Of the Euphorbia dentata aggregate, both E. dentata and E. davidii have been reported from Europe. A revision of herbarium and published materials, however, indicates that only E. davidii can be confirmed in Europe. Although known in Europe since 1968, most records are from the 1990s. There are 46 known populations scattered throughout the continent, in Russia, Ukraine, Moldova, Romania, Bulgaria, Hungary, Italy, Belgium, Switzerland and France. Most populations are small and restricted to railway areas; however, the species can also invade agricultural fields. Due to its wide distribution, the growing number of recently established populations, and its invasive ability, special attention should be paid to changes in distribution and population sizes in Europe.
