Rapateaceae
The Rapateaceae are a family of flowering plants. The botanical name has been recognized by most taxonomists. The APG II system of 2003 also recognizes this family, and assigns it to the order Poales in the clade commelinids, in the monocots. This represents a slight change from the APG system, 1998, which left the family unplaced as to order, but placed it in the same clade (although it used the spelling "commelinoids"). The family is divided into 16 genera with a total of about 94 known species, found in tropical South America and tropical west Africa. The Cronquist system of 1981 also recognized this family and placed it in the order Commelinales in the subclass Commelinidae in class Liliopsida in division Magnoliophyta Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants t .... Gene ...

Endemic
Endemism is the state of a species being found 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 be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kaieteur National Park
Kaieteur National Park is a national park located in the Potaro-Siparuni Region of Guyana. The Park's boundaries and purpose are defined in the Kaieteur National Park Act, and was created to preserve the natural scenery (including Kaieteur Falls), and its fauna and flora. There are organisms that are unique to this park and cannot be found anywhere else in the world. Of these organisms include the Anomaloglossus beebei, which is a frog that only inhabits the Brocchinia micrantha within this park and no where else in the world. The Act is administered by the Kaieteur National Park Commission. It is usually considered the country's only national park, as the capital's National Park is a not a wilderness reserve. The park is in the Guianan moist forests ecoregion. It is served by Kaieteur International Airport, which is at Kaieteur Falls.

Monotypic Poales 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. 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 trichopoda ...
