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 ...

Index Kewensis
The 1893 ''Index Kewensis'' (IK), maintained by the Royal Botanic Gardens, Kew, is a publication that aims to register all botanical names for seed plants at the rank of species and genera. It later came to include names of taxonomic families and ranks below that of species. The ''Index'' is currently maintained as part of the International Plant Names Index in combination with the Gray Herbarium and Australian Plant Name indexes. This database is anticipated to complete the task of creating a complete list of plant names, although it does not determine which are accepted species names. History The preparation for this venture was made by Benjamin Daydon Jackson of the Linnaean Society, directed by Joseph Dalton Hooker at Kew. Charles Darwin provided the funding for the indexing project. When he died in 1882 his will stipulated that provision be made for £250 per annum over a 5-year period. In providing citations of plant names, the starting point was taken from 1753 onward ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plants Described In 1893
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 los ...

Government Of Western Australia
The Government of Western Australia, formally referred to as His Majesty's Government of Western Australia, is the Australian state democratic administrative authority of Western Australia. It is also commonly referred to as the WA Government or the Western Australian Government. The Government of Western Australia, a parliamentary constitutional monarchy, was formed in 1890 as prescribed in its Constitution, as amended from time to time. Since the Federation of Australia in 1901, Western Australia has been a state of the Commonwealth of Australia, and the Constitution of Australia regulates its relationship with the Commonwealth. Under the Australian Constitution, Western Australia ceded legislative and judicial supremacy to the Commonwealth, but retained powers in all matters not in conflict with the Commonwealth.

Declared Rare And Priority Flora List
The Declared Rare and Priority Flora List is the system by which Western Australia's conservation flora are given a priority. Developed by the Government of Western Australia's Department of Environment and Conservation, it was used extensively within the department, including the Western Australian Herbarium. The herbarium's journal, ''Nuytsia'', which has published over a quarter of the state's conservation taxa, requires a conservation status to be included in all publications of new Western Australian taxa that appear to be rare or endangered. The system defines six levels of priority taxa: ;X: Threatened (Declared Rare Flora) – Presumed Extinct Taxa: These are taxa that are thought to be extinct, either because they have not been collected for over 50 years despite thorough searching, or because all known wild populations have been destroyed. They have been declared as such in accordance with the Wildlife Conservation Act 1950, and are therefore afforded legislative protecti ...

Lake Barlee
Lake Barlee is an intermittent salt lake. With a surface area of , it is the second largest lake in Western Australia. Description Lake Barlee is situated on the Yilgarn block southeast of Youanmi and north of Bullfinch, on the border between the shires of Sandstone and Menzies. It is more than from west to east, and about from north to south. Lake Barlee and other lakes in the area are cenozoic palaeovalleys, fed predominantly by groundwater flowing through ancient palaeochannels. The channels are filled with calcretes and alluvial clay-quartz units. Like most of the clay playas in the area, it is usually dry but can fill when tropical cyclones become rain-bearing depressions after they cross the coast. It fills about once every ten years on average, after which the water usually persists for another six to nine months. When it is inundated, it becomes an important breeding site for waterbirds. Lake Barlee receives water from direct rainfall and inflow from a multitude ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Specific Epithet
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] |
Benjamin Daydon Jackson
Benjamin Daydon Jackson (3 April 1846 – 12 October 1927) was a pioneering botanist and taxonomer who wrote the first volume of ''Index Kewensis'' to include all the flowering plants. Biography Jackson was the eldest child of Benjamin Daydon Jackson (''c.''1806-1855) and Elizabeth Gaze (b.''c.''1815), born in London and educated at private schools. He is perhaps best known as the compiler of ''Index Kewensis'', a reference book which appeared from 1893 to 1895, and which was at once accepted as authority throughout the world for names of flowering plants. In 1880 he was elected secretary of the Linnaean Society. Works Besides the ''Index Kewensis'', he wrote: * ''Guide to the Literature of Botany'' (1881) * ''Vegetable Technology'' (1882) * ''Glossary of Botanical Terms'' (1900) References Jackson, Benjamin Daydon (1846-1927)at International Plant Names Index The International Plant Names Index (IPNI) describes itself as "a database of the names and associated basic ...
