'''Ranunculales''' is an [[order (biologie)|order]] o [[flouerin plant]]s. O necessity it contains the [[Faimily (biologie)|faimily]] [[Ranunculaceae]], the [[buttercup]] faimily, because the [[botanical name| name]] o the order is [[Basionym|based]] on the [[Genus #Generic name| name]] o a [[genus]] in that faimily. Ranunculales belongs tae a [[paraphyletic]] [[Taxon|group]] kent as the basal eudicots. It is the maist [[Basal (phylogenetics)| basal]] [[clade]] in this group; in ether wirds, it is [[sister taxon| sister]] tae the remainin eudicots.

==Taxonomy==
The [[Angiosperm Phylogeny Group]] recognized seven faimilies in Ranunculales in their [[APG III system]], [[Academic publishin| published]] in 2009. In the preceding [[APG II system]], they offered the option o three [[Segregate (taxonomy)| segregate]] faimilies as shown below. 

* order Ranunculales
*: faimily [[Berberidaceae]]
*: faimily [[Circaeasteraceae]]
*:: [+ faimily [[Kingdoniaceae]] ]
*: faimily [[Eupteleaceae]]
*: faimily [[Lardizabalaceae]]
*: faimily [[Menispermaceae]]
*: faimily [[Papaveraceae]]
*:: [+ faimily [[Fumariaceae]] ]
*:: [+ faimily [[Pteridophyllaceae]] ]
*: faimily [[Ranunculaceae]]
Note: "+ ..." = optionally separate faimily (that mey be split aff frae the precedin faimily).

Unner this definition, well-kent memmers o Ranunculales include [[buttercup]]s, [[clematis]], [[Aquilegia|columbines]], [[delphinium]]s, an [[Papaveraceae|poppies]].

The [[Cronquist system]] (1981) also recognised the order, but placed it in the [[Subclass (biologie)| subclass]] [[Magnoliidae sensu Cronquist|Magnoliidae]], in [[Class (biologie)| class]] [[Magnoliopsida]] [= dicotyledons]. It uised this circumscription:
* order Ranunculales
*: faimily [[Ranunculaceae]]
*: faimily [[Circaeasteraceae]]
*: faimily [[Berberidaceae]]
*: faimily [[Sargentodoxaceae]]
*: faimily [[Lardizabalaceae]]
*: faimily [[Menispermaceae]]
*: faimily [[Coriariaceae]]
*: faimily [[Sabiaceae]]

In the Cronquist system, the Papaveraceae an Fumariaceae (includin the plants in the optional faimily Pteridophyllaceae) were treatit as a separate order '''Papaverales''', placed in this same subclass Magnoliidae. The Cronquist [[Circumscription (taxonomy)| circumscription]] o Ranunculales is nou kent tae be [[polyphyletic]]. Sabiaceae is in a clade o basal eudicots separate frae Ranunculales. Coriariaceae is now placed in the order [[Cucurbitales]].

A [[phylogeny]] o Ranunculales wis published in 2009, based on [[molecular phylogenetic]] analysis o [[DNA sequence]]s. The authors o this [[Scienteefic literature| paper]] revised the subfaimilies an [[Tribe (biologie)| tribes]] o the order.<ref name="weiwang2009">{{cite journal | doi = 10.1016/j.ppees.2009.01.001 | author = Wei Wang | coauthors = An-Ming Lu, Yi Ren, Mary E.
