Angiosperm Phylogeny Group IV
Quick Summary
The Angiosperm Phylogeny Group IV (APG IV) system is a botanical classification that organizes flowering plants (angiosperms). It primarily uses molecular data, such as DNA sequences, to determine evolutionary relationships, moving away from older systems based solely on morphology.1
The APG IV system recognizes informal higher-level groupings like eudicots, Rosids, and Asterids, and it acknowledges monocots as a distinct lineage. It organizes plants into orders and families, with family names typically ending in "-aceae" and order names in "-ales". This system is dynamic and subject to updates as new data emerge.21

angiospermIt is known as the Angiosperm Phylogeny Group IV (APG IV) botanical classification system. The angiosperms came to be considered a group at the division level (comparable to the phylum level in animal classification systems) called Anthophyta, though the APG system recognizes only informal groups above the level of order.
