'''Ranunculaceae''' ('''buttercup''' or '''crowfoot family'''; [[Latin]] ''rānunculus'' "little frog", from ''rāna'' "frog") is a [[family (biology)|family]] of over 2,000 known species of [[flowering plant]]s in 43 genera,{{sfn|Christenhusz|Byng| 2016}}  distributed worldwide.

The largest genera are ''[[Ranunculus]]'' (600 species), ''[[Delphinium]]'' (365), ''[[Thalictrum]]'' (330), ''[[Clematis]]'' (325), and ''[[Aconitum]]'' (300).

==Description==
[[File:Adonis autumnalis flowerdiagram.png|thumb|125px|[[Floral diagram]]. ''[[Adonis annua]]]]
Ranunculaceae are mostly [[herbaceous]] annuals or perennials, but some woody climbers (such as ''[[Clematis]]'') or shrubs (e.g. ''[[Xanthorhiza]]'').

Most members of the family have bisexual flowers which can be showy or inconspicuous, and can be radially or bilaterally symmetrical. The sepals and petals are generally free (unfused) and typically number four or five. In many species, the sepals are colorful and appear petal-like. In these species, the petals can be inconspicuous or absent. The stems are unarmed. The leaves are variable. Most species have both basal and cauline (stem) leaves, which are usually compound or lobed but can be simple. They are typically alternate, or occasionally opposite or even whorled. Many species, especially the perennials form [[rhizome]]s that develop new roots each year.<ref name=fna/>

Flowers may be solitary, but are frequently found aggregated in [[Cyme (botany)|cymes]], [[panicle]]s, or [[Raceme|spikes]].

The [[fruit]] is most commonly an [[achene]] (e.g. ''[[Ranunculus]]'', ''[[Clematis]]'') or a [[Follicle (fruit)|follicle]] (e.g. ''[[Helleborus]]'', ''[[Nigella]]'').

Ranunculaceae contain [[protoanemonin]], which is toxic to humans and animals. Other poisonous or toxic compounds, [[alkaloid]]s and [[glycoside]]s, are also common.

==Taxonomy==

Takhtajan (1997) included the Ranunculaceae as the only family in the Ranunculales which he placed in a subclass, the Ranunculidae, instead of a superorder.   Previously, Thorn (1992) placed the Ranunculaceae in the Berberidales, an order within the Superorder Magnolianae. Earlier Cronquist in 1981 included the Ranunculaceae along with seven other families in the Rancunculales which was included in the Magnoliidae, which he regarded as a subclass.<ref>[http://botany.csdl.tamu.edu/FLORA/newgate/cronang.htm Flowering Plant Gateway]</ref> David, (2010)<ref>[http://apps.rhs.org.uk/rhsplantfinder/documents/Essay.pdf Plants in their proper places]</ref> placed the Ranuculaceae, together with the Eupteleaceae, Lardizabalaceae, Menispermaceae, Berberidaceae, and Papaveraceae in the Ranunculales, the only order in the superorder Ranunculanae.  This follows the work of the [[Angiosperm Phylogeny Group]].

The family Ranunculaceae ''[[sensu stricto]]'' (APG) is one of seven families included in the [[order (biology)|order]] [[Ranunculales]] within the  [[eudicots]] according to the [[Angiosperm Phylogeny Group]] classification.{{sfn|APG|2016}} The family is [[monophyletic]] with ''[[Glaucidium (plant)|Glaucidium]]'' as [[sister group|sister]] to the remaining genera.{{sfn|Wang et al|2009}} This [[phylogeny]] is illustrated in the APG Poster.<ref>[http://www2.biologie.fu-berlin.de/sysbot/poster/poster1.pdf  Angiosperm Phylogeny Poster]</ref>

=== Subdivision ===

Early subdivisions of the family, such as [[Adanson]] (1763), simply divided it based on one-seeded or many-seeded fruit. [[Karl Anton Eugen Prantl|Prantl]] (1887) envisaged three [[tribe (biology)|tribes]], Paeonieae, Hellebroreae and Anemoneae with ''[[Peony|Paeonia]]'', ''[[Glaucidium (plant)|Glaucidium]]'' and ''[[Hydrastis]]'' forming Paeoniaae. By the twentieth century Langlet (1932) used chromosome types to create two [[subfamilies]], Ranunculoideae and Thalictroideae. In 1966 [[Minoru N. Tamura|Tamura]] further developed Langlet's system by adding floral characteristics with six subfamilies;
* Helleboroideae  
* Ranunculoideae 
* Isopyroideae
* Thalictroideae
* Coptidoideae
* Hydrastidoideae

but by 1988 he had reduced Coptidoideae to a tribe within Isopyroideae, leaving five subfamilies, an arrangement he continued in his 1993 monograph, dividing the larger subfamilies into tribes, though by then ''Paeonia'' and ''Glaucidium'' were no longer considered to belong to Ranunculaceae.{{sfn|Tamura|1993}} ''Paeonia'' was separated from Ranuculaceae and placed in its own family of [[Paeoniaceae]] (order [[Saxifragales]]). other genera originally included in Ranunculaceae include ''[[Circaeaster]]''  which was placed in its own family [[Circaeasteraceae]].

