Шаблон:Short description Шаблон:Use dmy dates Шаблон:Automatic taxobox
Allioideae is a subfamily of monocot flowering plants in the family Amaryllidaceae, order Asparagales. It was formerly treated as a separate family, Alliaceae.Шаблон:Sfn The subfamily name is derived from the generic name of the type genus, Allium. It is composed of about 18 genera.
Description
The subfamily contains both well-known garden plants and weeds, such as Nothoscordum.Шаблон:Sfn
Taxonomy
When Linnaeus formerly described the type genus Allium in his Species Plantarum in 1753,Шаблон:Sfn thirty species had this name. He placed Allium in a grouping he referred to as Hexandria monogynia (i.e. six stamens and one pistil)Шаблон:Sfn containing 51 genera in all.Шаблон:Sfn
In 1763, Michel Adanson, who proposed the concept of families of plants, included Allium and related genera as a grouping within LiliaceaeШаблон:Sfn as Section IV, Les Oignons (Onions), or Cepae in Latin.Шаблон:Sfn De Jussieu is officially recognised as the first formal establishment of the suprageneric grouping into families (Ordo) in 1789. In this system Allium was one of fourteen genera in Ordo VI, Asphodeles (Asphodeli), of the third class (Stamina epigyna) of Monocots.Шаблон:Sfn
In 1786, the Allioideae were first described by their type genus as Alliaceae by Batsch.Шаблон:Sfn In 1797, after the appearance of the Jussieu system, this was validated by Borkhausen.Шаблон:Sfn Jean Henri Jaume Saint-Hilaire (1805), who developed the concept of Amaryllidaceae, continued Jussieu's treatment of Allium under Asphodeli (which he considered synonymous with Adanson's Liliaceae and Jussieu's Asphodeli).Шаблон:Sfn He placed Allium in an unnamed monotypic section of Asphodeli defined as Fleurs en ombelle, racine bulbeuse. Calice à six parties egales (umbellate flowers, bulbous, calyx of six equal parts).Шаблон:Sfn
Subsequently, de Candolle reverted the family name back to Liliaceae from Asphodeli.Шаблон:Sfn He divided the Liliaceae into a series of Ordres, and the second ordre was named Asphodèles, based on Jussieus' family of that name,Шаблон:Sfn in which he placed Allium.Шаблон:Sfn The term 'Alliaceae' then reappeared in its subfamilial form, Allieae, in Dumortier's Florula Belgica (1827),Шаблон:Sfn with six genera.
The 'Alliaceae' have been treated as Allieae within the family Liliaceae (or Aspholecaceae, a partial synonym) by most authorities since. In 1830, Lindley, the first English systematist, considered AlliaceaeШаблон:Refn to be part of the tribe Asphodeleae,Шаблон:Sfn separating them from the Liliaceae as he understood them. He also described the closely related Gilliesieae (p. 274), which with the Allieae would later migrate to Amaryllidaceae.By the time of his final work in 1846 he realised that the Liliaceae, which had expanded greatly were very diverse in circumscription with many subdivisions, and were already paraphyletic ("catch-all"). He absorbed Asphodeleae into this family and created a suborder of Scilleae, which he considered equivalent to Link's Allieae.Шаблон:Sfn
By the time of the next major British (though written in Latin) classification, that of Bentham and Hooker (1883), the Allieae had become one of 20 tribes within Liliaceae.Шаблон:Sfn The Allieae included Lindley's GilliesieaeШаблон:Sfn as one of its four subtribes.Шаблон:Sfn Similarly in the German language literature, Engler's classification (1903) treated Allieae and Gilliesiae as tribes of subfamily Allioideae, within Liliaceae.Шаблон:Sfn
Modern era
In the early 20th century, doubts were expressed about the placement of the alliaceous genera within Liliaceae, based solely on the position of the ovary. Lotsy was the first taxonomist to propose separating them, and in his system he describes Alliaceae and Gilliesiaceae as new and separate families from Liliaceae (1911).Шаблон:Sfn This approach was later adopted by a number of other authorities, such as Dahlgren (1985)Шаблон:Sfn and Rahn (1998).Шаблон:Sfn
In 1926, John Hutchinson moved the tribes Allieae and Gilliesieaes from Liliaceae to the Amaryllidaceae,Шаблон:Sfn although this was not universally adopted. Thus, Allieae were variously treated as either Liliaceae, Amaryllidaceae, or Alliaceae. Further examination of the heterogeneity of the Liliaceae by Huber (1969)Шаблон:Sfn supported the removal of these two tribes, into Alliaceae and this family was treated as an independent entity from then onwards with the exception of CronquistШаблон:SfnШаблон:Sfn who reverted to a very broad concept of Liliaceae.Шаблон:Sfn
In 1985, Dahlgren, Clifford, and Yeo continuing the work of Huber, but with a more cladistic approach,Шаблон:Sfn defined the Alliaceae to include all of the genera that are now included in Allioideae (30 genera, 720 species), plus Agapanthus and a group of genera that are now placed in Themidaceae, or its equivalent, the subfamily Brodiaeoideae of Asparagaceae.Шаблон:Sfn They divided Alliaceae into three subfamilies: Agapanthoideae,Шаблон:Sfn Allioideae,Шаблон:Sfn and Gilliesioideae.Шаблон:Sfn Agapanthoideae consisted of two genera (Agapanthus and Tulbaghia). Allioideae contained two tribes, Brodiaeeae (ten genera) and a broadly defined Allieae, which they considered distinct enough to alternatively consider as subfamilies in their own right. Gilliesioideae was composed of about half of the genera now placed in Gilliesieae, the rest being assigned to Allieae.
