The cytogenetic investigation of some species of the Ranunculus L.(Ranunculaceae) distributed in Bitlis and its surroundings

The genus Ranunculus L. has 84 species in Turkey, when subspecies and varieties are included in this number, it is represented by a total of 102 taxa, 22 of which are endemic, the endemism rate is 21.5%. In this study, the karyological characteristics of the species R. diversifolius Boiss. & Kotschy, R. poluninii Davis and R. crateris Davis that are distributed around the province of Bitlis were determined. These two species R. poluninii and R. crateris are endemic and Iran - Turan element. The species R. diversifolius is distributed in Eastern Turkey. All three species whose chromosomal characteristics were examined are diploid and chromosome numbers are x=8, 2n=16. These three species that are morphologically similar were found to be different in terms of their chromosome morphology and each species had its own characteristics.
