[[File:EB1911 Flower - diagram of Fritillaria flower.jpg|thumb|[[Floral diagram]] of ''Fritillaria'' flower]]
'''''Fritillaria''''' ('''fritillaries''') is a [[genus]] of spring flowering [[herbaceous]] [[bulbous]] [[perennial]] plants in the lily [[family (biology)|family]] ([[Liliaceae]]). The [[type species]], ''[[Fritillaria meleagris]]'', was first described in Europe in 1571, while other species from the Middle East and Asia were also [[introduced species|introduced]] to Europe at that time. The genus has about 130–140 [[species]] divided among eight [[subgenera]]. The flowers are usually solitary, nodding and bell-shaped with bulbs that have fleshy scales, resembling those of [[lilies]]. They are known for their very large [[genome size]] and genetically are very closely related to lilies. They are [[native plant|native]] to the [[temperate regions]] of the [[Northern hemisphere]], from the [[Mediterranean]] and [[North Africa]] through [[Eurasia]] and southwest Asia to western [[North America]]. Many are [[endangered]] due to enthusiastic picking. The name ''Fritillaria'' is thought to refer to the checkered pattern of ''F. meleagris'', resembling a box in which [[dice]] were carried. Fritillaries are commercially important in [[horticulture]] as [[ornamental garden plants]] and also in [[traditional Chinese medicine]], which is also endangering a number of species. ''Fritillaria'' flowers have been popular subjects for artists to depict and as emblems of regions and organisations.

==Description==
[[File:Fritillaria meleagris - kockás kotuliliom.jpg|thumb|''[[Fritillaria affinis|F. meleagris]]'' showing [[campanulate]] [[perianth]] with [[tesselated]] segments]]
[[File:Fritillaria uva-vulpisBulb.tif|thumb|Bulb of ''[[Fritillaria uva-vulpis]]'']]
''Fritillaria'' is a [[genus]] of [[herbaceous]] [[bulbous]] [[perennials]].{{sfn|Day et al|2014}} It is [[phenotypic trait|characterised]] by nodding (pendant) flowers, [[perianths]] [[campanulate]] (bell- or cup-shaped) with erect segments in upper part, a [[nectarial]] pit, groove or pouch at the base of the [[tepal]], [[anthers]] usually pseudobasifixed, rarely versatile, fruit sometimes winged, [[embryo]] minute.{{sfn|Tamura|1998}}

[[Flowers]] often solitary and nodding, but some form [[umbels]] or have [[racemes]] with many flowers. Perianth campanulate (bell or cup shaped) and its segments usually [[tesselated]] with squares of alternating light and dark colours. [[Nectaries]] are large and well developed, and in most species (with the exception of ''Rhinopetalum''), are linear to [[lanceolate]] or [[Glossary of leaf morphology#ovate|ovate]] and weakly impressed upon the tepals.

The bulbs typically consist of a few tightly packed fleshy scales with a translucent [[tunica (biology)|tunic]] that disappears with further growth of the bulb. However, some species have naked bulbs with many scales and loosely attached [[Bulbs#Bulbils|bulbils]], resembling those of the closely related ''[[Lilium]]''.{{sfn|Rønsted et al|2005}}

Certain species have flowers that emit disagreeable odors. The [[scent]] of ''[[Fritillaria imperialis]]'' has been called "rather nasty", while that of ''[[Fritillaria agrestis|F. agrestis]]'', known commonly as stink bells, is reminiscent of [[Feces|canine feces]]. On the other hand, ''[[Fritillaria striata|F. striata]]'' has a sweet fragrance.{{sfn|McGary|2012}}

=== Genome ===

''Fritillaria'' represents the most extreme case of [[genome]] size expansion in [[angiosperms]]. [[Polyploidy]] is rare, with nearly all species being [[diploid]] and only occasional reports of triploidy.{{sfn|Day et al|2014}} Reported [[genome size]] in  ''Fritillaria'' vary from [[C-value|1Cx]] ([[DNA]] content of unreplicated [[haploid]] chromosome complement) values of 30.15 to 85.38&nbsp;Gb (Giga [[base pair]]s), that is >&nbsp;190 times that of ''[[Arabidopsis thaliana]]'', which has been called the "model plant"{{sfn|Day et al|2014}} and >&nbsp;860 times that of ''[[Genlisea aurea]]'', which represents the smallest land plant genome [[sequenced]] to date.{{sfn|Kelly et al|2015}} Giant genome size is generally defined as >35&nbsp;pg (34&nbsp;Gb).{{sfn|Leitch|2017}} The largest genomes in diploid ''Fritillaria'' are found in subgenus ''Japonica'', exceeding 85&nbsp;Gb.{{sfn|Day et al|2014}} At least one species, tetraploid ''[[Fritillaria assyriaca|F. assyriaca]]'', has a very large genome. With approximately 127&nbsp;[[picogram|pg]] (130&nbsp;Gb), it was for a long time the largest known genome, exceeding the largest [[vertebrate]] animal genome known to date, that of the [[marbled lungfish]] (''Protopterus aethiopicus''), in size.{{sfn|Science Daily|2010}} [[Heterochromatin]] levels vary by [[biogeographic]] region, with very little in [[Old World]] and abundant levels in [[New World]] species. Most species have a basic [[chromosome number]] of x=12, but x=9, 11 and 13 have been reported.{{sfn|Rønsted et al|2005}}

