Gourt Home::Gourt :: APG II system
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). An update of the Angiosperm Phylogeny Group classification for the orders and families of flowering plants: APG II. Botanical Journal of the Linnean Society 141: 399-436. (Available online: Abstract | Full text (HTML) | Full text (PDF))
The APG II system is the successor of the APG system. Each of these systems represents the broad consensus of a number of systematic botanists, united in the APG, working at several institutions worldwide. Continued development beyond APG II can be followed at the APG-companion site .
The APG II system has proven to be influential and has been adopted in whole or in part (sometimes with modifications) in a number of recent references.
Main groups in the system (all unranked clades):
- angiosperms :
