Callistemon Citrinus
''Melaleuca citrina'', the common red bottlebrush, crimson bottlebrush, or lemon bottlebrush, is a plant in the myrtle family Myrtaceae, and is endemic to eastern Australia. Some Australian state herbaria continue to use the name ''Callistemon citrinus''. It is a hardy and adaptable species, common in its natural habitat. It is widely cultivated, not only in Australia. It was one of the first Australian plants to be grown outside the country, having been taken to England in 1770 by Joseph Banks. Its showy red flower spikes, present over most of the year in an ideal situation, account for its popularity. Description ''Melaleuca citrina'' is a shrub growing to tall but more usually in the range high and wide. It has hard, fibrous or papery bark and its young growth is usually covered with soft, silky hairs. Its leaves are arranged alternately and are long, wide, hard, flat, narrow egg-shaped with the narrower end near the base and with a pointed but not sharp end. There are b ...

William Curtis
William Curtis (11 January 1746 – 7 July 1799) was an English botanist and entomologist, who was born at Alton, Hampshire, site of the Curtis Museum. Curtis began as an apothecary, before turning his attention to botany and other natural history. The publications he prepared reached a wider audience than early works on the subject had intended. At the age of 25 he produced ''Instructions for collecting and preserving insects; particularly moths and butterflies''. Curtis was demonstrator of plants and Praefectus Horti at the Chelsea Physic Garden from 1771 to 1777. He established his own London Botanic Garden at Lambeth in 1779, moving to Brompton in 1789. He published ''Flora Londinensis'' (6 volumes, 1777–1798), a pioneering work in that it devoted itself to urban nature. Financial success was not found, but he went on the publish ''The Botanical Magazine'' in 1787, a work that would also feature hand coloured plates by artists such as James Sowerby and Sydenham Edwards. ...

Blue Mountains (New South Wales)
The Blue Mountains are a mountainous region and a mountain range located in New South Wales, Australia. The region borders on Sydney's metropolitan area, its foothills starting about west of centre of the state capital, close to Penrith on the outskirts of Greater Sydney region. The public's understanding of the extent of the Blue Mountains is varied, as it forms only part of an extensive mountainous area associated with the Great Dividing Range. As defined in 1970, the Blue Mountains region is bounded by the Nepean and Hawkesbury rivers in the east, the Coxs River and Lake Burragorang to the west and south, and the Wolgan and Colo rivers to the north. Geologically, it is situated in the central parts of the Sydney Basin. The ''Blue Mountains Range'' comprises a range of mountains, plateau escarpments extending off the Great Dividing Range about northwest of Wolgan Gap in a generally southeasterly direction for about , terminating at . For about two-thirds of its len ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Horticultural Society
The Royal Horticultural Society (RHS), founded in 1804 as the Horticultural Society of London, is the UK's leading gardening charity. The RHS promotes horticulture through its five gardens at Wisley (Surrey), Hyde Hall (Essex), Harlow Carr (North Yorkshire), Rosemoor (Devon) and Bridgewater (Greater Manchester); flower shows including the Chelsea Flower Show, Hampton Court Palace Flower Show, Tatton Park Flower Show and Cardiff Flower Show; community gardening schemes; Britain in Bloom and a vast educational programme. It also supports training for professional and amateur gardeners. the president was Keith Weed and the director general was Sue Biggs CBE. History Founders The creation of a British horticultural society was suggested by John Wedgwood (son of Josiah Wedgwood) in 1800. His aims were fairly modest: he wanted to hold regular meetings, allowing the society's members the opportunity to present papers on their horticultural activities and discoveries, to enc ...

Callistemon 'Splendens'
''Callistemon'' 'Splendens' is a commonly grown cultivar of the plant genus'' Callistemon''. It has a compact and rounded habit and usually grows to about high and wide, although it may grow taller. Large, well-displayed "brushes" are produced in late spring, with further flowering sometimes occurring at other times. New growth is pink-tinged and the leaves are elliptic and up to 90 mm long and 20 mm wide. The cultivar, which has been in grown for many years, is of uncertain origin. It was originally known as ''Callistemon citrinus'' var. ''splendens'', first formally described in 1925 in ''Botanical Magazine''. In 1970 it was promoted under the name 'Endeavour' to mark the bicentennial of James Cook's voyage to Australia on the '' Endeavour''. It was registered under the name ''Callistemon'' 'Splendens' with the Australian Cultivar Registration Authority in 1989. This plant has gained the Royal Horticultural Society's Award of Garden Merit The Award of Garden Merit (A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cutting (plant)
A plant cutting is a piece of a plant that is used in horticulture for vegetative (asexual) propagation. A piece of the stem or root of the source plant is placed in a suitable medium such as moist soil. If the conditions are suitable, the plant piece will begin to grow as a new plant independent of the parent, a process known as striking. A stem cutting produces new roots, and a root cutting produces new stems. Some plants can be grown from leaf pieces, called leaf cuttings, which produce both stems and roots. The scions used in grafting are also called cuttings. Propagating plants from cuttings is an ancient form of cloning. There are several advantages of cuttings, mainly that the produced offspring are practically clones of their parent plants. If a plant has favorable traits, it can continue to pass down its advantageous genetic information to its offspring. This is especially economically advantageous as it allows commercial growers to clone a certain plant to ensure consis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Syon House
Syon House is the west London residence of the Duke of Northumberland. A Grade I listed building, it lies within the 200-acre (80 hectare) Syon Park, in the London Borough of Hounslow. The family's traditional central London residence had been Northumberland House, now demolished. The eclectic interior of Syon House was designed by the architect Robert Adam in the 1760s. History Syon House derives its name from Syon Abbey, a medieval monastery of the Bridgettine Order, founded in 1415 on a nearby site by King Henry V. The abbey moved to the site now occupied by Syon House in 1431. It was one of the wealthiest nunneries in the country and a local legend recites that the monks of Sheen had a ley tunnel running to the nunnery at Syon.Westwood, Jennifer (1985), ''Albion. A Guide to Legendary Britain.'' Pub. Grafton Books, London. . p. 126. In 1539, the abbey was closed by royal agents during the Dissolution of the Monasteries and the monastic community was expelled.

