Nomenclatural notes in Begonia L. (Begoniaceae)

Abstract

As a result of a taxonomic study on the genus Begonia, 31 new synonyms are proposed, 13 lectotypes are designated and eight taxa are considered of uncertain identity. Eight invalid names are listed under Begonia fischeri Schrank, and the correct citation of the type material of Begonia raulinii Brade is presented. The rehabilitation of Begonia hammoniae Irmsch. is proposed, and nine taxa are excluded from the synonymy of various species as they are classified as cultivars or hybrids.
