From Flora of Indiana (1940) by Charles C. Deam
Leaves usually 3, sometimes 4. Mostly in moist, rich beech and sugar maple woods and rarely in wet places in woods. It is rather local in a few of the northern counties and reappears in slightly acid soil in Decatur and Jennings Counties. The plant is rather inconspicuous and may be more common than the reports indicate.
