– New area record for this taxon, identified by SEM study of the seeds. Its native range is the Mediterranean. The localities nearest to the Crimean populations are in continental S Ukraine, where it is noted as doubtfully naturalized (Dzhus & al. 2015; POWO 2023b), and in the E Mediterranean, where it is native. In Crimea, Portulaca rausii was found primarily in natural and semi-natural habitats only on the S coast, in the submediterranean zone. This suggests that it is a native species there.
