Abstract

IAMONICO, Duilio  and  ZANOTTI, Christian A.. On the taxonomical identity of the South American Polycarpon apurense (Caryophyllaceae) with clarification on its distribution. Bonplandia [online]. 2022, vol.31, n.1, pp.89-95. ISSN 0524-0476.  http://dx.doi.org/10.30972/bon.3115824..

As part of the ongoing studies of the genusPolycarpon(Caryophyllaceae) and the preparation of its treatment for the Argentinian Flora, we here present a taxonomic note concerning the identity of the nameP. apurense. A specimen preserved at P is designated as the lectotype of this name. Its identity was discussed and the synonymy withP. prostratum, recurring in the literature, was discarded on the basis of its habit and leaf shape and size. A nomenclatural change (i.e.P. tetraphyllumsubsp.apurense) is proposed here on the basis of the current concept in the genusPolycarpon. Concerning the distribution of this taxon, it is excluded from Brazil and Uruguay and its presence in Peru is uncertain.
