Martha spotted this plant in a wooded area, near the railroad tracks, near the Fletcher Industrial Park and it was previously identified as a Wood Anemone. It appears to be a Northern Dewberry [Rubus flagellaris], a member of the Rose (Rosaceae) family. The latter photo shows the flower attached to a vine, which makes it more likely to be a Dewberry, see Newcomb’s Wildflower Guide, pages 330-331.
