Abstract
Damasonium polyspermum Coss. occurs only in the Mediterranean, and is relatively rare across the whole distributional range. It grows in shallow standing water bodies with significant fluctuations of the water level, and it is considered characteristic for Mediterranean temporary ponds, which are rare and endangered habitats. According to IUCN, D. polyspermum is globally vulnerable (VU). In Croatia this species is denoted as data deficient (DD), however, more recently it was proposed to category endangered (EN), to critically endangered (CR). Until this record, there were only two known localities of D. polyspermum in Croatia, both in Northern Dalmatia. In June 2014 we have discovered a new locality of D. polyspermum in the area of Vrana Lake in Northern Dalmatia. Due to the specific ecological requirements which account for the small number of findings, new localities of D. polyspermum represent a significant contribution to the knowledge on its distribution.
