Angiosperm Phylogeny Group

The Angiosperm Phylogeny Group (APG) is a collaborative international organization that classifies flowering plants based on their evolutionary relationships, or how they are related through common ancestors. Using genetic and molecular data rather than just physical traits, APG has developed a modern, scientifically-accurate system to organize plant diversity. Their classifications help botanists, ecologists, and researchers better understand plant evolution, improve naming consistency, and reflect the true history of flowering plant species worldwide.
