 Trochodendrales
EuAP3/PI are involved in stamen identity very much as paleoAP3/PI, but the former may be involved in petal development in core eudicots.
For the loss of the rps2 mitochondrial gene, see Adams et al.
(2002b), for the duplication of the RPB2 gene, which may have occured in the immediate ancestor of Trochodendrales (well, of Trochodendron at least), see Oxelman et al.

 Trochodendron aralioides - UBC Botanical Garden Forums
Cronquist (1988) and Takhtajan (1996) both accept these as monotypic families (Trochodendraceae, Tetracentraceae), the sole families in the order Trochodendrales.
APG (Angiosperm Phylogeny Group, 1998, 2003) also recognize the order Trochodendrales, but allow the option of recognizing both families, or both under a single family (Trochodendraceae, as that has priority).
This is a good example of the arbitrariness of taxonomic ranks such as 'family' and 'order' -- either scheme works here to provide a perfectly natural (phylogenetic) classification.
