Fritillaria(fritillaries) is agenusof spring floweringherbaceousbulbousperennialplants in the lilyfamily(Liliaceae). Thetype species,Fritillaria meleagris,was first described in Europe in 1571, while other species from the Middle East and Asia were alsointroducedto Europe at that time. The genus has about 130–140speciesdivided among eightsubgenera.The flowers are usually solitary, nodding and bell-shaped with bulbs that have fleshy scales, resembling those oflilies.They are known for their largegenome sizeand genetically are very closely related to lilies. They arenativeto thetemperate regionsof theNorthern hemisphere,from theMediterraneanandNorth AfricathroughEurasiaand southwest Asia to westernNorth America.Many areendangereddue to enthusiastic picking.

The nameFritillariais thought to refer to the checkered pattern ofF. meleagris,resembling a box in whichdicewere carried. Fritillaries are commercially important inhorticultureasornamental garden plantsand also intraditional Chinese medicine,which is also endangering some species.Fritillariaflowers have been popular subjects for artists to depict and as emblems of regions and organizations.

General

[edit]

Fritillariais agenusofperennialherbaceousbulbiferousgeophytes,dying back after flowering to an underground storage bulb from which they regrow in the following year.[3]It ischaracterisedby nodding (pendant) flowers,perianthscampanulate(bell- or cup-shaped) with erect segments in upper part, anectarialpit, groove or pouch at the base of thetepal,anthersusually pseudobasifixed, rarely versatile,fruitsometimes winged,embryominute.[4]

Specific

[edit]

Vegetative

[edit]
Bulbs

The bulbs are typically tunicate, consisting of a few tightly packed fleshy scales with a translucenttunicthat disappears with further growth of the bulb. However, some species (F. imperialis,F. persica) have naked bulbs with many scales and loosely attachedbulbils,resembling those of the closely relatedLilium,[5]althoughF. persicahas only a single scale.[4]

Stems and leaves

The stems have few or manycaulineleaves(arising from the stem) that areoppositeon the stem orverticillate(arranged inwhorls), sometimes with acirrhoseapex (ending in atendril).[4]

Reproductive

[edit]
Inflorescence and flowers

Theinflorescencebearsflowersthat are often solitary and nodding, but some formumbelsor haveracemeswith many flowers. The flowers are usuallyactinomorphic(radially symmetric), but weakly zygomorphic (single plane of symmetry) inF. gibbosaandF. ariana.[6]The campanulate perianth has sixtepals,in two free whorls of three (trimerous), that can be white, yellow, green, purple or reddish. The erect segments are usuallytesselatedwith squares of alternating light and dark colours. While the tepals are usually the same size in both whorls, inF. pallidiflora,the outer tepals are wider. The tepals have nectarial pits, grooves (F. sewerzowii) or pouches at their base. InF. persicathe nectarial pouch is developed into a short spur. Theperigonalnectariesare large and well developed, and in most species (with the exception of subgenusRhinopetalum), are linear tolanceolateorovateand weakly impressed upon the tepals.[4]

Gynoecium

The flowers arebisexual,containing both male (androecium) and female (gynoecium) characteristics. Thepistilhas three carpels (tricarpellary). Theovariesare hypogynous (superior, that is attached above the other floral parts). Theovuleisanatropousin orientation and has twointeguments(bitegmic), themicropyle(opening) being formed from the inner integument, while thenucellusis small. Theembryo sacor megagametophyte is tetrasporic, in which all fourmegasporessurvive. Thestyleis trilobate to trifid (in 3 parts) and the surface of thestigmais wet.[4]

Androecium

Stamensare six, in two trimerous whorls of three, and diplostemonous (outer whorl of stamens opposite outer tepals and the inner whorl opposite inner tepals). Filamentsfiliformor slightly flattened, but sometimespapilloseand rarely hairy (F. karelinii). Anthers are linear to ellipsoid, but rarelysubglobose(F. persica) in shape, and their attachment to the filament is usually pseudobasifixed (connective tissue extends in a tube around the filament tip), rarely attached at the centre and free (dorsifixed versatile;F. fuscaand someLiliorhizaspecies). In contrast, pseudobasifixed anthers can not move freely. Thepollengrains are spheroidal and reticulate (net like pattern), with individual brochi (lumina within reticulations) of 4–5 μm.[4]

