The APG V system is the fifth version of a system of plant taxonomy for flowering plants (angiosperms) being developed by the Angiosperm Phylogeny Group (APG). It was published in 2026, ten years after its predecessor, the APG IV system, was published in 2016.
While APG I–IV were based primarily on plastid DNA analyses, APG V incorporates the results of large-scale nuclear phylogenomic analyses.
Changes at the Order Level Nuclear gene analyses resulted in changes to the circumscriptions of Icacinales, Aquifoliales, Oxalidales, and Bruniales in APG IV. New orders have been recognized: Oncothecales (containing only the family Oncothecaceae) and Cardiopteridales (containing the families Cardiopteridaceae and Stemonuraceae); meanwhile, the families Huaceae and Columelliaceae have been left unassigned to any order. The family Apodanthaceae, previously classified within the order Cucurbitales, has been shown to belong to the order Malpighiales; based on these results, the family has been reassigned to the Rafflesiaceae.