=== History ===
==== Pre-Linnaean ====

[[John Gerard|Gerard]] (1597) states that  ''Fritillaria'' was unknown to the [[classical antiquity|ancients]],{{sfn|Gerard|1597}} but certainly it was appearing in the writings of sixteenth century European botanists, including [[Dodoens]] (1574, 1583),{{sfn|Dodoens|1574}}{{sfn|Dodonaei|1583}} [[Lobelius]] (1576, 1581),{{sfn|l'Obel|1576}}{{sfn|l'Obel|1581}} and [[Carolus Clusius|Clusius]] (1583){{sfn|Clusius|1583}} in addition to Gerard, and was mentioned by [[Shakespeare]] and other authors of the period (see [[#Culture|Culture]]).{{sfn|Scarry|2016}} Species of Fritillaria were known in Persia (Iran) in the sixteenth century, from where they were taken to Turkey. European travelers then brought back specimens together with many other exotic eastern plants to the developing [[botanical gardens]] of Europe.<ref name=Pavord11/> By the middle of the sixteenth century there was already a flourishing export trade of various bulbs from Turkey to Europe.{{sfn|Pavord|1999}} In Persia, the first mention in the literature was by Hakim Mo'men Tonekabon in his ''Tohfe  Al-Mo'menin'' in 1080 [[Hijri year|AH]] ([[ca.]] 1669 AD), who described the medicinal properties of ''F. imperialis'' (''laleh sarnegoun'').{{sfn|Bonyadi et al|2017}}

European fritillaries had recently been documented in the wild amongst the [[Loire]] meadows in 1570 by Noël Capperon,{{efn|Noel Capperon (Natalis Caperon), was one of the victims of the [[St Bartholomew's Day massacre]] of [[Hugenots]] in Orleans in 1572. Although not formally trained in botany, he had an international reputation. In the late 1560s, [[Thomas Penny]], the English naturalist, came to visit him and study plant physiology.{{sfn|Egmond|2010}}}} an [[Orléans]] [[apothecary]], and which he had mentioned to [[Carolus Clusius|Clusius]] in correspondence in 1571, and sent him a specimen of these ''F. meleagris''. He also corresponded with Dodoens.{{sfn|Franchet|1885}} Capperon had suggested the name Fritillaria to Clusius, rather than the vernacular variegated lily (''Lilium ou bulbum variegatum''). He stated that the flower was known locally as Fritillaria because of a resemblance to the board used in playing checkers.{{efn|Letter from Capperon to Clusius, December 12, 1571: ''fritillaria ainsi appelions nous la plante que vous demandez pour ce les merques ou taches rouges et blanches sont que cees et posees en ordre comme sont celles de noz damiers et eschiquers aucunes pour ceste raison mesme luy donnent ces noms comme pyrgoides ou rhomboydes. Latruncularium''.{{sfn|Capperon|1571}} ''Dames'' is the French word for [[Checkers]] or Draughts}} In recognition of this, the [[botanical authority]] is sometimes written ''Fritillaria'' (Caperon) L.{{sfn|Griffiths|2015}}{{sfn|Raven|1947}}{{sfn|Egmond|2010}}

The first account in a botanical text is by Dodoens in his ''Purgantium'' (1574){{sfn|Dodoens|1574}} and in more detail in ''Stirpium'' (1583).{{sfn|Dodonaei|1583}} In the ''Purgantium'', Dodoens describes and illustrates ''F. meleagris'' as ''Meleagris flos'', without mentioning Capperon.<ref name=DodoPurg395/> He was also aware, through having been sent a picture, of ''F. imperialis'', and decided to include it as well, without making a connection. His term for ''F. imperialis'' was ''Corona imperialis''.<ref name=DodoPurg472/>{{sfn|Griffiths|2015}}

