context_page_description: The APG II system of plant classification is the second, now obsolete, version of a modern, mostly molecular-based, system of plant taxonomy that was published in April 2003 by the Angiosperm Phylogeny Group. It was a revision of the first APG system, published in 1998, and was superseded in 2009 by a further revision, the APG III system.
context_section_description: Main groups in the system (all unranked clades between the ranks of class and order):
  angiosperms :
  magnoliids
  monocots
  commelinids
  eudicots
  core eudicots
  rosids
  eurosids I
  eurosids II
  asterids
  euasterids I
  euasterids II
  Shown below is the classification in full detail, except for the fifteen genera and three families that were unplaced in APG II. The unplaced taxa were listed at the end of the appendix in a section entitled "Taxa of Uncertain Position". Under some of the clades are listed the families that were placed incertae sedis in that clade. Thirty-six families were so placed. This means that their relationship to other members of the clade is not known.
