Cordyline australis. Cordyline australis, commonly known as the cabbage tree, tī kōuka or cabbage-palm, is a widely branched monocot tree endemic to New Zealand.It grows up to 20 (m) tall with a stout trunk and sword-like leaves, which are clustered at the tips of the branches and can be up to 1 (m) long. With its tall, straight trunk and dense, rounded heads, it is a characteristic feature of the New Zealand landscape. Its fruit is a favourite food source for the kererū and other native birds. It is common over a wide latitudinal range from the far north of the North.

Cordyline australis. Island at 34° 25′S to the south of the South Island at 46° 30′S. Absent from much of Fiordland, it was probably introduced by Māori to the Chatham Islands at 44° 00′S and to Stewart Island / Rakiura at 46° 50′S. It grows in a broad range of habitats, including forest margins, river banks and open places, and is abundant near swamps. The largest known tree with a single trunk is growing at Pakawau, Golden Bay / Mohua. It is estimated to be 400 or 500 years old, and stands 17 (m) tall with a circumference of 9 (m) at.

Cordyline australis. the base.Known to Māori as , the tree was used as a source of food, particularly in the South Island, where it was cultivated in areas where other crops would not grow. It provided durable fibre for textiles, anchor ropes, fishing lines, baskets, waterproof rain capes and cloaks, and sandals. Hardy and fast growing, it is widely planted in New Zealand gardens, parks and streets, and numerous cultivars are available. The tree can also be found in large numbers in island restoration projects such as Tiritiri Matangi Island, where it was among the first seedling trees to be planted.It is.

Cordyline australis. also grown as an ornamental tree in higher latitude Northern Hemisphere countries with maritime climates, including parts of the upper West Coast of the United States, Canada and the British Isles, where its common names include Torbay palm and Torquay palm. It does not do well in hot tropical climates like the Caribbean, Queensland, Southeast Asia or Florida.## Description."Cordyline australis" grows up to 20 (m) tall with a stout trunk 1.5 to 2 (m) in diameter. Before it flowers, it has a slender unbranched stem. The first flowers typically appear at 6 to 10 years old, in spring. The right.

Cordyline australis. conditions can reduce the first flowering age to 3 years (Havelock North, 2015 mast year). After the first flowering, it divides to form a much-branched crown with tufts of leaves at the tips of the branches. Each branch may fork after producing a flowering stem. The pale to dark grey bark is corky, persistent and fissured, and feels spongy to the touch.The long narrow leaves are sword-shaped, erect, dark to light green, 40 to 100 (cm) long and 3 to 7 (cm) wide at the base, with numerous parallel veins. The leaves grow in crowded clusters at the ends of.

Cordyline australis. the branches, and may droop slightly at the tips and bend down from the bases when old. They are thick and have an indistinct midrib. The fine nerves are more or less equal and parallel. The upper and lower leaf surfaces are similar.In spring and early summer, sweetly perfumed flowers are produced in large, dense panicles (flower spikes) 60 to 100 (cm) long, bearing well-spaced to somewhat crowded, almost sessile to sessile flowers and axes. The flowers are crowded along the ultimate branches of the panicles. The bracts which protect the developing flowers often have a distinct pink tinge before.

Cordyline australis. the flowers open. In south Canterbury and North Otago the bracts are green.The individual flowers are 5 to 6 (mm) in diameter, the tepals are free almost to the base, and reflexed. The stamens are about the same length as the tepals. The stigmas are short and trifid. The fruit is a white berry 5 to 7 (mm) in diameter which is greedily eaten by birds. The nectar attracts great numbers of insects to the flowers.Large, peg-like rhizomes, covered with soft, purplish bark, up to 3 (m) long in old plants, grow vertically down beneath the ground. They serve to.

Cordyline australis. anchor the plant and to store fructose in the form of fructan. When young, the rhizomes are mostly fleshy and are made up of thin-walled storage cells. They grow from a layer called the secondary thickening meristem.## Regional diversity.New Zealand's native "Cordyline" species are relics of an influx of tropical plants that arrived from the north 15 million years ago in the warm Miocene era. Because it has evolved in response to the local climate, geology and other factors, "C. australis" varies in appearance from place to place. This variation can alter the overall appearance of the tree, canopy shape.

Cordyline australis. and branch size, the relative shape and size of the leaves, and their colour and stiffness. There may also be invisible adaptations for resistance to disease or insect attack. Some of these regional provenances are different enough to have been named by North Island Māori: in the north, in the central uplands, in the east and in the west.In Northland, "C. australis" shows a great deal of genetic diversity—suggesting it is where old genetic lines have endured. Some trees in the far north have floppy, narrow leaves, which botanist Philip Simpson attributes to hybridisation with "C. pumilio", the dwarf cabbage.

Cordyline australis. tree. In eastern Northland, "C. australis" generally has narrow, straight dark green leaves, but some trees have much broader leaves than normal and may have hybridised with the Three Kings cabbage tree, "C. obtecta", which grows at North Cape and on nearby islands. These "obtecta"-like characteristics appear in populations of "C. australis" along parts of the eastern coastline from the Karikari Peninsula to the Coromandel Peninsula. In western Northland and Auckland, a form often called grows. When young, are generally very spindly, and are common in young kauri forests. When growing in the open, can become massive trees with numerous,.

Cordyline australis. long thin branches and relatively short, broad leaves.In the central Volcanic Plateau, cabbage trees are tall, with stout, relatively unbranched stems and large stiff straight leaves. Fine specimens are found along the upper Whanganui River. On old trees, the leaves tend to be relatively broad. The leaves radiate strongly, suggesting that tī manu is adapted to the cold winters of the upland central plateau. It may have originated in the open country created by lava, volcanic ash, and pumice. Trees of the tī manu type are also found in northern Taranaki, the King Country and the Bay of Plenty lowlands.Tarariki.

Cordyline australis. are found in the east of the North Island from East Cape to the Wairarapa. Māori valued the narrow spiky leaves as a source of particularly tough, durable fibre. Tarariki's strong leaf fibres may be an adaptation to the region's hot, dry summers. In parts of the Wairarapa, the trees are particularly spiky, with stiff leaves and partially rolled leaf-blades. The trees near East Cape, by contrast, have leaves that hang laxly on the tree. In Hawke's Bay, some trees have greener, broader leaves, and this may be because of wharanui characteristics brought in across the main divide through the.

Cordyline australis. Manawatū Gorge.Wharanui grow to the west of the North Island's main divide. They have long, broad flaccid leaves, which may be an adaptation to persistent westerly winds. The wharanui type occurs in Wellington, Horowhenua and Whanganui, and extends with some modifications to the southern Taranaki coast. In Taranaki, cabbage trees generally have a compact canopy with broad straight leaves. In the South Island, wharanui is the most common form, but it is variable. The typical form grows, with little variation, from Cape Campbell to the northern Catlins, and from the eastern coast to the foothills of the Southern Alps /.

Cordyline australis. Kā Tiritiri o te Moana. In Marlborough's Wairau Valley, cabbage trees tend to retain their old, dead leaves, lending them an untidy appearance. The climate there is an extreme one, with hot, dry summers and cold winters.In north-west Nelson, there are three ecotypes defined by soil and exposure. Trees growing on limestone bluffs have stiff, blue-green leaves. On the river flats, the trees are tall with narrow, lax, dark green leaves, and an uneven canopy. They resemble the cabbage trees of the North Island's East Cape. Along the coast to the far west, the trees are robust with broad, bluish.

Cordyline australis. leaves. The latter two forms extend down the West Coast, with the lax-leaved forms growing in moist, fertile, sheltered river valleys while the bluish-leaved forms prefer rocky slopes exposed to the full force of the salt-laden coastal winds. In Otago, cabbage trees gradually become less common towards the south until they come to an end in the northern Catlins. They reappear on the south coast at Waikawa, Southland, but they are not the wharanui type. Rather they are vigorous trees with broad, green leaves and broad canopies. They extend along the coast towards Fiordland, and inland to the margins of.

Cordyline australis. some of the glacier-fed lakes. Very vigorous when they are young, these trees seem well adapted to the very cold winters of the south.A study of seedlings grown from seed collected in 28 areas showed a north-south change in leaf shape and dimensions. Seedling leaves get longer and narrower southwards. Seedlings often have leaves with red-brown pigmentation which disappears in older plants, and this coloration becomes increasingly common towards the south. The changes in shape—leaves getting narrower and more robust from north to south and from lowland to montane—suggest adaptations to colder weather.## Taxonomy and names."Cordyline australis" was collected in.

