105-493: The waratah ( Telopea ) is an Australian -endemic genus of five species of large shrubs or small trees, native to the southeastern parts of Australia ( New South Wales , Victoria , and Tasmania ). The best-known species in this genus is Telopea speciosissima , which has bright red flowers and is the New South Wales (NSW) state emblem. The waratah is a member of the family Proteaceae , flowering plants distributed in

210-479: A Mediterranean climate . The south-east ranges from oceanic (Tasmania and coastal Victoria) to humid subtropical (upper half of New South Wales), with the highlands featuring alpine and subpolar oceanic climates . The interior is arid to semi-arid . Driven by climate change , average temperatures have risen more than 1°C since 1960 . Associated changes in rainfall patterns and climate extremes exacerbate existing issues such as drought and bushfires . 2019

315-525: A belt of Brigalow grasslands lie between the coast and the mountains, while inland of the dividing range are large areas of grassland and shrubland. These include the western plains of New South Wales, and the Mitchell Grass Downs and Mulga Lands of inland Queensland. The northernmost point of the mainland is the tropical Cape York Peninsula . The landscapes of the Top End and

420-824: A large wave of immigration from across Europe , with such immigrants referred to as " New Australians ". This required a relaxation of the white Australia policy , which was justified to Australians using the slogan "populate or perish". A member of the Western Bloc during the Cold War , Australia participated in the Korean War and the Malayan Emergency during the 1950s and the Vietnam War from 1962 to 1972. During this time, tensions over communist influence in society led to unsuccessful attempts by

525-509: A 4–6 week period in spring (September–October) in the Sydney region, but later in cooler areas. Indigenous Tharawal peoples from around the Cronulla region of southern Sydney use the waratah medicinally. Placing the flowers into a bowl of water so that the nectar can be soaked out, the flower water is then drunk for pleasure (for its strengthening effect and for curing illnesses in children and

630-547: A 6–8 week period after primary flush growth from November to January. After the primordia initiation there may be another vegetative flush of growth on the plants. The flower develops in bud form for seven to eight months. The date of flowering is highly variable as waratah flowering is sensitive to its environment. Flowering tends to vary with geographic location and climatic differences, occurring from early August in coastal Queensland and up to December in Tasmania. Waratahs have

735-406: A basal ring of coloured bracts. Before a flower can be produced the plant must undergo floral induction and initiation. Floral induction involves physiological processes in the plant that result in the shoot apical meristem becoming competent to develop flowers. It involves biochemical changes at the apex, particularly those caused by cytokinins and the processes can be reversed. Floral initiation

840-410: A common plant condition known as damping off . Damping off is a condition that causes the death of seeds or seedlings facilitated by a number of different fungal pathogens. A given seed can become infected with a fungus, often causing it to darken and soften, killing the seedling before it emerges or causing it to emerge in a pre-weakened state. Seedlings can also be infected after emergence resulting in

945-468: A compact head or spike. The individual flowers within the inflorescence also give Proteaceae species a unique look. Telopea species are long-lived, perennial plants that re-sprout from lignotubers after fire. After a few years of fire, re-sprouting stems produce the terminal flowers which continue the flowering cycle annually. The Telopea 'flower' is in fact an inflorescence that comprises from as few as 10 to as many as 240 individual flowers, depending upon

1050-461: A date which later became Australia's national day . Most early settlers were convicts , transported for petty crimes and assigned as labourers or servants to "free settlers" (willing immigrants). Once emancipated , convicts tended to integrate into colonial society. Convict rebellions and uprisings were suppressed under martial law, which lasted for two years following the 1808 Rum Rebellion , Australia's only successful coup d'état . During

1155-435: A maximum of sun exposure. A combination of northerly, easterly and westerly aspects will spread the flowering time with the western slope flowering slightly later on. As the location approaches the equator, flowering time will be earlier. Elevation also has to be considered as it will affect temperature, a major influence on flowering time. More flowers will be produced in full sunlight although better quality flowers are found in

