Species: Aralia nudicaulis

Throughout much of Canada, and in the U.S. from Maine south to the mountains of northern Georgia, and northwestwards to Washington (USDA-NRCS 1999). Ten extant locations are known from Missouri (Missouri Department of Conservation). It is reported from four counties in Kentucky (Kentucky Natural Heritage Program). It is found in all counties in Maine (Maine Natural Areas Program). In Indiana this species is found throughout the northern part of the state and in one location in the southeast (Indiana Natural Heritage Data Center). It is disjunct in Colorado and Nebraska, where it survives in limited mesic habitats as a Pleistocene relict (Weber and Wittmann 1996, Nebraska Natural Heritage Program). In Manitoba, it occurs northwards to near latitude 57 degrees 30 minutes (Manitoba Conservation Data Centre). A. nudicaulis is apparently restricted to North America.