Cordyline australis. 1769 by Sir Joseph Banks and Dr Daniel Solander, naturalists on the "Endeavour" during Lieutenant James Cook's first voyage to the Pacific. The type locality is Queen Charlotte Sound / Tōtaranui. It was named "Dracaena australis" by Georg Forster who published it as entry 151 in his "Florulae Insularum Australium Prodromus" of 1786. It is sometimes still sold as a "Dracaena", particularly for the house plant market in Northern Hemisphere countries. In 1833, Stephan Endlicher reassigned the species to the genus,"Cordyline".The genus name "Cordyline" derives from an Ancient Greek word for a club ("kordyle"), a reference to the enlarged underground.

Cordyline australis. stems or rhizomes, while the species name "australis" is Latin for "southern". The common name "cabbage tree" is attributed by some sources to early settlers having used the young leaves as a substitute for cabbage. However the name probably predates the settlement of New Zealand — Georg Forster, writing in his "Voyage round the World" of 1777 about the events of Friday, April 23, 1773, refers on page 114 to the discovery of a related species in Fiordland as "not the true cabbage palm" and says "the central shoot, when quite tender, tastes something like an almond's kernel, with a.

Cordyline australis. little of the flavour of cabbage." Forster may have been referring to the cabbage palmetto ("Sabal palmetto") of Florida, which resembles the Cordyline somewhat, and was named for the cabbage-like appearance of its terminal bud."Cordyline australis" is the tallest of New Zealand's five native "Cordyline" species. Of these, the commonest are "C. banksii", which has a slender, sweeping trunk, and "C. indivisa", a handsome plant with a trunk up to 8 (m) tall bearing a massive head of broad leaves up to 2 (m) long. In the far north of New Zealand, "C. australis" can be distinguished by its larger.

Cordyline australis. heavily branched tree form, narrower leaves and smaller seeds from "C. obtecta", the Three Kings cabbage tree, its closest relative. "C. australis" is rather variable, and forms from the northern offshore islands may be hybrids with "C. obtecta". Hybrids with "C. pumilio" and "C. banksii" also occur often where the plants are in close vicinity, because they flower at about the same time and share the chromosome number 2n=38, with "C. australis".The tree was well known to Māori before its scientific discovery. The generic Māori language term for plants in the genus "Cordyline" is "tī", and names recorded as specific.

Cordyline australis. to "C. australis" include "tī kōuka", "tī kāuka", "tī rākau", "tī awe", "tī pua", and "tī whanake". Each tribe had names for the tree depending on its local uses and characteristics. Simpson reports that the names highlight the characteristics of the tree that were important to Māori. These include what the plant looked like—whether it was a large tree ("tī rākau", "tī pua"), the whiteness of its flowers ("tī puatea"), whether its leaves were broad ("tī wharanui"), twisted along the edges ("tī tahanui"), or spiky ("tī tarariki"). Other names refer to its uses—whether its fruit attracted birds ("tī manu"), or.

Cordyline australis. the leaves were particularly suitable for making ropes ("tī whanake") and nets ("tī kupenga"). The most widely used name, "tī kōuka", refers to the use of the leaf hearts as food.## Ecology.## Habitat.A quote from Philip Simpson sums up the wide range of habitats the cabbage tree occupied in early New Zealand, and how much its abundance and distinctive form shaped the impression travellers received of the country:"In primeval New Zealand cabbage trees occupied a range of habitats, anywhere open, moist, fertile and warm enough for them to establish and mature: with forest; around the rocky coast; in lowland swamps,.

Cordyline australis. around the lakes and along the lower rivers; and perched on isolated rocks. Approaching the land from the sea would have reminded a Polynesian traveller of home, and for a European traveller, conjured up images of the tropical Pacific"."Cordyline australis" occurs from North Cape to the very south of the South Island, where it becomes less and less common, until it reaches its southernmost natural limits at Sandy Point (46° 30' S), west of Invercargill near Oreti Beach. It is absent from much of Fiordland, probably because there is no suitable habitat, and is unknown on the subantarctic islands to.

Cordyline australis. the south of New Zealand, probably because it is too cold. It occurs on some offshore islands—Poor Knights, Stewart and the Chathams—but was probably introduced by Māori. In the Stewart Island region, it is rare, growing only on certain islands, headlands and former settlement sites where it may have been introduced by muttonbird collectors, while on the Chatham Islands it is also largely "a notable absentee".Generally a lowland species, it grows from sea level to about 1000 (m), reaching its upper limits on the volcanoes of the central North Island, where eruptions have created open spaces for it to exploit,.

Cordyline australis. and in the foothills of the Southern Alps in the South Island, where deforestation may have played a part in giving it room to grow. In the central North Island, it has evolved a much sturdier form (with the Māori name "tī manu", meaning "with branches bearing broad, straight upright leaves"). This form resembles that found in the far south of the South Island, suggesting that they are both adapted to cold conditions."Cordyline australis" is a light-demanding pioneer species, and seedlings die when overtopped by other trees. To grow well, young plants require open space so they are not shaded.

Cordyline australis. out by other vegetation. Another requirement is water during the seedling stage. Although adult trees can store water and are drought resistant, seedlings need a good supply of water to survive. This stops the species from growing in sand dunes unless there are wet depressions present, and from hillsides unless there is a seepage area. The fertility of the soil is another factor—settlers in Canterbury used the presence of the species to situate their homesteads and gardens. The fallen leaves of the tree also help to raise the fertility of the soil when they break down. Another factor is temperature,.

Cordyline australis. especially the degree of frost. Young trees are killed by frost, and even old trees can be cut back. This is why "C. australis" is absent from upland areas and from very frosty inland areas.Early European explorers of New Zealand described "jungles of cabbage trees" along the banks of streams and rivers, in huge swamps and lowland valleys. Few examples of this former abundance survive today—such areas were the first to be cleared by farmers looking for flat land and fertile soil. In modern New Zealand, cabbage trees usually grow as isolated individuals rather than as parts of a healthy.

Cordyline australis. ecosystem.## Reproduction.The cabbage tree's year begins in autumn among the tight spike of unopened leaves projecting from the centre of each tuft of leaves. Some of the growing tips have changed from making leaves to producing inflorescences for the coming spring, and around these, two or three buds begin to produce leaves. The inflorescence and the leaf buds pass the winter protected by the enveloping spike of unopened leaves. Months later in spring or early summer, it bears its flowers on the outside of the tree, exposed to insects and birds.Flowering takes place over a period of four to six.

Cordyline australis. weeks, giving maximum exposure to pollinating insects. The flowers produce a sweet perfume which attracts large numbers of insects. The nectar produced by the flowers contains aromatic compounds, mainly esters and terpenes, which are particularly attractive to moths. Bees use the nectar to produce a light honey to feed their young and increase the size of the hive in the early summer. It takes about two months for the fruit to ripen, and by the end of summer a cabbage tree can have thousands of small fruits available for birds to eat and disperse. The strong framework of the inflorescence.

Cordyline australis. can easily bear the weight of heavy birds like the New Zealand pigeon, which was formerly the major disperser of the seeds.Each fruit contains three to six shiny, black seeds which are coated in a charcoal-like substance called phytomelan. The latter may serve to protect the seeds from the digestive process in the gut of a bird. The seeds are also rich in linoleic acid as a food source for the developing embryo plant, a compound which is also important in the egg-laying cycle of birds. Because it takes about two years for a particular stem to produce an inflorescence,.

Cordyline australis. cabbage trees tend to flower heavily in alternative years, with a bumper flowering every three to five years. Each inflorescence bears 5,000 to 10,000 flowers, so a large inflorescence may carry about 40,000 seeds, or one million seeds for the whole tree in a good flowering year—hundreds of millions for a healthy grove of trees.## Response to fire."Cordyline australis" is one of the few New Zealand forest trees that can recover from fire. It can renew its trunk from buds on the protected rhizomes under the ground. This gives the tree an advantage because it can regenerate itself quickly and.

Cordyline australis. the fire has eliminated competing plants. Cabbage tree leaves contain oils which make them burn readily. The same oils may also slow down the decay of fallen leaves, so that they build up a dense mat that prevents the seeds of other plants from germinating. When the leaves do break down, they form a fertile soil around the tree. Cabbage tree seed also has a store of oil, which means it remains viable for several years. When a bushfire has cleared the land of vegetation, cabbage tree seeds germinate in great numbers to make the most of the light and.

