Epacris Corymbiflora
''Epacris corymbiflora'' is a species of flowering plant in the heath family, Ericaceae, and is endemic to Tasmania. It is a low, spreading shrub with elliptic leaves and white, tube-shaped flowers. Description ''Epacris corymbiflora'' is a spreading shrub that grows up to high and wide. The leaves are crowded, elliptic or diamond-shaped, long with a small point on the tip and the edges curved upwards. Both sides of the leaves are green and there are a few more or less parallel veins. Flowering occurs in summer and the flowers are arranged in dense, more or less spherical groups near the ends of branches, each flower tube-shaped, white and about in diameter. Taxonomy and naming ''Epacris corymbiflora'' was first formally described in 1857 by Joseph Dalton Hooker in '' The botany of the Antarctic voyage of H.M. Discovery ships Erebus and Terror. III. Flora Tasmaniae'' from specimens collected near the Franklin River in Macquarie Harbour by Ronald Campbell Gunn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Field National Park
Mount Field National Park is a national park in Tasmania, Australia, 64 km northwest of 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. 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, who visited Tasmania as an itinerant judge in 1819 and 1821. Geology During the Pleistocene period, a snowfield covered the top of the Mount Field plateau and fed glaciers in the surrounding valleys. A large, 12&nb ...

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 twenty 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 the famous botanist Sir William Jackson Hooker, Regius Professor of Botany, and Maria Sarah Turner, eldest daughter of the banker Dawson Turner and sister-in-law of Francis Palgrave. From age seven, Hooker attended his father's lectures at Glasgow University, taking an early interest in plant distribution and the voyages of explorers like Captain James Cook. He was educated at the Glasgow High School and went on to study medicine at Glasgow University, graduating M.D. in 1839. This degree qualified him for ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Ericaceae
The Ericaceae are a family of flowering plants, commonly known as the heath or heather family, found most commonly in acidic and infertile growing conditions. The family is large, with c.4250 known species spread across 124 genera, making it the 14th most species-rich family of flowering plants. The many well known and economically important members of the Ericaceae include the cranberry, blueberry, huckleberry, rhododendron (including azaleas), and various common heaths and heathers (''Erica'', ''Cassiope'', ''Daboecia'', and ''Calluna'' for example). Description The Ericaceae contain a morphologically diverse range of taxa, including herbs, dwarf shrubs, shrubs, and trees. Their leaves are usually evergreen, alternate or whorled, simple and without stipules. Their flowers are hermaphrodite and show considerable variability. The petals are often fused (sympetalous) with shapes ranging from narrowly tubular to funnelform or widely urn-shaped. The corollas are usually ra ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Tasmaniae
The ''Flora Tasmaniae'' is a description of the plants discovered in Tasmania during the Ross expedition written by Joseph Dalton Hooker and published by Reeve Brothers in London between 1855 and 1860. Hooker sailed on HMS ''Erebus'' as assistant surgeon. Written in two volumes, it was the last in a series of four Floras in the ''Flora Antarctica'', the others being the '' Botany of Lord Auckland's Group and Campbell's Island'' (1843–1845), the '' Botany of Fuegia, the Falklands, Kerguelen's Land, Etc.'' (1845-47), and the '' Flora Novae-Zelandiae'' (1851–1853). They were "splendidly" illustrated by Walter Hood Fitch. The larger part of the plant specimens collected during the Ross expedition are now part of the Kew Herbarium. Although Hooker professed not to have changed his views on Darwin's theory of evolution by natural selection, the book contains an introductory essay on biogeography written from a Darwinian point of view, making the book the first case study for the t ...

Franklin River
The Franklin River is a major perennial river located in the Central Highlands and western regions of Tasmania, Australia. The river is located in the Franklin-Gordon Wild Rivers National Park at the mid northern area of the Tasmanian Wilderness World Heritage Area. Its source is situated at the western edge of the Central Highlands and it flows west towards the West Coast. The river is named in honour of Sir John Franklin, a Governor of Tasmania, who later died searching for the Northwest Passage. Location and features The river rises below Mount Hugel west of Derwent Bridge on the western slopes of the Central Highlands and flows generally west and south through remote and rugged mountainous country until meeting its confluence with the Gordon River. From source to mouth the river is joined by sixteen tributaries including the Surprise, Collingwood, Lucan, Loddon, Andrew and the Jane rivers. In its upper reaches, the Franklin is impounded by two reservoirs, Lake Undine an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macquarie Harbour
Macquarie Harbour is a shallow fjord in the West Coast region of Tasmania, Australia. It is approximately , and has an average depth of , with deeper places up to . It is navigable by shallow-draft vessels. The main channel is kept clear by the presence of a rock wall on the outside of the channel's curve. This man-made wall prevents erosion and keeps the channel deep and narrow, rather than allowing the channel to become wide and shallow. A reported Aboriginal name for the harbour is ''Parralaongatek''. The harbour was named in honour of Scottish Major General Lachlan Macquarie, the fifth Colonial Governor of New South Wales. History James Kelly wrote in his narrative ''First Discovery of Port Davey and Macquarie Harbour'' how he sailed from Hobart in a small open five-oared whaleboat to discover Macquarie Harbour on 28 December 1815. However, different accounts of the journey have indicated different methods and dates of the discovery. In the commentary to the ''Historical ...

Gymnoschoenus Sphaerocephalus
''Gymnoschoenus sphaerocephalus'', commonly known as buttongrass, is a species of tussock-forming sedge from southeastern Australia. It forms part of a unique habitat in Tasmania. It was originally described as ''Chaetospora sphaerocephala'' by Scottish botanist Robert Brown in his 1810 work ''Prodromus Florae Novae Hollandiae et Insulae Van Diemen'', before being given its current binomial name in 1858 by Joseph Dalton Hooker. ''G. sphaerocephalus'' is a perennial sedge species which forms a clump or tussock. The leaf blades reach in length, and in width. The round flowerheads arise out of the tussock, on culms which are up to high. They are around in diameter and made up of flattened spikelets long. Its root system is a mass of fleshy carbohydrate-rich rhizomes, which are edible. In New South Wales it is found from Gibraltar Range (and Myall Lakes on the coast) south to Robertson. In Victoria the plant is known from at least two locations, one to the east of Melbourne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epacris
''Epacris'' is a genus of about forty species of flowering plants in the family Ericaceae. It was formerly treated in a closely related but separate family Epacridaceae, but the various genera within Epacridaceae including ''Epacris'' have been revised in their relationships to each other and brought under the common umbrella of the Ericaceae. The genus ''Epacris'' is native to eastern and southeastern Australia (southeast Queensland south to Tasmania and west to southeast South Australia), New Caledonia and New Zealand. The species are known as heaths or Australian heaths. Description Plants in the genus ''Epacris'' are shrubs with simple leaves that are a similar colour on both surfaces and with flowers arranged singly in leaf axils near the ends of the branches, sometimes extending along the branches. Each flower is surrounded by many bracts and five, usually glabrous sepals. The petals are joined to produce a cylindrical or bell-like tube with five lobes on the end. The ...
