Dellaria

Dellaria is a term that has appeared in historical scientific literature as a proposed genus name in botany and mycology. It is not currently listed as a valid genus in major taxonomic databases, and its precise circumscription varies between sources.

Taxonomic status has been unstable; some authors treated Dellaria as a synonym of another genus, while others used it as a nomenclatural placeholder in early descriptions. The lack of consistent usage has led to confusion about what organisms, if any, should be included under the name.

In practice, Dellaria often appears in older publications, and modern treatments typically suppress it in favor of more widely accepted genera. When encountered in literature, the name should be interpreted with attention to the cited authority and date, as later works may have reassessed the taxonomic identity.

The name appears to be a constructed Latinized term without a universally adopted meaning across disciplines; its assignment to a taxon reflects the historical development of taxonomy more than a lasting, clearly defined natural-group concept. As a result, Dellaria is best treated as a historical or ambiguous term requiring careful source checking to determine its intended reference in a given text.