Cordyline australis. space opened up by the flames.Older trees sometimes grow epicormic shoots directly from their trunks after storm or fire damage. Aerial rhizomes can also be produced from the trunk if it sustains damage or has become hollow, and grow down into the soil to regenerate the plant. Such regeneration can lead to trees of great age with multiple trunks.## Biodiversity.Many plants and animals are associated with "C. australis" in healthy ecosystems. The most common epiphytes are ferns, astelias and orchids. Old trees often carry large clumps of the climbing fern "Asplenium", and in moist places, filmy ferns and kidney ferns.

Cordyline australis. cling to the branches. "Astelia" species and "Collospermum" often establish in the main fork of the tree, and one tree can host several species of native orchid. Other common epiphytes include "Griselinia lucida", as well as a range of mosses, liverworts, lichens and fungi. Two fungus species which infect living tissue—"Phanaerochaeta cordylines" and "Sphaeropsis cordylines"—occur almost exclusively on "C. australis".Animals and birds associated with "C. australis" include lizards which forage among the flowers, including the gold-striped gecko which is well camouflaged for life among the leaves of the tree. New Zealand bellbirds like to nest under the dead leaves or.

Cordyline australis. among the flower stalks, and paradise shelducks commonly build their nests in the base of an old cabbage tree standing in the middle of a field. Red-crowned parakeets are often seen foraging in cabbage trees. In South Canterbury, long-tailed bats shelter during the day in the hollow branches, which would once have provided nesting holes for many birds.The berries of "C. australis" are enjoyed by bellbirds, tūī, and kererū. Māori sometimes planted groves of cabbage trees () to attract kererū which could be snared when they came to eat the berries. Reminiscing in 1903 about life in New Zealand sixty.

Cordyline australis. or more years earlier, George Clarke describes how such a tapu grove of cabbage trees would attract huge numbers of pigeons: "About four miles from our house, there was a great preserve of wood pigeons, that was made as tapu as the native chiefs could devise. At a certain season, the pigeons came in vast flocks to feed on the white berries of the Ti tree (bracœna) [sic] and got so heavy with fat that they could hardly fly from one tree to another. No gun was allowed in the place. The Maoris, with a long slender rod and a.

Cordyline australis. slip noose at the end, squatted under the leaves and noiselessly slipped the noose over the necks of the stupid pigeons as they were feeding." As the native birds have vanished from much of New Zealand with the clearing of forests, it is now flocks of starlings which descend upon the fruit.The nectar of the flowers is sought after by insects, bellbirds, tūī, and stitchbirds. The leaves and the rough bark provide excellent homes for insects such as caterpillars and moths, small beetles, fly larvae, wētā, snails and slugs. Many of these are then eaten by birds such as saddlebacks.

Cordyline australis. and robins. The rough bark also provides opportunities for epiphytes to cling and grow, and lizards hide amongst the dead leaves, coming out to drink the nectar and to eat the insects. Good flowering seasons occur every few years only. While it is said that they foretell dry summers, it has been observed that they tend to follow dry seasons.Insects, including beetles, moths, wasps and flies, use the bark, leaves and flowers of the tree in various ways. Some feed or hide camouflaged in the skirt of dead leaves, a favourite dry place for wētā to hide in winter. Many.

Cordyline australis. of the insect companions of the tree have followed it into the domesticated surroundings of parks and home gardens. If the leaves are left to decay, the soil underneath cabbage trees becomes a black humus that supports a rich array of amphipods, earthworms and millipedes.There are nine species of insect only found on "C. australis", of which the best known is "Epiphryne verriculata", the cabbage tree moth, which is perfectly adapted to hide on a dead leaf. Its caterpillars eat large holes and wedges in the leaves. The moth lays its eggs at the base of the central spike of.

Cordyline australis. unopened leaves. The caterpillars eat holes in the surface of the leaves and leave characteristic notches in the leaf margins. They can infest young trees but seldom damage older trees, which lack the skirt of dead leaves where the parent moths like to hide.## Threats, pests and diseases.## Sudden decline.Cases of sick and dying trees of "C. australis" were first reported in the northern part of the North Island in 1987. The syndrome, eventually called Sudden Decline, soon reached epidemic proportions in Northland and Auckland. Affected trees usually suffer total defoliation within 2 to 12 months. The foliage turns yellow,.

Cordyline australis. and the oldest leaves wither and fall off. Growth of leaves ceases, and eventually all the leaves fall, leaving dead branches, often with the dried-out flowering panicles still attached. At the same time, the bark on the trunk becomes loose and detaches easily. The greatest number of dead trees (18 to 26 percent) was recorded around Auckland.For some years, the cause of the disease was unknown, and hypotheses included tree ageing, fungi, viruses, and environmental factors such as an increase in ultra-violet light. Another hypothesis was that a genetic problem may have been induced in Northland and Auckland by the.

Cordyline australis. thousands of cabbage trees brought into the area from elsewhere and planted in gardens and parks. The Lands and Survey Department had a native plant nursery at Taupo in the central North Island, which was used to grow plants for use in parks, reserves and carparks. In many Northland parks, cabbage trees from the central North Island were growing and flowering within metres of natural forms. Any offspring produced might have been poorly adapted to local conditions. After nearly five years of work, scientists found the cause was a bacterium "Phytoplasma australiense", which may be spread from tree to tree.

Cordyline australis. by a tiny sap-sucking insect, the introduced passion vine hopper.Populations of "C. australis" were decimated in some parts of New Zealand because of Sudden Decline. In some areas, particularly in the north, no big trees are left. Although Sudden Decline often affects cabbage trees in farmland and open areas, trees in natural forest patches continue to do well. Trees in the southern North Island and northern South Island are generally unaffected with few dead branches and no symptoms of Sudden Decline. By 2010, there was evidence to suggest the severity of the disease was lessening.## Rural decline.The plight of "Cordyline.

Cordyline australis. australis" in the Sudden Decline epidemic drew attention to another widespread threat to the tree in rural areas throughout New Zealand. Rural Decline was the name proposed by botanists to refer to a decline in health of older trees in pasture and grazed shrubland, leading over many years to the loss of upper branches and eventual death.Often farmers would leave a solitary cabbage tree—or even groves of trees—standing after the swamps were drained. Most of these trees will slowly die out because livestock eat the seedlings and damage the trunks and roots of adult trees. When a cabbage tree is.

Cordyline australis. the only shade in a field, stock will shelter underneath it, damaging the bark by rubbing against it, and compacting the soil around the tree. Cows, sheep, goats, and deer eat the nutritious tissue under the bark of cabbage trees. Once the trunk has been damaged by animals, it seldom heals and the wounds get bigger over time. Eventually the tissue in the centre of the stem rots away and a cavity forms along its entire length. The trunk becomes misshapen or completely ring-barked for a metre above the ground. Often the growth layer dies and the injuries may lead.

Cordyline australis. to bacterial or fungal infections that spread into the branches until the canopy too begins to die. Other factors thought to contribute to Rural Decline include wood-rotting fungi like "Phanerochaete cordylines", micro-organisms which cause saprobic decay and leaf-feeding caterpillars.Other mammals can be destructive. Possums tend not to eat the leaves of the tree, but are very fond of eating the sugar-rich flowering stalks as they emerge. They also like using the tree as a sleeping place. Rabbits can be more destructive, especially during periods of drought, when they have been seen to eat through the base until a tree falls,.

Cordyline australis. and then eating the fallen tree completely. Horses can also fell a tree by eating through the trunk.## Māori cultural uses.In traditional times, Māori had a rich knowledge of the cabbage tree, including spiritual, ecological and many practical aspects of its use. While much of that specialised knowledge was lost after the European settlement of New Zealand, the use of the tree as food and medicine has persisted, and the use of its fibres for weaving is becoming more common.## Food.The stems and fleshy rhizomes of "C. australis" are high in natural sugars and were steam-cooked in earth ovens ("umu.

Cordyline australis. tī", a large type of "hāngi") to produce "kāuru", a carbohydrate-rich food used to sweeten other foods. The growing tips or leaf hearts were stripped of leaves and eaten raw or cooked as a vegetable, when they were called "kōuka"—the origin of the Māori name of the tree. The southern limit of kūmara (sweet potato) cultivation was at Banks Peninsula at 43°S, and south of there a culture developed around "C. australis". Natural and planted groves of the cabbage tree were harvested.Large parties trimmed the cut stems, and left them to dry for days or weeks. As well as stems,.

