Coeliopsidinae
Coeliopsidinae is an orchid subtribe in the tribe Cymbidieae. The three members of this subtribe have traditionally been lumped in with Stanhopeinae, but obvious morphological traits and new molecular analysis by Whitten et al. in 2000 confirmed the group reclassified by Szlachetko (1995). These genera have smooth, unribbed, ovoid pseudobulbs with 3-4 large and thin plicate leaves. The inflorescences are thick and bear globose flowers with thick, fleshy sepals and petals, presence of a column foot and mentum. Roots have prominent root hairs. Most distinct is the viscidia that are button-shaped and sclerified with short stipes. The three genera all have elongated ''Maxillaria''-type dust seeds and not ''Stanhopea''-type balloon seeds. Like Stanhopeinae the members of this group are pollinated by male euglossine bees. The sticky viscidia of this group are adapted to attachment on the smooth surface of the scutum The ''scutum'' (; plural ''scuta'') was a type of shield used ...

Stanhopeinae
Stanhopeinae is a subtribe of plants in the tribe Cymbidieae. The subtribe in the strict sense, have viscidia and stipes that are thin and strap-like, they are adapted for attachment to edge of the bee's scutellum or to a leg. Pseudobulbs are usually ribbed/four-angled or flattened. Leaves are generally thicker than Coeliopsidinae. Roots are smooth, without prominent root hairs. The column foot is lacking or not distinct. Unpollinated flowers quickly abscise and fall from the inflorescence, unlike members of Coeliopsidinae which include ''Coeliopsis'', '' Lycomormium'', and '' Peristeria''. Stanhopeinae and Coeliopsidinae are now considered closely related sister subtribes. Within Stanhopeinae the members can be further grouped in six clades based on morphological traits and molecular analysis. *''Braemia'' Clade: '' Braemia'' *''Gongora'' Clade: ''Cirrhaea'' & '' Gongora'' *''Acineta'' Clade: ''Acineta'', '' Lacaena'', ''Lueddemannia'' & ''Vasqueziella'' *''Polycycnis'' Clade: ...

Peristeria (plant)
''Peristeria'' is a genus of plants of the family OrchidaceaePridgeon, A.M., Cribb, P.J., Chase, M.C. & Rasmussen, F.N. (2009). Epidendroideae (Part two). Genera Orchidacearum 5: 1-585. Oxford University Press, New York, Oxford. commonly called dove orchid or Holy Ghost orchid. In line with the common name, the genus' name is from the Greek word ''peristerion'' meaning "from dove". According to the Royal Horticultural Society, Per is the official orchid abbreviation for this genus. In nature, it is found across much of South America as well as in Panama, Costa Rica and Trinidad. ''Peristeria elata'' is the national flower of Panama and is extremely over-collected in its native habitat. This over collection has led to its status as a species threatened with extinction delineated in Appendix I of CITES. In its native habitat, Peristeria can usually be found growing near the edge of hardwood forests. In the fall, after the trees in the hardwood forest lose their leaves, the plants ...

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. 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] |
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.

Sepal
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively the sepals are called the calyx (plural calyces), the outermost whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. ''Calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet', and the words have been used interchangeably in botanical Latin. After flowering, most plants have no more use for the calyx which withers or becomes vestigial. Some plants retain a thorny calyx, either dried or live, as ...

Petal
Petals are modified Leaf, leaves that surround the reproductive parts of flowers. They are often advertising coloration, 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 Genus, genera such as ''Aloe'' and ''Tulipa''. Conversely, genera such as ''Rose, 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. Sinc ...

Viscidium
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 Asclepiadoideae ...

Euglossini
The tribe (biology), tribe Euglossini, in the subfamily Apinae, commonly known as orchid bees or euglossine bees, are the only group of Pollen basket, corbiculate bees whose non-parasitic members do not all possess Eusociality, eusocial behavior. Description Most of the tribe's species are solitary, though a few are communal, or exhibit simple forms of eusociality. There are about 200 described species, distributed in five genera: ''Euglossa'', ''Eulaema'', ''Eufriesea'', ''Exaerete'' and the monotypic ''Aglae''. All exclusively occur in South or Central America (though one species, ''Euglossa dilemma'', has become established in the United States). The genera ''Exaerete'' and ''Aglae'' are Kleptoparasite, kleptoparasites in the nests of other orchid bees. All except ''Eulaema'' are characterized by brilliant metallic coloration, primarily green, gold, and blue. Females gather pollen and nectar as food from a variety of plants, and resins, mud and other materials for nest build ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
