Taxonomy (biology)
–
Taxonomy is the science of defining groups of biological organisms on the basis of shared characteristics and giving names to those groups. The exact definition of taxonomy varies from source to source, but the core of the remains, the conception, naming. There is some disagreement as to whether biological nomenclature is considered a part of taxonomy, the broadest meaning of taxonomy is used here. The word taxonomy was introduced in 1813 by Candolle, in his Théorie élémentaire de la botanique, the term alpha taxonomy is primarily used today to refer to the discipline of finding, describing, and naming taxa, particularly species. In earlier literature, the term had a different meaning, referring to morphological taxonomy, ideals can, it may be said, never be completely realized. They have, however, a value of acting as permanent stimulants. Some of us please ourselves by thinking we are now groping in a beta taxonomy, turrill thus explicitly excludes from alpha taxonomy various areas of study that he includes within taxonomy as a whole, such as ecology, physiology, genetics, and cytology. He further excludes phylogenetic reconstruction from alpha taxonomy, thus, Ernst Mayr in 1968 defined beta taxonomy as the classification of ranks higher than species. This activity is what the term denotes, it is also referred to as beta taxonomy. How species should be defined in a group of organisms gives rise to practical and theoretical problems that are referred to as the species problem. The scientific work of deciding how to define species has been called microtaxonomy, by extension, macrotaxonomy is the study of groups at higher taxonomic ranks, from subgenus and above only, than species. While some descriptions of taxonomic history attempt to date taxonomy to ancient civilizations, earlier works were primarily descriptive, and focused on plants that were useful in agriculture or medicine. There are a number of stages in scientific thinking. Early taxonomy was based on criteria, the so-called artificial systems. Later came systems based on a complete consideration of the characteristics of taxa, referred to as natural systems, such as those of de Jussieu, de Candolle and Bentham. The publication of Charles Darwins Origin of Species led to new ways of thinking about classification based on evolutionary relationships and this was the concept of phyletic systems, from 1883 onwards. This approach was typified by those of Eichler and Engler, the advent of molecular genetics and statistical methodology allowed the creation of the modern era of phylogenetic systems based on cladistics, rather than morphology alone. Taxonomy has been called the worlds oldest profession, and naming and classifying our surroundings has likely been taking place as long as mankind has been able to communicate

Plant
–
Plants are mainly multicellular, predominantly photosynthetic eukaryotes of the kingdom Plantae. The term is generally limited to the green plants, which form an unranked clade Viridiplantae. This includes the plants, conifers and other gymnosperms, ferns, clubmosses, hornworts, liverworts, mosses and the green algae. Green plants have cell walls containing cellulose and obtain most of their energy from sunlight via photosynthesis by primary chloroplasts and their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic and have lost the ability to produce amounts of chlorophyll or to photosynthesize. Plants are characterized by sexual reproduction and alternation of generations, although reproduction is also common. There are about 300–315 thousand species of plants, of which the great majority, green plants provide most of the worlds molecular oxygen and are the basis of most of Earths ecologies, especially on land. Plants that produce grains, fruits and vegetables form humankinds basic foodstuffs, Plants play many roles in culture. They are used as ornaments and, until recently and in variety, they have served as the source of most medicines. The scientific study of plants is known as botany, a branch of biology, Plants are one of the two groups into which all living things were traditionally divided, the other is animals. The division goes back at least as far as Aristotle, who distinguished between plants, which generally do not move, and animals, which often are mobile to catch their food. Much later, when Linnaeus created the basis of the system of scientific classification. Since then, it has become clear that the plant kingdom as originally defined included several unrelated groups, however, these organisms