Mock Strawberry (Potentilla indica, 蛇莓).
Stoloniferous, it fortifies its positions close to the ground and is virulently resistant to human aggression: whether by foot or by mover. In exchange for our disturbances it offers bland (and slightly crunchy) red berries and trifoliate leaves, which provide a good poultice for insect bites and (I am told) burns as well. Along the Xiang river have found single berries here and there since midsummer, but they are now more numerous, often appearing in groups of five or six drupes.
