*Verbena officinalis Linnaeus. European Vervain, Juno’s Tears, Herb-of-the-cross. Phen: Jun-Oct. Hab: Disturbed areas, riverbanks. Dist: Native of Europe.

Origin/Endemic status: Europe

Other Comments: The enigmatic V. riparia is represented by a few collections, and the taxonomic status of the taxon is unclear; it probably represents an unusual form of V. officinalis. Jiménez-Mejías & Naczi (2019) clarify its typification and mention that if what Small and Heller believed to be a separate and native species proves to be so, it will need a new name.
