Ampelopsis glandulosa (Wallich) Momiyama (incl. A. brevipedunculata (Maximowicz) Trautvetter) (E As.) – A very rare escape from cultivation. In 2018 A. glandulosa was seen on two occasions: in an urban habitat close to the Botanic Garden of Liège and close to the arboretum in Kalmthout. In both localities it is likely that the species escaped from the collections; however, at least in Kalmthout it is not included in the official species catalogue. The species is dispersed by berry-eating birds and small mammals.
The infraspecific classification of Ampelopsis glandulosa is highly controversial. Five varieties were recognized by Chen & al. (2007). A broad concept of this taxon is followed here. In many horticultural reference works this species is down as A. brevipedunculata (e.g. Richardson 1997, De Koning & al. 2000, Roloff & Bärtels 2006).
Ampelopsis glandulosa has become naturalized and weedy in the eastern United States (Emerine 2011, Moore & Wen 2016).
