Eucalyptus Regnans
''Eucalyptus regnans'', known variously as mountain ash (in Victoria), giant ash or swamp gum (in Tasmania), or stringy gum, is a species of very tall forest tree that is native to the Australia states of Tasmania and Victoria. It is a straight-trunked tree with smooth grey bark, but with a stocking of rough brown bark at the base, glossy green, lance-shaped to curved adult leaves, flower buds in groups of between nine and fifteen, white flowers, and cup-shaped or conical fruit. It is the tallest of all flowering plants; the tallest measured living specimen, named Centurion, stands 100 metres (328 feet) tall in Tasmania. It often grows in pure stands in tall wet forest, sometimes with rainforest understorey, and in temperate, high rainfall areas with deep loam soils. A large number of the trees have been logged, including some of the tallest known. This species of eucalypt does not possess a lignotuber and is often killed by bushfire, regenerating from seed.

Black Spur
The Black Spur is a road between the towns of Healesville and Narbethong in Victoria, Australia. It is also known as Black Spur Drive and is part of the Maroondah Highway. Location The Black Spur is approximately 60 kilometres northeast of Melbourne on the Maroondah Highway between Healesville and Marysville. Etymology Originally known as "The Blacks' Spur", the road gained its name from the route that displaced Aboriginal people from northern Victoria used to take on their way to a settlement at Corranderrk, near Healesville. History During the mid-1890s depression, German-born Melbourne photographer John William Lindt closed his studio. As early as 1883 he had been exhibiting pictures of the Blacks' Spur, where he built and moved to a guesthouse, ''The Hermitage'', in gardens set out by his friend Ferdinand von Mueller. The gardens feature New Guinea tree houses from which Lindt made frequent panoramas of his property and surrounding primeval forest of towering, 30- ...

Peduncle (botany)
In botany, a peduncle is a stalk supporting an inflorescence or a solitary flower, or, after fecundation, an infructescence or a solitary fruit. The peduncle sometimes has bracts (a type of cataphyll) at nodes. The main axis of an inflorescence above the peduncle is the rachis, which hosts flowers (as opposed to directly on the peduncle). When a peduncle arises from the ground level, either from a compressed aerial stem or from a subterranean stem (rhizome, tuber, bulb, corm), with few or no bracts except the part near the rachis or receptacle, it is referred to as a scape. The acorns of the pedunculate oak are borne on a long peduncle, hence the name of the tree. See also *Pedicel (botany) *Scape (botany) In botany, a scape is a peduncle arising from a subterranean or very compressed stem, with the lower internodes very long and hence few or no bracts except the part near the rachis or receptacle. Typically it takes the form of a long, leafl ... Referen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eucalyptus Fastigata
''Eucalyptus fastigata'', commonly known as brown barrel or cut-tail, is a species of medium-sized to tall tree that is endemic to southeastern Australia. It has fibrous or stringy bark on the trunk and larger branches, smooth bark above, lance-shaped to curved adult leaves, flower buds in groups of eleven or more, white flowers and conical or pair-shaped fruit. Description ''Eucalyptus fastigata'' is typically a tall, straight tree that grows to a height of but does not form a lignotuber. It has rough, fibrous or stringy bark on the trunk and larger branches, smooth white to brown bark above which often hangs in strings in the crown. Young plants and coppice regrowth have petiolate, broadly elliptical to egg-shaped leaves long and wide. Adult leaves are more or less the same glossy green on both sides, lance-shaped to curved, long and wide on a petiole long. The flower buds are arranged in leaf axils in groups of eleven, thirteen fifteen or more, the groups often paired, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quercus Robur
''Quercus robur'', the pedunculate oak, is a species of flowering plant in the beech and oak family, Fagaceae. It is a large tree, native plant, native to most of Europe and western Asia, and is widely cultivated in other temperate regions. It grows on soils of near neutral Soil pH, acidity in the lowlands and is notable for its value to natural ecosystems, supporting a very wide diversity of herbivorous insects and other pests, predators and pathogens. Description Pedunculate oak is a deciduous tree up to tall, with a single stout trunk that can be as much as in girth (circumference at breast height) or even 14 m in Pollarding, pollarded specimens. Older trees tend to be pollarded, with boles (the main trunk) about 3 m long. They often live longer and become more stout than unpollarded trees. The crown is spreading and unevenly domed, and trees often have massive lower branches. The bark is greyish-brown and closely grooved, with vertical plates. There are often large burrs ...

Fraxinus
''Fraxinus'' (), commonly called ash, is a genus of plants in the olive and lilac family, Oleaceae, and comprises 45–65 species of usually medium-to-large trees, most of which are deciduous trees, although some Subtropics, subtropical species are evergreen trees. The genus is widespread throughout much of Europe, Asia, and North America. The leaves are opposite leaves, opposite (rarely in Whorl (botany), whorls of three), and mostly pinnate, pinnately compound, though simple in a few species. The seeds, popularly known as "keys" or "helicopter seeds", are a type of fruit known as a samara (fruit), samara. Some ''Fraxinus'' species are Dioecy, dioecious, having male and female flowers on separate plants but sex in ash is expressed as a continuum between male and female individuals, dominated by unisexual trees. With age, ash may change their sexual function from predominantly male and hermaphrodite towards femaleness; if grown as an ornamental and both sexes are present, ashes ...

