Cyrtochiloides
''Cyrtochiloides'', a genus of orchids described in 2001 by Norris H. Williams and Mark W. Chase, is designed to provide a small group of Neotropical epiphytes, previously included under a broad concept of Oncidium Sw., with a new, more accurate identity based on DNA. ''Cyrtochiloides'' is akin to the mainly South American Cyrtochilum Kunth, a genus described in 1815. After having found its species scattered in Oncidium and several other genera, recently Cyrtochilum received notable acceptance by botanists, primarily based on the molecular discoveries made by Williams and Chase, as well as morphological analyses carried out by Stig Dalström. DNA samples illustrate that Oncidium ochmatochilum Rchb.f. and several other species have only a diluted connection with the core of the Oncidium species. This new genus forms part of a well-supported clade including Otoglossum (Schltr.) Garay & Dunsterville, Cyrtochilum, the Andean group of Caucaea Schltr. (also previously retained und ...

Oncidiinae Genera
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 lip to the 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'' * ''Brassia'' * '' Caluera'' * '' Capanemia'' * '' Caucaea'' * '' Centroglossa'' ...

Orchid
Orchids are plants that belong to the family Orchidaceae (), a diverse and widespread group of flowering plants with blooms that are often colourful and fragrant. Orchids are cosmopolitan plants that are found in almost every habitat on Earth except glaciers. The world's richest diversity of orchid genera and species is in the tropics. Orchidaceae is one of the two largest families of flowering plants, the other being the Asteraceae. It contains about 28,000 currently accepted species in 702 genera. The Orchidaceae family encompasses about 6–11% of all species of seed plants. The largest genera are '' Bulbophyllum'' (2,000 species), '' Epidendrum'' (1,500 species), '' Dendrobium'' (1,400 species) and '' Pleurothallis'' (1,000 species). It also includes '' Vanilla'' (the genus of the vanilla plant), the type genus '' Orchis'', and many commonly cultivated plants such as '' Phalaenopsis'' and '' Cattleya''. Moreover, since the introduction of tropical species into cu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epiphyte
An epiphyte is a plant or plant-like organism that grows on the surface of another plant and derives its moisture and nutrients from the air, rain, water (in marine environments) or from debris accumulating around it. The plants on which epiphytes grow are called phorophytes. Epiphytes take part in nutrient cycles and add to both the diversity and biomass of the ecosystem in which they occur, like any other organism. In some cases, a rainforest tree's epiphytes may total "several tonnes" (several long tons). They are an important source of food for many species. Typically, the older parts of a plant will have more epiphytes growing on them. Epiphytes differ from parasites in that they grow on other plants for physical support and do not necessarily affect the host negatively. An organism that grows on another organism that is not a plant may be called an epibiont. Epiphytes are usually found in the temperate zone (e.g., many mosses, liverworts, lichens, and algae) or in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |

Otoglossum
''Otoglossum'' is a genus of flowering plants from the orchid family, Orchidaceae, native to South America and Central America.Jenny, R. (2010). ''Otoglossum'', una revisión taxonómica. Orquideología 27: 63-95. Description They are plants of ovoid pseudobulbs spaced in long, along a creeping or ascending upward rhizomes, with thick and tanned leathery leaves. The inflorescence is axillary, racemosa, erect, starting from the sheaths of the pseudobulbs, racemous, erect, with many rather large and wavy or curly, rounded flowers. The petals and sepals have similar shapes and sizes, with very frizzy, oval, large margins, somewhat concave. The lip is inserted at the base of the column. The spine is short, sometimes with dorsal calluses. The spine is short, apodes, sometimes with dorsal calluses before the stigmatic cavity, small wings or auricles, and terminal anther somewhat inserted under the terminal margins of the spine.
