In this paper, based on recent and old bibliography and some own field observations, 69 more taxa (neophytes) are added to the catalogue of the exotic (or xenophytic) naturalised or subspontaneous vascular flora of continental Portugal, which includes now 841 taxa (species, subspecies, varieties and hybrids), a growth corresponding to more than 8.9% of the previous total number of 772 taxa, since our last reassessment, published in 2018, and our earlier surveys.
