Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

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.

Flora Of Queensland
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] |

Nature Conservation Act 1992
The ''Nature Conservation Act 1992'' is an act of the Parliament of Queensland, Australia, that, together with subordinate legislation, provides for the legislative protection of Queensland's threatened biota. As originally published, it provided for biota to be declared ''presumed extinct'', ''endangered'', ''vulnerable'', ''rare'' or ''common''. In 2004 the act was amended to more closely align with the IUCN Red List categories: ''presumed extinct'' was changed to ''extinct in the wild'' and ''common'' was changed to ''least concern''. ''Near threatened'' was introduced as an eventual replacement for ''rare'', but the latter was to be phased out over time rather than immediately abandoned. The act is administered by the state's Environmental Protection Agency (EPA). There are provisions under the act which allow landholders to negotiate voluntary conservation agreements with the EPA. New regulations came into effect on 22 August 2020: Text may have been copied from this s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alpha, Queensland
Alpha is a rural town and a locality in the Barcaldine Region, Queensland, Australia. At the , the locality had a population of 559 people. Geography Alpha is in Central West Queensland. It lies on Alpha Creek. The Capricorn Highway runs through from east to west, and the Clermont-Alpha Road enters from the north-east. The Central Western railway line passes through the town, which is served by Alpha railway station. The town is a service centre for the surrounding pastoral properties and travellers on the highway. History The town of Alpha is situated approximately 400 kilometres to the west of Rockhampton, with the name being derived from Alpha Pastoral Station, established in 1863. This was a very large station, dominating the area and growing to more than 1,600 square kilometres by the 1890s. The area was originally visited and partly explored by the New South Wales Surveyor-General, Thomas Mitchell in 1846 and it was his reports that were to encourage settlement, pa ...

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] |
Lake Buchanan (Queensland)
Lake Buchanan is a flat salt lake at Pentland in North Queensland, Australia. It is approximately 28 km long and 8 km wide at its widest point, with a surface area of about 117 km2. It is part of the Thomson River catchment and part of the Desert Uplands bioregion. Lake Buchanan is different from all other salt lakes in Australia because it occurs at a high elevation - on the Great Dividing Range. The lake is shallow and the water tends to be brackish.(5 April 2011)Site Investment Guide: Lake Buchanan. Australian Government Land and Coasts. Retrieved on 12 July 2011. The land around the lake is used for grazing. Lake Buchanan contains a number of significant species which are newly discovered and most probably endemic. These include the Lake Buchanan button grass, fringing rush, Lake Buchanan fringe rush, ''Lawrenica buchananensis'' (Malvaceae), and Buchanan's fairy shrimp. The Lake Buchanan blue bush is a threatened species belonging to the genus ''Chenopodiu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Style (botany)
The stigma () is the receptive tip of a carpel, or of several fused carpels, in the gynoecium of a flower. Description The stigma, together with the style and ovary (typically called the stigma-style-ovary system) comprises the pistil, which is part of the gynoecium or female reproductive organ of a plant. The stigma itself forms the distal portion of the style, or stylodia, and is composed of , the cells of which are receptive to pollen. These may be restricted to the apex of the style or, especially in wind pollinated species, cover a wide surface. The stigma receives pollen and it is on the stigma that the pollen grain germinates. Often sticky, the stigma is adapted in various ways to catch and trap pollen with various hairs, flaps, or sculpturings. The pollen may be captured from the air (wind-borne pollen, anemophily), from visiting insects or other animals ( biotic pollination), or in rare cases from surrounding water (hydrophily). Stigma can vary from long and slen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myrtaceae
Myrtaceae, the myrtle family, is a family of dicotyledonous plants placed within the order Myrtales. Myrtle, pōhutukawa, bay rum tree, clove, guava, acca (feijoa), allspice, and eucalyptus are some notable members of this group. All species are woody, contain essential oils, and have flower parts in multiples of four or five. The leaves are evergreen, alternate to mostly opposite, simple, and usually entire (i.e., without a toothed margin). The flowers have a base number of five petals, though in several genera, the petals are minute or absent. The stamens are usually very conspicuous, brightly coloured, and numerous. Evolutionary history Scientists hypothesize that the family Myrtaceae arose between 60 and 56 million years ago (Mya) during the Paleocene era. Pollen fossils have been sourced to the ancient supercontinent Gondwana. The breakup of Gondwana during the Cretaceous period (145 to 66 Mya) geographically isolated disjunct taxa and allowed for rapid speciation; i ...
