Cutandia maritima is a circum-Mediterranean species that inhabits sandy dunesalong the coast line. It is fairly frequent on the western Adriatic coast but fairlyrare and possibly even non-native in the east. In Croatia, it was discovered in1990 in Crnika Bay on the island of Rab, which was considered until 2005 to bethe only site on the eastern Adriatic coast from the Gulf of Trieste in the northto Corfu in the south. In 2009, the species was briefly reported for Velika plaža(Long Beach) in Ulcinj (Montenegro) but without details about the habitattype and synecology. Te aim of this paper is thus to provide a deeper insightinto the ecology and synecology of C. maritima in the eastern Adriatic part ofthe distribution area. On Velika plaža in Ulcinj, the species was found along thewhole sea-inland gradient of sand dunes, in various types of vegetation: [1210]– annual vegetation of drift lines, [2110] – embryonic shifting dunes, [2120]– shifting dunes with Ammophila arenaria (white dunes), [2220] – dunes withEuphorbia terracina, [2130*] – fxed coastal dunes with herbaceous vegetation(grey dunes), and also [2190] – humid dune slacks
