Oncidium longicornu

The term Oncidium longicornu does not appear in major botanical references, taxonomic databases, or peer‑reviewed literature as a formally recognized species or synonym within the orchid genus Oncidium. Consequently, it cannot be confirmed as an established scientific name.

Limited Discussion

• Etymology: The epithet longicornu derives from Latin roots: longi‑ meaning “long” and cornu meaning “horn.” In botanical nomenclature, such an epithet might refer to a morphological feature—perhaps elongated, horn‑like structures on the flower or plant.

• Possible Confusion: The name may be a misspelling or variant of a legitimate Oncidium species, such as Oncidium longicornatum or a similarly named taxon. Without a verifiable source, any association remains speculative.

• Contextual Usage: If encountered in horticultural forums, plant lists, or informal contexts, the name could represent an unpublished cultivar, a provisional label, or a typographical error.

Conclusion: No reliable encyclopedic information is available for Oncidium longicornu; the term is not widely recognized in the scientific community.
