Аннотация:Invasive plant species Solidago canadensis, widespread in Russia, occasionally forms hybrids S. × niederederi with the native species S. virgaurea. Previous findings of this hybrid were known mainly for the northwestern regions of Russia. Plants morphologically similar to S. × niederederi were found in August 2020 in the city of Aleksin in Tula Region. The hybrid origin of these plants was proved by the analysis of the nuclear ribosomal internal transcribed spacer 1–2 (ITS1–2). Analysis of the chloroplast noncoding intergenic spacer rpl32–trnL showed that both parent species could act as both maternal and paternal ones in the same population. The available data suggest that individuals of S. × niederederi arise every time as a result of new hybridization events.