Tamura's complete system was structured as follows;
;Subfamilies and tribes
* Subfamily Ranunculoideae <small>Hutch.</small>
** Adonideae <small>Kunth</small>
** Anemoneae <small>DC.</small>
** Ranunculeae <small>DC.</small>
* Subfamily Helleboroideae <small>Hutch.</small>
** Helleboreae <small>DC.</small>
** Cimicifugeae <small>Torrey & A.Gray</small>
** Delphineae <small>Schrödinger</small>
** Nigelleae <small>Schrödinger</small>
* Subfamily Isopyroideae <small>Tamura</small>
** Coptideae <small>Langlet ex Tamura & K.Kosuge</small>
** Dichocarpeae <small>Tamura & K.Kosuge</small>
** Isopyreae <small>Schrödinger</small>
* Subfamily Thalictroideae
* Subfamily Hydrastidoideae

The genus ''[[Glaucidium (plant)|Glaucidium]]'', having been moved to its own family (Glaucidiaceae), has since been restored to Ranuculaceae.

=== Molecular phylogenetics ===

When subjected to [[molecular phylogenetic]] analysis only Thalictroideae is monophyletic. The position of ''Glaucidium'' and some of its unique morphological characteristics prompted Stevens to suggest that it be given subfamilial rank as the monotypic Glaucidioideae. Similarly Hydrastis has been assigned to subfamily Hydrastidoideae.{{sfn|Stevens|2017}}{{sfn|Wang et al|2009}} Both genera are represented by a single species, ''[[Glaucidium (plant)|Glaucidium palmatum]]'' and ''[[Hydrastis|Hydrastis canadense]]'' respectively.

The relationships between the genera suggest the existence of three major [[clades]] corresponding to Coptidoideae, Thalictroideae (clade A) and Ranunculoideae (clade F). The latter is the largest with four subclades (B–E). Of these C corresponds to Delphineae, D to Cimicifugae and E to Ranunculoideae.{{sfn|Wang et al|2009}} Consequently, Wang and colleagues (2009) proposed a new classification with five subfamilies, and further subdividing Ranunculoideae into ten tribes. The relationship between the subfamilies is shown in the [[cladogram]];

In addition to the two monotypic subgenera, Coptoideae has 17 species and Thalictroideae has 450, including ''[[Thalictrum]]'' and ''[[Aquilegia]]''. The other genera (2025 species, 81% of the family) belong to Ranunculoideae. ''[[Kingdonia]]'' had been included by Tamura in Anemoneae, but is now added to Circaeasteraceae.

=== Fossil record ===

Fossils of fruits, pollen, seeds, and leaves are known from several dozen locations.  The fossil record begins in the early [[Cretaceous]] and continues throughout the [[Tertiary]]. In most cases, the fossils are assigned to extant genera, or show a close relationship to a particular extant genus.{{sfn|Pigg|DeVore|2005}}

== Uses ==

Some Ranunculaceae are used as [[herbal medicine]]s because of their alkaloids and glycosides, such as ''[[Hydrastis canadensis]]'' (goldenseal), whose root is used as a tonic. More than 30 species are used in [[homeopathy]], including ''[[Aconitum napellus]]'',  ''[[Cimicifuga racemosa]]'', ''[[Clematis recta]]'', ''[[Clematis virginiana]]'', ''Hydrastis canadensis'', ''[[Ranunculus bulbosus]]'', ''[[Helleborus niger]]'', ''[[Delphinium staphisagria]]'', ''[[Pulsatilla nigricans]]''. Many genera are well known as cultivated flowers, such as ''[[Aconitum]]'' (monkshood), ''[[Clematis]]'', ''[[Consolida]]'' (larkspur), ''[[Delphinium]]'', ''[[Helleborus]]'' (Christmas rose), ''[[Trollius]]'' (globeflower). The seeds of '' [[Nigella sativa]]'' are used as a spice in Indian and Middle Eastern cuisine.{{sfn|Turner|1984}}
