Peacotum
A peacotum is a peach/ apricot/ plum hybrid, said to taste similar to fruit punch, trademarked by Zaiger's Genetics, a company that develops novel fruit through deliberate hybridization. An application to trademark the name nectacotum in the United States for varieties derived from nectarine-type peaches was made in 2003 but later abandoned.
