 more tender and watery than the Garden or European Raspberry (R. Idccus),

 downy underneath ; the lateral ones somewhat stalked ; petals shorter than the 

 sepals ; fruit purple-black. Thickets and fields, especially where the ground has 

 been burned over. May. Fruit ripe early in July, pleasant. (Some curious

 bose, with leafy bracts; petals roundish. Var. 2. HUMIFTJSUS : trailing, small-