Consequently, Lobelius, in his ''Plantarum'' (1576), gives Dodoens the credit for describing ''F. meleagris''. He used the word "Fritillaria" for the first time, describing ''F. meleagris'', which he considered to belong to the ''Lilio-Narcissus'' plants, including tulips. The term ''Lilio-Narcissus'' refers to an appearance of having lily-like flowers, but a [[narcissus (plant)|narcissus]]-like bulb. He called it ''Fritillaria'' ([[synonyms]] ''Lilio-Narcissus purpurens variegatus'' or ''Meleagris flos Dodonaei'').<ref name=LobPlant65/> Lobelius also included amongst the lilies, but not as ''Fritillaria'', ''Corona imperialis'' which he mentions originated in Turkey and added what he referred to as ''Lilium persicum'' (''[[Fritillaria persica]]'').<ref name=LobPlant86/> In his later [[vernacular]] ''Kruydtboeck'' (1581) he described two species he considered related, Fritillaria ''Lilio-Narcissus purpurens variegatus'' and ''Lilio-Narcissus variegatus atropurpureus Xanctonicus''. He acknowledged that the plant had originally been found near Orleans and then sent to the Netherlands. ''Fritillaria is ook een soort van lelie narcis die de oorsprong heeft uit het land van Orléans van waar dat ze gebracht is in Nederland''.{{efn|Lobelius: Fritillaria is also a type of lily narcissus that originates from the land of Orléans from where it was brought to the Netherlands}} In his own language he referred to it as ''Fritillaria of heel bruin gespikkelde Lelie-Narcisse''.{{efn|Fritillaria, or the very brown speckled lily-narcissus}}<ref name=LobKru169/>{{sfn|Volkoomen|2017}} He also included ''Corona imperialis'' and ''Lilium persicum'' as before.<ref name=LobKru209/>

Dodoens had proposed the name ''Meleagris flos'' or [[Guinea-fowl]] flower, for what we now know as ''[[Fritillaria meleagris]]'', after a resemblance to that bird's spotted plumage, then known as ''Meleagris avis''. In the seventeenth century, [[John Parkinson (botanist)|John Parkinson]] provided an account of twelve species of what he referred to as ''Fritillaria'' - the checkered daffodil, in his ''Paradisus'' (1635), correctly placing it as closest to the [[lilies]]. He provides his version of Capperon's discovery, and suggests that some feel he should be honoured with the name ''Narcissus Caparonium''.{{sfn|Parkinson|1635}} Often when these exotic new plants entered the English language literature they lacked common names in the language. While [[Henry Lyte (botanist)|Henry Lyte]] can only describe ''F. meleagris'' as ''Flos meleagris'', ''Fritillaria'' or ''lilionarcissus'', it appears that it was [[Shakespeare]] who applied the common name of "chequered".{{sfn|Jacobson|2014}}

Although Clausius had corresponded with Capperon in 1571, he did not publish his account of European flora (other than Spain) till his ''Rariorum Pannoniam'' of 1583, where he gives an account of Capperon’s discovery, noting the names, Fritillaria, Meleagris and Lilium variegatum. However he did not consider ''F. imperialis'' or ''F. persica'' to be related, calling both of them ''Lilium'', ''Lilium persicum'' and ''Lilium susianum'' respectively.{{sfn|Clusius|1583}}

==== Post-Linnaean ====

Although the first formal description is attributed to [[Joseph Pitton de Tournefort]] in 1694,{{sfn|Tournefort|1694}}{{sfn|Tournefort|1719}} by convention, the first valid formal description is by [[Linnaeus]], in his ''[[Species Plantarum]]'' (1753),.{{sfn|Linnaeus|1753}} Therefore, the [[botanical authority]] is given as ''Tourn. ex L.''.{{sfn|WCSP|2017}} Linnaeus identified five known species of ''Fritillaria'', and grouped them in his ''Hexandria Monogynia'' (six [[stamens]]+one [[pistil]]), his [[Linnaen system|system]] being based on sexual characteristics. These characteristics defined the core group of the Liliaceae family for a long time. Linnaeus' original species were ''[[Fritillaria imperialis|F. imperialis]]'', ''F. regia'' (now ''[[Eucomis|Eucomis regia]]''), ''[[Fritillaria persica|F. persica]]'', ''[[Fritillaria pyrenaica|F. pyrenaica]]'' and ''[[Fritillaria meleagris|F. meleagris]]''. The Liliaceae [[family (biology)|family]] was first described by [[Michel Adanson]] in 1763, placing ''Fritillaria'' in section Lilia of that family, but also considering ''Imperialis'' as a separate genus to ''Fritillaria'', together with five other genera.<ref name=adansonLilia/> The formal description of the family is attributed to [[Antoine Laurent de Jussieu]] in 1789, who included eight genera, including ''Imperialis'', in his Lilia.<ref name=jussieuLilia/>

Although the [[circumscription (taxonomy)|circumscription]] of Liliaceae and its subdivisions have undergone considerable revision over the ensuing centuries, the close relationship between ''Fritillaria'' and ''Lilium''  the [[type genus]] of the family, have ensured that the former has remained part of the core group, which constitutes the modern much reduced family. For instance, [[Bentham and Hooker]] (1883),{{sfn|Bentham|Hooker|1862–1883}} placed ''Fritillaria'' and ''[[Lilium]]'' in Liliaceae tribe [[Tulipeae]], together with five other genera.

