Taxonomic novelties in Varronia (Cordiaceae): Rediscovery of V. neowediana and lectotypification of V. macrocephala

Abstract

Varronia neowediana was rediscovered after a lapse of 176 years since its original publication. Here we provide the first illustration and a detailed description of this species, as well as a distribution map, and comments on its conservation and related species. The typification of Varronia macrocephala is also discussed, and a lectotype is designated.
