Isopogon Asper
''Isopogon asper'' is a species of plant in the family Proteaceae and is endemic to the south-west of Western Australia. It is a low shrub with crowded pinnate leaves and flattened spherical heads of glabrous pink flowers. Description ''Isopogon asper'' is a shrub that typically grows to a height of and has hairy reddish-brown branchlets. The leaves are crowded, up to about long and pinnate with cylindrical or grooved leaflets on a petiole up to about long. The flowers are arranged in sessile, densely clustered, flattened-spherical heads up to in diameter. The involucral bracts are egg-shaped and pointed and the flowers are about long, pink and glabrous. Flowering occurs from June to October and the fruit is a hairy nut, fused in a spherical head up to in diameter. Taxonomy ''Isopogon asper'' was first formally described in 1830 by Robert Brown in the '' Supplementum'' to his ''Prodromus Florae Novae Hollandiae et Insulae Van Diemen'' from specimens collected in 1827 n ...

Robert Brown (botanist, Born 1773)
Robert Brown (21 December 1773 – 10 June 1858) was a Scottish botanist and paleobotanist who made important contributions to botany largely through his pioneering use of the microscope. His contributions include one of the earliest detailed descriptions of the cell nucleus and cytoplasmic streaming; the observation of Brownian motion; early work on plant pollination and fertilisation, including being the first to recognise the fundamental difference between gymnosperms and angiosperms; and some of the earliest studies in palynology. He also made numerous contributions to plant taxonomy, notably erecting a number of plant families that are still accepted today; and numerous Australian plant genera and species, the fruit of his exploration of that continent with Matthew Flinders. Early life Robert Brown was born in Montrose on 21 December 1773, in a house that existed on the site where Montrose Library currently stands. He was the son of James Brown, a minister in the ...

Nut (fruit)
A nut is a fruit consisting of a hard or tough nutshell protecting a kernel which is usually edible. In general usage and in a culinary sense, a wide variety of dry seeds are called nuts, but in a botanical context "nut" implies that the shell does not open to release the seed (indehiscent). Most seeds come from fruits that naturally free themselves from the shell, but this is not the case in nuts such as hazelnuts, chestnuts, and acorns, which have hard shell walls and originate from a compound ovary. The general and original usage of the term is less restrictive, and many nuts (in the culinary sense), such as almonds, pecans, pistachios, walnuts, and Brazil nuts, are not nuts in a botanical sense. Common usage of the term often refers to any hard-walled, edible kernel as a nut. Nuts are an energy-dense and nutrient-rich food source. Botanical definition A seed is the mature fertilised ovule of a plant; it consists of three parts, the embryo which will develop into a ne ...

Eudicots Of Western Australia
The eudicots, Eudicotidae, or eudicotyledons are a clade of flowering plants mainly characterized by having two seed leaves upon germination. The term derives from Dicotyledons. Traditionally they were called tricolpates or non-magnoliid dicots by previous authors. The botanical terms were introduced in 1991 by evolutionary botanist James A. Doyle and paleobotanist Carol L. Hotton to emphasize the later evolutionary divergence of tricolpate dicots from earlier, less specialized, dicots. Numerous familiar plants are eudicots, including many common food plants, trees, and ornamentals. Some common and familiar eudicots include sunflower, dandelion, forget-me-not, cabbage, apple, buttercup, maple, and macadamia. Most leafy trees of midlatitudes also belong to eudicots, with notable exceptions being magnolias and tulip trees which belong to magnoliids, and ''Ginkgo biloba'', which is not an angiosperm.

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] |
Isopogon
''Isopogon'', commonly known as conesticks, conebushes or coneflowers, is a genus of about forty species of flowering plants in the family Proteaceae, and are endemic to Australia. They are shrubs with rigid leaves, bisexual flowers in a dense spike or "cone" and the fruit is a small, hairy nut. Description Plants in the genus ''Isopogon'' are erect or prostrate shrubs with rigid, usually compound, rarely simple leaves. Compound leaves are deeply divided with flat or cylindrical lobes. The flowers are usually arranged on the ends of branches, usually surrounded by bracts, in a more or less conical or spherical spike. Each flower is bisexual and symmetrical, the tepals spreading as the flower develops, the lower part persisting unit the fruit expands. The fruit are fused to form a woody cone-like to more or less spherical structure, each fruit a nut with bracts that eventually fall and release the fruit. ''Isopogon'' have 13 haploid chromosomes.

