On the original material of Senecio dombeyanus (Compositae), an interesting case linking the herbaria G, MA, and P

Abstract

The name Senecio dombeyanus DC. has disparately been treated over time depending on the authors because of the uncertainty concerning the provenance of the original material, which was collected during the “Expedición Botánica al Virreinato del Perú”, namely by Joseph Dombey. This issue is clarified here, as well as its implications on the Bolivian flora. Furthermore, a lectotype is designated for the name S. cremeiflorus Mattf., and the name S. amplus J.Rémy is synonymized with S. smithii DC.
