Robert Allen Rolfe
Robert Allen Rolfe (1855, Wilford, Nottinghamshire – 1921, Richmond, Surrey) was an English botanist specialising in the study of orchids. For a time he worked in the gardens at Welbeck Abbey. He entered Kew in 1879 and became second assistant. He was the first curator of the orchid herbarium at the Royal Botanic Gardens, Kew, founded the magazine ''The Orchid Review'', and published many papers on hybrids of different species of orchids. The genus ''Allenrolfea'' of amaranths was named after him by Carl Ernst Otto Kuntze. Rolfe was buried in Richmond Cemetery Richmond Cemetery is a cemetery on Lower Grove Road in Richmond in the London Borough of Richmond upon Thames, England.

Gastrodin
Gastrodin is a chemical compound which is the glucoside of gastrodigenin. It has been isolated from the orchid ''Gastrodia elata'' and from the rhizome of ''Galeola faberi''. It can also be produced by biotransformation of 4-hydroxybenzaldehyde by '' Datura tatula'' cell cultures. ''G. elata'' is a herb used in traditional Chinese medicine to treat headache, and it is standardized in the Chinese Pharmacopoeia by gastrodin and gastrodigenin content. In line with this traditional use, gastrodin and its acetyl derivative are used in China as an over-the-counter drug to treat neurasthenia, headache, and migraine. It is available as a dietary supplement in other countries. A Chinese literature review considers it useful for a range of central nervous system The central nervous system (CNS) is the part of the nervous system consisting primarily of the brain and spinal cord. The CNS is so named because the brain integrates the received information and coordinates and influences the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myco-heterotrophic Orchids
Myco-heterotrophy (from Greek μύκης , "fungus", ἕτερος ', "another", "different" and τροφή ', "nutrition") is a symbiotic relationship between certain kinds of plants and fungi, in which the plant gets all or part of its food from parasitism upon fungi rather than from photosynthesis. A myco-heterotroph is the parasitic plant partner in this relationship. Myco-heterotrophy is considered a kind of cheating relationship and myco-heterotrophs are sometimes informally referred to as "mycorrhizal cheaters". This relationship is sometimes referred to as mycotrophy, though this term is also used for plants that engage in mutualistic mycorrhizal relationships. Relationship between myco-heterotrophs and host fungi Full (or obligate) myco-heterotrophy exists when a non-photosynthetic plant (a plant largely lacking in chlorophyll or otherwise lacking a functional photosystem) gets all of its food from the fungi that it parasitizes. Partial (or facultative) myco-heterotr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orchids Of Yunnan
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).

Flora Of Sumatra
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or ''skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de Phyt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Galeola
''Galeola'' is a genus of orchids (family Orchidaceae) belonging to the subfamily Vanilloideae. All species in this genus are myco-heterotrophic, i.e. they are parasitic upon fungi. The genus is spread throughout southeast Asia (from India to China to New Guinea) as well as Madagascar and Comoros. ''Galeola'' is of biological interest because of its exclusive myco-heterotrophic nature and its seeds. The seeds are the biggest orchid seeds in the world. They are winged, which is also extraordinary for an orchid. Species At present, there are 6 currently recognized species: *''Galeola cathcarthii'' Hook.f. (Thailand, Myanmar, India, Assam, Bhutan, Sikkim) *''Galeola faberi'' Rolfe (China, Assam, Nepal, Vietnam, Sumatra) *''Galeola falconeri'' Hook.f. (India, Taiwan, Assam, Bhutan, Nepal, Thailand, Vietnam, China) *''Galeola humblotii'' H.G.Reichb. (Madagascar, Comoros) *''Galeola lindleyana'' (Hook.f. & J.W.Thomson) H.G.Reichb.
