octogonum

Octogonum is a genus name that has appeared in various taxonomic writings but is not presently established as a widely accepted, unambiguous genus in modern classifications. The term is Latin in form, combining octo- meaning eight with gonum, a suffix often associated with angle or corner features, suggesting that some author or specimen once highlighted an eight-angled morphology. Because the name has been used by different authors for different organisms and without a consistent circumscription, its exact application has varied over time and across groups.

In botanical and other biological literature, Octogonum has been proposed or employed at different periods, and some usages have been reinterpreted, synonymized, or abandoned as classifications changed. As a result, there is no single, universally accepted taxon currently carrying the name Octogonum in major, up-to-date databases. The status of the name is best described as historical or ambiguous rather than as a valid, modernly recognized genus.

To determine whether any valid and current use exists, researchers are advised to consult authoritative nomenclatural databases. For plants, databases such as IPNI or Tropicos; for fungi, Index Fungorum; and for animals, ZooBank provide up-to-date records on published names and their accepted status. In the absence of a clear, current designation, Octogonum should be treated as a historical synonym or as a nomenclatural reference rather than as a standing taxon.
