Burmanniaceae
Burmanniaceae is a Family (biology), family of flowering plants, consisting of 99 species of herbaceous plants in eight genera. Description These plants are annual or perennial herbs, with generally unbranched stems, some lacking leaves. Some members of this family lack chlorophyll and are mycotrophic (also called Myco-heterotrophy, myco-heterotrophic). The family tends to be saprophytic and even the autotrophic species are all endomycorrhizal and probably at least hemisaprophytic. The family occurs worldwide, with a mostly tropic to subtropical distribution. A number of species are threatened. Taxonomy John Lindley described the family as Burmanniae, with the single genus ''Burmannia'', in 1830. In 1998 the APG I system placed Burmanniaceae as one of five families in the order (biology), order Dioscoreales, within the monocot clade. The APG II system of 2003, as a result of an extensive study by Caddick and colleagues (2002), using an analysis of three genes, RuBisCO, ''rbc'' ...

Dioscoreales
The Dioscoreales are an order of monocotyledonous flowering plants in modern classification systems, such as the Angiosperm Phylogeny Group and the Angiosperm Phylogeny Web. Within the monocots Dioscoreales are grouped in the lilioid monocots where they are in a sister group relationship with the Pandanales. The Dioscoreales must contain the family Dioscoreaceae which includes the yam ('' Dioscorea'') which is an important food source in many regions. Older systems tended to place all lilioid monocots with reticulate veined leaves (such as Smilacaceae and Stemonaceae together with Dioscoraceae) in Dioscoreales. As currently circumscribed by phylogenetic analysis using combined morphology and molecular methods, Dioscreales contains many reticulate veined vines in Dioscoraceae, it also includes the myco-heterotrophic Burmanniaceae and the autotrophic Nartheciaceae. The order consists of three families, 22 genera and about 850 species. Description Dioscoreales are vines or her ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thismiaceae
Thismiaceae is a family of flowering plants whose status is currently uncertain. The Angiosperm Phylogeny Group classifications (APG II, APG III , and APG IV) merge Thismiaceae into Burmanniaceae, noting that some studies have suggested that Thismiaceae, Burmanniaceae and Taccaceae should be separate families, whereas others support their merger. The family has been recognized by some authors (like J. Hutchinson, Chase ''et al.'' 1995, 2000; Caddick ''et al.'' 2000; Neyland 2002; Thiele & Jordan 2002, Merckx ''et al.'' 2006 and Woodward ''et al.'' 2007). Others have supported the APG position of merging the family into Burmanniaceae, sometimes as the tribe Thismieae (Maas-van de Kamer in Kubitzki systemMaas-van de Kamer, H. (1998). Burmanniaceae.

Burmannia (plant)
''Burmannia'' is a genus of flowering plants long thought of as related to orchids, although more recent studies suggest closer affinities with either the Dioscoreales or the Melanthiales. The plants are herbs, partially autotrophic (photosynthetic) but also partially parasitic on soil fungi. ''Burmannia'' is native to tropical and subtropical parts of Africa, eastern Asia, Australia, and the Western Hemisphere. Three are regarded as native to the US:Govaerts, R., Wilkin, P. & Saunders, R.M.K. (2007). World Checklist of Dioscoreales. Yams and their allies: 1-65. The Board of Trustees of the Royal Botanic Gardens, Kew. The name ''Burmannia'' is a taxonomic patronym honoring the Dutch botanist Johannes Burman Johannes Burman (26 April 1707 in Amsterdam – 20 February 1780), was a Dutch botanist and physician. Burman specialized in plants from Ceylon, Amboina and Cape Colony. The name '' Pelargonium'' was introduced by Johannes Burman. Johannes ... (1706 - 1779). Syst ...

Gymnosiphon
''Gymnosiphon'' (yellowseed) is a genus of monocotyledonous flowering plants from the yam order. Like most of the other members of the family in which the plant is placed (Burmanniaceae), ''Gymnosiphon'' is entirely myco-heterotrophic genus that does not contain chlorophyll and respectively does not perform photosynthesis. ''Gymnosiphon'' is distributed across the moist, tropical regions of Asia, America and Africa. The plant has very small size and thin stems. Leaves are rudimentary and with appearance like scales or bracts. Its flowers are white in color, pale and solitary or sometimes collected in tiny inflorescences of few depending on the species. They are also actinomorphic with three larger outer tepals and three more inner and smaller ones. Phylogenetically ''Gymnosiphon'' is placed in the clade of Burmanniaceae Burmanniaceae is a family of flowering plants, consisting of 99 species of herbaceous plants in eight genera.
