Pterostylis Insectifera
''Pterostylis insectifera'', commonly known as the insect-lipped rufous greenhood, or leaden rustyhood is a plant in the orchid family Orchidaceae and is endemic to the south-west of Western Australia. Both flowering and non-flowering plants have a relatively large rosette of leaves. Flowering plants have a similar rosette and up to eight or more flowers which have long, stiffly-held lateral sepals and a protruding, insect-like labellum. Description ''Pterostylis insectifera'' is a terrestrial, perennial, deciduous, herb with an underground tuber and a rosette of between five and twelve leaves. The leaves are long and wide. Flowering plants have a rosette at the base of the flowering stem but the leaves are usually withered by flowering time. Between two and eight or more translucent white, green and dark brown flowers long and wide are borne on a flowering spike tall. The dorsal sepal and petals form a hood or "galea" over the column with the dorsal sepal having ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

In 1935, The Dickson Report set forth a framework for their development. A large site fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Orchids Of 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pterostylis
''Pterostylis'' is a genus of about 300 species of plants in the orchid family, Orchidaceae. Commonly called greenhood orchids, they are terrestrial, deciduous, perennial, tuberous, herbs found in Australia, New Zealand, New Guinea, New Caledonia and one Indonesian island. The flowers are mostly green, sometimes with brown, reddish or white stripes, and are distinguished from other orchids by their unusual flower structures and pollination mechanism. Description Greenhood orchids are all terrestrial herbs with an underground tuber like many other genera of orchids but are distinguished by a hood-like "galea" formed by the fusing of the dorsal sepal and two lateral petals. The galea curves forward, covers the sexual parts of the flower, is important in the pollination process and is about as long as the two petals. The dorsal sepal is translucent white with green, reddish or brown stripes. The two lateral sepals are joined at their base, form the front of the flower and usually ...

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] |
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 ...

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.

Norseman, Western Australia
Norseman is a town located in the Goldfields-Esperance region of Western Australia along the Coolgardie-Esperance Highway, east of Perth and above sea level. It is also the starting point of the Eyre Highway, and the last major town in Western Australia before the South Australian border to the east. At the 2021 census, Norseman had a population of 562, of which 17% were Australian Aboriginal. History The quest for gold led to the establishment of Norseman, on the traditional land of the Ngadju. Today there are a number of small goldmining operations in the area but only the Central Norseman Gold Corporation can be considered a major producer. Gold was first found in the Norseman area in 1892, about 10 km south of the town, near Dundas. The "Dundas Field" was proclaimed in August 1893 and a townsite gazetted there. In August 1894, Lawrence Sinclair, his brother George Sinclair, and Jack Alsopp discovered a rich gold reef which Sinclair named after his horse, Hardy Nor ...

Ravensthorpe, Western Australia
Ravensthorpe is a town 541 km south-east of Perth and 40 km inland from the south coast of Western Australia. It is the seat of government of the Shire of Ravensthorpe. At the , Ravensthorpe had a population of 438. In 1848, the area was surveyed by Surveyor General John Septimus Roe who named many of the geographical features nearby, including the nearby Ravensthorpe Range that the later town was named after. There was one of the Western Australian Government Railways isolated branch lines between Hopetoun and Ravensthorpe. This line opened in 1909. Alluvial gold was discovered at the Phillips River in 1892. At the goldfield a ''de facto'' town emerged, known as ''Phillips River''. The government completed construction of a copper and gold smelter about 2 km south east of the town in 1906, used to cast copper and gold ingots. History A temporary pastoral lease ("Free Run") was registered by James Dunn senior in 1868. His five sons and daughter started she ...