1260-477: A reliable crop and a quality bloom. In the wild the waratah has become adapted to growing in nutrient-poor soils leading many people to believe that this is what is necessary for the development of the plant. Fertilisers are not necessary for the development of the plant but the waratah has been shown to be receptive to some treatments. Many native plants have been known to have poor establishment in soils with high levels of nitrogen and phosphorus. This coincides with

1365-581: A settlement was established in Van Diemen's Land (present-day Tasmania ), and in 1813, Gregory Blaxland , William Lawson and William Wentworth crossed the Blue Mountains west of Sydney, opening the interior to European settlement. The British claim extended to the whole Australian continent in 1827 when Major Edmund Lockyer established a settlement on King George Sound (modern-day Albany ). The Swan River Colony (present-day Perth )

1470-562: A short distance off the north-east coast and extends for more than 2,000 km (1,200 mi). Mount Augustus , claimed to be the world's largest monolith, is located in Western Australia. At 2,228 m (7,310 ft), Mount Kosciuszko is the highest mountain on the Australian mainland. Even taller are Mawson Peak , at 2,745 m (9,006 ft), on the remote Australian external territory of Heard Island , and, in

1575-434: A short flowering period in one location, although varieties can be selected to ensure a reasonable spread. It has been shown that in a population of 1000 seedlings where the total flowering time was five weeks, the spread was so that 10% flowered in week one and 10% in week five. Much variation was accounted for by varietal differences with plants of the one variety flowering at much the same time. Generally, waratahs flower over

1680-411: A wide variety of landscapes, with tropical rainforests in the north-east, mountain ranges in the south-east, south-west and east, and desert in the centre. The desert or semi-arid land commonly known as the outback makes up by far the largest portion of land. Australia is the driest inhabited continent; its annual rainfall averaged over continental area is less than 500 mm. The population density

1785-436: Is 3.4 inhabitants per square kilometre, although the large majority of the population lives along the temperate south-eastern coastline. The population density exceeds 19,500 inhabitants per square kilometre in central Melbourne. In 2021 Australia had 10% of the global permanent meadows and pastureland. Forest cover is around 17% of Australia's total land area. The Great Barrier Reef , the world's largest coral reef, lies

1890-413: Is a constitutional monarchy , a parliamentary democracy and a federation . The country has maintained its mostly unchanged constitution alongside a stable liberal democratic political system since Federation in 1901. It is one of the world's oldest federations, in which power is divided between the federal and state governments. The Australian system of government combines elements derived from

1995-417: Is a megadiverse country , and its size gives it a wide variety of landscapes and climates including deserts in the interior and tropical rainforests along the coast . The ancestors of Aboriginal Australians began arriving from south-east Asia 50,000 to 65,000 years ago, during the last glacial period . By the time of British settlement, Aboriginal Australians spoke 250 distinct languages and had

2100-529: Is a country comprising the mainland of the Australian continent , the island of Tasmania and numerous smaller islands . Australia has a total area of 7,688,287 km (2,968,464 sq mi), making it the sixth-largest country in the world and the largest country by area in Oceania . It is the world's oldest, flattest, and driest inhabited continent, with some of the least fertile soils. It

2205-601: Is also the name of the Sydney Trains A set , a class of electric multiple unit trains operated by Sydney Trains in Sydney. In 2009, the Premier of New South Wales, Nathan Rees , commissioned a state logo based on the floral emblem. The resultant logo design has been criticised as resembling a lotus rather than the New South Wales waratah. Australia Australia , officially the Commonwealth of Australia ,

2310-399: Is applied, drainage properties of the soil mean that nutrients are quickly leached and so the best application method is multiple applications at critical stages in development such as flush periods. Pruning is a very important consideration for the commercial growth of waratahs in the effort to design a shape for the plant that will encourage the maximum production of saleable blooms. The aim

2415-436: Is caused by the larvae and damage generally first shows at a branch fork or leaf. The condition is generally confined to young shrubs or trees. The leaves are skeletonised and the larvae web them together into a shelter that incorporates larval faeces. Larvae can also burrow into the developing flower head, obliterating a crop entirely if left uncontrolled. Biological control methods include encouragement of bird species. The borer

