From Flora of Indiana (1940) by Charles C. Deam
Rather frequent in the unglaciated area of southern Indiana and rare in the northern part of the state. It is generally found on black and white oak ridges and rarely with beech. It prefers a rich soil of weathered sandstone and it may be entirely absent in neutral or alkaline soils. A glabrous form of this species has been described but it may not occur in Indiana as all of my 41 specimens are copiously pubescent.
