Psychopsiella
''Psychopsiella'' is a monotypic genus in the orchid family found only in the state of Rio de Janeiro in Brazil and near Caracas in Venezuela. It grows as an epiphyte in evergreen montane forests at elevations of . Chase, Mark W. "Psychopsis limminghei." ''Curtis's Botanical Magazine.'' Feb. 2005: 23-25. ''Jstor.'' Web. 4 Mar. 2020. Description ''Psychopsiella limminghei'' is an epiphytic herb with a short rhizome, usually of a length within between pseudobulbs. It has a creeping habit of growth, with both pseudobulbs and leaves pressed against the substrate. Its pseudobulbs, long and wide, are elliptic, flattened, and irregularly ribbed, often with one or two bracts. Each pseudobulb carries one ovate-elliptic leaf long and wide. Leaves are pale green, splotched with maroon, with a rough surface and asymmetric base. The inflorescence emerges erect from the base of the pseudobulb, usually carrying one flower at a time; up to four additional flowers can be produced su ...

Psychopsis
''Psychopsis'' is a genus of four known species of orchids native to northern South America, Central America and Trinidad. The genus name is abbreviated ''Pyp.'' in the horticultural trade.Alphabetical List of Standard Abbreviations for Natural and Hybrid Generic Names, Royal Horticultural Society, 2017. https://www.rhs.org.uk/plants/pdfs/plant-registration-forms/orchid-name-abbreviations-list.pdf Description ''Psychopsis'' are epiphytic orchids with laterally crushed cylindrical pseudobulbs from which two fleshy coriaceous leaves appear apically, in their center two floral wands emerge with large golden yellow flowers with purple spots on bands in sepals and on the lip whose edges are forming folds. ''Psychopsis'' very often grows on the trunks and branches of trees. The flowers look like large butterflies with brightly colored bodies (the lip, a modified petal), very long antennae-like petals, and outspread wing-like dappled yellow and brown sepals. The butterfly orchid is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Oncidioid 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'' * '' Centro ...

Author Citation (botany)
In botanical nomenclature, author citation is the way of citing the person or group of people who validly published a botanical name, i.e. who first published the name while fulfilling the formal requirements as specified by the '' International Code of Nomenclature for algae, fungi, and plants'' (''ICN''). In cases where a species is no longer in its original generic placement (i.e. a new combination of genus and specific epithet), both the authority for the original genus placement and that for the new combination are given (the former in parentheses). In botany, it is customary (though not obligatory) to abbreviate author names according to a recognised list of standard abbreviations. There are differences between the botanical code and the normal practice in zoology. In zoology, the publication year is given following the author names and the authorship of a new combination is normally omitted. A small number of more specialized practices also vary between the recommendation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...

Orchids Of Brazil
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 v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centris
The genus ''Centris'' contains circa 250 species of large apid bees occurring in the Neotropical and Nearctic realms, from Kansas to Argentina. Most females of these bees possess adaptations for carrying floral oils rather than (or in addition to) pollen or nectar. They mainly visit plants of the family Malpighiaceae to collect oil, but also visit others such as Plantaginaceae, Calceolariaceae, and Krameriaceae. Recent studies have shown they are sister to the corbiculate bees, the most well-known and economically important group of bees They are large (up to 3 cm), fast-flying bees, distinguished from the closely related genus '' Epicharis'' by the absence of long, whip-like setae that project backwards from just behind the eyes. They are commonly encountered bees in American deserts, and are active at very high ambient temperatures when many other species are in hiding. They can often be seen in large numbers on desert-willow (''Chilopsis'') and palo verde (''Parkinso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oncidium
''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 publication ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
England
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century. The English language, the Anglican Church, and Engli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pollinium
A pollinium (plural pollinia) is a coherent mass of pollen grains in a plant that are the product of only one anther, but are transferred, during pollination, as a single unit. This is regularly seen in plants such as orchids and many species of milkweeds ( Asclepiadoideae). Usage of the term differs: in some orchids two masses of pollen are well attached to one another, but in other orchids there are two halves (with two separate viscidia) each of which is sometimes referred to as a pollinium. Most orchids have waxy pollinia. These are connected to one or two elongate stipes, which in turn are attached to a sticky viscidium, a disc-shaped structure that sticks to a visiting insect. Some orchid genera have mealy pollinia. These are tapering into a caudicle (stalk), attached to the viscidium. They extend into the middle section of the column. The pollinarium is a collective term that means either (1) the complete set of pollinia from all the anthers of a flower, as in Asclepiadoidea ...

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] |
Petals
Petals are modified leaves that surround the reproductive parts of flowers. They are often brightly colored or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually accompanied by another set of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include genera such as ''Aloe'' and ''Tulipa''. Conversely, genera such as ''Rosa'' and '' Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly colored tepals. Since they include Liliales, an alternative ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
