Discussion | The circumscription of Plantago patagonica is treated here in accordance with K. Rahn (1978). The phenotypic plasticity of it does not allow varieties or subspecies to be recognized. Plants recognized in other floras as P. purshii (for example, Flora of Indiana and Flora of New Mexico) are referable to either P. aristata or P. patagonica (Rahn).
