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

Infrequent to rare in the area of the southern part of the state shown by the map. On black and white oak and beech and sugar maple wooded slopes. Probably entirely absent from most of the Tipton Till Plain and the lake area. I have specimens from dry, white oak woods in De Kalb and Lagrange Counties. Nieuwland collected it in St. Joseph County. It has been reported from 3 other counties, Dearborn, Floyd, and Putnam. The great variation in the length of the pubescence led to the naming of the extreme pubescent form but the species is now regarded as variable enough to include this form.
