It includes new records, confirmations, exclusions, and status changes for Italy or for Italian administrative regions. Nomenclatural and distribution updates published elsewhere are provided as Suppl. material 1. Keywords Alien species, floristic data, Italy, nomenclature How to contribute The text for the new records should be submitted electronically to Lorenzo Lastrucci (lorenzo.lastrucci@unifi.it). The corresponding specimen along with its scan or photograph has to be sent to FI Herbarium: Museo di Storia Naturale (Botanica), Sistema Museale di Ateneo, Via G. La Pira 4, 50121 Firenze (Italy). Those texts concerning nomenclatural novelties (typifications only for accepted names), status changes, exclusions, and confirmations should be submitted electronically to Gabriele Galasso (gabriele.galasso@ comune.milano.it). Each text should be within 1,000 characters (spaces included). Floristic records Acer negundo L. (Sapindaceae) + (INV) TOS. – Status change from naturalized to invasive alien for the flora of Toscana. The presence of Acer negundo is increasingly common in disturbed areas of Toscana. Numerous individuals colonize urban areas and roadsides (Peruzzi and Bedini 2022+). From observations made in 2020 in the provinces of Siena and Arezzo, we noticed that in some areas with a strong disturbance the species grows abundant, sometimes in dense stands. In Chiusi [(Siena), fraz. Montallese, lungo la strada SP326, WGS84: 43.052790°N, 11.920611°E, margini stradali e ambienti ruderali, 255 m, 17 September 2021, T. Fiaschi, E. Fanfarillo (SIENA)] and other localities (e.g., Monteriggioni (Siena), WGS84: 43.392968°N, 11.217782°E), we observed abundant, fructifying adult individuals and seedlings. We therefore propose the change of status from naturalized to invasive. C. Angiolini, E. Fanfarillo, T. Fiaschi Allium tuberosum Rottler ex Spreng.

Tosetto (FI). – Casual alien species new for the flora of Italy (Veneto). This species was identified according to Liu and Phillips (2006). The plant is cultivated in China for food use of the young shoots and rhizomes when infected by the fungus Ustilago esculenta Henn. (Basidiomycota), which renders the indicated parts edible and inhibits the normal development of the synflorescence. Since the plants found do not bloom, their presence at the site is almost certainly related to this use. E. Banfi, L. Tosetto, R.R. Masin, R.
