A modern system of plant taxonomy, the APG system of plant classification was published in 1998 by the Angiosperm Phylogeny Group. The system is unusual in being based, not on total evidence, but on the cladistic analysis of the DNA sequences of three genes, two chloroplast genes and one gene coding for ribosomes. Although based on molecular evidence only, its constituent groups prove to be supported by other evidence as well, for example pollen morphology support the split between the eudicots and the rest of the former dicotyledons. This list of systems of plant taxonomy presents “taxonomic systems” used in plant classification. ... The Angiosperm Phylogeny Group is an international group of systematic botanists who have come together to try to establish a consensus view of the taxonomy of flowering plants in the light of the rapid rise of molecular systematics. ... This cladogram shows the relationship among various insect groups. ... Molecular biology is the study of biology at a molecular level. ... In the APG-system, the names eudicots or tricolpates are applied to a monophyletic group that includes most of the (former) dicotyledons. ... Orders see text Dicotyledons or dicots are flowering plants whose seed contains two embryonic leaves or cotyledons. ...

The system is rather controversial in its decisions at the family level, splitting a number of long-established families and submerging a number of other families. It also is unusual in not using botanical names above the level of order, that is, an order is the highest rank that will have a formal botanical name in this system. Higher groups are defined only as clades, with names such as monocots, eudicots, rosids, asterids. 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). ... In botanical nomenclature, a taxon is usually assigned to a rank in a hierarchy. ... 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). ... Orders Base Monocots: Acorus Alismatales Asparagales Dioscoreales Liliales Pandanales Family Petrosaviaceae Commelinids: Arecales Commelinales Poales Zingiberales Family Dasypogonaceae Monocotyledons or monocots are a group of flowering plants usually ranked as a class and once called the Monocotyledoneae. ... In the APG-system, the names eudicots or tricolpates are applied to a monophyletic group that includes most of the (former) dicotyledons. ... In the APG II system for the classification of the angiosperms the name rosids refers to a clade, meaning a monophyletic group of plants. ... In the APG II system (2003) for the classification of flowering plants, the name asterids refers to a clade (a monophyletic group). ...

It was succeeded in 2003 by the 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). ...

According to the presentation of the APG system at CSDL, Texas (which allows comparison in depth with other modern systems) the main groups in the system (all unranked clades) are: In botanical nomenclature, a taxon is usually assigned to a rank in a hierarchy. ... A clade is group of organisms which share a common ancestor and which includes all decendents of that ancestor. ...