=== Phylogeny ===

''Fritillaria'' is a [[monophyletic]] genus, placed within the [[tribe (biology)|tribe]] [[Lilieae]] ''[[s.s.]]'', where it is a [[sister group]] to ''Lilium''{{sfn|Rønsted et al|2005}} and the largest member of that tribe.{{sfn|Peruzzi et al|2017}} The [[evolutionary]] and [[phylogenetic]] relationships between the genera currently included in [[Liliaceae]] are shown in the following [[Cladogram]]:

A large phylogenetic study of ''Lilium'' and ''Fritillaria'' has shown that ''Fritillaria'' consists of two distinct biogeographical clades (A and B), and that these are in a [[polytomous]] relationship with ''Lilium'', which could suggest ''Fritillaria'' is actually two distinct genera.{{sfn|Day et al|2014}}

=== Subdivision ===

The large number of species have traditionally been divided into a number of subgroupings.{{sfn|Rønsted et al|2005}} By 1828, [[Jean Étienne Duby|Duby]] in his treatment of the [[Flora]] of France, recognized two subgroups, which he called [[section (botany)|section]] ''Meleagris'' and section ''Petilium''.{{sfn|Duby|1828}} By 1874, [[J. G. Baker|Baker]] had divided 55 species into ten subgenera:{{sfn|Baker|1874}}

In the 1880s, both [[Bentham and Hooker]] (1883){{sfn|Bentham|Hooker|1862–1883}} and [[Pierre Edmond Boissier|Boissier]] (1884){{sfn|Boissier|1884}} independently simplified this by reducing nine of these subgenera to five, which they treated as [[Section (botany)|sections]] rather than subgenera. Bentham and Hooker, who recognized more than 50 species, transferred the tenth of Baker’s subgenera, ''Notholirion'' to ''Lilium''. Boissier, by contrast, in his detailed account of oriental species, recognized ''Notholirion'' as a separate genus, whose status has been maintained since (''see cladogram''). He also divided ''Eufritillaria'' into subsections.

In the post-[[Darwinian]] era, [[Vladimir Leontyevich Komarov|Komarov]] (1935){{sfn|Komarov|1935}} similarly [[segregate (taxonomy)|segregated]] ''Rhinopetalum'' and ''Korolkowia'' as separate genera, but Turrill and Sealy (1980){{sfn|Turrill|Sealy|1980}} more closely followed Boissier, but further divided ''Eufritillaria'' and placed all American species in ''Liliorhiza''. However, the best known and cited of these classification schemes based on [[plant morphology]] is that of [[Martyn Rix]],{{efn|Martyn Rix's PhD thesis at [[Cambridge University]] was on ''Fritillaria'',{{sfn|Rix|1971}}{{sfn|CUBG|2017}} and he is the [[botanical authority]] for 30 species of ''Fritillaria''{{sfn|Plantlist|2016}} }} produced by the Fritillaria Group of the [[Alpine Garden Society]]{{sfn|Fritillaria Group|2017}} in 2001.{{sfn|Rix|2001}} This listed 165 [[taxa]] grouped into 6 [[subgenera]], 130 [[species]], 17 [[subspecies]], and 9 [[Variety (botany)|varieties]].{{sfn|Karakas Metin et al|2013}} Rix, who described eight subgenera in all, restored both ''Rhinopetalum'' and ''Korolkowia'' as subgenera. He also used [[series (botany)|series]] to further subdivide subgenera, kept oissier’s four sections, renamed Eufritillaria as Fritillaria, and added subgenera ''Davidii'' and ''Japonica''. The largest of these is ''Fritillaria'', while ''Theresia'', ''Korolkowia'' and ''Davidii'' are [[monotypic]] (containing a single species).

Baker based his classification on the characteristics of the bulb, [[style (botany)|style]], [[nectary]] and [[capsule (botany)|capsule]] valves. The large nectaries of ''Fritillaria'' have been the focus of much of the morphological classification, while the distinct form of the nectaries in ''Rhinopetalum'' were the basis for considering it a separate genus.{{sfn|Rønsted et al|2005}}

==== Molecular phylogenetics ====

The development of [[molecular phylogenetics]] and [[cladistic analysis]] has allowed a better understanding of the infrageneric relationships of ''Fritillaria'' species. Initial studies showed the major infrageneric split to be by biogeographic region into two [[clades]], North America (clade A) and Eurasia (clade B). Clade A corresponded most closely with subgenus ''Liliorhiza''.{{sfn|Fay|Chase|2000}}

