Geographic distributions and chromosome numbers of the extant diploid and tetraploid Panax species. The diploid species P. trifolius shows overlapped distribution with the tetraploid P. quinquefolius. The P. bipinnatifidus species complex covers the distribution ranges of P. notoginseng, P. stipuleanatus and P. pseudoginseng. Star, sampling locations of the species P. ginseng and P. quinquefolius in Jilin province of China; Circle, sampling location of P. bipinnatifidus species complex in Sichuan province of China; Triangle, sampling locations of P. notoginseng, P. stipuleanatus and P. bipinnatifidus species complex in Yunnan province of China. The original map was downloaded from Wikimedia Commons(https://commons.wikimedia.org/wiki/File:Map_of_the_Pacific_region.svg?uselang=zh-cn). The information of geographic distributions of Panax species was retrieved from the Natural Resources Conservation Service of USDA (www.plants.usda.gov) and Flora of China (www.efloras.org)
