Banksia Elegans
''Banksia elegans'', commonly known as the elegant banksia, is a species of woody shrub that is Endemism, endemic to a relatively small area of Western Australia. Reaching high, it is a suckering shrub that rarely reproduces by seed. The round to oval yellow flower spikes appear in spring and summer. Swiss botanist Carl Meissner described ''Banksia elegans'' in 1856. It is most closely related to the three species in the Banksia subg. Isostylis, subgenus ''Isostylis''. Description ''Banksia elegans'' grows as a many-stemmed spreading shrub to high. It commonly sends up suckers from either the roots or trunk. The trunk is up to in diameter and covered with grey tessellated bark. The new stems are covered with fine hair and become smooth with maturity. New growth mainly occurs in summer. The long thin pale blue-green leaves are long and wide. Their margins are prominently serrated in a saw-tooth pattern with triangular teeth and v-shaped sinuses. The yellow flower spikes, or i ...

Perth, Western Australia
Perth is the capital and largest city of the Australian state of Western Australia. It is the fourth most populous city in Australia and Oceania, with a population of 2.1 million (80% of the state) living in Greater Perth in 2020. Perth is part of the South West Land Division of Western Australia, with most of the metropolitan area on the Swan Coastal Plain between the Indian Ocean and the Darling Scarp. The city has expanded outward from the original British settlements on the Swan River, upon which the city's central business district and port of Fremantle are situated. Perth is located on the traditional lands of the Whadjuk Noongar people, where Aboriginal Australians have lived for at least 45,000 years. Captain James Stirling founded Perth in 1829 as the administrative centre of the Swan River Colony. It was named after the city of Perth in Scotland, due to the influence of Stirling's patron Sir George Murray, who had connections with the area. It gained city stat ...

Pollen-presenter
A pollen-presenter is an area on the tip of the style in flowers of plants of the family Proteaceae on which the anthers release their pollen prior to anthesis. To ensure pollination, the style grows during anthesis, sticking out the pollen-presenter prominently, and so ensuring that the pollen easily contacts the bodies of potential pollination vectors such as bees, birds and nectarivorous mammals. The systematic depositing of pollen on the tip of the style implies the plants have some strategy to avoid excessive self-pollination Self-pollination is a form of pollination in which pollen from the same plant arrives at the stigma of a flower (in flowering plants) or at the ovule (in gymnosperms). There are two types of self-pollination: in autogamy, pollen is transferred .... References * Plant anatomy + Proteaceae {{Botany-stub ...

Banksia Attenuata
''Banksia attenuata'', commonly known as the candlestick banksia, slender banksia, or biara to the Noongar people, is a species of plant in the family Proteaceae. Commonly a tree, it reaches high, but it is often a shrub in drier areas high. It has long, narrow, serrated leaves and bright yellow inflorescences, or flower spikes, held above the foliage, which appear in spring and summer. The flower spikes age to grey and swell with the development of the woody follicle (fruit), follicles. The candlestick banksia is found across much of the Southwest Australia, southwest of Western Australia, from north of Kalbarri National Park down to Cape Leeuwin and across to Fitzgerald River National Park. English botanist John Lindley had named material collected by Australian botanist James Drummond (botanist), James Drummond ''Banksia cylindrostachya'' in 1840, but this proved to be the same as the species named ''Banksia attenuata'' by Scottish botanist Robert Brown (botanist, born 1773) ...

Austin Mast
Austin R. Mast is a research botanist. Born in 1972, he obtained a Ph.D. from the University of Wisconsin–Madison in 2000. He is currently a professor within the Department of Biological Science at Florida State University (FSU), and has been director of FSU's Robert K. Godfrey Herbarium since August 2003. One of his main areas of research is the phylogenetics of Grevilleoideae, a subfamily of Proteaceae. In 2005 he showed the genus ''Banksia'' to be paraphyletic with respect to ''Dryandra'', Collaborating with Australian botanist Kevin Thiele, he subsequently transferred all ''Dryandra'' taxa to ''Banksia'', publishing over 120 taxonomic names in the process. The change has been adopted by the Western Australian Herbarium, although has met with some controversy. He has previously worked on the Deep South Plant Specimen Imaging Project, which created a repository of annotated high-resolution digital images of plant specimens within the East Gulf Coastal Plain The Gulf Coastal ...

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.