Leptospermone
Leptospermone is a chemical compound (a β-triketone) produced by some members of the myrtle family ('' Myrtaceae''), such as '' Callistemon citrinus'' (Lemon Bottlebrush), a shrub native to Australia, and ''Leptospermum scoparium'' (Manuka), a New Zealand tree from which it gets its name. Modification of this allelopathic chemical to produce mesotrione led to the commercialization of derivative compounds as HPPD inhibitor herbicides. History Leptospermone was first identified in 1927 and was extracted from a variety of plants in 1965, 1966 and 1968. It was first identified as a chemical in ''Callistemon citrinus'' in California in 1977. A biologist at the Western Research Centre of Stauffer Chemical Company noticed that very few plants grew under ''Callistemon citrinus'' bushes. After taking soil samples and creating an array of extracts, one was identified as an herbicide. While it did have herbicidal effects, the rate required for sufficient coverage was too high to be of prac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mesotrione
Mesotrione is the ISO common name for an organic compound that is used as a selective herbicide, especially in maize. A synthetic inspired by the natural substance leptospermone, it inhibits the enzyme 4-hydroxyphenylpyruvate dioxygenase (HPPD) and is sold under brand names including Callisto and Tenacity. It was first marketed by Syngenta in 2001. History The invention of the triketone class of herbicides had its beginnings in an observation in 1977 of allelopathic weed control near a bottlebrush tree, '' Callistemon citrinus''. Chemists at the Stauffer Chemical Company identified the compound responsible as leptospermone, a known natural product which had not previously been reported as having biological activity. Extensive work on analogues led to the discovery and development of sulcotrione and mesotrione. The triketone herbicides were found to be effective on a wide range of commercially-important weed species and to have both pre- and post-emergence activity. M ...

Crimson Rosella
The crimson rosella (''Platycercus elegans'') is a parrot native to eastern and south eastern Australia which has been introduced to New Zealand and Norfolk Island. It is commonly found in, but not restricted to, mountain forests and gardens. The species as it now stands has subsumed two former separate species, the yellow rosella and the Adelaide rosella. Molecular studies show one of the three red-coloured races, ''P. e. nigrescens'', is genetically more distinct. Taxonomy The crimson rosella was described by Johann Friedrich Gmelin in the 13th edition of ''Systema Naturae'' in 1788 as ''Psittacus elegans''. The binomial name had been used by Clusius to describe the hawk-headed parrot in 1605, however this predates the start of Linnean taxonomy. The crimson rosella had been described and named by John Latham in 1781 as the "Beautiful Lory", from a specimen in the collection of Sir Joseph Banks, and then as the "Pennantian Parrot" in 1787 in honour of Thomas Pennant.

Silvereye
The silvereye or wax-eye (''Zosterops lateralis'') is a very small omnivorous passerine bird of the south-west Pacific. In Australia and New Zealand its common name is sometimes white-eye, but this name is more commonly used to refer to all members of the genus ''Zosterops'', or the entire family Zosteropidae. In New Zealand, the silvereye was first recorded in 1832. It arrived in greater numbers in 1856, and it is assumed that a migrating flock was swept eastwards by a storm. As an apparently self-introduced bird it is protected as a native New Zealand species. Its Māori name, , means "stranger" or more literally, "new arrival". Taxonomy The silvereye was first described by the English ornithologist John Latham in 1801 under the binomial name ''Sylvia lateralis''. There are 17 subspecies: * ''Z. l. chlorocephalus'' A. J. Campbell & S. A. White, 1910 (Capricorn silvereye)– Capricorn and Bunker Group, central Queensland, Australia * ''Z. l. chloronotus'' Gould, 1841 ( western ...

Red Wattlebird
The red wattlebird (''Anthochaera carunculata'') is a passerine bird native to southern Australia. At in length, it is the second largest species of Australian honeyeater. It has mainly grey-brown plumage, with red eyes, distinctive pinkish-red wattles on either side of the neck, white streaks on the chest and a large bright yellow patch on the lower belly. The sexes are similar in plumage. Juveniles have less prominent wattles and browner eyes. John White described the red wattlebird in 1790. Three subspecies are recognized. The species is found in southeast Queensland, New South Wales, Victoria, South Australia and southwest Western Australia in open forest and woodlands, and is a common visitor to urban gardens and parks. Loud and conspicuous, the red wattlebird is generally found in trees, where it gets most of its food; occasionally it forages on the ground. It is one of the largest nectarivorous birds in the world, feeding from a wide variety of flowering plants. Insect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