Cordyline australis. the rhizomes—extensions of the trunk below the surface of the ground shaped like enormous carrots—were also dug up to be cooked. In the early 1840s, Edward Shortland said Māori preferred rhizomes from trees growing in deep rich soil. They dug them in spring or early summer just before the flowering of the plant, when they were at their sweetest. November was the favourite month for preparing kāuru in the South Island.After drying, the harvested stems or rhizomes were steamed for 24 hours or more in the umu tī pit. Steaming converted the carbohydrate fructan in the stems to very sweet.

Cordyline australis. fructose. The cooked stems or rhizomes were then flattened by beating and carried back to villages for storage. Kāuru could be stored dry until the time came to add it to fern root and other foods to improve their palatability. The sugar in the stems or rhizomes would be partially crystallised, and could be found mixed in a sugary pulp with other matter between the fibres of the root, which were easily separated by tearing them apart. Kāuru could also be dipped in water and chewed, and was said to smell and taste like molasses.Evidence of large cooking pits (umu.

Cordyline australis. tī) can still be found in the hills of South Canterbury and North Otago, where large groves of cabbage trees still stand. Europeans used the plant to make alcohol, and the often fearsome brews were relished by whalers and sealers.The kōata, the growing tip of the plant, was eaten raw as medicine. When cooked, it was called the kōuka. If the spike of unopened leaves and a few outer leaves is gripped firmly at the base and bent, it will snap off. The leaves can be removed, and what remains is like a small artichoke heart that can be steamed,.

Cordyline australis. roasted or boiled to make kōuka, a bitter vegetable available at any time of the year. Kōuka is delicious as a relish with fatty foods like eel, muttonbirds, or pigeons, or in modern times, pork, mutton and beef. Different trees were selected for their degree of bitterness, which should be strong for medicinal use, but less so when used as a vegetable.## Fibre.A tough fibre was extracted from the leaves of "C. australis", and was valued for its strength and durability especially in seawater. The leaves are suitable for weaving in its raw state, without any need to further process.

Cordyline australis. the fibres. The leaves were used for making anchor ropes and fishing lines, cooking mats, baskets, sandals and leggings for protection when travelling in the South Island high country, home of the prickly speargrasses ("Aciphylla") and tūmatakuru or matagouri ("Discaria toumatou"). Because of the water-resistant properties of the plant, the leaves were traditionally used for cooking baskets. Morere swings provided a source of amusement for Māori children. The ropes had to be strong, so they were often made from the leaves or fibre of "C. australis", which were much tougher than the fibres of New Zealand flax. The leaves were.

Cordyline australis. also used for rain capes, although the mountain cabbage tree "C. indivisa", was preferred. The fibre made from cabbage tree leaves is stronger than that made from New Zealand flax.## Medicine.The Māori used various parts of "Cordyline australis" to treat injuries and illnesses, either boiled up into a drink or pounded into a paste. The kōata, the growing tip of the plant, was eaten raw as a blood tonic or cleanser. Juice from the leaves was used for cuts, cracks and sores. An infusion of the leaves was taken internally for diarrhoea and used externally for bathing cuts. The leaves.

Cordyline australis. were rubbed until soft and applied either directly or as an ointment to cuts, skin cracks and cracked or sore hands. The young shoot was eaten by nursing mothers and given to children for colic. The liquid from boiled shoots was taken for other stomach pains. The seeds of "Cordyline australis" are high in linoleic acid, one of the essential fatty acids.## Cultivation today."Cordyline australis" is one of the most widely cultivated New Zealand native trees. In Northwest Europe and other cool oceanic climates, it is very popular as an ornamental tree because it looks like a palm tree. Hardy.

Cordyline australis. forms from the coldest areas of the southern or inland South Island tolerate Northern Hemisphere conditions best, while North Island forms are much more tender. It can also be grown successfully in Mediterranean climates. It is easily grown from fresh seed — seedlings often spontaneously appear in gardens from bird-dispersed seed — and can be grown very easily from shoot, stem and even trunk cuttings. It does well in pots and tubs.It grows well as far north as the eastern coast of Scotland, including the village of Portgower. It is more common in Southern England and in Ireland where it.

Cordyline australis. is grown all over the island. Although not a palm, it is locally named Cornish palm, Manx palm or Torbay palm. The last name is due to its extensive use in Torbay, it being the official symbol of that area, used in tourist posters promoting South Devon as the English Riviera. It also grows in southern Europe, California and Japan. Even though its natural distribution ranges from 34° S to 46°S, and despite its ultimately subtropical origins, it also grows at about five degrees from the Arctic Circle in Masfjorden, Norway, latitude 61ºN, in a microclimate protected from arctic winds.

Cordyline australis. and moderated by the Gulf Stream.## Cultivars.In the North Island, Māori cultivated selected forms of "C. australis" for food. One of these, called tī para or tī tāwhiti, was grown because it suckers readily and forms multiple fleshy rhizomes. A dwarf non-flowering selection of "C. australis", it has a rubbery, pulpy stem, and thick green leaves. Although it was recorded by the early naturalists, botanists only rediscovered it in the 1990s, being grown by gardeners as the cultivar "Cordyline" 'Thomas Kirk'. Recent and unpublished DNA work suggests it derives from "C. australis" of the central North Island."Cordyline" 'Ti Tawhiti' was.

Cordyline australis. "the subject of an intense discussion amongst the leading botanists of New Zealand at a meeting of the Royal Society ... in Wellington 100 years ago. It was saved from extinction because its dwarf form found favour with gardeners and it came to be known as Cordyline 'Kirkii' recording the interest Thomas Kirk had in the plant. Its origin as a Maori selection was forgotten until rediscovered in 1991. The name 'Tawhiti' is equivalent to 'Hawaiki' and indicates the traditional belief that the plant was introduced to Aotearoa by the ancestral canoes of Maori. However, it is more probable that.

Cordyline australis. the name arose from it being moved around its native land as a domesticated plant."Numerous cultivars of "C. australis" are sold within New Zealand and around the world. Like other "Cordyline" species, "C. australis" can produce sports which have very attractive colouration, including pink stripes and leaves in various shades of green, yellow or red. An early cultivar was published in France and England in 1870: "Cordyline australis" 'Lentiginosa' was described as having tinted leaves with brownish red spots. Other early cultivars included 'Veitchii' (1871) with crimson midribs, 'Atrosanguinea' (1882) with bronze leaves infused with red, 'Atropurpurea' (1886) and 'Purpurea'.

Cordyline australis. (1890) with purple leaves, and a range of variegated forms: 'Doucetiana' (1878), 'Argento-striata' (1888) and 'Dalleriana' (1890). In New Zealand and overseas, hybrids with other "Cordyline" species feature prominently in the range of cultivars available. New Plymouth plant breeders Duncan and Davies included hybrids of "C. australis" and "C. banksii" in their 1925 catalogue, and have produced many new cultivars since. In New Zealand, some of the coloured forms and hybrids seem to be more susceptible to attacks from the cabbage tree moth.Immature forms have become a popular annual house or ornamental plant under the name 'Spikes', or "Dracaena" 'Spikes'.

Cordyline australis. To add to the confusion, these may be misidentified as "Cordyline indivisa" (syn. "Dracaena indivisa")."C. australis" is hardy to USDA zones 8–11.## AGM cultivars.In cultivation in the United Kingdom, the following have received the Royal Horticultural Society's Award of Garden Merit:"C. australis" 'Albertii' 'Sundance' 'Torbay Dazzler', 'Torbay Red' (confirmed 2017) Barry L.

Coprinopsis lagopus. very dark-brown at center beneath the whitish to silvery grey veil but becomes paler towards the margin. As the mushroom matures, the shape of the cap becomes more conical or convex, and finally flattens out, with edges curved upward. The veil is initially whitish, then turns to a silvery grey or grey-brown; it eventually splits up, becoming hairy (fibrillose). The gills are freely attached to the stem, very thin and crowded closely together. Initially, the color of the gills is white, then progresses to grayish-brown then to black as the spores mature. In maturity the gill edges dissolve ("deliquesce") into.

