Abstract
Caragana and Calophaca are two closely related genera in the family Fabaceae. Recently, Calophaca was merged into Caragana, treating it as Caragana sect. Calophaca. This classification was further supported by molecular phylogenetic evidence. However, some of the resulting new combinations are considered illegitimate homonyms under the International Code of Nomenclature for algae, fungi, and plants (ICN), due to overlap with pre-existing names within Caragana. Therefore, these taxa require renaming or replacement with available epithets. In this study, we review the new combinations within Caragana and propose five replacement names to resolve the nomenclatural conflicts, along with two new combinations.
