Legend

A bold capital letter after a taxon name indicates its presence in Metropolitan France, according to TAXREF:

P: Present, E: Endemic, S: Subendemic, C: Cryptogenic, I: Introduced, J: Introduced invasive, M: Introduced, not established, B: Occasional presence, D: Doubtful, Q: Erroneously mentioned, A: Absent, X: Extinct, Z: Endemic extinct, Y: Introduced extinct, W: Regionally extinct

A taxon name in parentheses indicates that a synonym was used as the accepted name in TAXREF, because accepted names do not perfectly overlap between TAXREF and POWO. Minor discrepancies - such as changes in author citation, spelling variants, and differences in publication date - are ignored.
