Description:

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 its raspberry relatives is whether the torus (receptacle) picks with the fruit, a blackberry, or remains on the plant when picked, leaving a hole in the fruit, a raspberry. 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. The (usually) black fruit is not a true berry; botanically it is termed an aggregate fruit, composed of small drupelets. It is a widespread and well-known group of over 375 species, many of which are closely related apomictic microspecies native throughout Europe, northwestern Africa, temperate western and central Asia and North and South America