are still often considered plants, particularly in popular contexts. When the name Plantae or plant is applied to a group of organisms or taxon. The evolutionary history of plants is not yet settled. Those which have been called plants are in bold, the way in which the groups of green algae are combined and named varies considerably between authors. Algae comprise several different groups of organisms which produce energy through photosynthesis, most conspicuous among the algae are the seaweeds, multicellular algae that may roughly resemble land plants, but are classified among the brown, red and green algae. Each of these groups also includes various microscopic and single-celled organisms

Flowering plant
–
The flowering plants, also known as Angiospermae or Magnoliophyta, are the most diverse group of land plants, with 416 families, approx. 13,164 known genera and a total of c.295,383 known species, etymologically, angiosperm means a plant that produces seeds within an enclosure, in other words, a fruiting plant. The term angiosperm comes from the Greek composite word meaning enclosed seeds, the ancestors of flowering plants diverged from gymnosperms in the Triassic Period, during the range 245 to 202 million years ago, and the first flowering plants are known from 160 mya. They diversified extensively during the Lower Cretaceous, became widespread by 120 mya, angiosperms differ from other seed plants in several ways, described in the table. These distinguishing characteristics taken together have made the angiosperms the most diverse and numerous land plants, the amount and complexity of tissue-formation in flowering plants exceeds that of gymnosperms. The vascular bundles of the stem are arranged such that the xylem and phloem form concentric rings, in the dicotyledons, the bundles in the very young stem are arranged in an open ring, separating a central pith from an outer cortex. In each bundle, separating the xylem and phloem, is a layer of meristem or active formative tissue known as cambium, the soft phloem becomes crushed, but the hard wood persists and forms the bulk of the stem and branches of the woody perennial. Among the monocotyledons, the bundles are more numerous in the stem and are scattered through the ground tissue. They contain no cambium and once formed the stem increases in diameter only in exceptional cases, the characteristic feature of angiosperms is the flower. Flowers show remarkable variation in form and elaboration, and provide the most trustworthy external characteristics for establishing relationships among angiosperm species, the function of the flower is to ensure fertilization of the ovule and development of fruit containing seeds. The floral apparatus may arise terminally on a shoot or from the axil of a leaf, occasionally, as in violets, a flower arises singly in the axil of an ordinary foliage-leaf. There are two kinds of cells produced by flowers. Microspores, which divide to become pollen grains, are the male cells and are borne in the stamens. The female cells called megaspores, which divide to become the egg cell, are contained in the ovule. The flower may consist only of parts, as in willow. Usually, other structures are present and serve to protect the sporophylls, the individual members of these surrounding structures are known as sepals and petals. The outer series is usually green and leaf-like, and functions to protect the rest of the flower, the inner series is, in general, white or brightly colored, and is more delicate in structure. It functions to attract insect or bird pollinators, attraction is effected by color, scent, and nectar, which may be secreted in some part of the flower

Monocotyledon
–
Monocotyledons, commonly referred to as monocots, are flowering plants whose seeds typically contain only one embryonic leaf, or cotyledon. However, molecular research has shown that while the monocots form a monophyletic group or clade. Monocots have almost always recognized as a group, but with various taxonomic ranks. The APG III system of 2009 recognises a clade called monocots, the monocots include about 60,000 species. The largest family in this group by number of species are the orchids, about half as many species belong to the true grasses, which are economically the most important family of monocots. In agriculture the majority of the biomass produced comes from monocots and these include not only major grains, but also forage grasses, sugar cane, and the bamboos. Other economically important monocot crops include various palms, bananas, gingers and their