Abstract: | A remarkable population of Carex extensa (Cyperaceae) was found south of Lake Fert? (Neusiedler See) in Hungary in 2012. This species typically occurs in coastal salt marshes in Europe and was hitherto unknown from the Pannonian Basin. The locality is situated in a territory which has been embanked in 1911. Keeping also in mind that the vegetation developed here from reed beds to saline habitats, we conclude that C. extensa reached the salt marshes of the area through long distance dispersal by water birds from the European coast in the last century. Nevertheless, several other maritime littoral species grow in the region, and the possibility that there is a hidden population of C. extensa at another site(s) nearby cannot be excluded. Lake Fert? is often described as the “westernmost steppe lake” and supports one of the richest European inland littoral floras. Although it appears likely that C. extensa has only recently colonised the site, we consider this discovery to be of significant biogeographical importance. |
