In the process of compiling a flora for Montana (Lesica, 2012, 2022), we came to realize that many published nomenclatural changes are only weakly supported by the data presented which has often been based on recent findings in the field of molecular evolution. In this essay we attempt to present a summary of the reasons why taxonomic changes may be less than robust and our guidelines for accepting newly proposed nomenclature that we attempted to follow in our work.
