Banksia Saxicola
''Banksia saxicola'', the rock banksia or Grampians banksia, is a species of tree or shrub in the plant genus '' Banksia''. It occurs in Victoria in two distinct populations, one in The Grampians and the other on Wilsons Promontory. Formerly considered to be a form of ''B. integrifolia'', it was described as a distinct species by Alex George in 1981. It is most closely related to '' Banksia marginata''. Near the coast, ''B. saxicola'' grows as a tree to high, while in alpine areas it is a shrub that grows up to high, or in exposed areas. It has leathery green leaves and grey-yellow inflorescences (flower spikes) which appear in summer and early autumn. The old flowers fall off the spikes, followed by the development of finely furred follicles. Description ''Banksia saxicola'' grows as a tall upright tree to high at Wilsons Promontory, or as a sprawling shrub in the Grampians. At the latter location, plants maintain their spreading habit even in more sheltered parts, re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alex George (botanist)
Alexander Segger George (born 4 April 1939) is a Western Australian botanist. He is the authority on the plant genera ''Banksia'' and ''Dryandra''. The "bizarre" Restionaceae genus '' Alexgeorgea'' was named in his honour in 1976. Early life Alex Segger George was born in Western Australia on 4 April 1939. Career George joined the Western Australian Herbarium as a laboratory assistant at the age of twenty in 1959. He worked under Charles Gardner for a year before the latter's retirement, and partly credits him with rekindling an interest in banksias. In 1963 he graduated with a Bachelor of Arts from the University of Western Australia, and the following year added a botany major. Continuing at the Western Australian Herbarium as a botanist, in 1968 he was seconded as Australian Botanical Liaison Officer at the Royal Botanic Gardens in London. George also has an interest in history, especially historical biography of naturalists in Western Australia. He has published a number ...

Mount William (Mount Duwil)
Mount William (also Mount Duwil) is a mountain of the Grampians Mountain Range, located within the Grampians National Park, in the Australian state of Victoria. The mountain is situated approximately west-northwest of Melbourne on the eastern edge of the national park, approximately drive from Halls Gap. Features and location Mount William is the highest point within the Grampians National Park. Sir Thomas Mitchell reached the summit with a group of explorers in 1836. The first settler in the area was Horatio Wills, who established a sheep run at Mount William in 1840, and named nearby Mount Ararat, after which the town is named. His son, cricketer and Australian rules football pioneer Tom Wills, grew up as a lone white child among the Djab wurrung Aboriginal tribes of Mount William. Three transmission towers are located at the summit of Mount William including an amateur radio repeater. A sealed service road continues to the summit, but is not accessible by vehicle to th ...

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 ...

Banksia Paludosa
''Banksia paludosa'', commonly known as the marsh or swamp banksia, is a species of shrub in the plant genus ''Banksia''. It is native to New South Wales, Australia, where it is found between Sydney and Batemans Bay, with an isolated population further south around Eden. There are two recognised subspecies, the nominate of which is a spreading shrub to in height, and subsp. ''astrolux'' is a taller shrub to high found only in Nattai National Park. Native mammals, such as the brown antechinus and sugar glider, are important pollinators of ''B. paludosa''. Several species of honeyeaters visit the flower spikes, as do ants and the European honey bee. The response to bushfire depends on the subspecies; subspecies ''paludosa'' regenerates from underground lignotubers, while plants of subspecies ''astrolux'' are killed by fire and regenerate from large stores of seed which have been held in cones in the plant canopy. ''B. paludosa'' is sometimes seen in cultivation, with dwarf form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Banksia Conferta
''Banksia conferta'', commonly known as the glasshouse banksia, is a species of shrub that is endemic to eastern Australia. It has rough, bark on the trunk, elliptic to egg-shaped leaves arranged in whorls, crowded yellow flowers in a cylindrical spike later forming a relatively large number of follicles. Description ''Banksia conferta'' is a shrub that typically grows to a height of but does not form a lignotuber. It has rough, grey, tessellated bark on the trunk and orange, red or brown stems that are hairy at first. The leaves are arranged in whorls and are elliptic to egg-shaped with the narrower end towards the base, long and wide with the edges curved downwards and sometimes serrated. The flowers are crowded in a cylindrical spike long with involucral bracts long at the base. The flowers are yellowish green to pinkish brown in the bud stage, turning golden yellow when open. The perianth is long and the pistil is long and slightly curved. Flowering occurs from late ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Banksia Robur
''Banksia robur'', commonly known as swamp banksia, or less commonly broad-leaved banksia, grows in sand or peaty sand in coastal areas from Cooktown in north Queensland to the Illawarra region on the New South Wales south coast. It is often found in areas which are seasonally inundated. Although it was one of the original banksias collected by Joseph Banks around Botany Bay in 1770, it was not named until 1800 by Cavanilles, with a type collection by Luis Née in 1793. Description ''Banksia robur'' is a spreading shrub to , although it can get a little larger in cultivation. It has very large, leathery tough green leaves with serrated margins up to long and wide. The new growth is colourful, in shades of red, maroon or brown with a dense felt-like covering of brown hairs. Plants from different areas seem to flower at different times, some in spring and summer, others predominantly in autumn. The stunning large flower spikes, up to high and wide, are metallic green with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Banksia Oblongifolia
''Banksia oblongifolia'', commonly known as the fern-leaved, dwarf or rusty banksia, is a species in the plant genus ''Banksia''. Found along the eastern coast of Australia from Wollongong, New South Wales in the south to Rockhampton, Queensland in the north, it generally grows in sandy soils in heath, open forest or swamp margins and wet areas. A many-stemmed shrub up to high, it has leathery serrated leaves and rusty-coloured new growth. The yellow flower spikes, known as inflorescences, most commonly appear in autumn and early winter. Up to 80 follicles, or seed pods, develop on the spikes after flowering. ''Banksia oblongifolia'' resprouts from its woody lignotuber after bushfires, and the seed pods open and release seed when burnt, the seed germinating and growing on burnt ground. Some plants grow between fires from seed shed spontaneously. Spanish botanist Antonio José Cavanilles described ''B. oblongifolia'' in 1800, though it was known as ''Banksia aspleniifoli ...