relatives, turmeric and cardamom, asparagus and the onions and garlic family. Additionally most of the bulbs, plants cultivated for their blooms, such as lilies, daffodils, irises, amaryllis, cannas, bluebells. The monocots or monocotyledons have, as the name implies, a single cotyledon, or embryonic leaf, from a diagnostic point of view the number of cotyledons is neither a particularly useful characteristic, nor is it completely reliable. Nevertheless, monocots are sufficiently distinctive that there has rarely been disagreement as to membership of this group, however, morphological features that reliably characterise major clades are rare. Thus monocots are distinguishable from other angiosperms both in terms of their uniformity and diversity, although largely herbaceous, some arboraceous monocots reach great height, length and mass. The latter include agaves, palms, pandans, and bamboos and this creates challenges in water transport that monocots deal with in various ways. Some such as species of Yucca develop anomalous secondary growth, while palm trees, the axis undergoes primary thickening, that progresses from internode to internode, resulting in a typical inverted conical shape of the basal primary axis. The limited conductivity also contributes to limited branching of the stems, despite these limitations a wide variety of adaptive growth forms has resulted from epiphytic orchids and bromeliads to submarine Alismatales and mycotrophic Burmanniaceae and Triuridaceae. Other monocots, particularly Poales have adopted a life form. Leaves The cotyledon, the primordial Angiosperm leaf consists of a proximal leaf base or hypophyll, in moncots the hypophyll tends to be the dominant part in contrast to other angiosperms. Mature monocot leaves are narrow and linear, forming a sheathing around the stem at its base. There is usually only one leaf per node because the leaf base encompasses more than half the circumference, the evolution of this monocot characteristic has been attributed to developmental differences in early zonal differentiation rather than meristem activity

Anigozanthos
–
Anigozanthos is a small genus of Australian plants in the Bloodwort family Haemodoraceae. The 11 species and several subspecies are known as kangaroo paw and catspaw depending on the shape of their flowers. The genus was first named by Jacques Labillardière in his work, Relation du Voyage à la Recherche de la Pérouse, the French botanist collected and described the type species, Anigozanthus rufus, during the dEntrecasteaux expeditions visit to Southwest Australia in 1792. In recent years a number of hybrids and cultivars have been developed. Kangaroo paws are much in demand as house plants and as cut flowers, the red-and-green kangaroo paw is the floral emblem of Western Australia. These perennials are endemic to dry sandy, siliceous areas of southwest Australia and they are grown commercially in Australia, the United States, Japan and Israel. The plant grows from short, underground, horizontal rhizomes, the length and the character of these may vary between the species, some are fleshy, others are fragile. The sap in the system allows the plants to survive extreme dry spells. In summer, a number of species die back to the rhizome, the plants have a basal rosette of long green to greyish-green leaves. The leaves of species are hairy. From the heart of this roset merge long leafless stalks, which can reach 2 m, the size and height of these stalks, which can be clothed in coloured hairs, varies between the species. The tuberous flower buds are covered with coloured hairs, giving it a velvety aspect. These long furry hairs also determine the colour of the flower, the tubular form of the flower bud resembles a kangaroo paw, hence its name. The flower tip spreads fanlike into six petals, full-grown plants can have up to ten flowers at the end of each stalk. The diversity of the genus is classified by 11 species, several of their subspecies are recognised by FloraBase as rare or endangered taxa, Anigozanthos bicolor ssp. bicolor Anigozanthos bicolor ssp. decrescens Anigozanthos bicolor ssp. exstans Anigozanthos bicolor ssp. minor Anigozanthos flavidus DC. Metallica The popularity of Anigozanthos, as a plant or commercially produced cut-flower, has led to the development of cultivars. The Australian Cultivar Registration Authority lists twenty seven registered names and descriptions of cultivars derived from the genus, a larger number of patents for these, accepted or granted varieties, are recorded in the Plant breeders rights database.