2520-426: Is complex though as different clones require different optimal culture conditions requiring different developmental work for each clone. There also exists problems with hardening off, with roots and leaves produced in vivo dying off on planting out. For Telopea plants propagated from seed, the transition from seedling to flower takes about 5 years. Cuttings may take only 2 years. The most common form of propagation

2625-516: Is from seed, however, certain varieties and cultivars must be propagated from cuttings if the grower wishes the plants to remain true to form. Fresh seed has a higher viability than cuttings and will germinate 2–3 weeks after sewing. The overall cultivation of the waratah as a single process is a tricky one as flowering time, number and quality are easily affected by changes in the plant environment. These factors must be considered as early as prior to buying land for production. North facing aspect ensures

2730-586: Is now Southeast Asia. It is uncertain how many waves of immigration may have contributed to these ancestors of modern Aboriginal Australians. The Madjedbebe rock shelter in Arnhem Land is possibly the oldest site showing the presence of humans in Australia. The oldest human remains found are the Lake Mungo remains , which have been dated to around 41,000 years ago. Aboriginal Australian culture

2835-571: Is one of only two pristine Archaean 3.6–2.7 Ga (billion years ago) crusts identified on the Earth. Having been part of all major supercontinents , the Australian continent began to form after the breakup of Gondwana in the Permian , with the separation of the continental landmass from the African continent and Indian subcontinent. It separated from Antarctica over a prolonged period beginning in

2940-466: Is one of the oldest continuous cultures on Earth. At the time of first European contact, Aboriginal Australians belonged to wide range of societies, with diverse economies spread across at least 250 different language groups . Estimates of the Aboriginal population before British settlement range from 300,000 to 3 million. Aboriginal Australians cultures were (and remain) deeply connected with

3045-445: Is present throughout the year and so pesticide treatments with a strong persistent spray should be carried out monthly. What is used for the borer should also control lesser pests such as white scale , which is common in the natural state, and Macadamia leafminer ( Acocercops chionosema ). Leafminer poses no threat to the life of the plant but it is preferred that stems for the market still have leaves attached. Thus damaged leaves lower

3150-496: Is relatively easy in comparison to other stages of the growth cycle. Plants are usually propagated from cuttings, fresh seed or stored seed. Fresh seed has a good germination rate but deteriorates fairly rapidly unless stored at low temperature and low humidity. Dry seed will last a few years in refrigerated storage but should be treated with a general purpose fungicide prior to storage and at propagation to ensure good germination rates and healthy seedlings. The best time to take cuttings

3255-460: Is removed. This means that weed presence during cultivation has a profound effect on growth, particularly when the waratahs are small. Weeds should be seriously tended to in the early stages of growth. Once plants have reached waist height cases should be analysed individually to determine the best method of weed control. In New South Wales the most destructive pest to waratah crops is the macadamia twig girdler ( Neodrepta luteotactella ). The damage

3360-659: Is short, unpredictable and unreliable. Early issues with cultivation meant that approximately 90% of all waratahs sold at Sydney’s Flemington markets in the early 90s were bush picked. Some progress has been made in the 20 years since then with several cultivars being commercially grown mostly in areas to the North and South of Sydney and in the Dandenong Ranges in Victoria. Issues with cultivation are still present however. The propagation of waratah for commercial production

3465-431: Is the morphological transformation of an induced growing point from a vegetative to a floral primordium and involves the plant hormone florigen. Florigen is produced in the leaves in reproductively favourable conditions and acts in buds and growing tips to induce a number of different physiological and morphological changes. Once this process begins, in most plants, it cannot be reversed and the stems develop flowers, even if

3570-455: Is to get as many growing tips as possible as it is on these that the flowers will develop. With the correct mix of factors for cultivation it is possible to produce up to sixty blooms per plant per year. This could translate to up to 20,000 to 50,000 blooms per ha. Waratah inflorescences are harvested when 0–50% of flowers are open, although inflorescences with 0–5% of flower open have the longest vase life and least opportunity for bract damage in

