The nomenclature of eight species of Peruvian endemic plants from six genera (Arenaria L., Calceolaria L., Erigeron L., Pycnophyllum J. Rémy, Pycnophyllopsis Skottsb., Schizotrichia Benth.) is reviewed, and the corresponding changes are proposed. Additionally, lectotypes for Pycnophyllum peruvianum Muschl. and P. macrophyllum Muschl. are selected, and conservation assessments are provided for all species.
