The Angiosperm Phylogeny Website (or APweb) is a well-known web site dedicated to research on angiosperm phylogeny and taxonomy.
The site is hosted by the Missouri Botanical Garden website and maintained by researchers, Peter F. Stevens and Hilary M. Davis. Peter F. Stevens is a member of the Angiosperm Phylogeny Group (APG). The taxonomy presented is broadly based on the work of the APG, with modifications to incorporate new results.
