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]

  • subclass Rosidae
order Rosales
order Fabales
order Proteales
order Myrtales
order
Rhizophorales
order Cornales
order Santalales
order Rafflesiales
order Celastrales
order Euphorbiales
order Rhamnales
order Linales
order
Polygalales
order Sapindales
order Geraniales
order Apiales

The Phylocode definition includes

sensu stricto
requires it to be included among the rosids. Vitales is sister to the clade of all that must be included in the rosids and its inclusion is optional. In APG III, it was included.

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

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.
