  • 😢 The terminology used by the authors is in line with many other taxonomic studies and does not negatively affect their main results; some improvements may nevertheless be possible. Contrasting the term "chemotaxonomic" with "phenotypic" is not recommended. The usage of the term "coherent taxon" (or equivalent) is cautioned against. See the LPSN phylogeny page for details.
