Selon FNAms:
Subspecies intermedia (de Candolle) Arcangeli is often accepted by European botanists as a separate species, Plantago uliginosa F. W. Schmidt. Observations suggest that plants referable to this taxon occur in the United States. Subspecies intermedia is distinguished by more abundant (11--35) and smaller (0.8--1 mm) seeds, ascending spikes, ovoid capsules, and elliptic or lanceolate leaves. However, without detailed morphologic and genetic investigations of North American plants, it is not possible to draw any conclusions about the status and distribution of this or any other possible infraspecific taxa of P. major in North America.
