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.) |
According to J. Burkhalter (pers. comm.), Plantago floccosa is well established in northwestern Florida near the border with Alabama. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
