Notes

Was included in Cynanchum L., but more closely related to Tylophora R.Br. (1810) and here is treated as congeneric with Vincetoxicum (1776), which has precedence under ICBN.

Vincetoxicum Walter, Flora Caroliniana: 13, 104. 1788, nom. illeg. is a later homonym and synonymous to Gonolobus

Vincetoxicum is a genus of plants in the family Apocynaceae. Although the species in Vincetoxicum have sometimes been included in Cynanchum,[1][2] chemical and molecular evidence shows that Vincetoxicum is more closely related to Tylophora.[3][4]
