Banksia Subser. Sphaerocarpae
''Banksia'' subser. ''Sphaerocarpae'' is a valid botanic name for a subseries of '' Banksia''. It was published by Kevin Thiele in 1996, but discarded by Alex George in 1999. Cladistics The name came about after a cladistic analysis of ''Banksia'' by Thiele and Pauline Ladiges yielded a phylogeny somewhat at odds with the accepted taxonomic arrangement, prompting them to publish a revised arrangement. Their cladogram contained a clade that corresponded closely to George's ''B.'' ser. ''Abietinae''. This clade resolved into four subclades, for which Thiele published four corresponding subseries. ''B.'' subser. ''Sphaerocarpae'' was based upon the third subclade: Taxonomy ''B.'' subser. ''Sphaerocarpae'' was formally defined as containing those taxa with "seeds with transversely aligned cells on the inner face on the inner face of the wing,... and old styles that curl loosely around the infructescence." In addition, all species except ''B. grossa'' have a pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Banksia Grossa
''Banksia grossa'' is a species of shrub in the family Proteaceae and is endemic to Southwest Australia. It is one of fourteen species of banksia of the series '' Abietinae'', all of which bear predominantly cylindrical or oval inflorescences. Collected in 1965, it was first formally described in 1981 by Alex George. Its thick leaves and large seeds distinguish it from other members of the ''Abietinae'', and are the basis of its species name. Found in sand or sand over laterite among heath between Eneabba and Badgingarra in Western Australia, it grows as a many-stemmed shrub to high with narrow leaves and oval brownish flower spikes up to high, composed of hundreds of individual flowers. Flowering occurs throughout the cooler months of March to September. Flower spikes develop woody follicles which bear the seeds. After bushfire, ''Banksia grossa'' regenerates from its woody lignotuber; bushfires also stimulate the release of seeds, which germinate after disturbance. Visito ...

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 ...

Banksiinae
''Banksia'' is a genus of around 170 species in the plant family Proteaceae. These Australian wildflowers and popular garden plants are easily recognised by their characteristic flower spikes, and fruiting "cones" and heads. ''Banksias'' range in size from prostrate woody shrubs to trees up to 30 metres (100 ft) tall. They are found in a wide variety of landscapes: sclerophyll forest, (occasionally) rainforest, shrubland, and some more arid landscapes, though not in Australia's deserts. Heavy producers of nectar, ''banksias'' are a vital part of the food chain in the Australian bush. They are an important food source for nectarivorous animals, including birds, bats, rats, possums, stingless bees and a host of invertebrates. Further, they are of economic importance to Australia's nursery and cut flower industries. However, these plants are threatened by a number of processes including land clearing, frequent burning and disease, and a number of species are rare species, rare and ...

DNA Sequence
DNA sequencing is the process of determining the nucleic acid sequence – the order of nucleotides in DNA. It includes any method or technology that is used to determine the order of the four bases: adenine, guanine, cytosine, and thymine. The advent of rapid DNA sequencing methods has greatly accelerated biological and medical research and discovery. Knowledge of DNA sequences has become indispensable for basic biological research, DNA Genographic Projects and in numerous applied fields such as medical diagnosis, biotechnology, forensic biology, virology and biological systematics. Comparing healthy and mutated DNA sequences can diagnose different diseases including various cancers, characterize antibody repertoire, and can be used to guide patient treatment. Having a quick way to sequence DNA allows for faster and more individualized medical care to be administered, and for more organisms to be identified and cataloged. The rapid speed of sequencing attained with modern D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Australian Biological Resources Study
Australian Biological Resources Study (ABRS) is a project undertaken by Parks Australia Division of Australia's Department of the Environment, Water, Heritage and the Arts (DEWHA). Background ABRS was founded in 1973 from the recommendations of a 1972 Senate Select Committee report on Wildlife Conservation. Its purpose is to collate from the many libraries, museums and other collections the taxonomy of Australia's estimated 2 million species of flora and fauna, including aquatic species. These represent almost 20% of the earth's biodiversity, 80% of which are unique to Australia. ABRS has undertaken active funding for taxonomic research of Australia's biodiversity and is internationally recognised for its extensive data bases and publications. Publications The most important outputs of the ABRS has been the publication of the multi-volume ''Flora of Australia'' and '' Fauna of Australia'' series. Other output includes ''The Banksia Atlas'' and the "Platypus" database pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Banksia Coccinea
''Banksia coccinea'', commonly known as the scarlet banksia, waratah banksia or Albany banksia, is an erect shrub or small tree in the family Proteaceae. Its distribution in the wild is along the south west coast of Western Australia, from Denmark to the Stokes National Park, and north to the Stirling Range, growing on white or grey sand in shrubland, heath or open woodland. Reaching up to in height, it is a single-stemmed plant that has oblong leaves, which are long and wide. The prominent red and white flower spikes appear mainly in the spring. As they age they develop small follicles that store seeds until opened by fire. Though widely occurring, it is highly sensitive to dieback and large populations of plants have succumbed to the disease. Collected and described by Robert Brown in the early 19th century, ''Banksia coccinea'' appears to be most closely related to ''Banksia speciosa'' and '' B. baxteri''. ''Banksia coccinea'' plants are killed by bushfire, and r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Banksia Ashbyi
''Banksia ashbyi'', commonly known as Ashby's banksia, is a species of shrub or small tree that is Endemism, endemic to Western Australia. It has smooth, grey bark, deeply serrated, hairy leaves and spikes of bright orange flowers. Description ''Banksia ashbyi'' is a shrub or small tree that typically grows to a height of and sometimes forms a lignotuber. It has smooth, grey bark and young stems that are hairy at first but become wikt:glabrous, glabrous as they age. The leaves are broadly linear, long and wide and deeply serrated, the serrations triangular with sharply pointed tips. The flower spikes are bright orange, long and in diameter, each perianth long. Flowering occurs from February to May or July to December and the fruits are numerous smooth, elliptical to round Follicle (fruit), follicles long, high and wide with a covering of short, soft hairs.

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) ...