Species
–
In biology, a species is the basic unit of biological classification and a taxonomic rank. A species is defined as the largest group of organisms in which two individuals can produce fertile offspring, typically by sexual reproduction. While this definition is often adequate, looked at more closely it is problematic, for example, with hybridisation, in a species complex of hundreds of similar microspecies, or in a ring species, the boundaries between closely related species become unclear. Other ways of defining species include similarity of DNA, morphology, all species are given a two-part name, a binomial. The first part of a binomial is the genus to which the species belongs, the second part is called the specific name or the specific epithet. For example, Boa constrictor is one of four species of the Boa genus, Species were seen from the time of Aristotle until the 18th century as fixed kinds that could be arranged in a hierarchy, the great chain of being. In the 19th century, biologists grasped that species could evolve given sufficient time, Charles Darwins 1859 book The Origin of Species explained how species could arise by natural selection. Genes can sometimes be exchanged between species by horizontal transfer, and species may become extinct for a variety of reasons. In his biology, Aristotle used the term γένος to mean a kind, such as a bird or fish, a kind was distinguished by its attributes, for instance, a bird has feathers, a beak, wings, a hard-shelled egg, and warm blood. A form was distinguished by being shared by all its members, Aristotle believed all kinds and forms to be distinct and unchanging. His approach remained influential until the Renaissance, when observers in the Early Modern period began to develop systems of organization for living things, they placed each kind of animal or plant into a context. Many of these early delineation schemes would now be considered whimsical, animals likewise that differ specifically preserve their distinct species permanently, one species never springs from the seed of another nor vice versa. In the 18th century, the Swedish scientist Carl Linnaeus classified organisms according to shared physical characteristics and he established the idea of a taxonomic hierarchy of classification based upon observable characteristics and intended to reflect natural relationships. At the time, however, it was widely believed that there was no organic connection between species, no matter how similar they appeared. However, whether or not it was supposed to be fixed, by the 19th century, naturalists understood that species could change form over time, and that the history of the planet provided enough time for major changes. Jean-Baptiste Lamarck, in his 1809 Zoological Philosophy, described the transmutation of species, proposing that a species could change over time, in 1859, Charles Darwin and Alfred Russel Wallace provided a compelling account of evolution and the formation of new species. Darwin argued that it was populations that evolved, not individuals and this required a new definition of species. Darwin concluded that species are what appear to be, ideas

Western Australia
–
Western Australia is a state occupying the entire western third of Australia. It is bounded by the Indian Ocean to the north and west, the Great Australian Bight and Southern Ocean to the south, the state has about 2.6 million inhabitants, around 11% of the national total. 92% of the lives in the south-west corner of the state. The first European visitor to Western Australia was the Dutch explorer Dirk Hartog, the first European settlement of Western Australia occurred following the landing by Major Edmund Lockyer on 26 December 1826 of an expedition on behalf of the New South Wales colonial government. This was followed by the establishment of the Swan River Colony in 1829, including the site of the present-day capital, york was the first inland settlement in Western Australia. Situated 97 kilometres east of Perth, it was settled on 16 September 1831, Western Australia achieved responsible government in 1890, and federated with the other British colonies in Australia in 1901. Today its economy relies on mining, agriculture and tourism. The state produces 46% of Australias exports, Western Australia is the second-largest iron ore producer in the world. The International Hydrographic Organization designates the body of water south of the continent as part of the Indian Ocean, the total length of the states eastern border is 1,862 km. There are 20,781 km of coastline, including 7,892 km of island coastline, the total land area occupied by the state is 2.5 million km2. Most of the state is a low plateau with an elevation of about 400 metres, very low relief. This descends relatively sharply to the plains, in some cases forming a sharp escarpment. The extreme age of the landscape has meant that the soils are remarkably infertile, even soils derived from granitic bedrock contain an order of magnitude less available phosphorus and only half as much