Fruit and seeds

Thecapsuleis obovoid to globose,loculicidaland six-angled, sometimes with wings. Theseedsare flattened with a marginal wing, the seed coat made out of both integuments, but the testa is thin and theendospermlacks starch. Theembryois small.[4][7]

Phytochemistry

[edit]

Fritillaria, like other members of the family Liliaceae, containflavonol glycosidesand tri- anddiferulic-acidsucrose esters,[4]steroidal alkaloids,saponinsandterpenoidsthat have formed the active ingredients in traditional medicine (seeTraditional medicine).[8]Certain species have flowers that emit disagreeable odors that have been referred to as phenolic, putrid, sulfurous, sweaty and skunky.[9]ThescentofFritillaria imperialishas been called "rather nasty", while that ofF. agrestis,known commonly as stink bells, is reminiscent ofcanine feces.On the other hand,F. striatahas a sweet fragrance.[10]The "foxy" odor ofF. imperialishas been identified as 3-methyl-2-butene-1-thiol (dimethylallyl mercaptan), analkylthiol.[11]

Genome

[edit]

Fritillariarepresents one of the most extreme cases ofgenomesize expansion inangiosperms.Polyploidyis rare, with nearly all species beingdiploidand only occasional reports of triploidy.[3]Reportedgenome sizeinFritillariavary from1Cx(DNAcontent of unreplicatedhaploidchromosome complement) values of 30.15 to 85.38 Gb (Gigabase pairs), that is > 190 times that ofArabidopsis thaliana,which has been called the "model plant"[3]and > 860 times that ofGenlisea aurea,which represents the smallest land plant genomesequencedto date.[12]Giant genome size is generally defined as >35 pg (34 Gb).[13]The largest genomes in diploidFritillariaare found in subgenusJaponica,exceeding 85 Gb.[3]At least one species, tetraploidF. assyriaca,has a very large genome. With approximately 127pg(130 Gb), it was for a long time the largest known genome, exceeding the largestvertebrateanimal genome known to date, that of themarbled lungfish(Protopterus aethiopicus), in size.[14]Heterochromatinlevels vary bybiogeographicregion, with very little inOld Worldand abundant levels inNew Worldspecies. Most species have a basicchromosome numberof x=12, but x=9, 11 and 13 have been reported.[5]

Taxonomy

[edit]

History

[edit]

Pre-Linnaean

[edit]

Gerard(1597) states thatFritillariawas unknown to theancients,[15]but certainly it was appearing in the writings of sixteenth century European botanists, includingDodoens(1574, 1583),[16][17]Lobelius(1576, 1581),[18][19]andClusius(1583)[20]in addition to Gerard, and was mentioned byShakespeareand other authors of the period (seeCulture).[21]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 developingbotanical gardensof Europe.[22]By the middle of the sixteenth century there was already a flourishing export trade of various bulbs from Turkey to Europe.[23]In Persia, the first mention in the literature was by Hakim Mo'men Tonekabon in hisTohfe Al-Mo'meninin 1080AH(c. 1669AD), who described the medicinal properties ofF. imperialis(laleh sarnegoun).[24]

European fritillaries were documented in the wild amongst theLoiremeadows in 1570 by Noël Capperon,[b]anOrléansapothecary.He mentioned them toClusiusin correspondence in 1571, and sent him a specimen ofF. meleagris.He also corresponded with Dodoens.[26]Capperon 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.[c]In recognition of this, thebotanical authorityis sometimes writtenFritillaria(Caperon) L.[28][29][25]

The first account in a botanical text is by Dodoens in hisPurgantium(1574)[16]and in more detail inStirpium(1583).[17]In thePurgantium,Dodoens describes and illustratesF. meleagrisasMeleagris flos,without mentioning Capperon.[30]He was also aware, through having been sent a picture, ofF. imperialis,and decided to include it as well, without making a connection. His term forF. imperialiswasCorona imperialis.[31][28]

Consequently, Lobelius, in hisPlantarum(1576), gives Dodoens the credit for describingF. meleagris.He used the word "Fritillaria" for the first time, describingF. meleagris,which he considered to belong to theLilio-Narcissusplants, including tulips. The termLilio-Narcissusrefers to an appearance of having lily-like flowers, but anarcissus-like bulb. He called itFritillaria(synonymsLilio-Narcissus purpurens variegatusorMeleagris flos Dodonaei).[32]Lobelius also included amongst the lilies, but not asFritillaria,Corona imperialiswhich he mentions originated in Turkey and added what he referred to asLilium persicum(Fritillaria persica).[33]In his latervernacularKruydtboeck(1581) he described two species he considered related, FritillariaLilio-Narcissus purpurens variegatusandLilio-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.[d]In his own language he referred to it asFritillaria of heel bruin gespikkelde Lelie-Narcisse.[e][34][35]He also includedCorona imperialisandLilium persicumas before.[36]

