The names printed in bold-face italics, and all combinations based on these names, are ruled as rejected under Art. 56, and none is to be used. The rejected names are arranged in alphabetical sequence, irrespective of rank, within each major group. Cross-references to the rejected basionyms are provided under some combinations based on them.

The rejected names are neither illegitimate nor invalid (Art. 6). Later homonyms of a rejected name (Art. 53), and names illegitimate because of inclusion of the type of a subsequently rejected name (Art. 52), are not to be used unless they are conserved.
