Calectasia Obtusa
''Calectasia obtusa'', commonly known as a blue tinsel lily or blunt-leaved tinsel lily is a plant in the family Dasypogonaceae growing as an erect, small shrub with stems to 50 cm. It is endemic to the south-west of Western Australia, widespread in most of its range but only known from nine populations. Description ''Calectasia obtusa'' is an undershrub with stilt roots 30–55 mm long but no rhizome. It grows to a height of about 50 cm with several short side branches. Each leaf blade is glabrous except at the margins, 4.5–8.5 x 0.5–0.9 mm, often pressed against the stem, the ends usually blunt and only rarely tapering to a short, sharp point. The base of the petals (strictly tepals) form a tube 7.7–8.8 mm long, while the outer part of the petals are wine red with blue margins fading to pale blue with age and spreading outwards to form a papery, star-like pattern. In the centre of the star are six yellow stamens forming a tub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hopetoun, Western Australia
Hopetoun is a town on the south coast of Western Australia in the Shire of Ravensthorpe. Located on Mary Ann Harbour, Hopetoun is south-east from capital city Perth and west of Esperance. History Mary Ann Harbour was named in November 1865 by the sealer James Sale on the cutter ''Mary Ann''. The ''Mary Ann'' was owned by whaling master John Thomas of Cheyne's Beach, east of Albany, who had named it after his eldest daughter. Hopetoun was established in 1900 as the port servicing the Phillips River goldfield, named after the first Governor-General of Australia, John Hope, 7th Earl of Hopetoun. The townsite was gazetted on 9 February 1901. The town became a shipping port for the mining industry, with a jetty built in 1901, the terminus of a railway line between Hopetoun and Ravensthorpe that operated from 1909 to 1935. The port was closed in 1937, with the jetty remaining until its destruction in 1983. Some of the town's electricity is generated by a wind-diesel system. ...

Commelinids Of Australia
In plant taxonomy, commelinids (originally commelinoids) (plural, not capitalised) is a clade of flowering plants within the monocots, distinguished by having cell walls containing ferulic acid. The commelinids are the only clade that the APG IV system has informally named within the monocots. The remaining monocots are a paraphyletic unit. Also known as the commelinid monocots it forms one of three groupings within the monocots, and the final branch; the other two groups are the alismatid monocots and the lilioid monocots. Description Members of the commelinid clade have cell walls containing UV-fluorescent ferulic acid. Taxonomy The commelinids were first recognized as a formal group in 1967 by Armen Takhtajan, who named them the Commelinidae and assigned them to a subclass of Liliopsida (monocots). The name was also used in the 1981 Cronquist system. However, by the release of his 1980 system of classification, Takhtajan had merged this subclass into a larger one, and no ...

Endemic Flora Of Western Australia
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laterite
Laterite is both a soil and a rock type rich in iron and aluminium and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock, usually when there are conditions of high temperatures and heavy rainfall with alternate wet and dry periods. Tropical weathering (''laterization'') is a prolonged process of chemical weathering which produces a wide variety in the thickness, grade, chemistry and ore mineralogy of the resulting soils. The majority of the land area containing laterites is between the tropics of Cancer and Capricorn. Laterite has commonly been referred to as a soil type as well as being a rock type. This and further variation in the modes of conceptualizing about laterite (e.g. also as a complete weathering profile or theory about weathering) has led to calls for the term to be abandoned alto ...

Heath
A heath () is a shrubland habitat found mainly on free-draining infertile, acidic soils and characterised by open, low-growing woody vegetation. Moorland is generally related to high-ground heaths with—especially in Great Britain—a cooler and damper climate. Heaths are widespread worldwide but are fast disappearing and considered a rare habitat in Europe. They form extensive and highly diverse communities across Australia in humid and sub-humid areas where fire regimes with recurring burning are required for the maintenance of the heathlands.Specht, R.L. 'Heathlands' in 'Australian Vegetation' R.H. Groves ed. Cambridge University Press 1988 Even more diverse though less widespread heath communities occur in Southern Africa. Extensive heath communities can also be found in the Texas chaparral, New Caledonia, central Chile, and along the shores of the Mediterranean Sea. In addition to these extensive heath areas, the vegetation type is also found in scattered locations acro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Woodland
A woodland () is, in the broad sense, land covered with trees, or in a narrow sense, synonymous with wood (or in the U.S., the ''plurale tantum'' woods), a low-density forest forming open habitats with plenty of sunlight and limited shade (see differences between British, American, and Australian English explained below). Woodlands may support an understory of shrubs and herbaceous plants including grasses. Woodland may form a transition to shrubland under drier conditions or during early stages of primary or secondary succession. Higher-density areas of trees with a largely closed canopy that provides extensive and nearly continuous shade are often referred to as forests. Extensive efforts by conservationist groups have been made to preserve woodlands from urbanization and agriculture. For example, the woodlands of Northwest Indiana have been preserved as part of the Indiana Dunes. Definitions United Kingdom ''Woodland'' is used in British woodland management to mean tre ...