3675-411: Is unique. About 85% of flowering plants, 84% of mammals, more than 45% of birds , and 89% of in-shore, temperate-zone fish are endemic . Australia has at least 755 species of reptile, more than any other country in the world. Besides Antarctica, Australia is the only continent that developed without feline species. Feral cats may have been introduced in the 17th century by Dutch shipwrecks, and later in

3780-423: Is usually a result of sun damage but can also be associated with wind burn. The addition of shade cloths to crop management strategies has been shown to reduce levels of excessive light and has significantly minimised financial losses due to the reduction of occurrence of bract browning. In the natural state, the waratah does not compete very well with surrounding shrubs and is at its best after fire when competition

3885-445: Is when the plant is experiencing a flush of growth. The cuttings are taken from firm wood from the last twelve months growth. If plant material is scarce, single nodes can be used for cutting propagation. Other methods of propagation that are successful but not widely used for commercial production include grafting and tissue culture. Stock for grafting is vigorous and as such is labour-intensive in constant control of stock regrowth from

3990-768: The Colonial Office that it be formally adopted. In 1824, the Admiralty agreed that the continent should be known officially by that name. The first official published use of the new name came with the publication in 1830 of The Australia Directory by the Hydrographic Office . Colloquial names for Australia include " Oz ", " Straya " and " Down Under ". Other epithets include "the Great Southern Land", "the Lucky Country" (from

In 1914, Australia joined the Allies in fighting the First World War, and took part in many of the major battles fought on the Western Front . Of about 416,000 who served, about 60,000 were killed and another 152,000 were wounded. Many Australians regard the defeat of the Australian and New Zealand Army Corps (ANZAC) at Gallipoli in 1915 as

Since 1951, Australia has been allied with the United States under the ANZUS treaty. In the decades following World War II, Australia enjoyed significant increases in living standards, leisure time and suburban development. Governments encouraged

5145-426: The emu and the kookaburra . Australia is home to many dangerous animals including some of the most venomous snakes in the world. The dingo was introduced by Austronesian people who traded with Indigenous Australians around 3000 BCE . Many animal and plant species became extinct soon after first human settlement, including the Australian megafauna ; others have disappeared since European settlement, among them

This continued a process of increasing autonomy from the United Kingdom, highlighted by the Statute of Westminster Adoption Act 1942 , and culminating in the Australia Acts of 1986. Australia is a federal parliamentary democracy and constitutional monarchy comprising six states and ten territories . Its population of more than 28 million is highly urbanised and heavily concentrated on

In Australia these areas include south-west Western Australia, the Queensland coast and also Toowoomba. Overseas, New Zealand, the USA, South Africa, and Israel are all also able to grow waratah with varying degrees of success. It was introduced to England in 1789 but cannot survive English winters out of doors except in

6300-709: The Southern Hemisphere since ancient times. Several 16th-century cartographers used the word Australia on maps, but not to identify modern Australia. When Europeans began visiting and mapping Australia in the 17th century, the name Terra Australis was applied to the new territories. Until the early 19th century, Australia was best known as New Holland , a name first applied by the Dutch explorer Abel Tasman in 1644 (as Nieuw-Holland ) and subsequently anglicised. Terra Australis still saw occasional usage, such as in scientific texts. The name Australia

6405-467: The Southern Hemisphere. The key diagnostic feature of Proteaceae is the inflorescence , which is often very large, brightly coloured and showy, consisting of many small flowers densely packed into a compact head or spike. Species of waratah boast such inflorescences ranging from 6–15 cm in diameter with a basal ring of coloured bracts. The leaves are spirally arranged, 10–20 cm long and 2–3 cm broad with entire or serrated margins. The name waratah comes from

Each of the species has its own distinctive natural distribution with minimal or no overlap. Climatic changes may have restricted the expansion of species distribution or led to its isolation in a particular region. However, waratahs can also grow outside of these natural distribution areas. Cultivation mostly occurs north of Sydney and in

