In the APG II system for the classification of the angiosperms the name rosids refers to a clade, meaning a monophyletic group of plants. The flowering plants or angiosperms ( Angiospermae or Magnoliophyta) are the most widespread group A clade is a taxonomic group comprising a single Common ancestor and all the descendants of that ancestor A clade is a taxonomic group comprising a single Common ancestor and all the descendants of that ancestor This clade is one of the two main groups in the eudicots, the other being the asterids. Eudicots and Eudicotyledons are terms introduced by Doyle & Hotton (1991 to refer to a group of Flowering plants that had been called "tricolpates" or "non-Magnoliid In the APG II system (2003 for the classification of Flowering plants, the name asterids refers to a Clade (a Monophyletic group

The clade includes, roughly speaking, those species that in the Cronquist system were referred to the Hamamelididae and Rosidae and quite a few from the Dilleniidae. A system of plant taxonomy, the Cronquist system is a scheme for the classification of flowering plants (or Angiosperms) Hamamelididae is a Botanical name at the rank of subclass. A well-known system that used this name is the Cronquist system, although in the disallowed Under the International Code of Botanical Nomenclature (ICBN Rosidae is a Botanical name at the rank of subclass. Dillenidae is a Botanical name at the rank of subclass. Circumscription of the subclass will vary with the taxonomic system being used the only The name "rosids" (plural, not necessarily capitalized) is presumably inspired by the botanical name, but in itself is intended to be the name of a clade rather than a formal ranked name, in the sense of the ICBN. A botanical name is a formal scientific name conforming to the International Code of Botanical Nomenclature (ICBN and if the plant is a Cultigen, the A clade is a taxonomic group comprising a single Common ancestor and all the descendants of that ancestor The International Code of Botanical Nomenclature ( ICBN) is the set of rules and recommendations dealing with the formal Botanical names that are given to
