Despite the wide amount of scientific contributions published on alien plant species, their diffusion dynamics, and their interactions with native taxa, it is increasingly difficult to slow down their spreading and their negative impact on habitats. Last recent years, in fact, a sharp rise in the number of new alien plant taxa introduced in Italy and Europe has been recorded. The aim of this work is to investigate most of the Italian territory in order to verify whether this alarming trend is still underway. Specimen collections and/or observations of alien plants have been performed in as many as 12 Italian regions. All the collected specimens are stored in public or private herbaria. Taxa have been identified according to the literature from the countries of origin of the investigated taxa, while the nomenclature followed the current international references. Updates on 106 taxa are reported. In particular, among 117 new records, 89 are first records, 27 are changes to status and there is 1 extinction. Seven new taxa for Italian alien flora are reported, two of which are new to Europe. The administrative regions with the highest number of records are Calabria (48), Sardegna (17) and Sicilia (15). Five of the surveyed taxa, for the first time, have been considered invasive aliens to Italian territory. The unfrequent amount of original results provided by this work, over the simple importance of data itself, proves how floristic investigation, still today, represents one of the most effective tools in broadening the current knowledge about alien taxa and their dynamics.
尽管关于外来植物物种、它们的扩散动态以及它们与本地分类群的相互作用已发表了大量科学文献，但减缓它们的传播及其对栖息地的负面影响却越来越困难。事实上，近年来，意大利和欧洲引入的新外来植物分类群数量急剧上升。这项工作的目的是对意大利大部分地区进行调查，以核实这一令人担忧的趋势是否仍在继续。已在多达12个意大利地区对外来植物进行了标本采集和/或观察。所有采集的标本都保存在公共或私人标本馆中。已根据所调查分类群原产国的文献对分类群进行了鉴定，而命名则遵循当前的国际参考文献。报告了106个分类群的最新情况。特别是，在117条新记录中，89条是首次记录，27条是状态变化，还有1条是灭绝记录。报告了意大利外来植物区系的7个新分类群，其中2个是欧洲新发现的。记录数量最多的行政区是卡拉布里亚（48条）、撒丁岛（17条）和西西里岛（15条）。所调查的分类群中有5个首次被视为意大利领土上的入侵外来物种。这项工作提供的原始结果数量不多，但其重要性超过了数据本身的重要性，这证明了植物区系调查至今仍是拓宽当前关于外来分类群及其动态知识的最有效工具之一。
