The typical variety, var. regalis, is found in the Old Word (Fernald 1930). Treating the American taxon, var. spectabilis, as a distinct species has also been advocated based on analysis of DNA which suggests var. spectabilis is more closely related to O. japonica (Metzgar et al. 2008; Tsutsumi et al. 2011; Arana et al. 2015; Schneider et al. 2015).
