Discussion

While considering the proposal made by W. L. Applequist (2006) to reject Plantago psyllium, the Nomenclature Committee for Vascular Plants also decided that P. indica is a legitimate name (R. K. Brummitt 2009). A. B. Doweld and A. Shipunov (2017) published a proposal to reject P. indica in favor of P. arenaria. That proposal awaits a decision by that committee.

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.