Coprinopsis lagopus. the sides of the gills ("pleurocystidia") are abundant in large fruit bodies, fewer in number in the smaller specimens. These cells are oval, rounded at the apex with a bulge in the middle, and contracted into a stalk at the base. The length of these cells is typically 100–130 μm, with a width of 35–45 μm. Before the cap expands, each cystidium completely branches an interlamellar space, with both ends attached to the gills, help together by clasping "paraphyses". As the gill expands the cystidium breaks away from one gill and projects from the other gill. The basidia (spore-bearing cells).

Power inverter. A power inverter, inverter or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of rectifiers which were originally large electromechanical devices converting AC to DC.The input voltage, output voltage and frequency, and overall power handling depend on the design of the specific device or circuitry. The inverter does not produce any power; the power is provided by the DC source.A power inverter can be entirely electronic or may be a combination of mechanical effects (such as.

Power inverter. a rotary apparatus) and electronic circuitry.Static inverters do not use moving parts in the conversion process.Power inverters are primarily used in electrical power applications where high currents and voltages are present; circuits that perform the same function for electronic signals, which usually have very low currents and voltages, are called oscillators. Circuits that perform the opposite function, converting AC to DC, are called rectifiers.## Input and output.## Input voltage.A typical power inverter device or circuit requires a stable DC power source capable of supplying enough current for the intended power demands of the system. The input voltage depends on the.

Power inverter. are two basic designs for producing household plug-in voltage from a lower-voltage DC source, the first of which uses a switching boost converter to produce a higher-voltage DC and then converts to AC. The second method converts DC to AC at battery level and uses a line-frequency transformer to create the output voltage.## Square wave.This is one of the simplest waveforms an inverter design can produce and is best suited to low-sensitivity applications such as lighting and heating. Square wave output can produce "humming" when connected to audio equipment and is generally unsuitable for sensitive electronics.## Sine wave.A power inverter.

Power inverter. device that produces a multiple step sinusoidal AC waveform is referred to as a "sine wave inverter". To more clearly distinguish the inverters with outputs of much less distortion than the "modified sine wave" (three-step) inverter designs, the manufacturers often use the phrase "pure sine wave inverter". Almost all consumer grade inverters that are sold as a "pure sine wave inverter" do not produce a smooth sine wave output at all, just a less choppy output than the square wave (two-step) and modified sine wave (three-step) inverters. However, this is not critical for most electronics as they deal with the.

Power inverter. output quite well.Where power inverter devices substitute for standard line power, a sine wave output is desirable because many electrical products are engineered to work best with a sine wave AC power source. The standard electric utility provides a sine wave, typically with minor imperfections but sometimes with significant distortion.Sine wave inverters with more than three steps in the wave output are more complex and have significantly higher cost than a modified sine wave, with only three steps, or square wave (one step) types of the same power handling. Switch-mode power supply (SMPS) devices, such as personal computers or DVD.

Power inverter. players, function on modified sine wave power. AC motors directly operated on non-sinusoidal power may produce extra heat, may have different speed-torque characteristics, or may produce more audible noise than when running on sinusoidal power.## Modified sine wave.The modified sine wave is the sum of two square waves, one of which is delayed one-quarter of the period with respect to the other. The result is a waveform which has voltage steps of zero, peak positive, zero, peak negative and again zero. This voltage value sequence is repeated continuously. The resultant voltage waveform better approximates the shape of a sinusoidal voltage.

Power inverter. entirely without problems, but if the item has a mains transformer, this can overheat depending on how marginally it is rated.However, the load may operate less efficiently owing to the harmonics associated with a modified sine wave and produce a humming noise during operation. This also affects the efficiency of the system as a whole, since the manufacturer's nominal conversion efficiency does not account for harmonics. Therefore, pure sine wave inverters may provide significantly higher efficiency than modified sine wave inverters.Most AC motors will run on MSW inverters with an efficiency reduction of about 20% owing to the harmonic content.

Power inverter. DC supply, in the manner of the MSN designs, but the switching takes place at a far faster rate, typically many KHz, so that the varying width of the pulses can be smoothed to create the sine wave. If a microprocessor is used to generate the switching timing, the harmonic content and efficiency can be closely controlled.## Output frequency.The AC output frequency of a power inverter device is usually the same as standard power line frequency, 50 or 60 hertz. The exception is in designs for motor driving, where a variable frequency results in a variable speed control.Also, if the.

Power inverter. output of the device or circuit is to be further conditioned (for example stepped up) then the frequency may be much higher for good transformer efficiency.## Output voltage.The AC output voltage of a power inverter is often regulated to be the same as the grid line voltage, typically 120 or 240 VAC at the distribution level, even when there are changes in the load that the inverter is driving. This allows the inverter to power numerous devices designed for standard line power.Some inverters also allow selectable or continuously variable output voltages.## Output power.A power inverter will often have an overall.

Power inverter. battery from the others.## Applications.## DC power source usage.An inverter converts the DC electricity from sources such as batteries or fuel cells to AC electricity. The electricity can be at any required voltage; in particular it can operate AC equipment designed for mains operation, or rectified to produce DC at any desired voltage.## Uninterruptible power supplies.An uninterruptible power supply (UPS) uses batteries and an inverter to supply AC power when mains power is not available. When mains power is restored, a rectifier supplies DC power to recharge the batteries.## Electric motor speed control.Inverter circuits designed to produce a variable output.

Power inverter. voltage range are often used within motor speed controllers.The DC power for the inverter section can be derived from a normal AC wall outlet or some other source. Control and feedback circuitry is used to adjust the final output of the inverter section which will ultimately determine the speed of the motor operating under its mechanical load. Motor speed control needs are numerous and include things like: industrial motor driven equipment, electric vehicles, rail transport systems, and power tools.Switching states are developed for positive, negative and zero voltages as per the patterns given in the switching Table 1. The generated.

Power inverter. gate pulses are given to each switch in accordance with the developed pattern and thus the output is obtained.## In refrigeration compressors.An inverter can be used to control the speed of the compressor motor to drive variable refrigerant flow in a refrigeration or air conditioning system to regulate system performance. Such installations are known as inverter compressors. Traditional methods of refrigeration regulation use single-speed compressors switched on and off periodically; inverter-equipped systems have a variable-frequency drive that control the speed of the motor and thus the compressor and cooling output. The variable-frequency AC from the inverter drives a brushless or.

Power inverter. induction motor, the speed of which is proportional to the frequency of the AC it is fed, so the compressor can be run at variable speeds—eliminating compressor stop-start cycles increases efficiency. A microcontroller typically monitors the temperature in the space to be cooled, and adjusts the speed of the compressor to maintain the desired temperature. The additional electronics and system hardware add cost to the equipment, but can result in substantial savings in operating costs. The first inverter air conditioners were released by Toshiba in 1981, in Japan.## Power grid.Grid-tied inverters are designed to feed into the electric power distribution.

Power inverter. hundred megawatts, are used to deliver power from high voltage direct current transmission systems to alternating current distribution systems.## Solar.A solar inverter is a balance of system (BOS) component of a photovoltaic system and can be used for both grid-connected and off-grid systems. Solar inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection.Solar micro-inverters differ from conventional inverters, as an individual micro-inverter is attached to each solar panel. This can improve the overall efficiency of the system. The output from several micro-inverters is then combined and often fed to the electrical.

Power inverter. grid.In other applications, a conventional inverter can be combined with a battery bank maintained by a solar charge controller. This combination of components is often referred to as a solar generator.Solar inverters are also used in spacecraft photovoltaic system.## Induction heating.Inverters convert low frequency main AC power to higher frequency for use in induction heating. To do this, AC power is first rectified to provide DC power. The inverter then changes the DC power to high frequency AC power. Due to the reduction in the number of DC sources employed, the structure becomes more reliable and the output voltage has.

Power inverter. higher resolution due to an increase in the number of steps so that the reference sinusoidal voltage can be better achieved. This configuration has recently become very popular in AC power supply and adjustable speed drive applications. This new inverter can avoid extra clamping diodes or voltage balancing capacitors.There are three kinds of level shifted modulation techniques, namely: Phase Opposition Disposition (POD) Alternative Phase Opposition Disposition (APOD) Phase Disposition (PD)## HVDC power transmission.With HVDC power transmission, AC power is rectified and high voltage DC power is transmitted to another location. At the receiving location, an inverter in a static inverter.

Power inverter. plant converts the power back to AC. The inverter must be synchronized with grid frequency and phase and minimize harmonic generation.## Electroshock weapons.Electroshock weapons and tasers have a DC/AC inverter to generate several tens of thousands of V AC out of a small 9 V DC battery. First the 9 V DC is converted to 400–2000 V AC with a compact high frequency transformer, which is then rectified and temporarily stored in a high voltage capacitor until a pre-set threshold voltage is reached. When the threshold (set by way of an airgap or TRIAC) is reached, the capacitor dumps its.

