Subdivisions
The eudicots can be divided into two groups: the basal eudicots and the core eudicots. Basal eudicots is an informal name for a paraphyletic group. The core eudicots are a monophyletic group.
A second study has suggested that the core eudicots can be divided into two clades - Pentapetalae - comprising all core eudicots except Gunnerales - and Gunnerales.
Pentapetalae can be then divided into three clades:
- (i) a "superrosid" clade consisting of Rosidae, Vitaceae and Saxifragales
- (ii) a "superasterid" clade consisting of Berberidopsidales, Santalales, Caryophyllales and Asteridae
- (iii) Dilleniaceae
Within the core eudicots, the largest groups are the "rosids" (core group with the prefix "eu−") and the "asterids" (core group with the prefix "eu−").
