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.
