Banksia Undata
''Banksia undata'', commonly known as urchin dryandra, is a species of shrub that is endemic to the southwest of Western Australia. It has sessile, wedge-shaped, wavy, serrated leaves, pale yellow flowers in heads of between 80 and 160, and later up to eight follicles in each head. Description ''Banksia undata'' is a shrub that typically grows to a height of but does not form a lignotuber. It has wavy, serrated, wedge-shaped leaves that are long and wide and sessile or on a very short petiole. There are between four and nine irregular teeth on each side of the leaves. The flowers are pale yellow, arranged in heads of between 80 and 160 with hairy egg-shaped to narrow lance-shaped involucral bracts long at the base of each head. The perianth is long, sometimes pinkish, and the pistil long. Flowering occurs from July to October up to eight egg-shaped to elliptical follicles, long form in each head. Taxonomy and naming This species was first formally described in 1848 by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 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. ...

Department Of Parks And Wildlife (Western Australia)
The Department of Parks and Wildlife (DPaW) was the department of the Government of Western Australia responsible for managing lands described in the ''Conservation and Land Management Act 1984'' and implementing the state's conservation and environment legislation and regulations. The minister responsible for the department was the Minister for the Environment. History The Department of Environment and Conservation (DEC) was separated on 30 June 2013, forming the Department of Parks and Wildlife (DPaW) and the Department of Environment Regulation (DER), both of which commenced operations on 1 July 2013. DPaW focused on managing multiple use state forests, national parks, marine parks and reserves. DER focused on environmental regulation, approvals and appeals processes, and pollution prevention. It was announced on 28 April 2017 that the Department of Parks and Wildlife would merge with the Botanic Gardens and Parks Authority, the Zoological Parks Authority and the Rott ...

Climate Change
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing m ...

Brookton Highway
Brookton Highway is a long undivided single carriageway highway in Western Australia, running from the southern Perth suburb of Kelmscott, through Westdale, to the southern Wheatbelt town of Brookton.

North Bannister, Western Australia
North Bannister is a small town located in the Wheatbelt region of Western Australia, south-southeast of the state capital, Perth along Albany Highway between Armadale and Williams. The town's name honours Thomas Bannister who discovered the nearby Bannister River, a tributary of the Hotham River, in 1830 while leading the first overland expedition from Perth to King George Sound (now Albany). The name was applied to the river in 1832 by surveyor-general John Septimus Roe.

Dwellingup, Western Australia
Dwellingup is a town in Western Australia located in a timber and fruitgrowing area in the Darling Range east-south-east of Pinjarra. At the 2011 census, Dwellingup had a population of 383. Name Townsite lots were surveyed at this place by surveyor W.F. Rudall in 1909 after the Lands Department became aware that the site was planned as the terminus of the "Pinjarra-Marrinup Railway". Names suggested for the place by Rudall were "Dwellingerup" or "Marrinup", after nearby brooks, or "McLarty" after a local MLA who had been very active concerning the railway. Surveyor General H.F. Johnston chose "Dwellingupp" after being misinformed regarding the spelling of Dwellingerup Brook. Ignoring a suggestion from the Under Secretary to amend the name to "Dwellingdown", the Minister for Lands approved the name as "Dwellingup" in December 1909. Eventually, the spelling "Dwellingupp" was chosen by order of the Under Secretary for Lands, and the townsite was gazetted as Dwellingupp in February ...
