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]
The Single Convention is the main international treaty related to Cannabis sativa L. and its products.In its Article 1, the Single Convention defines "cannabis" as the "flowering or fruiting tops of the cannabis plant (excluding the seeds and leaves when not accompanied by the tops) from which the resin has not been extracted, by whatever name they may be designated;" while "cannabis resin" is ...
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 ...
The order Rosales is strongly supported as monophyletic in phylogenetic analyses of DNA sequences, such as those carried out by members of the Angiosperm Phylogeny Group. [7] In their APG III system of plant classification, they defined Rosales as consisting of the nine families [3]: Cannabaceae (hemp family) Dirachmaceae
The APG III system of 2009 dropped the option of keeping the three families separate, using only the expanded family, still under the name Xanthorrhoeaceae. [14] Anticipating a decision to conserve the name Asphodelaceae over Xanthorrhoeaceae (which came to pass in 2017), the APG IV system uses Asphodelaceae as the name for the expanded family. [2]
