  Crossosomatales
Butterfly caterpillars are common on members of the group, occuring about twice as frequently as might be expected going by species number alone, but the tree habit is also common in the group, and trees perhaps support a correspondingly disproportionate number of larvae...
Furthermore, despite the apparently rather heterogeneous nature of Crossosomatales, Matthews and Endress (2005a, also 2006b for a summary) emphasise the number of distinctive features of the order, even if exactly where some of these are to be placed on the tree is unclear.
The age of Crossosomatales (stem group 89-83 million years before present, crown group 47-40 million years before present) properly refers to this clade (see Anderson et al.

 Crossosomatales - Wikipedia, the free encyclopedia
The Crossosomatales are an order, newly recognized by the AGP II, of flowering plants, included within the Rosids, which are part of the eudicots.
Under the Cronquist system these were placed in the Rosales, Violales, and Sapindales, respectively.
In addition there are four genera, each placed within its own family, that may belong here.

We focus upon orders which have new or novel circumscription following molecular studies and attempt to identify potential synapomorphies for these orders including potential synapomorpies for families or clades within the order.
To date we have studied Celastrales, Oxalidales, Crossosomatales and Cucurbitales and are beginning a project which focuses on the very large, unresolved order, Malpighiales.

 IngentaConnect Description and Phylogenetic Position of a New Angiosperm Family,...   (Site not responding. Last check: 2007-10-24)
Phylogenetic analyses of the chloroplast rbcL, atpB, and matK genes amplified from the materials, along with sequences from representatives of most major eudicot groups, strongly support Guamatela as a member of the rosid order Crossosomatales, as circumscribed in APG II.
None of the molecular data supports the inclusion of Guamatela in any described family in the order, and the unique combination of morphological characters does not fit the description of any of those families.
Based on these results, we here propose the new family Guamatelaceae to accommodate this genus.

A revised and updated classification for the families of the flowering plants is provided.
Newly adopted orders include Austrobaileyales, Canellales, Gunnerales, Crossosomatales and Celastrales.
Pertinent literature published since the first APG classification is included, such that many additional families are now placed in the phylogenetic scheme.

All in all, a postion of Vitales as sister to Rosids seem probable (see that page for more details and characters), but, other than that, everything seems somewhat up in the air.
For direct links to the other clades possibly involved, see Caryophyllales, asterids, Dilleniales, Crossosomatales, Saxifragales, Santalales, Vitales; in some cases there is further discussion immediately following or preceding the orders just mentioned.
For general information on core eudicot diversification, see Magallón et al.
