Ceratocentron
''Ceratocentron'' is a critically endangered monotypic genus of plants in the family Orchidaceae. It sole known species, ''Ceratocentron fesselii'', is found at high altitudes from Nueva Vizcaya and Nueva Ecija to the Cordillera Mountain ranges on Luzon island in the Philippines. The holotype was discovered in northern Nueva Ecija. The species is rare in the wild, and remained unknown to science until 1989.Senghas, Karlheinz. 1989. Die Orchideen Hamburg 40: 90 It is critically endangered due to habitat degradation and collecting. According to the IUCN The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status ..., over-collecting to keep up with demand in the international orchid trade has led to its decline.

Aeridinae
In the botanical classification of plants, Aeridinae Pfitzer is a subtribe of the tribe Vandeae (Family Orchidaceae) whose representatives all have a monopodial growth habit and do not possess pseudobulbs. This subtribe is a monophyletic group within Vandeae, and it contains more than 1,300 species in 103 genera, including about 208 (38%) hybrid genera. They occur mostly in Asia with a few in Africa. They are distinguished from the other subtribes of Vandeae by having an entire rostellum, a relatively small spur formed by the lip, and four (or two) pollinia. Some of the genera it contains have some of the largest and most spectacular flowers in the whole of the orchid family. Also included in this subtribe are some of the most economically important genera in the horticultural trade, such as ''Phalaenopsis'' and '' Vanda''. Leaflessness Aeridinae contains the largest diversity of leafless taxa within the tribe Vandeae. These leafless species of the genera '' Chiloschista'' ...

Nueva Ecija
Nueva Ecija, officially the Province of Nueva Ecija ( ; ; ; ), is a landlocked province in the Philippines located in the Central Luzon region. Its capital is the city of Palayan, while Cabanatuan, its former capital, is the largest Local government in the Philippines, local government unit (LGU). Nueva Ecija borders, from the south clockwise, Bulacan, Pampanga, Tarlac, Pangasinan, Nueva Vizcaya and Aurora (province), Aurora. The province is nationally known as the ''Rice Granary of the Philippines'', producing the largest rice yield in the country. History Early history These first settlers included tribes of Bugkalots or Italons, Abaca and Buquids. Settlements were built along the banks following the river's undulations. The Bugkalot, Ilongots, meaning people of the forest, were the fierce headhunters and animist tribes who occupied Carranglan and the mountainous terrain of Sierra Madre (Philippines), Sierra Madre and Caraballo Mountains. The head hunting communities were n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karlheinz Senghas
Karlheinz Senghas (7 April 1928 – 4 February 2004) was a German botanist and orchidologist. He was a curator, scientific director, and academic director of the University of Heidelberg's Botanical Garden from 1960 until his retirement in 1993. He was also president of the Deutsche Orchideen-Gesellschaft in the 1970s and was the co-publisher and editor of several volumes of ''Die Orchideen'', a continuation of the publication begun by Rudolf Schlechter Friedrich Richard Rudolf Schlechter (16 October 1872 – 16 November 1925) was a German taxonomist, botanist, and author of several works on orchids. He went on botanical expeditions in Africa, Indonesia, New Guinea, South and Central America an .... He described his first orchid species, '' Aerangis buchlohii'' in 1962. Over the years, he contributed more than 300 publications on orchids and established 17 new orchid genera and 388 species. Several genera and species are named in his honor, including the orchid genera '' S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species That Are Or Were Threatened By Urbanization
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Endangered Plants
In September 2016, the International Union for Conservation of Nature (IUCN) listed 3654 endangered plant species. Of all evaluated plant species, 17% are listed as endangered. The IUCN also lists 99 subspecies and 101 varieties as endangered. No subpopulations of plants have been evaluated by the IUCN. For a species to be considered endangered by the IUCN it must meet certain quantitative criteria which are designed to classify taxa facing "a very high risk of extinction". An even higher risk is faced by critically endangered species, which meet the quantitative criteria for endangered species. Critically endangered plants are listed separately. There are 6147 plant species which are endangered or critically endangered. Additionally 1674 plant species (7.6% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Luzon
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is ''funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. 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 ...

Endemic Orchids Of The Philippines
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

Monotypic Epidendroideae Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical system. ...

Vandeae Genera
The Vandeae is a large monophyly, monophyletic Tribe (biology), tribe within the family of orchids. Scope This tribe contains 1,700 - 2,000 species in more than 150 genera. Epiphytic These orchids are pantropical epiphytes and occur in tropical Asia, the Pacific Islands, Australia and Africa. Many of these orchids are horticulture, horticulturally important, especially ''Vanda'' and ''Phalaenopsis''.
