Epilobium latifolium
I'm going to take a chance here and assume, for the time being, that Epilobium latifolium (now Chamerion latifolium) is still a valid one to kick off this forum... ? (Since "Zauchneria" [lately renamed as Epilobium] is listed here as such, I think I'm on solid footing (?), but if not, moderators, please feel free to move or nuke this posting! :))
