''Allocasuarina humilis'', commonly known as dwarf sheoak, is a species of flowering plant in the family Casuarinaceae and is endemic to the Southwest Australia, south-west of Western Australia. It is an erect or spreading Dioecy, dioecious or Monoecy, monoecious shrub that has its leaves reduced to scales in Whorl (botany), whorls of five to seven, the mature fruiting cones long containing winged seeds (samaras) long.

Christoph Friedrich Otto
Christoph Friedrich Otto (4 December 1783 – 7 December 1856) was a German gardener and botanist. He was born in Schneeberg, Saxony. From 1805 to 1843 he was inspector of the Botanical Garden in Berlin. Together with Albert Gottfried Dietrich (1795–1856), he edited the ''Allgemeinen Gartenzeitung'' from 1833 until his death in 1856 in Berlin. The genus of plants '' Ottoa'' H. B. K. is named after him. As a taxonomist, he was the binomial authority/co-authority of many species, including numerous plants within the family Cactaceae.

Journal Of The Adelaide Botanic Gardens
The Adelaide Botanic Garden is a public garden at the north-east corner of the Adelaide city centre, in the Adelaide Park Lands. It encompasses a fenced garden on North Terrace (between Lot Fourteen, the site of the old Royal Adelaide Hospital, and the National Wine Centre) and behind it the Botanic Park (adjacent to the Adelaide Zoo). Work was begun on the site in 1855, with its official opening to the public on 4 October 1857. The Adelaide Botanic Garden and adjacent State Herbarium of South Australia, together with the Wittunga Botanic Garden and Mount Lofty Botanic Garden, comprise the Botanic Gardens and State Herbarium of South Australia, administered by the Board of the Botanic Gardens and State Herbarium, a state government statutory authority. History From the first official survey carried out for the map of Adelaide, Colonel William Light intended for the planned city to have a "botanical garden". To this end, he designated a naturally occurring ait that had for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fagales Of Australia
The Fagales are an order of flowering plants in the rosid group of dicotyledons, including some of the best-known trees. Well-known members of Fagales include: beeches, chestnuts, oaks, walnut, pecan, hickory, birches, alders, hazels, hornbeams, she-oaks, and southern beeches. The order name is derived from genus ''Fagus'' (beeches). Systematics Fagales include the following seven families, according to the APG III system of classification: *Betulaceae – birch family (''Alnus'', ''Betula'', ''Carpinus'', ''Corylus'', ''Ostrya'', and ''Ostryopsis'') *Casuarinaceae – she-oak family (''Allocasuarina'', ''Casuarina'', ''Ceuthostoma'', and ''Gymnostoma'') *Fagaceae – beech family (''Castanea'', ''Castanopsis'', ''Chrysolepis'', ''Fagus'', ''Lithocarpus'', ''Notholithocarpus'', ''Quercus'', and '' Trigonobalanus'') *Juglandaceae – walnut family (''Alfaroa'', ''Carya'', '' Cyclocarya'', '' Engelhardia'', ''Juglans'', ''Oreomunnea'', ''Platycarya'', ''Pterocarya'', and ''Rhoi ...

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 may have originated in the Aptian or Albian stages of the Cretaceous, between 125 and 99.6 million years ago. Today's broadleaved forests are dominated by rosid species, which in turn help with diversification in many other living lineages. Additionally, rosid herbs and shrubs are a significant part of arctic/alpine and temperate floras. The clade also includes some aquatic, desert and parasitic plants. 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 na ...

Laterite
Laterite is a soil 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. The process of formation is called laterization. Tropical weathering 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 ...

Murchison River (Western Australia)
The Murchison River is the second longest river in Western Australia. It flows for about from the southern edge of the Robinson Ranges to the Indian Ocean at Kalbarri. The Murchison-Yalgar-Hope river system is the longest river system in Western Australia. It has a mean annual flow of 208 gigalitres, although in 2006, the peak year on record since 1967, flow was 1,806gigalitres. Basin The Murchison River basin covers an area of about in the Mid West region of Western Australia. It extends about inland from the Indian Ocean, onto the Yilgarn craton east of Meekatharra and north of Sandstone. Rain generally falls in the upper basin during summer cyclones, so for much of the year the Murchison River does not flow, leaving a dry sandy river bed and intermittent permanent pools. The eastern reaches of the basin contain large chains of salt lakes, which flow only following rainfall. The drainage lines from these lakes merge to form the Murchison River about north-north ...

Allocasuarina Decussata
''Allocasuarina decussata'', commonly known as karri oak or karri she-oak, is a species of flowering plant in the family Casuarinaceae and is endemic to the southwest of Western Australia. It is an understory tree in karri forest but also occurs as a stunted shrub in places like Bluff Knoll in the Stirling Range. Description Karri oak usually grows as a medium tree high, although in harsh, exposed situations in places like the top of Bluff Knoll it is a stunted shrub or poorly-formed tree in shrubland. As with other members of the family Casuarinaceae, the foliage consists of wiry green branchlets called cladodes with rings of minute leaf scales. In this species, the branchlets are about long, roughly square or X-shaped in cross section, with four scale-teeth in each ring. The rings of scale-leaves are apart. Separate male and female flowers form on the same individual plant. The fruiting structure is a woody cone, shaped like a short cylinder with its diameter roughly equ ...

Binomial Name
In taxonomy, binomial nomenclature ("two-term naming system"), also called 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 (often shortened to just "binomial"), a binomen, name, or a scientific name; more informally, it is also called a Latin name. In the International Code of Zoological Nomenclature (ICZN), the system is also called nomenclature, with an "n" before the "al" in "binominal", which is a typographic error, meaning "two-name naming system". 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 ''Hom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
