The correct answer is Monographs.

Key Points

  • A monograph is a detailed written study on a single specialized subject or an aspect of it.
  • In the context of taxonomy, a monograph provides comprehensive information on one taxon, such as a species or genus.
  • Monographs include descriptions, distributions, classifications, and other relevant biological information.
  • They are valuable references for researchers and scholars for in-depth study of the specific taxon.

Additional Information

  • Couplets: In taxonomy, couplets are used in dichotomous keys which consist of paired statements or questions to guide the identification of species.
  • Catalogs: Catalogs are systematic lists of items, often including brief descriptions, used for organizational purposes, but they can cover multiple taxa.
  • Manuals: Manuals provide instructions or guidelines, and in taxonomy, they can cover a wide range of taxa with identification keys and descriptions.
  • Monographs: As previously mentioned, monographs are detailed studies on a single taxon, providing extensive information on that particular group.
