Ceratocentron Fesselii
''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 Nueva Ecija, officially the Province of Nueva Ecija ( tgl, Lalawigan ng Nueva Ecija , also ; ilo, Probinsia ti Nueva Ecija; pag, Luyag/Probinsia na Nueva Ecija; Kapampangan: ''Lalawigan/Probinsia ning Nueva Ecija''), is a landlocked province .... 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, over-collecting to keep up with demand in the international orchid trade has led to its decline.

Monotypic Taxon
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. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopod ...

Vandeae Genera
The Vandeae is a large monophyletic 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 horticulturally important, especially ''Vanda'' and ''Phalaenopsis''. Subtribes This tribe is subdivided into four subtribes:Simo-Droissart, M., Plunkett, G.

Species Endangered By Slash-and-burn
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. 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. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists 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. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes in zool ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
