From Flora of Indiana (1940) by Charles C. Deam
In very sandy soil in woodland in the southwestern part of Posey County. I have specimens from three woods of this area. [A variation with linear to linear-oblong leaflets has been called forma angustifolia.] My only specimen is from very sandy soil (Princeton Fine Sand) on a wooded ridge about 2 miles north of Decker, Knox County. The northeastern limit of the range of several species of the southwest occurs on this ridge. The distribution of this form is not well known.
