Eucalyptus Wyolensis
''Eucalyptus wyolensis'', commonly known as the Wyola mallee, is a species of mallee that is endemic to South Australia. It has rough bark on the base of the stems, smooth grey to brown bark above, heart-shaped to egg-shaped adult leaves arranged in opposite pairs, flower buds in groups of seven to eleven, pale yellow flowers and cup-shaped to barrel-shaped fruit. Description ''Eucalyptus wyolensis'' is a mallee that typically grows to a height of and forms a lignotuber. The bark is rough and fibrous on the base of the trunk, sometimes to the larger branches, and smooth grey to brown or cream-coloured above. Young plants and coppice regrowth have stems that are square in cross-section, glaucous and heart-shaped, long and wide. Adult leaves are similar to the juvenile leaves, heart-shaped to egg-shaped, the same glaucous green on both sides, sessile, long and wide. The flowers buds are arranged in leaf axils in groups of seven, nine or eleven on an unbranched peduncle lon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Journal Of The Adelaide Botanic Garden
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 of South Australia'', administered by the Board of the Botanic Gardens and State Herbarium, a state government statutory authority. Early 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 formed in the cour ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of South Australia
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myrtales Of Australia
The Myrtales are an order of flowering plants placed as a sister to the eurosids II clade as of the publishing of the ''Eucalyptus grandis'' genome in June 2014. The APG III system of classification for angiosperms still places it within the eurosids. This finding is corroborated by the placement of the Myrtales in the Malvid clade by the One Thousand Plant Transcriptomes Initiative. The following families are included as of APGIII: * Alzateaceae S. A. Graham * Combretaceae R. Br. ( leadwood family) * Crypteroniaceae A. DC. * Lythraceae J. St.-Hil. ( loosestrife and pomegranate family) * Melastomataceae Juss. (including Memecylaceae DC.) * Myrtaceae Juss. (myrtle family; including Heteropyxidaceae Engl. & Gilg, Psiloxylaceae Croizat) * Onagraceae Juss. (evening primrose and Fuchsia family) * Penaeaceae Sweet ex Guill. (including Oliniaceae Arn., Rhynchocalycaceae L. A. S. Johnson & B. G. Briggs) * Vochysiaceae A. St.-Hil. The Cronquist system gives essentially the same co ...

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 ...

Near Threatened Species
A near-threatened species is a species which has been categorized as "Near Threatened" (NT) by the International Union for Conservation of Nature as that may be vulnerable to endangerment in the near future, but it does not currently qualify for the threatened status. The IUCN notes the importance of re-evaluating near-threatened taxon at appropriate intervals. The rationale used for near-threatened taxa usually includes the criteria of vulnerable which are plausible or nearly met, such as reduction in numbers or range. Near-threatened species evaluated from 2001 onwards may also be ones which are dependent on conservation efforts to prevent their becoming threatened, whereas before this conservation-dependent species were given a separate category ("Conservation Dependent"). Additionally, the 402 conservation-dependent taxa may also be considered near-threatened.

International Union For The Conservation Of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Victoria Desert
The Great Victoria Desert is a sparsely populated desert ecoregion and interim Australian bioregion in Western Australia and South Australia. History In 1875, British-born Australian explorer Ernest Giles became the first European to cross the desert. He named the desert after the then-reigning monarch, Queen Victoria. In 1891, David Lindsey's expedition traveled across this area from north to south. Frank Hann was looking for gold in this area between 1903 and 1908. Len Beadell explored the area in the 1960s. Location and description The Great Victoria is the largest desert in Australia, and consists of many small sandhills, grassland plains, areas with a closely packed surface of pebbles (called desert pavement or gibber plains), and salt lakes. It is over wide (from west to east) and covers an area of from the Eastern Goldfields region of Western Australia to the Gawler Ranges in South Australia. The Western Australian mulga shrublands ecoregion lies to the west, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Botanical Name
A botanical name is a formal scientific name conforming to the '' International Code of Nomenclature for algae, fungi, and plants'' (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the ''International Code of Nomenclature for Cultivated Plants'' (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae ( Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." The purpose of a formal name is to have a single name that is accepted and used worldwide for a particular plant or plant group. For example, the botanical name ''Bellis perennis'' denotes a plant species which is native to most of the countries of Europe and the Middle East, where it has accumulated various names in many languages. Later, the plant was intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carle Thulka
Carle Thulka, officially Carle Thulka / Lake Maurice is a salt lake in South Australia. It is the largest of many salt lakes in the eastern end of the Great Victoria Desert. It is normally dry, except during and after periods of heavy rainfall. When it is full, the lake covers an area of around . It is part of the geological basin known as the Officer Basin. The smaller Lake Dey Dey is to the north. Since 1985, Carle Thulka is part of the lands belonging to the Maralinga Tjarutja, a southern branch of the Pitjantjatjara. The community of Oak Valley is near the western shore of the lake. The exposed surface of the lake normally consists of dry clay, silt or sand, covered with a salty crust. The area around Carle Thulka is very dry. Two wells have been drilled to the southeast and northwest of Carle Thulka, to search for uranium and other minerals. Both wells yield very low levels of groundwater. The water contains high levels of salt. It has also been found to cont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Capsule (botany)
In botany a capsule is a type of simple, dry, though rarely fleshy dehiscent fruit produced by many species of angiosperms (flowering plants). Origins and structure The capsule (Latin: ''capsula'', small box) is derived from a compound (multicarpeled) ovary. A capsule is a structure composed of two or more carpels. In (flowering plants), the term locule (or cell) is used to refer to a chamber within the fruit. Depending on the number of locules in the ovary, fruit can be classified as uni-locular (unilocular), bi-locular, tri-locular or multi-locular. The number of locules present in a gynoecium may be equal to or less than the number of carpels. The locules contain the ovules or seeds and are separated by septa. Dehiscence In most cases the capsule is dehiscent, i.e. at maturity, it splits apart (dehisces) to release the seeds within. A few capsules are indehiscent, for example those of ''Adansonia digitata'', ''Alphitonia'', and '' Merciera''. Capsules are often classifie ...
