Charles William Morrison of Estcourt, Natal, presented several rare butterflies to the South African Museum, Cape Town, in 1893, including "Precis Tugela, Aphnaeus Hutchinsonii, and the first extra-tropical example of the scarce Jolaus Pallene which has been received at the museum". In total there were ten species, collected at Karkloof, Weenen, Estcourt, and Tugela.
He was probably the same person as C.W. Morrison who was at the Broughton Fruit Estate, Northdene (near Durban) in 1903 and 1907. In 1916/7 Charles William Morrison of 568 Ridge Road, Durban, became a foundation member of the South African Biological Society. He was still listed as a member in 1920.
