The Black Spot is a fictional literary device invented by Robert Louis Stevenson for his novel Treasure Island. In the book, a pirate is presented with a "black spot" to officially pronounce a verdict of guilt or judgment. It consists of a circular piece of black paper or card placed in the hand of the accused. It was a source of much fear because it meant the pirate will be executed. In Treasure Island, Billy Bones is so frightened by it he suffers a stroke and dies. There is no record of "black spots" in reality and how Stevenson came up with the idea is unknown.

Rose flspot, caused by the fungus Diplocarpon rosae, is the most common cause of defoliation of landscape roses in Eastern United States.
Blackspot can be distinguished from other leaf spot diseases of rose by the generally fringed margins and the darker and consistently fl color of the leaf spots.
Most roses get flspot to some degree, but roses that have been bred for resistance to this and another common disease of roses, powdery mildew, will require less maintenance than those that are known to be susceptible to these diseases.
