From Flora of Indiana (1940) by Charles C. Deam
Very common throughout Indiana except in the northwestern counties from which we have no records. It is a plant of rich woods, occurring in dry neutral soil, especially on the slopes of deep ravines. It is most frequently associated with either Carex hitchcockiana or C. oligocarpa or both.
