Doryanthes is the sole genus in the flowering plant family Doryanthaceae. The genus consists of two species, D. excelsa (gymea lily) and D. palmeri (giant spear lily), both endemic natives of the coast of Eastern Australia. Doryanthaceae is part of the order Asparagales (the asparagoid lilies).

Plants grow in a rosette form, only flowering after more than 10 years. They enjoy a warm environment, good soil, and much water during the warmest time of the year.
