Our aim was to survey the current distribution of https://doi.org/10.3391/bir.2020.9.4.02 Solidago ×niederederi, a hybrid that has originated through spontaneous hybridisation Received: 29 May 2020 between the native European S. virgaurea and allochthonous (North American) Accepted: 24 August 2020 S. canadensis. Although this hybrid was first recorded at the very end of the 19th Published: 20 October 2020 century, most occurrences have been reported during the last decades.
