Banksia Incana
''Banksia incana'', commonly known as the hoary banksia, is a species of shrub that is endemic to the south-west of Western Australia. It has hairy stems, narrow linear leaves, heads of bright yellow flowers and later, up to thirty-six follicles covered with greyish hairs in each head. Description ''Banksia incana'' grows as a shrub, typically high and wide with many stems arising from a woody lignotuber. The stems are covered woolly, greyish hairs. The leaves are narrow linear, long and wide on petiole long and with a sharp point on the tip. The flowers are borne on a spherical head in diameter. The flowers are bright yellow, sometimes reddish, the perianth long and the pistil long and hooked. Flowering occurs from November to April and up to thirty-six prominent, egg-shaped follicles, long, high and wide form in each head, the old flowers having fallen. The follicles are covered with short, greyish hairs. Taxonomy Carl Meissner noted the hoary banksia as a distinc ... [...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 ...

Banksia Leptophylla
''Banksia leptophylla'' is a species of shrub that is endemic to the south-west of Western Australia. It has narrow linear leaves, heads of yellow or pale brown flowers with a yellow or purple style and later, up to eight egg-shaped follicles in each head. Description ''Banksia leptophylla'' is a much-branched shrub that typically grows to tall and wide but does not form a lignotuber. It has narrow linear leaves long and wide on a petiole long. The flowers are borne on a head long on a short side branch. The flowers are pale yellow or pale brown with a perianth long and hooked pistil long. Flowering occurs from January to December and the follicles are elliptic, in heads of eighty or more, each follicle long, high and wide. Taxonomy and naming ''Banksia leptophylla'' was first formally described in 1981 by Alex George in the journal ''Nuytsia''.

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 ...

Gingin, Western Australia
Gingin is a town in Western Australia, located on the Brand Highway north of the Perth city centre. It is the council seat for the Shire of Gingin local government area. Gingin had a population of 852 at the . The town's economy is mostly based on its agriculture, although there has been an increasing focus on science with the establishment of the Australian International Gravitational Observatory and Gravity Discovery Centre. There is also a small military airfield, RAAF Gingin, located nearby. History The first European to visit the area was the explorer George Fletcher Moore; he arrived in 1836 and recorded the Aboriginal name "Jinjin" on his charts. The first property to be established in the area by William Locke Brockman in 1841 was named Gingin station. The meaning of the word Gingin is uncertain but is thought to mean "footprint" or "place of many streams". A townsite, Granville, was established close by in 1839 but once Gingin was gazetted in 1871 Granville was ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disjunct Distribution
In biology, a taxon with a disjunct distribution is one that has two or more groups that are related but considerably separated from each other geographically. The causes are varied and might demonstrate either the expansion or contraction of a species' range. Range fragmentation Also called range fragmentation, disjunct distributions may be caused by changes in the environment, such as mountain building and continental drift or rising sea levels; it may also be due to an organism expanding its range into new areas, by such means as rafting, or other animals transporting an organism to a new location (plant seeds consumed by birds and animals can be moved to new locations during bird or animal migrations, and those seeds can be deposited in new locations in fecal matter). Other conditions that can produce disjunct distributions include: flooding, or changes in wind, stream, and current flows, plus others such as anthropogenic introduction of alien introduced species either acciden ...

Arrowsmith River
The Arrowsmith River lies within the Mid West region of Western Australia. The explorer George Grey found the river on 11 April 1839, on his second expedition along the west coast. He named it after the distinguished English cartographer John Arrowsmith. The river commences just south of Arrino and north-west of Three Springs near the Midlands Road and flows in a westerly direction for a length of to the coast and terminates in Arrowsmith Lake, inland from Cliff Head. The river drops a total of in elevation over the course of its length. Flooding in surrounding areas occurred in 1932 following a torrential downpour that caused the river and surrounding creeks to rise and flood a few hours later. The salinity levels in the river are often higher than 1000 mg/L due to brackish Brackish water, sometimes termed brack water, is water occurring in a natural environment that has more salinity than freshwater, but not as much as seawater. It may result from mixing seawat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Banksia Menziesii
''Banksia menziesii'', commonly known as firewood banksia, is a species of flowering plant in the genus ''Banksia''. It is a gnarled tree up to tall, or a lower spreading shrub in the more northern parts of its range. The serrated leaves are dull green with new growth a paler grey green. The prominent autumn and winter inflorescences are often two-coloured red or pink and yellow, and their colour has given rise to more unusual common names such as port wine banksia and strawberry banksia. Yellow blooms are rarely seen. First described by the botanist Robert Brown in the early 19th century, no separate varieties of ''Banksia menziesii'' are recognised. It is found in Western Australia, from the Perth (32° S) region north to the Murchison River (27° S), and generally grows on sandy soils, in scrubland or low woodland. ''Banksia menziesii'' provides food for a wide array of invertebrate and vertebrate animals; birds and in particular honeyeaters are prominent visitors. A re ...

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) ...
