i was wondering what are the latest scientific definitions to current taxonomic ranks. for example, when i can say this taxon is family, or subfamily or genus, … etc. I found a brief explanation regarding ranks between species to form on KEW website. However, other ranks I’m not sure i have the latest updates.
If you are looking for the formal definitions, they are in the 2018 International Code of Nomenclature for Algae, Fungi, and Plants (ICN), Division II, Chapter 1 (here).
