Olearia Pinifolia
Olearia pinifolia, commonly known as the pine-daisy, is a species of flowering plant in the family Asteraceae and is endemic to Tasmania. It is a shrub with rigid, linear, sharply-pointed leaves and white and yellow, daisy-like inflorescences. Description ''Olearia pinifolia'' is a rigid, bushy shrub that typically grows to a height of and has stout, woolly-hairy branches. The leaves are arranged alternately along the branches, crowded, narrowly linear and long. The leaves are rigid and sharply-pointed with the edges rolled under, giving the plant a pine-like appearance. They are glabrous on the upper surface and silky-hairy on the obsured lower surface. The heads or daisy-like "flowers" are mostly arranged singly on the end of a long peduncle and have a top-shaped involucre. Each "flower" has 8 to 10 white ray florets surrounding a larger number of yellow disc florets. The achenes are long, narrow and smooth, the pappus with bristles in several rows.

Mount Field National Park
Mount Field National Park is a national park in Tasmania, Australia, 64 km northwest of Hobart, Australia, Hobart. The landscape ranges from eucalyptus temperate rainforest to alpine moorland, rising to 1,434 metres (4,705 ft) at the summit of Mount Field West (Tasmania), Mount Field West. History Mount Field National Park was founded in 1916, making it, along with Freycinet National Park, Tasmania's oldest national park. The area around Russell Falls has been protected for its natural beauty since 1885, when it was set aside as Tasmania's first nature reserve. The last known wild thylacine was captured in the region in 1933. The reserve was called "National Park" before 1946, but was officially renamed to its present name in 1947. Etymology Mount Field National Park was named for Judge Barron Field (author), Barron Field, who visited Tasmania as an itinerant judge in 1819 and 1821.

Joseph Dalton Hooker
Sir Joseph Dalton Hooker (30 June 1817 – 10 December 1911) was a British botanist and explorer in the 19th century. He was a founder of geographical botany and Charles Darwin's closest friend. For 20 years he served as director of the Royal Botanical Gardens, Kew, succeeding his father, William Jackson Hooker, and was awarded the highest honours of British science. Biography Early years Hooker was born in Halesworth, Suffolk, England. He was the second son of Maria Sarah Turner, eldest daughter of the banker Dawson Turner and sister-in-law of Francis Palgrave, and the famous botanist Sir William Jackson Hooker, Regius Professor of Botany, Glasgow, Regius Professor of Botany. From the age of seven, Hooker attended his father's lectures at the University of Glasgow, taking an early interest in plant geography, plant distribution and the voyages of explorers like Captain James Cook. He was educated at the High School of Glasgow, Glasgow High School and went on to study med ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olearia
''Olearia'', most commonly known as daisy-bush, is a genus of flowering plants belonging to the family Asteraceae, the largest of the flowering plant families in the world. Olearia are found in Australia, New Guinea and New Zealand. The genus includes herbaceous plants, shrubs and small trees. The latter are unusual among the Asteraceae and are called tree daisies in New Zealand. All bear the familiar daisy-like composite flowerheads in white, pink, mauve or purple. Description Plants in the genus ''Olearia'' are shrubs of varying sizes, characterised by a composite flower head arrangement with single-row ray florets enclosed by small overlapping bracts arranged in rows. The flower petals are more or less equal in length. The centre of the bi-sexual floret is disc shaped and may be white, yellowish or purplish, generally with 5 lobes. Flower heads may be single or clusters in leaf axils or at the apex of branchlets. Leaves may be smooth, glandular or with a sticky secretion. ...

