Alismatales
Showy and delicate flowers of the flowering rush (Butomus umbellatus).
In the APG IV classification system, the Alismatales are placed within the monocotyledons (monocots), a large and monophyletic lineage of flowering plants.
Specifically, the APG IV system categorizes the Alismatales as part of the non-commelinid group of monocots. Within this hierarchy, the order is positioned alongside other non-commelinid orders such as Acorales—which is identified as the basalmost branch of the monocots—Asparagales, Dioscoreales, Liliales, Pandanales, and Petrosaviales.1
