Taxonomy
In the Apg3 classification the Haloragaceae are part of the Saxifragales. In the past it had been placed in its own Order.
Plant theory
I n the first version of the Plant theory Haloragaceae was placed in its own Order and Subclass. The presumption was Haloragaceae is the Hydrogen series quality of the Malvidae. This was done because some are aquatics.
In Plant theory 2 the aquatic Myriophyllum is split of from Haloragaceae and placed in its own family Myriophyllaceae. The reason for doing so is that Myriophyllum is a real aquatic. That fits with the Hydrogen series in a similar way as Ceratophyllum.
The rest of the family is very different, being normal herbs and shrubs. Haloragaceae is tentaviely placed in Subphase 1of the Saxifragales. Included are the small families Aphanopetalaceae, Penthoraceae and Tetracarpaeaceae
