Improvements in the phylogeny of Epilobium and Chamaenerion inferred from nrDNA and cpDNA data focusing on Türkiye

Epilobium and Chamaenerion included 165 8 species over the world, respectively. The members of genera are distributed particularly in moist habitats from subpolar to tropical regions.This paper aims provide improvements phylogeny using Internal Transcribed Spacer (ITS) nuclear DNA matK gene sequence data evaluation with maximum parsimony, likelihood, Bayesian inference criterations. A total 188 individual accessions belonging 28 taxa were newly generated 110 sequences imported GenBank (NCBI) analysed. nrDNA plastid trees supported treat as separate two well-supported clades. analyses revealed a better resolution than ITS within clade inclusion C. angustifolium sect. Chamaenerion. However, most examined mostly fell into polytomy both excluding E. roseum subsp. consimile which should be considered distinct contrary morphological treatment many national flora books. Both phylogenetic also support distinguishing prionophyllum anatolicum previously treated subspecies anatolicum. In conclusion, these preliminary have contributed significantly determination limits Türkiye.
