– New area record for this taxon, identified by SEM study of the seeds. The native range of this taxon is the Mediterranean; it is found in Europe, N Africa and W Asia ( Amini Rad & al. 2017; POWO 2023b). Recently, Portulaca trituberculata was noted from continental Ukraine ( Bulakh & al. 2020). Because this taxon is characterized as native in the regions adjacent to Crimea, and it has been widely distributed on the peninsula for a long time, mostly in natural and semi-natural habitats, it can obviously be considered a native species there.
