“…Recent work on the phylogenetic relationships, character-associated diversification, and taxonomy of Asarum (Gaddy, 2011;Sinn, 2015;Sinn et al, 2015aSinn et al, , 2015b have sparked a renewed regional interest (Keener and Davenport, 2015;Weakley, 2015;Diamond, 2016) in the rank-level designations of the infrageneric categories established by Araki (1937Araki ( , 1953, Cheng and Yang (1983), Kelly (1997Kelly ( , 1998Kelly ( , 2001), Sugawara (2006), and Sinn et al (2015a).
