Portulaca daninii Galasso & al.

(≡ Portulaca tuberculata (Danin & H. G. Baker) Danin 2006 [non Portulaca tuberculata León 1950] ≡ Portulaca oleracea subsp. tuberculata Danin & H. G. Baker) – Fig. 7C, D .

A Cm: Crimea: Sudak, S slope, 31 Jul 1886, Zelenetskiy (YALT); Dzhankoyskiy district, Tarkhan-Sunak, 17 Aug 1897, collector unknown (YALT); Feodosiyskiy district, Vladislavovskiy site of grain farm, Bashta (melon field), area between Novo-Pokrovka village and Seit-Asan village, 22 Aug 1930, Deutsch (Doych) (YALT). – New area record for this taxon, identified by SEM study of the seeds. Its native range is Tropical America. It has recently been noted from Ukraine ( Bulakh & al. 2020, as Portulaca tuberculata ) and Poland ( Bulakh & al. 2022). Only ancient specimens of this species have been discovered in Crimea. Perhaps it has disappeared by now; therefore it qualifies as a casual alien.
