Popis: Arenaria bernensis (Caryophyllaceae), traditionally placed within the Arenaria ciliata aggregate and discovered only in 1955, is a poorly studied endemic taxon of western Prealps in Switzerland. In this study, we aimed to deliver the first detailed appraisal on morphology, distribution and ecology of A. bernensis accompanied by first molecular insights into the A. ciliata aggregate using chloroplast (cp) DNA markers. Altogether 18 populations attributed morphologically to A. bernensis were found during our field surveys. The distribution area of A. bernensis forms an irregular line of ca. 50 km from the south-west (Dent de Lys, FR) to the north-east (Stockhorn, BE). The taxon counts globally ca. 4,000 individuals and the majority of populations are small (