nitrogen as soils in comparable climates in other continents. Soils derived from extensive sandplains or ironstone are even less fertile, nearly devoid of soluble phosphate and also deficient in zinc, copper, molybdenum, the infertility of most of the soils has required heavy application by farmers of chemical fertilisers, particularly superphosphate, insecticides and herbicides. These have resulted in damage to invertebrate and bacterial populations, the grazing and use of hoofed mammals and, later, heavy machinery through the years have resulted in compaction of soils and great damage to the fragile soils. Large-scale land clearing for agriculture has damaged habitats for native flora, large areas of the states wheatbelt region have problems with dryland salinity and the loss of fresh water. The southwest coastal area has a Mediterranean climate and it was originally heavily forested, including large stands of karri, one of the tallest trees in the world. This agricultural region is one of the nine most bio-diverse terrestrial habitats, thanks to the offshore Leeuwin Current, the area is one of the top six regions for marine biodiversity and contains the most southerly coral reefs in the world

Floral emblem
–
In a number of countries, plants have been chosen as symbols to represent specific geographic areas. Some countries have a floral emblem, others in addition have symbols representing subdivisions. Different processes have been used to adopt these symbols – some are conferred by government bodies, the term floral emblem, which refers to flowers specifically, is primarily used in Australia and Canada. In the United States, the state flower is more often used. The national flower and floral emblem of Bangladesh is the shapla, or Nymphaea nouchali) See also, bhutan – Blue poppy Brunei – Simpoh Ayer Cambodia formally adopted the romduol as its national flower in the year 2005 by a royal decree. The royal decree designates the taxon as Mitrella mesnyi, however this is an illegitimate synonym for Sphaerocoryne affinis Ridley. The flower of India is also the lotus, a symbol of purity that remains immaculate despite growing from mud, keralas state floral emblem is the tree Cassia fistula. Tamil Nadus floral emblem is Glory lily, water-lily is the state flower of Andhra Pradesh. Kapau is the flower of Assam. Bihars floral emblem is kachnaar and that of Uttarakhand is the rhododendron, there are three types of floral emblems that symbolize Indonesia, the puspa bangsa of Indonesia is melati the puspa pesona is anggrek bulan the puspa langka is padma raksasa rafflesia. Melati, a white flower with sweet fragrance, has long been considered as a sacred flower in Indonesian tradition, as it symbolizes purity, sacredness. For example, on her day, a traditional Indonesian brides hair is often adorned with arrangements of jasmine. However, jasmine is also used as floral offering for spirits and deities. Moon Orchid was chosen for its beauty, while the two rare flowers, Rafflesia arnoldii and Titan arum were chosen to demonstrate uniqueness and Indonesian rich biodiversity. Each of the 33 provinces of Indonesia also has a plant as its provincial flower. Iran – red rose, tulip, Nymphaea, Cupressus sempervirens Iraq – Rose The Israeli national flower is the poppy anemone, jordan – Black iris Kuwait – Rhanterium epapposum The national flower is the plumeria, despite it being no longer endemic. The national flower of Malaysia is the bunga raya, the flower of the eastern Malaysian state of Sarawak is the orchid Phalaenopsis bellina, while that of the state of Kedah is the pokok padi. Malaccas state flower is the bread-flower, Vallaris glabra, from there, it spread into France, Italy and the Mediterranean, and eventually it was introduced to the rest of Western Europe and Britain

Rhizome
–
In botany and dendrology, a rhizome is a modified subterranean stem of a plant that is usually found underground, often sending out roots and shoots from its nodes. Rhizomes are also called creeping rootstalks and rootstocks, Rhizomes develop from axillary buds and are diageotropic or grow perpendicular to the force of gravity. The rhizome also retains the ability to new shoots to grow upwards. If a rhizome is separated into pieces, each piece may be able to rise to a new plant. The plant uses the rhizome to store starches, proteins, and these nutrients become useful for the plant when new shoots must be formed or when the plant dies back for the winter. This is a known as vegetative reproduction and is used by farmers and gardeners to propagate certain plants. This also allows for lateral spread of grasses like bamboo and bunch grasses, examples of plants that are propagated this way include hops, asparagus, ginger, irises, Lily of the Valley, cannas, and sympodial orchids. Some rhizomes which are used directly in cooking include ginger, turmeric, galangal, stored rhizomes are subject to bacterial and fungal infections, making them unsuitable for replanting and greatly diminishing stocks. However, rhizomes can also be