Dilleniales

The Dilleniales are an order of flowering plants, potentially containing one family, Dilleniaceae. The APG [III system] of 2009, like the earlier APG [II system] of 2003, left the Dilleniaceae unplaced as to order, while noting that the name Dilleniales was available. Stevens at the Angiosperm Phylogeny Website has subsequently placed Dilleniaceae in the order Dilleniales.
The Cronquist system, of 1981, recognized such an order and placed it in subclass Dilleniidae. It used the following circumscription:

The Takhtajan system of 1969 had the families Dilleniaceae and Crossosomataceae in the order.
The APG III system assigned the second of these families, the Paeoniaceae, to the order Saxifragales.
