From Flora of Indiana (1940) by Charles C. Deam

An infrequent plant throughout the state. It is generally found in deep humus, usually in beech and sugar maple and oak woods. The flowers are mostly nodding but the fruit is erect. I once found a large colony on a bare, sandy flat in a deep, wooded ravine. Besides the counties indicated on the map it has been reported from the following counties: Fayette, Hamilton, and Steuben.
