Cynanchum Linnaeus. Subfamily: Asclepiadoideae. Common name: Swallow-wort.
A genus of about 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).
