Description:
<jats:p>Ranunculus pedatus is a Eurasian species with a northern distribution edge in southern Slovakia. In the nineties of the 20th century, it was assumed that the species probably occurs only near Štúrovo. Occurrence in the Hron and Ipeľ basins and several localities in the Podunajská nížina lowland between Komárno and Štúrovo was considered historical. Our research was conducted in the field and herbarium collections of 15 herbaria in Austria, the Czech Republic, Hungary, and Slovakia. Except for the well-known occurrence on salt habitats north of Štúrovo, we confirmed the recent occurrence of R. pedatus in Štúrovo town, around Chľaba village and in Ipeľ Basin (Pastovce, Tupá). The new, easternmost Slovak locality was found near the village of Koláre. Recently, 30% of all known sites were confirmed, so we propose reclassifying the species in Slovak Red List from the category critically endangered (CR) to the category endangered (EN). It occurs in salty meadows of the alliance Festucion pseudovinae (class Festuco-Puccinellietea) and in mesic meadows of alliance Arrhenatherion elatioris and Deschampsion cespitosae (class Molinio-Arrhenatheretea).</jats:p>
