Rosopsida Batsch 1788 is a
botanical name for a group of
flowering plants recognized at the
rank of class. The name is derived from that of the included family
Rosaceae. The name has not been used in most of the more influential recent classification systems, such as the
Cronquist system, the
Thorne system, the
Takhtajan system or the
APG II system. As circumscribed in the
Reveal system it is a subset of the
dicots, a
paraphyletic group recognized at various ranks in other systems, and includes:
Reveal's circumscription of the group corresponds largely to Cronquist's class Magnoliopsida (but minus subclass Magnoliidae) and to the eudicots of the APG II system minus Ranunculales and some other early-branching groups.
