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).
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 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.

Boraginaceae, the borage or forget-me-not family, includes about 2,000 species of shrubs, trees, and herbs in 146 [3] to 154 genera with a worldwide distribution. [4]The APG IV system from 2016 classifies the Boraginaceae as single family of the order Boraginales within the asterids. [5]
The APG III system (2009; unchanged from the APG II system of 2003 and the APG system of 1998) places the family in the order Ranunculales, in the clade eudicots. [1] The Papaveraceae differ from the rest of the Ranunculales in some important characteristics but they share others such as the presence of isoquinoline-derived alkaloids.
The former family Asclepiadaceae is included in Apocynaceae according to the Angiosperm Phylogeny Group III modern, largely molecular-based system of flowering plant taxonomy. [11] An updated classification, including 366 genera, 25 tribes, and 49 subtribes, was published in 2014. [12] 376 genera are currently accepted. [13]
