Abstract

The collections made by the Bohemian botanist Thaddeus Haenke in America during the Malaspina Expedition (1789 - 1794) served Augustin-Pyramus de Candolle for describing numerous new species published in the Prodromus. Within the large Neotropical genus Senecio L. (Compositae), Candolle described 22 new taxa based on Haenke's material. The unfortunate mislabeling of some specimens led Candolle to provide inaccurate locotype indications, which entailed subsequent misinterpretations or uncertainty upon the respective species. Herein, we provide historical and taxonomic insights to clarify the provenance and taxonomic identity of the species S. adscendens DC., S. scrobicarioides DC., S. sternbergianus DC., and S. tridentatus DC., as well as a new circumscription for S. micropifolius DC. In terms of nomenclature, the aforementioned five names are lectotypified and four new synonyms are proposed.
