Swainsona Formosa
''Swainsona formosa'', Sturt's desert pea, is an Australian plant in the genus '' Swainsona'', named after English botanist Isaac Swainson, famous for its distinctive blood-red leaf-like flowers, each with a bulbous black centre, or "boss". It is one of Australia's best known wildflowers. It is native to the arid regions of central and north-western Australia, and its range extends into all mainland Australian states with the exception of Victoria. Description Sturt's desert pea is a member of Fabaceae, subfamily Faboideae. It has pinnate, grey-green leaves which are arranged spirally on the main axis of the plant, and in two opposite rows (distichous) on lateral stems. Flower Its flowers are so different from its relatives that it is almost unrecognisable as a member of the pea family. The flowers are about 9 centimetres in length and grow in clusters of around half a dozen on thick vertical stalks ( peduncles), which spring up every 10-15 centimetres along the prostra ...

George Don
George Don (29 April 1798 – 25 February 1856) was a Scottish botanist and plant collector. Life and career George Don was born at Doo Hillock, Forfar, Angus, Scotland on 29 April 1798 to Caroline Clementina Stuart and George Don (b.1756), principal gardener of the Royal Botanic Garden Edinburgh in 1802. Don was the elder brother of David Don, also a botanist. He became foreman of the gardens at Chelsea in 1816. In 1821, he was sent to Brazil, the West Indies and Sierra Leone to collect specimens for the Royal Horticultural Society. Most of his discoveries were published by Joseph Sabine, although Don published several new species from Sierra Leone. Don's main work was his four volume ''A General System of Gardening and Botany'', published between 1832 and 1838 (often referred to as Gen. Hist., an abbreviation of the alternative title: ''A General History of the Dichlamydeous Plants''). He revised the first supplement to Loudon's ''Encyclopaedia of Plants'', and provided a ...

Legume
A legume () is a plant in the family Fabaceae (or Leguminosae), or the fruit or seed of such a plant. When used as a dry grain, the seed is also called a pulse. Legumes are grown agriculturally, primarily for human consumption, for livestock forage and silage, and as soil-enhancing green manure. Well-known legumes include beans, soybeans, chickpeas, peanuts, lentils, lupins, mesquite, carob, tamarind, alfalfa, and clover. Legumes produce a botanically unique type of fruit – a simple dry fruit that develops from a simple carpel and usually dehisces (opens along a seam) on two sides. Legumes are notable in that most of them have symbiotic nitrogen-fixing bacteria in structures called root nodules. For that reason, they play a key role in crop rotation. Terminology The term ''pulse'', as used by the United Nations' Food and Agriculture Organization (FAO), is reserved for legume crops harvested solely for the dry seed. This excludes green beans and green peas, which a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crown Land
Crown land (sometimes spelled crownland), also known as royal domain, is a territorial area belonging to the monarch, who personifies the Crown. It is the equivalent of an entailed estate and passes with the monarchy, being inseparable from it. Today, in Commonwealth realms such as Canada and Australia, crown land is considered public land and is apart from the monarch's private estate. In Britain, the hereditary revenues of Crown lands provided income for the monarch until the start of the reign of George III, when the profits from the Crown Estate were surrendered to the Parliament of Great Britain in return for a fixed civil list payment. The monarch retains the income from the Duchy of Lancaster. Australia In Australia, public lands without a specific tenure (e.g. National Park or State Forest) are referred to as Crown land or State Land, which is described as being held in the "right of the Crown" of either an individual State or the Commonwealth of Australia; there is ...

Endangered
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bladder Senna
''Colutea arborescens'' is a species of leguminous shrub known by the common name bladder-senna. It is native to Europe and North Africa, but it is known on other continents where it is grown as an ornamental and used in landscaping for erosion control. It is also known in the wild as an occasionally weedy escapee from cultivation. Description It is a vigorous shrub to 3 m, takes a rounded form and has many branches covered in deciduous leaves. The leaves are pale green and made up of many pairs of slightly hairy oval-shaped leaflets, each up to about 3 cm long. The inflorescence is a raceme A raceme ( or ) or racemoid is an unbranched, indeterminate type of inflorescence bearing flowers having short floral stalks along the shoots that bear the flowers.

Taproot
A taproot is a large, central, and dominant root from which other roots sprout laterally. Typically a taproot is somewhat straight and very thick, is tapering in shape, and grows directly downward. In some plants, such as the carrot, the taproot is a storage organ so well developed that it has been cultivated as a vegetable. The taproot system contrasts with the adventitious or fibrous root system of plants with many branched roots, but many plants that grow a taproot during germination go on to develop branching root structures, although some that rely on the main root for storage may retain the dominant taproot for centuries, for example ''Welwitschia''.Taproot also store nutrition. Plants with taproots are often vegetables. Description Dicots, one of the two divisions of flowering plants (angiosperms), start with a taproot, which is one main root forming from the enlarging radicle of the seed. The tap root can be persistent throughout the life of the plant but is most oft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pilbara
The Pilbara () is a large, dry, thinly populated region in the north of Western Australia. It is known for its Aboriginal peoples; its ancient landscapes; the red earth; and its vast mineral deposits, in particular iron ore. It is also a global biodiversity hotspot for subterranean fauna. Definitions of the Pilbara region At least two important but differing definitions of "the Pilbara" region exist. Administratively it is one of the nine regions of Western Australia defined by the ''Regional Development Commissions Act 1993''; the term also refers to the Pilbara shrublands bioregion (which differs in extent) under the Interim Biogeographic Regionalisation for Australia (IBRA). General The Pilbara region, as defined by the Regional Development Commissions Act 1993 and administered for economic development purposes by the Pilbara Development Commission, has an estimated population of 61,688 , and covers an area of .

Charles Sturt
Charles Napier Sturt (28 April 1795 – 16 June 1869) was a British officer and explorer of Australia, and part of the European exploration of Australia. He led several expeditions into the interior of the continent, starting from Sydney and later from Adelaide. His expeditions traced several of the westward-flowing rivers, establishing that they all merged into the Murray River, which flows into the Southern Ocean. He was searching to prove his own passionately held belief that an " inland sea" was located at the centre of the continent. He reached the rank of Captain, served in several appointed posts, and on the Legislative Council. Born to British parents in Bengal, British India, Sturt was educated in England for a time as a child and youth. He was placed in the British Army because his father was not wealthy enough to pay for Cambridge. After assignments in North America, Sturt was assigned to accompany a ship of convicts to Australia in 1827. Finding the place to his lik ...

Taxonomy (biology)
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolu ...
