Found by W. A. MacKinnon in Alger Co., in 2019. This is a unique and easy to recognize species in an otherwise difficult genus, with its combination of yellow flowers and large, egg-shaped to nearly round leaves in a rosette lying more or less flat on the ground. The Michigan occurrence of this eastern, primarily Appalachian plant is a strikingly disjunct from the nearest occurrences in the eastern portions of southern Ontario and Ohio.
