• Resumen

  • Results of a karyological analysis of eight species collected from northeast Anatolia, Turkey are presented. The following chromosome numbers were determined: 11. medianiforme (LITV. et ZAHN) JUXIP 2n=36, H. karagollense (ZAHN) P.D. SELL et C. WEST 2n=36, H. argillaceoides (LITV. et ZAHN) JUXIP 2n=36, H. amblylepis BOISS. 2n=27, H. lanceolatum V1LL. 2n=27, H. asterodermum (WORONOW et ZAHN) JUXIP 2n=27, H. umbellatum L. 2n=18, H. laevigatum WILLD. 2n=27. The chromosome numbers of five of these seven species are presented for the first time. The results show a high proportion of triploids and tetraploids within the taxa studied