produced artificially from tissue cultures, the ability to easily grow rhizomes from tissue cultures leads to better stocks for replanting and greater yields. The plant hormones ethylene and jasmonic acid have found to help induce and regulate the growth of rhizomes. Ethylene that was applied externally was found to affect internal ethylene levels, knowledge of how to use these hormones to induce rhizome growth could help farmers and biologists producing plants grown from rhizomes more easily cultivate and grow better plants. The poplars are an example of trees that propagate using a rhizome, the Pando colony in Utah is a famous example, which has been living for about 80,000 years. In general, rhizomes have short internodes, they send out roots from the bottom of the nodes, a stem tuber is a thickened part of a rhizome or stolon that has been enlarged for use as a storage organ. In general, a tuber is high in starch, for example, the common potato, the term tuber is often used imprecisely, and is sometimes applied to plants with rhizomes. Some plants have rhizomes that grow above ground or that lie at the surface, including some Iris species. Rhizomes generally form a layer, but in Giant Horsetails. Many rhizomes have culinary value, and some, such as zheergen, are consumed raw. Aspen Corm Mycorrhiza Media related to Rhizomes at Wikimedia Commons

Perennial plant
–
A perennial plant or simply perennial is a plant that lives for more than two years. The term is used to differentiate a plant from shorter-lived annuals and biennials. The term is widely used to distinguish plants with little or no woody growth from trees and shrubs. Tomato vines, for example, live several years in their natural habitat but are grown as annuals in temperate regions because they dont survive the winter. There is also a class of evergreen, or non-herbaceous, perennials, an intermediate class of plants is known as subshrubs, which retain a vestigial woody structure in winter, e. g. Penstemon. The local climate may dictate whether plants are treated as shrubs or perennials, for instance, many varieties of Fuchsia are shrubs in warm regions, but in colder temperate climates may be cut to the ground every year as a result of winter frosts. The symbol for a plant, based on Species Plantarum by Linnaeus, is. Perennial plants can be short-lived or they can be long-lived, as are some plants like trees. They include an assortment of plant groups from ferns and liverworts to the highly diverse flowering plants like orchids. Plants that flower and fruit only once and then die are termed monocarpic or semelparous, however, most perennials are polycarpic, flowering over many seasons in their lifetime. Perennials typically grow structures that allow them to adapt to living one year to the next through a form of vegetative reproduction rather than seeding. These structures include bulbs, tubers, woody crowns, rhizomes plus others and they might have specialized stems or crowns that allow them to survive periods of dormancy over cold or dry seasons during the year. Many perennials have developed specialized features that allow them to extreme climatic. Some have adapted to hot and dry conditions or cold temperatures. Those plants tend to invest a lot of resource into their adaptations and often do not flower, Many perennials produce relatively large seeds, which can have an advantage, with larger seedlings produced after germination that can better compete with other plants. Some annuals produce many seeds per plant in one season, while some perennials are not under the same pressure to produce large numbers of seeds. In warmer and more favorable climates, perennials grow continuously, in seasonal climates, their growth is limited to the growing season. In some species, perennials retain their foliage all year round, other plants are deciduous perennials, for example, in temperate regions a perennial plant may grow and bloom during the warm part of the year, with the foliage dying back in the winter

Darling Scarp
–
The Darling Scarp, also referred to as the Darling Range or Darling Ranges, is a low escarpment running north-south to the east of the Swan Coastal Plain and Perth, Western Australia. The escarpment extends generally north of Bindoon, to the south of Pemberton, the adjacent Darling Plateau goes easterly to include Mount Bakewell near York and Mount Saddleback near Boddington. It was named after the Governor of New South Wales Lieutenant-General Ralph Darling, the feature was first recorded as General Darling Range by Charles Fraser, Government Botanist with Captain James Stirling aboard HMS Success in March 1827. There is also a tendency to identify the locations on or to the east of the scarp as being in the Perth Hills, the earliest traverses by British settlers in the Swan River Colony occurred in the 1830s. The best known of these is the expedition of Ensign Robert Dale, the Darling Fault is exposed for over 1,000 kilometres, from the area east of Shark Bay, to the southern coast of Western Australia east