As part of the ongoing studies of the genus Polycarpon (Caryophyllaceae) andthe preparation of its treatment for the Argentinian Flora, we here present a taxonomic noteconcerning the identity of the name P. apurense. A specimen preserved at P is designated as thelectotype of this name. Its identity was discussed and the synonymy with P. prostratum, recurringin the literature, was discarded on the basis of its habit and leaf shape and size. A nomenclaturalchange (i.e. P. tetraphyllum subsp. apurense) is proposed here on the basis of the currentconcept in the genus Polycarpon. Concerning the distribution of this taxon, it is excluded fromBrazil and Uruguay and its presence in Peru is uncertain.
