North American Atlantic Region
North American Atlantic Region is a floristic region within the Holarctic Kingdom identified by Armen Takhtajan and Robert F. Thorne, spanning from the Atlantic and Gulf coasts to the Great Plains and comprising a major part of the United States and southeastern portions of Canada. It is bordered by the Circumboreal floristic region in the north, by the Rocky Mountain and Madrean floristic regions in the west and by the Caribbean floristic region of the Neotropical Kingdom in the south of Florida. The flora of the region comprises two endemic monotypic families, Hydrastidaceae and Leitneriaceae, and is characterized by about a hundred of endemic genera (such as ''Sanguinaria'', ''Leavenworthia'', ''Gillenia'', '' Neviusia'', '' Dionaea'', '' Yeatesia'', '' Pleea''). The degree of species endemism is very high, many species are Tertiary relicts, which survived the Wisconsin glaciation and are now concentrated in the Appalachians (esp. Blue Ridge Mountains) and the Ozarks. A number ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phylogenetic Species Concept
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 zoologic ...

Pacific Coast Ranges
The Pacific Coast Ranges (officially gazetted as the Pacific Mountain System in the United States) are the series of mountain ranges that stretch along the West Coast of North America from Alaska south to Northern and Central Mexico. Although they are commonly thought to be the westernmost mountain range of the continental United States and Canada, the geologically distinct Insular Mountains of Vancouver Island lie further west. The Pacific Coast Ranges are part of the North American Cordillera (sometimes known as the Western Cordillera, or in Canada, as the Pacific Cordillera and/or the Canadian Cordillera), which includes the Rocky Mountains, the Columbia Mountains, the Interior Mountains, the Interior Plateau, the Sierra Nevada, the :Mountain ranges of the Great Basin, Great Basin mountain ranges, and other ranges and various plateaus and basins. The Pacific Coast Ranges designation, however, only applies to the Western System of the Western Cordillera,S. Holland, ''Landforms ...

Viburnum Ellipticum
''Viburnum ellipticum'', the common viburnum or oval-leaved viburnum, is a species of shrub in family Adoxaceae. It is native to the western United States from Washington to central California, where it occurs in forests and mountain chaparral habitat. The shrub has deciduous leaves with oval or rounded blades 2 to 6 centimeters long. The leaf blade usually has three main longitudinal veins and a shallowly toothed edge. The inflorescence is a flat-topped cyme of many white flowers each 6 to 8 millimeters wide with five whiskery white stamens. The fruit is a drupe In botany, a drupe (or stone fruit) is an indehiscent fruit in which an outer fleshy part (exocarp, or skin, and mesocarp, or flesh) surrounds a single shell (the ''pit'', ''stone'', or '' pyrena'') of hardened endocarp with a seed (''kernel'') ... about a centimeter long.

Molecular Phylogenetics
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Josef August Schultes
Josef (Joseph) August Schultes (15 April 1773 in Vienna – 21 April 1831 in Landshut) was an Austrian botanist and professor from Vienna. Together with Johann Jacob Roemer (1763–1819), he published the 16th edition of Linnaeus' ''Systema Vegetabilium''. In 1821, he was elected a foreign member of the Royal Swedish Academy of Sciences. He was the father of Julius Hermann Schultes (1804-1840). In 1796 he received his doctorate at Vienna, where he was a student of Johann Peter Frank (1745-1821). Later on, he served as a professor of botany and natural history at the Theresianum in Vienna, followed by professorships at the Universities of Krakow (1806) and Innsbruck (1808). In 1809 he succeeded Franz von Paula Schrank (1747-1835) at the University of Landshut as a professor of natural history and botany. At Landshut, he also served as a medical director. Swedish botanist Carl Peter Thunberg commissioned Schultes to edit the first complete edition of his Flora Capensis, which ...

Viburnum Rafinesqueanum
''Viburnum rafinesqueanum'', the downy arrowwood, is a deciduous medium-sized (typically about 2 meters tall) shrub native to the Eastern United States and Canada from Quebec and Manitoba south to Georgia and west to Oklahoma. Downy arrow-wood produces ornamental but slightly malodorous flowers in Spring. ''Viburnum rafinesqueanum'' has opposite, simple leaves and dark blue fruit in berry-like drupe In botany, a drupe (or stone fruit) is an indehiscent fruit in which an outer fleshy part (exocarp, or skin, and mesocarp, or flesh) surrounds a single shell (the ''pit'', ''stone'', or '' pyrena'') of hardened endocarp with a seed (''kernel'') ...s. Foliage turns orange-red in late fall. Southern arrow-wood ('' V. dentatum'') is similar, except that it blooms later and has broader, more coarsely toothed leaves and longer petioles. Other similar species are smooth arrowwood ('' V. recognitum'') and Carolina arrowwood ('' V. carolinianum''). References External links {{Taxonb ...

Variety (botany)
In botanical nomenclature, variety (abbreviated var.; in la, varietas) is a taxonomic rank below that of species and subspecies, but above that of form. As such, it gets a three-part infraspecific name. It is sometimes recommended that the subspecies rank should be used to recognize geographic distinctiveness, whereas the variety rank is appropriate if the taxon is seen throughout the geographic range of the species. Example The pincushion cactus, ''Escobaria vivipara'' (Nutt.) Buxb., is a wide-ranging variable species occurring from Canada to Mexico, and found throughout New Mexico below about . Nine varieties have been described. Where the varieties of the pincushion cactus meet, they intergrade. The variety ''Escobaria vivipara'' var. ''arizonica'' is from Arizona, while ''Escobaria vivipara'' var. ''neo-mexicana'' is from New Mexico. See also '' Capsicum annuum var. glabriusculum'' Definitions The term is defined in different ways by different authors. However, the I ...
