Diagnostic Characteristics:
Perennial herb that is scapose (the flowering stem and leaves arising from the rhizome. The leaves are ternate 9divided into three) and the leaflets are pinnately divided into 305 segments which are acuminate and finely serrate. The lateral leaflets are assymetric at the base. Fruit is black.

Management:
Disturbance such as ATV trails, timber removal or any activity that results in increased erosion and weed invasion will be detrimental.

Global Range:
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.
