Gregoriae

Gregoriae is a Latin-specific epithet used in the scientific names of organisms to honor a person named Gregoria. It is not a genus or a standalone taxon. When a new species is named after a woman named Gregoria, the epithet gregoriae is typically appended to the genus name to form the binomial name.

Etymology and form: The epithet gregoriae is the genitive form of the female given name Gregoria, indicating "of Gregoria." In Latin, patronyms for female honorees commonly end with -ae. This form is used across taxonomic groups and does not denote a particular taxon by itself.

Usage and nomenclatural rules: In both botanical nomenclature (ICN) and zoological nomenclature (ICZN), patronyms are permissible and are formed as proper Latin genitives. The ending -ae signals a female honoree; for male honorees, endings such as -i or -ii are used. The epithet is treated as part of the species name and is published together with a description and the author's citation. In most cases, gregoriae remains constant regardless of the genus to which it is attached.

Scope and examples: There is no standalone taxon named "gregoriae." Instead, gregoriae occurs as a specific epithet in combination with various genus names to honor individual Gregorias—most commonly women named Gregoria. The epithet appears across diverse groups, including plants, animals, and fungi, as part of patronymic naming practices.
