Abstract

The occurrence of Helianthemum jonium Lacaita & Grosser ex Bég. in Fiori & Bég. (Cistacaeae) is reported and documented here for the first time in Croatia and Montenegro, and it is confirmed in the Albanian flora after 80 years. The species grows on sandy soils within maquis and garrigue communities in four Adriatic islands: Vis, Biševo, Hvar and Lopud, and within psammophilous vegetation near Ulcinj in Montenegro and in Hamallaj, north of Durrës in Albania. The morphological relationship with the allied H. leptophyllum Dunal and H. apenninum (L.) Mill. is here briefly discussed. Remarks about its taxonomy, lectotypification, habitat and ecology in the Adriatic region are also provided. The species H. jonium was previously known only from the Apennine Peninsula; hence these new eastern Adriatic records extend its distribution area to the east, and it can therefore be considered an amphi-Adriatic endemic element.
