- species have a name composed of two names, a "binomen": a generic name and a specific name. No other rank can have a name composed of two names:
- subspecies have a name composed of three names, a "trinomen": generic name, specific name, subspecific name,
- taxa at a rank above species have a name composed of one name, a "uninominal name".
The "Principle of binominal nomenclature" is an important principle in the ICZN.
In botanical nomenclature, the equivalent for "binominal nomenclature" is "binary nomenclature" (or sometimes "binomial nomenclature").