Banksia Cuneata
''Banksia cuneata'', commonly known as matchstick banksia or Quairading banksia, is an endangered species of flowering plant in the family Proteaceae. Endemic to Southwest Australia, southwest Western Australia, it belongs to Banksia subg. Isostylis, ''Banksia'' subg. ''Isostylis'', a sub-genus of three closely related ''Banksia'' species with inflorescences or flower clusters that are dome-shaped heads rather than characteristic ''Banksia'' flower spikes. A shrub or small tree up to high, it has prickly foliage and pink and cream flowers. The common name ''Matchstick Banksia'' arises from the blooms in late bud, the individual buds of which resemble matchsticks. The species is pollination, pollinated by honeyeaters (Meliphagidae). Although ''B. cuneata'' was first collected before 1880, it was not until 1981 that Australian botanist Alex George (botanist), Alex George formally described and named the species. There are two genetically distinct population groups, but no re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Banksia Ilicifolia
''Banksia ilicifolia'', commonly known as holly-leaved banksia, is a tree in the family Proteaceae. Endemic to southwest Western Australia, it belongs to ''Banksia'' subg. ''Isostylis'', a subgenus of three closely related ''Banksia'' species with inflorescences that are dome-shaped heads rather than characteristic ''Banksia'' flower spikes. It is generally a tree up to tall with a columnar or irregular habit. Both the scientific and common names arise from the similarity of its foliage to that of the English holly ''Ilex aquifolium''; the glossy green leaves generally have very prickly serrated margins, although some plants lack toothed leaves. The inflorescences are initially yellow but become red-tinged with maturity; this acts as a signal to alert birds that the flowers have opened and nectar is available. Robert Brown described ''Banksia ilicifolia'' in 1810. Although ''Banksia ilicifolia'' is variable in growth form, with low coastal shrubby forms on the south coast nea ...

Conserved Name
A conserved name or ''nomen conservandum'' (plural ''nomina conservanda'', abbreviated as ''nom. cons.'') is a scientific name that has specific nomenclatural protection. That is, the name is retained, even though it violates one or more rules which would otherwise prevent it from being legitimate. ''Nomen conservandum'' is a Latin term, meaning "a name to be conserved". The terms are often used interchangeably, such as by the ''International Code of Nomenclature for Algae, Fungi, and Plants'' (ICN), while the ''International Code of Zoological Nomenclature'' favours the term "''conserved name''". The process for conserving botanical names is different from that for zoological names. Under the botanical code, names may also be "suppressed", ''nomen rejiciendum'' (plural ''nomina rejicienda'' or ''nomina utique rejicienda'', abbreviated as ''nom. rej.''), or rejected in favour of a particular conserved name, and combinations based on a suppressed name are also listed as “''nom. re ...

Principle Of Priority
270px, '' valid name. Priority is a fundamental principle of modern botanical nomenclature and zoological nomenclature. Essentially, it is the principle of recognising the first valid application of a name to a plant or animal. There are two aspects to this: # The first formal scientific name given to a plant or animal taxon shall be the name that is to be used, called the valid name in zoology and correct name in botany (principle of synonymy). # Once a name has been used, no subsequent publication of that name for another taxon shall be valid (zoology) or validly published (botany) (principle of homonymy). Note that nomenclature for botany and zoology is independent, and the rules of priority regarding homonyms operate within each discipline but not between them. There are formal provisions for making exceptions to the principle of priority under each of the Codes. If an archaic or obscure prior name is discovered for an established taxon, the current name can be declared ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pimelea
''Pimelea'', commonly known as rice flowers, is a genus of plants belonging to the family Thymelaeaceae. There are about 150 species, including 110 in Australia and thirty six in New Zealand. Description Plants in the genus ''Pimelea'' are herbs or small shrubs usually with leaves arranged in opposite pairs. The leaves are usually paler on the lower surface and the petiole is usually very short. The flowers are usually arranged in groups on the ends of the branches and have no petals but four petal-like sepals and two stamens. The ovary has a single ovule and the fruit is usually a nut containing a single seed. Taxonomy and naming The genus ''Pimelea'' was first formally described in 1788 by Joseph Gaertner from unpublished descriptions by Joseph Banks and Daniel Solander. The first species Gaertner described was ''Pimelea laevigata'', now known as ''Pimelea prostrata''. The name ''Pimelea'' is from the Ancient Greek word ''pimele'' meaning "fat or "lard", possibly referring ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Georg Forster
Johann George Adam Forster, also known as Georg Forster (, 27 November 1754 – 10 January 1794), was a German naturalist, ethnologist, travel writer, journalist and revolutionary. At an early age, he accompanied his father, Johann Reinhold Forster, on several scientific expeditions, including James Cook's second voyage to the Pacific. His report of that journey, ''A Voyage Round the World'', contributed significantly to the ethnology of the people of Polynesia and remains a respected work. As a result of the report, Forster, who was admitted to the Royal Society at the early age of twenty-two, came to be considered one of the founders of modern scientific travel literature. After returning to continental Europe, Forster turned toward academia. He taught natural history at the Collegium Carolinum in the Ottoneum, Kassel (1778–84), and later at the Academy of Vilna (Vilnius University) (1784–87). In 1788, he became head librarian at the University of Mainz. Most of his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Reinhold Forster
Johann Reinhold Forster (22 October 1729 – 9 December 1798) was a German Continental Reformed church, Reformed (Calvinist) pastor and natural history, naturalist of partially Scottish descent who made contributions to the early ornithology of Europe and North America. He is best known as the naturalist on James Cook's Second voyage of James Cook, second Pacific voyage, where he was accompanied by his son Georg Forster. These expeditions promoted the career of Johann Reinhold Forster and the findings became the bedrock of colonial professionalism and helped set the stage for the future development of anthropology and ethnology. They also laid the framework for general concern about the impact that alteration of the physical environment for European economic expansion would have on exotic societies. Biography Forster's family originated in the Lord Forrester, Lords Forrester in Scotland from where his great-grandfather had emigrated after losing most of his property during the ...
