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.
