Description

Small perennial or annual mycorrhizal herbs that are achlorophyllous (lacking chlorophyll) and mycotrophic or less often autotrophic.Lua error in package.lua at line 80: module 'Module:Footnotes/anchor_id_list' not found.

Systematics and taxonomy

Carl Friedrich Philipp von Martius listed the ordo (that is, family)[b] Burmanniaceae in 1835 and consequently has been cited as an authority, although he acknowledged earlier descriptions by Carl Ludwig Blume (1827) and John Lindley (1830).Lua error in package.lua at line 80: module 'Module:Footnotes/anchor_id_list' not found.

In 1927 Heintze elevated the Burmanniaceae family to the rank of the Burmanniales order.Lua error in package.lua at line 80: module 'Module:Footnotes/anchor_id_list' not found. Subsequent authors have followed this, including Lawrence 1951,Lua error in package.lua at line 80: module 'Module:Footnotes/anchor_id_list' not found. Hutchinson 1973,Lua error in package.lua at line 80: module 'Module:Footnotes/anchor_id_list' not found. Dahlgren 1980Lua error in package.lua at line 80: module 'Module:Footnotes/anchor_id_list' not found.) and Thorne 1992.Lua error in package.lua at line 80: module 'Module:Footnotes/anchor_id_list' not found. Johri et al. treat the 17 families of order Liliiflorae as distributed over 5 suborders, including Burmanniineae Engl.. The latter suborder was then considered to contain two families, Burmanniaceae and Corsiaceae.Lua error in package.lua at line 80: module 'Module:Footnotes/anchor_id_list' not found. As circumscribed by Dahlgren (sensu Dahlgren) it was one of five orders belonging to the superorder Liliiflorae and was composed of three families, Burmanniaceae (the type family), Thismiaceae, and Corsiaceae.Lua error in package.lua at line 80: module 'Module:Footnotes/anchor_id_list' not found. Later, Burmanniales was included by Takhtajan in the 2009 revision of his system with the same family structure, as an order of superorder Lilianae (as the Liliiflorae were renamed).Lua error in package.lua at line 80: module 'Module:Footnotes/anchor_id_list' not found.

Phylogeny

Historically the Burmanniales were considered the closest to the orchids, being epigynous with small seeds, although this was not supported when subjected to cladistic analysis,Lua error in package.lua at line 80: module 'Module:Footnotes/anchor_id_list' not found.Lua error in package.lua at line 80: module 'Module:Footnotes/anchor_id_list' not found. suggesting these characteristics were actually convergent.Lua error in package.lua at line 80: module 'Module:Footnotes/anchor_id_list' not found. Phylogenetic analysis showed that Burmanniales was actually polyphyletic,Lua error in package.lua at line 80: module 'Module:Footnotes/anchor_id_list' not found.Lua error in package.lua at line 80: module 'Module:Footnotes/anchor_id_list' not found. resulting in a redistribution of the families between the Liliales and Dioscoreales orders. With the type family Burmanniaceae placed in Dioscoreales (together with Thismiaceae), the Burmanniales order became redundant and was discontinued.

Etymology

The name is derived by typification from the type genus Burmannia, named after the Dutch botanist Johannes Burman (1707–1779),Lua error in package.lua at line 80: module 'Module:Footnotes/anchor_id_list' not found. followed by the suffix -iales, to indicate the rank of order.
