Invalidly published names inJanchen's “Catalogus florae Austriae”: Survey, analysis, and notes

Abstract

Names of species and subspecies fromJanchen's Catalogus were revised with regard to their validity; invalidly published names were compiled in a commented list of 120 names. About sixty of them were analyzed at length from nomenclatural and taxonomical viewpoints. The cause of the invalidity of these names were discussed; omission of citations of basionyms to proposals of new nomenclatural combinations is the main reason for the invalidity ofJanchen's names. Taxonomic reclassifications and nomenclatural revisions resulted in 23 new nomenclatural combinations, five of these proposals representing direct validations ofJanchen's invalidly published names. Some more general problems of nomenclature are discussed: indirect validation of invalidly published names; omission of infraspecific homonymy; the correctness and necessity to attach neglected authors' names to the names of plants based on those names distinctly taken over from such authors; problems of autonyms in the ICBN Code. The use of the category “convarietas” in cultivated plants (instead of subspecies) is emphasized. Names validated byJanchen himself in his paper of 1959 should be used with this publication place instead of their invalid publication in the Catalogus. Some propositions for future research by other authors are also added.