Power inverter. entire load into a pulse transformer which then steps it up to its final output voltage of 20–60 kV. A variant of the principle is also used in electronic flash and bug zappers, though they rely on a capacitor-based voltage multiplier to achieve their high voltage.## Miscellaneous.Typical applications for power inverters include: Portable consumer devices that allow the user to connect a battery, or set of batteries, to the device to produce AC power to run various electrical items such as lights, televisions, kitchen appliances, and power tools. Use in power generation systems such as electric utility companies or solar.

Power inverter. generating systems to convert DC power to AC power. Use within any larger electronic system where an engineering need exists for deriving an AC source from a DC source. Frequency conversion - if a user in (say) a 50 Hz country needs a 60 Hz supply to power equipment that is frequency-specific, such as a small motor or some electronics, it is possible to convert the frequency by running an inverter with a 60 Hz output from a DC source such as a 12V power supply running from the 50 Hz mains.## Circuit description.## Basic design.In one simple inverter circuit,.

Power inverter. DC power is connected to a transformer through the center tap of the primary winding. A relay switch is rapidly switched back and forth to allow current to flow back to the DC source following two alternate paths through one end of the primary winding and then the other. The alternation of the direction of current in the primary winding of the transformer produces alternating current (AC) in the secondary circuit.The electromechanical version of the switching device includes two stationary contacts and a spring supported moving contact. The spring holds the movable contact against one of the stationary contacts and.

Power inverter. provide large power handling capability in a semiconductor device, and can readily be controlled over a variable firing range.The switch in the simple inverter described above, when not coupled to an output transformer, produces a square voltage waveform due to its simple off and on nature as opposed to the sinusoidal waveform that is the usual waveform of an AC power supply. Using Fourier analysis, periodic waveforms are represented as the sum of an infinite series of sine waves. The sine wave that has the same frequency as the original waveform is called the fundamental component. The other sine waves,.

Power inverter. car that is moving can turn into a source of energy and can, with the right inverter topology (full H-bridge) charge the car battery when decelerating or braking. In a similar manner, the right topology (full H-bridge) can invert the roles of "source" and "load", that is, if for example the voltage is higher on the AC "load" side (by adding a solar inverter, similar to a gen-set, but solid state), energy can flow back into the DC "source" or battery.Based on the basic H-bridge topology, there are two different fundamental control strategies called basic frequency-variable bridge converter and PWM.

Power inverter. control. Here, in the left image of H-bridge circuit, the top left switch is named as "S1", and others are named as "S2, S3, S4" in counterclockwise order.For the basic frequency-variable bridge converter, the switches can be operated at the same frequency as the AC in the electric grid. However, it is the rate at which the switches open and close that determines the AC frequency. When S1 and S4 are on and the other two are off, the load is provided with positive voltage and vice versa. We could control the on-off states of the switches to adjust the.

Power inverter. AC magnitude and phase. We could also control the switches to eliminate certain harmonics. This includes controlling the switches to create notches, or 0-state regions, in the output waveform or adding the outputs of two or more converters in parallel that are phase shifted in respect to one another.Another method that can be used is PWM. Unlike the basic frequency-variable bridge converter, in the PWM controlling strategy, only two switches S3, S4 can operate at the frequency of the AC side or at any low frequency. The other two would switch much faster (typically 100 KHz) to create square voltages.

Power inverter. level of distortion caused by harmonics. The waveform quality of AC produced directly by H-bridge mentioned above would be not as good as we want.The issue of waveform quality can be addressed in many ways. Capacitors and inductors can be used to filter the waveform. If the design includes a transformer, filtering can be applied to the primary or the secondary side of the transformer or to both sides. Low-pass filters are applied to allow the fundamental component of the waveform to pass to the output while limiting the passage of the harmonic components. If the inverter is designed to.

Power inverter. provide power at a fixed frequency, a resonant filter can be used. For an adjustable frequency inverter, the filter must be tuned to a frequency that is above the maximum fundamental frequency.Since most loads contain inductance, feedback rectifiers or antiparallel diodes are often connected across each semiconductor switch to provide a path for the peak inductive load current when the switch is turned off. The antiparallel diodes are somewhat similar to the "freewheeling diodes" used in AC/DC converter circuits.Fourier analysis reveals that a waveform, like a square wave, that is anti-symmetrical about the 180 degree point contains only odd harmonics,.

Power inverter. simplifies the electronics, but the inductors and capacitors tend to be large and heavy. Its high efficiency makes this approach popular in large uninterruptible power supplies in data centers that run the inverter continuously in an "online" mode to avoid any switchover transient when power is lost.A closely related approach uses a ferroresonant transformer, also known as a constant voltage transformer, to remove harmonics and to store enough energy to sustain the load for a few AC cycles. This property makes them useful in standby power supplies to eliminate the switchover transient that otherwise occurs during a power failure while.

Power inverter. size and volume. In 2014, Google together with IEEE started an open competition named Little Box Challenge, with a prize money of $1,000,000, to build a (much) smaller power inverter.## History.## Early inverters.From the late nineteenth century through the middle of the twentieth century, DC-to-AC power conversion was accomplished using rotary converters or motor-generator sets (M-G sets). In the early twentieth century, vacuum tubes and gas-filled tubes began to be used as switches in inverter circuits. The most widely used type of tube was the thyratron.The origins of electromechanical inverters explain the source of the term "inverter". Early AC-to-DC converters.

Power inverter. used an induction or synchronous AC motor direct-connected to a generator (dynamo) so that the generator's commutator reversed its connections at exactly the right moments to produce DC. A later development is the synchronous converter, in which the motor and generator windings are combined into one armature, with slip rings at one end and a commutator at the other and only one field frame. The result with either is AC-in, DC-out. With an M-G set, the DC can be considered to be separately generated from the AC; with a synchronous converter, in a certain sense it can be considered to.

Power inverter. be "mechanically rectified AC". Given the right auxiliary and control equipment, an M-G set or rotary converter can be "run backwards", converting DC to AC. Hence an inverter is an inverted converter.## Controlled rectifier inverters.Since early transistors were not available with sufficient voltage and current ratings for most inverter applications, it was the 1957 introduction of the thyristor or silicon-controlled rectifier (SCR) that initiated the transition to solid state inverter circuits.The "commutation" requirements of SCRs are a key consideration in SCR circuit designs. SCRs do not turn off or "commutate" automatically when the gate control signal is shut off. They.

Power inverter. only turn off when the forward current is reduced to below the minimum holding current, which varies with each kind of SCR, through some external process. For SCRs connected to an AC power source, commutation occurs naturally every time the polarity of the source voltage reverses. SCRs connected to a DC power source usually require a means of forced commutation that forces the current to zero when commutation is required. The least complicated SCR circuits employ natural commutation rather than forced commutation. With the addition of forced commutation circuits, SCRs have been used in the types of inverter circuits described.

Power inverter. above.In applications where inverters transfer power from a DC power source to an AC power source, it is possible to use AC-to-DC controlled rectifier circuits operating in the inversion mode. In the inversion mode, a controlled rectifier circuit operates as a line commutated inverter. This type of operation can be used in HVDC power transmission systems and in regenerative braking operation of motor control systems.Another type of SCR inverter circuit is the current source input (CSI) inverter. A CSI inverter is the dual of a six-step voltage source inverter. With a current source inverter, the DC power supply is configured.

Power inverter. as a current source rather than a voltage source. The inverter SCRs are switched in a six-step sequence to direct the current to a three-phase AC load as a stepped current waveform. CSI inverter commutation methods include load commutation and parallel capacitor commutation. With both methods, the input current regulation assists the commutation. With load commutation, the load is a synchronous motor operated at a leading power factor.As they have become available in higher voltage and current ratings, semiconductors such as transistors or IGBTs that can be turned off by means of control signals have become the preferred switching components.

Power inverter. for use in inverter circuits.## Rectifier and inverter pulse numbers.Rectifier circuits are often classified by the number of current pulses that flow to the DC side of the rectifier per cycle of AC input voltage. A single-phase half-wave rectifier is a one-pulse circuit and a single-phase full-wave rectifier is a two-pulse circuit. A three-phase half-wave rectifier is a three-pulse circuit and a three-phase full-wave rectifier is a six-pulse circuit.With three-phase rectifiers, two or more rectifiers are sometimes connected in series or parallel to obtain higher voltage or current ratings. The rectifier inputs are supplied from special transformers that provide phase.

