Astroloma Pallidum
''Astroloma pallidum'', commonly known as kick bush, is usually a small, compact shrub in the family Ericaceae. The species is endemic to south-western Western Australia. Description ''Astroloma pallidum'' is usually a neat, dense, compact shrub but sometimes a diffuse to erect shrub to about 30 cm high. The leaves are lance-shaped, about long with toothed margins. Creamy white to pale yellow (rarely pink or red) tubular flowers are present in the axils of leaves for most of the year. Taxonomy and naming ''Astroloma pallidum'' was first described by Robert Brown in 1810 in ''Prodromus Florae Novae Hollandiae''. The specific epithet (''pallidum'') is a Latin word meaning "pale" or "wan". Distribution and habitat Kick bush grows on yellow/grey sand, red/brown laterite gravel, brown clay to sandy clay, ironstone and limestone in a variety of habitats including flats, hillslopes, winter-wet sites and the edges of lakes in the Avon Wheatbelt, Esperance Plains, Geraldton Sand ...

Darling Scarp
The Darling Scarp, also referred to as the Darling Range or Darling Ranges, is a low escarpment running north–south to the east of the Swan Coastal Plain and Perth, Western Australia. The escarpment extends generally north of Bindoon, to the south of Pemberton. The adjacent Darling Plateau goes easterly to include Mount Bakewell near York and Mount Saddleback near Boddington. It was named after the Governor of New South Wales, Lieutenant-General Ralph Darling. History The feature was first recorded as General Darling Range by Charles Fraser, Government Botanist with Captain James Stirling aboard in March 1827. Maps from the 1830s show the scarp labelled " General Darlings Range"; this later became Darling Range, a name by which the formation was still commonly known in the late 20th century despite common understanding of it being an escarpment. There is also a tendency to identify the locations on or to the east of the scarp as being in the "Perth Hills" (or simpl ...

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] |
Ericales Of Australia
The Ericales are a large and diverse order of dicotyledons. Species in this order have considerable commercial importance including for tea, persimmon, blueberry, kiwifruit, Brazil nuts, argan, and azalea. The order includes trees, bushes, lianas, and herbaceous plants. Together with ordinary autophytic plants, the Ericales include chlorophyll-deficient mycoheterotrophic plants (e.g., '' Sarcodes sanguinea'') and carnivorous plants (e.g., genus ''Sarracenia''). Many species have five petals, often grown together. Fusion of the petals as a trait was traditionally used to place the order in the subclass Sympetalae. Mycorrhizal associations are quite common among the order representatives, and three kinds of mycorrhiza are found exclusively among Ericales (namely, ericoid, arbutoid and monotropoid mycorrhiza). In addition, some families among the order are notable for their exceptional ability to accumulate aluminum. Ericales are a cosmopolitan order. Areas of distribution of fa ...

Astroloma
''Astroloma'' is an endemic Australian genus of around 20 species of flowering plants in the family Ericaceae. The majority of the species are endemic to Western Australia, but a few species occur in New South Wales, Victoria, Tasmania and South Australia. The genus was first described by Robert Brown in 1810 in Prodromus Florae Novae Hollandiae. The name ''Astroloma'' is derived from the Ancient Greek words ''astron'' = a star and ''loma'' = a fringe, alluding to five tufts of hairs which form a star at the bottom of the inside of the floral tube. Species include: *'' Astroloma baxteri'' A.Cunn. ex DC. *'' Astroloma cataphractum'' A.J.G.Wilson MS *'' Astroloma ciliatum'' (Lindl.)

IBRA
The Interim Biogeographic Regionalisation for Australia (IBRA) is a biogeographic regionalisation of Australia developed by the Australian government's Department of Sustainability, Environment, Water, Population, and Communities. It was developed for use as a planning tool, for example for the establishment of a national reserve system. The first version of IBRA was developed in 1993–94 and published in 1995. Within the broadest scale, Australia is a major part of the Australasia biogeographic realm, as developed by the World Wide Fund for Nature. Based on this system, the world is also split into 14 terrestrial habitats, of which eight are shared by Australia. The Australian land mass is divided into 89 bioregions and 419 subregions. Each region is a land area made up of a group of interacting ecosystems that are repeated in similar form across the landscape. IBRA is updated periodically based on new data, mapping improvements, and review of the existing scheme. The most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Warren (biogeographic Region)
Warren, also known as Karri Forest Region and the Jarrah-Karri forest and shrublands ecoregion, is a biogeographic region in southern Western Australia. Located in the southwest corner of Western Australia between Cape Naturaliste and Albany, it is bordered to the north and east by the Jarrah Forest region. Its defining characteristic is an extensive tall forest of ''Eucalyptus diversicolor'' (karri). This occurs on dissected, hilly ground, with a moderately wet climate. Karri is a valuable timber and much of the karri forest has been logged over, but less than a third has been cleared for agriculture. Recognised as a region under the Interim Biogeographic Regionalisation for Australia (IBRA), and as a terrestrial ecoregion by the World Wide Fund for Nature, it was first defined by Ludwig Diels in 1906. Geography and geology The Warren region is defined as the coastal sandplain between Cape Naturaliste and Albany. Extending from the ocean to the edge of the Yilgarn craton p ...

Mallee (biogeographic Region)
Mallee, also known as Roe Botanical District, is a biogeographic region in southern Western Australia. Located between the Esperance Plains, Avon Wheatbelt and Coolgardie bioregions, it has a low, gently undulating topography, a semi-arid mediterranean climate, and extensive ''Eucalyptus'' mallee vegetation. It has an area of . About half of the region has been cleared for intensive agriculture. Recognised as a region under the Interim Biogeographic Regionalisation for Australia (IBRA), it was first defined by John Stanley Beard in 1980. Geography and geology The Mallee region has a complex shape with tortuous boundaries, but may be roughly approximated as the triangular area south of a line from Bruce Rock to Eyre, but not within 40 kilometres (25 mi) of the south coast, except at its eastern limits. It has an area of about 79000 square kilometres (31000 mi²), making it about a quarter of the South West Botanic Province, 3% of the state, and 1% of Australia. It ...

Jarrah Forest
Jarrah forest is tall open forest in which the dominant overstory tree is ''Eucalyptus marginata'' (jarrah). The ecosystem occurs only in the Southwest Botanical Province of Western Australia. It is most common in the biogeographic region named in consequence Jarrah Forest. Most jarrah forest contains at least one other co-dominant overstory tree; association with ''Corymbia calophylla'' is especially common, and results in which is sometimes referred to as jarrah-marri forest.

Avon Wheatbelt
The Avon Wheatbelt is a bioregion in Western Australia. It has an area of . It is considered part of the larger Southwest Australia savanna ecoregion. Geography The Avon Wheatbelt bioregion is mostly a gently undulating landscape with low relief. It lies on the Yilgarn Craton, an ancient block of crystalline rock, which was uplifted in the Tertiary and dissected by rivers. The craton is overlain by laterite deposits, which in places have decomposed into yellow sandplains, particularly on low hills. Steep-sided erosional gullies, known as breakaways, are common.
