Cypripedioideae
Cypripedioideae is a subfamily of orchids commonly known as lady's slipper orchids, lady slipper orchids or slipper orchids. Cypripedioideae includes the genera ''Cypripedium, Mexipedium, Paphiopedilum, Phragmipedium'' and ''Selenipedium''. They are characterised by the slipper-shaped pouches (modified labella) of the flowers – the pouch traps insects so they are forced to climb up past the staminode, behind which they collect or deposit pollinia, thus fertilizing the flower. There are approximately 165 species in the subfamily. Description All representatives of the Cypripedioideae are perennial, herbaceous plants. The fleshy roots sometimes possess a veil. The leaves are arranged spirally or in two rows, the shoot is slender or compressed. In the bud, the leaves are rolled and the leaf blade is plikat (folded) or the leaves are folded in the bud, smooth and leathery. There is no dividing tissue between leaf and shoot. The inflorescence of the Cypripedioideae are termi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pouch (orchids)
Cypripedioideae is a subfamily of orchids commonly known as lady's slipper orchids, lady slipper orchids or slipper orchids. Cypripedioideae includes the genera ''Cypripedium, Mexipedium, Paphiopedilum, Phragmipedium'' and ''Selenipedium''. They are characterised by the slipper-shaped pouch (orchids), pouches (modified Labellum (botany), labella) of the flowers – the pouch traps insects so they are forced to climb up past the staminode, behind which they collect or deposit pollinium, pollinia, thus fertilizing the flower. There are approximately 165 species in the subfamily. Description All representatives of the Cypripedioideae are perennial, herbaceous plants. The fleshy roots sometimes possess a veil.

Taxonomy Of The Orchid Family
The taxonomy of the Orchidaceae ( orchid family) has evolved slowly during the last 250 years, starting with Carl Linnaeus who in 1753 recognized eight genera.Carolus Linnaeus (Carl von Linné). 1753. ''Species Plantarum'', 1st edition, vol. 2, pages 939-954. Holmiae: Impensis Laurentii Salvii (Lars Salvius). (A facsimile with an introduction by William T. Stearn was published by the Ray Society in 1957). (See ''External links'' below). De Jussieu recognized the Orchidaceae as a separate family in his Genera Plantarum in 1789.Antoine Laurent de Jussieu. 1789. "ORCHIDEAE" pages 64-66. In: ''Genera plantarum: secundum ordines naturales disposita,···'' (See ''External links'' below). Olof Swartz recognized 25 genera in 1800.Olof Swartz. 1800. "Afhandling om Orchidernes Slägter och deras Systematiska indelning". ''Kongliga vetenskaps academiens nya handlingar'' 21:115-139. (See ''External links'' below).

Orchidaceae
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] |
Mexipedium
''Mexipedium'' is a monotypic genus of the Orchid family Orchidaceae, subfamily Cypripedioideae, consisting of only one species, ''Mexipedium xerophyticum''. It is also the single genus of tribe Mexipedieae and subtribe Mexipediinae. Taxonomy and discovery This species was initially described as ''Phragmipedium xerophyticum'' by Soto Arenas, Salazar & Hágsater in 1990, but transferred to its own genus by Albert & Chase in 1992, in part based on results from DNA analysis. The genus ''Mexipedium'' is listed as ''Phragmipedium'' in Appendix I of the Convention on International Trade in Endangered Species (CITES), and for other legal purposes. Allied genera include ''Cypripedium'', ''Paphiopedilum'', ''Selenipedium'' and ''Phragmipedium''. Its name is derived from the country of origin Mexico and the Latin ' (“foot”), referring to the slipper-shaped lip. The specific epithet ''xerophyticum'' is from the Greek ''ξηρός'' (''xērós'', "dry") and ''φυτόν'' (''phutón'', ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paphiopedilum
''Paphiopedilum'', often called the Venus slipper, is a genus of the lady slipper orchid subfamily ''Cypripedioideae'' of the flowering plant family Orchidaceae. The genus comprises some 80 accepted taxa including several natural hybrids. The genus is native to Southeast Asia, the Indian Subcontinent, southern China, New Guinea and the Solomon and Bismarck Islands. The type species of this genus is ''Paphiopedilum insigne''. The species and their hybrids are extensively cultivated, and are known as either paphiopedilums, or by the abbreviation paphs in horticulture. Due to their popularity, Paphiopedilums have been ruthlessly gathered and poached from the wild, making them very rare or extinct there. As soon as a new species or population is discovered, poachers will take the plants for orchid collectors who pay large sums of money. Habitat destruction is an additional factor contributing to their rarity. Description ''Paphiopedilum'' species naturally occur among humus la ...

