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

Eucalyptus
–
Eucalyptus /ˌjuːkəˈlɪptəs/ LHeritier 1789 is a diverse genus of flowering trees and shrubs in the myrtle family, Myrtaceae. Members of the genus dominate the flora of Australia. There are more than 700 species of eucalyptus and most are native to Australia, one species, Eucalyptus deglupta, ranges as far north as the Philippines. Of the 15 species found outside Australia, just nine are exclusively non-Australian, species of eucalyptus are cultivated widely in the tropical and temperate world, including the Americas, Europe, Africa, the Mediterranean Basin, the Middle East, China, and the Indian subcontinent. However, the range over which many eucalypts can be planted in the zone is constrained by their limited cold tolerance. Australia is covered by 92,000,000 hectares of eucalypt forest, Eucalyptus is one of three similar genera that are commonly referred to as eucalypts, the others being Corymbia and Angophora. Many species, though by no means all, are known as gum trees because they exude copious kino from any break in the bark. The generic name is derived from the Greek words ευ well and καλύπτω to cover, Eucalyptus oil finds many uses like in aromatherapy, as a cure for joint pains. Eucalyptus trees show allelopathic effects, they release compounds which inhibit other plant species from growing nearby, on warm days, eucalyptus forests are sometimes shrouded in a smog-like mist of vaporised volatile organic compounds, the Australian Blue Mountains take their name from the haze. A mature eucalyptus may take the form of a low shrub or a large tree. The species can be divided into three main habits and four size categories, as a generalisation forest trees are single-stemmed and have a crown forming a minor proportion of the whole tree height. Woodland trees are single-stemmed, although they may branch at a distance above ground level. Many mallee trees may be so low-growing as to be considered a shrub, two other tree forms are notable in Western Australia and described using the native names mallet and marlock. The mallet is a small to medium-sized tree that does not produce lignotubers and has a long trunk. This is the habit of mature healthy specimens of Eucalyptus occidentalis, E. astringens, E. spathulata, E. gardneri, E. dielsii, E. forrestiana, E. salubris, E. clivicola. The smooth bark of mallets often has a satiny sheen and may be white, cream, grey, green, or copper. The term marlock has been used, in Forest Trees of Australia, it is defined as a small tree without lignotubers. They usually grow in more or less pure stands, clearly recognisable examples are stands of E. platypus, E. vesiculosa, and the unrelated E. stoatei

Glossary of leaf morphology
–
The following is a defined list of terms which are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple or compound, the edge of the leaf may be regular or irregular, may be smooth or bearing hair, bristles or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article, leaves of most plants include a flat structure called the blade or lamina, but not all leaves are flat, some are cylindrical. Leaves may be simple, with a leaf blade, or compound. In flowering plants, as well as the blade of the leaf, there may be a petiole and stipules, leaf structure is described by several terms that include, Being one of the more visible features, leaf shape is commonly used for plant identification. Edge and margin are both interchangeable in the sense that they refer to the perimeter of a leaf. Leaves may also be folded or rolled in various ways, the folding of leaves within a bud is vernation, ptyxis is the folding of an individual leaf in a bud

Victoria (Australia)
–
Victoria is a state in southeast Australia. Victoria is Australias most densely populated state and its second-most populous state overall, most of its population is concentrated in the area surrounding Port Phillip Bay, which includes the metropolitan area of its state capital and largest city, Melbourne, Australias second-largest city. Prior to British European settlement, the area now constituting Victoria was inhabited by a number of Aboriginal peoples. With Great Britain having claimed the entire Australian continent east of the 135th meridian east in 1788, Victoria was included in the wider colony of New South Wales. The first settlement in the area occurred in 1803 at Sullivan Bay, and much of what is now Victoria was included in the Port Phillip District in 1836, Victoria was officially created as a separate colony in 1851, and achieved self-government in 1855. Politically, Victoria has 37 seats in the Australian House of Representatives and 12 seats in the Australian Senate, at state level, the Parliament of Victoria consists of the Legislative Assembly and the Legislative Council. Victoria is currently governed by the Labor Party, with Daniel Andrews the current Premier, the personal representative of the Queen of Australia in the state is the Governor of Victoria, currently Linda Dessau. Local government is concentrated in 79 municipal districts, including 33 cities, although a number of unincorporated areas still exist, Victorias total gross state product is ranked second in Australia, although Victoria is ranked fourth in terms of GSP per capita because of its limited mining activity. Culturally, Melbourne is home to a number of museums, art galleries and theatres and is described as the sporting capital of Australia. The Melbourne Cricket Ground is the largest stadium in Australia, and the host of the 1956 Summer Olympics, Victoria has eight public universities, with the oldest, the University of Melbourne, having been founded in 1853. Victoria, like Queensland, was named after Queen Victoria, who had been on the British throne for 14 years when the colony was established in 1851. The first British settlement in the later known as Victoria was established in October 1803 under Lieutenant-Governor David Collins at Sullivan Bay on Port Phillip. In the year 1826 Colonel Stewart, Captain S. Wright, fly and the brigs Dragon and Amity, took a number of convicts and a small force composed of detachments of the 3rd and 93rd regiments. Victorias next settlement was at Portland, on the south west coast of what is now Victoria, edward Henty settled Portland Bay in 1834. Melbourne was founded in 1835 by John Batman, who set up a base in Indented Head, from settlement the region around Melbourne was known as the Port Phillip District, a separately administered part of New South Wales. Shortly after the now known as Geelong was surveyed by Assistant Surveyor W. H. Smythe. And in 1838 Geelong was officially declared a town, despite earlier white settlements dating back to 1826, days later, still in 1851 gold was discovered near Ballarat, and subsequently at Bendigo. Later discoveries occurred at sites across Victoria

