Acacia Truncata
''Acacia truncata'', commonly known as the angle leaved wattle or west coast wattle, is a coastal shrub in the family Fabaceae, with a native distribution along the southwest coast of Western Australia. A specimen of this wattle was part of an early European botanical collection, perhaps the first from Australia. Description The shrub is a dense and dome shaped plant high. It has ribbed and glabrous branchlets. Flowerheads are globe-shaped and composed of 7-16 pale yellow flowers, on stalks between long. Following flowering it will form blackish curved to linear seed pods that are about in length and wide with thick yellowish margins. The shiny brown seeds are longitudinally arranged in the pod. They have an oblong to elliptic shape and are long. Like many other ''Acacia'' species, ''A. truncata'' has phyllodes rather than true leaves. The triangular phyllodes range from long and wide. Taxonomy The species was initially described as ''Adiantum truncatum'' by Nicolaas Lau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burm
A berm is a level space, shelf, or raised barrier (usually made of compacted soil) separating areas in a vertical way, especially partway up a long slope. It can serve as a terrace road, track, path, a fortification line, a border/separation barrier for navigation, good drainage, industry, or other purposes. Etymology The word is one of Middle Dutch and came into usage in English via French. Military use History In medieval military engineering, a berm (or berme) was a level space between a parapet or defensive wall and an adjacent steep-walled ditch A ditch is a small to moderate divot created to channel water. A ditch can be used for drainage, to drain water from low-lying areas, alongside roadways or fields, or to channel water from a more distant source for plant irrigation. Ditches ar ... or moat. It was intended to reduce soil pressure on the walls of the excavated part to prevent its collapse. It also meant that debris dislodged from fortifications would not ...

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

Acacias Of Western Australia
''Acacia'', commonly known as the wattles or acacias, is a large genus of shrubs and trees in the subfamily Mimosoideae of the pea family Fabaceae. Initially, it comprised a group of plant species native to Africa and Australasia. The genus name is New Latin, borrowed from the Greek (), a term used by Dioscorides for a preparation extracted from the leaves and fruit pods of ''Vachellia nilotica'', the original type of the genus. In his ''Pinax'' (1623), Gaspard Bauhin mentioned the Greek from Dioscorides as the origin of the Latin name. In the early 2000s it had become evident that the genus as it stood was not monophyletic and that several divergent lineages needed to be placed in separate genera. It turned out that one lineage comprising over 900 species mainly native to Australia, New Guinea, and Indonesia was not closely related to the much smaller group of African lineage that contained ''A. nilotica''—the type species. This meant that the Australasian lineage (by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Acacia Species
Several Cladistics, cladistic analyses have shown that the genus ''Acacia sensu lato, Acacia'' is not monophyletic. While the subg. ''Acacia'' and subg. ''Phyllodinae'' are monophyletic, subg. ''Aculeiferum'' is not. This subgenus consists of three clades. Therefore, the following list of ''Acacia'' species cannot be maintained as a single entity, and must either be split up, or broadened to include species previously not in the genus. This genus has been provisionally divided into 5 genus, genera, ''Acacia'', ''Vachellia'', ''Senegalia'', ''Acaciella'' and ''Mariosousa''. The proposed type species of ''Acacia'' is ''Acacia penninervis''. Which of these segregate genera is to retain the name ''Acacia'' has been controversial. The genus was previously typified with the African species ''Acacia scorpioides'' (L.) W.F.Wright, a synonym of ''Acacia nilotica'' (L.) Delile. Under the original typification, the name ''Acacia'' would stay with the group of species currently recognized ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frost
Frost is a thin layer of ice on a solid surface, which forms from water vapor in an above-freezing atmosphere coming in contact with a solid surface whose temperature is below freezing, and resulting in a phase change from water vapor (a gas) to ice (a solid) as the water vapor reaches the freezing point. In temperate climates, it most commonly appears on surfaces near the ground as fragile white crystals; in cold climates, it occurs in a greater variety of forms. The propagation of crystal formation occurs by the process of nucleation. The ice crystals of frost form as the result of fractal process development. The depth of frost crystals varies depending on the amount of time they have been accumulating, and the concentration of the water vapor (humidity). Frost crystals may be invisible (black), clear (translucent), or white; if a mass of frost crystals scatters light in all directions, the coating of frost appears white. Types of frost include crystalline frost (hoar fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harvey, Western Australia
Harvey is a town located in the South West of Western Australia along the South Western Highway, south of Perth, between Pinjarra and Bunbury. It has a population of 2,750. Harvey Town is known for its dairy industry and oranges. History Harvey's name is derived from the nearby Harvey River, named by Governor James Stirling in 1829, soon after the river's discovery by explorers Alexander Collie and Lieutenant William Preston RN. Although not positively known, the river is most likely named after Rear Admiral John Harvey. In 1817–18, Harvey was Commander in Chief of the West Indies StationStirling served under him while in charge of , and Harvey recommended him for promotion.

Carnamah, Western Australia
Carnamah is a town in the Mid West region of Western Australia, about north of Perth along the Midlands Road. According to 2021 census, the population of the town is 407. The town was gazetted in 1913, and is named after "Carnamah", the name of a pastoral property established by Duncan Macpherson in this location in the late 1860s. A telegraph station was established here in 1873, and is referred to in 1876 by the explorer Ernest Giles. Giles spells it "Cornamah" in his book, but "Carnamah" on his map. Macpherson's property "Carnamah" derives its name from Carnamah Spring. The name is probably Aboriginal of unknown meaning, or possibly is a Gaelic word meaning "cairn of the cattle" or "cattle rocks". The Midland Railway line was constructed through the area in 1894, and a siding was built close to the Macpherson's homestead. This in turn led to further settlement of the area. The Carnamah Progress Association was formed in 1912, and the Carnamah State School was established, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
