Clades[1]

The superrosids are members of a large clade (monophyletic group) of flowering plants, containing more than 88,000 species,[2] more than a quarter of all angiosperms.[3]

The clade is divided into 18 orders as defined in APG IV system. These orders, in turn, together comprise about 155 families.[1]

The name is based upon the name "Rosidae", which had usually been understood to be a subclass.

Relationships[edit]

The rosids and Saxifragales form the superrosids clade.[4] This is one of three groups that compose the Pentapetalae (core eudicots minus Gunnerales),[5] the others being Dilleniales and the superasterids (Berberidopsidales, Caryophyllales, Santalales, and asterids).[4]
