- A valuable resource, with considerable detail and discussion, as well as
incorporating the latest results, is the Angiosperm Phylogeny Website: A website detailing molecular phylogeny of the
flowering plants, constantly updated and including discussions on placements,
detailed phylogenies, characters of groups, common names, etc. Developed and maintained by Peter Stevens (Missouri Botanical Gardens and the University of Missouri) and Hilary Davis.
- A Poster of Angiosperm Phylogeny: A chart of orders using a standard tree-based representation,
incorporating morphological characters of clades (Theodor C.H. Cole (Heidelberg) and Hartmut H. Hilger (Berlin)).
- A chart of angiosperm orders, prepared by Helmut Dalitz, (using APG-III) is available, in several versions, from
Institut fur Botanik, Universitat Hohenheim, Stuttgart.
- A useful resources for information about parasitic plants and their classification is
The Parasitic Plant Connection website.
The work of the Angiosperm Phylogeny Group (APG) is central to
the new phylogeny of flowering plants. The latest form of this is summarised in:
- Angiosperm Phylogeny Group. An update of the Angiosperm Phylogeny Group
classification for the
orders and families of flowering plants: APG III. Botanical Journal of the Linnean Society, 2009. 161: 105-121.
Many other papers contribute to the development of angiosperm phylogeny and have been consulted in the design of the chart. A large bibliography can be found on the Angiosperm Phylogeny Website. More recent results refine and update parts of the
APG III classification and have been included on the chart.
The chart, index and website were developed by David Rydeheard. To contact me with comments, corrections or any other matters concerning this site, please email me
