Mosyakin, S.L. | Mosyakin, A.S.
Noteworthy records of 11 alien plant species in Kyiv City and Kyiv Region made mainly in 2020 are discussed. In particular, new localities of the following taxa are reported: Amaranthus spinosus, Artemisia tournefortiana, Chenopodium ucrainicum, Celastrus orbiculatus, Datura innoxia, Dysphania ambrosioides, Erechtites hieraciifolius, Mesembryanthemum ×vascosilvae (M. cordifolium × M. haeckelianum; recently described as Aptenia ×vascosilvae and reported here for the first time for Ukraine; earlier this ornamental hybrid was misidentified as Aptenia cordifolia), Parietaria officinalis, Phytolacca americana, Thladiantha dubia. The presence in Ukraine of several additional species, such as Datura wrightii and Phytolacca acinosa s.l. (incl. P. esculenta), that may occur as escaped near places of their cultivation, is reported; these species may be confused with D. innoxia and P. americana, respectively. The growing role of alien plants escaped from cultivation (ergasiophytes) in the present-day processes of formation of the alien flora of Ukraine is emphasized.
