Leptoceras
''Leptoceras menziesii'', commonly known as rabbit orchid, is a plant in the orchid family, Orchidaceae and the only member of the genus ''Leptoceras''. It is a slender plant, usually found in large colonies and which only flowers after fire. The flowers are small, white, pink and red on a stem up to tall and is endemic to southern Australia. It was one of the first orchids from Western Australia to be described and was given the name ''Caladenia menziesii'', a name still used by some authorities. Description The rabbit orchid is a tuberous perennial herb growing to a height of , sometimes with one to three flowers. The leaf is glabrous, variable in size and shape but mostly lance-shaped to broadly egg-shaped to oblong, long and wide. There are one to three small flowers, sometimes all white but more usually white, pink and red. The top sepal at the back of the flower is about long, dark reddish, spoon-shaped and forms a hood over the column. The back of the dorsal sepal h ...

American River, South Australia
American River is a town in the Australian state of South Australia located on the western shore of Eastern Cove on Kangaroo Island. History The area now known as American River was first visited by Europeans in 1802 when Matthew Flinders landed to survey this part of Kangaroo Island. In 1803, a group of American sealers camped for four months in the area. They arrived on the brig and built their own 35 ton schooner ''Independence'' from local timber. The town takes its name from this time. A memorial plaque and accompanying anchor (recovered in 1969) from an early American whaling vessel is dedicated to ''Union'' s crew. Frank Potts was the first official settler in 1842, before moving to the mainland and establishing the ''Bleasdale'' vineyard and winery at Langhorne Creek. John Buick, a professional boat builder, built the first house in the town in 1844. It was fashioned out of local stone, pug and sput timber and remained standing until 1985. A fish canning facto ...

Gland (botany)
In plants, a gland is defined functionally as a plant structure which secretes one or more products. This may be located on or near the plant surface and secrete externally, or be internal to the plant and secrete into a canal or reservoir. Examples include glandular hairs, nectaries, hydathodes, and the resin canals in Pinus. Notable examples Salt glands of the mangrove The salt glands of mangroves such as '' Acanthus'', ''Aegiceras'', ''Aegialitis'' and ''Avicennia'' are a distinctive multicellular trichome, a glandular hair found on the upper leaf surface and much more densely in the abaxial indumentum. On the upper leaf surface they are sunken in shallow pits, and on the lower surface they occur scattered among long nonglandular hairs composed of three or four cells. Development of the glands resembles that of the nonglandular hairs until the three-celled stage, when the short middle stalk cell appears. The salt gland continues to develop to produce two to four vacuola ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Victoria, Australia
Victoria is a state in southeastern Australia. It is the second-smallest state with a land area of , the second most populated state (after New South Wales) with a population of over 6.5 million, and the most densely populated state in Australia (28 per km2). Victoria is bordered by New South Wales to the north and South Australia to the west, and is bounded by the Bass Strait to the south (with the exception of a small land border with Tasmania located along Boundary Islet), the Great Australian Bight portion of the Southern Ocean to the southwest, and the Tasman Sea (a marginal sea of the South Pacific Ocean) to the southeast. The state encompasses a range of climates and geographical features from its temperate coastal and central regions to the Victorian Alps in the northeast and the semi-arid north-west. The majority of the Victorian population is concentrated in the central-south area surrounding Port Phillip Bay, and in particular within the metropolitan area ...

Vegetative Reproduction
Vegetative reproduction (also known as vegetative propagation, vegetative multiplication or cloning) is any form of asexual reproduction occurring in plants in which a new plant grows from a fragment or cutting of the parent plant or specialized reproductive structures, which are sometimes called vegetative propagules. Many plants naturally reproduce this way, but it can also be induced artificially. Horticulturists have developed asexual propagation techniques that use vegetative propagules to replicate plants. Success rates and difficulty of propagation vary greatly. Monocotyledons typically lack a vascular cambium, making them more challenging to propagate. Background Plant propagation is the process of plant reproduction of a species or cultivar, and it can be sexual or asexual. It can happen through the use of vegetative parts of the plants, such as leaves, stems, and roots to produce new plants or through growth from specialized vegetative plant parts. While m ...

Botanical Name
A botanical name is a formal scientific name conforming to the '' International Code of Nomenclature for algae, fungi, and plants'' (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the ''International Code of Nomenclature for Cultivated Plants'' (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae ( Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." The purpose of a formal name is to have a single name that is accepted and used worldwide for a particular plant or plant group. For example, the botanical name ''Bellis perennis'' denotes a plant species which is native to most of the countries of Europe and the Middle East, where it has accumulated various names in many languages. Later, the plant was intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prodromus Florae Novae Hollandiae Et Insulae Van Diemen
''Prodromus Florae Novae Hollandiae et Insulae Van Diemen'' (Prodromus of the Flora of New Holland and Van Diemen's Land) is a flora of Australia written by botanist Robert Brown and published in 1810. Often referred to as ''Prodromus Flora Novae Hollandiae'', or by its standard botanical abbreviation ''Prodr. Fl. Nov. Holland.'', it was the first attempt at a survey of the Australian flora. It described over 2040 species, over half of which were published for the first time. Brown's ''Prodromus'' was originally published as Volume One, and following the ''Praemonenda'' (Preface), page numbering commences on page 145. Sales of the ''Prodromus'' were so poor, however, that Brown withdrew it from sale. Due to the commercial failure of the first volume, pages 1 to 144 were never issued, and Brown never produced the additional volumes that he had planned. In 1813, a book of illustrations for the ''Prodromus'' was published separately by Ferdinand Bauer under the title ''Ferdinandi Ba ...

