Taxonomy
The Cronquist system of 1981 assigned the order to the subclass Arecidae in the class Liliopsida (= monocotyledons).
The Thorne system (1992) and the Dahlgren system assigned the order to the superorder Areciflorae, also called Arecanae in the subclass Liliidae (= monocotyledons), with the single family Arecaceae.
The APG II system of 2003 recognised the order and placed it in the clade commelinids in the monocots and uses this circumscription:
This was unchanged from the APG system of 1998, although it used the spelling "commelinoids" instead of commelinids.
The APG IV system of 2016 places Dasypogonaceae in this order, after studies shown Dasypogonaceae as sister to Arecaceae.
