Blacberry

The blackberry is an edible fruit produced by many species in the Rubus genus in the Rosaceae family, hybrids among these species within the Rubus subgenus, and hybrids between the Rubus and Idaeobatus subgenera. What distinguishes the blackberry from itsraspberry relatives is whether or not the torus (receptacle or stem) 'picks-with' (ie stays with) the fruit. When picking a blackberry fruit, the torus does stay with the fruit. With a raspberry, the torus remains on the plant, leaving a hollow core in the raspberry fruit. The term 'bramble', a word meaning any impenetrable scrub, has traditionally been applied specifically to the blackberry or its products,^[1] though in the United States it applies to all members of the Rubus genus. In the western US, the term caneberry is used to refer to blackberries and raspberries as a group rather than the term bramble.
