Discussion | N. N. Tzvelev (1983) recognized six subspecies (including two in North America) within Plantago canescens; North American material is not segregated as such here. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.) |