Power inverter. shifted outputs. This has the effect of phase multiplication. Six phases are obtained from two transformers, twelve phases from three transformers and so on. The associated rectifier circuits are 12-pulse rectifiers, 18-pulse rectifiers and so on...When controlled rectifier circuits are operated in the inversion mode, they would be classified by pulse number also. Rectifier circuits that have a higher pulse number have reduced harmonic content in the AC input current and reduced ripple in the DC output voltage. In the inversion mode, circuits that have a higher pulse number have lower harmonic content in the AC output voltage waveform.## Other.

Clitocybe nuda. Clitocybe nuda, commonly known as the wood blewit and alternately described as Lepista nuda, is an edible mushroom native to Europe and North America. Described by Pierre Bulliard in 1790, it was also known as "Tricholoma nudum" for many years. It is found in both coniferous and deciduous woodlands. It is a fairly distinctive mushroom that is widely eaten, though there is some caution about edibility. Nevertheless, it has been cultivated in Britain, the Netherlands and France.## Taxonomy and naming.The French mycologist Pierre Bulliard described the wood blewit in his work "Herbier de la France" in 1790 as "Agaricus nudus",.

Clitocybe nuda. found some in Ovenden.German mycologist Paul Kummer placed it in the genus "Tricholoma" in 1871, the same year that English botanist Mordecai Cubitt Cooke placed it in "Lepista". It was known by these names for many years, with some authors accepting "Lepista" and while others retained the wood blewit in "Tricholoma". In 1969 Howard E. Bigelow and Alexander H. Smith reviewed "Lepista" and reclassified it as a subgenus of "Clitocybe" Finnish mycologist Harri Harmaja has called for the sinking of "Lepista" into "Clitocybe", with "C. nebularis" as the type species of the latter genus. Hence the wood blewit is classified.

Clitocybe nuda. as either "Lepista nuda" or "Clitocybe nuda".A 2015 genetic study found that the genera "Collybia" and "Lepista" were closely related to the core clade of "Clitocybe", but that all three were polyphyletic, with many members in lineages removed from other members of the same genus and instead more closely related to the other two. To complicate matters, the wood blewit is not closely related to the type species of "Lepista", "L. densifolia". Alvarado and colleagues declined to define the genera but proposed several options and highlighted the need for a wider analysis.The species is commonly known as the wood blewit.

In Australia it has developed a relationship with some eucalyptus species and gorse; with an entirely different growth pattern and differs slightly in appearance to its European Lepista Nuda cousins. It is commonly referred to as "the purple nudist mushroom", a name coined by Australian Free Food Forager Ingrid Button in 2016.It is a saprotrophic species, growing on decaying.

Lantana camara. Lantana camara (common lantana) is a species of flowering plant within the verbena family (Verbenaceae), native to the American tropics. It is a very adaptable species, which can inhabit a wide variety of ecosystems; once it has been introduced into a habitat it spreads rapidly; between 45ºN and 45ºS and more than 1400 (m) in altitude.It has spread from its native range to around 50 countries, where it has become an invasive species. It first spread out of the Americas when it was brought to Europe by Dutch explorers and cultivated widely, soon spreading further into Asia and Oceania where.

Lantana camara. it has established itself as a notorious weed, and in Goa it was introduced by the Portuguese."L. camara" can outcompete native species, leading to a reduction in biodiversity. It can also cause problems if it invades agricultural areas as a result of its toxicity to livestock, as well as its ability to form dense thickets which, if left unchecked, can greatly reduce the productivity of farmland.## Description."Lantana camara" is a perennial, erect sprawling or scandent, shrub which typically grows to around 2 (m) tall and form dense thickets in a variety of environments. Under the right conditions, it can scramble.

Lantana camara. up into trees and can grow to 6 (m) tall.The leaves are broadly ovate, opposite, and simple and have a strong odour when crushed."L. camara" has small tubular-shaped flowers, which each have four petals and are arranged in clusters in terminal areas stems. Flowers come in many different colours, including red, yellow, white, pink and orange, which differ depending on location in inflorescences, age, and maturity. The flower has a tutti frutti smell with a peppery undertone. After pollination occurs, the colour of the flowers changes (typically from yellow to orangish, pinkish, or reddish); this is believed to be a.

Lantana camara. signal to pollinators that the pre-change colour contains a reward as well as being sexually viable, thus increasing pollination efficiency. In frost-free climates the plant can bloom all year round, especially when the soil is moist.There are five major flower colour varieties in Australia: "Pink" – Bud: pink; Middle ring: yellow opening with pale yellow petals; Outer ring: orange opening with pale or dark pink petals "White" – Bud: cream coloured; Middle ring: yellow opening with light yellow petals; Outer ring: orange or yellow opening with lilac petals "Pink-edged Red" – Bud: pink to reddish pink; Middle ring: orange opening.

Lantana camara. with light yellow to orange petals; Outer ring: orange opening having two pink to red petals "Red" – Bud: blood red; Middle ring: yellow opening with yellow petals; Outer ring: red throat having red petals "Orange" – Bud: orange; Middle ring: yellow to orange opening, yellow petals; Outer ring: orange opening with orange petalsThe fruit is a berry-like drupe which turns from green to dark purple when mature. Green unripe fruits are inedible to humans and animals alike. Because of dense patches of hard spikes on their rind, ingestion of them can result in serious damage to the digestive tract.

Lantana camara. Both seed and vegetative reproduction occur. Up to 12,000 fruits can be produced by each plant.## Taxonomy.Due to extensive selective breeding throughout the 17th and 18th centuries for use as an ornamental plant, there are now many different cultivars.Other common names include Cariaquillo (Boriken, Puerto Rico), Spanish flag, big-sage (Malaysia), Putush (West Bengal), Kongini (Kerala), wild-sage, red-sage, white-sage (Caribbean), korsu wiri or korsoe wiwiri (Suriname), tickberry (South Africa), Kashi Kothan (Maldives), West Indian lantana, umbelanterna, and Gu Phool in Assam, and Thirei in Manipur.## Etymology.The name "Lantana" derives from the Latin name of the wayfaring tree "Viburnum lantana", the flowers.

Lantana camara. of which closely resemble "Lantana"."Camara" is derived from Greek, meaning 'arched', 'chambered', or 'vaulted'.## Distribution and habitat.The native range of "Lantana camara" is Central and South America; however, it has become naturalised in around 60 tropical and sub-tropical countries worldwide. It is found frequently in east and southern Africa, where it occurs at altitudes below 2000 (m), and often invades previously disturbed areas such as logged forests and areas cleared for agriculture."L. camara" has also spread across the areas of Africa, Southern Europe, such as Spain and Portugal, and also the Middle East, India, tropical Asia, Australia, New Zealand, and.

Lantana camara. the US, as well as many Atlantic, Pacific and Indian Ocean islands. It has become a significant weed in Sri Lanka after escaping from the Royal Botanical Gardens in 1926. Lantanas were brought to Australia as an ornamental garden plant in 1841, which spread and escaped domestic cultivation and became established in the wild within 20 years. They were brought to India by the British around 200 years ago, which then spread and became invasive there as well.It was introduced into the Philippines from Hawaii as part of an exchange program between the United States and the Philippines; however, it.

Lantana camara. managed to escape and has become naturalized in the islands. It has also been introduced to the whole southern US, from California to North Carolina, and is considered hardy in US Department of Agriculture zones 10 and 11.The range of "L. camara" is still increasing, shown by the fact that it has invaded many islands on which it was not present in 1974, including the Galapagos Islands, Saipan and the Solomon Islands. There is also evidence that "L. camara" is still increasing its range in areas where it has been established for many years, such as East Africa, Australia and.

Lantana camara. New Zealand. The ability of "L. camara" to rapidly colonise areas of land which have been disturbed has allowed it to proliferate in countries where activities such as logging, clearance for agriculture and forest fires are common. In contrast, in countries with large areas of intact primary forest, the distribution of "L. camara" has been limited.## Ecology.Birds and other animals eat the seeds, helping spread them over large distances.## Habitat.The species is found in a variety of environments, including: Agricultural areas Forest margins and gaps Riparian zones Grasslands Secondary forest, and Beach fronts."L. camara" is rarely found in natural or.

