Discussion

Variety cusickiana varies in morphology and habitat. Individuals from Oregon and Idaho have narrowly lanceolate to almost oblong leaf blades, usually with little dentation. Scapes begin flowering when short and elongate throughout anthesis to overtop the basal rosette of leaves. Degree of available moisture appears to affect vegetative morphology in this variety, with consistently moist sites containing more robust individuals than habitats with ephemeral moisture. Number of flowers is similarly affected. This phenotypic plasticity has resulted in additional names suggested for both Oregon and Idaho populations, none yet supported by clear genetic or ecological distinction.