New South Wales
–
New South Wales is a state on the east coast of Australia. It borders Queensland to the north, Victoria to the south and it has a coast line with the Tasman Sea on its east side. The Australian Capital Territory is an enclave within the state, New South Wales state capital is Sydney, which is also Australias most populous city. In March 2014, the population of New South Wales was 7.5 million. Just under two-thirds of the population,4.67 million. Inhabitants of New South Wales are referred to as New South Welshmen, the Colony of New South Wales was founded as a penal colony in 1788. It originally comprised a more than half of the Australian mainland with its western boundary set at 129th meridian east in 1825, in addition, the colony also included the island territories of New Zealand, Van Diemens Land, Lord Howe Island, and Norfolk Island. During the 19th century, most of the area was detached to form separate British colonies that eventually became New Zealand. However, the Swan River Colony has never administered as part of New South Wales. Lord Howe Island remains part of New South Wales, while Norfolk Island has become a federal Territory, as have the now known as the Australian Capital Territory. The prior inhabitants of New South Wales were the Aboriginal tribes who arrived in Australia about 40,000 to 60,000 years ago, before European settlement there were an estimated 250,000 Aboriginal people in the region. The Wodi Wodi people are the custodians of the Illawarra region of South Sydney. The Bundjalung people are the custodians of parts of the northern coastal areas. The European discovery of New South Wales was made by Captain James Cook during his 1770 survey along the eastern coast of the Dutch-named continent of New Holland. In his original journal covering the survey, in triplicate to satisfy Admiralty Orders, Cook first named the land New Wales, however, in the copy held by the Admiralty, he revised the wording to New South Wales. After years of chaos and anarchy after the overthrow of Governor William Bligh, macquaries legacy is still evident today. During the 19th century, large areas were separated to form the British colonies of Tasmania, South Australia, Victoria. Responsible government was granted to the New South Wales colony in 1855, following the Treaty of Waitangi, William Hobson declared British sovereignty over New Zealand in 1840

Queensland
–
Queensland is the second-largest and third-most-populous state in the Commonwealth of Australia. Situated in the north-east of the country, it is bordered by the Northern Territory, South Australia and New South Wales to the west, south-west, to the east, Queensland is bordered by the Coral Sea and Pacific Ocean. Queensland has a population of 4,750,500, concentrated along the coast, the state is the worlds sixth largest sub-national entity, with an area of 1,852,642 km2. The capital and largest city in the state is Brisbane, Australias third largest city, often referred to as the Sunshine State, Queensland is home to 10 of Australias 30 largest cities and is the nations third largest economy. Tourism in the state, fuelled largely by its tropical climate, is a major industry. Queensland was first inhabited by Aboriginal Australians and Torres Strait Islanders, the first European to land in Queensland was Dutch navigator Willem Janszoon in 1606, who explored the west coast of the Cape York Peninsula near present-day Weipa. In 1770, Lieutenant James Cook claimed the east coast of Australia for the Kingdom of Great Britain. The colony of New South Wales was founded in 1788 by Governor Arthur Phillip at Sydney, New South Wales at that time included all of what is now Queensland, Queensland was explored in subsequent decades until the establishment of a penal colony at Brisbane in 1824 by John Oxley. Penal transportation ceased in 1839 and free settlement was allowed from 1842, the state was named in honour of Queen Victoria, who on 6 June 1859 signed Letters Patent separating the colony from New South Wales. The 6th of June is now celebrated statewide as Queensland Day. Queensland achieved statehood with the Federation of Australia on 1 January 1901, the history of Queensland spans thousands of years, encompassing both a lengthy indigenous presence, as well as the eventful times of post-European settlement. The north-eastern Australian region was explored by Dutch, Spanish and French navigators before being encountered by Lieutenant James Cook in 1770, the Australian Labor Party has its origin as a formal organisation in Queensland and the town of Barcaldine is the symbolic birthplace of the party. June 2009 marked the 150th anniversary of its creation as a colony from New South Wales. The Aboriginal occupation of Queensland is thought to predate 50,000 BC, likely via boat or land bridge across Torres Strait, during the last ice age Queenslands landscape became more arid and largely desolate, making food and other supplies scarce. This led to the worlds first seed-grinding technology, warming again made the land hospitable, which brought high rainfall along the eastern coast, stimulating the growth of the states tropical rainforests. In February 1606, Dutch navigator Willem Janszoon landed near the site of what is now Weipa and this was the first recorded landing of a European in Australia, and it also marked the first reported contact between European and Aboriginal Australian people. The region was explored by French and Spanish explorers prior to the arrival of Lieutenant James Cook in 1770. Cook claimed the east coast under instruction from King George III of the United Kingdom on 22 August 1770 at Possession Island, naming Eastern Australia, including Queensland, the Aboriginal population declined significantly after a smallpox epidemic during the late 18th century

