Sphagnum talbotianum is reported new from Svalbard, based on revised herbarium specimens. We assume that all previous observations and specimens of S. warnstorfii in Svalbard, indeed belong to S. talbotianum. Here, we outline the history behind the discovery and discuss the potential for new establishments of Sphagnum species or populations in Svalbard due to climate change.