A subsequent study by [[Rønsted]] and colleagues (2005), using an expanded pool of taxa of 37 species including all of Rix’s subgenera and sections, confirmed the initial split on the basis of geography and supported the broad division of the genus into Rix's eight subgenera but not the deeper relationships (sections and series). Clade A corresponds with subgenus ''Liliorhiza'' centred in California, but a number of species (''[[Fritillaria camschatcensis|F. camschatcensis]]'' - Japan and Siberia), ''[[Fritillaria maximowiczii|F. maximowiczii]]'' and ''[[Fritillaria dagana|F. dagana]]'' - Russia) are also found in Western Asia. These Asian species form a [[evolutionary grade|grade]] with the true North American species, suggesting an origin in Asia followed by later dispersal. Of clade B, the Eurasian species, the largest subgenus, ''Fritillaria'', appeared to be [[polyphyletic]] in that ''[[Fritillaria pallidiflora|F. pallidiflora]]'' appeared to segregate in subclade B1, with subgenera ''Petillium'', ''Korolkowia'' and ''Theresia''  while all other species formed a clade within B2.{{sfn|Rønsted et al|2005}}

The phylogenetic, evolutionary and biogeographical relationships between the subgenera are shown in this [[cladogram]]:

The number of taxa sampled was subsequently enlarged to 92 species (66% of all species), and all species in each subgenus except ''Rhinopetalum'' (80%), ''Liliorhiza'' and ''Fritillaria'' (60%). This expanded study further resolved the evolutionary relationships between the subgenera but also confirmed the polyphyletic nature of subgenus ''Fritillaria'' as shown in the following cladogram. The majority of taxa within this subgenus (''Fritillaria'' 2) form a subclade centred in Europe, the Middle East and North Africa, but with some species ranging into China. The remainder (''Fritillaria'' 1), being centred in China and Central Asia, but with some species ranging into North and South Asia. This group is therefore probably a separate subgenus.{{sfn|Day et al|2012}}{{sfn|Day et al|2014}}

==== Subgenus ''Liliorhiza'' <small>(Kellog) Benth. & Hook.f.</small> ====

This subgenus of North American ''Fritillaria'', centred on Californis constitutes Clade A and contains more than 20 species. Thy have distinctive bulbs with several [[imbricate]] (overlapping) scales. Their resemblance to the bulbs of ''Lilium'' lends this subgenus the name of ''Liliorhiza'', or Liliy-roots. Most species exhibit loosrly attached [[bulbils]], whose size and shape gave them the name of "rice-grain bulbils". These are also seen in subgenus ''Davidii'', but appear to have evolved independently. Stem leaves are [[whorled]].{{sfn|Rønsted et al|2005}}{{sfn|Ryan|Simpson|2011}}

==== Subgenus ''Davidii'' <small>Rix</small> ====
{{main|Fritillaria davidii}}
This Chinese subgenus is monotypic for ''F. davidii''. It shares with ''Liliorhiza'' the presence of “rice-grain bulbils” but is distinguished from it by only having basal leaves, and no stem leaves.{{sfn|Rønsted et al|2005}}

|[[File:Berlin 20080423 Bluete orange Schlosspark Charlottenburg.jpg|thumb|130px|left|''[[Fritillaria imperialis]]''|alt=Flower of Fritillaria imperialis]]

==== Subgenus ''Petilium'' <small>(L.) Endl.</small> ====

Subgenus ''Petilium'' forms a subclade (B1), together with subgenera ''Korolkowia'' and ''Theresia''. It is a relatively small subgenus of four species characterized by large (up to 100&nbsp;cm) sturdy species, with bulbs that are much larger (up to 8&nbsp;cm) than most ''Fritillaria'' with a few large, erect, imbricate and fleshy scales. Flowers are 3–5 in a terminal [[umbel]], in the [[axils]] of the lower side of a leaf whorl. They have a [[:wiktionary:trifid|trifid]] (3 lobed) [[style (botany)|style]] and winged seeds. The subgenus is found in Turkey, Iraq, Turkestan, Iran, Baluchistan, Afghanistan, and the western [[Himalayas]]. The best known example is ''[[Fritillaria imperialis|F. imperialis]]'' (crown imperial).{{sfn|Rønsted et al|2005}}

{|
|[[File:Fritillaria japonica (flower s6).JPG|thumb|130px|left|''[[Fritillaria japonica]]''|alt=Flower of Fritillaria japonica]]

==== Subgenus ''Japonica'' <small>Rix</small> ====

''Japonica'' consists of eight species. [[Martyn Rix|Rix]] characterised the subgenus as follows: "Bulb of 2 or 3 solid scales, without rice grains; plants small and delicate; seeds pear-shaped, Erythronium-like, not flat; stem collapsing when seeds are ripe. Japanese woodland plants".

