Gatton Sunray was registered by Sir Jeremiah Colman in 1919.
According to the RHS, it is a cross of Den. pulchellum & Den. Illustre, with the latter being a primary (chrysotoxum x pulchellum).
HOWEVER, it is known that this is incorrect. There have been several attempts at remaking Gatton Sunray, but using the official parents results in plants with entirely different flowers.
Also, chrysotoxum has 12" tall canes, and pulchellum has 15-18" tall canes. Gatton Sunray can grow 36-48" tall!
