In 2019, an Icelandic fern taxon S. spicant var. fallax was elevated to a species level. The talk will summarize the results of recent taxonomic studies on this interesting plant currently known only from one geothermal site in Iceland. The taxon has been previously known for a long time. It was initially discovered by a danish botanist Christian Grønlund during his excursion to Iceland in 1876, and subsequently described by Johan Lange. Afterwards, this Icelandic fern has been forgotten and neglected in terms of taxonomic research for over a century. Our studies – spanning from nomenclatural to mico-morphologic research clearly showed that the Icelandic morphotype differs significantly from other taxa in western Europe. We will present these differences and discuss the rationale behind treating Icelandic plants as a separate species.