The species in this subgenus are dwarf fritillaries, [[endemic]] to Japan, bearing a single small campanulate flower on a slender stem with three linear [[verticillate]] (in one or more whorls) leaves at its top and two broader, oblong to elliptical and opposite leaves about 1&nbsp;cm below these. The flower is born on a short [[pedicel (botany)|pedicel]] amongst the leaves.{{sfn|Rønsted et al|2005}}{{sfn|Hill|2011}}

|[[File:Chequered Fritillaries (Fritillaria meleagris) (17208452561).jpg|thumb|130px|left|''[[Fritillaria meleagris]]|alt=Flower of Fritillaria meleagris]]

==== Subgenus ''Fritillaria'' ====

''Fritillaria'' is the largest subgenus, with about 100 species, or more than 70% of the total number of species in the genus, and includes the [[type species]], ''F. meleagris''.{{sfn|Rix|2001}} They are widely distributed from western Europe and the Mediterranean region to eastern Asia. Their characteristic is the ''Fritillaria''-type bulb. This consists of two fleshy more or less tunicated scales that are [[subglobose]]. The tunica is formed by the remains of previous years' scales, but sometimes the previous scales persist leading to more than two scales, sometimes three or four. The style may be trifid or undivided, or only trilobulate at the apex (a characteristic that was previously thought to divide the subgenus into sections).{{sfn|Rønsted et al|2005}}
|}

=== Species ===
 {{main|List of Fritillaria species}}
There are about 150 [[taxa]] (species and [[subspecies]]).{{sfn|Rix|Strange|2014}}{{sfn|Samaropoulou et al|2016}} Estimates of the number of species vary from about 100{{sfn|Ness|2003}} through 130{{sfn|FOC|2017}}–140.{{sfn|Day et al|2014}} [[The Plant List]] (2013) includes 141 accepted species names.{{sfn|TPL|2013}}

== Biogeography and evolution ==

It is likely that two invasions across the [[Bering Straits]] to North America took place within the Lileae, one in each genus, ''Lilium'' and ''Fritillaria''. Within the Eurasian clade, the two subclades differ in bulb type. In subclade B2 (''Fritillaria'', ''Rhinopetalum'', and ''Japonica''), the bulb type is described as Fritillaria-type, with 2–3 fleshy scales and the tunica derived from the remnants of previous year's scales. by contrast subclade B2 (''Petilium'', ''Theresia'' and ''Korolkowia'') differ. Those of ''Theresia'' and ''Korolkowia'' are large, consisting of a single large fleshy scale, while ''Petilium'' species have several large erect imbricate scales. In ''Liliorhiza'' the bulbs are naked and have nunerous scales similar to ''Lilium'', but with numerous "rice-grain bulbils". The location of the bulbils differ from the more common aerial pattern of arising from within the axil of a leaf or inflorecence, as in ''Lilium'' and ''Allium''. Similar bulbils are also found in ''Davidii''. These bulbils arise in the axils of the scale leaves. Bulbils confer an evolutionary advantage in [[vegetative propagation]]. {{sfn|Rønsted et al|2005}}

== Etymology ==

When Noel Capperon discovered ''F. meleagris'' growing in the Loire meadows in 1570, he wrote to Carolus Clusius, describing it, and saying that it was known locally as Fritillaria because the checkered pattern on the flower resembled the board on which checkers was played (''Dames'' in French). Clusius believed this to be an error, in that ''Fritillus'' is actually the Latin name for the box in which the dice used in the game were kept,{{sfn|Yates|1859}} not the board itself.{{sfn|Ellacombe|1895}}{{sfn|Clusius|1583}}{{sfn|OED|2017}}{{sfn|Botts|2017}} Some North American species are called "mission bells".

== Distribution and habitat ==

''Fritillaria'' are distributed in most [[temperate zone]] of the [[Northern Hemisphere]], from western [[North America]], through [[Europe]], the [[Mediterranean]], [[Middle East]] and [[Central Asia]] to China and Japan.{{sfn|Day et al|2014}}{{sfn|Türktaş et al|2012}}{{sfn|Rønsted et al|2005}}{{sfn|Brickell|2016}} [[Centres of diversity]] include Turkey (39 species){{sfn|Alp et al|2009}} and the [[Zagros Mountains]] of Iran (14–15 species).{{sfn|Bonyadi et al|2017}}{{sfn|Advay|Sharifi-Tehrani|2016}} Iran is also the centre of diversity of species such as ''F. imperialis'' and ''F. persica''.{{sfn|Ebrahimie et al|2006}} There are five areas of particularly active evolution and clustering of species - [[California]], Mediterranean Greece and Turkey, [[Anatolia]] and the Zagros mountains, central Asia from Uzbekistan to western [[Xinjiang]] and the eastern [[Himalayas]] in [[southwestern China]].{{sfn|Rix|Strange|2014}} ''Fritillaria'' species are found in a wide variety of [[climatic regions]] and [[habitats]], but about half of them show a preference for full sun in open habitats.{{sfn|Rønsted et al|2005}}