Loam
Loam (in geology and soil science) is soil composed mostly of sand (particle size > ), silt (particle size > ), and a smaller amount of clay (particle size < ). By weight, its mineral composition is about 40–40–20% concentration of sand–silt–clay, respectively. These proportions can vary to a degree, however, and result in different types of loam soils: sandy loam, silty loam, clay loam, sandy clay loam, silty clay loam, and loam. In the , textural classification triangle, the only soil that is not predominantly sand, silt, or clay is called "loam". Loam soils generally contain more nutrients, moisture, and |
Southwest Australia
Southwest Australia is a biogeographic region in Western Australia. It includes the Mediterranean-climate area of southwestern Australia, which is home to a diverse and distinctive flora and fauna. The region is also known as the Southwest Australia Global Diversity Hotspot, as well as Kwongan. Geography The region includes the Mediterranean forests, woodlands, and scrub ecoregions of Western Australia. The region covers 356,717 km2, consisting of a broad coastal plain 20-120 kilometres wide, transitioning to gently undulating uplands made up of weathered granite, gneiss and laterite. Bluff Knoll in the Stirling Range is the highest peak in the region, at 1,099 metres (3,606 ft) elevation. Desert and xeric shrublands lie to the north and east across the centre of Australia, separating Southwest Australia from the other Mediterranean and humid-climate regions of the continent. Climate The region has a wet-winter, dry-summer Mediterranean climate, one of five such regio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kojonup, Western Australia
Kojonup is a town south-east of Perth, Western Australia along Albany Highway in the Great Southern (Western Australia), Great Southern region. The name Kojonup refers to the "Kodja" or stone axe made by Aboriginal Australians, from the local stone. History The Noongar people are the traditional owners and inhabitants of Kojonup. Specifically, the Noongar people of Kojonup today are descendants of the Kaneang language group and their neighbours, such as the Koreng, Pinjareb and Menang. Historically the Noongar people drank from the local freshwater spring and hunted game with the traditional Noongar "kodj", or stone axe. Both Kojonup and The Kodja Place are named after the historically significant implement. The first European in the area was surveyor Alfred Hillman who arrived in 1837 and had been guided to freshwater spring by the Noongar people. The site was an important staging place on the road to Albany, Western Australia, Albany, and in 1837 a military post was establishe ...

Dasypogonaceae
Dasypogonaceae is a family of flowering plants, one that has not been commonly recognized by taxonomists; the plants it contains were usually included in the family Xanthorrhoeaceae. If valid, Dasypogonaceae includes four genera with 16 species. The 2016 APG IV system places the family in the order Arecales, after several studies revealed the family as a sister-family to Arecaceae. The earlier APG III (2009), APG II (2003), and the 1998 APG system all accepted the validity of the family, assigning it to the clade commelinids, but leaving it unplaced as to order. The commelinids are monocots, the broad group to which, in any event, these plant clearly belong. The family is endemic to Australia, and comprises 16 species in four genera. The best known representative is ''Kingia australis ''Kingia'' is a genus consisting of a single species, ''Kingia australis'', and belongs to the plant family Dasypogonaceae. The Aboriginal name bullanock is used as a common name for the plant. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Riche
Cape Riche is a cape and rural locality in the Great Southern region of Western Australia. By road, it is 525 km south-east of Perth and 123 km north-east of Albany Facilities in the locality include a boat launching ramp and a campground with flushing toilets and showers. History Cape Riche was named for Claude-Antoine-Gaspard Riche, a naturalist on Bruni d'Entrecasteaux's 1791 expedition who became lost for two days near Esperance. Matthew Flinders aboard the '' Investigator'' charted the area in 1802 as part of his circumnavigation of Australia. George Cheyne, a Scottish immigrant, took up land at Cape Riche in 1836, after arriving in Albany in 1831. He established a trading post which was often visited by American whalers. In about 1848, sandalwood cutters arrived in the area, The Surveyor-General of Western Australia, John Septimus Roe, visited the Cape in October 1848 as part of this 1848–49 expedition and reorganised his supplies while staying wit ...
