Distribution, taxonomy, nomenclature and molecular genetic data are presented for two closely related pairs of birch taxa: 1) dark-barked Betula pubescens var. sibakademica (Baran.) Kuzeneva (basionym B. sibakademica Baranov) and white-barked B. pubescens Ehrh. var. pubescens, and 2) dark-barked B. kotulae Zaverucha = B. pendula var. obscura (Kotula ex Fiek) Olšavská (basionym B. obscura A. Kotula ex Fiek, heterotypic synonym B. kotulae Zaverucha) and white-barked B. pendula Roth, respectively. Using published data and sequences obtained in this study, it was found that while these pairs can be distinguished not only by morphological characters but also by two diagnostic single nucleotide polymorphisms (SNPs) in the internal transcribed spacers ITS1 and ITS2, no sequence differences within each pair were detected. These results suggest that the color of the bark cannot be used as a taxonomic trait at the species level, and the dark-barked birches within each pair should not be treated as separate species, but as varieties, respectively. Therefore, we reassessed the taxonomical status of B. sibakademica and B. kotulae using both morphological traits and molecular genetic markers and suggest that B. pubescens var. sibakademica (Baranov) Kuzeneva and B. pendula var. obscura (Kotula ex Fiek) Olšavská should be used to name them, respectively. B. pubescens var. sibacademica was described in Ukraine for the first time.