A number of ''Fritillaria'' are widely [[introduced species|introduced]]. Cultivated fritillaries (''F. meleagris'') have been recorded in British gardens since 1578, but only in the wild since 1736, it is likely to be [[introduced species|introduced]], rather than be [[endemic]]. It is greatly diminished there due to loss of habitat, although persistent along the [[Thames]] river in [[Oxfordshire]].{{sfn|Mabey|1996}}{{sfn|Byfield|2013}}{{sfn|Larkin|2011}} ''F. imperialis'' was introduced into Europe around the 1570s around the 1570s, with [[Ulisse Aldrovandi]] sending a drawing to [[Francesco de' Medici]] in [[Florence]], famed for his gardens at [[Villa di Pratolino]]  in 1578. His friend [[Jacopo Ligozzi]] (1547–1627) was also including it in his paintings, as well as ''F. persica''.{{sfn|Tomasi|Hirschauer|2002}} In Britain, ''F. imperialis'' was first seen in the London garden of James Nasmyth, surgeon to [[King James I]] in April 1605.{{sfn|Pavord|2005|loc=Chapter xx Note 9}}

==Ecology==

The majority of species are spring-flowering. Lily beetles ([[scarlet lily beetle]], ''Lilioceris lilii'' and ''[[Lilioceris |Lilioceris chodjaii]]''){{sfn|Ardakani|2014}} feed on fritillaries, and may become a [[pest (organism)|pest]] where these plants are grown in gardens or commercially.

== Conservation ==

A number of species of Fritillaria are [[endangered]], from over-harvesting, habitat fragmentation, over-grazing and international demand for herbals. These include many species in Greece,{{sfn|Samaropoulou et al|2016}} and ''[[Fritillaria gentneri]]'' in the pacific Northwest of North America.{{sfn|Gisler|Meinke|2003}} In Japan, five of the eight [[endemic]] species (subgenus ''Japonica'') are listed as endangered.{{sfn|Hill|2011}} In China, the collection of ''Fritillaria'' bulbs to make traditional medicine, particularly ''[[Fritillaria cirrhosa|F. cirrhosa]]'' from southwest China and the eastern Himalayas of Bhutan and Nepal and one of the most intensively harvested of the alpine medicinal plants, threatens [[extinction]].{{sfn|Day et al|2014}}

In Iran, ''F. imperialis'' and ''F. persica'' are endangered and ''F. imperialis'' is protected. The genus is threatened by irregular [[grazing]], change in [[pasture]] usage, [[pest (organism)|pest]] (primarily ''[[Lilioceris |Lilioceris chodjaii]]''){{sfn|Ardakani|2014}} migration from pasture destruction, and [[harvesting]] by poor people for sale to florists.{{sfn|Bonyadi et al|2017}}{{sfn|Ebrahimie et al|2006}}

== Toxicity ==

Most fritillaries contain poisonous [[alkaloid]]s such as [[imperialin]] and some may even be deadly if ingested in quantity.

==Uses==

The bulbs of a few species, such as ''[[Fritillaria affinis|F. affinis]]'', ''[[Fritillaria camschatcensis|F. camschatcensis]]'', and ''[[Fritillaria pudica|F. pudica]]'', are edible if prepared carefully. They were commonly eaten by indigenous peoples of the [[Pacific Northwest]] coast of North America.{{sfn|Turner|Kuhnlein|1983}} The wild species flowering in areas such as Iran have become important for [[ecotourism]], when in late May people come to the Valley of Roses, near [[Chelgerd]], to see ''[[Fritillaria imperialis|F. imperialis]]'' blooming.{{sfn|Badfar-Chaleshtori et al|2012}}{{sfn|Bonyadi et al|2017}} The area is also rich in ''[[Fritillaria reuteri|F. reuteri]]'' and ''[[Fritillaria gibbosa|F. gibbosa]]''.{{sfn|Lonely Planet|2017}}{{sfn|Greentours|2017}}
{{wide image|Imerial crown.jpg|1100px|''[[Fritillaria imperialis|F. imperialis]]'' blooming in [[Sepidan county|Sepidan]], in the [[Zagros Mountains]], Iran|alt=Panoramic view of Fritillaria imperialis blooming in the Zagros Mountains in Iran}} because of their large genome size, ''Fritillaria'' species are an important source for genomic studies of the proceeses involved in genome size diversity and evolution. They also have important commercial value both in horticulture and traditional medicine.{{sfn|Day et al|2014}}

=== Horticulture ===

Species of ''Fritillaria'' are becoming increasingly popular as [[ornamental garden plants]], and many species and [[cultivars]] are commercially available. They are usually grown from dormant bulbs planted in Autumn. As perennials they repeat flower every year, and some species will increase naturally. While Fritillaria is mainly harvested from the wild fields for commercial use, the growing price of the herbal product results in over-exploitation and puts the species at risk of depletion.{{sfn|Wang et al|2017}}

