From Flora of Indiana (1940) by Charles C. Deam
Found throughout the lake area, sometimes covering large peat areas that have just passed out of the tamarack and marsh stages into the soft maple and white elm stages. I have this [pubescent] form of the red raspberry from only four [northern tier] counties where it was found in tamarack bogs and moist, mucky soil.
