ROSIDS

In the APG II system for the classification of the angiosperms the name 'rosids' refers to a clade, meaning a monophyletic group of plants. This clade is one of the two main groups in the 'eudicots', the other being the 'asterids'.
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. 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''.

★ clade 'rosids'
