Acacia Pritzeliana
''Acacia pritzeliana'' is a shrub of the genus ''Acacia'' and the subgenus ''Phyllodineae'' that is endemic to south western Australia. Description The open shrub typically grows to a height of . It has light grey and scarred branches and hairy branchlets with spinose stipules that have a length of around . Like most species of ''Acacia'' it has phyllodes rather than true leaves. The crowded, rigid, pungent and evergreen phyllodes have a length of and a width of and are usually narrower near the apex with nerves that are rarely evident. It blooms from April to June and produces yellow flowers. Distribution It is native to an area in the Goldfields-Esperance region of Western Australia from south of Coolgardie in the north down to around Esperance in the south where it is commonly situated on flats and plains growing in sandy, clay or loamy soils. The distribution of the shrub extends as far as Cape Arid National Park Cape Arid National Park is a List of national parks ...

Australasian Virtual Herbarium
The ''Australasian Virtual Herbarium'' (AVH) is an online resource that allows access to plant specimen data held by various Australian and New Zealand herbaria. It is part of the Atlas of Living Australia (ALA), and was formed by the amalgamation of ''Australia's Virtual Herbarium'' and ''NZ Virtual Herbarium''. As of 12 August 2014, more than five million specimens of the 8 million and upwards specimens available from participating institutions have been databased. Uses This resource is used by academics, students, and anyone interested in research in botany in Australia or New Zealand, since each record tells all that is known about the specimen: where and when it was collected; by whom; its current identification together with the botanist who identified it; and information on habitat and associated species. ALA post processes the original herbarium data, giving further fields with respect to taxonomy and quality of the data. When interrogating individual specimen record ...

Acacia
''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] |
Endemism
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] |

Stipule
In botany, a stipule is an outgrowth typically borne on both sides (sometimes on just one side) of the base of a leafstalk (the petiole). Stipules are considered part of the anatomy of the leaf of a typical flowering plant, although in many species they may be inconspicuous —or sometimes entirely absent, and the leaf is then termed ''exstipulate''. (In some older botanical writing, the term "stipule" was used more generally to refer to any small leaves or leaf-parts, notably prophylls.) The word ''stipule'' was coined by Linnaeus''Concise English Dictionary'' Wordsworth Editions Ltd. 1994, from Latin ''stipula'', straw, stalk. Types of stipules General characteristics The position of stipules on a plant varies widely from species to species, though they are often located near the base of a leaf. Stipules are most common on dicotyledons, where they appear in pairs alongside each leaf. Some monocotyledon plants display stipule-like structures, but only display one per leaf ...

Phyllode
Phyllodes are modified petioles or leaf stems, which are leaf-like in appearance and function. In some plants, these become flattened and widened, while the leaf itself becomes reduced or vanishes altogether. Thus the phyllode comes to serve the purpose of the leaf. Some important examples are ''Euphorbia royleana'' which are cylindrical and '' Opuntia'' which are flattened. They are common in the genus ''Acacia'', especially the Australian species, at one time put in ''Acacia'' subg. ''Phyllodineae''. Sometimes, especially on younger plants, partially formed phyllodes bearing reduced leaves can be seen. The illustration (to the right) of ''Acacia suaveolens'' from ''Novae Hollandiae plantarum specimen'' shows the juvenile true leaves, together with the developing phyllodes, and the phyllodes of the mature plant. The genus, ''Daviesia'', in the family Fabaceae, is characterised in part by the plants having phyllodes. File:Acacia suaveolens 9064505997 9f14f5f117 o.jpg, ''Acacia ...

Coolgardie, Western Australia
Coolgardie is a small town in Western Australia, east of the state capital, Perth. It has a population of approximately 850 people. Although Coolgardie is now known to most Western Australians as a tourist town and a mining ghost town, it was once the third largest town in Western Australia (after Perth and Fremantle). At this time, mining of alluvial gold was a major industry and supplied the flagging economy with new hope. Many miners suffered under the harsh conditions, but for a few, their find made the hard work worthwhile. Most men, however, left poorer than they had started off, with their hopes dashed. History Coolgardie was founded in 1892, when gold was discovered in the area known as Fly Flat by prospectors Arthur Wellesley Bayley and William Ford. Australia had seen several major gold rushes over the previous three decades, mostly centred on the east coast, but these had mostly been exhausted by the 1890s. With the discovery of a new goldfield, an entire new ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Esperance, Western Australia
Esperance is a town in the Goldfields–Esperance region of Western Australia, on the Southern Ocean coastline approximately east-southeast of the state capital, Perth. The urban population of Esperance was 12,145 at June 2018. Its major industries are tourism, agriculture, and fishing. History European history of the region dates back to 1627 when the Dutch vessel ''Gulden Zeepaert'', skippered by François Thijssen, passed through waters off the Esperance coast and continued across the Great Australian Bight. French explorers are credited with making the first landfall near the present day town, naming it and other local landmarks while sheltering from a storm in this area in 1792. The town itself was named after a French ship, the ''Espérance'', commanded by Jean-Michel Huon de Kermadec. fr , Espérance , label=none is French for "hope". In 1802, British navigator Matthew Flinders sailed the Bay of Isles, discovering and naming places such as Lucky Bay and Thistle ...

Cape Arid National Park
Cape Arid National Park is a List of national parks of Australia, national park located in Western Australia, southeast of Perth. The park is situated east of Esperance, Western Australia, Esperance and lies on the shore of the South coast of Western Australia, south coast from the eastern end of the Recherche Archipelago. The bay at its eastern side is Israelite Bay, a locality often mentioned in Bureau of Meteorology weather reports as a geographical marker. The western end is known as Duke of Orleans Bay. Its coastline is defined by Cape Arid, a bay called Sandy Bight and, further east, Cape Pasley. History The first European to discover the area was the French Admiral Bruni D'Entrecasteaux in 1792 and he named it ''Cap Aride''; Matthew Flinders anglicized the name in 1802 and the park took its name from this feature. Pioneer Pastoral farming, graziers arrived in the area in the 1870s and the ruins of homesteads, dams and buildings as well as gravesites can be found near Pi ...

Eucalyptus
''Eucalyptus'' () is a genus of over seven hundred species of flowering trees, shrubs or mallees in the myrtle family, Myrtaceae. Along with several other genera in the tribe Eucalypteae, including '' Corymbia'', they are commonly known as eucalypts. Plants in the genus ''Eucalyptus'' have bark that is either smooth, fibrous, hard or stringy, leaves with oil glands, and sepals and petals that are fused to form a "cap" or operculum over the stamens. The fruit is a woody capsule commonly referred to as a "gumnut". Most species of ''Eucalyptus'' are native to Australia, and every state and territory has representative species. About three-quarters of Australian forests are eucalypt forests. Wildfire is a feature of the Australian landscape and many eucalypt species are adapted to fire, and resprout after fire or have seeds which survive fire. A few species are native to islands north of Australia and a smaller number are only found outside the continent. Eucalypts have been grow ...
