Allocasuarina Microstachya
''Allocasuarina microstachya'' is a species of flowering plant in the family Casuarinaceae and is endemic to the south-west of Western Australia. It is dioecious shrub that has its leaves reduced to scales in whorls of four, the mature fruiting cones long containing winged seeds long. Description ''Allocasuarina microstachya'' is a dioecious, intricately-branched shrub that typically grows to a height of . Its branchlets are up to long, the leaves reduced to scale-like teeth long, arranged in whorls of four around the needle-like branchlets. The sections of branchlet between the leaf whorls are mostly long, wide and more or less square in cross-section. Male flowers are arranged in spikes long, the anthers long. Female cones are sessile, the mature cones shortly cylindrical to oval, long and in diameter containing black, hairy, winged seeds long.

Lawrence Alexander Sidney Johnson
Lawrence Alexander Sidney Johnson FAA, (26 June 1925 – 1 August 1997) known as Lawrie Johnson, was an Australian taxonomic botanist. He worked at the Royal Botanic Gardens, Sydney, for the whole of his professional career, as a botanist (1948–1972), Director (1972–1985) and Honorary Research Associate (1986–1997). - originally published in ''Historical Records of Australian Science'', vol.13, no.4, 2001. Alone or in collaboration with colleagues, he distinguished and described four new families of vascular plants, 33 new genera, 286 new species (including posthumous publications), and reclassified another 395 species. Of the families he described, Rhynchocalycaceae (with B. G. Briggs, 1985) is accepted by the Angiosperm Phylogeny Group (APG). Hopkinsiaceae and Lyginiaceae, (which he and B. G. Briggs proposed in 2000 be carved out of Anarthriaceae), have not been accepted by the APG. Lawrie Johnson died of cancer in 1997. He received many honours and awards, including ...

Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Described In 1845
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ability ...

Dioecious Plants
Dioecy (; ; adj. dioecious , ) is a characteristic of a species, meaning that it has distinct individual organisms (unisexual) that produce male or female gametes, either directly (in animals) or indirectly (in seed plants). Dioecious reproduction is biparental reproduction. Dioecy has costs, since only about half the population directly produces offspring. It is one method for excluding self-fertilization and promoting allogamy (outcrossing), and thus tends to reduce the expression of recessive deleterious mutations present in a population. Plants have several other methods of preventing self-fertilization including, for example, dichogamy, herkogamy, and self-incompatibility. Dioecy is a dimorphic sexual system, alongside gynodioecy and androdioecy. In zoology In zoology, dioecious species may be opposed to hermaphroditic species, meaning that an individual is either male or female, in which case the synonym gonochory is more often used. Most animal species are dioecious (gon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fagales Of Australia
The Fagales are an order of flowering plants, including some of the best-known trees. The order name is derived from genus ''Fagus'', beeches. They belong among the rosid group of dicotyledons. The families and genera currently included are as follows: *Betulaceae – birch family (''Alnus'', ''Betula'', ''Carpinus'', ''Corylus'', ''Ostrya'', ''Ostryopsis'') *Casuarinaceae – she-oak family (''Allocasuarina'', ''Casuarina'', ''Ceuthostoma'', ''Gymnostoma'') *Fagaceae – beech family ('' Castanea'', ''Castanopsis'', ''Chrysolepis'', ''Colombobalanus'', ''Fagus'', '' Lithocarpus'', ''Notholithocarpus'', ''Quercus'') *Juglandaceae – walnut family (''Alfaroa'', ''Carya'', ''Cyclocarya'', ''Engelhardia'', ''Juglans'', ''Oreomunnea'', ''Platycarya'', ''Pterocarya'', ''Rhoiptelea'') *Myricaceae – bayberry family (''Canacomyrica'', '' Comptonia'', ''Myrica'') *Nothofagaceae – southern beech family (''Nothofagus'') *Ticodendraceae – ticodendron family ('' Ticodendron'') The ...

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] |
Allocasuarina
''Allocasuarina'' is a genus of trees in the flowering plant family Casuarinaceae. They are endemic to Australia, occurring primarily in the south. Like the closely related genus ''Casuarina'', they are commonly called sheoaks or she-oaks. Wilson and Johnson distinguish the two very closely related genera, ''Casuarina'' and ''Allocasuarina'' on the basis of: *''Casuarina'': the mature samaras being grey or yellow-brown, and dull; cone bracteoles thinly woody, prominent, extending well beyond cone body, with no dorsal protuberance; *''Allocasuarina'': the mature samaras being red-brown to black, and shiny; cone bracteoles thickly woody and convex, mostly extending only slightly beyond cone body, and usually with a separate angular, divided or spiny dorsal protuberance. Description They are trees or shrubs that are notable for their long, segmented branchlets that function as leaves. Formally termed cladodes, these branchlets somewhat resemble pine needles, although sheoaks ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Department Of Biodiversity, Conservation And Attractions (Western Australia)
The Department of Biodiversity, Conservation and Attractions (DBCA) is the Government of Western Australia, Western Australian government department responsible for managing lands and waters described in the ''Conservation and Land Management Act 1984'', the ''Rottnest Island Authority Act 1987'', the ''Swan and Canning Rivers Management Act 2006'', the ''Botanic Gardens and Parks Authority Act 1998'', and the ''Zoological Parks Authority Act 2001'', and implementing the state's conservation and environment legislation and regulations.

The former DPaW became the Parks and Wildlife Service. Status Parks and Wildlife Service The Formerly the Depar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Munglinup River
The Munglinup River is an ephemeral river in the Goldfields-Esperance region of Western Australia. The headwaters of the river rise near Cheadanup Nature Reserve. It flows in a southerly direction through cleared farmland, then crossing the South Coast Highway near the town of Munglinup before discharging into the Oldfield River, of which it is a tributary, approximately from the coast. For most of the length of the river it is within a vegetated corridor, the surrounding land is mostly cleared for stock with only about 15% remnant vegetation remaining. The river only flows in the winter months and the water is naturally saline or brackish. The only tributary to the river is Clayhole Creek. The word Munglinup is Indigenous Australian in origin and of unknown meaning. The name was first recorded by C.D. Price, a surveyor Surveying or land surveying is the technique, profession, art, and science of determining the terrestrial two-dimensional or three-dimensional pos ...

Albany, Western Australia
Albany ( ; nys, Kinjarling) is a port city in the Great Southern region in the Australian state of Western Australia, southeast of Perth, the state capital. The city centre is at the northern edge of Princess Royal Harbour, which is a part of King George Sound. The central business district is bounded by Mount Clarence to the east and Mount Melville to the west. The city is in the local government area of the City of Albany. While it is the oldest colonial, although not European, settlement in Western Australia - predating Perth and Fremantle by over two years - it was a semi-exclave of New South Wales for over four years until it was made part of the Swan River Colony. The settlement was founded on 26 December 1826 as a military outpost of New South Wales for the purpose of forestalling French ambitions in the region. To that end, on 21 January 1827, the commander of the outpost, Major Edmund Lockyer, formally took possession for the British Crown of the portion of N ...
