Notes: FNA3: "Populations of Trautvetteria caroliniensis in western North America have been distinguished from the eastern typical material as T. caroliniansis var. borealis (Hara) T. Shimizu [synonym: T. caroliniensis var. occidentalis (A. Gray) C.L. Hitchcock]. Asian populations, long treated as the distinct species T. japonica Siebold & Zuccarini, were most recently regarded (T. Shimizu 1981; M. Tamura 1991) as conspecific with the North American populations [as T. caroliniensis var. japonica (Siebold & Zuccarini) T. Shimizu]. Aside from geography, varietal differences seem rather arbitrary."
