Orbexilum Melanocarpum
''Orbexilum'', commonly called leather-root, is a genus of flowering plants in the legume family (Fabaceae). They are native to North America, where they are found in the United States and Mexico, south to Chiapas. This genus can be distinguished from other genera in the Psoraleeae by its "thick glabrous pod walls that are distinctively rugose and by calyx that is scarcely accrescent." Taxonomy The genus was described by Constantine Samuel Rafinesque in 1832, with the type species ''O. latifolia'', moved from ''Psoralea''. (''O. latifolia'' is now considered a synonym of ''O. onobrychis''.) Rafinesque differentiated ''Orbexilum'' from ''Psoralea'' largely on the basis of features of the calyx. Species ''Orbexilum'' comprises the following species: * ''Orbexilum chiapasanum'' B.L.Turner * '' Orbexilum lupinellus'' (Michx.) Isely * †'' Orbexilum macrophyllum'' (Rowlee) Rydb. – bigleaf scurfpea * '' Orbexilum melanocarpum'' (Benth.) Rydb. * ''Orbexilum oliganth ...

Species
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 i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Apposition
Apposition is a grammatical construction in which two elements, normally noun phrases, are placed side by side so one element identifies the other in a different way. The two elements are said to be ''in apposition'', and one of the elements is called the appositive, but its identification requires consideration of how the elements are used in a sentence. For example, in these sentences, the phrases ''Alice Smith'' and ''my sister'' are in apposition, with the appositive identified with italics: * My sister, ''Alice Smith'', likes jelly beans. * Alice Smith, ''my sister'', likes jelly beans. Traditionally, appositions were called by their Latin name ''appositio'', derived from the Latin ''ad'' ("near") and ''positio'' ("placement"), although the English form is now more commonly used. Apposition is a figure of speech of the scheme type and often results when the verbs (particularly verbs of being) in supporting clauses are eliminated to produce shorter descriptive phrases.

Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Orbexilum Stipulatum
''Orbexilum stipulatum'', commonly known as largestipule leather-root or Falls-of-the-Ohio scurfpea, was a flowering plant that was endemic to Rock Island in the Falls of the Ohio; an area of rapids and rocky limestone outcrops in Kentucky's portion of the Ohio River. No live individuals have been found since 1881 and it is presumed to be extinct. Overview ''Orbexilum stipulatum'' is thought to have been associated with large herbivore congregations. Rock Island in the Falls of the Ohio area was the shallowest part of the Ohio River, which historically was heavily used for the migration of American buffalo. The plant's population may have collapsed following the eradication of buffalo. If this factor alone had not extirpated ''Orbexilum stipulatum'' already, Rock Island and the associated rapids were flooded in the 1920s by the creation of US Dam 41, which sealed the fate for ''Orbexilum stipulatum'' at the Falls of the Ohio.
