Discussion | Plantago afra is known in Massachusetts from a single collection made in 1927 in Worcester County. Plantago psyllium Linnaeus (1762, not 1753), a rejected name, and P. indica Linnaeus are misapplied names that pertain here. Plantago squalida Salisbury is an illegitimate name that pertains here.

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.) |
