Abstract

To determine the evolutionary relationships among some members of geophytes collected from their natural habitat in Kulp-Diyarbakır we carried out molecular phylogenetic analysis of one nuclear DNA (nrDNA) region (internal transcribed spacer, ITS) and one chloroplast DNA (cpDNA) region (intergenic spacer region of trnL-F). Despite phylogenetic analysis using maximum likelihood done by two different DNA source show some differences it was identified that monocotyl petaloid taxa differ from dicotyledone geophyte ones. Also both phylogenetic trees reveal that Serapias, Anacamptis, Cephalanthera, Himanthoglossum and Dactylorhiza are nested in Orchis. Therefore the infraspecific relationships of these genera should be re-evaluated according to our molecular phylogenetic study results. Dicotyl geophyts show molecular phylogeny in accordance with the classical systematic order in Flora of Turkey and reveal the accuracy of interspecific and infraspecific distinctions of these taxa.
