Background and aims

: Sapindaceae is represented in Argentina by 15 native genera with 45 species in total. In the context of the taxonomic treatment of this family for the Flora Argentina project, many names are identified that need to be typified in order to stabilize their nomenclature, as well as the clarification of classic-type material and the proposal of new synonyms. All these names belong to genera Allophylus, Athyana, Cardiospermum, Cupania, Diatenopteryx, Diplokeleba, Dodonaea, Guindilla, Paullinia, Serjania and Thinouia.

M&M

: The nomenclatural treatment is based on the analysis of protologues, plus the study of the type-material either physical or through online images. Typification is carried out according to the International Code of Nomenclature for Algae, Fungi and Plants.

Results & Conclusions

: Lectotypes are designated for 39 taxa of Sapindaceae linked to the Flora of Argentina. The holotypes of three species are clarified. Two new synonyms are proposed.