Selenipedium
''Selenipedium'' is a genus of the Orchid family (''Orchidaceae'') (Subfamily ''Cypripedioideae''). The genus has been given its own tribe, Selenipedieae, and subtribe, Selenipediinae.Pridgeon, A.M.; Cribb, P.J.; Chase, M.W. & F. N. Rasmussen (1999): Genera Orchidacearum Vol.1, Oxford U. Press. It is abbreviated Sel in trade journals. The name of the genus is derived from the Greek ''selen'', which means "moon", and ''pedium'', which means "slipper" (referring to the pouch). The seed capsules of these Central and South American lady's slipper orchids were formerly used as vanilla substitutes, but selenipediums are now rarely cultivated. Partly this is because of the difficulty of doing so, but is probably also due to the relatively small size of the Selenipedium's flower. The wild flower's Amazonian habitat is also under threat, so extinction is a risk for all species of Selenipedium. Accepted species include: * ''Selenipedium aequinoctiale'' Garay — Ecuador * ''Selenipediu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phragmipedium
''Phragmipedium'' is a genus of the Orchid family (Orchidaceae) (Subfamily Cypripedioideae) and the only genus comprised in the tribe Phragmipedieae and subtribe Phragmipediinae. The name of the genus is derived from the Greek ''phragma'', which means "division", and ''pedium'', which means "slipper" (referring to the pouch). It is abbreviated 'Phrag' in trade journals. About 20 species of these lady's slipper orchids are known from SW Mexico, Central and tropical South America. All ''Phragmipedium'' species are listed under Appendix I of the Convention on International Trade in Endangered Species (CITES), meaning that commercial international trade in wild-sourced specimens is prohibited, while non-commercial trade is regulated. Taxonomy The genus ''Phragmipedium '' is divided into several sections : * Phragmipedium : ''P. caudatum, P. exstaminodium, P. lindenii'' * Himantopetalum : ''P. caricinum, P. christiansenianum, P. pearcei, P. klotzscheanum, P. richteri, P. tetzl ...

Cypripedium Reginae
''Cypripedium reginae'', known as the showy lady's slipper, pink-and-white lady's-slipper, or the queen's lady's-slipper, is a rare lady's-slipper orchid native to northern North America. Although never common, this plant has vanished from much of its historical range due to habitat loss.Sokolski et al. (1997). "Axenic Seed Culture and Micropropagation of Cypripedium reginae" ''Selbyana'' 18(2): 172-182. It is the state flower of Minnesota. Etymology The species name ''reginae'' is Latin for "of a queen". Common names also include fairy queen, white wing moccasin, royal lady's slipper, and silver-slipper. Description Like other lady's slipper orchids (subfamily Cypripedioideae) the ''Cypripedium reginae'' has flowers with a pouch-shaped labellum. ''Cypripedium reginae'' is a large, terrestrial orchid, growing in height with many stems from the same rootstock. Each stem has three to five alternate, pubescent leaves. Each ovately shaped leaf grows up to long and broad. Floweri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cypripedium
''Cypripedium'' is a genus of 58 species and nothospecies of hardy Orchidaceae, orchids; it is one of five genera that together compose the subfamily of lady's slipper orchids (Cypripedioideae). They are widespread across much of the Northern Hemisphere, including most of Europe and Africa (Algeria) (one species), Russia, China, Central Asia, Canada the United States, Mexico, and Central America. They are most commonly known as slipper orchids, lady's slipper orchids, or ladyslippers; other common names include moccasin flower, camel's foot, squirrel foot, steeple cap, Venus' shoes, and whippoorwill shoe. An abbreviation used in trade journals is "''Cyp.''" The genus name is derived from Ancient Greek (), an early reference in Greek myth to Aphrodite, and (), meaning "sandal". Most of ''Cypripedium'' grow in temperate and subtropical climates, but some species grow in the tundra in Alaska and Siberia, which is an unusually cold habitat for orchids. Other species occur well i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cypripedium Acaule
''Cypripedium acaule'' is a species of flowering plant in the orchid family Orchidaceae. It is commonly referred to as the pink lady's slipper or moccasin flower. The specific epithet ''acaule'' means "lacking an obvious stem", a reference to its short underground stem, for which reason the plant is also known as the stemless lady's-slipper. It is the provincial flower of Prince Edward Island, Canada and the state wildflower of New Hampshire, United States. Description ''Cypripedium acaule'' is a perennial plant. It grows slowly and up to . Unlike most other species of ''Cypripedium'', the pouch of ''C. acaule'' opens in a slit that runs down the front of the labellum rather than a round opening. The plant consists of two plicate leaves near the ground. From between those leaves sprouts a long, pubescent stalk that bears a single pink flower. The sepals and petals tend to be yellowish-brown to maroon with a large pouch that is usually some shade of pink but can be nearly mage ...

Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