Following the loss of its American colonies in 1783, the British Government sent a fleet of ships, the First Fleet , under the command of Captain Arthur Phillip , to establish a new penal colony in New South Wales . A camp was set up and the Union Flag raised at Sydney Cove , Port Jackson , on 26 January 1788,

7035-594: The convict system culminated in its abolition in the eastern colonies by the 1850s. Initially a free colony, Western Australia practised penal transportation from 1850 to 1868. The six colonies individually gained responsible government between 1855 and 1890, thus becoming elective democracies managing most of their own affairs while remaining part of the British Empire . The Colonial Office in London retained control of some matters, notably foreign affairs. In

Flower induction and initiation can simply occur when a plant has reached a mature enough age. However, in many plant species floral process occur in response to a number of environmental signals, or alternatively, are repressed by environmental signals. Floral initiation in T. speciosissima has been observed from mid-December, with floral buds developing more rapidly on older shoots and floral primordia emerging from mid-January to February. The floral primordia initiate over

7980-479: The interior deserts and Mediterranean-climate Southwest Australia . Lying on the Indo-Australian Plate , the mainland of Australia is the lowest and most primordial landmass on Earth with a relatively stable geological history. The landmass includes virtually all known rock types and from all geological time periods spanning more than 3.8 billion years of the Earth's history. The Pilbara Craton

8085-417: The island of New Guinea (considered geologically as part of the Australian continent), and in the Australian external territory of Heard Island and McDonald Islands . Seismic activity in the Australian mainland and Tasmania is also low, with the greatest number of fatalities having occurred in the 1989 Newcastle earthquake . The climate of Australia is significantly influenced by ocean currents, including

8190-620: The land and the environment, with stories of The Dreaming maintained through oral tradition , songs , dance and paintings. Certain groups engaged in fire-stick farming , fish farming , and built semi-permanent shelters . These practices have variously been characterised as " hunter-gatherer ", " agricultural ", "natural cultivation" and "intensification". Torres Strait Islander people first settled their islands at least 2,500 years ago. Culturally and linguistically distinct from mainland Aboriginal peoples, they were seafarers and obtained their livelihood from seasonal horticulture and

8295-443: The lignotuber. As such, it is not a recommended method but is useful for the fast growth of limited material. Rootstock and scion combinations are used for many woody perennials to provide the necessary mix of floral or fruit characteristics and cultural requirements. Tissue culture is very labour-intensive and would likely only be used in the case of rapidly increasing the number of plants from limited or valuable material. The process

8400-494: The location for the future federal capital of Canberra . While it was being constructed, Melbourne served as the temporary capital from 1901 to 1927. The Northern Territory was transferred from the control of South Australia to the Commonwealth in 1911. Australia became the colonial ruler of the Territory of Papua (which had initially been annexed by Queensland in 1883) in 1902 and of the Territory of New Guinea (formerly German New Guinea ) in 1920. The two were unified as

8505-448: The mainland. Australia is also one of 17 megadiverse countries. Australian forests are mostly made up of evergreen species, particularly eucalyptus trees in the less arid regions; wattles replace them as the dominant species in drier regions and deserts. Among well-known Australian animals are the monotremes (the platypus and echidna ); a host of marsupials , including the kangaroo , koala , and wombat , and birds such as

8610-474: The mid-19th century, explorers such as Burke and Wills charted Australia's interior. A series of gold rushes beginning in the early 1850s led to an influx of new migrants from China , North America and continental Europe, as well as outbreaks of bushranging and civil unrest; the latter peaked in 1854 when Ballarat miners launched the Eureka Rebellion against gold license fees. The 1860s saw

8715-602: The next two decades, social and economic reforms, together with the establishment of a Legislative Council and Supreme Court , saw the penal colony transition to a civil society. The indigenous population declined for 150 years following European settlement, mainly due to infectious disease. British colonial authorities did not sign any treaties with Aboriginal groups . As settlement expanded, tens of thousands of Indigenous people and thousands of settlers were killed in frontier conflicts while settlers dispossessed surviving Indigenous peoples of most of their land. In 1803,

