The superrosids are members of a large clade (monophyletic group) of flowering plants, containing more than 88,000 species,[2] and thus 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 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]
