Gastrolobium Grandiflorum
''Gastrolobium grandiflorum'', commonly known as wallflower poison, wallflower poison bush or heart-leaf poison bush, is a bushy shrub which is endemic to Australia. It grows to 2 or 3 metres in height and between late summer and early winter (February to August in Australia) it produces orange-red pea-flowers with a yellow centre and red veins. The leaves are hairy and heart-shaped on younger plants and elliptic and more glabrous on older plants, up to 6 cm long and 2.7 cm wide. The species was first formally described by botanist Ferdinand von Mueller and published in ''Fragmenta Phytographiae Australiae'' in 1863. It is the most widespread within the genus, occurring across a large area of Queensland, as well as in the Northern Territory, Western Australia and South Australia. Poisonous attributes The species, like many others within the genus ''Gastrolobium'', contains high levels of fluoroacetate (the active ingredient in the pest control toxin known as 1080) T ...

Endemic (ecology)
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or bec ...

David Carnegie (explorer)
David Wynford Carnegie (23 March 1871 – 27 November 1900) was an explorer and gold prospector in Western Australia. In 1896 he led an expedition from Coolgardie through the Gibson and Great Sandy Deserts to Halls Creek, and then back again. Early life David Carnegie was born in London on 23 March 1871, the youngest child of James Carnegie, 9th Earl of Southesk. He was educated at Charterhouse in Godalming, Surrey but dropped out without graduating, and was thereafter educated by a private tutor. He later entered the Royal Indian Engineering College, but again dropped out without completing the course. In 1892, he travelled to Ceylon to work on a tea plantation. Finding it boring, he quit after a few weeks, and set sail for Australia with his friend Lord Percy Douglas. Gold prospecting On arriving in Albany, Western Australia in September 1892, Carnegie and Douglas learned of Arthur Bayley's discovery of gold at Coolgardie, and immediately decided to leave the ship ...

Rosids Of Western Australia
The rosids are members of a large clade (monophyletic group) of flowering plants, containing about 70,000 species, more than a quarter of all angiosperms. The clade is divided into 16 to 20 orders, depending upon circumscription and classification. These orders, in turn, together comprise about 140 families. Fossil rosids are known from the Cretaceous period. Molecular clock estimates indicate that the rosids may have originated in the Aptian or Albian stages of the Cretaceous, between 125 and 99.6 million years ago. Today's broadleaved forests are dominated by rosid species, which in turn help with diversification in many other living lineages. Additionally, rosid herbs and shrubs are a significant part of arctic/alpine and temperate floras. The clade also includes some aquatic, desert and parasitic plants. Name The name is based upon the name " Rosidae", which had usually been understood to be a subclass. In 1967, Armen Takhtajan showed that the correct basis for the na ...

Flora Of South Australia
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms '' gut flora'' or '' skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) ...

Halls Creek, Western Australia
Halls Creek is a town situated in the east Kimberley region of Western Australia. It is located between the towns of Fitzroy Crossing and Turkey Creek (Warmun) on the Great Northern Highway. It is the only sizable town for 600 km on the Highway. Halls Creek is also the northern end of the Canning Stock Route, which runs 1,850 km through the Great Sandy Desert until the southern end of the route at Wiluna. The town functions as a major hub for the local Indigenous population and as a support centre for cattle stations in the area. Halls Creek is the administration centre for Halls Creek Shire Council. History The land now known as Halls Creek has been occupied for thousands of years by Aboriginal peoples. The land is crossed by songlines and trading paths stretching from the coasts to the deserts, some passing near the modern town. The story of that long occupation remains alive today and it is revealed in the culture of the Jaru, Kija, Kukatja, Walmajarri, ...

Coolgardie, Western Australia
Coolgardie is a small town in Western Australia located around east of the state capital, Perth; and southwest of Kalgoorlie. It has a population of approximately 850 people. Although Coolgardie is now known to most Western Australians as a tourist town and a mining ghost town, it was once the third largest town in Western Australia (after Perth and Fremantle). At this time, mining of alluvial gold was a major industry and supplied the flagging economy with new hope. Many miners suffered under the harsh conditions, but for a few, their find made the hard work worthwhile. Most men, however, left poorer than they had started off, with their hopes dashed. History Coolgardie was founded in 1892, when gold was discovered in the area known as Fly Flat by prospectors Arthur Wellesley Bayley and William Ford. Australia had seen several major gold rushes over the previous three decades, mostly centred on the east coast, but these had mostly been exhausted by the 1890s. With the d ...