Vancouver Expedition
The Vancouver Expedition (1791–1795) was a four-and-a-half-year voyage of exploration and diplomacy, commanded by Captain George Vancouver of the Royal Navy. The British expedition circumnavigated the globe and made contact with five continents. The expedition at various times included between two and four vessels, and up to 153 men, all but 6 of whom returned home safely. Origin Several previous voyages of exploration including those of Ferdinand Magellan and James Cook, and the Spanish Manila-Acapulco galleons trade route active since 1565, had established the strategic and commercial value of exploring and claiming the Pacific Ocean access, both for its wealth in whales and furs and as a trade route to the "Orient". Britain was especially interested in improving its knowledge of the Southern Pacific whale fisheries, and in particular the location of the strategically positioned Australia, New Zealand, the legendary ''Isla Grande'', and the Northwest Passage. A new ship was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
King George Sound
King George Sound ( nys , Menang Koort) is a sound on the south coast of Western Australia. Named King George the Third's Sound in 1791, it was referred to as King George's Sound from 1805. The name "King George Sound" gradually came into use from about 1934, prompted by new Admiralty charts supporting the intention to eliminate the possessive 's' from geographical names. The sound covers an area of and varies in depth from . Situated at its western shore is the city of Albany. The sound is bordered by the mainland to the north, by Vancouver Peninsula on the west, and by Bald Head and Flinders Peninsula to the south. Although the sound is open water to the east, the waters are partially protected by Breaksea Island and Michaelmas Island. There are two harbours located within the sound, Princess Royal Harbour to the west and Oyster Harbour to the north. Each receives excellent protection from winds and heavy seas. Princess Royal Harbour was Western Australia's only deep-wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessarily "typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archibald Menzies
Archibald Menzies ( ; 15 March 1754 – 15 February 1842) was a Scottish surgeon, botanist and naturalist. He spent many years at sea, serving with the Royal Navy, private merchants, and the Vancouver Expedition. He was the first recorded European to reach the summit of the Hawaiian volcano Mauna Loa and introduced the Monkey Puzzle tree to England. Life and career Menzies was born at Easter Stix (or Styx) in the parish of Weem, in Perthshire, Scotland. While working with his elder brother William at the Royal Botanic Gardens, he drew the attention of Dr John Hope, professor of botany at Edinburgh University, who encouraged him to study medicine there. Having qualified as a surgeon, Menzies served as assistant to a doctor in Caernarvon, Wales, then joined the Royal Navy as assistant surgeon on . Present at Battle of the Saintes (12 April 1782), in peacetime Menzies served on Halifax Station in Nova Scotia. In 1786 Menzies was appointed surgeon on board the ''Prince of W ...

Bushfires In Australia
Bushfires in Australia are a widespread and regular occurrence that have contributed significantly to shaping the nature of the continent over millions of years. Eastern Australia is one of the most fire-prone regions of the world, and its predominant eucalyptus forests have evolved to thrive on the phenomenon of bushfire. However, the fires can cause significant property damage and loss of both human and animal life. Bushfires have killed approximately 800 people in Australia since 1851, and billions of animals. The most destructive fires are usually preceded by extreme high temperatures, low relative humidity and strong winds, which combine to create ideal conditions for the rapid spread of fire. Severe fire storms are often named according to the day on which they peaked, including the five most deadly blazes: Black Saturday 2009 in Victoria (173 people killed, 2,000 homes lost); Ash Wednesday 1983 in Victoria and South Australia (75 dead, nearly 1,900 homes); Black Frida ...

Callus
A callus is an area of thickened and sometimes hardened skin that forms as a response to repeated friction, pressure, or other irritation. Since repeated contact is required, calluses are most often found on the feet and hands, but they may occur anywhere on the skin. Some degree of callus, such as on the bottom of the foot, is normal. Calluses are generally not harmful and help prevent blisters, as well as offering protection. However, excessive formation may sometimes lead to other problems, such as a skin ulceration or infection, or cause the affected person to try to offload the affected painful area, which can place excessive stress on the asymptomatic side. Rubbing that is too frequent or forceful will cause blisters, as opposed to calluses, to form. Cause Normally, a callus will form on any part of the skin exposed to excess friction over a long period of time. Activities that are known for causing calluses include (but are not limited to) construction work, many ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
