There is an earlier tag synonym suggestion for taxonomy <- nomenclature. However, I see nomenclature as a more general term, for dealing with all sorts of naming/classification issues, while taxonomy is only dealing with the naming of species and other taxa. I have suggested a wiki edit to clarify this: https://biology.stackexchange.com/tags/nomenclature/info.
What are your opinions? Should we use both nomenclature and taxonomy or only taxonomy.