Jurien Bay, Western Australia
Jurien Bay is a coastal town in the Wheatbelt region of Western Australia, north of Perth facing the Indian Ocean. History The coastline around Jurien Bay was first known to Europeans in the 17th century. In 1801–03, an expedition under the command of Nicolas Baudin sailed along the Western Australian coast. Louis de Freycinet, a cartographic surveyor on the expedition, named Jurien Bay after Charles Marie Jurien (1763–1836) of the French naval administration. The area was visited by a number of English explorers from 1822 onwards. The bay was first surveyed by Captain James Harding, the harbourmaster of Fremantle, in 1865, with a more extensive survey made by Staff Commander W. E. Archdeacon R.N. in 1875. The first settlement was established in the mid-1850s by Walter Padbury. A jetty was constructed in 1885–87 due to the success of pastoralism. In the early 1900s, a temporary fishing village was built around the Jurien jetty and the coastal waters were used for catchi ...

Harvey, Western Australia
Harvey is a town located in the South West of Western Australia along the South Western Highway, south of Perth, between Pinjarra and Bunbury. It has a population of 2,750. Harvey Town is known for its dairy industry and oranges. History Harvey's name is derived from the nearby Harvey River, named by Governor James Stirling in 1829, soon after the river's discovery by explorers Alexander Collie and Lieutenant William Preston RN. Although not positively known, the river is most likely named after Rear Admiral John Harvey. In 1817–18, Harvey was Commander in Chief of the West Indies StationStirling served under him while in charge of , and Harvey recommended him for promotion. Stirling named a number of Western Australian features after his former navy colleagues. According to James Battye, Stirling selected known as Wellington Location 50A and established the Harvey River Settlement. The only improvement he made to the land, as far as is known, was the erection of a hunti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Fraser (botanist)
Charles Fraser or Frazer or Frazier (1788 – 22 December 1831) was Colonial Botanist of New South Wales from 1821 to 1831. He collected and catalogued numerous Australian plant species, and participated in a number of exploring expeditions. He was a member of the Stirling expedition of 1827, and his report on the quality of the soil was instrumental in the decision to establish the Swan River Colony. Early life and army career Charles Fraser was born in Blair Atholl, Perthshire, Scotland in 1788. He worked as a gardener, probably for the extensive estates of the landlord, the Duke of Atholl, and subsequently had connections with the botanic gardens of Edinburgh and Glasgow.Davies G (2002).

Swan River (Western Australia)
The Swan River () is a river in the south west of Western Australia. The river runs through the metropolitan area of Perth, Western Australia's capital and largest city. Course of river The Swan River estuary flows through the city of Perth. Its lower reaches are relatively wide and deep, with few constrictions, while the upper reaches are usually quite narrow and shallow. The Swan River drains the Avon and coastal plain catchments, which have a total area of about . It has three major tributaries, the Avon River, Canning River and Helena River. The latter two have dams (Canning Dam and Mundaring Weir) which provide a sizeable part of the potable water requirements for Perth and the regions surrounding. The Avon River contributes the majority of the freshwater flow. The climate of the catchment is Mediterranean, with mild wet winters, hot dry summers, and the associated highly seasonal rainfall and flow regime. The Avon rises near Yealering, southeast of Perth: it meand ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prodromus Florae Novae Hollandiae Et Insulae Van Diemen
''Prodromus Florae Novae Hollandiae et Insulae Van Diemen'' (Prodromus of the Flora of New Holland and Van Diemen's Land) is a flora of Australia written by botanist Robert Brown and published in 1810. Often referred to as ''Prodromus Flora Novae Hollandiae'', or by its standard botanical abbreviation ''Prodr. Fl. Nov. Holland.'', it was the first attempt at a survey of the Australian flora. It described over 2040 species, over half of which were published for the first time. Brown's ''Prodromus'' was originally published as Volume One, and following the ''Praemonenda'' (Preface), page numbering commences on page 145. Sales of the ''Prodromus'' were so poor, however, that Brown withdrew it from sale. Due to the commercial failure of the first volume, pages 1 to 144 were never issued, and Brown never produced the additional volumes that he had planned. In 1813, a book of illustrations for the ''Prodromus'' was published separately by Ferdinand Bauer under the title ''Ferdinandi Ba ...