Eucalyptus crebra
–
Eucalyptus crebra, commonly known as the narrow-leaved ironbark or narrowleaf red ironbark, is a type of Ironbark tree native to eastern Australia. A member of the large genus Eucalyptus, this tree is in the Myrtaceae family and it is an important source of nectar in the honey industry and its hard, strong timber is used in construction. The Narrow-leaved ironbark was originally described by Victoria state botanist Ferdinand von Mueller in 1859, the specific epithet is the Latin adjective crebra crowded or close together. Within the genus Eucalyptus, it belongs in the subgenus Symphyomyrtus and this plant is a large spreading tree, which may reach 35 m in height. The rough furrowed bark is mottled with yellow and orange. The trees name ironbark stems from the rough and unyielding texture of the cambium on the outmost layer of the plant, in the early days of colonization wood felling was achieved with axe and saw, ironbark stands usually meant a broken ax head. The narrow lanceolate leaves are a uniform greyish-green in colour and measure 7–15 cm in length by 0. 9–1.7 cm wide, the small white flowers appear from late autumn to spring, and are followed by small pods. The Narrow-leaved ironbark is found in eastern Australia, from Picton southwest of Sydney north through New South Wales, the narrow-leaved ironbark is one of the key canopy species of the threatened Cumberland Plain Woodlands. Koalas can consume the leaves, and the flowers are pollinated mainly by insects, the southern or shady side of the trunk is habitat for lichens. The tree has a hard, strong, and dark red timber, a plank has been recorded as being used for Elizabeth Farm, Australias oldest surviving European dwelling. It is used as a tree or to line roadways. It is useful in production as the flowers are heavy in nectar and pollen

Brachychiton populneus
–
The extended trunk is a water storage device for survival in a warm dry climate. The bell-shaped flowers are variable in colour while the leaves vary considerably in shape, the leaves are either simple and pointed, or may be 3 -9 lobed. Saplings grow from a drought and fire resistant tap-rooted tuber, seeds are eaten by Aboriginal people after roasting. The soft spongy wood was used for making shields, and the bark as a fibre, the leaves are also used as emergency fodder for drought-affected animal stock. It has been introduced as a tree to south-western Australia, South Africa, Louisiana, California, Arizona. In Western Australia it was observed to be invasive in disturbed areas, horticulturists have hybridised the Kurrajong with related Brachychiton species, including the Queensland bottle tree and Illawarra Flame Tree to produce new garden ornamentals. The specific name pertains to a perceived similarity to genus Populus. Sometimes B. populneus is also known by the names lacebark kurrajong, however, B. discolor is also referred to as the Lacebark Kurrajong, and Bottle Tree is a term commonly applied not only to other species of Brachychiton but to members of other genera around the world. The kurrajong has been recorded as a host plant for the mistletoe species Dendrophthoe glabrescens

