Neottieae
Neottieae is an orchid tribe in the subfamily Epidendroideae. It contains six genera and over 200 species distributed mainly in temperate and subtropical zones of the northern hemisphere. All its members are terrestrial plants, hinting at an early branching with Epidendroideae which is largely an epiphytic group. Neottieae is likely to be the result of a single temperate radiation of epidendroids, although it appears that some lineages in this tribe have crept back into the tropics. The genus '' Thaia'' had been tentatively included in this tribe, but is now placed in the tribe Thaieae. Palmorchis is sister to the other genera and was moved here from Palmorchideae based on molecular evidence. It is the only group in this tribe that occurs in Central and South America and is morphologically isolated. Etymology The name of this tribe was taken from one of its genera: ''Neottia'' Guett. (1754). This name refers to the particular shape of the tangled mass of roots of plants in thi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Limodorum
''Limodorum'' is a genus of myco-heterotrophic orchids. All species are temperate terrestrial plants and occur across much of Europe, North-West Africa, the Mediterranean Islands, and as far east as Iran. Plants have evolved away from photosynthesis and as a result their leaves are reduced to scales. There is still chlorophyll present but the plants are believed to be solely dependent on their fungal partner for nutrients. They spend most of their life underground as a short stem with fleshy roots, the unbranched inflorescence can appear in April to June if conditions are favourable. The name finds its origin in "haemodoron", first applied by Theophrastus and later adopted by Jacques Daléchamps to refer to parasitic plants most likely in Orobanche. The name is derived from the Greek “leimo-” (meadow) and “dōron,” (gift). Species A very long list of names has been proposed over the years. Most of these species, once part of ''Limodorum'', have been transferred to o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Taxonomy Of The Orchidaceae
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).

Aphyllorchis
''Aphyllorchis'', commonly known as pauper orchids or as 無葉蘭屬/无叶兰属 (wu ye lan shu), is a genus of about twenty species of terrestrial leafless orchids in the family Orchidaceae. Orchids in this genus have fleshy, upright stems and small to medium-sized resupinate flowers with narrow sepals and petals. They are native to a region extending from India east to China and Japan, south to Indonesia, New Guinea and Queensland. Description Orchids in the genus ''Aphyllorchis'' are leafless, terrestrial, mycotrophic herbs. A few to many flowers are borne on an erect, usually fleshy, unbranched flowering stem. The flowers are resupinate, more or less cup-shaped with the sepals and petals free from each other and similar in length but with the dorsal sepal curving forwards. The labellum is larger than the sepals and petals, boat-shaped and divided into two main sections, an upper "epichile" and lower "hypochile". The epichile is attached to the base of the column ...

Cephalanthera
''Cephalanthera'', abbreviated Ceph in horticultural trade, is a genus of mostly terrestrial orchids. Members of this genus have rhizomes rather than tubers. About 15 species are currently recognized, most of them native to Europe and Asia. The only species found in the wild in North America is ''Cephalanthera austiniae'', the phantom orchid or snow orchid. Ecologically, this species is partially myco-heterotrophic. Some of the Eurasian species hybridise. Several of the European species have common names including the word "helleborine", though orchids in other genera are also called helleborines. In addition to those listed here, very large numbers of other specific names will be found in the older literature, but these are almost all synonyms for the best known species such as ''C. longifolia'' or ''C. damasonium'', the European white helleborine. Species accepted as of May 2014 are: *'' Cephalanthera alpicola'' Fukuy. - Taiwan *''Cephalanthera austiniae'' (A.Gry) Heller - ...

Epipactis
''Epipactis'', or helleborine, is a genus of terrestrial orchids consisting of approximately 70 species. This genus is abbreviated as Epcts in horticultural trade. Description Their creeping, fleshy rhizomes grow offshoots, from which then emerge the 20–70 cm long stems during the next spring. There are four to eight alternate, lanceolate leaves, that grow progressively shorter near the top. The margins are entire, the top is acute. Species with less chlorophyll have blue-purple leaves. Their bilaterally symmetrical colorful flowers grow from a terminal raceme. The three sepals and the two lateral petals are ovate and acuminate. Their color can vary from greenish-white to violet and purple. The lip is divided in a bowl-shaped hypochile, with the outer surface greenish-white and threaded with dark veins. The wavy, snow-white epichile is fan-shaped. The ovary is inferior. It produces a dry capsule with countless minute seeds. Chemistry As is characteristic of all orch ...

Neottia
''Neottia'' is a genus of orchids. The genus now includes the former genus ''Listera'', commonly known as twayblades referring to the single pair of opposite leaves at the base of the flowering stem. The genus is native to temperate, subarctic and arctic regions across most of Europe, northern Asia (Siberia, China, the Himalayas, Central Asia, etc), and North America, with a few species extending into subtropical regions in the Mediterranean, Indochina, the southeastern United States, etc.Pridgeon, A.M., Cribb, P.J., Chase, M.C. & Rasmussen, F.N. (2006). Epidendroideae (Part One). Genera Orchidacearum 4: 1-672. Oxford University Press, New York, Oxford. ''Neottia'' produces a racemose inflorescences with flowers in shades of green or dull pink through to maroon and purple. The lip of each flower is prominently forked or two-lobed. Some species (those which were previously the only members of the genus ''Neottia'' in the strict sense, such as the bird's-nest orchid, ''Neottia n ...

Epidendroideae
Epidendroideae is a subfamily of plants in the orchid family, Orchidaceae. Epidendroideae is larger than all the other orchid subfamilies together, comprising more than 15,000 species in 576 genera. Most epidendroid orchids are tropical epiphytes, typically with pseudobulbs. There are, however, some terrestrials such as ''Epipactis'' and even a few myco-heterotrophs, which are parasitic upon mycorrhizal fungi. They typically contain the remaining orchids with a single, fertile anther ( = monandrous), which is also fully incumbent ( = strongly convex) to suberect (= ascending towards the edges). The anther form arises from column elongation or, as in the vandoids, from early anther bending. The incumbent anther forms a right angle with the column axis or is pointed backward in many genera. Most have hard pollinia, i.e. a mass of waxy pollen or of coherent pollen grains. The pollinia are with caudicle and viscidium or without. The stigma are entire or three-lobed; a beak is prese ...
