Colchicaceae
Template:Short description Template:Automatic taxobox
Colchicaceae is a family of flowering plants that includes 15 genera with a total of about 285 known species according to Christenhusz and Byng in 2016.<ref name="Christenhusz-Byng2016">Template:Cite journal</ref>
DescriptionEdit
The family is characterized by the presence of colchicine.Template:Sfn
TaxonomyEdit
The APG III system, of 2009 (unchanged from the APG systems, of 1998 and 2003), recognizes this family and places it in the order Liliales, in the clade monocots.<ref name=APGIII2009/> It is a group of herbaceous perennials with rhizomes or corms.
The Dahlgren system and the Thorne system (1992) also recognized this family, and placed it in order Liliales in superorder Lilianae in subclass Liliidae (monocotyledons) of class Magnoliopsida (angiosperms).
GeneraEdit
The phylogenetic classification of Vinnersten & Manning circumscribes the family as follows:Template:Sfn
- tribe Burchardieae
- Burchardia R.Br.
- tribe Uvularieae
- tribe Tripladenieae
- Kuntheria Conran & Clifford
- Schelhammera R.Br.
- Tripladenia D.Don
- tribe Iphigenieae
- Camptorrhiza E.Phillips
- Iphigenia Kunth
- tribe Anguillarieae
- tribe Colchiceae
- Colchicum L. (including Androcymbium Willd., Bulbocodium L. and Merendera Ramond)
- Gloriosa L. (including Littonia Hook.)
- Hexacyrtis Dinter
- Ornithoglossum Salisb.
- Sandersonia Hook.
The genus Petermannia F.Muell. is excluded from this family and placed in its own family Petermanniaceae, Liliales. The former controversy regarding the inclusion of Androcymbium in Colchicum has now been resolved in favor of the 2007 classification of Manning et al.<ref>Template:Cite journal</ref> who included Androcymbium in Colchicum. This is supported by molecular phylogenetic studies with dense species sampling (i.e. 41 species previously placed in Androcymbium and 96 species of Colchicum) that showed that the type species of Androcymbium, A. melanthioides (Colchicum melanthioides), is more closely related to species of Colchicum than it is to many species traditionally placed in Androcymbium.<ref>Template:Cite journal</ref><ref>Template:Cite journal</ref>
Subsequently, Nguyen et al.(2013) proposed reclassifying the family on the basis of subfamilies:Template:Sfn
- Subfamily Uvularioideae (distribution: Eastern Asia and North America)
- Tribe Uvularieae (Disporum, Uvularia)
- Subfamily Wurmbeoideae (distribution: Australia, Africa, Europe, central and tropical Asia)
- Tribe Burchardieae (Burchardia)
- Tribe Tripladenieae (Tripladenia, Schelhammera, Kuntheria)
- Tribe Iphigenieae (Iphigenia, Camptorrhiza)
- Tribe Angullarieae (Wurmbea, Onixotis, Neodregea, Baeometra)
- Tribe Colchiceae (Gloriosa (including Littonia), Colchicum (including Merendera, Bulbocodium, and probably Androcymbium), Hexacyrtis, Ornithoglossum, Sandersonia
