Leafy Willowherb (Epilobium ravenii Hoch & Gandhi)

Also classified as Epilobium foliosum (Torr. & A. Gray) Suksd..

Older sources refer to this species as Epilobium foliosum (Torr. & A. Gray) Suksd. (1900), but this name has been deemed illegitimate, probably because the name was already used (1841 and 1842) to refer to specimens which have now been deemed to belong to other species. However, this renaming is recent (2022) and most sources still refer to this taxon as Epilobium foliosum (Torr. & A. Gray) Suksd. In this case the specification of author is important because there name Epilobium foliosum has been used by five different authors to refer to different specimens which refer to four different species.
