Local to very local on wooded slopes in the southern counties. I have also found it on the wooded bank of Cedar Creek in Allen County. Outside the area indicated on the map, Coulter reported it from Kosciusko, Shelby, and Tippecanoe Counties, Higley & Raddin reported it from Pine, Lake County, and Schneck reported it from the Lower Wabash Valley and says: "Once common, now almost extinct." The plant is so conspicuous that if it was at all frequent I would have found it elsewhere in southern Indiana. The rhizomes and roots have been much used in medicine and since the plant is so conspicuous I fear "root collectors" have almost exterminated it. It is commonly known as black cohosh and to the eclectic physician as macrotys.