Dodoens had proposed the nameMeleagris flosorGuinea-fowlflower, for what we now know asFritillaria meleagris,after a resemblance to that bird's spotted plumage, then known asMeleagris avis.In the seventeenth century,John Parkinsonprovided an account of twelve species of what he referred to asFritillaria- the checkered daffodil, in hisParadisus(1635), correctly placing it as closest to thelilies.He provides his version of Capperon's discovery, and suggests that some feel he should be honoured with the nameNarcissus Caparonium.[37]Often when these exotic new plants entered the English language literature they lacked common names in the language. WhileHenry Lytecan only describeF. meleagrisasFlos meleagris,Fritillariaorlilionarcissus,it appears that it wasShakespearewho applied the common name of "chequered".[38]

Although Clausius had corresponded with Capperon in 1571, he did not publish his account of European flora (other than Spain) till hisRariorum Pannoniamof 1583, where he gives an account of Capperon's discovery, noting the names, Fritillaria, Meleagris and Lilium variegatum. However he did not considerF. imperialisorF. persicato be related, calling both of themLilium,Lilium persicumandLilium susianumrespectively.[20]

Post-Linnaean

[edit]

Although the first formal description is attributed toJoseph Pitton de Tournefortin 1694,[39][40]by convention, the first valid formal description is byLinnaeus,in hisSpecies Plantarum(1753),.[1]Therefore, thebotanical authorityis given asTourn. ex L..[2]Linnaeus identified five known species ofFritillaria,and grouped them in hisHexandria Monogynia(sixstamens+onepistil), hissystembeing based on sexual characteristics. These characteristics defined the core group of the family Liliaceae for a long time. Linnaeus' original species wereF. imperialis,F. regia(nowEucomis regia),F. persica,F. pyrenaicaandF. meleagris.ThefamilyLiliaceae was first described byMichel Adansonin 1763, placingFritillariain section Lilia of that family, but also consideringImperialisas a separate genus toFritillaria,together with five other genera.[41]The formal description of the family is attributed toAntoine Laurent de Jussieuin 1789, who included eight genera, includingImperialis,in his Lilia.[42]

Although thecircumscriptionof Liliaceae and its subdivisions have undergone considerable revision over the ensuing centuries, the close relationship betweenFritillariaandLiliumthetype genusof 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),[43]placedFritillariaandLiliumin Liliaceae tribeTulipeae,together with five other genera.

Phylogeny

[edit]

Fritillariais generally considered amonophyleticgenus, placed within thetribeLilieaes.s.,where it is asister grouptoLilium[5]and the largest member of that tribe.[44]Theevolutionaryandphylogeneticrelationships between the genera currently included inLiliaceaeare shown in the followingCladogram:

More recently, some larger phylogenetic studies of Lilieae,LiliumandFritillariahave suggested thatFritillariamay actually consist of two distinct biogeographical clades (A and B), and that these are in apolytomousrelationship withLilium.This could mean thatFritillariais actually two distinct genera, suggesting that the exact relationship is not yet fully resolved.[3][53]

The large number of species have traditionally been divided into a number of subgroupings.[5]By 1828,Dubyin his treatment of thefloraof France, recognized two subgroups, which he calledsectionMeleagrisand sectionPetilium.[54]By 1874,Bakerhad divided 55 species into ten subgenera:[55]

In the 1880s, bothBentham and Hooker(1883)[43]andBoissier(1884)[56]independently simplified this by reducing nine of these subgenera to five, which they treated assectionsrather than subgenera. Bentham and Hooker, who recognized more than 50 species, transferred the tenth of Baker's subgenera,NotholiriontoLilium.Boissier, by contrast, in his detailed account of oriental species, recognizedNotholirionas a separate genus, whose status has been maintained since (see cladogram). He also dividedEufritillariainto subsections.

