Discussion | Plantago lanceolata is known from historic collections in Manitoba and Saskatchewan. The name Plantago altissima Linnaeus sometimes has been misapplied to North American plants of P. lanceolata. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Three varieties of Plantago media have been recognized in western Europe. It is not clear how names of those varieties apply to P. media in eastern Europe and North America. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
