As the APG have chosen to eschew ranks above order, this paper was meant to fit the system into the existing Linnaean hierarchy for those that prefer such a classification. The result was that all land plants were placed in the class Equisetopsida, which was then divided into 16 subclasses and a multitude of superorders. The second, by Haston ''et al.'', was a linear sequence of families following the APG III system (LAPG III). This provided a numbered list to the 413 families of APG III.

Phylogeny

The APG III system was based on a phylogenetic tree for the angiosperms which included all of the 59 orders and 4 of the unplaced families. The Systematics, systematic Plant taxonomy, positions of the other 6 unplaced families was so uncertain that they could not be placed in any of the polytomy, polytomies in the tree. They are shown in the classification table entitled #Detailed version (with all families), "Detailed version" above, 4 in Euasterids I and 2 in Taxa of uncertain position. The phylogenetic tree shown below was published with the APG III system, but without some of the labels that are added here.


Subfamilies replacing discontinued families

A number of subfamilies have been proposed to replace some of the families which were optional (i.e. bracketed) in APG II, but have been discontinued in APG III. These are shown in the table below.
