Discussion | 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.) |
Plantago firma has been known in California, especially in Marin County, since at least 1896, but the most recent collection known was made in 1957. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
