• Notes:
  • 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. Using the term "phylogenetic data" (or equivalent) for sequence data is not advocated.
