Clade of flowering plants
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 name is based upon the name "Rosidae ", which had usually been understood to be a subclass.
Relationships
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]
