A well-known example of Rosidae as governed by the ICN was in the Cronquist system. In the 1981, original, version of that system, the circumscription was as follows.[3]
There is considerable overlap between the two definitions. Some apparent differences are the result of more broadly drawn orders in the second. Apiales, Cornales, Proteales and Santalales, and parts of Rafflesiales (sensu Cronquist) are excluded from the second, and many groups from Cronquist's Hamamelidae and Dillenidae are included.
In both senses, the term "rosid" applies, as an adjective and noun, to members of the group. In the APG III system, which eschewed formal botanical names between the ranks of class and order, the term "rosids" is used to define an informal clade corresponding to Rosidae as defined in the Phylocode.
