Running Swamp Blackberry

Perhaps you have seen the blackberry with fruit so small it seems only partially developed and, like myself, have hesitated to taste it, not being sure that it was a true blackberry and edible. It takes a good many of these little berries to make a mouthful, but they are harmless. They are called the running swamp blackberry. They ripen in August and grow in sandy places as well as in the swamps. There are three leaflets, seldom more, to the stem, which are blunt at the tip, smooth, shining, and coarsely toothed. The flowers are small and white, and the stems prickly.
