摘要：This paper is a first contribution to knowledge of the vascular plant species diversity of the NE Adriatic Island of Olib (26.13 km2). The total vascular flora of the island comprises 465 taxa of native and naturalised vascular plants, and 69 commonly cultivated taxa. The Mediterranean character of Olib flora is reflected by a large proportion of taxa belonging to the families Poaceae, Fabaceae and Asteraceae and a clear domination of the steno-Mediterranean plants, accompanied by a high percentage of therophytes. Although a low level of human influence is shown, the presence of exotic taxa outside cultivation has to be monitored due to their potential naturalisation. With this in mind, this article aimed at updating the statuses of the species Ipomoea quamoclit and Aptenia cordifolia in the checklist of Croatian vascular plants.
