Taxonomic synonyms: meaning, types, and importance in biological nomenclature
Taxonomic synonyms are different scientific names that refer to the same taxon. This article explains types of synonyms, rules in botany and zoology, common examples, and why synonyms matter for research and biodiversity records.
Overview
In biological classification, a synonym is an alternative scientific name that has been applied to the same taxon (species, genus, etc.). Unlike ordinary language synonyms, taxonomic synonyms arise from changes in classification, differing interpretations of specimens, or revisions of naming rules. For a short introduction see synonyms in taxonomy and how they differ from non‑scientific everyday synonyms.

How synonyms occur and the rules that govern them
Names become synonymous for several reasons: two authors may independently describe the same organism under different names; a species may be moved to a different genus creating a new combination; or later study may show two named taxa are the same biological entity. Formal codes govern which name should be used. Botanical names follow the International Code of Nomenclature (botany), while zoological names follow the International Code of Zoological Nomenclature (zoology).
Common types of taxonomic synonyms
- Objective (homotypic): names based on the same type specimen or nomenclatural type — different combinations but the same original material.
- Subjective (heterotypic): names based on different type specimens later interpreted as referring to the same taxon.
- Senior and junior synonyms: the earliest published name normally has priority (senior), while later names are junior synonyms and are usually not adopted unless conserved.
- Replacement names (nomen novum): new names created to replace unavailable or illegitimate ones.
Illustrative examples
Well known examples help show how synonyms appear in practice. Domestic cats have been named in various ways, such as Felis silvestris catus and Felis catus, illustrating different combinations and rank treatments (see cat names). In plants, the palm originally described as Daemonorops draco has also been listed as Calamus draco, where one name is treated as the accepted or "correct name" and the other as a synonym (palm example).
Why synonyms matter
Synonyms affect literature searches, biodiversity inventories, conservation law, and databases. Taxonomic revisions clarify which name should be used, but older names often persist in museum labels and publications. To avoid confusion, check authoritative checklists and taxonomic databases that record synonymy and the currently accepted name.
Practical notes and distinctions
Synonyms are distinct from homonyms (the same name applied to different taxa) and differ between disciplines by terminology and procedure. When using scientific names, include author citations and consult current taxonomic treatments to ensure the accepted name is applied and synonyms are recognized.
Questions and answers
Q: What are synonyms in taxonomy?
A: Synonyms in taxonomy are two or more names for the same thing in a scientific classification.
Q: Can you give an example of synonyms in taxonomy?
A: Yes, for example, the cat has a few scientific names like Felis silvestris catus, Felis catus, and Felis catus domestica.
Q: What is the special meaning of the word "synonym" in botany?
A: In botany, the word "synonym" refers to the other names for a species that are not the correct name. There is one "correct name," and the other names are synonyms.
Q: Can you give an example of the correct name and synonym in botany?
A: Yes, for example, Daemonorops draco is the correct name for a species of palm trees, while Calamus draco is a synonym for the same species.
Q: In zoology, what is the difference between "valid name" and "junior synonyms"?
A: In zoology, there is one "valid name" for a species, and the others are "junior synonyms" that were previously used but are no longer recognized as the correct name.
Q: Are synonyms in taxonomy only used in scientific fields?
A: Yes, synonyms in taxonomy are only used in scientific fields like botany and zoology as they refer to scientific names for species.
Q: Why are synonyms important in taxonomy?
A: Synonyms are important in taxonomy to avoid confusion and provide a system of consistent and accurate scientific naming for species.
