From Flora of Indiana (1940) by Charles C. Deam
Known from Indiana only by a specimen collected in 1837 near New Albany by Dr. A. Clapp, which is now in the herbarium of Wabash College. I found it in southern Ohio the last of March in a habitat that convinces me that it can still be found in Indiana if search is made in early spring in the knobs on the ridges of Virginia pine and chestnut oak.
