Acacia Parramattensis
''Acacia parramattensis'', commonly known as Parramatta wattle, is a tree of the family Fabaceae native to the Blue Mountains (Australia), Blue Mountains and surrounding regions of New South Wales. It is a tall shrub or tree to about in height with phyllodes (flattened leaf stalks) instead of true leaves. These are finely divided bipinnate . The yellow flowers appear over summer. It generally grows in woodland or dry sclerophyll forest on alluvial or shale-based soils, generally with some clay content. A fast-growing plant, it regenerates after bushfire by seed or Basal shoot, suckering and can quickly colonise disturbed areas. Likewise it adapts readily to cultivation and is used in revegetation projects. Description Growing with an upright Habit (biology), habit, ''Acacia parramattensis'' is a tall shrub or tree ranging from in height with smooth bark that can be dark green, dark brown or black. The branchlets are more or less terete (round in cross-section), sometimes with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mary Tindale
Mary Douglas Tindale (19 September 1920 β 31 March 2011) was an Australian botanist specialising in pteridology (ferns) and the genera ''Acacia'' and ''Glycine''. Tindale was born in Randwick, New South Wales, the only child of George Harold Tindale and Grace Matilda Tindale. She attended primary school in New York while her father served as British Ambassador to the United States. She returned to Sydney, Australia to attend high school at Abbotsleigh.

Acacia Mearnsii
''Acacia mearnsii'', commonly known as black wattle, late black wattle or green wattle, is a species of flowering plant in the family Fabaceae and is endemic to south-eastern Australia. It is usually an erect tree with smooth bark, bipinnate leaves and spherical heads of fragrant pale yellow or cream-coloured flowers followed by black to reddish brown pods. In some other parts of the world, it is regarded as an invasive species. Description ''Acacis mearnsii'' is a spreading shrub or erect tree that typically grows to a height of and has smooth bark, sometimes corrugated at the base of old specimens. The leaves are bipinnate with 7 to 31 pairs of pinnae, each with 25 to 78 pairs of pinnules. There is a spherical gland up to below the lowest pair of pinnae. The scented flowers are arranged in spherical heads of twenty to forty and are pale yellow or cream-coloured, the heads on hairy peduncles long. Flowering mainly occurs from October to December and black to reddish-brown ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yengo National Park
The Yengo National Park is a protected national park that is located in the Lower Hunter region of New South Wales, in eastern Australia. The park is situated northwest of the Sydney central business district, south of , north of , and southwest of . The average elevation of the terrain is 309 meters. The Yengo National Park is one of the eight protected areas that, in 2000, was inscribed to form part of the UNESCO World Heritagelisted Greater Blue Mountains Area. The Yengo National Park is the most northeasterly of the eight protected areas within the World Heritage Site. The national park forms part of the Great Dividing Range. Features The NSW National Parks and Wildlife Service (NPWS) opened their depot in Bucketty in 1993 and commenced managing the newly established Yengo National Park. A helipad, known as 'Bucketty International' was established and in 1995 a fire tower was built, following severe fires in the area. In 1999 the NPWS acquired parts of the Crown land t ...

Sydney Basin
The Sydney Basin is an interim Australian bioregion and is both a structural entity and a depositional area, now preserved on the east coast of New South Wales, Australia and with some of its eastern side now subsided beneath the Tasman Sea. The basin is named for the city of Sydney, on which it is centred. Around thick, the Sydney Basin consists of Permian and Triassic sedimentary rocks, which stretches from Newcastle in the north to Batemans Bay in the south, and west to the Great Dividing Range. The basin is also home to the major centres of Newcastle and Wollongong, New South Wales, Wollongong, and contains economically significant reserves of coal. Sydney's famous Port Jackson, harbour and the sculptured cliffs of the Blue Mountains (New South Wales), Blue Mountains are signature formations of relatively hard upper strata of sandstone. The basin contains the UNESCO World Heritage Site, UNESCO World Heritage-listed Greater Blue Mountains Area. Geography According to De ...

Polyphyly
A polyphyletic group is an assemblage of organisms or other evolving elements that is of mixed evolutionary origin. The term is often applied to groups that share similar features known as homoplasies, which are explained as a result of convergent evolution. The arrangement of the members of a polyphyletic group is called a polyphyly .. ource for pronunciation./ref> It is contrasted with monophyly and paraphyly. For example, the biological characteristic of warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds; "warm-blooded animals" is therefore a polyphyletic grouping. Other examples of polyphyletic groups are algae, C4 photosynthetic plants, and edentates. Many taxonomists aim to avoid homoplasies in grouping taxa together, with a goal to identify and eliminate groups that are found to be polyphyletic. This is often the stimulus for major revisions of the classification schemes. Researchers concerned more with ecology than with system ...