Wagga Wagga
–
Wagga Wagga is a major regional city in the Riverina region of New South Wales, Australia. The central business district is focused around the commercial and recreational grid bounded by Best and Tarcutta Streets and the Murrumbidgee River, the main shopping street of Wagga is Baylis Street which becomes Fitzmaurice Street at the northern end. The city is in a valley and much of the city has a problem with urban salinity. The original inhabitants of the Wagga Wagga region were the Wiradjuri people, in 1829, Charles Sturt became the first European explorer to visit the future site of the city. The town, positioned on the site of a ford across the Murrumbidgee, was surveyed and gazetted as a village in 1849, in 1870, the town was gazetted as a municipality. During the negotiations leading to the federation of the Australian colonies, during World War I the town was the starting point for the Kangaroo recruitment march. The Great Depression and the resulting hardship saw Wagga Wagga become the centre of a movement for the Riverina region. Wagga Wagga became a town during World War II with the establishment of a military base at Kapooka and Royal Australian Air Force bases at Forest Hill. After the war, Wagga Wagga was proclaimed as a city in 1946, in 1982 the city was amalgamated with the neighbouring Kyeamba and Mitchell Shires to form the City of Wagga Wagga local government area. Wagga Wagga is at the end of the Riverina region where the slopes of the Great Dividing Range flatten. The city straddles the Murrumbidgee River, one of the rivers of the Murray-Darling Basin. This location astride some of the transport routes in the nation has made Wagga Wagga an important heavy truck depot for a number of companies including Toll Holdings. Wagga Wagga is upstream from the Riverina plain in the mid-catchment range of the Murrumbidgee River in an alluvial valley confined by low bedrock hills, much of Wagga Wagga is on heavy clay soils in a large drainage basin with a small catchment discharge point. Groundwater therefore cannot leave easily, leading to Wagga Wagga having a problem with waterlogged soil and soil salination, urban salination in Wagga Wagga is now the subject of a large multi-pronged approach to prevent further salination and reclaim salt-affected areas. The main shopping street of Wagga Wagga is Baylis Street which becomes Fitzmaurice Street at the northern end, the Wollundry Lagoon is the water focus of the city centre and has been a key element in the development and separation of the north and south parts of the city centre. Major industrial areas of Wagga Wagga include the suburb of Bomen. Thomas Mitchell, the surveyor who served under Lord Wellington named many of the streets after Peninsula War veterans, Wagga Wagga has a temperate climate with hot dry summers and cool to cold winters. Under the Köppen climate classification, the city has a subtropical climate

Allan Cunningham (botanist)
–
Allan Cunningham was an English botanist and explorer, primarily known for his travels in Australia to collect plants. Cunningham was born in Wimbledon, Surrey, the son of Allan Cunningham, who came from Renfrewshire, Scotland, Allan Cunningham was educated at a Putney private school, Reverend John Adams Academy and then went into a solicitors office. He afterwards obtained a position with William Townsend Aiton superintendent of Kew Gardens, on Banks recommendation, Cunningham went to Brazil with James Bowie between 1814 and 1816 collecting specimens for Kew Gardens. On 28 September 1816 he sailed for Sydney where he arrived on 20 December 1816, among other explorations, he joined John Oxleys 1817 expedition beyond the Blue Mountains to the Lachlan and Macquarie rivers and shared in the privations of the 1,200 miles journey. He was able to collect specimens of about 450 species and gained experience as an explorer. Cunningham traveled as the ships botanist aboard HMS Mermaid under Phillip Parker King from 1817 to 1820, the Mermaid was of only 85 tons, but sailing on 22 December 1817 they reached King George Sound on 21 January 1818. Though their stay was short many specimens were found but the islands on the west coast were comparatively barren, towards the end of March the Goulburn Islands on the north coast were reached and many new plants were discovered. They reached Timor on 4 June 1818 and, turning for home, Cunninghams collections during this voyage included about 300 species. Shortly after his return, Cunningham made an excursion south from Sydney, ascending the prominent peak of Mount Keira overlooking the Illawarra region, towards the end of the year he made a voyage to Tasmania arriving at Hobart on 2 January 1819. He next visited Launceston and though often finding the botany interesting, he found little that was absolutely new, in May he went with King in the Mermaid on a second voyage to the north and north-west coasts. On this occasion they started up the east coast and Cunningham found many opportunities for adding to his collections, one of these was after the ship reached the mouth of the Endeavour River on 28 June 1819. The circumnavigation of Australia was completed on 27 August when they reached Vernon Island in Clarence Strait and they again visited Timor and arrived back in Sydney on 12 January 1820. The third voyage to the north coast with King began on 15 June, but meeting bad weather the bowsprit was lost, sailing again on 13 July 1820 the northerly course was followed and eventually the continent was circumnavigated. The Mermaid was then condemned and the voyage was on the Bathurst which was twice the size of the Mermaid. They left on 26 May 1821, the route was chosen, and when they were on the west coast of Australia it was found necessary to go to Mauritius to refit. They left after a stay of seven weeks and reached King George Sound on 24 December 1821. A sufficiently long stay was made for Cunningham to make an excellent collection of plants, Sydney was reached again on 25 April 1822. Cunningham provided a chapter on botany to Kings Narrative of a Survey, in September 1822 Cunningham went on an expedition over the Blue Mountains and arrived at Bathurst on 14 October 1822 and returned to Parramatta in January 1823
