• 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. Whether taxa can have "members" is debatable. See the LPSN phylogeny page for details. Publication: Göker M.
