Vincetoxicum rossicum

Vincetoxicum rossicum (Kleopow) Barbar. (syn.: Antitoxicum rossicum (Kleopow) Pobed., Cynanchum rossicum (Kleopow) Borhidi) (former USSR) – An exceptional alien, recorded only once in Wechelderzande in 1965, without obvious vector of introduction (probably an escape from cultivation; see also Markgraf 1971). Vincetoxicum rossicum behaves like a noxious environmental weed in several parts of the world (see for instance DiTommaso & al. 2005, Kricsfalusy & Miller 2010).
