Kingia
''Kingia'' is a genus consisting of a single species, ''Kingia australis'', and belongs to the plant family Dasypogonaceae. The Aboriginal name bullanock is used as a common name for the plant. It has a thick pseudo-trunk consisting of accumulated leaf-bases, with a cluster of long, slender leaves on top. The trunk is usually unbranched, but can branch if the growing tip is damaged. Flowers occur in egg-shaped clusters on the ends of up to 100 long curved stems. ''Kingia'' grows extremely slowly, the trunk increasing in height by about 1½ centimetres per year. It can live for centuries, however, so can attain a substantial height; 400-year-old plants with a height of six metres are not unusual. Taxonomy When not flowering, ''Kingia australis'' bear a superficial similarity to species of the genus ''Xanthorrhoea''. However, the flower stalks of ''Kingia australis'' are completely different from that of ''Xanthorrhoea'' species and the two are not closely related. For examp ...

Character And Description Of Kingia
''Character and description of Kingia, a new genus of plants found on the south-west coast of New Holland, with observations on the structure of its unimpregnated ovulum, and on the female flower of Cycadeae and Coniferae'' is an 1826 paper by botanist Robert Brown. Though nominally a formal description of the then-unpublished genus '' Kingia'', it is more notable for its digressions into ovule anatomy and development, in which Brown sets out for the first time the modern understanding of the structure of angiosperm ovules, and publishes the first description of the fundamental difference between angiosperms and gymnosperms. Of the latter it has been said that "no more important discovery was ever made in the domain of comparative morphology and systematic Botany". Background Brown had known of '' Kingia'' for many years, having collected specimens himself in 1800. However early specimens lacked good fruiting material, rendering it impossible to determine its systematics, so n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dasypogonaceae
Dasypogonaceae is a family of flowering plants, one that has not been commonly recognized by taxonomists; the plants it contains were usually included in the family Xanthorrhoeaceae. If valid, Dasypogonaceae includes four genera with 16 species. The 2016 APG IV system places the family in the order Arecales, after several studies revealed the family as a sister-family to Arecaceae. The earlier APG III (2009), APG II (2003), and the 1998 APG system all accepted the validity of the family, assigning it to the clade commelinids, but leaving it unplaced as to order. The commelinids are monocots, the broad group to which, in any event, these plant clearly belong. The family is endemic to Australia, and comprises 16 species in four genera. The best known representative is ''Kingia australis ''Kingia'' is a genus consisting of a single species, ''Kingia australis'', and belongs to the plant family Dasypogonaceae.

William Westall
William Westall (12 October 1781 – 22 January 1850) was a British landscape artist best known as one of the first artists to work in Australia. Early life Westall was born in Hertford and grew up in London, mostly Sydenham and Hampstead. The son of brewery manager Benjamin Westall (d.1794) and his second wife Martha ''née'' Harbord, William Westall had four step-siblings, the eldest of whom, Richard Westall, was a reputable painter and illustrator. William was interested in painting from a young age; Rienitz and Rienitz (1963) suggest that he looked up to his half-brother, and was ambitious to follow in his footsteps. There is evidence to suggest that Westall's parents did not support this career choice; however Richard became head of the family upon the death of Benjamin Westall in March 1794, and must have approved Westall's artistic ambitions, as from that time forward William Westall was given a thorough art education. At the age of sixteen he won a silver palette in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Australian Herbarium
The Western Australian Herbarium is the State Herbarium in Perth, Western Australia. It is part of the State government's Department of Parks and Wildlife, and has responsibility for the description and documentation of the flora of Western Australia. It has the Index Herbariorum code of PERTH. The Hebarium forms part of the Australasian Virtual Herbarium. The Herbarium is linked to the Western Australian 'Regional Herbaria Network' – which links approximately 84 regional community groups which have local reference collections. In 2000, with the Wildflower Society of Western Australia and the Botanic Gardens and Parks Authority it published '' The Western Australian Flora – A Descriptive Catalogue''. History The Herbarium was formed as the amalgamation of three separate government department herbaria: those of the Western Australian Museum, the Department of Agriculture, and the "forest herbarium" maintained by the Conservator of Forests. The first of these was formed by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert Brown (botanist, Born 1773)
Robert Brown (21 December 1773 – 10 June 1858) was a Scottish botanist and paleobotanist who made important contributions to botany largely through his pioneering use of the microscope. His contributions include one of the earliest detailed descriptions of the cell nucleus and cytoplasmic streaming; the observation of Brownian motion; early work on plant pollination and fertilisation, including being the first to recognise the fundamental difference between gymnosperms and angiosperms; and some of the earliest studies in palynology. He also made numerous contributions to plant taxonomy, notably erecting a number of plant families that are still accepted today; and numerous Australian plant genera and species, the fruit of his exploration of that continent with Matthew Flinders. Early life Robert Brown was born in Montrose on 21 December 1773, in a house that existed on the site where Montrose Library currently stands. He was the son of James Brown, a minister in the ...

