Doryanthes excelsa, commonly known as gymea lily, is a flowering plant in the family, Doryanthaceae and is endemic to coastal areas of New South Wales near Sydney. It has sword-like leaves more than 1 metre (3 ft) long and when it flowers, sends up a flower spike up to 6 metres (20 ft) high. The apex of the spike bears a large cluster of bright red flowers, each 10 centimetres (4 in) across. Its common name is derived from the name given to the plant by the indigenous Eora people and the Sydney suburbs of Gymea and Gymea Bay are named after the lily.
