Portulaca socotrana Domina & Raimondo

– Fig. 10A, B. A

Cm: Crimea: Gurzuf, Podvoyskogo str., 44°32'38''N, 34°16'48''E, 50 m, 2 Oct 2021, Ryff (YALT). – New area record for this taxon, identified by SEM study of the seeds. The taxon was previously considered endemic to the island of Socotra in the Indian Ocean ( Domina & Raimondo 2009), from where it was described, but was later noted in Tehran province in Iran ( Amini Rad & al. 2017). It was probably accidentally introduced to Crimea with imported building materials. Portulaca socotrana grows together with other alien species recently recorded in the region: Acalypha australis L. ( Yena 2012), Erigeron sumatrensis Retz. ( Raab-Straube & Raus 2017) and Sagina apetala Ard. ( Raab-Straube & Raus 2016) .