Xanthorrhoea
''Xanthorrhoea'' () is a genus of about 30 species of flowering plants endemic to Australia. Species are known by the name grass tree. Description All are perennials and have a secondary thickening meristem in the stem. Many, but not all, species develop an above ground stem. The stem may take up to twenty years to emerge. Plants begin as a crown of rigid grass-like leaves, the caudex slowly growing beneath. The main stem or branches continue to develop beneath the crown, This is rough-surfaced, built from accumulated leaf-bases around the secondarily thickened trunk. The trunk is sometimes unbranched, some species will branch if the growing point is damaged, and others naturally grow numerous branches. Flowers are borne on a long spike above a bare section called a scape; the total length can be over three four metres long in some species. Flowering occurs in a distinct flowering period, which varies for each species, and often stimulated by bushfire. Fires will burn the le ...

Angiosperms Of Western Australia
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils are in the f ...

Governor Of New South Wales
The governor of New South Wales is the viceregal representative of the Australian monarch, King Charles III, in the state of New South Wales. In an analogous way to the governor-general of Australia at the national level, the governors of the Australian states perform constitutional and ceremonial functions at the state level. The governor is appointed by the king on the advice of the premier of New South Wales, and serves in office for an unfixed period of time—known as serving ''At His Majesty's pleasure''—though five years is the general standard of office term. The current governor is retired jurist Margaret Beazley, who succeeded David Hurley on 2 May 2019. The office has its origin in the 18th-century colonial governors of New South Wales upon its settlement in 1788, and is the oldest continuous institution in Australia. The present incarnation of the position emerged with the Federation of Australia and the ''New South Wales Constitution Act 1902'', which defined t ...

Monotypic Commelinid Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, ''Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.'' ...

Streetsweeper
A street sweeper or street cleaner may refer to a person's occupation or to a machine that cleans streets. Street sweepers have been employed in cities as "sanitation workers" since sanitation and waste removal became a priority. A street-sweeping person would use a broom and shovel to clean off litter, animal waste and filth that accumulated on streets. Later, water hoses were used to wash the streets. Machines were created in the 19th century to do the job more efficiently. Today, modern street sweepers are mounted on truck bodies and can vacuum debris that accumulates in streets. Modern sweepers Street sweepers are capable of collecting small particles of debris. Many street sweepers produced today are PM10 and PM2.5 certified, meaning that they are capable of collecting and holding particulate matter sized less than 10μm and even down to 2.5μm. Despite advancements in street sweeping technology, the mechanical broom type street sweeper accounts for approximat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Lane Poole
Charles Edward Lane Poole (16 August 1885 – 22 November 1970) was an English Australian forester who introduced systematic, science-based forestry practices to various parts of the Commonwealth, most notably Australia. Biography Early life and education in Europe (1885–1906) Poole was born on 16 August 1885 in Easebourne, Sussex, England, the youngest son of Stanley Lane-Poole, an Egyptologist, and his wife Charlotte. His brother Richard was a senior officer in the Royal Navy. In 1900 his father took up a professorship at Trinity College Dublin, moving the family with him, and Lane Poole began attending school at St Columba's College the next year. He then undertook an engineering course, but dropped out after losing his left hand in a shooting accident. He switched to forestry science, graduating from the French National School of Forestry in 1906. Africa (1906–1916) After Lane Poole's graduation from the French National School of Forestry, the British government sent ...
