The APG IV system of flowering plant classification is the fourth version of a modern, mostly molecular-based, system of plant taxonomy for flowering plants (angiosperms) being developed by the Angiosperm Phylogeny Group (APG).
The APG system (Angiosperm Phylogeny Group system) of plant classification is the first version of a modern, mostly molecular-based, system of plant taxonomy. Published in 1998 by the Angiosperm Phylogeny Group , it was replaced by the improved APG II in 2003, APG III system in 2009 and APG IV system in 2016.
Peter F. Stevens is a member of the Angiosperm Phylogeny Group (APG). The taxonomy presented is broadly based on the work of the APG, with modifications to ...

In the United States in 2006, a photographic survey of the plants of the US and Canada is organized according to the APG II system. [8] In the UK, the 2010 edition of the standard flora of the British Isles (by Stace) is based on the APG III system. The previous editions were based on the Cronquist system. [9]
This template produces phylogenetic trees based on the Angiosperm Phylogeny Group IV (APG IV). [1] The whole system can be output as a large cladogram or sections can be selected for partial transclusion.
Generally, drugs outlined within the ATC code N04 should be included in this category. Please see WP:PHARM:CAT for more information. Wikimedia Commons has media related to Antiparkinsonian agents .
In several major drug classification systems, these four types of classifications are organized into a hierarchy. [4] For example, fibrates are a chemical class of drugs (amphipathic carboxylic acids) that share the same mechanism of action ( PPAR agonist ), the same mode of action (reducing blood triglyceride levels), and are used to prevent ...
