Dandaragan, Western Australia
Dandaragan is a small town in the Wheatbelt region of Western Australia. The name of Dandaragan was first recorded in 1850 as the name of a nearby gulley and spring or watering hole known as Dandaraga spring. The word is Indigenous Australian in origin and is thought to mean ''good kangaroo country''. The first recorded land lease was to William Brockman in 1848; he had a land lease at Muchamulla Springs. James Drummond settled in the area in 1850 and established a farm. A police station was built later and the townsite was gazetted in 1958.

Stamen
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains ''sporangium, microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna (plant), Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea'' ...

Rosids Of Western Australia
The rosids are members of a large clade (monophyletic group) of flowering plants, containing about 70,000 species, more than a quarter of all angiosperms. The clade is divided into 16 to 20 orders, depending upon circumscription and classification. These orders, in turn, together comprise about 140 families. Fossil rosids are known from the Cretaceous period. Molecular clock estimates indicate that the rosids originated in the Aptian or Albian stages of the Cretaceous, between 125 and 99.6 million years ago. Today's forests are highly dominated by rosid species, which in turn helped with diversification in many other living lineages. Additionally, rosid herbs and shrubs are also a significant part of arctic/alpine, temperate floras, aquatics, desert plants, and parasites. Name The name is based upon the name "Rosidae", which had usually been understood to be a subclass. In 1967, Armen Takhtajan showed that the correct basis for the name "Rosidae" is a description of a group ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asterolasia
''Asterolasia'' is a genus of seventeen species of erect or prostrate shrubs in the family Rutaceae, and is endemic to Australia. The leaves are simple and arranged alternately, the flowers arranged in umbel-like groups on the ends of branchlets or in leaf axils, usually with five sepals, five petals and ten to twenty-five stamens. There are seventeen species and they are found in all Australian mainland states but not in the Northern Territory. Description Plants in the genus ''Asterolasia'' are erect or prostrate shrubs. They have simple leaves arranged alternately along the stems, and are simple with smooth edges. The flowers are bisexual and have five sepals, five petals and ten to twenty-five stamens. The sepals, petals and stamens are all free from each other, the stamens slightly shorter than the petals. There are five carpels fused at the base, sometimes to the tip usually with a small beak with the styles fused to each other with a shield-shaped stigma. The fruit is co ...

Declared Rare And Priority Flora List
The Declared Rare and Priority Flora List is the system by which Western Australia's conservation flora are given a priority. Developed by the Government of Western Australia's Department of Environment and Conservation, it was used extensively within the department, including the Western Australian Herbarium. The herbarium's journal, ''Nuytsia'', which has published over a quarter of the state's conservation taxa, requires a conservation status to be included in all publications of new Western Australian taxa that appear to be rare or endangered. The system defines six levels of priority taxa: ;X: Threatened (Declared Rare Flora) – Presumed Extinct Taxa: These are taxa that are thought to be extinct, either because they have not been collected for over 50 years despite thorough searching, or because all known wild populations have been destroyed. They have been declared as such in accordance with the Wildlife Conservation Act 1950, and are therefore afforded legislative protecti ...

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 ...

Nuytsia (journal)
''Nuytsia'' is a peer-reviewed scientific journal published by the Western Australian Herbarium. It publishes papers on systematic botany, giving preference to papers related to the flora of Western Australia. Nearly twenty percent of Western Australia's plant taxa have been published in ''Nuytsia''. The journal was established in 1970 and has appeared irregularly since. The editor-in-chief is Kevin Thiele. ''Nuytsia'' is named after the monospecific genus ''Nuytsia'', whose only species is '' Nuytsia floribunda'', the Western Australian Christmas tree. Occasionally, the journal has published special issues, such as an issue in 2007 substantially expanding described species from Western Australia. Publication details The record of the issues published is found at the ''FloraBase ''FloraBase'' is a public access web-based database of the flora of Western Australia. It provides authoritative scientific information on 12,978 taxa, including descriptions, maps, images, conservati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mount Lesueur
Mount Lesueur is a near-circular, flat-topped mesa located from Jurien Bay in Western Australia. It rises above the surrounding lateritic plain of Lesueur National Park which has eroded away around it. Mount Lesueur was first sighted and named by Europeans as the French ship the ''Naturaliste'' sailed past Jurien Bay on its voyage up the Western Australian coast. It was named in honour of Charles Alexander Lesueur, a natural history artist on board the ship. The next recorded sighting was by Captain George Grey Sir George Grey, KCB (14 April 1812 – 19 September 1898) was a British soldier, explorer, colonial administrator and writer. He served in a succession of governing positions: Governor of South Australia, twice Governor of New Zealand, Go ..., who led a small party through the area in 1839 after they were shipwrecked near Kalbarri. In 1849 a party led by A.C. Gregory ascended Mount Lesueur. They were followed the next year by botanical collector James Dru ...
