Argentina, Bolivia (Santa Cruz), Brazil, Paraguay. Australia, Hong Kong. Rapidly becoming a pantropical weed.

Note: Veldkamp (1999), at some length, noted that Grisebachs name was a later homonym of Schultz Bipontinus combination (Schultz Bipontinus 1866: 258) of a de Candolle name 樉 Mikania clematidea Wall. ex DC. (de Candolle, 1836: 191). Effectively, King & Robinson (1970: 194) had provided a new name for Grisebachs plant within Praxelis. Veldkamp also noted that the two varietal names were comb. incorr.

Note: Eupatorium erythrolepis Sch.Bip., a nom. nud., is based on Madon 261. However, this name is equated with Lorentzianthus viscidus (Hook. & Arn.) R. M. King & H. Rob., although clearly the material is of a Praxelis.
