New synonyms in Celastraceae toward an update of the flora of Brazil

This paper proposes nine new synonyms for seven Brazilian taxa from two genera: Monteverdia and Plenckia (Celastroideae). This proposal is a preliminary step in the Celastraceae treatment for the ongoing “Flora do Brasil 2020” project. Most of the names discussed here had been neglected in literature and are absent in available taxonomic revisions, with some being discussed for the first time after the publication.

Additionally, lectotypes for seven names are designated here.
