Gorteria is a genus of flowering plants in the daisy family. It was named in honour of the Dutch physicists and botanists Johannes de Gorter and his son David de Gorter. Researchers from Stellenbosch University and the University of KwaZulu-Natal in Pietermaritzburg showed that the ray florets of G. diffusa strongly resemble the bodies of female flies and cause male bombyliid flies to try to copulate with flowers, whilst they pollinate the flower.