Chloroplast DNA
Chloroplast DNA (cpDNA) is the DNA located in chloroplasts, which are photosynthetic organelles located within the cells of some eukaryotic organisms. Chloroplasts, like other types of plastid, contain a genome separate from that in the cell nucleus. The existence of chloroplast DNA was identified biochemically in 1959, and confirmed by electron microscopy in 1962. The discoveries that the chloroplast contains ribosomes and performs protein synthesis revealed that the chloroplast is genetically semi-autonomous. The first complete chloroplast genome sequences were published in 1986, ''Nicotiana tabacum'' (tobacco) by Sugiura and colleagues and ''Marchantia polymorpha'' (liverwort) by Ozeki et al. Since then, a great number of chloroplast DNAs from various species have been sequenced. Molecular structure Chloroplast DNAs are circular, and are typically 120,000β170,000 base pairs long. They can have a contour length of around 30β60 micrometers, and have a mass of about 80β ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genomic DNA
Genomic deoxyribonucleic acid (abbreviated as gDNA) is chromosomal DNA, in contrast to extra-chromosomal DNAs like plasmids. Most organisms have the same genomic DNA in every cell; however, only certain genes are active in each cell to allow for cell function and differentiation within the body. The genome of an organism (encoded by the genomic DNA) is the (biological) information of heredity which is passed from one generation of organism to the next. That genome is transcribed to produce various RNAs, which are necessary for the function of the organism. Precursor mRNA (pre-mRNA) is transcribed by RNA polymerase II in the nucleus. pre-mRNA is then processed by splicing to remove introns, leaving the exons in the mature messenger RNA (mRNA). Additional processing includes the addition of a 5' cap and a poly(A) tail to the pre-mRNA. The mature mRNA may then be transported to the cytosol and translated by the ribosome into a protein. Other types of RNA include ribosomal RNA (rR ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subgenus
In biology, a subgenus (plural: subgenera) is a taxonomic rank directly below genus. In the International Code of Zoological Nomenclature, a subgeneric name can be used independently or included in a species name, in parentheses, placed between the generic name and the specific epithet: e.g. the tiger cowry of the Indo-Pacific, ''Cypraea'' (''Cypraea'') ''tigris'' Linnaeus, which belongs to the subgenus ''Cypraea'' of the genus ''Cypraea''. However, it is not mandatory, or even customary, when giving the name of a species, to include the subgeneric name. In the International Code of Nomenclature for algae, fungi, and plants (ICNafp), the subgenus is one of the possible subdivisions of a genus. There is no limit to the number of divisions that are permitted within a genus by adding the prefix "sub-" or in other ways as long as no confusion can result. Article 4 The secondary ranks of section and series are subordinate to subgenus. An example is ''Banksia'' subg. ''Isostylis'', ...

Section (botany)
In botany, a section ( la, sectio) is a taxonomic rank below the genus, but above the species. The subgenus, if present, is higher than the section, and the rank of series, if present, is below the section. Sections may in turn be divided into subsections.Article 4 in Sections are typically used to help organise very large genera, which may have hundreds of species. A botanist wanting to distinguish groups of species may prefer to create a taxon at the rank of section or series to avoid making new combinations, i.e. many new binomial names for the species involved. Examples: * ''Lilium'' sectio ''Martagon'' Rchb. are the Turks' cap lilies * ''Plagiochila aerea'' Taylor is the type species of ''Plagiochila'' sect. ''Bursatae'' See also * Section (biology) References Section Section, Sectioning or Sectioned may refer to: Arts, entertainment and media * Section (music), a complete, but not independent, musical idea * Section (typography), a subdivision, especially ...

Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia le ...

Racosperma
''Acacia'', commonly known as the wattles or acacias, is a large genus of shrubs and trees in the subfamily Mimosoideae of the pea family Fabaceae. Initially, it comprised a group of plant species native to Africa and Australasia. The genus name is New Latin, borrowed from the Greek (), a term used by Dioscorides for a preparation extracted from the leaves and fruit pods of ''Vachellia nilotica'', the original type of the genus. In his ''Pinax'' (1623), Gaspard Bauhin mentioned the Greek from Dioscorides as the origin of the Latin name. In the early 2000s it had become evident that the genus as it stood was not monophyletic and that several divergent lineages needed to be placed in separate genera. It turned out that one lineage comprising over 900 species mainly native to Australia, New Guinea, and Indonesia was not closely related to the much smaller group of African lineage that contained ''A. nilotica''βthe type species. This meant that the Australasian lineage (b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
