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.
