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: A botanical name is a formal name conforming to the ICBN. As with its zoological and bacterial equivalents it may also be called a scientific name. Botanical names may be in one part (genus and above), two parts (species) or three parts (below the rank of species). ...

Subfamilies Rosoideae Spiraeoideae Maloideae Amygdaloideae or Prunoideae The Rosaceae or rose family is a large family of plants, with about 3,000-4,000 species in 100-120 genera. ... A system of plant taxonomy, the Cronquist system is a scheme for the classification of flowering plants (or angiosperms). ... A modern system of plant taxonomy, the Thorne system of plant classification was drawn up by the botanist Robert F. Thorne (1920- ). The system has been modified numerous times, with the most recent published in 2000. ... A system of plant taxonomy, the Takhtajan system of plant classification was published by Armen Takhtajan, in several versions from the 1950s onwards. ... The Angiosperm Phylogeny Group is an international group of systematic botanists who have come together to try to establish a consensus view of the taxonomy of flowering plants in the light of the rapid rise of molecular systematics. ... A modern system of plant taxonomy, the Reveal system of plant classification was drawn up by the botanist J.L.

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. Orders Caryophyllales Polygonales Plumbaginales Caryophyllidae is a subclass of plants in the older Cronquist classification scheme. ... Hamamelididae is a botanical name at the rank of subclass. ... Dilleniidae is a botanical name at the rank of subclass. ...

Asteridae is a botanical subclass of flowering plants in class Dicotyledon or Magnoliopsida. ... Magnoliopsida is the botanical name for a class: this name is formed by replacing the termination -aceae in the name Magnoliaceae by the termination -opsida (Art 16 of the ICBN). ... Orders Magnoliales Laurales Piperales Aristolochiales Illiciales Nymphaeales Ranunculales Papaverales Magnoliidae is a sub-class of the Dicotyledon flowering plants in the Cronquist system. ... In the APG-system, the names eudicots or tricolpates are applied to a monophyletic group that includes most of the (former) dicotyledons. ... Families See text The Ranunculales are an order of flowering plants, which belong among the basal eudicots. ...
The ranunculoids are isolated from the magnoloids where they have been placed traditionally, and it is from here (rather than the magnoloids) where the higher angiosperms probably arose.
The rosoids (Rosopsida) are the most advanced of the dicotyledonous angiosperms.
The Nelumbonaceae, traditionally associated with the Nymphaeanae, is markedly distinct from that subclass of the piperoids and is placed here in a basal position in the Rosopsida.
