Artemisia verlotiorum (Asteraceae) in the continental part of Ukraine: now in Kyiv

Abstract

Colonies of Artemisia verlotiorum (Asteraceae), an alien species of East Asian origin now widespread in many countries of the world, were found in 2018 in Kyiv in the Syrets Arboretum (Syretskiy Dendropark) and in a nearby abandoned plant nursery and greenhouses. At present, three clonal colonies have been revealed. Most probably rhizomes of that species were initially introduced to Kyiv with soil and/or imported trees and/or shrubs. However, one colony (along the wall of the administrative building of the arboretum) most probably emerged from seeds dispersed by wind from the main (supposedly initial) colony in the abandoned nursery. Before our find in Kyiv, A. verlotiorum was reliably known in Ukraine in Crimea (reported since the 1920s), Transcarpathia, and from Lviv (recent records, to be discussed in detail in a forthcoming article). Most probably A. verlotiorum is spreading in Eastern Europe mainly by rhizome fragments with soil and plant material. Other alien taxa of the Artemisia vulgaris group (especially A. umbrosa and A. argyi) occur in Ukraine mainly as "railroad" plants.

Diagnostic micromorphological features of leaf surface of selected species of the genus Artemisia L. (Asteraceae)

“…The two last invasive species, A. argyi and A. verlotiorum, are of particular interest. They have appeared relatively recently in Ukraine and in recent decades have shown a tendency to expand into natural phytocenoses (Mosyakin et al, 2019 and the references therein). Moreover, the dry raw material of A. argyi is morphologically similar to A. absinthium and so can potentially occur as an impurity in the raw material of the latter species.…”

New floristic finds in the Forest-Steppe part of Zhytomyr Region

“…Artemisia umbrosa (Turcz. ex (Mosyakin, 1990), нині відомі ще його одиничні місцезнаходження в правобережній частині Києва, Донецькій, Закарпатській, Київській, Львівській, Полтавській, Херсонській і Чернівецькій областях та АР Крим (Boiko, 2012;Mosyakin et al, 2018Mosyakin et al, , 2019Davydov, 2021). Місцезростання в Україні приурочені до залізниць, а також інших рудеральних біотопів на узбіччях доріг і в населених пунктах.…”

Genome size confirms the presence of Artemisiaverlotiorum (Asteraceae) in Lebanon

“…However, these claims are in part erroneous, and result from the ongoing confusion of A. verlotiorum with other representatives of Artemisia L. sect. Artemisia (Verloove, 2013 1 ; Mosyakin et al, 2018;Mosyakin et al, 2019).…”