Phylogenetic analyses
In 1996, a molecular phylogenetic study of the rbcL gene showed that Agapanthus was misplaced in Alliaceae, and the authors excluded it from the family.Шаблон:Sfn They also raised Brodiaeeae to family rank as Themidaceae. They reduced the tribe Allieae to two genera, Allium and Milula, and transferred the rest of Allieae to Gilliesieae. This is the circumscription which the Angiosperm Phylogeny Group accepted in the APG classification of 1998 and which later became known as Alliaceae sensu stricto.
In the APG II system of 2003, Alliaceae could be recognized sensu stricto or sensu lato, as mentioned above. Soon after the publication of APG II, the ICBN conserved the name Amaryllidaceae for the family that had been called Alliaceae sensu lato in APG II.
When the APG III system was published in 2009, the alternative circumscriptions were discontinued and Alliaceae was no longer recognized. Alliaceae sensu stricto became the subfamily Allioideae of Amaryllidaceae sensu lato.Шаблон:Sfn Some botanists have not strictly followed the Angiosperm Phylogeny Group and have recognized the smaller version of Alliaceae at family rank.[1][2] Successive revisions of the Angiosperm Phylogeny Group (APG) classification have changed the circumscription of the family. In the 1998 version, Alliaceae were a distinct family; in the 2003 version, combining the Alliaceae with the Agapanthaceae and the Amaryllidaceae sensu stricto was recommended but optional; in the 2009 version, only the broad circumscription of the Amaryllidaceae is allowed, with the Alliaceae reduced to a subfamily, Allioideae.Шаблон:Sfn
Quite a few of the plants that were once included in family Alliaceae have been assigned to the subfamily Brodiaeoideae (rather than the subfamily Allioideae).Шаблон:Sfn
The largest genera are Allium (260–690 species), Nothoscordum (25), and Tulbaghia (22).[3] Some of the generic limits are not clear. Ipheion, Nothoscordum, and possibly others are not monophyletic.[4]
Subdivision
Allioideae is divided into four tribes: Allieae, Tulbaghieae, Gilliesieae and Leucocoryneae.Шаблон:Sfn The first three correspond to the three subfamilies under the older family Alliaceae (Alliodiae, Tulbaghioideae and Gilliesioideae). Leucocoryneae was added in 2014 by dividing Gilliesieae into two separate tribes, corresponding to the original tribes within Gilliesioideae, elevating Iphiae nom. nud. to tribe Leucocoryneae.Шаблон:Sfn
Allieae contains only one genus Allium (Milula is merged with Allium in the latest systems). Tulbaghieae contains two genera, Tulbaghia and Prototulbaghia. Gilliesieae and Leucocoryneae contain the remaining fifteen genera. Allieae is sister to a clade composed of Tulbaghieae and Gilliesieae.[5]
Allieae
It is characterised by simple or prolific bulbs, sometimes with lateral rhizomes. Leaf sheaths are long, tepals are free and the corona is absent. Spathe is formed from 2–5 bracts. The style is positioned apical relative to the ovary. The ovary usually has two, four or numerous ovules per locule in two longitudinal rows. It has one genus, Allium, and over 500 species. It is distributed over all the Northern hemisphere. Шаблон:Sfn
Gilliesieae
Characterised by simple or prolific bulbs, sometimes with lateral rhizomes. Leaf sheaths long, tepals more or less fused and corona absent. Spathe formed from 1–2 bracts. Style more or less gynobasic. Ovary usually has two ovules per locule, side by side. Floral symmetry zygomorphic, septal nectaries absent. Nine genera native to South America.Шаблон:Sfn
Leucocoryneae
Characterised by simple or prolific bulbs, sometimes with lateral rhizomes. Leaf sheaths long, tepals more or less fused and corona absent. Spathe formed from 1–2 bracts. Style more or less gynobasic. Ovary usually has two ovules per locule, side by side. Floral symmetry actinomorphic, septal nectaries present. Six genera and 42 species, and endemic to South America with the exception of two species of Nothoscordum.Шаблон:Sfn
Tulbaghieae
Characterised by corm-shaped bulb or rhizome. Leaf sheaths short. Flowers possess a corona, pseudocorona or a fleshy perigonal ring.Шаблон:Sfn Two genera and about 25 species. Endemic to South Africa.Шаблон:Sfn

Asparagaceae subfam. Brodiaeoideae). Petronymphe has been restored to Themidaceae from AnthericaceaeШаблон:Sfn (now a segregate of Agavaceae).[7] Latace Phil. is included in Nothoscordum.
Phylogeny
Distribution
Global distribution corresponds to the tribal structure, with the Allieae confined to the Northern hemisphere (North America, North Africa, Europe and Asia), Tulbaghieae to South Africa, Gilliesieae to South America, and Leucocoryneae to South America with the exception of two species of Nothoscordum (N. bivalve, N. gracile) which extend to southern North America.Шаблон:Sfn Thus, fourteen of the total of 18 genera are endemic to temperate South America.[3]Шаблон:Sfn
Uses
Some of the species of Allium are important food plants for example onions (Allium cepa), chives (A. schoenoprasum), garlic (A. sativum and A. scordoprasum), and leeks (A. porrum).[1] Species of Allium, Gilliesia, Ipheion, Leucocoryne, Nothoscordum, and Tulbaghia are cultivated as ornamentals.[8]
