A name used in the APG (1998) and APG II (2003) systems for one of the principal clades accepted in the system. In practice the cause of some confusion as non-botanists tend to confuse it with a botanical name, with a formal rank.
Origin: Presumably inspired on subclass Rosidae.
The rosids are members of a large clade of flowering plants, containing about 70,000 species, more than a quarter of all angiosperms. The clade is divided into 16 to 20 orders, depending upon circumscription and classification. These orders, in turn, together comprise about 140 families. The rosids and the asterids are by far the largest clades in the eudicots. Fossil rosids are known from the Cretaceous period. Molecular clock estimates indicate that the rosids originated in the Aptian or Albian stages of the Cretaceous, between 125 and 99.6 million years ago.
