The Angiosperm Phylogeny Website (or APweb) is a website that presents up-to-date research on the phylogeny and taxonomy of flowering plants (angiosperms) in what is intended to be a user-friendly way. [1] The site is hosted by the Missouri Botanical Garden website and maintained by researchers, Peter F. Stevens and Hilary M. Davis. [1]
Evolution of the angiosperms according to the Angiosperm Phylogeny Group (2013). The Angiosperm Phylogeny Group (APG) is an informal international group of systematic botanists who collaborate to establish a consensus on the taxonomy of flowering plants (angiosperms) that reflects new knowledge about plant relationships discovered through phylogenetic studies.
The APG IV system of flowering plant classification is the fourth version of a modern, mostly molecular-based, system of plant taxonomy for flowering plants (angiosperms) being developed by the Angiosperm Phylogeny Group (APG).
The superasterids are members of a large clade (monophyletic group) of flowering plants, containing more than 122,000 species. [citation needed] The clade is divided into 20 orders as defined in APG IV system. These orders, in turn, together comprise about 146 families. [1]
The APG system (Angiosperm Phylogeny Group system) of plant classification is the first version of a modern, mostly molecular-based, system of plant taxonomy. Published in 1998 by the Angiosperm Phylogeny Group , it was replaced by the improved APG II in 2003, APG III system in 2009 and APG IV system in 2016.
Nymphaea alba, from the Nymphaeales. The basal angiosperms are the flowering plants which diverged from the lineage leading to most flowering plants. In particular, the most basal angiosperms were called the ANITA grade, which is made up of Amborella (a single species of shrub from New Caledonia), Nymphaeales (water lilies, together with some other aquatic plants) and Austrobaileyales (woody ...
The superrosids are members of a large clade (monophyletic group) of flowering plants, containing more than 88,000 species, [2] and thus more than a quarter of all angiosperms. [3] The clade is divided into 18 orders as defined in APG IV system. These orders, in turn, together comprise about 155 families. [1]
The Francoaceae are recognized as a family under various classification schemes. Under the 2009 APG III system the Francoaceae were included within the Melianthaceae. [1] In the 2016 APG IV system the Francoaceae are again recognized as a family, with Melianthaceae included in the circumscription of Francoaceae. [2]