In the post-Darwinianera,Komarov(1935)[57]similarlysegregatedRhinopetalumandKorolkowiaas separate genera, but Turrill and Sealy (1980)[58]more closely followed Boissier, but further dividedEufritillariaand placed all American species inLiliorhiza.However, the best known and cited of these classification schemes based onplant morphologyis that ofMartyn Rix,[f]produced by the Fritillaria Group of theAlpine Garden Society[62]in 2001.[63]This listed 165taxagrouped into 6subgenera,130species,17subspecies,and 9varieties.[64]Rix, who described eight subgenera in all, restored bothRhinopetalumandKorolkowiaas subgenera. He also usedseriesto further subdivide subgenera, kept Boissier's four sections, renamedEufritillariaasFritillaria,and added subgeneraDavidiiandJaponica.The largest of these isFritillaria,whileTheresia,KorolkowiaandDavidiiaremonotypic(containing a single species).

Baker based his classification on the characteristics of the bulb,style,nectaryandcapsulevalves. The large nectaries ofFritillariahave been the focus of much of the morphological classification, while the distinct form of the nectaries inRhinopetalumwere the basis for considering it a separate genus.[5]

Molecular phylogenetics

[edit]

The development ofmolecular phylogeneticsandcladistic analysishas allowed a better understanding of the infrageneric relationships ofFritillariaspecies. Initial studies showed the major infrageneric split to be by biogeographic region into twoclades,North America (clade A) and Eurasia (clade B). Clade A corresponded most closely with subgenusLiliorhiza.[67]

A subsequent study byRønstedand 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 subgenusLiliorhizacentred in California, but a number of species (F. camschatcensis- Japan and Siberia),F. maximowicziiandF. dagana- Russia) are also found in Western Asia. These Asian species form agradewith 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 bepolyphyleticin thatF. pallidifloraappeared to segregate in subclade B1, with subgeneraPetillium,KorolkowiaandTheresiawhile all other species formed a clade within B2.[5]

The phylogenetic, evolutionary and biogeographical relationships between the subgenera are shown in thiscladogram:

The number of taxa sampled was subsequently enlarged to 92 species (66% of all species), and all species in each subgenus exceptRhinopetalum(80%),LiliorhizaandFritillaria(60%). This expanded study further resolved the evolutionary relationships between the subgenera but also confirmed the polyphyletic nature of subgenusFritillariaas shown in the following cladogram. The majority of taxa within this subgenus (Fritillaria2) form a subclade centred in Europe, the Middle East and North Africa, but with some species ranging into China. The remainder (Fritillaria1), 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.[68][3]

SubgenusLiliorhiza(Kellog) Benth. & Hook.f.

[edit]

This subgenus of North AmericanFritillaria,centred on California constitutes Clade A and contains more than 20 species. They have distinctive bulbs with severalimbricate(overlapping) scales. Their resemblance to the bulbs ofLiliumlends this subgenus the name ofLiliorhiza,or lily-roots. Most species exhibit loosely attachedbulbils,whose size and shape gave them the name of "rice-grain bulbils". These are also seen in subgenusDavidii,but appear to have evolved independently. Stem leaves arewhorled.[5][69]

SubgenusPetilium(L.) Endl.

[edit]

SubgenusPetiliumforms a subclade (B1), together with subgeneraKorolkowiaandTheresia.It is a relatively small subgenus of four species characterized by large (up to 100 cm) sturdy species, with bulbs that are much larger (up to 8 cm) than mostFritillariawith a few large, erect, imbricate and fleshy scales. Flowers are 3–5 in a terminalumbel,in theaxilsof the lower side of a leaf whorl. They have atrifid(3 lobed)styleand winged seeds. The subgenus is found in Turkey, Iraq, Turkestan, Iran, Baluchistan, Afghanistan, and the westernHimalayas.The best known example isF. imperialis(crown imperial).[5]

The species in this subgenus are dwarf fritillaries,endemicto Japan, bearing a single small campanulate flower on a slender stem with three linearverticillate(in one or more whorls) leaves at its top and two broader, oblong to elliptical and opposite leaves about 1 cm below these. The flower is born on a shortpedicelamongst the leaves.[5][70]

Flower of Fritillaria meleagris
Fritillaria meleagris

SubgenusFritillaria

[edit]

Fritillariais the largest subgenus, with about 100 species, or more than 70% of the total number of species in the genus, and includes thetype species,F. meleagris.[63]They are widely distributed from western Europe and the Mediterranean region to eastern Asia. Their characteristic is theFritillaria-type bulb. This consists of two fleshy more or less tunicated scales that aresubglobose.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).[5]