8820-488: The observation that fertiliser application immediately after transplant of waratahs in the field often leads to high mortalities. Other studies have reported a strong growth response to high nutrient levels, particularly phosphorus. As yet, the details of this response are not yet clear and suggest a complex nitrogen-phosphorus relationship. Earlier work (1963) on related species, had indicated that fertiliser application may hasten maturation and give early flowering. If fertiliser

8925-498: The oldest living culture in the world. Australia's written history commenced with Dutch exploration of most of the coastline in the 17th-century. British colonisation began in 1788 with the establishment of the penal colony of New South Wales . By the mid-19th century, most of the continent had been explored by European settlers and five additional self-governing British colonies were established, each gaining responsible government by 1890. The colonies federated in 1901, forming

9030-457: The plant is the high amount of genetic and therefore morphological variability present in the flowers produced. The need to lift the quality and consistency of cut flower product has been repeatedly highlighted by industry reviews. Inconsistency of product is a key impediment to further industry growth. In many genera of Proteaceae the inflorescence is very large and showy, often in bright colours, consisting of many small flowers densely packed into

9135-428: The political systems of the United Kingdom (a fused executive , constitutional monarchy and strong party discipline ) and the United States ( federalism , a written constitution and strong bicameralism with an elected upper house), resulting in a distinct hybrid. Federal government power is partially separated between three groups: Charles III reigns as King of Australia and is represented in Australia by

9240-594: The protection of threatened species. Numerous protected areas have been created under the National Strategy for the Conservation of Australia's Biological Diversity to protect and preserve unique ecosystems; 65 wetlands are listed under the Ramsar Convention , and 16 natural World Heritage Sites have been established. Australia was ranked 21st out of 178 countries in the world on

9345-480: The rate of 6 to 7 centimetres a year. The Australian mainland's continental crust , excluding the thinned margins, has an average thickness of 38   km, with a range in thickness from 24 km to 59 km. Australia's geology can be divided into several main sections, showcasing that the continent grew from west to east: the Archaean cratonic shields found mostly in the west, Proterozoic fold belts in

9450-545: The remaining constitutional ties between Australia and the United Kingdom while maintaining the monarch in her independent capacity as Queen of Australia . In a 1999 constitutional referendum , 55% of voters rejected abolishing the monarchy and becoming a republic. Following the September 11 attacks on the United States, Australia joined the United States in fighting the Afghanistan War from 2001 to 2021 and

9555-419: The resources of their reefs and seas. Agriculture also developed on some islands and villages appeared by the 1300s. By the mid-18th century in northern Australia, contact, trade and cross-cultural engagement had been established between local Aboriginal groups and Makassan trepangers , visiting from present-day Indonesia. The Dutch are the first Europeans that recorded sighting and making landfall on

9660-491: The rise of blackbirding , where South Sea Islanders were coerced or abducted into indentured labour, mainly by Queensland colonists. From 1886, Australian colonial governments began removing many Aboriginal children from their families and communities, justified on the grounds of child protection and forced assimilation policies. The Second Boer War (1899–1902) marked the largest overseas deployment of Australia's colonial forces . On 1 January 1901, federation of

9765-424: The shade. Paul Nixon (1997) in his book ‘The Waratah’ claims that ‘the ideal situation is to have rich, well drained, deep soil with a north-easterly aspect giving the plants full sun until the flowers buds have initiated and then put shade cloth over the bushes until they have flowered’. A primary consideration for cultivation is water drainage. The waratah naturally grows in poor, sandy soils where it thrives due to

9870-510: The soils excellent water draining properties. Drainage properties can be linked to aspect and as a result plants grown on a north easterly aspect will generally flower 1–2 weeks earlier than a westerly aspect at the same location. Watering systems must also be carefully considered to coincide with correct drainage. As an Australian native the waratah is a sturdy plant well adapted to coping with harsh environments and low rainfall. Watering systems are still necessary for cultivation in order to produce