Dandenong Ranges
The Dandenong Ranges (commonly just the Dandenongs) are a set of low mountain ranges in Victoria, Australia, approximately east of the state capital Melbourne. A minor branch of the Great Dividing Range, the Dandenongs consist mostly of rolling hills, rising to at Mount Dandenong, as well as steeply weathered valleys and gullies covered in thick temperate rainforest, predominantly of tall mountain ash trees and dense ferny undergrowth. The namesake Dandenong Creek and most of its left-bank tributaries (particularly the Eumemmerring Creek) originate from headwaters in these mountain ranges. Two of Melbourne's most important storage reservoirs, the Cardinia and Silvan Reservoir, are also located within the Dandenongs. After European settlement in the Port Phillip Bay region, the range was used as a major local source of timber for Melbourne. The ranges were popular with day-trippers from the 1870s onwards. Much of the Dandenongs were protected as parklands as early as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James Hamlyn Willis
James Hamlyn Willis (28 January 1910 – 10 November 1995) was an Australian botanist. He described 64 new species of plants, and published more than 880 works including the landmark two-volume ''A Handbook to plants in Victoria'' between 1962 and 1973. Life Willis was born in Oakleigh, Victoria in 1910. In 1913 he moved with his family to Stanley, Tasmania, Stanley on the northern coast of Tasmania, Australia, where they remained until returning to Victoria in 1924. He attended Melbourne High School and in 1928, following receipt of a scholarship, began studies at the Victorian School of Forestry in Creswick, Victoria, Creswick, graduating with a Diploma of Forestry in 1930. For the next seven years he was employed by the Forests Commission of Victoria as a forest officer. In 1937 Willis joined the National Herbarium of Victoria and commenced studies at the University of Melbourne, graduating with a Bachelor of Science (Honours) in 1940. Between 1958 and 1959, he held the pos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Systematic Census Of Australian Plants
The ''Systematic census of Australian plants, with chronologic, literary and geographic annotations'', more commonly known as the ''Systematic Census of Australian Plants'', also known by its standard botanic abbreviation ''Syst. Census Austral. Pl.'', is a survey of the vascular flora of Australia prepared by Government botanist for the state of Victoria Ferdinand von Mueller and published in 1882. Von Mueller describes the development of the census in the preface of the volume as an extension of the seven volumes of the ''Flora Australiensis'' written by George Bentham. A new flora was necessary since as more areas of Australia were explored and settled, the flora of the island-continent became better collected and described. The first census increased the number of described species from the 8125 in ''Flora Australiensis'' to 8646. The book records all the known species indigenous to Australia and Norfolk Island; with records of species distribution. Von Mueller noted tha ...

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 cultivar group, 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, Fungus, fungi, or plants, whether fossil or non-fossil, including blue-green algae (Cyanobacteria), Chytridiomycota, chytrids, oomycetes, slime moulds and Photosynthesis, 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 variou ...

Cotyledon
A cotyledon ( ; ; "a cavity, small cup, any cup-shaped hollow", gen. (), ) is a "seed leaf" – a significant part of the embryo within the seed of a plant – and is formally defined as "the embryonic leaf in seed-bearing plants, one or more of which are the first to appear from a germinating seed." Botanists use the number of cotyledons present as one characteristic to classify the flowering plants (angiosperms): species with one cotyledon are called monocotyledonous ("monocots"); plants with two embryonic leaves are termed dicotyledonous ("dicots"). Many orchids with minute seeds have no identifiable cotyledon, and are regarded as acotyledons. The Dodders (''Cuscuta'' spp) also lack cotyledons, as does the African tree '' Mammea africana'' ( Calophyllaceae). In the case of dicot seedlings whose cotyledons are photosynthetic, the cotyledons are functionally similar to leaves. However, true leaves and cotyledons are developmentally distinct. Cotyledons form during embryo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hilum (biology)
In botany, a hilum (pronounced ) is a scar or mark left on a seed coat by the former attachment to the ovary wall or to the funiculus (which in turn attaches to the ovary wall). On a bean seed, the hilum is called the "eye". For some species of fungus, the hilum is the microscopic indentation left on a spore when it separates from the sterigma of the basidium. A hilum can also be a nucleus of a starch grain; the point around which layers of starch are deposited. The adjectival form ''hilar'' denotes the presence of such a mark, and can be used as a distinguishing characteristic of a seed or spore In biology, a spore is a unit of sexual reproduction, sexual (in fungi) or asexual reproduction that may be adapted for biological dispersal, dispersal and for survival, often for extended periods of time, in unfavourable conditions.
