Question
Great Meadows National Wildlife Refuge, Massachusetts. I was thinking Rubus (compound leaves, spines) but I did not find a convincing match in the key.
Answer
Dear jfc, good afternoon. You have photographed a young plant of Rosa rugosa (rambler rose). This non-native species is identified at this stage by the fringed stipules (at the base of the leaf), as opposed to toothed stipules in other roses within New England. Best wishes.
