Cynanchum Linnaeus. Swallow-wort.
A genus of about 200-300 species, herbaceous vines and lianas, primarily of tropical and warm temperate portions of the New World and Old World (Endress et al. 2018). Ampelamus was retained as a genus by Liede (1997a), but later results suggest that it is not distinct from some other portions of Cynanchum (Liede & Täuber 2002). However, Cynanchum itself is strongly polyphyletic and is being broken up; further taxonomic and nomenclatural changes are likely. C. laeve will probably remain in Cynanchum s.s. (which is primarily Old World in distribution).
