Dewberry

The dewberries are a group of species in the genus Rubus, section Rubus, closely related to the blackberries. They are small trailing (rather than upright or high-arching) brambles with berries reminiscent of the raspberry, but are usually purple to black instead of red. Unlike many other Rubus species, dewberries have separate male and female plants (they are dioecious) (Burbank, methods and applications 3, AD 1914).
