Angiosperm Phylogeny Group
From Wikipedia, the free encyclopedia
The Angiosperm Phylogeny Group, or APG, refers to an informal international group of systematic botanists who came together to try to establish a consensus on the taxonomy of flowering plants (angiosperms) that would reflect new knowledge about plant relationships discovered through phylogenetic studies.
As of 2010, three incremental versions of a classification system have resulted from this collaboration published in 1998, 2003 and 2009. An important motivation for the group was, what they considered, deficiencies in prior angiosperm classifications since they were not based on monophyletic groups (i.e. groups that include all the descendants of a common ancestor).
APG publications are increasingly influential, with a number of major herbaria changing the arrangement of their collections to match the latest APG system.
