A revised and updated classification for the families of the flowering plants is provided. Newly adopted orders include Austrobaileyales, Canellales, Gunnerales, Crossosomatales and Celastrales. Pertinent literature published since the first APG classification is included, such that many additional families are now placed in the phylogenetic scheme. Among these are Hydnoraceae (Piperales), Nartheciaceae (Dioscoreales), Corsiaceae (Liliales), Triuridaceae (Pandanales), Hanguanaceae (Commelinales), Bromeliacae, Mayacaceae and Rapateaceae (all Poales), Barbeuiaceae and Gisekiaceae (both Caryophyllales), Geissolomataceae, Strasburgeriaceae and Vitaceae (unplaced to order, but included in the rosids), Zygophyllaceae (unplaced to order, but included in eurosids I), Bonnetiaceae, Ctenolophonaceae, Elatinaceae, Ixonanthaceae, Lophopyxidaceae, Podostemaceae (Malpighiales), Paracryphiaceae (unplaced in euasterid II), Sladeniaceae, Pentaphylacaceae (Ericales) and Cardiopteridaceae (Aquifoliales). Several major families are recircumscribed. Salicaceae are expanded to include a large part of Flacourtiaceae, including the type genus of that family; another portion of former Flacourtiaceae is assigned to an expanded circumscription of Achariaceae. Euphorbiaceae are restricted to the uniovulate subfamilies; Phyllanthoideae are recognized as Phyllanthaceae and Oldfieldioideae as Picrodendraceae. Scrophulariaceae are recircumscribed to include Buddlejaceae and Myoporaceae and exclude several former members; these are assigned to Calceolariaceae, Orobanchaceae and Plantaginaceae. We expand the use of bracketing families that could be included optionally in broader circumscriptions with other related families; these include Agapanthaceae and Amaryllidaceae in Alliaceae s.l. , Agavaceae, Hyacinthaceae and Ruscaceae (among many other Asparagales) in Asparagaceae s.l. , Dichapetalaceae in Chrysobalanaceae, Turneraceae in Passifloraceae, Erythroxylaceae in Rhizophoraceae, and Diervillaceae, Dipsacaceae, Linnaeaceae, Morinaceae and Valerianaceae in Caprifoliaceae s.l. © 2003 The Linnean Society of London, Botanical Journal of the Linnean Society , 2003, 141 , 399‐436.

开花植物目和科的被子植物系统发育群分类的更新：APG IV

提供了开花植物科的修订和更新分类。新采用的订单包括 Austrobaileyales、Canellales、Gunnerales、Crossosomatales 和 Celastrales。包括自第一次 APG 分类以来发表的相关文献，因此许多其他家族现在被置于系统发育图谱中。其中包括绣球花科（Piperales）、花椰菜科（Dioscoreales）、Corsiaceae（百合目）、Triuridaceae（Pandanales）、Hguanaceae（Commelinales）、凤梨科、Mayacaceae 和 Rapateaceae（所有 Poales）、Barbeuiaceae 和 Gisekiacesae、Gisekiacesaes Vitaceae（未分类，但包含在蔷薇科）、Zygophyllaceae（未分类，但包含在 Eurosids I 中）、 Bonnetiaceae、栉树科、Elatinaceae、Ixonanthaceae、Lophopyxidaceae、Podostemaceae (Malpighiales), Paracryphiaceae (unplaced in euasterid II), Sladeniaceae, Pentaphylacaceae (Ericales) 和 Cardiopteridaceae (Aquifoliales)。几个主要家庭被重新限制。杨柳科扩大到包括黄花科的很大一部分，包括该科的模式属；前 Flacourtiaceae 的另一部分被指定为 Achariaceae 的扩展范围。大戟科仅限于单排卵亚科；Phyllanthoideae 被认为是 Phyllanthaceae，Oldfieldioideae 被认为是 Picrodendraceae。玄参科被重新界定为包括佛兰科和木孔科，并排除了几个以前的成员；这些被分配到 Calceolariaceae、Orobanchaceae 和 Plantaginaceae。我们扩大了括号家庭的使用，这些家庭可以选择性地包含在与其他相关家庭的更广泛的范围内；这些包括天门冬科 sl 中的 Agapanthaceae 和石蒜科，天门冬科 sl 中的龙舌兰科，风信子科和 Ruscaceae（以及许多其他天门冬），Chrysobalanaceae 中的 Dichapetalaceae，西番莲科中的 Turneraceae，西番莲科中的 Turneraceae 和槭树科和槭树科，紫草科2003 伦敦林奈学会，林奈学会植物学杂志，2003，141，399-436。
