Sažetak
Island of Hvar is one of the few Dalmatian islands whose flora has been explored over a long period of time since the first half of the 19th century until our days. The first known data on the island’s flora dates back to as early as 1818. According to all the available sources, 1245 plant taxa have been recorded on the island so far, including neighbouring islets. Recent botanical field study was carried out in the period between 2017 and 2022 in all seasons. Several interesting new or rare vascular plant taxa for the island were registered. The luxurious population of the rare short-living fern, Anogramma leptophylla (L.) Link, was found in the olive grove in the vicinity of the Stari Grad, being the fourth recent finding in Croatia. Another fern, Adiantum capillus-veneris L., registered on Hvar only in 1852, was found on several localities within the old town of Hvar, growing on shaded city walls within chasmophytic vegetation. Two rare South African allochthonous species, Senecio angulatus L. f. and Oxalis pes-caprae L. were found for the first time on the island. The first species shows invasive behaviour – beside several populations cultivated in gardens and graveyard, three garden escapees were found in the cities of Hvar and Jelsa. Among new island plant species is one rare, or more probably under- studied autumn flowering daffodil Narcissus serotinus L., flowering in large populations near city of Vrboska. The inventory of the Mediterranean temporary ponds revealed several floristic novelties, e.g. macrophytic Ranunculus peltatus Schrank and Potamogeton nodosus Poir., as well as procumbent annual grass Crypsis schoenoides (L.) Lam. which proliferate on the desiccated pond bottoms during the summer droughts. The same ponds keep the populations of extremely rare charophyte Tolypella intricata (Roth.) Leonh., being the second known locality in Croatia.