Flora Of Tasmania
The biodiversity of Tasmania is of Biology, biological and Paleoecology, paleoecological interest. A state of Australia, it is a large Australasia, South Pacific archipelago of one large main island and a range of smaller islands. The terrain includes a variety of reefs, atolls, small islands, and a variety of Topography, topographical and Edaphology, edaphic regions on the largest island, all of which promote the development of concentrated biodiversity. During long periods geographically and genetically isolated, it is known for its unique flora and fauna. The region's Oceanic climate, climate is oceanic. Evolution The marine fauna of the period, separate from that of the southwest Pacific, was distinguished as the "Maori province". Gondwana began its fragmentation in the middle and upper Jurassic, and the arrival of benthic invertebrate fauna is visible in fossil deposits. The Cretaceous marked the appearance of marine invertebrate fauna of southern origin. It was then that an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asterales Of Australia
Asterales ( ) is an order of dicotyledonous flowering plants that includes the large family Asteraceae (or Compositae) known for composite flowers made of florets, and ten families related to the Asteraceae. While asterids in general are characterized by fused petals, composite flowers consisting of many florets create the false appearance of separate petals (as found in the rosids). The order is cosmopolitan (plants found throughout most of the world including desert and frigid zones), and includes mostly herbaceous species, although a small number of trees (such as the ''Lobelia deckenii'', the giant lobelia, and ''Dendrosenecio'', giant groundsels) and shrubs are also present. Asterales are organisms that seem to have evolved from one common ancestor. Asterales share characteristics on Morphology (biology), morphological and biochemical levels. Synapomorphies (a character that is shared by two or more groups through evolutionary development) include the presence in the pl ...

Mealybug
Mealybugs are insects in the family Pseudococcidae, unarmored scale insects found in moist, warm habitats. Of the more than 2,000 described species, many are considered pests as they feed on plant juices of greenhouse plants, house plants and subtropical trees and also act as a vector for several plant diseases. Some ants live in symbiotic relationships with them, protecting them from predators and feeding off the honeydew which they excrete. Description Mealybugs are sexually dimorphic: females appear as nymphs, exhibiting reduced morphology, and lack wings, although unlike many female scale insects, they often retain legs and can move. Males are smaller, gnat-like and have wings. Since mealybugs, as well as all other Hemiptera, are hemimetabolous insects, they do not undergo complete metamorphosis in the true sense of the word. However, male mealybugs exhibit a radical change during their life cycle, changing from wingless, ovoid nymphs to wasp-like flying adults. Meal ...

Phytophthora Cinnamomi
''Phytophthora cinnamomi'', also known as cinnamon fungus, is a soil-borne water mould that produces an infection which causes a condition in plants variously called "dieback", "root rot", or (in certain '' Castanea'' species), "ink disease". Once infected soil or water is introduced, the organism can spread rapidly throughout an environment. An infestation can lead to the illness, death, and possible eradication of vulnerable plants, as well as habitat reduction for animals. An outbreak can be challenging to recognize and can inflict irreversible harm to ecosystems. The plant pathogen is one of the world's most invasive species and is present in over 70 countries around the world. Distribution and hosts ''Phytophythora cinnamomi'' is distributed worldwide and can infect a diverse range of hosts, including club mosses, ferns, cycads, conifers, cord rushes, grasses, lilies and a large number of species from many dicotyledonous families, and is included in the Invasive Spe ...

Mount Sorell
Mount Sorell is a mountain located in the West Coast region of Tasmania, Australia. With an elevation of above sea level, the mountain is the most south westerly of all the peaks within the West Coast Range. History The mountain was named in honour of William Sorell (1775 – 4 June 1848), a soldier who served as the third Lieutenant-Governor of Van Diemen's Land. Alluvial gold was found in adjacent creeks in the 1880s. Geology Its eastern face dominates the Clark River valley, which separates it from Mount Darwin. Because of its position, its appearance and dominance over the Macquarie Harbour just north east of Sarah Island, it was an early named mountain, and no doubt one which gave a sense of barrier to convicts with dreams of escape. Some folklore passed from convict times claim leg irons or other items were found by troops looking for escaped convicts on its slopes. It has no points of access like the nearby mountains, and in general remains relatively untouched ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Dundas (Tasmania)
Mount Dundas is a mountain located in the West Coast region of Tasmania, Australia. The mountain is situated at the north west edge of the West Coast Range. As colourful a history as that of Mount Lyell, Mount Dundas has had a range of mines and railways such as the North East Dundas Tramway within its vicinity. The name is also incorporated into the name of the major newspaper of the west coast, the '' Zeehan and Dundas Herald''. The main copper and gold ore bearing deposits in the West Coast Range are known as occurring in the 'Mount Read Volcanics' relating to the complex geology of the area, and also silver at Mount Dundas.

Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (often shortened to just "binomial"), a binomen, name, or a scientific name; more informally, it is also called a Latin name. In the International Code of Zoological Nomenclature (ICZN), the system is also called nomenclature, with an "n" before the "al" in "binominal", which is a typographic error, meaning "two-name naming system". The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Hom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
