Eucalyptus Crebra
''Eucalyptus crebra'', commonly known as the narrow-leaved ironbark, narrow-leaved red ironbark or simply ironbark, and as muggago in the indigenous Dharawal language, is a species of small to medium-sized tree endemic to eastern Australia. It has hard, rough "ironbark" from its trunk to small branches, linear to lance-shaped adult leaves, flower buds in groups of seven, nine or eleven, white flowers and cup-shaped, barrel-shaped or hemispherical fruit. A variable species, it grows in woodland and forest from the Cape York Peninsula to near Sydney. It is an important source of nectar in the honey industry and its hard, strong timber is used in construction. Description ''Eucalyptus crebra'' is a tree that typically grows to a height of and forms a lignotuber. It has persistent thick, rough, deeply furrowed, greyish black "ironbark" from the base of its trunk to the small branches. Young plants and coppice regrowth have linear to lance-shaped or curved leaves long and wide. Adul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ferdinand Von Mueller
Baron Sir Ferdinand Jacob Heinrich von Mueller, (german: Müller; 30 June 1825 – 10 October 1896) was a German-Australian physician, geographer, and most notably, a botanist. He was appointed government botanist for the then colony of Victoria (Australia) by Governor Charles La Trobe in 1853, and later director of the Royal Botanic Gardens, Melbourne. He also founded the National Herbarium of Victoria. He named many Australian plants. Early life Mueller was born at Rostock, in the Grand Duchy of Mecklenburg-Schwerin. After the early death of his parents, Frederick and Louisa, his grandparents gave him a good education in Tönning, Schleswig. Apprenticed to a chemist at the age of 15, he passed his pharmaceutical examinations and studied botany under Professor Ernst Ferdinand Nolte (1791–1875) at Kiel University. In 1847, he received his degree of Doctor of Philosophy from Kiel for a thesis on the plants of the southern regions of Schleswig. Mueller's sister Bertha had be ...

Capsule (botany)
In botany a capsule is a type of simple, dry, though rarely fleshy dehiscent fruit produced by many species of angiosperms (flowering plants). Origins and structure The capsule (Latin: ''capsula'', small box) is derived from a compound (multicarpeled) ovary. A capsule is a structure composed of two or more carpels. In (flowering plants), the term locule (or cell) is used to refer to a chamber within the fruit. Depending on the number of locules in the ovary, fruit can be classified as uni-locular (unilocular), bi-locular, tri-locular or multi-locular. The number of locules present in a gynoecium may be equal to or less than the number of carpels. The locules contain the ovules or seeds and are separated by septa. Dehiscence In most cases the capsule is dehiscent, i.e. at maturity, it splits apart (dehisces) to release the seeds within. A few capsules are indehiscent, for example those of ''Adansonia digitata'', ''Alphitonia'', and '' Merciera''. Capsules are often classifie ...

Railroad Tie
A railroad tie, crosstie (American English), railway tie (Canadian English) or railway sleeper (Australian and British English) is a rectangular support for the rails in railroad tracks. Generally laid perpendicular to the rails, ties transfer loads to the track ballast and subgrade, hold the rails upright and keep them spaced to the correct gauge. Railroad ties are traditionally made of wood, but prestressed concrete is now also widely used, especially in Europe and Asia. Steel ties are common on secondary lines in the UK; plastic composite ties are also employed, although far less than wood or concrete. As of January 2008, the approximate market share in North America for traditional and wood ties was 91.5%, the remainder being concrete, steel, azobé (red ironwood) and plastic composite. Tie spacing may depend on the type of tie, traffic loads and other requirements, for example 2640 concrete ties per mile on North American mainline railroads to 2112 timber ties per mile ...

Cairns
Cairns (, ) is a city in Queensland, Australia, on the tropical north east coast of Far North Queensland. The population in June 2019 was 153,952, having grown on average 1.02% annually over the preceding five years. The city is the 5th-most-populous in Queensland, and 15th in Australia. The city was founded in 1876 and named after Sir William Wellington Cairns, following the discovery of gold in the Hodgkinson river. Throughout the late 19th century, Cairns prospered from the settlement of Chinese immigrants who helped develop the region's agriculture. Cairns also served as a port for blackbirding ships, bringing slaves and indentured labourers to the sugar plantations of Innisfail. During World War II, the city became a staging ground for the Allied Forces in the Battle of the Coral Sea. By the late 20th century the city had become a centre of international tourism, and in the early 21st century has developed into a major metropolitan city. Cairns is a popular tourist ...

Picton, New South Wales
Picton is a small town in the Macarthur Region of New South Wales, Australia, in the Wollondilly Shire, in south-western Sydney. The town is located approximately 90 kilometres south-west of Sydney, close to Camden and Campbelltown. It is also the administrative centre of Wollondilly Shire. History Picton was first explored by Europeans in 1798 and remained beyond the limits of legal settlement until 1821. Following the discovery of good land in the interior and the settlement of Bong Bong and the Goulburn areas, Governor Macquarie authorised the building of the new Great South Road between Sydney and the Southern Highlands in 1819. This opened up the Picton area to settlers, including Henry Colden Antill, who established a property in 1822. Picton developed when a new line of the Great South Road was cut over the Razorback Range from Camden, and especially after the railway arrived in 1863. Picton is the only town in the Southern Hemisphere that one can pass through t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Taxonomic Synonym
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia leva ...
