Barbara Lynette Rye
Barbara Lynette Rye is an Australian botanist born in 1952. Barbara Rye has been associated with the Western Australian Herbarium, where her work as a taxonomist has been the source of many new descriptions of plants. The number of taxa recorded as described by women authors is historically very low, of the terrestrial plant species this amount is around three percent, yet in analysis published in 2019 Rye is amongst the ten most prolific women taxonomists. Born in Perth, Western Australia, she spent her childhood investigating the local flora and fauna of the Southwest Australia region, a biodiversity hotspot, and later began studies at the University of Western Australia. Barbara Rye entered the fields of zoology and botany, taking a special interest in genetics and evolutionary biology. The first description of a new species was a ''Darwinia'', a genus of the family Myrtaceae that Rye investigated for her doctoral thesis, separating '' Darwinia capitellata'' from a more widely ...

Comet Vale
Comet Vale is an abandoned town in Western Australia located in the Goldfield region of Western Australia located between Kalgoorlie and Laverton on the Goldfields Highway. It is within the Shire of Menzies. The town site was named after a comet that could be seen at about the time gold was discovered in the area. By 1895 the town had a population of approximately 500, and by 1897 the townspeople were demanding a post-office. The postmaster general instructed postmasters at Menzies and Googarrie prepare daily mail bags for Comet Vale which were then distributed at one of the stores in town. The ''Comet Vale Hotel'' was established some time prior to 1898. The town was gazetted in 1916. A prospector, Dan Baker is credited with the initial gold discovery. Two mines were in production in 1900 named ''Lady Margaret'' and ''Long tunnel''. The ''Gladsome'' mine was operating before 1905, and the Moss brothers built a 10-head stamp mill and ''Coonega'' at Comet Vale. Comet Vale wa ...

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 ...

Endemic Flora Of Western Australia
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

Micromyrtus
''Micromyrtus'' is a genus of flowering plants in the family Myrtaceae and is endemic to Australia. Plants in the genus ''Micromyrtus'' are shrubs with simple leaves arranged in opposite pairs, and white, pink or yellow flowers arranged in upper leaf axils, the flowers with five sepals five petals and five or ten stamens. Description Plants in the genus ''Micromyrtus'' are shrubs typically less than high. They have crowded, overlapping, simple leaves arranged in opposite pairs, oblong to lance-shaped and usually less than long. The flowers are arranged singly or in groups of up to three on a common peduncle, often forming clusters on the ends of branches. The flowers usually have five, (rarely six) small sepals and five (rarely six) white, pink or yellow, elliptic to round petals that are free from each other, and five or ten (rarely six or twelve) stamens. The fruit is a small, dry, indehiscent nut, usually containing a single seed. Taxonomy The genus ''Micromyrtus'' was fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Murchison Bioregion
The Murchison is a loosely defined area of Western Australia located within the interior of the Mid West region. It was the subject of a major gold rush in the 1890s and remains a significant mining district. The Murchison is also included as an interim Australian bioregion. The bioregion is loosely related to the catchment area of the Murchison River and has an area of . Geography The landscape is characterised by low hills and mesas, separated by colluvium flats and alluvial plains. The western portion of the bioregion is drained by the upper Murchison and Wooramel rivers, which drain westwards towards the coast.Anthony Desmond, Mark Cowan and Alanna Chant (2001).

Coolgardie Bioregion
Coolgardie is an Australian bioregion consisting of an area of low hills and plains of infertile sandy soil in Western Australia. It has an area of . It includes much of the Great Western Woodlands. Location and description This is a transition zone between the Mediterranean climate of Australia's south-west coast and the country's dry interior. The poor soil makes it unsuitable for agriculture but Coolgardie has been a gold and nickel mining area. It is bounded on the north by the arid Murchison bioregion, characterised by open Mulga woodlands and steppe. The low shrublands of the arid Nullarbor Plain lie to the east. The Mallee bioregion adjoins Coolgardie on the south. The Avon Wheatbelt bioregion is to the west. The Coolgardie bioregion, together with the coastal Hampton bioregion to the southeast, constitute the Coolgardie woodlands ecoregion defined by the World Wildlife Fund.

Botanical Nomenclature
Botanical nomenclature is the formal, scientific naming of plants. It is related to, but distinct from taxonomy (biology), taxonomy. Plant taxonomy is concerned with grouping and classifying plants; Botany, botanical nomenclature then provides names for the results of this process. The starting point for modern botanical nomenclature is Carl Linnaeus, Linnaeus' ''Species Plantarum'' of 1753. Botanical nomenclature is governed by the ''International Code of Nomenclature for algae, fungi, and plants'' (''ICNafp''), which replaces the ''International Code of Botanical Nomenclature'' (''ICBN''). Fossil plants are also covered by the code of nomenclature. Within the limits set by that code there is another set of rules, the ''International Code of Nomenclature for Cultivated Plants, International Code of Nomenclature for Cultivated Plants (ICNCP)'' which applies to plant cultivars that have been deliberately altered or selected by humans (see cultigen). Botanical nomenclature is indep ... [...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 ...

Nuytsia (journal)
''Nuytsia'' is a peer-reviewed scientific journal published by the Western Australian Herbarium. It publishes papers on systematic botany, giving preference to papers related to the flora of Western Australia. Nearly twenty percent of Western Australia's plant taxa 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 ... have been published in ''Nuytsia''. The journal was established in 1970 and has appeared irregularly since. Kevin Thiele and Juliet Wege have been in the editorial committee . ''Nuytsia'' is named after the monospecific genus ''Nuytsia'', whose only species is '' Nuytsia floribunda'', the Western Australian Christmas tree. Occasionally, the journal has published special issues, such as an issue in 2007 substantially expanding described species from Western Australia ...
