Three years after the publication of the vascular flora of Mount Limbara, we present a revised floristic list with new records of 34 taxa in the study area. Specifically, 15 of these newly recorded taxa are native, while 19 are alien species. Additionally, we have removed 7 taxa from the previous list due to incorrect assignments. Furthermore, we have comprehensively revised the nomenclature, chorology, and distribution of additional 74 taxa within the study area. The inclusion of new alien taxa in our findings increases the already significant number of nonnative taxa identified in this area. Following this revision, the vascular flora of Mount Limbara currently comprises 1,175 taxa, classified into 125 families and 500 genera. The endemic and subendemic taxa are 89, while the alien flora includes 134 taxa. In this report, we highlight the discovery of four casual aliens that are new to the Sardinian flora: Hyacinthoides hispanica, Koelreuteria paniculata, Leucanthemum ×superbum, Ulex europaeus subsp. europaeus. Additionally, we present the first report for the flora of Italy of Eucalyptus ×trabutii (casual alien). Moreover, we confirm the presence of Hyacinthus orientalis for the Sardinian flora, and we exclude Cuscuta cesattiana from the flora of the island. Finally, we remark the invasive status of Abies cephalonica and Xanthium orientale in the area.
