Discussion | Plantago maritima has been reported from Utah; no specimen supporting that report has been found. Since the 1930s, when Plantago maritima was shown to have high levels of phenotypic plasticity (J. W. Gregor and J. M. S. Lang 1950), it usually has been accepted in a broad sense. That approach is followed here, with all dwarf and loose-flowered forms (such as P. borealis and P. decipiens, respectively) included under this name.
