Baptistonia
''Oncidium'', abbreviated as Onc. in the horticultural trade, is a genus that contains about 330 species of orchids from the subtribe Oncidiinae of the orchid family (Orchidaceae). As presently conceived (May 2014), it is distributed across much of South America, Central America, Mexico and the West Indies, with one species ''(O. ensatum)'' extending into Florida. Common names for plants in this genus include dancing-lady orchid and golden shower orchid. In 2008, Oxfords Annals of Botany labeled the ''Oncidium'' alliance "grossly polyphyletic." The American Orchid Society labeled this genus a "dumping ground."Lindleyana : The scientific journal of the American Orchid Society. December 2008 Pg 20 After DNA testing and much debate, a consensus was announced (April 2013) resulting 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 publicati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miltonia
''Miltonia'', abbreviated Milt. in the horticultural trade, is an orchid genus comprising twelve epiphyte species and eight natural hybrids. The miltonias are exclusively inhabitants of Brazil, except for one species whose range extends from Brazil into the northeast of Argentina and the east of Paraguay. The genus of ''Miltonia'' was established by John Lindley in 1837, when he described its type species, ''Miltonia spectabilis''. Formerly many more species were attributed to ''Miltonia'', however, beginning in 1978, the miltonias from Central America and from cooler areas of northwest South America have been moved to other genera, including Miltoniopsis and Oncidium, and these changes are still in the process of being accepted by the horticultural trade. ''Miltonia'' species have large and long lasting flowers, often in multifloral inflorescences. This fact, allied to being species that are easy to grow and to identify, make them a favorite of orchid collectors all over the wo ...

Odontoglossum
''Odontoglossum'', first named in 1816 by Karl Sigismund Kunth, is a genus of about 100 orchids. The scientific name is derived from the Greek words ''odon'' (tooth) and ''glossa'' (tongue), referring to the two tooth-like calluses on the base of the lip. This genus of cool to cold growing orchids is to be found on open spots in the humid cloud forest at higher elevations from Central- and West South America to Guyana, with most species around the northern Andes. The abbreviation for this genus is ''Odm''. in the horticultural trade. Most are sympodial epiphytes, or rarely terrestrials. The pseudobulbs are compact with leaf-like bracts at the base. They give one to three apical leaves. An arching (and sometimes erect) inflorescence grows from its base. The ruffled sepals and petals of these spectacular flowers are spreading. The lip is rather complex, entire or with three lobes. It stands erect or parallel to the long column. The high altitude species show long infloresc ...

Gomesa
''Gomesa'' is a genus of flowering plants from the orchid family, Orchidaceae. It contains about 80–100 species, all native to South America. The genus is abbreviated as ''Gom''. Royal Horticultural Society, 2017 Species This genus contains many species that were previously assigned to ''''. Species include: # '' Gomesa adamantina'' (Marçal & Cath.)

Orchids
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. Along with the Asteraceae, they are one of the two largest families of flowering plants. The Orchidaceae have about 28,000 currently accepted species, distributed in about 763 genera. (See ''External links'' below). The determination of which family is larger is still under debate, because verified data on the members of such enormous families are continually in flux. Regardless, the number of orchid species is nearly equal to the number of bony fishes, more than twice the number of bird species, and about four times the number of mammal species. The 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Raceme
A raceme ( or ) or racemoid is an unbranched, indeterminate type of inflorescence bearing flowers having short floral stalks along the shoots that bear the flowers. The oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. Examples of racemes occur on mustard (genus ''Brassica'') and radish (genus ''Raphanus'') plants. Definition A ''raceme'' or ''racemoid'' is an unbranched, indeterminate type of inflorescence bearing pedicellate flowers (flowers having short floral stalks called ''pedicels'') along its axis. In botany, an ''axis'' means a shoot, in this case one bearing the flowers. In indeterminate inflorescence-like racemes, the oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. A plant that flowers on a showy raceme may have this reflected in its scientific name, e.g. the species ''Cimicifuga racemosa''. A compou ...

