refer to something about biology itself; for instance, not a branch of biology; are broadly applicable terms, not specific to a small subset of organisms; do not fit well into any other more specific existing terminology category; Anatomical terms are not included here and appear in sub-categories of the main Anatomy category.
Although the basic principles are fairly similar, the treatment of synonyms in botanical nomenclature differs in detail and terminology from zoological nomenclature, where the correct name is included among synonyms, although as first among equals it is the "senior synonym": Synonyms in botany are equivalent to "junior synonyms" in zoology.
