Alliaceae

TaxonomyAlliaceae, Allioideae, is a Subfamily in Amaryllidaceae. Alliaceae have a long history in classifications.
Linnaeus placed Allium in a grouping Hexandria monogynia.
In 1763, Adanson placed Allium in Liliaceae.
De Jussieu placed Allium in the Order Asphodeles.
Subsequently, de Candolle reverted the family name back to Liliaceae.
The 'Alliaceae' have been treated as Allieae within the Liliaceae (or Aspholecaceae, a partial synonym) family by most authorities since.
In 1830, Lindley considered Alliaceae to be part of the Asphodeleae tribe, closely related Gilliesieae. Later he absorbed Asphodeleae into this family, in a suborder of Scilleae.
In 1883 Bentham and Hooker Allieae had become one of twenty tribes within Liliaceae, including Gilliesieae as one of its four subtribes.
In 1903 Engler classified Allieae and Gilliesiae as tribes of the subfamily Allioideae, within Liliaceae.
In 1911 Lotsy described Alliaceae and Gilliesiaceae as families separate from Liliaceae (1911). This approach was later adopted by a number of other authorities, such as Dahlgren (1985) and Rahn (1998) copied this classification
In 1926 John Hutchinson moved the Allieae and Gilliesieae tribes from Liliaceae to the Amaryllidaceae.
Thus Allieae were variously treated as either Liliaceae, Amaryllidaceae or Alliaceae.
Cronquist reverted Alliaceae to a very broad concept of Liliaceae.
In 1985, Dahlgren, Clifford, and Ye defined the Alliaceae to include all genera in Allioideae (30 genera, 720 species), plus Agapanthus and a group of genera that are now placed in Themidaceae, dividing Alliaceae into three subfamilies Agapanthoideae, Allioideae, and Gilliesioideae. Agapanthoideae consisted of Agapanthus and Tulbaghia. Allioideae contained two tribes, Brodiaeeae (ten genera) and a broadly defined Allieae, including Gilliesioideae.
In 1996 molecular phylogenetic studies started.
Fay showed that Agapanthus was misplaced in Alliaceae, and the authors excluded it from the family and that Brodiaeeae was more of a family, as Themidaceae. Fay reduced Allieae to two genera, Allium and Milula, and transferred the rest of Allieae to Gilliesieae.
The Apg1 classification of 1998 defined Alliaceae as fay showed.
In the Apg2 system of 2003, Alliaceae could be boadly or strictly defined. Soon after the publication of Apg2 Alliaceae broadly defined was given the name Amaryllidaceae.
When the Apg3 system of 2009, Alliaceae strictly defined became the subfamily Allioideae of Amaryllidaceae. Amaryllidaceae bwcaem defines as consisting of 3 Subfamilies, Agapanthoideae, Allioideaeand Amarylloideae. The Family Themidaceae, once part of Aliiaceae, was placed as the subfamily Brodiaeoideae in Asparagaceae.