Caribbean
The Caribbean (, ) ( es, El Caribe; french: la Caraïbe; ht, Karayib; nl, De Caraïben) is a region of the Americas that consists of the Caribbean Sea, its islands (some surrounded by the Caribbean Sea and some bordering both the Caribbean Sea and the North Atlantic Ocean) and the surrounding coasts. The region is southeast of the Gulf of Mexico and the North American mainland, east of Central America, and north of South America. Situated largely on the Caribbean Plate, the region has more than 700 islands, islets, reefs and cays (see the list of Caribbean islands). Island arcs delineate the eastern and northern edges of the Caribbean Sea: The Greater Antilles and the Lucayan Archipelago on the north and the Lesser Antilles and the on the south and east (which includes the Leeward Antilles). They form the West Indies with the nearby Lucayan Archipelago (the Bahamas and Turks and Caicos Islands), which are considered to be part of the Caribbean despite not bordering the Caribbe ...

Florida
Florida is a state located in the Southeastern region of the United States. Florida is bordered to the west by the Gulf of Mexico, to the northwest by Alabama, to the north by Georgia, to the east by the Bahamas and Atlantic Ocean, and to the south by the Straits of Florida and Cuba; it is the only state that borders both the Gulf of Mexico and the Atlantic Ocean. Spanning , Florida ranks 22nd in area among the 50 states, and with a population of over 21 million, it is the third-most populous. The state capital is Tallahassee, and the most populous city is Jacksonville. The Miami metropolitan area, with a population of almost 6.2 million, is the most populous urban area in Florida and the ninth-most populous in the United States; other urban conurbations with over one million people are Tampa Bay, Orlando, and Jacksonville. Various Native American groups have inhabited Florida for at least 14,000 years. In 1513, Spanish explorer Juan Ponce de León became the first k ...

Pseudobulb
The pseudobulb is a storage organ found in many epiphytic and terrestrial sympodial orchids. It is derived from a thickening of the part of a stem between leaf nodes and may be composed of just one internode or several, termed heteroblastic and homoblastic respectively. All leaves and inflorescences usually arise from this structure. Pseudobulbs formed from a single internode produce the leaves and inflorescence from the top, while those that are formed from several internodes can possess leaves along its length.Hew, C.S., and J.W.H. Yong. 2004The Physiology of Tropical Orchids in Relation to the Industry.Singapore: World Scientific Publishing Co. pp. 13-15. The modified sheath leaves that appear at the base of a pseudobulb and often enfold all or part of it are usually dry and papery, though in some orchids the sheaths bear leaf blades and the leaves at the pseudobulb's apex are reduced to scales.Dressler, R.L. 1993.

Leaf
A leaf ( : leaves) is any of the principal appendages of a vascular plant stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. Most leaves are flattened and have distinct upper (adaxial) and lower ( abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due to the presence of a compound called chlorophyll that is essential for photosynthesis as it absorbs light ...

Labellum (botany)
In botany, the labellum (or lip) is the part of the flower of an orchid or '' Canna'', or other less-known genera, that serves to attract insects, which pollinate the flower, and acts as a landing platform for them. ''Labellum'' (plural: ''labella'') is the Latin diminutive of ''labrum'', meaning lip. The labellum is a modified petal and can be distinguished from the other petals and from the sepals by its large size and its often irregular shape. It is not unusual for the other two petals of an orchid flower to look like the sepals, so that the labellum stands out as distinct. Bailey, L. H. ''Gentes Herbarum: Canna x orchiodes''. (Ithaca), 1 (3): 120 (1923); Khoshoo, T. N. & Guha, I. ''Origin and Evolution of Cultivated Cannas.'' Vikas Publishing House. In orchids, the labellum is the modified median petal that sits opposite from the fertile anther and usually highly modified from the other perianth segments. It is often united with the column and can be hinged or movable, fac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lithophyte
Lithophytes are plants that grow in or on rocks. They can be classified as either epilithic (or epipetric) or endolithic; epilithic lithophytes grow on the surfaces of rocks, while endolithic lithophytes grow in the crevices of rocks (and are also referred to as chasmophytes). Lithophytes can also be classified as being either obligate or facultative. Obligate lithophytes grow solely on rocks, while facultative lithophytes will grow partially on a rock and on another substrate simultaneously. Nutrients Lithophytes that grow on land feed off nutrients from rain water and nearby decaying plants, including their own dead tissue. It is easier for Chasmophytes to acquire nutrients because they grow in fissures in rocks where soil or organic matter has accumulated. For most Lithophytes, nitrogen is only available through interactions with the atmosphere. The most readily available form of nitrogen in the atmosphere is the gaseous state of ammonia (NH3). Lithophytes consume atmospheric a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
