Rediscovery of <i>Aldrovanda vesiculosa</i> L. and new data on its distribution in the Republic of Macedonia

Abstract

Aldrovanda vesiculosa L., widely known as the waterwheel plant, is a rare aquatic plant that holds the status of a globally endangered (EN) species. Extant populations of A. vesiculosa are rare in Europe and there are only few sites left in the Balkans. In Macedonia, the species was last recorded in 1980 and according to many researchers the plant was considered as extinct in the area. In this paper, we present the recent finding of Aldrovanda vesiculosa and new data on its distribution in Macedonia, including an assessment on the specific habitat type and evident threats.