Lantana camara. semi-natural areas of forest, as it is unable to compete with taller trees due to its lack of tolerance for shade. Instead it grows at the forest edge. "L. camara" can survive in a wide range of climatic conditions, including drought, different soil types, heat, humidity and salt. It is also relatively fire tolerant and can quickly establish itself in recently burnt areas of forest.## As an invasive species."L. camara" is considered to be a weed in large areas of the Paleotropics where it has established itself. In agricultural areas or secondary forests it can become the dominant understorey shrub,.

Lantana camara. crowding out other native species and reducing biodiversity. The formation of dense thickets of "L. camara" can significantly slow down the regeneration of forests by preventing the growth of new trees.In the US, "L. camara" is considered invasive in tropical areas such as Florida and Hawaii.Although "L. camara" is itself quite resistant to fire, it can change fire patterns in a forest ecosystem by altering the fuel load, causing a buildup of forest fuel, which itself increases the risk of fires spreading to the canopy. This can be particularly destructive in dry, arid areas where fire can spread quickly and.

Lantana camara. lead to the loss of large areas of natural ecosystem."L. camara" reduces the productivity in pasture through the formation of dense thickets, which reduce growth of crops as well as make harvesting more difficult. There are also secondary impacts, including the finding that in Africa, mosquitos which transmit malaria and tsetse flies shelter within the bushes of "L. camara".Even though "L. camara" is considered invasive to the Western Ghats, the plant does not seem to impact biodiversity in the region; rather it tends to simply occupy the same moist regions as other species.There are many reasons why "L. camara" has.

Lantana camara. been so successful as an invasive species; however, the primary factors which have allowed it to establish itself are: Wide dispersal range made possible by birds and other animals that eat its drupes Less prone to being eaten by animals due to toxicity Tolerance of a wide range of environmental conditions Increase in logging and habitat modification, which has been beneficial to "L. camara" as it prefers disturbed habitats Production of toxic chemicals which inhibit competing plant species Extremely high seed production (12,000 seeds from each plant per year)## Management and control.Effective management of invasive "L. camara" in the long.

Lantana camara. term will require a reduction in activities that create degraded habitats. Maintaining functioning (healthy) ecosystems is key to preventing invasive species from establishing themselves and out-competing native fauna and flora.## Biological.Insects and other biocontrol agents have been implemented with varying degrees of success in an attempt to control "L. camara". It was the first weed ever subjected to biological control; however, none of the programs have been successful despite 36 control agents being used across 33 regions.The lack of success using biological control in this case is most likely due to the many hybrid forms of "L. camara", as well.

Lantana camara. as its large genetic diversity which makes it difficult for the control agents to target all plants effectively. A recent study in India has shown some results around biological control of this plant using tingid bugs.## Mechanical.Mechanical control of "L. camara" involves physically removing the plants. Physical removal can be effective but is labour-intensive and expensive, therefore removal is usually only appropriate in small areas or at the early stages of an infestation. Another method of mechanical control is to use fire treatment, followed by revegetation with native species.## Chemical.Using herbicides to manage "L. camara" is very effective but also.

Lantana camara. expensive, prohibiting its use in many poorer countries where "L. camara" is well established. The most effective way of chemically treating plant species is to first mow the area, then spray the area with a weed-killer, although this may have serious environmental consequences.## Toxicity."Lantana camara" is known to be toxic to livestock such as cattle, sheep, horses, dogs and goats. The active substances causing toxicity in grazing animals are pentacyclic triterpenoids, which result in liver damage and photosensitivity. "L. camara" also excretes allelopathic chemicals, which reduce the growth of surrounding plants by inhibiting germination and root elongation.The toxicity of "L.

Lantana camara. camara" to humans is undetermined, with several studies suggesting that ingesting berries can be toxic to humans, such as a study by O. P. Sharma which states "Green unripe fruits of the plant are toxic to humans". North Carolina State University's Extension Gardener website states that ingestion of the flowers, fruits, and leaves can cause vomiting, diarrhea, difficulty breathing, and liver failure, while the leaves can cause contact dermatitis. A field guide by the US Department of the Army says the plant can even be fatal. Contrarily, some studies have claimed that the species poses no risk to humans when.

Lantana camara. eaten, and is in fact edible when ripe.## Uses."Lantana camara" stalks have been used in the construction of furniture, such as chairs and tables; however, the main uses have historically been medicinal and ornamental.## Medicinal value.Studies conducted in India have found that "Lantana" leaves can display antimicrobial, fungicidal and insecticidal properties. "L. camara" has also been used in traditional herbal medicines for treating a variety of ailments, including cancer, skin itches, leprosy, chicken pox, measles, asthma and ulcers."L. camara" extract has shown to reduce gastric ulcer development in rats.## Ornamental."Lantana camara" has been grown specifically for use as an ornamental.

Lantana camara. plant since Dutch explorers first brought it to Europe from the New World. Its ability to last for a relatively long time without water, and the fact that it does not have many pests or diseases which affect it, have contributed to it becoming a common ornamental plant. "L. camara" also attracts butterflies and birds and is frequently used in butterfly gardens. As an ornamental, "L. camara" is often cultivated indoors, or in a conservatory, in cool climates, but can also thrive in a garden with sufficient shelter.## As a host plant.Many butterfly species feed on the nectar of "L.

Lantana camara. camara." "Papilio homerus", the largest butterfly in the western hemisphere, is known to feed on the nectar of the flowers as an opportunistic flower feeder. A jumping spider, "Evarcha culicivora", has an association with "L. camara". They consume the nectar for food and preferentially use these plants as a location for courtship.

Ipomoea nil. Ipomoea nil is a species of "Ipomoea" morning glory known by several common names, including picotee morning glory, ivy morning glory, and Japanese morning glory (although it is not native to Japan). It is native to the tropical Americas, and has been introduced widely across the world.## Description.Native to Central America and Mexico, the plant is a climber with twining stems up to 5 m long and is dense to scattered with long hairy trichomes. The finely hairy, emerald green leaves are ovate to almost circular, 5 to 14 cm long. The base is heart-shaped, the edge is entire or.

Ipomoea nil. lobed three to five times, the leaf lobes are pointed or tapering. The leaves are very similar to those of "Ipomoea hederacea".The funnel-shaped, colorful flowers (blue to reddish-purple, with whitish tube) are quite showy and are individually up to five in often dense cymose groups, in which fully developed flowers and developing buds stand together. The wild forms are smaller than cultivated forms, and are almost always blue; the cultivated forms come in a wide variety of colors. They open in the morning and close by the afternoon. The long, thorny hairy sepals have a length of 15 to 25.

Ipomoea nil. mm, they are long, lanceolate, and have a linear-lanceolate tip. The crown is blue, purple, or almost scarlet red. The throat is often colored white. The crown tube has a length of 3 to 5 cm, the crown hem has a width of 4 to 5 cm.The fruits are almost spherical to spherical capsule fruits with a diameter of 8 to 12 mm. The seeds are pear-shaped and densely covered with short trichomes.## Cultivation.It is cultivated as an ornamental plant in many places, and the descendants of garden escapees now grow wild. Fast-growing and self-seeding, it may used to hide.

Ipomoea nil. unsightly fences or walls, and may also be used decoratively on trellises. The flowers are several centimeters wide and appear in various shades of blue, pink or rose, often with white stripes or edges or blends of colors. Common cultivars include 'Scarlet O'Hara', 'Early Call', and 'Rose Silk'.Hybrids, for instance with "I. purpurea", have been developed. Some of these have been given the name "I. x imperialis" (Imperial Japanese morning glory), which is not official. Cultivars include 'Sunrise Serenade'. Alternative nomenclatures include "Ipomoea nil x imperialis", as in 'Cameo Elegance', or "Ipomoea nil' 'Imperialis'. It is a frost tender annual.

Ipomoea nil. in colder areas or if placed in shaded area in the garden, but can be kept as a perennial if it is well managed and placed in full sun during the winter.## Morning glories in Japan.Morning glories are popular in Japan. They are believed to have been introduced there directly from China in the Heian period of the 8th to 9th centuries. During the Edo period of the 17th to 19th centuries, as more people started to live in cities, a fad for growing potted morning glories of different colors and sizes swept through the country. The pots are often.

Ipomoea nil. equipped with cylindrical structures called "andon shitate" (), which look like Japanese lanterns at night.In early summer, morning glory markets are held in large cities in Japan, where merchants and hobbyists sell the flowers.