Species

[edit]

The genusFritillariaincludes about 150 subordinatetaxa,including species andsubspecies.[71][72]Estimates of the number of species vary from about 100[73]through 130[74]–140.[3]The Plant List(2013) includes 141 accepted species names, and 156 taxa in total.[75]

Biogeography and evolution

[edit]

It is likely that two invasions across theBering Straitsto North America took place within the Lileae, one in each genus,LiliumandFritillaria.Within the Eurasian clade, the two subclades differ in bulb type. In subclade B2 (Fritillaria,Rhinopetalum,andJaponica), 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,TheresiaandKorolkowia) differ. Those ofTheresiaandKorolkowiaare large, consisting of a single large fleshy scale, whilePetiliumspecies have several large erect imbricate scales. InLiliorhizathe bulbs are naked and have numerous scales similar toLilium,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 inflorescence, as inLiliumandAllium.Similar bulbils are also found inDavidii.These bulbils arise in the axils of the scale leaves. Bulbils confer an evolutionary advantage invegetative propagation.[5]

Etymology

[edit]

When Noël Capperon, anOrléansapothecary,[76]discoveredF. meleagrisgrowing in theLoiremeadows in 1570, he wrote toCarolus Clusius,describing it, and saying that it was known locally asfritillaria,supposedly because the checkered pattern on the flower resembled the board on whichcheckerswas played. Clusius believed this to be an error, in thatfritillusis actually the Latin name for the box in which the dice used in the game were kept,[77]not the board itself.[78][20][79][80]

Some North American species are called "mission bells".

Distribution and habitat

[edit]

Fritillariaare distributed in mosttemperate zoneof theNorthern Hemisphere,from westernNorth America,throughEurope,theMediterranean,Middle EastandCentral Asiato China and Japan.[3][81][5][82]Centres of diversityinclude Turkey (39 species)[83]and theZagros Mountainsof Iran (14–15 species).[24][84]Iran is also the centre of diversity of species such asF. imperialisandF. persica.[85]There are five areas of particularly active evolution and clustering of species -California,Mediterranean Greece and Turkey,Anatoliaand the Zagros mountains, central Asia from Uzbekistan to westernXinjiangand the easternHimalayasinsouthwestern China.[71]Fritillariaspecies are found in a wide variety ofclimatic regionsandhabitats,but about half of them show a preference for full sun in open habitats.[5]

A number ofFritillariaare widelyintroduced.Cultivated fritillaries (F. meleagris) have been recorded in British gardens since 1578, but only in the wild since 1736, it is likely to beintroduced,rather than beendemic.It is greatly diminished there due to loss of habitat, although persistent along the RiverThamesinOxfordshire.[86][87][88]F. imperialiswas introduced into Europe around the 1570s, withUlisse Aldrovandisending a drawing toFrancesco de' MediciinFlorence,famed for his gardens atVilla di Pratolinoin 1578. His friendJacopo Ligozzi(1547–1627) was also including it in his paintings, as well asF. persica.[89]In Britain,F. imperialiswas first seen in the London garden of James Nasmyth, surgeon toKing James Iin April 1605.[90]

Ecology

[edit]

The majority of species are spring-flowering. Lily beetles (scarlet lily beetle,Lilioceris liliiandLilioceris chodjaii) feed on fritillaries, and may become apestwhere these plants are grown in gardens or commercially.[91]

Fritillaria areentomophilous(insect pollinated). Those species with large nectaries (4–12 x 1–4 mm) and have morefructosethanglucosein thenectarare most commonly pollinated bywasps,while those with smaller nectaries (2–10 x 1–2 mm) and a more balanced nectar composition are most commonly pollinated bybumblebees.[4]

A number of species of Fritillaria areendangered,fromover-harvesting,habitat fragmentation, over-grazing and international demand for herbals. These include many species in Greece,[72]andFritillaria gentneriin the pacific Northwest of North America.[92]In Japan, five of the eightendemicspecies (subgenusJaponica) are listed as endangered.[70]In China, the collection ofFritillariabulbs to make traditional medicine, particularlyF. cirrhosafrom southwest China and the eastern Himalayas of Bhutan and Nepal and one of the most intensively harvested of the alpinemedicinal plantsthreatensextinction.[3]