of Albany. The location of the scarp must once have coincided with the location of the fault, the original location of the scarp is indicated in places by an unusual landform known as the Ridge Hill Shelf. The Darling Plateau is covered by lateritic materials that cover the underlying geology, the Archaean granites and gneisses of the Yilgarn Craton form the high ground of the Perth Hills and can be observed in road cuts, with good examples in the Mundaring Weir area. This area is also a distinct section of the larger Yilgarn Block province. Often the Bureau of Meteorology identifies different weather for the hills in comparison to that of the Swan Coastal Plain. Also, in hot summers, strong easterly winds travelling across the scarp have presented serious issues for planes using the Perth Airport because of the alignment of the runways. A documented accident in 1999 involving wind shear from the scarp is at the Perth Airport article, in addition, orographic uplift is produced when rain clouds move over the hills, giving higher rainfalls in settlements in the ranges compared with their coastal neighbours. The Darling escarpment has been exploited for stone quarries, forestry, extensive timber railways and timber mills and the supporting communities existed along the escarpment because of the high quality jarrah forests. In the early century, most of the main rivers flowing off the escarpment had mainly been used for dams for water supply for metropolitan Perth. The scarp also defines the easternmost limit of the various aquifers present in the Perth Basin sediments, the scarp forms a divide between the hypersaline groundwaters typical of the Yilgarn Craton basement from the fresh ground waters of the Perth Basin. Some dams along the scarp are contaminated by seepage of water from the granite into the base of the dams water column. Also in the early to mid-twentieth century numerous rock quarries existed on the edge of the escarpment - visible and affecting both the aesthetics and the environment of the escarpment. In the area where the Helena River emerges from its valley to the sandplain, there are still four quarries evident, mountain and Stathams quarries are now managed as rock climbing locations. Bluestone quarry, later known as Greenmount Quarry, at Greenmount Hill on the west side of Greenmount National Park, mountain Quarry, south of Greenmount Hill, which ceased operation in 1963

Perth
–
Perth is the capital and largest city of the Australian state of Western Australia. It is the fourth-most populous city in Australia, with a population of 2.06 million living in Greater Perth. The first areas settled were on the Swan River, with the central business district. Perth was founded by Captain James Stirling in 1829 as the centre of the Swan River Colony. It gained city status in 1856, and was promoted to the status of a Lord Mayorality in 1929. The city is named after Perth, Scotland, due to the influence of Sir George Murray, Member of Parliament for Perthshire and Secretary of State for War and the Colonies. The citys population increased substantially as a result of the Western Australian gold rushes in the late 19th century, largely as a result of emigration from the eastern colonies of Australia. During Australias involvement in World War II, Fremantle served as a base for operating in the Pacific Theatre. An influx of immigrants after the war, predominantly from Britain, Greece, Italy and Yugoslavia, Aboriginal people have inhabited the Perth area for 38,000 years, as evidenced by archaeological remains at Upper Swan. The Noongar people occupied the southwest corner of Western Australia and lived as hunter-gatherers, the wetlands on the Swan Coastal Plain were particularly important to them, both spiritually and as a source of food. The Noongar people know the area where Perth now stands as Boorloo, Boorloo formed part of Mooro, the tribal lands of Yellagongas group, one of several based around the Swan River and known collectively as the Whadjuk. The Whadjuk were part of a group of fourteen tribes that formed the south-west socio-linguistic block known as the Noongar. The judgment was overturned on appeal, the first documented sighting of the region was made by the Dutch Captain Willem de Vlamingh and his crew on 10 January 1697. The British colony would be officially designated Western Australia in 1832, Captain James Stirling, aboard Parmelia, said that Perth was as beautiful as anything of this kind I had ever witnessed. On 12 August that year, Helen Dance, wife of the captain of the ship, Sulphur. The only contemporary information on the source of the name comes from Fremantles diary entry for 12 August, Murray was born in Perth, Scotland, and was in 1829 Secretary of State for the Colonies and Member for Perthshire in the British House of Commons. The town was named after the Scottish Perth, in Murrays honour, the racial relations between the Noongar people and the Europeans were strained due to these happenings. Because of the amount of building in and around Boorloo
