The Angiosperm Phylogeny Group (an international group of botanists working together to establish a new stable classification for flowering plants, using the results of many DNA studies) has published the fourth version of its classification, the APG IV:
Angiosperm Phylogeny Group (2016). “An update of the Angiosperm Phylogeny Group classification for the orders and families of flowering plants: APG IV” (PDF). Botanical Journal of the Linnean Society 181 (1): 1–20.doi:10.1111/boj.12385.
New editions of the “List of Names of woody plants” and “List of names of perennials” have been published by the European Nursery stock Association (ENA) and the Internationale Stauden Union (ISU). The lists contain over 45,000 names of woody plants and 24,000 names of perennials, and can be purchased in paper or electronic format:
Of interest to many horticulturists, the lists of changes to plant names are available freely from these two links:
- For woody plants:
- For perennials:
Changes include for example the transfer of Michelia spp. to Magnolia spp., and the transfer of some Persicaria species to Aconogon.
