These pages are a series of characterizations of all orders and families of extant angiosperms (flowering plants) and gymnosperms, i.e. all seed plants, as well as many of clades grouping families and orders and some smaller clades, especially within larger families; non-seed plants are covered more briefly.

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.

2019年11月10日 · In 1998, a group of botanical researchers who called themselves the Angiosperm Phylogeny Group (APG) proposed their first classification for angiosperms based on the results of molecular phylogenetic analyses (i.e., analyses of molecular sequence data used to build trees of relationships among living angiosperms; see here). They used a ...

2017年8月4日 · Angiosperm phylogeny classification of flowering plants (APG IV) with the families organized alphabetically within orders. The Angiosperm Phylogeny Group 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 ...

Kew scientist Mike Fay discusses the issues with classifying flowering plant species, and the efforts made by the Angiosperm Phylogeny Group (APG) to reclassify species using technological advances in DNA sequencing.

2019年5月6日 · Angiosperms are by far the most species-rich clade of land plants, but their origin and early evolutionary history remain poorly understood. We reconstructed angiosperm phylogeny based on 80 genes...

2023年9月26日 · APG系统，或称为APG分类法，最早发布于1998年，由被子植物系统发育研究组（Angiosperm Phylogeny Group）以分支分类学和分子系统学为基础提出的被子植物分类系统，自1998年首次提出后，近年来又相继推出了三个修订版本（APG II 2003, APG III …

2016年3月1日 · This article presents an overview of Angiosperm Phylogeny Group classification, its genesis and culmination to APG III. An analysis of the 413 families recognized in APG III revealed that 259...

2009年10月1日 · An update of The Angiosperm Phylogeny Group classification for the orders and families of flowering plants: APG III. Botanical Journal of the Linnean Society October 2009

2012年1月1日 · Recent advances in angiosperm phylogenetics in particular have played a significant role in selecting taxa for genetic analysis and genome sequencing. Here we summarize current methods in phylogeny reconstruction and look toward future, large-scale approaches.
