintenisii AKALIN E. 1 , AŞKIN A. 2 1 Istanbul University, Faculty of Pharmacy, Department of Pharmaceutical Botany, Beyazit/Istanbul, Turkey. E-mail: akaline@istanbul.edu.tr 2 Cumhuriyet University, Faculty of Education, Department of Biology Teaching, Sivas, Turkey. Pimpinella sintenisii Wolff represents a rather critical and still not deeply investigated species within the genus Pimpinella. The species belongs to the having yellow petals of the genus. Pimpinella is one of the largest genera (125 sp.) among the members of Apiaceae. This genus is mainly distributed through subtropical and temperate regions of the northern hemisphere, and the Mediterranean region is one of the most important centres of diversity for this group. Pimpinella sintenisii was firstly collected and described by Sintenis in 1888 as Reutera intermedia, and then the species was moved to the Pimpinella genus by Wolff. This plant is a typical orophyte, occurs on rocks cerevices and has very narrow distribution (Mardin and Siirt provinces in Turkey). Although P. sintenisii is specified that are also occur in Northern Iraq in the Flora of Turkey. The specimen of N Iraq was named P. sintenisii var. cinerea Blakelock was published as a new species “P. nephrophylla Rech. F. H. Rieldl” in 1961. As a result, P. sintenisii was considered as an endemic species from Southeastern region of Turkey. On the basis of field and herbarium investigations, as well as literature, P. sintenisii can be considered a species complex, including several allied species such as Pimpinella nephrophylla Rech.f. & Riedl, Pimpinella paucidentata V.A.Matthews and Pimpinella flabellifolia (Boiss.) Benth. ex Drude are also examined. The present study aims at clarifying the taxonomy, nomenclature, and typification of P. sintenisii. A comprehensive study has been carried out in this species in respect of morphology, anatomy, caryology and fruits. A distribution map of this species is also given. 170