In Iran,F. imperialisandF. persicaare endangered andF. imperialisis protected. The genus is threatened by irregulargrazing,change inpastureusage,pest(primarilyLilioceris chodjaii)[91]migration from pasture destruction, andharvestingby poor people for sale to florists.[24][85]

One species,F. delavayi,has begun to grow brown, greyish flowers to better camouflage amongst the rock of its habitat. Scientists believe it is evolving to combat its biggest predator — humans. Over-picking has greatly decreased the availability of this species in China and even though there is no known difference between the flowers picked in the wild and those grown commercially, hunters continue to believe the wild flowers offer better medicinal benefit.[93]

Toxicity

[edit]

Most fritillaries contain poisonous steroidalalkaloidssuch asimperialinin the bulbs and some may even be deadly if ingested in quantity.[4]

Uses

[edit]

The bulbs of a few species, such asF. affinis,F. camschatcensis,andF. pudica,are edible if prepared carefully. They were commonly eaten by indigenous peoples of thePacific Northwestcoast of North America.[94]The wild species flowering in areas such as Iran have become important forecotourism,when in late May people come to the Valley of Roses, nearChelgerd,to seeF. imperialisblooming.[95][24]The area is also rich inF. reuteriandF. gibbosa.[96][97]

Because of their large genome size,Fritillariaspecies are an important source for genomic studies of the processes involved in genome size diversity and evolution. They also have important commercial value both in horticulture and traditional medicine.[3]

Horticulture

[edit]

Species ofFritillariaare becoming increasingly popular asornamental garden plants,and many species andcultivarsare 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. WhileFritillariais 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.[98]

The following may be most commonly found in cultivation:-

Traditional medicine

[edit]

Species ofFritillariahave been used in traditional medicine in China for over 2,000 years, and are one of the most widely used medicines today.[8]The production of medicines fromF. cirrhosais 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,Fritillariaproducts are used medicinally in theHimalayas,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 asantitussives,expectorants,andantihypertensives.The active ingredients are thought to be isosteroidal andsteroidal alkaloidcompounds. 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 subgenusFritillaria(both subclades), but one (F. anhuiensis) is in subgenusLiliorhiza.[3][64][98]F. imperialisalso has a long history of medicinal usage in China and Iran.[24]

Fritillaria extracts (fritillaria in English,bulbus fritillariae cirrhosaein Latin)[99]are used intraditional Chinese medicineunder the namechuan bei mu(literally "Shell mother from Sichuan",[99]or justbeimu). Species such asF. cirrhosa,F. thunbergiiandF. verticillataare used in cough remedies.[100][8]They are listed aschuān bèi(Chinese:Xuyên bối / xuyên bối) orzhè bèi(Chinese: Chiết bối / chiết bối ), respectively, and are often in formulations combined with extracts ofloquat(Eriobotrya japonica).Fritillaria verticillatabulbs are also traded asbèi mǔor, inKampō,baimo(Chinese/Kanji:Bối mẫu,Katakana:バイモ). In one study fritillaria reduced airway inflammation by suppressingcytokines,histamines,and other compounds of inflammatory response.[101][98]

Shakespeare,Matthew ArnoldandGeorge Herbertand more recentlyVita Sackville-West(The Land1927) wrote romantically about fritillaries.[21][78][87]Fritillaries were also a favourite of the Dutch flower painters that emerged around 1600, such asAmbrosius Bosschaert[102]andJacob de Gheyn II,[103]and appeared in Italian art, such as that ofJacopo Ligozziin the late sixteenth century.[89]

Fritillaries are commonly used asfloral emblems.F. meleagris(snake's head fritillary) is the county flower ofOxfordshire,UK, and theprovincial flowerofUppland,Sweden, where it is known askungsängslilja( "Kungsängenlily ").[35]In Germany,F. meleagrisappears as a heraldic device in a number of municipalities, such asHetlingen,SeestermüheandWinseldorf,and also in Austria (Großsteinbach).

InCroatiathis species is known askockavica(fromkocka,lit.'cube'), and the checkerboard pattern of its flowers may have inspired thecheckerboard pattern on the nation's coat of arms.F. camschatcensis(Kamchatka fritillary) is the floral emblem ofIshikawa PrefectureandObihiro Cityin Japan. Its Japanese name iskuroyuri(クロユリ), meaning "dark lily".Fritillaria montanais the floral emblem ofGiardino Botanico Alpino di Pietra Corva,abotanical gardenin Italy.[104]
