In this work the vascular flora of the “Bosco Isola” at Lesina (Foggia, Apulia). which is almost included within the Gargano National Park, is analysed. The study was carried out taking into account soil, climate and bioclimate that are the main factors affecting the chorological and bio- logical aspeets. In total 678 taxa of subgeneric rank were found, 521 by field investigation and 157 by litera- ture, that are equivalent to 32,67% of the entire Apulian flora. 19 of them are new to Apulia and 131 10 the “ Bosco Isola”. In the studied arca there were ascertained 161 and 28 subgeneric taxa more than in previous works concerning the Lesina area and the whole Apulia, respectively. ‘The chorological spectrum shows the dominance of the Mediterranean elements and. even if to a lesser extent, some others occurring under cooler and more humid climates.
