one of many families or subfamilies into which some classification systems subdivide the Liliaceae but not widely accepted; sometimes included in subfamily Amaryllidaceae.

The Alstroemeriaceae is a family of flowering plants, with 200 species in three or four genera, native to the Americas, from Central America to southern South America. The APG II system, of 2003 (unchanged from the APG system, of 1998), treats the family in the order Liliales, in the clade monocots.
