Synonymies and typification of the Rhamnaceae of Brazil

Abstract

In the course of preparing the taxonomic revision of the Rhamnaceae of Brazil for the Catalogue of Plants and Fungi of Brazil, several problems related to typification were detected. Taxonomic observations and nomenclatural notes are here reported based on the analysis of type material, as well as classic and recent collections, in 63 herbaria in Brazil and abroad, together with analyses of virtual herbaria. Types were sought, the majority of which were located and studied. Eleven synonymies, 37 lectotypes and one neotype are designated and defined for seven genera in the family.
