Found in Del Norte County, California, in the Tolowa Dunes State Park, there is an Erysimum population that does not fit the species boundaries of E.concinnum Eastw., its current assigned name. A closely related species,  E. menziesi (Hook.) Wettst arguably better fits the morphology of the Tolowa Wallflower, with the caveat that it does not adequately depict the population. Because of the endemicity of the two aforementioned species and the Tolowa wallflower, correct taxonomic assessment and a clear definition of species boundaries are warranted. To evaluate the species boundaries and circumscription of the Tolowa wallflower, we would collect DNA samples from Erysimum from Monterey to Crescent City, California. Once the DNA has been extracted, we will use Angiosperm 353 to perform a high resolution phylogenetic analysis. Through our data collection, observations, and genetic study, we will test three hypotheses: 1) the current species name is correct for the Tolowa population, 2) the Tolowa population needs to be circumscribed to  E.menziesi and, 3) the Tolowa population is its own species. The last two outcomes would lead to a rare species classification, leading to increased funding for the conservation effort of the species and the Tolowa Dunes.
