Asphodeloideae is a subfamily of the monocot family Xanthorrhoeaceae in the order Asparagales. It has previously been treated as a separate family, Asphodelaceae. The family Asphodelaceae has now been proposed to be a nomen conservandum, and the proposal has been recommended for ratification at the next IAPT Congress in 2017. In that case, Asphodelaceae will have priority over Xanthorrhoeaceae. This is reflected in the APG IV family lists.
