Table of equivalence of nomenclatural terms used in the Draft BioCode and in the current biological Codes (abbreviations explained below; references in text). The concepts covered by terms given as equivalent are not always exactly the same (e.g., nomenclatural superfluity, an obstacle to legitimacy under the ICBN, is unknown under the BC and ICZN).

BC = International code of nomenclature of bacteria (Lapage et al., Washington, 1992)
ICBN = International code of botanical nomenclature (Tokyo Code) (Greuter et al., Regnum Veg. 131. 1994)
ICNCP = International code of nomenclature for cultivated plants - 1995 (Trehane et al., Regnum Veg. 133. 1995)
ICZN = International code of zoological nomenclature (Ride et al., London, 1985)

1Although the Bacteriological Code defines "effectively published" with the meaning of "published" in the BioCode, the term is commonly used to imply "published in a form eligible for registration".
