• order Arales
• : family Acoraceae
• : family Araceae
• : family Lemnaceae

In the classification system of Dahlgren the Arales were in the superorder Ariflorae (also called Aranae), but did not include Acoraceae as a separate family.{{Cite book |last=Singh |first=Gurcharan |url=https://books.google.com/books?id=MiGeDwAAQBAJ |title=Plant Systematics: An Integrated Approach, Fourth Edition |date=2019-06-07 |publisher=CRC Press |isbn=978-1-000-57677-1 |pages=255–259; 328–329 |language=en}} Instead, Acorus, its only genus, was included in the Araceae. Arales was the only order included in the Ariflorae.

The APG II system elevates the first of these three families to become an order Acorales of its own (consisting of the single genus, Acorus) and unites the last two of these families into the one family Araceae assigning this to the order Alismatales.