Banksia Plagiocarpa
''Banksia plagiocarpa'', commonly known as Dallachy's blue banksia, blue banksia or Hichinbrook banksia, is a species of shrub or tree in the plant genus ''Banksia''. It occurs only on Hinchinbrook Island, Queensland and the immediately adjacent mainland. First collected in 1867, ''Banksia plagiocarpa'' was not described until 1981, when Alex George named it in his monograph of the genus ''Banksia''. Genetic studies show it to be related to '' Banksia aquilonia'', ''Banksia oblongifolia'' and ''Banksia robur''. Description ''Banksia plagiocarpa'' grows as a shrub to high with greyish broken bark. The new growth is covered in red velvety fur, which falls off after two or three years. The long narrow lanceolate (spear-shaped) to obovate leaves are arranged alternately along the stems. Measuring long by wide, they have recurved margins lined with blunt serrations. Appearing from February to July, the flower spikes, known as inflorescences, are high and in diameter at anthesis ...

Banksia Aquilonia
''Banksia aquilonia'', commonly known as the northern banksia and jingana, is a tree in the family Proteaceae and is endemic to north Queensland on Australia's northeastern coastline. With an average height of , it has narrow glossy green leaves up to long and high pale yellow flower spikes, known as inflorescences, appearing in autumn. As the spikes age, their flowers fall off and they develop up to 50 follicles, each of which contains two seeds. Alex George described the plant in his 1981 monograph of the genus ''Banksia'' as a variety of ''Banksia integrifolia'', but later reclassified it as a separate species. Genetic studies show it to be related to ''Banksia plagiocarpa'', ''Banksia oblongifolia'' and ''Banksia robur''. The species is found in wet sclerophyll forest and rainforest margins on sandy soils. ''Banksia aquilonia'' regenerates after bushfire by regrowing from epicormic buds under its bark. It is rarely cultivated. Description ''Banksia aquilonia'' grows as a ...

Banksia Dentata
''Banksia dentata'', commonly known as the tropical banksia, is a species of tree in the genus ''Banksia''. It occurs across northern Australia, southern New Guinea and the Aru Islands. Growing as a gnarled tree to high, it has large green leaves up to long with dentate (toothed) margins. The cylindrical yellow inflorescences (flower spikes), up to high, appear over the cooler months, attracting various species of honeyeaters, sunbirds, the sugar glider and a variety of insects. Flowers fall off the ageing spikes, which swell and develop follicles containing up to two viable seeds each. ''Banksia dentata'' is one of four ''Banksia'' species collected by Sir Joseph Banks in 1770, and one of the four species published in 1782 as part of Carolus Linnaeus the Younger's original description of ''Banksia''. Within the genus, it is classified in the series ''Salicinae'', a group of species from Australia's eastern states. Genetic studies show it is a basal member (early offsh ...

Banksia Ser
''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 and endangered. ...

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] |