9975-422: The south-west coastal regions, and it rarely flowers in glasshouses. For some time the waratah has had a reputation as a difficult plant. It has a complex culture and for many years there have been cases of people trying to establish the plant only to have the attempt fail. This can be the effect of unsuitable soil conditions, aspect or climate. The waratah is also a slow plant to mature with a flowering period that

10080-501: The species concerned. The style is thickened at the distal end to form a 'pollen-presenter'. Pollen presenters have an area on the style end that presents the pollen to the pollinator. The stigma is initially trapped within the perianth and as the style grows it becomes bent until it splits the perianth and the pistil is released to spring upright. An open inflorescence usually contains functionally male and female flowers at any one time. Inflorescences range from 6–15 cm in diameter with

10185-682: The spread of the SARS-CoV-2 virus . Surrounded by the Indian and Pacific oceans, Australia is separated from Asia by the Arafura and Timor seas, with the Coral Sea lying off the Queensland coast, and the Tasman Sea lying between Australia and New Zealand. The world's smallest continent and sixth-largest country by total area , Australia—owing to its size and isolation—is often dubbed

10290-413: The stem thinning until it eventually rots and the seedling topples over. The problem is often associated with and encouraged by excessively wet conditions. Another major issue for production is bract browning – a discolouration of the showy floral bracts of the floral head occurring prior to harvest. Bract browning has been a major restraint to financial returns due to reduced cut flower quality. Browning

10395-697: The subtribe Embothriinae. The genus was first described by Robert Brown in 1810 from the type species Telopea speciosissima . There are five species of plant within the genus, all of which readily hybridize in cultivation. There are two main branches, with one being the species pair of T. speciosissima and T. aspera , with the other lineage giving rise to T. truncata first, then T. oreades and T. mongaensis . The speciosissima-aspera lineage (clade) has two synapomorphies —distinguishing common characteristics presumed not present in ancestors—leaves with toothed margins, and large red involucral bracts. The truncata-oreades-mongaensis lineage has flowers that open from

10500-406: The thylacine. Many of Australia's ecoregions, and the species within those regions, are threatened by human activities and introduced animal, chromistan , fungal and plant species. All these factors have led to Australia's having the highest mammal extinction rate of any country in the world. The federal Environment Protection and Biodiversity Conservation Act 1999 is the legal framework for

10605-407: The value of the crop. Chemicals with zylene or toluene should not be used as the will not be tolerated by the plant. There are also issues of fungal infection . Oomycete and fungal species cause stem rot ( Phytophthora spp.) and root rot ( Rhizoctonia spp.) that can ultimately cause plant death but can usually be controlled by adequate drainage. A problem for production that emanates from within

10710-615: Was Australia's warmest recorded year, and the 2019–2020 bushfire season was the country's worst on record . Australia's greenhouse gas emissions per capita are among the highest in the world. Water restrictions are frequently in place in many regions and cities of Australia in response to chronic shortages due to urban population increases and localised drought. Throughout much of the continent, major flooding regularly follows extended periods of drought, flushing out inland river systems, overflowing dams and inundating large inland flood plains, as occurred throughout Eastern Australia in

10815-413: Was established in 1829, evolving into the largest Australian colony by area, Western Australia . In accordance with population growth, separate colonies were carved from New South Wales: Tasmania in 1825, South Australia in 1836, New Zealand in 1841, Victoria in 1851, and Queensland in 1859. South Australia was founded as a free colony—it never accepted transported convicts. Growing opposition to

10920-579: Was one of the founding members of the League of Nations in 1920, and the United Nations in 1945. The Statute of Westminster 1931 formally ended the ability of the UK to pass federal laws without Australia's consent. Australia adopted it in 1942, but it was backdated to 1939 to confirm the validity of legislation passed during World War II. The Australian Capital Territory was formed in 1911 as

11025-470: Was popularised by the explorer Matthew Flinders , who said it was "more agreeable to the ear, and an assimilation to the names of the other great portions of the Earth". The first time that Australia appears to have been officially used was in April 1817, when Governor Lachlan Macquarie acknowledged the receipt of Flinders' charts of Australia from Lord Bathurst . In December 1817, Macquarie recommended to
