Gastrodia Gunatillekeorum
''Gastrodia gunatillekeorum'' is a new species of potato orchid discovered in Sinharaja rainforest and described in 2020. Each with less 100 mature individuals, only three small populations have been discovered as yet. This plant was named after Nimal Gunatilleke and Savithri Gunatilleke. It is morphologically similar to ''Gastrodia spatulata'', which is native to Indonesia, due to both species having a white flower with yellowish-orange colouring on the inner wall of the perianth tube and the free part of perianth tube reflexed backwards. The two species however differ in respect to the spathulate to linear petals which are shorter than sepal A sepal () is a part of the flower of angiosperms (flowering plants).

Gastrodia
''Gastrodia'', commonly known as potato orchids or as 天麻属 (tian ma shu), is a genus of terrestrial leafless orchids in the family Orchidaceae, about ninety of which have been described. Orchids in this genus have fleshy, upright stems and small to medium-sized resupinate flowers with narrow sepals and petals. They are native to Asia (China, the Russian Far East, Japan, Korea, Southeast Asia, the Indian Subcontinent), Australia, New Zealand, central Africa, and various islands of the Indian and Pacific Oceans. Description Orchids in the genus ''Gastrodia'' are leafless, terrestrial, mycotrophic herbs with a fleshy, underground rhizome and an upright flowering stem with a few to many brownish, resupinate flowers. The sepals and petals are fused to form a bell-shaped or irregular tube with the tips free. The petals are usually much smaller than the sepals and the labellum has three lobes and is fully enclosed in the tube. Taxonomy The genus ''Gastrodia'' was first formally ...

Sinharaja Forest Reserve
Sinharaja Forest Reserve is a forest reserve and a biodiversity hotspot in Sri Lanka. It is of international significance and has been designated a Biosphere Reserve and World Heritage Site by UNESCO. According to International Union for Conservation of Nature (IUCN), Sinharaja is the country's last viable area of primary tropical rainforest. More than 60% of the trees are endemic and many of them are considered rare. 50% of Sri Lankan's endemics species of animals (especially butterfly, amphibians, birds, snakes and fish species). It is home to 95% endemic birds. The hilly virgin rainforest, part of the Sri Lanka lowland rain forests ecoregion, was saved from the worst of commercial logging by its inaccessibility, and was designated a World Biosphere Reserve in 1978 and a World Heritage Site in 1988. Because of the dense vegetation, wildlife is not as easily seen as at dry-zone national parks such as Yala. There are about 3 elephants, and 15 or so leopards. The most common l ...

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morphology (anatomy)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Friedrich Burdach ...

Gastrodia Spatulata
''Gastrodia spatulata'' is a species of ''Gastrodia'' native to Indonesia and Malaysia. It is known from Borneo and Java. Taxonomy It was first described by Cedric Errol Carr in 1935, from a dried specimen collected in the Penibukan range in Malaysia's Sabah state in 1933, as belonging to a new monotypic genus, and named ''Neoclemensia spathulata'', on the basis of details of the morphology of the flower -it has a shield-shaped stigma on top of a raised protuberance at the base of the column, as opposed to an oblong or broadly V-shaped stigma above the base of the column in the rest of ''Gastrodia'' known at the time. In 2011 Jeffrey James Wood and colleagues, having found it growing on Mount Kinabalu in Sabah, subsumed it into the genus ''Gastrodia'', apparently misspelling the specific epithet as "''spatulata''" as opposed to "''spathulata''". This mistake has been rectified by subsequent authors. Description It is morphologically similar to '' Gastrodia gunatillekeorum' ...

Perianth
The perianth (perigonium, perigon or perigone in monocots) is the non-reproductive part of the flower, and structure that forms an envelope surrounding the sexual organs, consisting of the calyx (sepals) and the corolla (petals) or tepals when called a perigone. The term ''perianth'' is derived from Greek περί (, "around") and άνθος (, "flower"), while ''perigonium'' is derived from περί () and γόνος (, "seed, sex organs"). In the mosses and liverworts (Marchantiophyta), the perianth is the sterile tubelike tissue that surrounds the female reproductive structure (or developing sporophyte). Flowering plants In flowering plants, the perianth may be described as being either dichlamydeous/heterochlamydeous in which the calyx and corolla are clearly separate, or homochlamydeous, in which they are indistinguishable (and the sepals and petals are collectively referred to as tepals). When the perianth is in two whorls, it is described as biseriate. While the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

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] |
Gastrodia Zeylanica
''Gastrodia zeylanica'' is a species of potato orchids which is endemic to Sri Lanka. It was added to the ''2007 Red list of Threatened Fauna and Flora of Sri Lanka'' as ' critically endangered', on the basis of it having only been collected from a few localities. Taxonomy It was first reported from Sri Lanka in 1864 by George Henry Kendrick Thwaites, who classified it as '' Gastrodia javanica'', this was followed by subsequent authors until 1906, when Rudolf Schlechter described the Sri Lankan specimens as a new species which he called ''G. zeylanica''. In 2019 it was synonymized as ''Demorchis zeylanica'' (''Demorchis'' is a synonym of ''Gastrodia''), by Mark Alwin Clements and David Lloyd Jones. Distribution It is native to southwest Sri Lanka. In the 1981 ''A Revised handbook to the flora of Ceylon'', Jayaweera mistakenly included illustrations of a ''Didymoplexis ''Didymoplexis'', commonly known as crystal orchids or as 双唇兰属 (shuang chun lan shu), is a g ...
