In the APG II system (2003) for the classification of flowering plants, the name asterids refers to a clade (a monophyletic group). A modern system of plant taxonomy, the APG II system of plant classification was published in 2003 by the Angiosperm Phylogeny Group, APG, in Angiosperm Phylogeny Group (2003). ... Classes Magnoliopsida - Dicots Liliopsida - Monocots The flowering plants (also angiosperms or Magnoliophyta) are one of the major groups of modern plants, comprising those that produce seeds in specialized reproductive organs called flowers, where the ovulary or carpel is enclosed. ... A clade is group of organisms which share a common ancestor and which includes all decendents of that ancestor. ... In phylogenetics, a group is monophyletic (Greek: of one stem) if all organisms in that group are known to have developed from a common ancestral form, and all descendants of that form are included in the group. ...
Most of the taxa belonging to this clade had been referred to the Asteridae in the Cronquist system (1981) and to the Sympetalae in earlier systems. The name asterids (plural, not necessarily capitalized) is presumably inspired by the earlier 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. This clade is one of the two main groups of eudicots, the other being the rosids. It comprises: Asteridae is a botanical subclass of flowering plants in class Dicotyledon or Magnoliopsida. ... The Cronquist system is a scheme for the classification of flowering plants (or angiosperms). ... A botanical name is a formal name conforming to the ICBN. As with its zoological and bacterial equivalents it may also be called a scientific name. Botanical names may be in one part (genus and above), two parts (species) or three parts (below the rank of species). ... The International Code of Botanical Nomenclature is the set of rules according to which plants are given their formal botanical names (scientific names). ... In the APG-system, the names eudicots or tricolpates are applied to a monophyletic group that includes most of the (former) dicotyledons. ...

All euasterids are strongly supported as monophyletic, and with the six DNA regions analysed by Bremer et al.
Euasterid I had low jackknife/bootstrap support, 53%/66% (Olmstead et al., 2000), 56% (Soltis et al., 2000a) or 40% (Albach et al., 2001b), and euasterid II has 68% (Olmstead et al., 2000), 88% (Soltis et al., 2000a) or below 33% (Albach et al., 2001b).
Plocospermataceae, earlier unplaced in euasterid I, are the sister group to the rest of Lamiales (Oxelman, Backlund & Bremer, 1999; Savolainen et al., 2000a; Bremer et al., 2002), and Carlemanniaceae have been shown to be close to Oleaceae (Savolainen et al., 2000a).
