Discussion

Subspecies intermedia (Gilibert) Lange is often accepted by European botanists as a separate species, Plantago uliginosa F. W. Schmidt. Observations suggest that plants referable to this taxon may occur in the United States; it has been reported from the New England states (A. Haines 2011). Subspecies intermedia is distinguished by more abundant (11–35) and smaller (0.8–1 mm) seeds, ascending spikes, ovoid fruits, and elliptic or lanceolate leaf blades. Without detailed morphologic and genetic investigations of North American plants similar to the study of European plants by M. Morgan-Richards and K. Wolff (1999), 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.
