Portulaca sardoa Danin & al. – Fig. 9E, F.

A Cm: Crimea: Yalta , bus station, 44°30'42''N, 34°10'14''E, 45 m, flowerbed, 22 Dec 2019, Ryff (YALT); ibid., 44°30'41''N, 34°10'11''E, 45 m, flowerpot, 28 Sep 2021, Ryff (YALT). – This taxon is given only for Sardinia and Corsica ( Danin & al. 2012, 2016; POWO 2023b). In Crimea, Portulaca sardoa has been found in a single locality so far. Probably it was accidentally introduced from Italy with a soil mixture or planting material for ornamental plants.
