“Oompa Loompa” is a hybridized cultivar of Tecoma stans to which the botanical name Tecoma x smithii is sometimes assigned. William Watson of London first described this hybrid in 1893.

Some people with dwarfism have criticized the casting of British actor Hugh Grant in the role of an Oompa-Loompa in the upcoming film “Wonka,” saying that work is being “taken” from them.
