The first is in the relationship of the outgroups; in our analysis Vitis and Dipentodon are not sister groups, instead Vitis is sister to the Asteridae.
The combination of characters present in this taxon: small pentamerous flowers with cupulate hypanthium ending in a thick presumably nectariferous rim, triangular sepals with a prominent midvein or keel, thin clawed cucullate petals alternating with the sepals, and stamens opposite to the petals is not found in the Solanaceae or even in the Asteridae, but in the Rhamnaceae, a family that is today classified with the Order Rosales in the Rosid clade (APG, 1998, 2003).

The Asteridae is a group of flowering plants characterized by their fused corollas and iridoid compounds (Bremer et al.
The Asteridae as defined today is a remarkable group in many respects; for example, two of its families, Asteraceae (=Compositae, sunflower family) and Rubiaceae (coffee family) are among the most biodiverse plant families in terms of number of species.
Phylogenetic works focusing on all or parts of the Asteridae have substantially increased over the last few years (i.
Although the importance of the Asteridae has attracted attention in many areas of research and nearly 1/3 of all angiosperm species are asterids, their fossil record is not as extensive or even reflective of their extant diversity, especially in the large euasterid clade (sensu Soltis et al.

The Asteridae as presently delimited are a large taxon with many highly evolved members (Chase et al.

This tendency is either infrequent or absent in the basal members of the Asteridae.
