Eucalyptus Nigrifunda
''Eucalyptus nigrifunda'', commonly known as desert wandoo, is a species of tree that is endemic to a small area in central Western Australia. It has smooth reddish brown bark with some rough, flaky black bark near the base of the trunk, lance-shaped adult leaves, flower buds in groups of nine, white flowers and cylindrical to barrel-shaped fruit. Description ''Eucalyptus nigrifunda'' is a tree that typically grows to a height of and forms a lignotuber. It has rough, flaky black bark on the base of the trunk, smooth reddish brown bark above. Adult leaves are lance-shaped, the same shade of dull bluish green on both sides, long and wide, tapering to a petiole long. The flower buds are arranged in leaf axils in groups of nine on an unbranched peduncle long, the individual buds on pedicels about long. Mature buds are spindle-shaped, long and wide with a conical to horn-shaped operculum. Flowering has been recorded in July and the flowers are white. The fruit is a woody, cyl ...

Ian Brooker
Murray Ian Hill Brooker Order of Australia, AM (2 June 1934 – 25 June 2016), better known as Ian Brooker, was an Australian botanist. He was widely recognised as the leading authority on the genus ''Eucalyptus''. Ian Brooker was born in Adelaide, South Australia on 2 June 1934. He obtained a B.Ag.Sc. from the University of Adelaide, and a MSc and D.Sc. from the Australian National University in Canberra. He worked with the Soil Conservation Branch of the Department of Agriculture in South Australia from 1957 to 1963; then joined the Department of Botany at the Australian National University until 1969; and then spent a year with the Western Australian Herbarium. In 1970, Brooker joined the Forest Research Institute in Canberra, now part of CSIRO. His research since then has specialised in the genus ''Eucalyptus'', especially its Taxonomy (biology), taxonomy. He travelled widely throughout Australia collecting specimens, and published 100 research papers, 180 leaflets, and fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Granite
Granite ( ) is a coarse-grained (phanerite, phaneritic) intrusive rock, intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dike (geology), dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF diagram, QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) conta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Ian Brooker
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Described In 1991
Plants are the eukaryotes that form the kingdom Plantae; they are predominantly photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants (hornworts, liverworts, mosses, lycophytes, ferns, conifers and other gymnosperm ...

Eucalyptus
''Eucalyptus'' () is a genus of more than 700 species of flowering plants in the family Myrtaceae. Most species of ''Eucalyptus'' are trees, often Mallee (habit), mallees, and a few are shrubs. Along with several other genera in the tribe Eucalypteae, including ''Corymbia'' and ''Angophora'', they are commonly known as eucalypts or "gum trees". Plants in the genus ''Eucalyptus'' have bark that is either smooth, fibrous, hard, or stringy and leaves that have oil Gland (botany), glands. The sepals and petals are fused to form a "cap" or Operculum (botany), operculum over the stamens, hence the name from Greek ''eû'' ("well") and ''kaluptós'' ("covered"). The fruit is a woody Capsule (botany), capsule commonly referred to as a "gumnut". Most species of ''Eucalyptus'' are Indigenous (ecology), native to Australia, and every state and territory has representative species. About three-quarters of Australian forests are eucalypt forests. Many eucalypt species have adapted to wildfire, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trees Of Australia
The flora of Australia comprises a vast assemblage of plant species estimated to over 21,000 vascular and 14,000 non-vascular plants, 250,000 species of fungi and over 3,000 lichens. The flora has strong affinities with the flora of Gondwana, and below the family level has a highly endemic angiosperm flora whose diversity was shaped by the effects of continental drift and climate change since the Cretaceous. Prominent features of the Australian flora are adaptations to aridity and fire which include scleromorphy and serotiny. These adaptations are common in species from the large and well-known families Proteaceae (''Banksia''), Myrtaceae (''Eucalyptus'' - gum trees), and Fabaceae (''Acacia'' - wattle). The arrival of humans around 50,000 years ago and the settlement by Europeans from 1788, has had a significant impact on the flora. The use of fire-stick farming by Aboriginal people led to significant changes in the distribution of plant species over time, and the large-scal ...

Eucalypts Of Western Australia
Eucalypt is any woody plant with capsule fruiting bodies belonging to one of seven closely related genera (of the tribe Eucalypteae) found across Australia: ''Eucalyptus'', ''Corymbia'', ''Angophora'', '' Stockwellia'', ''Allosyncarpia'', '' Eucalyptopsis'' and '' Arillastrum''. In Australia, they are commonly known as gum trees or stringybarks. Taxonomy For an example of changing historical perspectives, in 1991, largely genetic evidence indicated that some prominent ''Eucalyptus'' species were actually more closely related to ''Angophora'' than to other eucalypts; they were accordingly split off into the new genus ''Corymbia''. Although separate, all of these genera and their species are allied and it remains the standard to refer to the members of all seven genera ''Angophora'', ''Corymbia'', ''Eucalyptus'', ''Stockwellia'', ''Allosyncarpia'', ''Eucalyptopsis'' and ''Arillastrum'' as "eucalypts" or as the eucalypt group. The extant genera ''Stockwellia'', ''Allosyncarpia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 Western Australian Herbarium is the state Herbarium, situated in Perth, the capital of Western Australia. It houses a collection of more than 845,000 dried specimens of plants, algae, bryophytes (mosses, liverworts and hornworts), lichens, fu .... 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 n ...

Great Victoria Desert
The Great Victoria Desert is a sparsely populated desert ecoregion and Interim Biogeographic Regionalisation for Australia, 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 travelled 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 lake (geography), 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 ...
