A genus of about 74 species, herbs, shrubs, vines, and trees, primarily of e. North America, e. Asia, and se. Asia. Wen (1998) has suggested that A. nudicaulis may need to be removed from the genus Aralia in order to maintain both Aralia and Panax as monophyletic genera; more recent studies remain equivocal (Wen 2011) or agree with the removal (Zuo, Wen, & Zhou (2017).
