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

Infrequent on the crests and slopes of chestnut oak and post oak ridges in the southern counties. All of my specimens except the one from Gibson County are from the unglaciated region. My Posey County specimen is from the east bank of "Pitcher Lake" about 5 miles northwest of Mt. Vernon. This bank is frequently submerged and this habitat seemingly is very different from that of the hills of the counties to the east.
