Oncidiinae
The Oncidiinae is a subtribe within the Orchidaceae that consists of a number of genera that are closely related. This subtribe consists of about 70 genera with over 1000 species, with ''Oncidium'' as its largest genus. These genera consist of a single floral type based on the angle of the attachment of the Labellum (botany), lip to the Column (botany), column, reflecting pollinator preferences. This has however led to several unreliable results and polyphyletic taxa within ''Oncidium''. These were transferred to ''Gomesa'' and a new genus ''Nohawilliamsia'', has been described for ''Oncidium orthostates'' Most species have well-developed pseudobulbs and conduplicate leaves. It is possible to form hybrids in some instances between multiple genera within the Oncidiinae. These hybrids are often colloquially referred to as "intergenerics." Genera Genera recognized in Chase et al.'s 2015 classification of Orchidaceae: * ''Aspasia (plant), Aspasia'' * ''Brassia'' * ''Caluera'' * ...

Oncidium
''Oncidium'', abbreviated as Onc. in the horticultural trade, is a genus that, , contains about 340 species of orchids from the subtribe Oncidiinae of the orchid family Orchidaceae. It is distributed across tropical and subtropical America from Mexico, Central America and the West Indies to northern Argentina, with one species (''O. ensatum'') extending into Florida. Common names for plants in this genus include dancing-lady orchid and golden shower orchid. A 2008 molecular phylogenetic study labeled the ''Oncidium'' alliance "grossly polyphyletic." In the same year, the American Orchid Society labeled the genus a "dumping ground".Lindleyana : The scientific journal of the American Orchid Society. December 2008 Pg 20 A consensus announced in April 2013 resulted in major taxonomic changes to ''Oncidium'', '' Gomesa'', '' Odontoglossum'', ''Miltonia'', and others. Much of this debate and subsequent housekeeping was initiated by significant research for the scientific publicat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
