Resupination
Resupination is derived from the Latin word ''resupinus'', meaning "bent back with the face upward" or "on the back". "Resupination" is the noun form of the adjective "resupine" which means "being upside-down, supine or facing upward". The word "resupinate" is generally only used in a botanical context – in everyday language, "supine" has a similar meaning. In botany, resupination refers to the "twisting" of flowers or leaves through about 180° as they open. Resupinate leaves have the petiole or "stalk" twisted - resupinate flowers twist as they open. Botanical examples Alstroemeriaceae Plants in the genus ''Alstroemeria'' have more or less resupinate leaves. Orchidaceae The flower of a typical plant in the orchid family Orchidaceae has three sepals and three petals. One petal, called the labellum, "lip" or "tongue", is typically quite different from the other two. It usually functions to attract an insect pollinator. As an orchid flower bud develops, the attachment o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orchids Of The Philippines
There are about 141 genera of orchids representing about 1,100 orchid species, 900 of which are described as endemic to the Philippines. Many of them have showy, brightly colored and attractive flowers. ''Vanda sanderiana'' is unofficially dubbed the National Flower, as the only representative of the species is unique to the Philippines and is only found on the island of Mindanao.

Orchids Of New Guinea
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] |

Dienia
''Dienia'', commonly called snout orchids, is a genus of six species of orchids in the family Orchidaceae. Plants in this genus are evergreen, mostly terrestrial plants with a fleshy, above ground stem, large, pleated leaves and small, non-resupinate flowers with thin sepals and petals. The labellum is short and tongue-like. The genus is distributed in Southeast Asia, Australia, Micronesia and Melanesia. Description Orchids in the genus ''Dienia'' are evergreen, sympodial, mostly terrestrial plants with fleshy, above-ground stems, although a few species are epiphytes. There are between three and six relatively large, thin, pleated leaves with their petioles wrapped around the stem. Small, non-resupinate flowers are borne along the end of the flowering stem. The flowers are green, brown, yellow, pink, or purple and have narrow sepals and petals. The sepals are oblong to egg-shaped and spread widely and the petals are usually narrower than the sepals.

Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine. Dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Botanical Nomenclature
Botanical nomenclature is the formal, scientific naming of plants. It is related to, but distinct from Alpha taxonomy, taxonomy. Plant taxonomy is concerned with grouping and classifying plants; botanical nomenclature then provides names for the results of this process. The starting point for modern botanical nomenclature is Carl Linnaeus, Linnaeus' ''Species Plantarum'' of 1753. Botanical nomenclature is governed by the ''International Code of Nomenclature for algae, fungi, and plants'' (''ICN''), which replaces the ''International Code of Botanical Nomenclature'' (''ICBN''). Fossil plants are also covered by the code of nomenclature. Within the limits set by that code there is another set of rules, the ''International Code of Nomenclature for Cultivated Plants, International Code of Nomenclature for Cultivated Plants (ICNCP)'' which applies to plant cultivars that have been deliberately altered or selected by humans (see cultigen). History and scope Botanical nomenclature has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gunnar Seidenfaden
Gunnar Seidenfaden (1908 – February 9, 2001) was a Danish diplomat and botanist. He was Danish ambassador in Thailand 1955–1959, and in the U.S.S.R. 1959–1961. He was an expert on Southeast Asia Orchidaceae. He published several multi-volume works on orchids, e.g. ''The Orchids of Thailand – A Preliminary List'' (with T. Smitinand) and ''Orchid Genera in Thailand'' vol. I- XIV. These works are strictly taxonomic and floristic, but decorated with Seidenfaden's own drawings of flower parts as seen under the dissection microscope. His collection of more than 10,000 specimens was donated to the University of Copenhagen, together with original drawings by Katja Anker and others. In June 2016, it was decided that the collection of orchid samples, which was held in the Danish capital botanical garden Botanisk Have, part of the natural history museum Statens Naturhistoriske Museum, would be returned to Thailand. The reason given was that many of the specimens have become quite rare ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Gerhard König
Johann Gerhard König (29 November 1728 – 26 June 1785) was a Baltic German botanist and physician who served in the Tranquebar Mission, India before joining service under the Nawab of Arcot, and then the English East India Company. He collected natural history specimens including plants, particularly those of medical interest, from the region and several species are named after him including the curry tree ''(Murraya'' ''koenigii).'' Biography König was born near ''Kreutzburg'' in Polish Livonia, which is now Krustpils in Latvia. He was a private pupil of Carl Linnaeus in 1757, and lived in Denmark from 1759 to 1767 during which time he examined the plants of Iceland. In 1767 he joined as a medical officer to the Tranquebar Mission and on his voyage to India, he passed through Cape Town where he met Governor Rijk Tulbagh with an introduction from Linnaeus, collecting plants in the Table Mountain region from 1 to 28 April 1768. König replaced the position made available ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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] |