The following may be found in cultivation:-

=== Traditional medicine ===

Species of ''Fritillaria'' have been used in traditional medicine in China for over 2,000 years, and are one of the most widely used medicines today. The production of medicines from ''[[Fritillaria cirrhosa|F. cirrhosa]]'' is worth US $400 million per annum. Although some are cultivated for this purpose, most are gathered in the wild. In recent years demand has increased leading to over-harvesting of wild populations. In addition to China, ''Fritillaria'' products are used medicinally in the [[Himalayas]], including India, Nepal and Pakistan, as well as Japan, Korea and Southeast Asia. To meet the demand additional countries such as Turkey and Burma are involved in the collection. The products are used mainly as [[antitussives]], [[expectorants]], and [[antihypertensives]]. The active ingredients are thought to be isosteroidal and [[steroidal alkaloid]] compounds. Chinese sources suggest 16 species as source material, but this may be an overestimate due to the large number of synonyms in Chinese. Of these, 15 are in subgenus ''Fritillaria'' (both subclades), but one (''[[Fritillaria anhuiensis|F. anhuiensis]]'') is in subgenus ''Liliorhiza''.{{sfn|Day et al|2014}}{{sfn|Karakas Metin et al|2013}}{{sfn|Wang et al|2017}} ''F. imperialis'' also has a long history of medicinal usage in China and Iran.{{sfn|Bonyadi et al|2017}}
[[File:干川贝母.jpg|thumb|Dried bulbs of ''[[fritillaria cirrhosa|F. cirrhosa]]''|alt=Group of died bulbs of Fritillaria cirrhosa being prepared for making traditional medicine]]
Fritillaria extracts (fritillaria in English, ''[[bulbus fritillariae cirrhosae]]'' in Latin){{sfn|Lenz|Frey|2005}} are used in [[traditional Chinese medicine]] under the name ''chuan bei mu'' (literally "Shell mother from Sichuan",{{sfn|Lenz|Frey|2005}} or just ''beimu''). Species such as ''F. cirrhosa'' and ''[[Fritillaria verticillata|F. verticillata]]'' are used in cough remedies.{{sfn|Zhang et al|2010}} They are listed as ''chuān bèi'' ({{zh|c=川貝/川贝}}) or ''zhè bèi'' (Chinese: 浙貝/浙贝), respectively, and are often in formulations combined with extracts of [[loquat]] (''Eriobotrya japonica''). ''Fritillaria verticillata'' bulbs are also traded as ''bèi mǔ'' or, in [[Kampō]], ''baimo'' (Chinese/[[Kanji]]: 貝母, [[Katakana]]: バイモ). In one study fritillaria reduced airway inflammation by suppressing [[cytokine]]s, [[histamine]]s, and other compounds of inflammatory response.{{sfn|Yeum et al|2007}}{{sfn|Wang et al|2017}}

== {{anchor|Culture}}Popular culture ==

[[Shakespeare]], [[Matthew Arnold]] and [[George Herbert]] and more recently [[Vita Sackville-West]] (''The Land'' 1927) wrote romantically about fritillaries.{{sfn|Scarry|2016}}{{sfn|Ellacombe|1895}}{{sfn|Byfield|2013}} Fritillaries were also a favourite of the Dutch flower painters that emerged around 1600, such as [[Ambrosius Bosschaert]]{{sfn|van Berkel|2010}} and [[Jacob de Gheyn II]],{{sfn|Boom|1975}} and appeared in Italian art, such as that of [[Jacopo Ligozzi]] in the late sixteenth century.{{sfn|Tomasi|Hirschauer|2002}}
[[File:AUT Großsteinbach COA.png|thumb|[[Coat of arms]] of [[Großsteinbach]], Austria|alt=Coat of arms of Großsteinbach in Austria, depicting a stylised flower of Fritillaria meleagris]]
Fritillaries are commonly used as [[floral emblem]]s. ''[[F. meleagris]]'' (snake's head fritillary) is the county flower of [[Oxfordshire]], UK, and the [[Province flowers of Sweden|provincial flower]] of [[Uppland]], Sweden, where it is known as ''kungsängslilja'' ("[[Kungsängen]] lily").{{sfn|Volkoomen|2017}} In Germany, ''F. meleagris'' appears as a heraldic device in a number of municipalities, such as [[Hetlingen]], [[Seestermühe]] and [[Winseldorf]], and also in Austria ([[Großsteinbach]]). In [[Croatia]] this species is known as ''kockavica'', and the checkerboard pattern of its flowers may have inspired the ''šahovnica'' pattern on the nation's [[Coat of arms of Croatia|coat of arms]]. ''F. camschatcensis'' (Kamchatka fritillary) is the floral emblem of [[Ishikawa Prefecture]] and [[Obihiro, Hokkaidō|Obihiro City]] in Japan. Its Japanese name is ''kuroyuri'' (クロユリ), meaning "dark lily". ''[[Fritillaria montana]]'' is the floral emblem of [[Giardino Botanico Alpino di Pietra Corva]], a [[botanical garden]] in Italy.{{sfn|Pietra Corva|2017}}
